-
-You are an expert Python developer specializing in implementing specifications into working Python services and APIs. You have deep expertise in Python language features, FastAPI, DBOS workflows, database operations, and the Basic Memory Cloud backend architecture.
-
-**Primary Role: Backend Implementation Agent**
-You implement specifications into working Python code and services. You read specs from basic-memory, implement the requirements using modern Python patterns, and update specs with implementation progress and decisions.
-
-**Core Responsibilities:**
-
-**Specification Implementation:**
-- Read specs using basic-memory MCP tools to understand backend requirements
-- Implement Python services, APIs, and workflows that fulfill spec requirements
-- Update specs with implementation progress, decisions, and completion status
-- Document any architectural decisions or modifications needed during implementation
-
-**Python/FastAPI Development:**
-- Create FastAPI applications with proper middleware and dependency injection
-- Implement DBOS workflows for durable, long-running operations
-- Design database schemas and implement repository patterns
-- Handle authentication, authorization, and security requirements
-- Implement async/await patterns for optimal performance
-
-**Backend Implementation Process:**
-1. **Read Spec**: Use `mcp__basic-memory__read_note` to get spec requirements
-2. **Analyze Existing Patterns**: Study codebase architecture and established patterns before implementing
-3. **Follow Modular Structure**: Create separate modules/routers following existing conventions
-4. **Implement**: Write Python code following spec requirements and codebase patterns
-5. **Test**: Create tests that validate spec success criteria
-6. **Update Spec**: Document completion and any implementation decisions
-7. **Validate**: Run tests and ensure integration works correctly
-
-**Technical Standards:**
-- Follow PEP 8 and modern Python conventions
-- Use type hints throughout the codebase
-- Implement proper error handling and logging
-- Use async/await for all database and external service calls
-- Write comprehensive tests using pytest
-- Follow security best practices for web APIs
-- Document functions and classes with clear docstrings
-
-**Codebase Architecture Patterns:**
-
-**CLI Structure Patterns:**
-- Follow existing modular CLI pattern: create separate CLI modules (e.g., `upload_cli.py`) instead of adding commands directly to `main.py`
-- Existing examples: `polar_cli.py`, `tenant_cli.py` in `apps/cloud/src/basic_memory_cloud/cli/`
-- Register new CLI modules using `app.add_typer(new_cli, name="command", help="description")`
-- Maintain consistent command structure and help text patterns
-
-**FastAPI Router Patterns:**
-- Create dedicated routers for logical endpoint groups instead of adding routes directly to main app
-- Place routers in dedicated files (e.g., `apps/api/src/basic_memory_cloud_api/routers/webdav_router.py`)
-- Follow existing middleware and dependency injection patterns
-- Register routers using `app.include_router(router, prefix="/api-path")`
-
-**Modular Organization:**
-- Always analyze existing codebase structure before implementing new features
-- Follow established file organization and naming conventions
-- Create separate modules for distinct functionality areas
-- Maintain consistency with existing architectural decisions
-- Preserve separation of concerns across service boundaries
-
-**Pattern Analysis Process:**
-1. Examine similar existing functionality in the codebase
-2. Identify established patterns for file organization and module structure
-3. Follow the same architectural approach for consistency
-4. Create new modules/routers following existing conventions
-5. Integrate new code using established registration patterns

+# AGENTS.md - Basic Memory Project Guide
+
+## Project Overview
+
+Basic Memory is a local-first knowledge management system built on the Model Context Protocol (MCP). It enables
+bidirectional communication between LLMs (like Claude) and markdown files, creating a personal knowledge graph that can
+be traversed using links between documents.
+
+## CODEBASE DEVELOPMENT
+
+### Project information
+
+See the [README.md](README.md) file for a project overview.
+
+### Build and Test Commands
+
+- Install: `just install` or `pip install -e ".[dev]"`
+- Run all tests (SQLite + Postgres): `just test`
+- Run all tests against SQLite: `just test-sqlite`
+- Run all tests against Postgres: `just test-postgres` (uses testcontainers)
+- Run unit tests (SQLite): `just test-unit-sqlite`
+- Run unit tests (Postgres): `just test-unit-postgres`
+- Run integration tests (SQLite): `just test-int-sqlite`
+- Run integration tests (Postgres): `just test-int-postgres`
+- Run impacted tests: `just testmon` (pytest-testmon)
+- Run MCP smoke test: `just test-smoke`
+- Fast local loop: `just fast-check`
+- Local consistency check: `just doctor`
+- Generate HTML coverage: `just coverage`
+- Single test: `pytest tests/path/to/test_file.py::test_function_name`
+- Run benchmarks: `pytest test-int/test_sync_performance_benchmark.py -v -m "benchmark and not slow"`
+- Lint: `just lint` or `ruff check . --fix`
+- Type check: `just typecheck` or `uv run pyright`
+- Type check (supplemental): `just typecheck-ty` or `uv run ty check src/`
+- Format: `just format` or `uv run ruff format .`
+- Run all code checks: `just check` (runs lint, format, typecheck, test)
+- Create db migration: `just migration "Your migration message"`
+- Run development MCP Inspector: `just run-inspector`
+
+**Note:** Project requires Python 3.12+ (uses type parameter syntax and `type` aliases introduced in 3.12)
+
+**Postgres Testing:** Uses [testcontainers](https://testcontainers-python.readthedocs.io/) which automatically spins up a Postgres instance in Docker. No manual database setup required - just have Docker running.
+
+**Doctor Note:** `just doctor` runs with a temporary HOME/config so it won't touch your local Basic Memory settings. It leaves temp dirs in `/tmp` (safe to ignore or remove).
+
+**Testmon Note:** When no files have changed, `just testmon` may collect 0 tests. That's expected and means no impacted tests were detected.
+
+### Code/Test/Verify Loop (fast path)
+
+1) **Code:** make changes.
+2) **Test:** `just fast-check` (lint/format/typecheck + impacted tests + MCP smoke).
+3) **Verify:** `just doctor` (end-to-end file ↔ DB loop in a temp project).
+4) **Full gate (when needed):** `just test` or `just check` for SQLite + Postgres.
+
+If testmon is “cold,” the first run may be long. Subsequent runs get much faster.
+
+### Test Structure
+
+- `tests/` - Unit tests for individual components (mocked, fast)
+- `test-int/` - Integration tests for real-world scenarios (no mocks, realistic)
+- Both directories are covered by unified coverage reporting
+- Benchmark tests in `test-int/` are marked with `@pytest.mark.benchmark`
+- Slow tests are marked with `@pytest.mark.slow`
+- Smoke tests are marked with `@pytest.mark.smoke`
+
+### Code Style Guidelines
+
+- Line length: 100 characters max
+- Python 3.12+ with full type annotations (uses type parameters and type aliases)
+- Format with ruff (consistent styling)
+- Import order: standard lib, third-party, local imports
+- Naming: snake_case for functions/variables, PascalCase for classes
+- Prefer async patterns with SQLAlchemy 2.0
+- Use Pydantic v2 for data validation and schemas
+- CLI uses Typer for command structure
+- API uses FastAPI for endpoints
+- Follow the repository pattern for data access
+- Tools communicate to api routers via the httpx ASGI client (in process)
+
+### Code Change Guidelines
+
+- **Full file read before edits**: Before editing any file, read it in full first to ensure complete context; partial reads lead to corrupted edits
+- **Minimize diffs**: Prefer the smallest change that satisfies the request. Avoid unrelated refactors or style rewrites unless necessary for correctness
+- **No speculative getattr**: Never use `getattr(obj, "attr", default)` when unsure about attribute names. Check the class definition or source code first
+- **Fail fast**: Write code with fail-fast logic by default. Do not swallow exceptions with errors or warnings
+- **No fallback logic**: Do not add fallback logic unless explicitly told to and agreed with the user
+- **No guessing**: Do not say "The issue is..." before you actually know what the issue is. Investigate first.
+
+### Literate Programming Style
+
+Code should tell a story. Comments must explain the "why" and narrative flow, not just the "what".
+
+**Section Headers:**
+For files with multiple phases of logic, add section headers so the control flow reads like chapters:
+```python
+# --- Authentication ---
+# ... auth logic ...
+
+# --- Data Validation ---
+# ... validation logic ...
+
+# --- Business Logic ---
+# ... core logic ...
+```
+
+**Decision Point Comments:**
+For conditionals that materially change behavior (gates, fallbacks, retries, feature flags), add comments with:
+- **Trigger**: what condition causes this branch
+- **Why**: the rationale (cost, correctness, UX, determinism)
+- **Outcome**: what changes downstream
+
+```python
+# Trigger: project has no active sync watcher
+# Why: avoid duplicate file system watchers consuming resources
+# Outcome: starts new watcher, registers in active_watchers dict
+if project_id not in active_watchers:
+    start_watcher(project_id)
+```
+
+**Constraint Comments:**
+If code exists because of a constraint (async requirements, rate limits, schema compatibility), explain the constraint near the code:
+```python
+# SQLite requires WAL mode for concurrent read/write access
+connection.execute("PRAGMA journal_mode=WAL")
+```
+
+**What NOT to Comment:**
+Avoid comments that restate obvious code:
+```python
+# Bad - restates code
+counter += 1  # increment counter
+
+# Good - explains why
+counter += 1  # track retries for backoff calculation
+```
+
+### Codebase Architecture
+
+See [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) for detailed architecture documentation.
+
+**Directory Structure:**
+- `/alembic` - Alembic db migrations
+- `/api` - FastAPI REST endpoints + `container.py` composition root
+- `/cli` - Typer CLI + `container.py` composition root
+- `/deps` - Feature-scoped FastAPI dependencies (config, db, projects, repositories, services, importers)
+- `/importers` - Import functionality for Claude, ChatGPT, and other sources
+- `/markdown` - Markdown parsing and processing
+- `/mcp` - MCP server + `container.py` composition root + `clients/` typed API clients
+- `/models` - SQLAlchemy ORM models
+- `/repository` - Data access layer
+- `/schemas` - Pydantic models for validation
+- `/services` - Business logic layer
+- `/sync` - File synchronization services + `coordinator.py` for lifecycle management
+
+**Composition Roots:**
+Each entrypoint (API, MCP, CLI) has a composition root that:
+- Reads `ConfigManager` (the only place that reads global config)
+- Resolves runtime mode via `RuntimeMode` enum (TEST > CLOUD > LOCAL)
+- Provides dependencies to downstream code explicitly
+
+**Typed API Clients (MCP):**
+MCP tools use typed clients in `mcp/clients/` to communicate with the API:
+- `KnowledgeClient` - Entity CRUD operations
+- `SearchClient` - Search operations
+- `MemoryClient` - Context building
+- `DirectoryClient` - Directory listing
+- `ResourceClient` - Resource reading
+- `ProjectClient` - Project management
+
+Flow: MCP Tool → Typed Client → HTTP API → Router → Service → Repository
+
+### Development Notes
+
+- MCP tools are defined in src/basic_memory/mcp/tools/
+- MCP prompts are defined in src/basic_memory/mcp/prompts/
+- MCP tools should be atomic, composable operations
+- Use `textwrap.dedent()` for multi-line string formatting in prompts and tools
+- MCP Prompts are used to invoke tools and format content with instructions for an LLM
+- Schema changes require Alembic migrations
+- SQLite is used for indexing and full text search, files are source of truth
+- Testing uses pytest with asyncio support (strict mode)
+- Unit tests (`tests/`) use mocks when necessary; integration tests (`test-int/`) use real implementations
+- By default, tests run against SQLite (fast, no Docker needed)
+- Set `BASIC_MEMORY_TEST_POSTGRES=1` to run against Postgres (uses testcontainers - Docker required)
+- Each test runs in a standalone environment with isolated database and tmp_path directory
+- CI runs SQLite and Postgres tests in parallel for faster feedback
+- Performance benchmarks are in `test-int/test_sync_performance_benchmark.py`
+- Use pytest markers: `@pytest.mark.benchmark` for benchmarks, `@pytest.mark.slow` for slow tests
+- **Coverage must stay at 100%**: Write tests for new code. Only use `# pragma: no cover` when tests would require excessive mocking (e.g., TYPE_CHECKING blocks, error handlers that need failure injection, runtime-mode-dependent code paths)
+
+### Async Client Pattern (Important!)
+
+**MCP tools use `get_project_client()` for per-project routing:**
+
+```python
+from basic_memory.mcp.project_context import get_project_client
+
+@mcp.tool()
+async def my_tool(project: str | None = None, context: Context | None = None):
+    async with get_project_client(project, context) as (client, active_project):
+        # client is routed based on project's mode (local ASGI or cloud HTTP)
+        response = await call_get(client, "/path")
+        return response
+```
+
+**CLI commands and non-project-scoped code use `get_client()` directly:**
+
+```python
+from basic_memory.mcp.async_client import get_client
+
+async def my_cli_command():
+    async with get_client() as client:
+        response = await call_get(client, "/path")
+        return response
+
+# Per-project routing (when project name is known):
+async with get_client(project_name="research") as client:
+    ...
+```
+
+**Do NOT use:**
+- ❌ `from basic_memory.mcp.async_client import client` (deprecated module-level client)
+- ❌ Manual auth header management
+- ❌ `inject_auth_header()` (deleted)
+- ❌ Separate `get_client()` + `get_active_project()` in MCP tools (use `get_project_client()` instead)
+
+**Key principles:**
+- Auth happens at client creation, not per-request
+- Proper resource management via context managers
+- Per-project routing: each project can be LOCAL or CLOUD independently
+- Cloud projects use API key (`cloud_api_key` in config) as Bearer token
+- Routing priority: factory injection > force-local > per-project cloud > global cloud > local ASGI
+- Factory pattern enables dependency injection for cloud consolidation
+
+**For cloud app integration:**
+```python
+from basic_memory.mcp import async_client
+
+# Set custom factory before importing tools
+async_client.set_client_factory(your_custom_factory)
+```
+
+See SPEC-16 for full context manager refactor details.

+
+### Cloud Features (v0.15.0+)
+
+Basic Memory now supports cloud synchronization and storage (requires active subscription):
+
+**Authentication:**
+- JWT-based authentication with subscription validation
+- Secure session management with token refresh
+- Support for multiple cloud projects
+
+**Bidirectional Sync:**
+- rclone bisync integration for two-way synchronization
+- Conflict resolution and integrity verification
+- Real-time sync with change detection
+- Mount/unmount cloud storage for direct file access
+
+**Cloud Project Management:**
+- Create and manage projects in the cloud
+- Toggle between local and cloud modes
+- Per-project sync configuration
+- Subscription-based access control
+
+**Security & Performance:**
+- Removed .env file loading for improved security
+- .gitignore integration (respects gitignored files)
+- WAL mode for SQLite performance
+- Background relation resolution (non-blocking startup)
+- API performance optimizations (SPEC-11)
+
+**Per-Project Cloud Routing:**
+
+Individual projects can be routed through the cloud while others stay local, using an API key:
+
+```bash
+# Save API key and set project to cloud mode
+basic-memory cloud set-key bmc_abc123...
+basic-memory project set-cloud research    # route through cloud
+basic-memory project set-local research    # revert to local
+```
+
+MCP tools use `get_project_client()` which automatically routes based on the project's mode. Cloud projects use the `cloud_api_key` from config as Bearer token.
+
+**CLI Routing Flags (Global Cloud Mode):**
+
+When global cloud mode is enabled, CLI commands route to the cloud API by default. Use `--local` and `--cloud` flags to override:
+
+```bash
+# Force local routing (ignore cloud mode)
+basic-memory status --local
+basic-memory project list --local
+
+# Force cloud routing (when cloud mode is disabled)
+basic-memory status --cloud
+basic-memory project info my-project --cloud
+```
+
+Key behaviors:
+- The local MCP server (`basic-memory mcp`) automatically uses local routing
+- This allows simultaneous use of local Claude Desktop and cloud-based clients
+- Some commands (like `project default`, `project sync-config`, `project move`) require `--local` in cloud mode since they modify local configuration
+- Environment variable `BASIC_MEMORY_FORCE_LOCAL=true` forces local routing globally
+- Per-project cloud routing via API key works independently of global cloud mode
+
+## AI-Human Collaborative Development
+
+Basic Memory emerged from and enables a new kind of development process that combines human and AI capabilities. Instead
+of using AI just for code generation, we've developed a true collaborative workflow:
+
+1. AI (LLM) writes initial implementation based on specifications and context
+2. Human reviews, runs tests, and commits code with any necessary adjustments
+3. Knowledge persists across conversations using Basic Memory's knowledge graph
+4. Development continues seamlessly across different AI sessions with consistent context
+5. Results improve through iterative collaboration and shared understanding
+
+This approach has allowed us to tackle more complex challenges and build a more robust system than either humans or AI
+could achieve independently.
+
+**Problem-Solving Guidance:**
+- If a solution isn't working after reasonable effort, suggest alternative approaches
+- Don't persist with a problematic library or pattern when better alternatives exist
+- Example: When py-pglite caused cascading test failures, switching to testcontainers-postgres was the right call
+
+## GitHub Integration
+
+Basic Memory has taken AI-Human collaboration to the next level by integrating Claude directly into the development workflow through GitHub:
+
+### GitHub MCP Tools
+
+Using the GitHub Model Context Protocol server, Claude can now:
+
+- **Repository Management**:
+  - View repository files and structure
+  - Read file contents
+  - Create new branches
+  - Create and update files
+
+- **Issue Management**:
+  - Create new issues
+  - Comment on existing issues
+  - Close and update issues
+  - Search across issues
+
+- **Pull Request Workflow**:
+  - Create pull requests
+  - Review code changes
+  - Add comments to PRs
+
+This integration enables Claude to participate as a full team member in the development process, not just as a code generation tool. Claude's GitHub account ([bm-claudeai](https://github.com/bm-claudeai)) is a member of the Basic Machines organization with direct contributor access to the codebase.
+
+### Collaborative Development Process
+
+With GitHub integration, the development workflow includes:
+
+1. **Direct code review** - Claude can analyze PRs and provide detailed feedback
+2. **Contribution tracking** - All of Claude's contributions are properly attributed in the Git history
+3. **Branch management** - Claude can create feature branches for implementations
+4. **Documentation maintenance** - Claude can keep documentation updated as the code evolves
+5. **Code Commits**: ALWAYS sign off commits with `git commit -s`
+6. **Pull Request Titles**: PR titles must follow the semantic format enforced by `.github/workflows/pr-title.yml`: `type(scope): summary`
+   - Allowed types: `feat`, `fix`, `chore`, `docs`, `style`, `refactor`, `perf`, `test`, `build`, `ci`
+   - Allowed scopes: `core`, `cli`, `api`, `mcp`, `sync`, `ui`, `deps`, `installer`
+   - Example: `fix(cli): propagate cloud workspace routing`
+
+This level of integration represents a new paradigm in AI-human collaboration, where the AI assistant becomes a full-fledged team member rather than just a tool for generating code snippets.

-# CLAUDE.md - Basic Memory Project Guide
-
-## Project Overview
-
-Basic Memory is a local-first knowledge management system built on the Model Context Protocol (MCP). It enables
-bidirectional communication between LLMs (like Claude) and markdown files, creating a personal knowledge graph that can
-be traversed using links between documents.
-
-## CODEBASE DEVELOPMENT
-
-### Project information
-
-See the [README.md](README.md) file for a project overview.
-
-### Build and Test Commands
-
-- Install: `make install` or `pip install -e ".[dev]"`
-- Run tests: `uv run pytest -p pytest_mock -v` or `make test`
-- Single test: `pytest tests/path/to/test_file.py::test_function_name`
-- Lint: `make lint` or `ruff check . --fix`
-- Type check: `make type-check` or `uv run pyright`
-- Format: `make format` or `uv run ruff format .`
-- Run all code checks: `make check` (runs lint, format, type-check, test)
-- Create db migration: `make migration m="Your migration message"`
-- Run development MCP Inspector: `make run-inspector`
-
-### Code Style Guidelines
-
-- Line length: 100 characters max
-- Python 3.12+ with full type annotations
-- Format with ruff (consistent styling)
-- Import order: standard lib, third-party, local imports
-- Naming: snake_case for functions/variables, PascalCase for classes
-- Prefer async patterns with SQLAlchemy 2.0
-- Use Pydantic v2 for data validation and schemas
-- CLI uses Typer for command structure
-- API uses FastAPI for endpoints
-- Follow the repository pattern for data access
-- Tools communicate to api routers via the httpx ASGI client (in process)
-
-### Codebase Architecture
-
-- `/alembic` - Alembic db migrations
-- `/api` - FastAPI implementation of REST endpoints
-- `/cli` - Typer command-line interface
-- `/markdown` - Markdown parsing and processing
-- `/mcp` - Model Context Protocol server implementation
-- `/models` - SQLAlchemy ORM models
-- `/repository` - Data access layer
-- `/schemas` - Pydantic models for validation
-- `/services` - Business logic layer
-- `/sync` - File synchronization services
-
-### Development Notes
-
-- MCP tools are defined in src/basic_memory/mcp/tools/
-- MCP prompts are defined in src/basic_memory/mcp/prompts/
-- MCP tools should be atomic, composable operations
-- Use `textwrap.dedent()` for multi-line string formatting in prompts and tools
-- MCP Prompts are used to invoke tools and format content with instructions for an LLM
-- Schema changes require Alembic migrations
-- SQLite is used for indexing and full text search, files are source of truth
-- Testing uses pytest with asyncio support (strict mode)
-- Test database uses in-memory SQLite
-- Avoid creating mocks in tests in most circumstances.
-- Each test runs in a standalone environment with in memory SQLite and tmp_file directory
-
-## BASIC MEMORY PRODUCT USAGE
-
-### Knowledge Structure

-- Observation: A categorized fact about an entity (`- [category] content`)
-- Relation: A directional link between entities (`- relation_type [[Target]]`)
-- Frontmatter: YAML metadata at the top of markdown files
-- Knowledge representation follows precise markdown format:
-    - Observations with [category] prefixes
-    - Relations with WikiLinks [[Entity]]
-    - Frontmatter with metadata
-
-### Basic Memory Commands
-
-- Sync knowledge: `basic-memory sync` or `basic-memory sync --watch`

 ## Testing Guidelines
 
-- **Coverage Target**: We aim for 100% test coverage for all code
+### Test Structure
+
+Basic Memory uses two test directories with unified coverage reporting:
+
+- **`tests/`**: Unit tests that test individual components in isolation
+  - Fast execution with extensive mocking
+  - Test individual functions, classes, and modules
+  - Run with: `just test-unit` (no coverage, fast)
+
+- **`test-int/`**: Integration tests that test real-world scenarios
+  - Test full workflows with real database and file operations
+  - Include performance benchmarks
+  - More realistic but slower than unit tests
+  - Run with: `just test-int` (no coverage, fast)
+
+### Running Tests
+
+```bash
+# Run all tests with unified coverage report
+just test
+
+# Run only unit tests (fast iteration)
+just test-unit
+
+# Run only integration tests
+just test-int
+
+# Generate HTML coverage report
+just coverage
+
+# Run specific test
+pytest tests/path/to/test_file.py::test_function_name
+
+# Run tests excluding benchmarks
+pytest -m "not benchmark"
+
+# Run only benchmark tests
+pytest -m benchmark test-int/test_sync_performance_benchmark.py
+```
+
+### Performance Benchmarks
+
+The `test-int/test_sync_performance_benchmark.py` file contains performance benchmarks that measure sync and indexing speed:
+
+- `test_benchmark_sync_100_files` - Small repository performance
+- `test_benchmark_sync_500_files` - Medium repository performance
+- `test_benchmark_sync_1000_files` - Large repository performance (marked slow)
+- `test_benchmark_resync_no_changes` - Re-sync performance baseline
+
+Run benchmarks with:
+```bash
+# Run all benchmarks (excluding slow ones)
+pytest test-int/test_sync_performance_benchmark.py -v -m "benchmark and not slow"
+
+# Run all benchmarks including slow ones
+pytest test-int/test_sync_performance_benchmark.py -v -m benchmark
+
+# Run specific benchmark
+pytest test-int/test_sync_performance_benchmark.py::test_benchmark_sync_100_files -v
+```
+
+See `test-int/BENCHMARKS.md` for detailed benchmark documentation.
+
+### Testing Best Practices
+
+- **Coverage Target**: We aim for high test coverage for all code
 - **Test Framework**: Use pytest for unit and integration tests
-- **Mocking**: Use pytest-mock for mocking dependencies only when necessary
+- **Mocking**: Avoid mocking in integration tests; use sparingly in unit tests
 - **Edge Cases**: Test both normal operation and edge cases
 - **Database Testing**: Use in-memory SQLite for testing database operations
 - **Fixtures**: Use async pytest fixtures for setup and teardown
+- **Markers**: Use `@pytest.mark.benchmark` for benchmarks, `@pytest.mark.slow` for slow tests

+# Note Format Reference
+
+Every document in Basic Memory is a plain Markdown file. Files are the source of truth — changes to files automatically update the knowledge graph in the database. You maintain complete ownership, files work with git, and knowledge persists independently of any AI conversation.
+
+## Document Structure
+
+A note has three parts: YAML frontmatter, content (observations), and relations.
+
+```markdown
+---
+title: Coffee Brewing Methods
+type: note
+tags: [coffee, brewing]
+permalink: coffee-brewing-methods
+---
+
+# Coffee Brewing Methods
+
+## Observations
+- [method] Pour over provides more flavor clarity than French press
+- [technique] Water temperature at 205°F extracts optimal compounds #brewing
+- [preference] Ethiopian beans work well with lighter roasts (personal experience)
+
+## Relations
+- relates_to [[Coffee Bean Origins]]
+- requires [[Proper Grinding Technique]]
+- contrasts_with [[Tea Brewing Methods]]
+```
+
+The `## Observations` and `## Relations` headings are conventional but not required — the parser detects observations and relations by their syntax patterns anywhere in the document.
+
+## Frontmatter
+
+YAML metadata between `---` fences at the top of the file.
+
+| Field | Required | Default | Description |
+|-------|----------|---------|-------------|
+| `title` | No | filename stem | Used for linking and references. Auto-set from filename if missing. |
+| `type` | No | `note` | Entity type. Used for schema resolution and filtering. |
+| `tags` | No | `[]` | List or comma-separated string. Used for organization and search. |
+| `permalink` | No | generated from title | Stable identifier. Persists even if the file moves. |
+| `schema` | No | none | Schema attachment — dict (inline), string (reference), or omitted (implicit). |
+
+Custom fields are allowed. Any key not in the standard set is stored as `entity_metadata` and indexed for search and filtering.
+
+```yaml
+---
+title: Paul Graham
+type: Person
+tags: [startups, essays, lisp]
+permalink: paul-graham
+status: active
+source: wikipedia
+---
+```
+
+Here `status` and `source` are custom fields stored in `entity_metadata`.
+
+### Frontmatter Value Handling
+
+YAML automatically converts some values to native types. Basic Memory normalizes them:
+
+- Date strings (`2025-10-24`) → kept as ISO format strings
+- Numbers (`1.0`) → converted to strings
+- Booleans (`true`) → converted to strings (`"True"`)
+- Lists and dicts → preserved, items normalized recursively
+
+This prevents errors when downstream code expects string values.
+
+## Observations
+
+An observation is a categorized fact about the entity. Written as a Markdown list item.
+
+**Syntax:**
+
+```
+- [category] content text #tag1 #tag2 (context)
+```
+
+| Part | Required | Description |
+|------|----------|-------------|
+| `[category]` | Yes | Classification in square brackets. Any text except `[]()` chars. |
+| content | Yes | The fact or statement. |
+| `#tags` | No | Inline tags. Space-separated, each starting with `#`. |
+| `(context)` | No | Parenthesized text at end of line. Supporting details or source. |
+
+### Examples
+
+```markdown
+- [tech] Uses SQLite for storage #database
+- [design] Follows local-first architecture #architecture
+- [decision] Selected bcrypt for passwords #security (based on OWASP audit)
+- [name] Paul Graham
+- [expertise] Startups
+- [expertise] Lisp
+- [expertise] Essay writing
+```
+
+Array-like fields use repeated categories — multiple `[expertise]` observations above.
+
+### What Is Not an Observation
+
+The parser excludes these list item patterns:
+
+| Pattern | Example | Reason |
+|---------|---------|--------|
+| Checkboxes | `- [ ] Todo item`, `- [x] Done`, `- [-] Cancelled` | Task list syntax |
+| Markdown links | `- [text](url)` | URL link syntax |
+| Bare wiki links | `- [[Target]]` | Treated as a relation instead |
+
+A list item with `#tags` but no `[category]` is still parsed — the tags are extracted and the category defaults to `Note`.
+
+## Relations
+
+Relations connect documents to form the knowledge graph. There are two kinds.
+
+### Explicit Relations
+
+Written as list items with a relation type and a `[[wiki link]]` target.
+
+**Syntax:**
+
+```
+- relation_type [[Target Entity]] (context)
+```
+
+| Part | Required | Description |
+|------|----------|-------------|
+| `relation_type` | No | Text before `[[`. Defaults to `relates_to` if omitted. |
+| `[[Target]]` | Yes | Wiki link to the target entity. Matched by title or permalink. |
+| `(context)` | No | Parenthesized text after `]]`. Supporting details. |
+
+### Examples
+
+```markdown
+- implements [[Search Design]]
+- depends_on [[Database Schema]]
+- works_at [[Y Combinator]] (co-founder)
+- [[Some Entity]]
+```
+
+The last example — a bare `[[wiki link]]` in a list item — gets relation type `relates_to`.
+
+Common relation types:
+- `implements`, `depends_on`, `relates_to`, `inspired_by`
+- `extends`, `part_of`, `contains`, `pairs_with`
+- `works_at`, `authored`, `collaborated_with`
+
+Any text works as a relation type. These are conventions, not a fixed set.
+
+### Inline References
+
+Wiki links appearing in regular prose (not as list items) create implicit `links_to` relations.
+
+```markdown
+This builds on [[Core Design]] and uses [[Utility Functions]].
+```
+
+This creates two relations: `links_to [[Core Design]]` and `links_to [[Utility Functions]]`.
+
+### Forward References
+
+Relations can link to entities that don't exist yet. Basic Memory resolves them when the target is created.
+
+## Permalinks and memory:// URLs
+
+Every document has a unique **permalink** — a stable identifier derived from its title. You can set one explicitly in frontmatter, or let the system generate it.
+
+```yaml
+permalink: auth-approaches-2024
+```
+
+Permalinks form the basis of `memory://` URLs:
+
+```
+memory://auth-approaches-2024        # By permalink
+memory://Authentication Approaches   # By title (auto-resolves)
+memory://project/auth-approaches     # By path
+```
+
+Pattern matching is supported:
+
+```
+memory://auth*                       # Starts with "auth"
+memory://*/approaches                # Ends with "approaches"
+memory://project/*/requirements      # Nested wildcard
+```
+
+## Schemas
+
+Schemas declare the expected structure of a note — which observation categories and relation types a well-formed note should have. They use Picoschema, a compact notation from Google's Dotprompt that fits naturally in YAML frontmatter.
+
+### Picoschema Syntax
+
+```yaml
+schema:
+  name: string, full name              # required field with description
+  email?: string, contact email        # ? = optional
+  role?: string, job title
+  works_at?: Organization, employer    # capitalized type = entity reference
+  tags?(array): string, categories     # array of type
+  status?(enum): [active, inactive]    # enum with allowed values
+  metadata?(object):                   # nested object
+    updated_at?: string
+    source?: string
+```
+
+| Notation | Meaning | Example |
+|----------|---------|---------|
+| `field: type` | Required field | `name: string` |
+| `field?: type` | Optional field | `role?: string` |
+| `field(array): type` | Array of values | `expertise(array): string` |
+| `field?(enum): [vals]` | Enum with allowed values | `status?(enum): [active, inactive]` |
+| `field?(object):` | Nested object with sub-fields | `metadata?(object):` |
+| `, description` | Description after comma | `name: string, full name` |
+| `EntityName` | Capitalized type = entity reference | `works_at?: Organization` |
+
+**Scalar types:** `string`, `integer`, `number`, `boolean`, `any`
+
+Any type not in that set whose first letter is uppercase is treated as an entity reference (a relation target).
+
+### Schema-to-Note Mapping
+
+Schemas validate against existing observation/relation syntax. Note authors don't learn new syntax.
+
+| Schema Declaration | Maps To | Example in Note |
+|--------------------|---------|-----------------|
+| `field: string` | Observation `[field] value` | `- [name] Paul Graham` |
+| `field?(array): string` | Multiple `[field]` observations | `- [expertise] Lisp` (repeated) |
+| `field?: EntityType` | Relation `field [[Target]]` | `- works_at [[Y Combinator]]` |
+| `field?(array): EntityType` | Multiple `field` relations | `- authored [[Book]]` (repeated) |
+| `tags` | Frontmatter `tags` array | `tags: [startups, essays]` |
+| `field?(enum): [vals]` | Observation `[field] value` where value is in the set | `- [status] active` |
+
+Observations and relations not covered by the schema are valid — schemas describe a subset, not a straitjacket.
+
+### Schema Attachment
+
+Three ways to attach a schema to a note, resolved in priority order:
+
+**1. Inline schema** — `schema` is a dict in frontmatter:
+
+```yaml
+---
+title: Team Standup 2024-01-15
+type: meeting
+schema:
+  attendees(array): string, who was there
+  decisions(array): string, what was decided
+  action_items(array): string, follow-ups
+  blockers?(array): string, anything stuck
+---
+```
+
+Good for one-off structured notes or prototyping a schema before extracting it.
+
+**2. Explicit reference** — `schema` is a string naming a schema note:
+
+```yaml
+---
+title: Basic Memory
+schema: SoftwareProject
+---
+```
+
+or by permalink:
+
+```yaml
+---
+title: LLM Memory Patterns
+schema: schema/research-project
+---
+```
+
+Use when the note's `type` differs from the schema it should validate against, or when multiple schema variants exist.
+
+**3. Implicit by type** — no `schema` field, resolved by matching `type`:
+
+```yaml
+---
+title: Paul Graham
+type: Person
+---
+```
+
+The system looks up a schema note where `entity: Person`. If found, it applies. If not, no validation occurs.
+
+**4. No schema** — perfectly fine. Most notes don't need one.
+
+### Schema Notes
+
+A schema is itself a Basic Memory note with `type: schema`. It lives anywhere (though `schema/` is the conventional directory).
+
+```yaml
+# schema/Person.md
+---
+title: Person
+type: schema
+entity: Person
+version: 1
+schema:
+  name: string, full name
+  role?: string, job title or position
+  works_at?: Organization, employer
+  expertise?(array): string, areas of knowledge
+  email?: string, contact email
+settings:
+  validation: warn
+---
+
+# Person
+
+A human individual in the knowledge graph.
+```
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `type` | Yes | Must be `schema` |
+| `entity` | Yes | The entity type this schema describes (e.g., `Person`) |
+| `version` | No | Schema version number (default: `1`) |
+| `schema` | Yes | Picoschema dict defining the fields |
+| `settings.validation` | No | Validation mode (default: `warn`) |
+
+Schema notes are regular notes — they show up in search, can have observations and relations, and participate in the knowledge graph.
+
+### Validation Modes
+
+| Mode | Behavior |
+|------|----------|
+| `warn` | Warnings in output, doesn't block (default) |
+| `strict` | Errors that block sync, for CI/CD enforcement |
+| `off` | No validation |
+
+### Validation Output
+
+```
+$ bm schema validate people/ada-lovelace.md
+
+⚠ Person schema validation:
+  - Missing required field: name (expected [name] observation)
+  - Missing optional field: role
+  - Missing optional field: works_at (no relation found)
+
+ℹ Unmatched observations: [fact] ×2, [born] ×1
+ℹ Unmatched relations: collaborated_with
+```
+
+"Unmatched" items are informational — observations and relations the schema doesn't cover.
+
+### Schema Inference
+
+Generate schemas from existing notes by analyzing observation and relation frequency:
+
+```
+$ bm schema infer Person
+
+Analyzing 30 notes with type: Person...
+
+Observations found:
+  [name]        30/30  100%  → name: string
+  [role]        27/30   90%  → role?: string
+  [expertise]   18/30   60%  → expertise?(array): string
+  [email]        8/30   27%  → email?: string
+
+Relations found:
+  works_at      22/30   73%  → works_at?: Organization
+
+Suggested schema:
+  name: string, full name
+  role?: string, job title
+  expertise?(array): string, areas of knowledge
+  email?: string, contact email
+  works_at?: Organization, employer
+
+Save to schema/Person.md? [y/n]
+```
+
+Frequency thresholds:
+- **100% present** → required field
+- **25%+ present** → optional field
+- **Below 25%** → excluded from suggestion
+
+### Schema Drift Detection
+
+Track how usage patterns shift over time:
+
+```
+$ bm schema diff Person
+
+Schema drift detected:
+
++ expertise: now in 81% of notes (was 12%)
+- department: dropped to 3% of notes
+~ works_at: cardinality changed (one → many)
+
+Update schema? [y/n/review]
+```
+
+## Complete Examples
+
+### Simple Note (No Schema)
+
+```markdown
+---
+title: Project Ideas
+type: note
+tags: [ideas, brainstorm]
+---
+
+# Project Ideas
+
+## Observations
+- [idea] Build a CLI tool for markdown linting #tooling
+- [idea] Create a recipe knowledge base #cooking
+- [priority] Focus on developer tools first (Q1 goal)
+
+## Relations
+- inspired_by [[Developer Workflow Research]]
+- part_of [[Q1 Planning]]
+```
+
+### Schema-Validated Note
+
+Schema at `schema/Person.md`:
+
+```yaml
+---
+title: Person
+type: schema
+entity: Person
+version: 1
+schema:
+  name: string, full name
+  role?: string, job title or position
+  works_at?: Organization, employer
+  expertise?(array): string, areas of knowledge
+  email?: string, contact email
+settings:
+  validation: warn
+---
+
+# Person
+
+A human individual in the knowledge graph.
+```
+
+Note at `people/paul-graham.md`:
+
+```markdown
+---
+title: Paul Graham
+type: Person
+tags: [startups, essays, lisp]
+---
+
+# Paul Graham
+
+## Observations
+- [name] Paul Graham
+- [role] Essayist and investor
+- [expertise] Startups
+- [expertise] Lisp
+- [expertise] Essay writing
+- [fact] Created Viaweb, the first web app
+
+## Relations
+- works_at [[Y Combinator]]
+- authored [[Hackers and Painters]]
+```
+
+The `[fact]` observation and `authored` relation are not in the schema — they're valid, just unmatched. The schema only checks that `[name]` exists (required) and looks for optional fields like `[role]`, `[expertise]`, and `works_at`.
+
+### Inline Schema Note
+
+```markdown
+---
+title: Team Standup 2024-01-15
+type: meeting
+schema:
+  attendees(array): string, who was there
+  decisions(array): string, what was decided

-3. In Claude Desktop, the LLM can now use these tools:
+3. Cloud features (optional, requires subscription):
 
+```bash
+# Authenticate with cloud (stores OAuth token locally)
+basic-memory cloud login
+
+# (Optional) install/configure rclone for file sync commands
+basic-memory cloud setup
+
+# Check cloud auth + health
+basic-memory cloud status
+```
+
+**Per-Project Cloud Routing** (API key based):
+
+Individual projects can be routed through the cloud while others stay local. This uses an API key for routed
+project calls:
+
+```bash
+# Save an API key (create one in the web app or via CLI)
+basic-memory cloud set-key bmc_abc123...
+# Or create one via CLI (requires OAuth login first)
+basic-memory cloud create-key "my-laptop"
+
+# Set a project to route through cloud
+basic-memory project set-cloud research
+
+# Revert a project to local mode
+basic-memory project set-local research
+
+# List projects and route metadata
+basic-memory project list
+```
+
+`basic-memory cloud login` / `basic-memory cloud logout` are authentication commands. They do not change default CLI
+routing behavior.
+
+**Routing Flags**:
+
+Use routing flags to disambiguate command targets:
+
+```bash
+# Force local routing for this command
+basic-memory status --local
+basic-memory project list --local
+basic-memory project ls --name main --local
+
+# Force cloud routing for this command
+basic-memory status --cloud
+basic-memory project info my-project --cloud
+basic-memory project ls --name main --cloud
+```
+
+No-flag behavior defaults to local when no project context is present.
+
+The local MCP server routes per transport: `--transport stdio` honors per-project routing
+(local or cloud), while `--transport streamable-http` and `--transport sse` always route locally.
+
+**CLI Note Editing (`tool edit-note`):**
+
+```bash
+# Append content
+basic-memory tool edit-note project-plan --operation append --content $'\n## Next Steps\n- Finalize rollout'
+
+# Find/replace with replacement count validation
+basic-memory tool edit-note docs/api --operation find_replace --find-text "v0.14.0" --content "v0.15.0" --expected-replacements 2

+
+# JSON metadata output for integrations
+basic-memory tool edit-note docs/setup --operation append --content $'\n- Added note' --format json
+```
+
+4. In Claude Desktop, the LLM can now use these tools:
+
+**Content Management:**
+```
+write_note(title, content, folder, tags, output_format="text"|"json") - Create or update notes
+read_note(identifier, page, page_size, output_format="text"|"json") - Read notes by title or permalink
+read_content(path) - Read raw file content (text, images, binaries)
+view_note(identifier) - View notes as formatted artifacts
+edit_note(identifier, operation, content, output_format="text"|"json") - Edit notes incrementally
+move_note(identifier, destination_path, output_format="text"|"json") - Move notes with database consistency
+delete_note(identifier, output_format="text"|"json") - Delete notes from knowledge base
+```
+
+**Knowledge Graph Navigation:**
+```
+build_context(url, depth, timeframe, output_format="json"|"text") - Navigate knowledge graph via memory:// URLs
+recent_activity(type, depth, timeframe, output_format="text"|"json") - Find recently updated information
+list_directory(dir_name, depth) - Browse directory contents with filtering
+```
+
+**Search & Discovery:**

+
+## Telemetry
+
+Basic Memory collects anonymous, minimal usage events to understand how the CLI-to-cloud conversion funnel performs. This helps us prioritize features and improve the product.
+
+**What we collect:**
+- Cloud promo impressions (when the promo banner is shown)
+- Cloud login attempts and outcomes
+- Promo opt-out events
+
+**What we do NOT collect:**
+- No file contents, note titles, or knowledge base data
+- No personally identifiable information (PII)
+- No IP address tracking or fingerprinting
+- No per-command or per-tool-call tracking
+
+Events are sent to our [Umami Cloud](https://umami.is) instance, an open-source, privacy-focused analytics platform. Events are fire-and-forget on a background thread — analytics never blocks or slows the CLI.
+
+**Opt out** by setting the environment variable:
+
+```bash
+export BASIC_MEMORY_NO_PROMOS=1
+```
+
+This disables both promo messages and all telemetry events.
+
+## Logging
+
+Basic Memory uses [Loguru](https://github.com/Delgan/loguru) for logging. The logging behavior varies by entry point:
+
+| Entry Point | Default Behavior | Use Case |
+|-------------|------------------|----------|
+| CLI commands | File only | Prevents log output from interfering with command output |
+| MCP server | File only | Stdout would corrupt the JSON-RPC protocol |
+| API server | File (local) or stdout (cloud) | Docker/cloud deployments use stdout |
+
+**Log file location:** `~/.basic-memory/basic-memory.log` (10MB rotation, 10 days retention)
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `BASIC_MEMORY_LOG_LEVEL` | `INFO` | Log level: DEBUG, INFO, WARNING, ERROR |
+| `BASIC_MEMORY_CLOUD_MODE` | `false` | When `true`, API logs to stdout with structured context |
+| `BASIC_MEMORY_FORCE_LOCAL` | `false` | When `true`, forces local API routing |
+| `BASIC_MEMORY_FORCE_CLOUD` | `false` | When `true`, forces cloud API routing |
+| `BASIC_MEMORY_EXPLICIT_ROUTING` | `false` | When `true`, marks route selection as explicit (`--local`/`--cloud`) |
+| `BASIC_MEMORY_ENV` | `dev` | Set to `test` for test mode (stderr only) |
+| `BASIC_MEMORY_NO_PROMOS` | `false` | When `true`, disables cloud promo messages and telemetry |
+
+### Examples
+
+```bash
+# Enable debug logging
+BASIC_MEMORY_LOG_LEVEL=DEBUG basic-memory sync
+
+# View logs
+tail -f ~/.basic-memory/basic-memory.log
+
+# Cloud/Docker mode (stdout logging with structured context)
+BASIC_MEMORY_CLOUD_MODE=true uvicorn basic_memory.api.app:app
+```
+
+## Development
+
+### Running Tests
+
+Basic Memory supports dual database backends (SQLite and Postgres). By default, tests run against SQLite. Set `BASIC_MEMORY_TEST_POSTGRES=1` to run against Postgres (uses testcontainers - Docker required).
+
+**Quick Start:**
+```bash
+# Run all tests against SQLite (default, fast)
+just test-sqlite
+
+# Run all tests against Postgres (uses testcontainers)
+just test-postgres
+
+# Run both SQLite and Postgres tests
+just test
+```
+
+**Available Test Commands:**
+
+- `just test` - Run all tests against both SQLite and Postgres
+- `just test-sqlite` - Run all tests against SQLite (fast, no Docker needed)
+- `just test-postgres` - Run all tests against Postgres (uses testcontainers)
+- `just test-unit-sqlite` - Run unit tests against SQLite
+- `just test-unit-postgres` - Run unit tests against Postgres
+- `just test-int-sqlite` - Run integration tests against SQLite
+- `just test-int-postgres` - Run integration tests against Postgres
+- `just test-windows` - Run Windows-specific tests (auto-skips on other platforms)
+- `just test-benchmark` - Run performance benchmark tests
+- `just testmon` - Run tests impacted by recent changes (pytest-testmon)
+- `just test-smoke` - Run fast MCP end-to-end smoke test
+- `just fast-check` - Run fix/format/typecheck + impacted tests + smoke test
+- `just doctor` - Run local file <-> DB consistency checks with temp config
+
+**Postgres Testing:**
+
+Postgres tests use [testcontainers](https://testcontainers-python.readthedocs.io/) which automatically spins up a Postgres instance in Docker. No manual database setup required - just have Docker running.
+
+**Testmon Note:** When no files have changed, `just testmon` may collect 0 tests. That's expected and means no impacted tests were detected.
+
+**Test Markers:**
+
+Tests use pytest markers for selective execution:
+- `windows` - Windows-specific database optimizations
+- `benchmark` - Performance tests (excluded from default runs)
+- `smoke` - Fast MCP end-to-end smoke tests
+
+**Other Development Commands:**
+```bash
+just install          # Install with dev dependencies
+just lint             # Run linting checks
+just typecheck        # Run type checking
+just typecheck-ty     # Run ty type checking (incremental supplement to pyright)
+just format           # Format code with ruff
+just fast-check       # Fast local loop (fix/format/typecheck + testmon + smoke)
+just doctor           # Local consistency check (temp config)
+just check            # Run all quality checks
+just migration "msg"  # Create database migration
+```
+
+**Type Checking Strategy:**
+- `just typecheck` (Pyright) remains the primary, blocking type checker.
+- `just typecheck-ty` (Astral `ty`) is available as a supplemental checker while rules are adopted incrementally.
+- We recommend running both locally while reducing `ty` diagnostics over time.
+
+**Local Consistency Check:**
+```bash
+basic-memory doctor   # Verifies file <-> database sync in a temp project
+```
+
+See the [justfile](justfile) for the complete list of development commands.

+# Basic Memory Architecture
+
+This document describes the architectural patterns and composition structure of Basic Memory.
+
+## Overview
+
+Basic Memory is a local-first knowledge management system with three entrypoints:
+- **API** - FastAPI REST server for HTTP access
+- **MCP** - Model Context Protocol server for LLM integration
+- **CLI** - Typer command-line interface
+
+Each entrypoint uses a **composition root** pattern to manage configuration and dependencies.
+
+## Composition Roots
+
+### What is a Composition Root?
+
+A composition root is the single place in an application where dependencies are wired together. In Basic Memory, each entrypoint has its own composition root that:
+
+1. Reads configuration from `ConfigManager`
+2. Resolves runtime mode (local/test)
+3. Creates and provides dependencies to downstream code
+
+**Key principle**: Only composition roots read global configuration. All other modules receive configuration explicitly.
+
+### Container Structure
+
+Each entrypoint has a container dataclass in its package:
+
+```
+src/basic_memory/
+├── api/
+│   └── container.py      # ApiContainer
+├── mcp/
+│   └── container.py      # McpContainer
+├── cli/
+│   └── container.py      # CliContainer
+└── runtime.py            # RuntimeMode enum and resolver
+```
+
+### Container Pattern
+
+All containers follow the same structure:
+
+```python
+@dataclass
+class Container:
+    config: BasicMemoryConfig
+    mode: RuntimeMode
+
+    @classmethod
+    def create(cls) -> "Container":
+        """Create container by reading ConfigManager."""
+        config = ConfigManager().config
+        mode = resolve_runtime_mode(is_test_env=config.is_test_env)
+        return cls(config=config, mode=mode)
+
+    @property
+    def some_computed_property(self) -> bool:
+        """Derived values based on config and mode."""
+        return self.mode.is_local and self.config.some_setting
+
+# Module-level singleton
+_container: Container | None = None
+
+def get_container() -> Container:
+    if _container is None:
+        raise RuntimeError("Container not initialized")
+    return _container
+
+def set_container(container: Container) -> None:
+    global _container
+    _container = container
+```
+
+### Runtime Mode Resolution
+
+The `RuntimeMode` enum centralizes mode detection:
+
+```python
+class RuntimeMode(Enum):
+    LOCAL = "local"
+    CLOUD = "cloud"
+    TEST = "test"
+
+    @property
+    def is_cloud(self) -> bool:
+        return self == RuntimeMode.CLOUD
+
+    @property
+    def is_local(self) -> bool:
+        return self == RuntimeMode.LOCAL
+
+    @property
+    def is_test(self) -> bool:
+        return self == RuntimeMode.TEST
+```
+
+Resolution follows this precedence in local app flows: **TEST > LOCAL**
+
+```python
+def resolve_runtime_mode(is_test_env: bool) -> RuntimeMode:
+    if is_test_env:
+        return RuntimeMode.TEST
+    return RuntimeMode.LOCAL
+```
+
+**Note**: `RuntimeMode` determines global behavior (e.g., whether to start file sync).
+Per-project routing is orthogonal: individual projects can be set to `cloud` mode via `ProjectMode`,
+which affects client routing in `get_client(project_name=...)` without changing global runtime mode.
+`RuntimeMode.CLOUD` may remain for compatibility, but standard local runtime resolution does not select it.
+
+## Dependencies Package
+
+### Structure
+
+The `deps/` package provides FastAPI dependencies organized by feature:
+
+```
+src/basic_memory/deps/
+├── __init__.py       # Re-exports for backwards compatibility
+├── config.py         # Configuration access
+├── db.py             # Database/session management
+├── projects.py       # Project resolution
+├── repositories.py   # Data access layer
+├── services.py       # Business logic layer
+└── importers.py      # Import functionality
+```
+
+### Usage in Routers
+
+```python
+from basic_memory.deps.services import get_entity_service
+from basic_memory.deps.projects import get_project_config
+
+@router.get("/entities/{id}")
+async def get_entity(
+    id: int,
+    entity_service: EntityService = Depends(get_entity_service),
+    project: ProjectConfig = Depends(get_project_config),
+):
+    return await entity_service.get(id)
+```
+
+### Backwards Compatibility
+
+The old `deps.py` file still exists as a thin re-export shim:
+
+```python
+# deps.py - backwards compatibility shim
+from basic_memory.deps import *
+```
+
+New code should import from specific submodules (`basic_memory.deps.services`) for clarity.
+
+## MCP Tools Architecture
+
+### Typed API Clients
+
+MCP tools communicate with the API through typed clients that encapsulate HTTP paths and response validation:
+
+```
+src/basic_memory/mcp/clients/
+├── __init__.py       # Re-exports all clients
+├── base.py           # BaseClient with common logic
+├── knowledge.py      # KnowledgeClient - entity CRUD
+├── search.py         # SearchClient - search operations
+├── memory.py         # MemoryClient - context building
+├── directory.py      # DirectoryClient - directory listing
+├── resource.py       # ResourceClient - resource reading
+└── project.py        # ProjectClient - project management
+```
+
+### Client Pattern
+
+Each client encapsulates API paths and validates responses:
+
+```python
+class KnowledgeClient(BaseClient):
+    """Client for knowledge/entity operations."""
+
+    async def resolve_entity(self, identifier: str) -> int:
+        """Resolve identifier to entity ID."""
+        response = await call_get(
+            self.http_client,
+            f"{self._base_path}/resolve/{identifier}",
+        )
+        return int(response.text)
+
+    async def get_entity(self, entity_id: int) -> EntityResponse:
+        """Get entity by ID."""
+        response = await call_get(
+            self.http_client,
+            f"{self._base_path}/entities/{entity_id}",
+        )
+        return EntityResponse.model_validate(response.json())
+```
+
+### Tool → Client → API Flow
+
+```
+MCP Tool (thin adapter)
+    ↓
+Typed Client (encapsulates paths, validates responses)
+    ↓
+HTTP API (FastAPI router)
+    ↓
+Service Layer (business logic)
+    ↓
+Repository Layer (data access)
+```
+
+Example tool using typed client:
+
+```python
+@mcp.tool()
+async def search_notes(
+    query: str,
+    project: str | None = None,
+    metadata_filters: dict | None = None,
+    tags: list[str] | None = None,
+    status: str | None = None,
+) -> SearchResponse:
+    async with get_project_client(project, context) as (client, active_project):
+        # Import client inside function to avoid circular imports
+        from basic_memory.mcp.clients import SearchClient
+        from basic_memory.schemas.search import SearchQuery
+
+        search_query = SearchQuery(
+            text=query,
+            metadata_filters=metadata_filters,
+            tags=tags,
+            status=status,
+        )
+        search_client = SearchClient(client, active_project.external_id)
+        return await search_client.search(search_query.model_dump())
+```
+
+### Per-Project Client Routing
+
+`get_project_client()` from `mcp/project_context.py` is an async context manager that:
+1. Resolves the project name from config (no network call)
+2. Creates the correctly-routed client based on the project's mode (local ASGI or cloud HTTP with API key)
+3. Validates the project via the API
+4. Yields `(client, active_project)` tuple
+
+This solves the bootstrap problem: you need the project name to choose the right client (local vs cloud), but you need the client to validate the project exists.
+
+```python
+from basic_memory.mcp.project_context import get_project_client
+
+async with get_project_client(project, context) as (client, active_project):
+    # client is routed based on project's mode (local or cloud)
+    # active_project is validated via the API
+    ...
+```
+
+## Sync Coordination
+
+### SyncCoordinator
+
+The `SyncCoordinator` centralizes sync/watch lifecycle management:
+
+```python
+@dataclass
+class SyncCoordinator:
+    """Coordinates file sync and watch operations."""
+
+    status: SyncStatus = SyncStatus.NOT_STARTED
+    sync_task: asyncio.Task | None = None
+    watch_service: WatchService | None = None
+
+    async def start(self, ...):
+        """Start sync and watch operations."""
+
+    async def stop(self):
+        """Stop all sync operations gracefully."""
+
+    def get_status_info(self) -> dict:
+        """Get current sync status for observability."""
+```
+
+### Status Enum
+
+```python
+class SyncStatus(Enum):
+    NOT_STARTED = "not_started"
+    STARTING = "starting"
+    RUNNING = "running"
+    STOPPING = "stopping"
+    STOPPED = "stopped"
+    ERROR = "error"
+```
+
+## Project Resolution
+
+### ProjectResolver
+
+Unified project selection across all entrypoints:
+
+```python
+class ProjectResolver:
+    """Resolves which project to use based on context."""
+
+    def resolve(
+        self,
+        explicit_project: str | None = None,
+    ) -> ResolvedProject:
+        """Resolve project using three-tier hierarchy:
+        1. Explicit project parameter
+        2. Default project from config
+        3. Single available project
+        """
+```
+
+### Resolution Modes
+
+```python
+class ResolutionMode(Enum):
+    EXPLICIT = "explicit"           # User specified project
+    DEFAULT = "default"             # Using configured default
+    SINGLE_PROJECT = "single"       # Only one project exists
+    FALLBACK = "fallback"           # Using first available
+```
+
+## Testing Patterns
+
+### Container Testing
+
+Each container has corresponding tests:
+
+```
+tests/
+├── api/test_api_container.py
+├── mcp/test_mcp_container.py
+└── cli/test_cli_container.py
+```
+
+Tests verify:
+- Container creation from config
+- Runtime mode properties
+- Container accessor functions (get/set)
+
+### Mocking Typed Clients
+
+When testing MCP tools, mock at the client level:
+
+```python
+def test_search_notes(monkeypatch):
+    import basic_memory.mcp.clients as clients_mod
+
+    class MockSearchClient:
+        async def search(self, query):
+            return SearchResponse(results=[...])
+
+    monkeypatch.setattr(clients_mod, "SearchClient", MockSearchClient)
+```
+
+## Design Principles
+
+### 1. Explicit Dependencies
+
+Modules receive configuration explicitly rather than reading globals:
+
+```python
+# Good - explicit injection
+async def sync_files(config: BasicMemoryConfig):
+    ...
+
+# Avoid - hidden global access
+async def sync_files():
+    config = ConfigManager().config  # Hidden coupling
+```
+
+### 2. Single Responsibility
+
+Each layer has a clear responsibility:
+- **Containers**: Wire dependencies
+- **Clients**: Encapsulate HTTP communication
+- **Services**: Business logic
+- **Repositories**: Data access
+- **Tools/Routers**: Thin adapters
+
+### 3. Deferred Imports
+
+To avoid circular imports, typed clients are imported inside functions:
+
+```python
+async def my_tool():
+    async with get_client() as client:
+        # Import here to avoid circular dependency
+        from basic_memory.mcp.clients import KnowledgeClient
+
+        knowledge_client = KnowledgeClient(client, project_id)
+```
+
+### 4. Backwards Compatibility
+
+When refactoring, maintain backwards compatibility via shims:
+
+```python
+# Old module becomes a shim
+from basic_memory.new_location import *
+
+# Docstring explains migration path
+"""
+DEPRECATED: Import from basic_memory.new_location instead.
+This shim will be removed in a future version.
+"""
+```

+# Note Format Reference
+
+Every document in Basic Memory is a plain Markdown file. Files are the source of truth — changes to files automatically update the knowledge graph in the database. You maintain complete ownership, files work with git, and knowledge persists independently of any AI conversation.
+
+## Document Structure
+
+A note has three parts: YAML frontmatter, content (observations), and relations.
+
+```markdown
+---
+title: Coffee Brewing Methods
+type: note
+tags: [coffee, brewing]
+permalink: coffee-brewing-methods
+---
+
+# Coffee Brewing Methods
+
+## Observations
+- [method] Pour over provides more flavor clarity than French press
+- [technique] Water temperature at 205°F extracts optimal compounds #brewing
+- [preference] Ethiopian beans work well with lighter roasts (personal experience)
+
+## Relations
+- relates_to [[Coffee Bean Origins]]
+- requires [[Proper Grinding Technique]]
+- contrasts_with [[Tea Brewing Methods]]
+```
+
+The `## Observations` and `## Relations` headings are conventional but not required — the parser detects observations and relations by their syntax patterns anywhere in the document.
+
+## Frontmatter
+
+YAML metadata between `---` fences at the top of the file.
+
+| Field | Required | Default | Description |
+|-------|----------|---------|-------------|
+| `title` | No | filename stem | Used for linking and references. Auto-set from filename if missing. |
+| `type` | No | `note` | Entity type. Used for schema resolution and filtering. |
+| `tags` | No | `[]` | List or comma-separated string. Used for organization and search. |
+| `permalink` | No | generated from title | Stable identifier. Persists even if the file moves. |
+| `schema` | No | none | Schema attachment — dict (inline), string (reference), or omitted (implicit). |
+
+Custom fields are allowed. Any key not in the standard set is stored as `entity_metadata` and indexed for search and filtering.
+
+```yaml
+---
+title: Paul Graham
+type: Person
+tags: [startups, essays, lisp]
+permalink: paul-graham
+status: active
+source: wikipedia
+---
+```
+
+Here `status` and `source` are custom fields stored in `entity_metadata`.
+
+### Frontmatter Value Handling
+
+YAML automatically converts some values to native types. Basic Memory normalizes them:
+
+- Date strings (`2025-10-24`) → kept as ISO format strings
+- Numbers (`1.0`) → converted to strings
+- Booleans (`true`) → converted to strings (`"True"`)
+- Lists and dicts → preserved, items normalized recursively
+
+This prevents errors when downstream code expects string values.
+
+## Observations
+
+An observation is a categorized fact about the entity. Written as a Markdown list item.
+
+**Syntax:**
+
+```
+- [category] content text #tag1 #tag2 (context)
+```
+
+| Part | Required | Description |
+|------|----------|-------------|
+| `[category]` | Yes | Classification in square brackets. Any text except `[]()` chars. |
+| content | Yes | The fact or statement. |
+| `#tags` | No | Inline tags. Space-separated, each starting with `#`. |
+| `(context)` | No | Parenthesized text at end of line. Supporting details or source. |
+
+### Examples
+
+```markdown
+- [tech] Uses SQLite for storage #database
+- [design] Follows local-first architecture #architecture
+- [decision] Selected bcrypt for passwords #security (based on OWASP audit)
+- [name] Paul Graham
+- [expertise] Startups
+- [expertise] Lisp
+- [expertise] Essay writing
+```
+
+Array-like fields use repeated categories — multiple `[expertise]` observations above.
+
+### What Is Not an Observation
+
+The parser excludes these list item patterns:
+
+| Pattern | Example | Reason |
+|---------|---------|--------|
+| Checkboxes | `- [ ] Todo item`, `- [x] Done`, `- [-] Cancelled` | Task list syntax |
+| Markdown links | `- [text](url)` | URL link syntax |
+| Bare wiki links | `- [[Target]]` | Treated as a relation instead |
+
+A list item with `#tags` but no `[category]` is still parsed — the tags are extracted and the category defaults to `Note`.
+
+## Relations
+
+Relations connect documents to form the knowledge graph. There are two kinds.
+
+### Explicit Relations
+
+Written as list items with a relation type and a `[[wiki link]]` target.
+
+**Syntax:**
+
+```
+- relation_type [[Target Entity]] (context)
+```
+
+| Part | Required | Description |
+|------|----------|-------------|
+| `relation_type` | No | Text before `[[`. Defaults to `relates_to` if omitted. |
+| `[[Target]]` | Yes | Wiki link to the target entity. Matched by title or permalink. |
+| `(context)` | No | Parenthesized text after `]]`. Supporting details. |
+
+### Examples
+
+```markdown
+- implements [[Search Design]]
+- depends_on [[Database Schema]]
+- works_at [[Y Combinator]] (co-founder)
+- [[Some Entity]]
+```
+
+The last example — a bare `[[wiki link]]` in a list item — gets relation type `relates_to`.
+
+Common relation types:
+- `implements`, `depends_on`, `relates_to`, `inspired_by`
+- `extends`, `part_of`, `contains`, `pairs_with`
+- `works_at`, `authored`, `collaborated_with`
+
+Any text works as a relation type. These are conventions, not a fixed set.
+
+### Inline References
+
+Wiki links appearing in regular prose (not as list items) create implicit `links_to` relations.
+
+```markdown
+This builds on [[Core Design]] and uses [[Utility Functions]].
+```
+
+This creates two relations: `links_to [[Core Design]]` and `links_to [[Utility Functions]]`.
+
+### Forward References
+
+Relations can link to entities that don't exist yet. Basic Memory resolves them when the target is created.
+
+## Permalinks and memory:// URLs
+
+Every document has a unique **permalink** — a stable identifier derived from its title. You can set one explicitly in frontmatter, or let the system generate it.
+
+```yaml
+permalink: auth-approaches-2024
+```
+
+Permalinks form the basis of `memory://` URLs:
+
+```
+memory://auth-approaches-2024        # By permalink
+memory://Authentication Approaches   # By title (auto-resolves)
+memory://project/auth-approaches     # By path
+```
+
+Pattern matching is supported:
+
+```
+memory://auth*                       # Starts with "auth"
+memory://*/approaches                # Ends with "approaches"
+memory://project/*/requirements      # Nested wildcard
+```
+
+## Schemas
+
+Schemas declare the expected structure of a note — which observation categories and relation types a well-formed note should have. They use Picoschema, a compact notation from Google's Dotprompt that fits naturally in YAML frontmatter.
+
+### Picoschema Syntax
+
+```yaml
+schema:
+  name: string, full name              # required field with description
+  email?: string, contact email        # ? = optional
+  role?: string, job title
+  works_at?: Organization, employer    # capitalized type = entity reference
+  tags?(array): string, categories     # array of type
+  status?(enum): [active, inactive]    # enum with allowed values
+  metadata?(object):                   # nested object
+    updated_at?: string
+    source?: string
+```
+
+| Notation | Meaning | Example |
+|----------|---------|---------|
+| `field: type` | Required field | `name: string` |
+| `field?: type` | Optional field | `role?: string` |
+| `field(array): type` | Array of values | `expertise(array): string` |
+| `field?(enum): [vals]` | Enum with allowed values | `status?(enum): [active, inactive]` |
+| `field?(object):` | Nested object with sub-fields | `metadata?(object):` |
+| `, description` | Description after comma | `name: string, full name` |
+| `EntityName` | Capitalized type = entity reference | `works_at?: Organization` |
+
+**Scalar types:** `string`, `integer`, `number`, `boolean`, `any`
+
+Any type not in that set whose first letter is uppercase is treated as an entity reference (a relation target).
+
+### Schema-to-Note Mapping
+
+Schemas validate against existing observation/relation syntax. Note authors don't learn new syntax.
+
+| Schema Declaration | Maps To | Example in Note |
+|--------------------|---------|-----------------|
+| `field: string` | Observation `[field] value` | `- [name] Paul Graham` |
+| `field?(array): string` | Multiple `[field]` observations | `- [expertise] Lisp` (repeated) |
+| `field?: EntityType` | Relation `field [[Target]]` | `- works_at [[Y Combinator]]` |
+| `field?(array): EntityType` | Multiple `field` relations | `- authored [[Book]]` (repeated) |
+| `tags` | Frontmatter `tags` array | `tags: [startups, essays]` |
+| `field?(enum): [vals]` | Observation `[field] value` where value is in the set | `- [status] active` |
+
+Observations and relations not covered by the schema are valid — schemas describe a subset, not a straitjacket.
+
+### Schema Attachment
+
+Three ways to attach a schema to a note, resolved in priority order:
+
+**1. Inline schema** — `schema` is a dict in frontmatter:
+
+```yaml
+---
+title: Team Standup 2024-01-15
+type: meeting
+schema:
+  attendees(array): string, who was there
+  decisions(array): string, what was decided
+  action_items(array): string, follow-ups
+  blockers?(array): string, anything stuck
+---
+```
+
+Good for one-off structured notes or prototyping a schema before extracting it.
+
+**2. Explicit reference** — `schema` is a string naming a schema note:
+
+```yaml
+---
+title: Basic Memory
+schema: SoftwareProject
+---
+```
+
+or by permalink:
+
+```yaml
+---
+title: LLM Memory Patterns
+schema: schema/research-project
+---
+```
+
+Use when the note's `type` differs from the schema it should validate against, or when multiple schema variants exist.
+
+**3. Implicit by type** — no `schema` field, resolved by matching `type`:
+
+```yaml
+---
+title: Paul Graham
+type: Person
+---
+```
+
+The system looks up a schema note where `entity: Person`. If found, it applies. If not, no validation occurs.
+
+**4. No schema** — perfectly fine. Most notes don't need one.
+
+### Schema Notes
+
+A schema is itself a Basic Memory note with `type: schema`. It lives anywhere (though `schema/` is the conventional directory).
+
+```yaml

+```
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `type` | Yes | Must be `schema` |
+| `entity` | Yes | The entity type this schema describes (e.g., `Person`) |
+| `version` | No | Schema version number (default: `1`) |
+| `schema` | Yes | Picoschema dict defining the fields |
+| `settings.validation` | No | Validation mode (default: `warn`) |
+
+Schema notes are regular notes — they show up in search, can have observations and relations, and participate in the knowledge graph.

+# Simplified Local/Cloud Routing
+
+## Context
+
+Basic Memory now uses explicit, project-aware routing without a global cloud-mode toggle.
+Routing is determined by command-level flags and project mode, not by a global `cloud_mode` state.
+
+This document is the canonical contract for local/cloud routing behavior in CLI, MCP, and API-adjacent clients.
+
+## Goals
+
+1. Remove global `cloud_mode` from runtime/routing semantics.
+2. Keep MCP HTTP/SSE local-only; let stdio honor per-project routing.
+3. Make CLI routing explicit and easy to reason about.
+4. Support projects that exist in both local and cloud without ambiguity.
+
+## Routing Contract
+
+Routing is resolved in this order:
+
+1. Injected client factory (for composition/integration contexts)
+2. Explicit routing override (`--local` / `--cloud` or env vars below)
+3. Project-scoped routing (`project.mode`) when a project is known
+4. Default local routing
+
+### Routing Environment Variables
+
+- `BASIC_MEMORY_FORCE_LOCAL=true`: force local transport
+- `BASIC_MEMORY_FORCE_CLOUD=true`: force cloud proxy transport
+- `BASIC_MEMORY_EXPLICIT_ROUTING=true`: marks routing as explicitly chosen for this command
+
+When explicit routing is active, project mode does not override the selected route.
+
+## Config Semantics
+
+- `project.mode` is the only config-based routing signal for project-scoped operations.
+- Legacy `cloud_mode` values may be encountered during migration/loading but are not used for routing behavior.
+- Normalization saves remove stale `cloud_mode` from `~/.basic-memory/config.json`.
+
+### Example Config
+
+```json
+{
+  "projects": {
+    "main": {
+      "path": "/Users/me/basic-memory",
+      "mode": "local",
+      "local_sync_path": null,
+      "bisync_initialized": false,
+      "last_sync": null
+    },
+    "specs": {
+      "path": "specs",
+      "mode": "cloud",
+      "local_sync_path": "/Users/me/dev/specs",
+      "bisync_initialized": true,
+      "last_sync": "2026-02-06T17:36:38.544153"
+    }
+  },
+  "default_project": "main",
+  "cloud_api_key": "bmc_abc123...",
+  "cloud_host": "https://cloud.basicmemory.com"
+}
+```
+
+## Cloud Commands Are Auth-Only
+
+`bm cloud login`, `bm cloud logout`, and `bm cloud status` manage authentication state.
+
+- `bm cloud login`
+  - performs OAuth device flow
+  - stores/refreshes token material
+  - may verify cloud health/subscription
+  - does not change routing defaults
+- `bm cloud logout`
+  - removes stored OAuth session tokens
+  - does not change routing defaults
+- `bm cloud status`
+  - reports auth state (API key, OAuth token validity)
+  - runs health checks only when credentials are available
+
+## MCP Transport Routing
+
+### Stdio (default)
+
+`bm mcp --transport stdio` uses natural per-project routing.
+
+- Local-mode projects route through the in-process ASGI transport.
+- Cloud-mode projects route to the cloud proxy with Bearer auth (API key).
+- No explicit routing env vars are injected by the CLI command.
+- Externally-set env vars are honored (e.g. `BASIC_MEMORY_FORCE_CLOUD=true` for cloud deployments).
+- Users who need all projects forced local can set `BASIC_MEMORY_FORCE_LOCAL=true` externally.
+
+### HTTP and SSE Transports
+
+`bm mcp --transport streamable-http` and `bm mcp --transport sse` always route locally.
+
+These transports set explicit local routing (`BASIC_MEMORY_FORCE_LOCAL=true` and
+`BASIC_MEMORY_EXPLICIT_ROUTING=true`) before starting the server. This prevents cloud
+routing regardless of project mode, since HTTP/SSE serve as local API endpoints.
+
+## Project List UX for Dual Presence
+
+Projects may exist in both local and cloud. `bm project list` should display that clearly in one row per logical
+project identity, with explicit source/target signals.
+
+Recommended display contract:
+
+1. Keep one row per normalized project name/permalink.
+2. Show both local and cloud presence as separate columns/indicators.
+3. Show an explicit `MCP (stdio)` target column that always resolves to `local`.
+4. Keep CLI route semantics explicit:
+   - no flags: default local for non-project commands
+   - `--cloud`: force cloud
+   - `--local`: force local
+
+## Project LS Targeting
+
+`bm project ls` should clearly identify which project instance is being listed.
+
+Targeting rules:
+
+1. No routing flags: list local project files.
+2. `--cloud`: list cloud project files.
+3. `--local`: list local project files (explicit override).
+4. Output should label the active target (`LOCAL` or `CLOUD`) in heading or status line.
+
+## Runtime Mode
+
+Runtime mode is no longer a cloud/local routing switch for local app flows.
+
+- `resolve_runtime_mode(is_test_env)` resolves to:
+  - `TEST` when running in test environment
+  - `LOCAL` otherwise
+- `RuntimeMode.CLOUD` may remain for compatibility with existing tests/call sites but is not selected by normal local
+  runtime resolution.
+
+## Verification Checklist
+
+1. Loading config with legacy `cloud_mode` succeeds.
+2. Saving config strips legacy `cloud_mode`.
+3. `--local/--cloud` always override per-project mode for that command.
+4. No-project + no-flags commands route local by default.
+5. `bm cloud login/logout` do not toggle routing behavior.
+6. `bm mcp` stdio routes per-project mode; HTTP/SSE remain local-forced.
+7. `bm project list` communicates dual local/cloud presence without ambiguity.
+8. `bm project ls` output identifies route target explicitly.

+# Cloud Semantic Search Value (Customer-Facing Technical Story)
+
+This document explains why teams should buy cloud semantic search even when local search exists.
+
+## Core Promise
+
+Markdown files remain the source of truth in both local and cloud modes.
+
+- Files are portable.
+- Search indexes are derived and rebuildable.
+- You never get locked into proprietary document storage.
+
+## The Customer Problem
+
+Teams paying for cloud are usually not optimizing for "can this run locally." They are optimizing for:
+
+- finding the right note the first time,
+- keeping retrieval quality high as note volume grows,
+- avoiding search slowdowns while content is actively changing,
+- getting consistent results across users, agents, and sessions.
+
+## Why Cloud Is the Aspirin
+
+Cloud semantic search is the immediate pain reliever because it fixes the problems users feel right now.
+
+### 1) Better hit rate on real queries
+
+Cloud uses stronger managed embeddings than the default local model, which improves semantic recall for paraphrases and vague questions.
+
+Customer outcome:
+
+- fewer "I know this exists but search missed it" moments,
+- less query rewording,
+- faster time to answer.
+
+### 2) Better behavior under active workloads
+
+Cloud indexing runs out of band in workers, so indexing does not compete with interactive read/write traffic.
+
+Customer outcome:
+
+- stable search responsiveness during heavy updates,
+- fresher semantic results shortly after edits,
+- less user-visible performance variance.
+
+### 3) Better consistency for shared knowledge
+
+Cloud retrieval runs against a centralized tenant index, so teams and agents resolve against the same semantic state.
+
+Customer outcome:
+
+- fewer "works on my machine" search differences,
+- more predictable agent behavior across environments,
+- easier cross-user collaboration on large knowledge bases.
+
+### 4) Better quality at higher scale
+
+With Postgres + `pgvector` per tenant, cloud can sustain larger note collections and higher query volumes than typical local setups.
+
+Customer outcome:
+
+- confidence as repositories grow to tens of thousands of notes,
+- less need for user-side tuning,
+- fewer quality regressions as usage increases.
+
+## Local Is the Vitamin
+
+Local semantic search still matters and should stay strong.
+
+- offline use,
+- privacy-first operation,
+- no cloud dependency,
+- user-controlled runtime.
+
+It compounds long-term ownership and resilience, but does not remove the immediate pain points cloud solves for teams at scale.
+
+## Recommended Messaging
+
+One-liner:
+
+"Cloud semantic search is the aspirin: it fixes retrieval quality and performance pain now. Local semantic search is the vitamin: it builds long-term control and resilience."
+
+Long form:
+
+"Basic Memory keeps markdown as the source of truth everywhere. Local gives privacy and offline control. Cloud adds immediate, measurable improvements in search quality, consistency, and responsiveness for teams and agents running at scale."
+
+## Packaging Guidance
+
+- Base: local FTS plus optional local semantic search.
+- Cloud value: higher semantic quality, stable performance under load, and consistent team-wide retrieval.
+- Keep interfaces pluggable (`EmbeddingProvider`, vector backend protocol) so implementation can evolve without changing user workflows.

+# Logfire Instrumentation Strategy
+
+## Why
+
+We want Logfire in Basic Memory for two specific use cases:
+
+1. Local development and performance investigation
+2. Cloud deployments where Basic Memory runs inside Basic Memory Cloud
+
+This instrumentation must be:
+
+- Disabled by default
+- Useful when enabled
+- Safe for local-first users
+- Searchable in Logfire over time
+
+The previous integration added telemetry, but it leaned too much on generic framework instrumentation. That created noisy spans with weak names and made the trace view harder to navigate. This strategy favors manual instrumentation around Basic Memory's real units of work.
+
+## Core Principles
+
+### 1. Default-off
+
+Basic Memory should ship with Logfire disabled unless the operator explicitly enables it.
+
+That means:
+
+- no required token for normal local usage
+- no surprise outbound telemetry
+- no behavior change for existing users
+
+### 2. Manual spans over automatic framework spans
+
+We should not rely on broad auto-instrumentation for FastAPI, MCP, SQLAlchemy, or HTTP as the primary experience.
+
+Why:
+
+- auto-generated span names are often generic
+- routes and middleware produce too many low-signal spans
+- it becomes harder to answer product questions like "why was `write_note` slow?" or "where did sync time go?"
+
+The preferred model is:
+
+- one meaningful root span per high-level operation
+- a small number of child spans for important phases
+- optional targeted instrumentation only where it adds clear value
+
+### 3. Logs must live inside traces
+
+Basic Memory already uses `loguru` pervasively. The Logfire integration should preserve that and make those logs visible inside the active trace/span context.
+
+If traces exist but the logs are detached from them, the integration is not doing its job.
+
+### 4. Stable names, selective attributes
+
+Span names should describe the operation class, not the specific input.
+
+Good:
+
+- `mcp.tool.write_note`
+- `sync.project.scan`
+- `search.execute`
+- `routing.resolve_project`
+
+Bad:
+
+- `Searching for "foo bar baz"`
+- `POST /v2/projects/123/search/`
+- `write note to /specs/api.md`
+
+Dynamic values belong in attributes, not in the span name.
+
+## What We Should Not Do
+
+### Avoid broad FastAPI auto-instrumentation
+
+We should not turn on `instrument_fastapi()` and treat that as the main telemetry story.
+
+It may still be useful in narrowly scoped debugging, but it should not define the production trace shape. The meaningful root spans should come from Basic Memory's own entrypoints and service boundaries.
+
+### Avoid per-file spans by default
+
+`sync` can process many files. A span per file will explode trace cardinality and make performance views noisy.
+
+Default behavior should be:
+
+- one span for the project sync
+- child spans for scan, move handling, delete handling, markdown sync batch, relation resolution, embedding sync, watermark update
+- per-file spans only for failures or very slow outliers
+
+### Avoid high-cardinality attributes on every span
+
+Do not attach large or highly variable values everywhere:
+
+- raw note content
+- file bodies
+- long search text
+- arbitrary metadata blobs
+- unique IDs that make every span shape distinct
+
+Prefer compact, queryable attributes:
+
+- `project_name`
+- `workspace_id`
+- `route_mode`
+- `scan_type`
+- `file_count`
+- `result_count`
+- `search_type`
+- `retrieval_mode`
+- `duration_ms`
+
+## Proposed Architecture
+
+Add a dedicated telemetry module in core Basic Memory, separate from logging setup.
+
+Suggested shape:
+
+```python
+# basic_memory/telemetry.py
+
+def configure_telemetry(service_name: str, *, enable_logfire: bool) -> None: ...
+def telemetry_enabled() -> bool: ...
+def span(name: str, **attrs): ...
+def bind_telemetry_context(**attrs): ...
+```
+
+This module should:
+
+- configure Logfire only when explicitly enabled
+- set up the Logfire `loguru` handler
+- expose lightweight helpers so application code does not import `logfire` directly everywhere
+- degrade cleanly to no-op behavior when disabled
+
+This keeps the rest of the codebase readable and makes it easy to reason about what telemetry is doing.
+
+## Logging Integration Strategy
+
+### Goal
+
+When a span is active, logs emitted through `loguru` during that operation should show up in the same trace.
+
+### Preferred design
+
+1. Configure Logfire once in the telemetry bootstrap
+2. Add the Logfire `loguru` handler to the existing `loguru` configuration
+3. At operation boundaries, bind stable contextual fields with `loguru`
+4. Let logs emitted inside the span inherit the active trace context
+
+### Context to bind
+
+Bind only the fields that help correlate work across the system:
+
+- `service_name`
+- `entrypoint`
+- `project_name`
+- `workspace_id`
+- `route_mode`
+- `tool_name`
+- `command_name`
+
+This binding should happen at the root of an operation, not deep in leaf functions.
+
+### Important nuance
+
+We should not try to encode the entire trace model into logger extras. The logger context should be a human-meaningful slice of the active operation. Trace linkage comes from the active Logfire/OpenTelemetry context; logger extras are there to improve searchability and readability.
+
+## Span Model
+
+### Root spans
+
+Each user-visible or system-visible operation should get one root span.
+
+Examples:
+
+- `cli.command.status`
+- `cli.command.project_sync`
+- `api.request.search`
+- `mcp.tool.write_note`
+- `mcp.tool.read_note`
+- `mcp.tool.search_notes`
+- `sync.project.run`
+- `db.semantic_backfill`
+
+### Child spans
+
+Child spans should represent real phases whose duration we care about.
+
+Examples:
+
+- `routing.client_session`
+- `routing.resolve_project`
+- `routing.resolve_workspace`
+- `api.search.execute`
+- `sync.project.scan`
+- `sync.project.detect_moves`
+- `sync.project.apply_changes`
+- `sync.project.resolve_relations`
+- `sync.project.sync_embeddings`
+- `sync.file.markdown`
+- `sync.file.regular`
+- `search.execute`
+- `search.relaxed_fts_retry`
+- `db.init`
+- `db.migrate`
+
+### Span naming rules
+
+- Use dot-separated names
+- Start with subsystem
+- Keep the verb at the end
+- Keep names stable across runs
+- Never include request-specific text in the span name
+
+## Attribute Taxonomy
+
+### Required attributes on root spans
+
+Every root span should have a small common set:
+
+- `service_name`
+- `entrypoint`
+- `project_name` when applicable
+- `workspace_id` when applicable
+- `route_mode` with values like `local_asgi`, `cloud_proxy`, `factory`
+
+### Operation-specific attributes
+
+Examples:
+
+For search:
+
+- `search_type`
+- `retrieval_mode`
+- `page`
+- `page_size`
+- `result_count`
+- `fallback_used`
+
+For sync:
+
+- `scan_type`
+- `force_full`
+- `new_count`
+- `modified_count`
+- `deleted_count`
+- `move_count`
+- `skipped_count`
+- `embeddings_enabled`
+
+For note operations:
+
+- `tool_name`
+- `note_type`
+- `directory`
+- `overwrite`
+- `output_format`
+
+### Attributes to avoid by default
+
+- full `query.text`
+- full note titles if they create privacy or cardinality issues
+- file content
+- raw frontmatter
+- raw HTTP bodies
+
+If we need richer payloads for a local debugging session, that should be an explicit temporary mode, not the default telemetry shape.
+
+## Instrumentation Plan By Layer
+
+### 1. Entrypoints
+
+Instrument these first:
+
+- `cli.app` callback and major commands
+- API lifespan and selected routers
+- MCP server lifespan
+- MCP tool entrypoints
+
+Why:
+
+- this establishes clean root spans
+- it gives us trace boundaries that match how users think about the product
+
+### 2. Routing and context resolution
+
+Instrument:
+
+- client routing decisions
+- workspace resolution
+- project resolution
+- default-project fallback
+
+Why:
+
+- Basic Memory has local/cloud/per-project routing logic
+- when something is slow or surprising, we need to know which path was taken
+
+### 3. Sync and indexing
+
+This is the highest-value area to instrument deeply.
+
+Instrument:
+
+- sync root
+- scan strategy decision
+- filesystem scan
+- move detection
+- delete handling
+- markdown sync phase
+- relation resolution
+- vector embedding sync
+- scan watermark update
+
+Why:
+
+- this is where performance work will happen
+- cloud and local both benefit from this visibility
+
+### 4. Search
+
+Instrument:
+
+- search execution
+- retrieval mode
+- relaxed FTS fallback
+- result shaping
+
+Why:
+
+- search is user-facing and latency-sensitive
+- hybrid/vector/FTS paths need to be distinguishable
+
+### 5. Database and initialization
+
+Instrument selectively:
+
+- DB init
+- migrations
+- semantic backfill
+- connection mode selection
+
+Avoid full automatic SQL span firehose by default.
+
+## Recommended Rollout Phases
+
+## Task List
+
+- [x] Phase 1: Bootstrap and config gating
+- [x] Phase 2: Root spans for entrypoints and primary operations
+- [x] Phase 3: Child spans for sync, search, and routing
+- [x] Phase 4: Failure-focused detail and final verification
+- [x] Phase 5: Loguru context binding and scoped context inheritance
+
+## Recommended Rollout Phases
+
+### Phase 1: Bootstrap and config gating
+
+Add:
+
+- telemetry bootstrap module
+- config/env gating
+- `loguru` + Logfire handler integration
+
+This gives immediate value with low noise.
+
+### Phase 2: Root spans for entrypoints and primary operations
+
+Add:
+
+- root spans for CLI, API, MCP, and main MCP tools
+- stable root attributes for project, workspace, route mode, and operation type
+
+This gives us clean top-level traces that match how users think about the product.
+
+### Phase 3: Child spans for sync, search, and routing
+
+Add child spans to:
+
+- sync
+- search
+- routing
+
+This is the main performance-investigation layer.
+
+### Phase 4: Failure-focused detail
+
+Add selective deeper spans/log enrichment for:
+
+- sync failures
+- relation resolution failures
+- slow file operations
+- cloud routing/auth failures
+
+This keeps normal traces clean while improving debuggability.
+
+### Phase 5: Loguru context binding and scoped context inheritance
+
+Add:
+
+- context-local telemetry state in `basic_memory.telemetry`
+- a shared `scope(...)` helper that opens a span and binds stable logger context together
+- context inheritance for routing, sync, and search so downstream `loguru` logs carry the active operation fields
+
+This makes the trace view and the log stream tell the same story without forcing logger rewrites across the codebase.
+
+## Local Dev Playbook
+
+The fastest way to sanity-check the current trace shape is:
+
+```bash
+LOGFIRE_TOKEN=lf_... just telemetry-smoke
+```
+
+What this does:
+
+- creates an isolated temp home, config dir, and project path
+- enables Logfire for the run
+- automatically exports to Logfire when `LOGFIRE_TOKEN` is present
+- defaults `BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=false` so the smoke run stays fast and trace-friendly
+- disables promo telemetry so the trace is about Basic Memory work, not analytics noise
+- runs a small CLI workflow:
+  - `project add`
+  - `tool write-note`
+  - `tool read-note`
+  - `tool edit-note`
+  - `tool build-context`
+  - `tool search-notes`
+  - `doctor`
+
+If you want to exercise the instrumentation without exporting anything upstream:
+
+```bash
+BASIC_MEMORY_LOGFIRE_SEND_TO_LOGFIRE=false just telemetry-smoke
+```
+
+If you want the smoke run to include vector or hybrid retrieval spans too:
+
+```bash
+LOGFIRE_TOKEN=lf_... BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true just telemetry-smoke
+```
+
+The recipe sets `BASIC_MEMORY_LOGFIRE_ENVIRONMENT=telemetry-smoke` by default so these traces are easy to isolate in Logfire. Override it if you want the smoke traces grouped under a different environment name.
+
+### What to look for
+
+You should see a small set of comparable root spans rather than a framework-generated span forest:
+
+- `cli.command.project`
+- `cli.command.tool`
+- `mcp.tool.write_note`
+- `mcp.tool.read_note`
+- `mcp.tool.edit_note`
+- `mcp.tool.build_context`
+- `mcp.tool.search_notes`
+- `sync.project.run`
+
+You should also see correlated logs under those traces with stable fields like:
+
+- `project_name`
+- `route_mode`
+- `tool_name`
+- `entrypoint`
+
+### Expected nuance
+
+`doctor` creates its own temporary project on purpose. That means the sync trace will usually show a different project name than the `telemetry-smoke` write/search traces. That is fine for smoke testing because the goal is to confirm:
+
+- root span names are meaningful
+- scoped logs stay attached to the active trace
+- routing, tool, search, and sync phases are easy to distinguish
+
+## Validation Checklist
+
+We should consider the integration successful when the following are true:
+
+1. With telemetry disabled, Basic Memory behaves exactly as it does today.
+2. With telemetry enabled, one user action produces one obvious root span.
+3. Logs emitted during that action are visible inside the same trace.
+4. A search in Logfire for `mcp.tool.write_note` or `sync.project.run` returns comparable spans across runs.
+5. Trace views show phase timing clearly without drowning in framework noise.
+6. Sensitive payloads are not captured by default.
+
+## Immediate Implementation Direction
+
+When we start coding, the first pass should be:
+
+1. Add `basic_memory.telemetry`
+2. Add config/env switches for `enabled`, `send_to_logfire`, and service name
+3. Wire telemetry bootstrap into CLI, API, and MCP entrypoints
+4. Configure `loguru` to emit to both existing sinks and the Logfire handler when enabled
+5. Add manual root spans around:
+   - CLI commands
+   - API request handlers we care about
+   - MCP tool entrypoints
+   - sync root
+   - search root
+6. Add child spans to the sync and routing phases only after the root span model feels clean
+
+That gives us a strong foundation without repeating the earlier "turn on instrumentation everywhere" approach.

+# MCP UI Bakeoff - Instructions & Test Plan
+
+Last updated: 2026-02-02
+
+## Scope
+
+Compare three presentation paths for Basic Memory MCP tools:
+
+1. **Tool‑UI (React)** via MCP App resources.
+2. **MCP‑UI Python SDK** embedded UI resources (legacy host path).
+3. **ASCII/ANSI** output for TUI clients.
+
+This doc is the running instruction set and test plan. Update as implementation progresses.
+
+---
+
+## Prerequisites
+
+- Repo: `basic-memory` (worktree: `basic-memory-mcp-ui-poc`)
+- Node for tool‑ui build (already used for POC)
+- Python 3.12+ with `uv`
+
+Optional (for MCP‑UI Python SDK path):
+
+- Local repo: `/Users/phernandez/dev/mcp-ui`
+- Install the server SDK into the Basic Memory venv:
+  - `uv pip install -e /Users/phernandez/dev/mcp-ui/sdks/python/server`
+
+---
+
+## Build / Refresh Steps
+
+### Tool‑UI React bundle
+
+```bash
+cd ui/tool-ui-react
+npm install
+npm run build
+```
+
+This regenerates:
+
+- `src/basic_memory/mcp/ui/html/search-results-tool-ui.html`
+- `src/basic_memory/mcp/ui/html/note-preview-tool-ui.html`
+
+---
+
+## How to Run the MCP Server
+
+```bash
+basic-memory mcp --transport stdio
+```
+
+Optional to pick UI variant for MCP App resources:
+
+```bash
+export BASIC_MEMORY_MCP_UI_VARIANT=tool-ui   # or vanilla | mcp-ui
+```
+
+---
+
+## Test Cases
+
+### 1) MCP App Resource UI (tool‑ui / vanilla / mcp‑ui)
+
+Tools:
+- `search_notes`
+- `read_note`
+
+Expect:
+- Tool meta points to `ui://basic-memory/search-results` and `ui://basic-memory/note-preview`
+- Resource content differs by `BASIC_MEMORY_MCP_UI_VARIANT`
+- Variant‑specific URIs also available:
+  - `ui://basic-memory/search-results/vanilla`
+  - `ui://basic-memory/search-results/tool-ui`
+  - `ui://basic-memory/search-results/mcp-ui`
+  - `ui://basic-memory/note-preview/vanilla`
+  - `ui://basic-memory/note-preview/tool-ui`
+  - `ui://basic-memory/note-preview/mcp-ui`
+
+Manual check:
+- Trigger tool in MCP‑App‑capable host and confirm UI renders.
+
+---
+
+### 2) Text / JSON Output Modes
+
+Tools:
+- `search_notes(output_format="text" | "json")`
+- `read_note(output_format="text" | "json")`
+- `write_note(output_format="text" | "json")`
+- `edit_note(output_format="text" | "json")`
+- `recent_activity(output_format="text" | "json")`
+- `list_memory_projects(output_format="text" | "json")`
+- `create_memory_project(output_format="text" | "json")`
+- `delete_note(output_format="text" | "json")`
+- `move_note(output_format="text" | "json")`
+- `build_context(output_format="json" | "text")`
+
+Expect:
+- `text` mode preserves existing human-readable responses.
+- `json` mode returns structured dict/list payloads for machine-readable clients.
+
+Automated:
+- `uv run pytest test-int/mcp/test_output_format_json_integration.py`
+
+---
+
+### 3) MCP‑UI Python SDK (embedded UI resource)
+
+Tools (embedded resource responses):
+- `search_notes_ui` (MCP‑UI SDK)
+- `read_note_ui` (MCP‑UI SDK)
+
+Expected output:
+- Tool response content contains an EmbeddedResource (`type: "resource"`)
+- `mimeType` is `text/html`
+- `_meta` includes:
+  - `mcpui.dev/ui-preferred-frame-size`
+  - `mcpui.dev/ui-initial-render-data`
+
+Manual check:
+- Render tool responses using `UIResourceRenderer` (legacy host flow).
+
+Automated (if SDK installed):
+- `uv run pytest test-int/mcp/test_ui_sdk_integration.py`

+# Metadata Search Reference
+
+Basic Memory automatically indexes custom frontmatter fields so you can query them with structured filters. Any YAML key in a note's frontmatter beyond the standard set (`title`, `type`, `tags`, `permalink`, `schema`) is stored as `entity_metadata` and becomes searchable.
+
+## Querying with `search_notes`
+
+`search_notes` is the single search tool for all queries — text, metadata filters, or both. The `query` parameter is optional, so you can use metadata filters alone without passing an empty string.
+
+## Filter Syntax
+
+Filters are a JSON dictionary where each key targets a frontmatter field and the value specifies the match condition. Multiple keys combine with **AND** logic — every filter must match.
+
+### Equality
+
+Match a single value exactly.
+
+```json
+{"status": "active"}
+```
+
+Finds notes whose frontmatter contains `status: active`.
+
+### Array Contains (all)
+
+Pass a list to require **all** listed values to be present in the field.
+
+```json
+{"tags": ["security", "oauth"]}
+```
+
+Finds notes tagged with both `security` and `oauth`.
+
+### `$in` (any of)
+
+Match if the field equals **any** value in the list.
+
+```json
+{"priority": {"$in": ["high", "critical"]}}
+```
+
+### `$gt`, `$gte`, `$lt`, `$lte`
+
+Numeric and text comparisons. Numeric values use numeric comparison; strings use lexicographic comparison.
+
+```json
+{"confidence": {"$gt": 0.7}}
+{"score": {"$lte": 100}}
+```
+
+### `$between`
+
+Range filter (inclusive). Takes a `[min, max]` pair.
+
+```json
+{"score": {"$between": [0.3, 0.8]}}
+```
+
+### Nested Access (dot notation)
+
+Access nested frontmatter values using dots.
+
+```json
+{"schema.version": "2"}
+```
+
+This queries the `version` key inside a `schema` object in frontmatter.
+
+### Summary Table
+
+| Operator | Syntax | Example |
+|----------|--------|---------|
+| Equality | `{"field": "value"}` | `{"status": "active"}` |
+| Array contains (all) | `{"field": ["a", "b"]}` | `{"tags": ["security", "oauth"]}` |
+| `$in` (any of) | `{"field": {"$in": [...]}}` | `{"priority": {"$in": ["high", "critical"]}}` |
+| `$gt` / `$gte` | `{"field": {"$gt": N}}` | `{"confidence": {"$gt": 0.7}}` |
+| `$lt` / `$lte` | `{"field": {"$lt": N}}` | `{"score": {"$lt": 0.5}}` |
+| `$between` | `{"field": {"$between": [min, max]}}` | `{"score": {"$between": [0.3, 0.8]}}` |
+| Nested access | `{"a.b": "value"}` | `{"schema.version": "2"}` |
+
+**Key rules:**
+- Filter keys must match `[A-Za-z0-9_-]+` (dots separate nesting levels).
+- Each operator dict must contain exactly one operator.
+- `$in` and array-contains require non-empty lists.
+- `$between` requires exactly two values `[min, max]`.
+
+## MCP Tool — `search_notes`
+
+`search_notes` is the single search tool for text queries, metadata filters, or both. The `query` parameter is optional.
+
+**Relevant parameters:**
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `query` | string (optional) | Text search query. Omit for filter-only searches. |
+| `metadata_filters` | dict | Structured filter dict (see syntax above) |
+| `tags` | list[str] | Convenience shorthand — merged into `metadata_filters["tags"]` |
+| `status` | string | Convenience shorthand — merged into `metadata_filters["status"]` |
+
+**Merging rules:** `tags` and `status` are convenience shortcuts. They are merged into `metadata_filters` using `setdefault` — if the same key already exists in `metadata_filters`, the explicit filter wins.
+
+**Examples:**
+
+```python
+# Text search filtered by metadata
+await search_notes("authentication", metadata_filters={"status": "draft"})
+
+# Filter-only search (no query needed)
+await search_notes(metadata_filters={"type": "spec"})
+
+# Combine text, tags shortcut, and metadata
+await search_notes(
+    "oauth flow",
+    tags=["security"],
+    metadata_filters={"confidence": {"$gt": 0.7}},
+)
+
+# Convenience shortcuts
+await search_notes("planning", status="active")
+await search_notes(tags=["tier1", "alpha"])
+```
+
+## Tag Search Shortcuts
+
+The `tag:` prefix in a search query is a shorthand for tag-based metadata filtering. When `search_notes` receives a query starting with `tag:`, it converts the query into a `tags` filter and clears the text query.
+
+```python
+# These are equivalent:
+await search_notes("tag:tier1")
+await search_notes("", tags=["tier1"])
+
+# Multiple tags (comma or space separated) — all must be present:
+await search_notes("tag:tier1,alpha")
+await search_notes("tag:tier1 alpha")
+```
+
+## CLI Access
+
+The `bm tool search-notes` command exposes metadata filtering via `--meta` and `--filter` flags.
+
+### `--meta` — simple key=value filters
+
+Repeatable flag for equality filters on frontmatter fields.
+
+```bash
+# Single filter
+bm tool search-notes "my query" --meta status=draft
+
+# Multiple filters (AND logic)
+bm tool search-notes "" --meta status=active --meta priority=high
+```
+
+### `--filter` — advanced JSON filters
+
+Pass a full JSON filter dictionary for operator-based queries.
+
+```bash
+# Range filter
+bm tool search-notes "" --filter '{"score": {"$between": [0.3, 0.8]}}'
+
+# $in filter
+bm tool search-notes "" --filter '{"priority": {"$in": ["high", "critical"]}}'
+```
+
+### `--tag` and `--status` — convenience shortcuts
+
+```bash
+bm tool search-notes "query" --tag security --tag oauth
+bm tool search-notes "" --status draft
+```
+
+### Combined example
+
+```bash
+bm tool search-notes "authentication" --tag security --meta status=draft --type spec
+```
+
+## Practical Examples
+
+### Example notes with custom frontmatter
+
+**`specs/auth-design.md`:**
+
+```markdown
+---
+title: Auth Design
+type: spec
+tags: [security, oauth]
+status: in-progress
+priority: high
+confidence: 0.85
+---

+
+## Observations
+- [decision] Use OAuth 2.1 with PKCE for all client types #security
+- [requirement] Token refresh must be transparent to the user
+
+## Relations

+```
+
+**`specs/search-redesign.md`:**
+
+```markdown

+# Search Redesign
+
+## Observations
+- [goal] Sub-100ms search response times #performance
+- [approach] Hybrid FTS + vector retrieval
+
+## Relations
+- depends_on [[Database Schema]]
+```
+
+### Queries that find them
+
+```python
+# Find all in-progress specs
+await search_notes(metadata_filters={"status": "in-progress", "type": "spec"})
+# → Auth Design
+
+# Find high-confidence specs
+await search_notes(metadata_filters={"confidence": {"$gt": 0.7}})
+# → Auth Design (confidence: 0.85)
+
+# Find specs with priority high or medium
+await search_notes(metadata_filters={"priority": {"$in": ["high", "medium"]}})
+# → Auth Design, Search Redesign
+
+# Find specs in a confidence range
+await search_notes(metadata_filters={"confidence": {"$between": [0.5, 0.9]}})
+# → Auth Design (0.85), Search Redesign (0.6)
+
+# Find notes tagged with security
+await search_notes("tag:security")
+# → Auth Design
+
+# Combined: text search + metadata filter
+await search_notes("OAuth", metadata_filters={"status": "in-progress"})
+# → Auth Design
+```
+
+### CLI equivalents
+
+```bash

+# Post-v0.18.0 Test Plan and Acceptance Criteria
+
+## Goal
+
+Define a complete validation plan for all major features merged after `v0.18.0`, combining:
+
+- Coverage-gap-driven automated tests
+- Real MCP server integration tests (no mocks for target flows)
+- Manual MCP verification via LLM-driven tool calls
+
+This plan is based on commits in `v0.18.0..HEAD` and the latest `just check` coverage output.
+
+## Scope Window
+
+- Start tag: `v0.18.0` (2026-01-28)
+- End: current `main`
+- Change volume: 12 feature commits + 14 bug-fix commits (+ release chores/hotfixes)
+
+## Execution Strategy
+
+1. Stabilize all feature-level acceptance criteria in automated tests first.
+2. Add black-box MCP integration tests for semantic search + schema (real server startup).
+3. Run manual MCP tool-call verification to confirm real UX and routing behavior.
+4. Re-run full gate: `just check` + targeted integration packs.
+
+## Global Quality Gates
+
+- Feature criteria below must all pass.
+- No regressions in existing suites.
+- Coverage improves in targeted low-coverage feature modules.

+- `tests/repository/test_search_repository.py`
+- `tests/services/test_search_service.py`
+
+### Planned additions — DONE
+
+- ~~Add Postgres-specific metadata filter edge-case tests to mirror SQLite assertions exactly.~~ **DONE** — `tests/repository/test_metadata_filters_edge_cases.py` (6 tests: missing field, AND logic, contains single-element array, nested path missing intermediate, $gte/$lte boundaries, $between inclusive — all pass on both SQLite and Postgres)
+
+### 9) Compatibility and Hotfix Regression Pack (`c46d7a6`, `a0e754b`, `343a6e1`, `24ca5f6`, `e3ced49`, `8489a3d`, `b609c4e`, `f6e0a5b`, `7624a20`)
+
+### Acceptance criteria
+
+- Legacy endpoints required by older CLI versions function without `405` (`GET /projects/projects`, `POST /projects/projects`, `POST /projects/config/sync`).
+- Entity creation conflicts map to conflict status (not 500).
+- `recent_activity` prompt defaults are correct.
+- No spurious `metadata: {}` in serialized frontmatter.
+- Tigris/rclone uses global consistency headers for all transaction types.
+- `bm --version` fast path avoids heavy import path and remains responsive.
+- Default SQLite DB path is isolated by config dir.
+
+### Gaps to close
+
+- ~~Commits with no direct tests added (`c46d7a6`, `344e651`, `f6e0a5b`) need explicit regression tests.~~ **DONE**
+
+### Planned additions — DONE
+
+- ~~Add API compat test covering all legacy endpoint methods and payloads.~~ **DONE** — `test_legacy_v1_add_project_endpoint`, `test_legacy_v1_sync_config_endpoint`
+- ~~Add CLI fast-path test for `--version` import behavior/performance guard.~~ **DONE** — `test_bm_version_does_not_import_heavy_modules`
+- ~~Add empty metadata serialization regression test.~~ **DONE** — `test_schema_to_markdown_empty_metadata_no_metadata_key`
+- Add migration safety test for SQLite generated columns (`VIRTUAL` expectation) — deferred, low risk.
+
+## MCP Manual Verification Plan (LLM Tool Calls)
+
+Run after automated tests pass.
+
+### Setup
+
+- Start MCP server: `basic-memory mcp --transport stdio`
+- Use an MCP-capable client and issue tool calls directly.
+
+### Manual scenarios
+
+- Schema: call `schema_validate`, `schema_infer`, and `schema_diff` on known fixtures.
+- Schema: verify error and success payloads match acceptance criteria.
+- Semantic search: call `search_notes` with `search_type=text|vector|hybrid`.
+- Semantic search: verify ranking relevance on semantic fixture queries.
+- Routing: call tools with explicit project on mixed local/cloud setup.
+- Routing: verify success/failure paths with and without API key.
+- Permalink routing: read/write/search notes across projects with colliding titles.
+- Permalink routing: verify memory URL routing correctness.
+- UI/TUI: call `search_notes` and `read_note` with UI variants and `output_format=text|json`.
+- UI/TUI: verify payload/resource format and metadata completeness.
+
+## Implementation Backlog (Ordered)
+
+1. ~~Fill schema MCP/client/router coverage gaps.~~ **DONE** — 18 tests in `test_tool_schema.py` + `test_client_schema.py`
+2. ~~Fill semantic search MCP + Postgres repository gaps.~~ **DONE** — 20 tests in `test_postgres_search_repository_unit.py` + `test_tool_search.py`
+3. ~~Add compatibility regression tests (legacy endpoints, migration, version fast path).~~ **DONE** — 5 tests across 3 files (see below)

+# v0.19.0 Release Notes
+
+## Overview
+
+v0.19.0 is a major release that introduces semantic vector search, a schema validation system,
+project-prefixed permalinks, per-project cloud routing, and a significant upgrade to FastMCP 3.0.
+It includes 90+ commits since v0.18.0 spanning new features, architectural improvements, and
+stability fixes across both SQLite and Postgres backends.
+
+---
+
+## Major Features
+
+### Semantic Vector Search
+
+Full vector and hybrid search for SQLite (via sqlite-vec) and Postgres (via pgvector).
+
+- **Hybrid search mode** combines full-text search (FTS) with vector similarity for best results
+- **Score-based fusion** replaces RRF for hybrid ranking — `max(vec, fts) + 0.3 * min(vec, fts)` preserves dominant signals and rewards dual-source agreement (#577)
+- **Default search mode** is now `hybrid` when semantic search is enabled, `text` when disabled
+- Embedding providers: FastEmbed (local, default) or OpenAI API
+- Configurable similarity threshold via `semantic_min_similarity` (default 0.55)
+- Per-query `min_similarity` override on `search_notes` tool
+- Auto-backfill: existing entities get embeddings generated on first startup
+- Backend-specific distance-to-similarity conversion (cosine for SQLite, inner product for Postgres)
+- FTS fallback: if semantic dependencies are missing, search gracefully degrades to text-only
+- sqlite-vec knn `k` parameter capped at 4096 to prevent backend errors
+
+**Configuration:**
+```json
+{
+  "semantic_search_enabled": true,
+  "semantic_embedding_provider": "fastembed",
+  "semantic_embedding_model": "bge-small-en-v1.5",
+  "semantic_min_similarity": 0.55
+}
+```
+
+**Usage:**
+```
+search_notes("machine learning concepts", search_type="hybrid")
+search_notes("similar to my notes on coffee", search_type="vector")
+search_notes("exact phrase match", search_type="text")
+search_notes("broad search", min_similarity=0.3)  # lower threshold for more results
+```
+
+### Schema System
+
+Validate note structure against user-defined schemas with frontmatter-based rules.
+
+- Define schemas as YAML in note frontmatter with field types, required fields, and constraints
+- Frontmatter validation during sync — malformed notes get clear error messages
+- Schema inference from existing notes to bootstrap schemas from your content
+- Schema diff to compare two schemas and see changes
+- Available via MCP tools and CLI
+
+### Project-Prefixed Permalinks
+
+Permalinks now include the project name for unambiguous cross-project references.
+
+- Memory URLs like `memory://project-name/folder/note` route to the correct project
+- Existing non-prefixed permalinks continue to work (backwards compatible)
+- Controlled by `permalinks_include_project` config (default: true)
+- `build_context` and `search_notes` auto-detect project from URL prefix
+
+### Per-Project Cloud Routing
+
+Individual projects can be routed through the cloud while others stay local.
+
+- Set a project to cloud mode: `bm project set-cloud research`
+- Revert to local: `bm project set-local research`
+- Uses API key authentication: `bm cloud set-key bmc_abc123...`
+- MCP tools automatically route based on each project's mode
+- Local MCP server (`bm mcp`) still uses local routing for all projects by default
+- `--local` and `--cloud` CLI flags override per-command
+
+### Workspace Selection
+
+Cloud projects can target specific workspaces for multi-tenant environments.
+
+- `workspace` parameter on MCP tools for explicit workspace targeting
+- CLI workspace-aware project listing with `bm project list`
+- Spinner feedback while fetching cloud projects
+
+---
+
+## New Tools and Capabilities
+
+### Dashboard (`bm project info`)
+
+`bm project info` now displays an htop-inspired compact dashboard with:
+
+- Horizontal bar charts for note types (top 5)
+- Embedding coverage bar with Unicode block characters
+- Colored status dots for at-a-glance health
+- `EmbeddingStatus` schema and `get_embedding_status()` service method for programmatic access
+
+### Unified Metadata Search
+
+`search_by_metadata` has been merged into `search_notes` — one tool for all searches.
+`query` is now optional, so you can search purely by frontmatter metadata.
+
+```
+search_notes(metadata_filters={"status": "in-progress"})
+search_notes(metadata_filters={"tags": ["security", "oauth"]})
+search_notes(metadata_filters={"priority": {"$in": ["high", "critical"]}})
+search_notes(metadata_filters={"schema.confidence": {"$gt": 0.7}})
+search_notes(tags=["security"])  # convenience shorthand
+search_notes(status="draft")     # convenience shorthand
+```
+
+### JSON Output Mode
+
+All MCP tools now support `output_format="json"` for machine-readable responses.
+
+- Default remains `"text"` for human-readable output (no breaking changes)
+- `build_context` defaults to `"json"` with slimmed payloads (redundant fields stripped)
+- CLI tool commands support `--format json` flag
+
+### `tag:` Search Shorthand
+
+Search by tag using convenient shorthand syntax.
+
+```
+search_notes("tag:security")
+search_notes("tag:coffee AND tag:brewing")
+```
+
+### Entity User Tracking
+
+Entities now track `created_by` and `last_updated_by` fields for attribution.
+
+### Improved Search Result Content (#609)
+
+Search results now surface more relevant context:
+
+- `matched_chunk_text` populated for FTS-only hybrid results (no more fallback to truncated content)
+- `TOP_CHUNKS_PER_RESULT` increased from 3 to 5, catching answers deeper in large notes (~2700 → ~4500 chars)
+- `CONTENT_DISPLAY_LIMIT` doubled from 2000 to 4000 chars for results without matched chunks
+
+### `write_note` Overwrite Guard (#632)
+
+`write_note` is now non-idempotent by default. If a note already exists, the tool returns an
+error instead of silently overwriting. Pass `overwrite=True` to replace, or use `edit_note`
+for incremental updates. Config option `write_note_overwrite_default` restores the old upsert
+behavior.
+
+---
+
+## Architecture Changes
+
+### Score-Based Hybrid Fusion (#577)
+
+RRF (Reciprocal Rank Fusion) compressed all fused scores to ~0.016, destroying ranking
+differentiation. The new formula `max(vec, fts) + FUSION_BONUS * min(vec, fts)` preserves
+dominant signals and rewards dual-source agreement. Zero-score results now produce zero
+fused score instead of receiving a 0.1 weight floor.
+
+### FastMCP 3.0 Upgrade
+
+Upgraded from FastMCP 2.12.3 to 3.0.1.
+
+- Tool annotations (`readOnlyHint`, `openWorldHint`) for better client integration
+- Improved MCP protocol compliance
+- Better error handling and context management
+
+### Prompts Call MCP Tools Directly
+
+MCP prompts (`search`, `continue_conversation`) now call MCP tools directly instead of
+going through API endpoints. This fixes empty results in discovery mode and ensures prompts
+use the same resolution logic as tools (including LinkResolver fallback).
+
+### build_context LinkResolver Fallback
+
+`build_context` now falls back to LinkResolver when an exact permalink lookup returns empty.
+This uses the same 7-strategy resolution pipeline as `read_note`, so callers no longer get
+empty results for valid note identifiers that don't match exact permalinks.
+
+### Sync Handles Semantic Dependency Errors Gracefully
+
+When sqlite-vec or another embedding provider is unavailable, `sync_file` now catches
+`SemanticDependenciesMissingError` separately. The entity is created and FTS-indexed
+successfully — only vector embeddings are skipped, with a clear warning:
+
+```
+WARNING: Semantic search dependencies missing — vector embeddings skipped for path=note.md.
+Run 'bm reindex --embeddings' after resolving the dependency issue.
+```
+
+### Unified Project Path
+
+Cloud projects with bisync now store the local filesystem path in `path` (not the Docker
+container path). Config migration automatically promotes `local_sync_path` → `path` for
+existing configs.
+
+---
+
+## CLI Improvements
+
+### Status and Doctor Default to Local Routing
+
+`bm status` and `bm doctor` now default to local routing since they scan the local filesystem.
+Previously, cloud-mode projects would route these commands to the cloud API, which returned
+Docker-internal paths that don't exist locally.
+
+### `--format json` for CLI Tool Commands
+
+All `bm tool` subcommands support `--format json` for machine-readable output, enabling
+integration with scripts and plugins.
+
+### `--json` for Top-Level CLI Commands
+
+Five additional CLI commands now support `--json` for machine-readable output:
+
+- `bm status --json` — sync report with new/modified/deleted/moved files and skipped files
+- `bm project list --json` — structured project list with name, paths, routing mode, and defaults
+- `bm schema validate --json` — validation report with per-note pass/fail, warnings, and errors
+- `bm schema infer --json` — field frequency analysis and suggested schema definition
+- `bm schema diff --json` — drift report with new fields, dropped fields, and cardinality changes
+
+This complements the existing `bm project info --json` and `bm tool --format json` support,
+making all major CLI commands scriptable for CI pipelines and automation.
+
+### Cloud Promo and Analytics
+
+- Cloud promo panel shown on first run or version bump with OSS discount code
+- Anonymous usage telemetry via Umami Cloud (promo/login funnel events only)
+- Opt out with `BASIC_MEMORY_NO_PROMOS=1`
+- No PII, no file contents, no per-command tracking
+- See [Telemetry](https://github.com/basicmachines-co/basic-memory#telemetry) in README
+
+---
+
+## Bug Fixes
+
+- **#577**: RRF fusion compressed all hybrid scores to ~0.016, destroying ranking differentiation
+- **#582**: build_context returns empty results on valid note identifiers
+- **#575**: Remove hardcoded "main" default from default_project
+- **#595**: recent_activity dedup and pagination across MCP tools
+- **#593**: Backend-specific distance-to-similarity conversion
+- **#592**: Strip NUL bytes from content before PostgreSQL search indexing
+- **#562**: Use VIRTUAL instead of STORED columns in SQLite migration
+- **#558**: Add X-Tigris-Consistent headers to all rclone commands
+- **#541**: Handle EntityCreationError as conflict
+- **#536**: Stabilize metadata filters on Postgres
+- **#533**: Fix recent_activity prompt defaults
+- **#530**: Prevent spurious `metadata: {}` in frontmatter output
+- **#601**: Return matched chunk text in search results
+- **#606**: Accept `null` for `expected_replacements` in `edit_note`
+- **#579, #607**: Guard against closed streams in promo panel and missing vector tables on shutdown
+- **#609**: FTS-only hybrid results missing `matched_chunk_text`; content limits too conservative
+- **#631**: `build_context` related_results schema validation failure — replaced fragile `_slim_context()` stripping with Pydantic `exclude=True` field config
+- **#630**: Skip workspace resolution when client factory is active — prevents 401 errors in cloud MCP server mode
+- **#30**: `tag:` prefix query fails with hybrid search — moved tag prefix parsing to MCP tool level so it works with all search modes
+- **#31**: `search_notes` returns cluttered observation/relation-level results — now defaults to entity-level results
+- **#28**: `schema_infer` and `schema_diff` return raw Pydantic models as "undefined" in LLM output — added markdown formatters
+- Fix `schema_validate` identifier resolution (now uses LinkResolver) and text rendering (markdown formatter)
+- **#634**: `schema_validate` and `schema_diff` use stale database metadata instead of reading schema definitions from file — now reads frontmatter directly from the file with fallback to database metadata
+- Fix `Post(**metadata)` crash when frontmatter contains `content` or `handler` keys
+- Fix list-valued frontmatter fields (`title`, `type`) crashing on `.strip()` — now coerced to strings
+- Cap sqlite-vec knn `k` parameter at 4096 to prevent backend errors
+- Parameterize SQL queries in search repository type filters
+- Double-default display in project list
+- `ensure_frontmatter_on_sync` default changed to `True`
+- Status/doctor commands fail with cloud-mode projects (Docker path error)
+- Prompts return "0 projects" in discovery mode
+
+---
+
+## Security
+
+- Upgrade `cryptography` for CVE advisory
+- Upgrade `python-multipart` for security advisory
+
+---
+
+## Internal / Developer
+
+- **#598**: Upgrade FastMCP 2.12.3 → 3.0.1 with tool annotations
+- **#594**: Add `ty` as supplemental type checker
+- **#538**: Add fast feedback loop tooling (`just fast-check`, `just doctor`, `just testmon`)
+- **#600**: Rename `entity_type` to `note_type` for consistency
+- **#596**: Fix CLI runtime defects and audit regressions
+- CLI refactoring and workspace-aware cloud project listing
+- Split and speed up PR test matrix in CI
+- Fix CI: collect coverage from test jobs instead of re-running all tests
+- Create `search_vector_chunks` in test fixtures for Postgres compatibility
+
+---
+
+## Configuration Changes
+
+| Setting | Old Default | New Default | Notes |
+|---------|-------------|-------------|-------|
+| `semantic_search_enabled` | `false` | `true` | Semantic search on by default |
+| `ensure_frontmatter_on_sync` | `false` | `true` | Frontmatter added during sync |
+| `permalinks_include_project` | `false` | `true` | Project prefix in permalinks |
+
+---
+
+## Upgrade Notes
+
+- **Semantic search dependencies** are now included by default. If sqlite-vec fails to load,
+  search gracefully falls back to FTS. Run `bm reindex --embeddings` to generate embeddings
+  for existing content.
+- **Hybrid search scoring** has changed from RRF to score-based fusion. Search result ordering
+  may differ — results should be more accurate with better score differentiation.
+- **`search_by_metadata`** is removed as a standalone tool. Use `search_notes` with
+  `metadata_filters` instead (same parameters, same behavior).
+- **Project-prefixed permalinks** are enabled by default. Existing notes keep their current
+  permalinks until modified. Set `permalinks_include_project: false` to disable.
+- **Frontmatter on sync** is now enabled by default. Files without frontmatter will have it
+  added on next sync. Set `ensure_frontmatter_on_sync: false` to preserve old behavior.
+- **Config migration** runs automatically for cloud projects with bisync — `local_sync_path`
+  is promoted to `path` so filesystem operations work correctly.
+- **`write_note` is no longer idempotent** — calls to `write_note` for existing notes now
+  return an error unless `overwrite=True` is passed. Use `edit_note` for incremental changes,
+  or set `write_note_overwrite_default: true` in config to restore the old behavior.

+# Semantic Search Manual Test Log
+
+## Overview
+
+Manual test session for semantic (vector) search on the main project.
+- Date: 2026-02-15
+- Database: ~/.basic-memory/memory.db (SQLite)
+- Entities: 456 embedded, 2714 vector chunks
+- Search index: 2390 FTS entries
+- Embedding model: default (384-dim, sqlite-vec)
+
+## Test Plan
+
+1. **Search Type Routing** — verify vector/hybrid/text dispatch, invalid search_type handling
+2. **Conceptual Queries** — natural language where vector should beat FTS
+3. **Keyword Queries** — exact terms where FTS should be strong
+4. **Hybrid Ranking** — queries where both FTS and vector contribute
+5. **Result Types** — entities, observations, relations in vector results
+6. **Filters + Vector** — combine vector with types/entity_types/after_date
+7. **Edge Cases** — short queries, long queries, empty, special chars, no-match
+8. **Pagination** — page > 1, page_size respected
+
+---
+
+## Test Results
+
+### Test 1: Search Type Routing
+
+#### 1a: search_type="semantic" (invalid value)
+- **Input:** query="how does the knowledge graph work", search_type="semantic"
+- **Expected:** error or explicit fallback
+- **Actual:** Silently falls through to text search (else branch in search.py:430)
+- **Verdict:** BUG — should either be a recognized alias for "vector" or return an error
+
+#### 1b: search_type="vector"
+- **Input:** query="keeping AI context between sessions", search_type="vector"
+- **Actual:** 5 results, scores ~0.58-0.59, found "Maintaining context across conversation boundaries" observation
+- **Verdict:** PASS
+
+#### 1c: search_type="text" with conceptual query
+- **Input:** query="keeping AI context between sessions", search_type="text"
+- **Actual:** 0 results (no exact keyword match)
+- **Verdict:** PASS (expected — FTS requires token overlap)
+
+#### 1d: search_type="hybrid" with conceptual query
+- **Input:** query="keeping AI context between sessions", search_type="hybrid"
+- **Actual:** 5 results, same ranking as vector (FTS contributed nothing here)
+- **Verdict:** PASS
+
+#### 1e: search_type="text" with keyword query
+- **Input:** query="OAuth authentication", search_type="text"
+- **Actual:** 3 results — AUTH.md Supabase OAuth, OAuth Rip-and-Replace, OAuth Integration Analysis
+- **Verdict:** PASS
+
+#### 1f: search_type="vector" with keyword query
+- **Input:** query="OAuth authentication", search_type="vector"
+- **Actual:** Same top results as text (keyword-rich content also scores well in vector space)
+- **Verdict:** PASS
+
+---
+
+### Test 2: Conceptual Queries (vector advantage)
+
+#### 2a: Natural language question
+- **Input:** query="why do AI assistants forget things", search_type="vector"
+- **Actual:** 5 results — Manual Testing Session, "Balance security and usability" observation, "Tools should match thought patterns" observation. Scores ~0.56-0.57
+- **Vector advantage:** Found conceptually related content despite no exact keyword overlap
+- **Verdict:** PASS
+
+#### 2b: Same query, text search
+- **Input:** query="why do AI assistants forget things", search_type="text"
+- **Actual:** 1 result — "What is Basic Memory?" (likely matched on "AI" token)
+- **Verdict:** PASS (demonstrates vector advantage — text barely matched)
+
+#### 2c: Domain concept with no jargon
+- **Input:** query="pricing strategy for cloud product", search_type="vector"
+- **Actual:** 3 results — SPEC-16 MCP Cloud Service Consolidation, knowledge architecture observation, Visual Knowledge Spaces relation. Scores ~0.56-0.57
+- **Verdict:** PASS (found cloud-related content conceptually)
+
+#### 2d: Technical concept, long query
+- **Input:** query="SQLite performance optimization WAL mode concurrent writes", search_type="vector"
+- **Actual:** 3 results — SPEC-11 API Performance Optimization, Real-Time Updates with WebSockets, marketing status update. Scores ~0.55-0.58
+- **Verdict:** PASS (found performance-related content)
+
+---
+
+### Test 3: Keyword Queries (FTS strength)
+
+#### 3a: Exact term match — "OAuth authentication"
+- **Text:** 3 results with high relevance (exact matches in titles)
+- **Vector:** Same top results (keyword overlap helps vector too)
+- **Verdict:** PASS — FTS and vector converge on keyword-rich queries
+
+#### 3b: "OAuth" single keyword, hybrid mode
+- **Input:** query="OAuth", search_type="hybrid"
+- **Actual:** 5 results — Basic Memory Coding Guide, AI Collaboration Examples, SPEC-18, daily note, Manual Testing Session. FTS + vector blended. Scores ~0.016-0.032
+- **Note:** Top hybrid result is "Basic Memory Coding Guide" not an OAuth-specific doc — suggests hybrid scoring may dilute strong FTS matches
+- **Verdict:** PASS but hybrid ranking questionable for single-keyword queries
+
+---
+
+### Test 4: Hybrid Ranking
+
+#### 4a: Hybrid vs vector on "OAuth authentication"
+- **Hybrid with entity_types=["entity"]:** 5 results — RLS Implementation Lessons, Cloud Readiness Assessment, AUTH.md OAuth, Core Service Implementation, OAuth Rip-and-Replace. Scores ~0.016-0.023
+- **Vector with entity_types=["entity"]:** 5 results — Core Service Implementation, SPEC-13 CLI Auth, Coding Guide, Authentication Service, ADR Production Auth. Scores ~0.55-0.60
+- **Observation:** Hybrid surfaces different top results than vector-only. Hybrid found RLS and Cloud Readiness docs that vector didn't prioritize. Different ranking is expected from RRF fusion.
+- **Verdict:** PASS — hybrid produces meaningfully different ranking
+
+---
+
+### Test 5: Result Types
+
+#### 5a: Vector returns all result types
+- **Input:** query="keeping AI context between sessions", search_type="vector"
+- **Entities:** SPEC-18 AI Memory Management Tool (type=entity)
+- **Relations:** Prompt Builder integrates_with (type=relation)
+- **Observations:** "Translation layer is key" (type=observation), "Maintaining context across conversation boundaries" (type=observation)
+- **Verdict:** PASS — all three types appear in vector results
+
+#### 5b: Observations carry metadata
+- **Observation result:** category="challenge", content="Maintaining context across conversation boundaries", from_entity="research/ai-knowledge-management-research"
+- **Verdict:** PASS — category, content, from_entity, tags all present
+
+#### 5c: Relations carry link info
+- **Relation result:** relation_type="integrates_with", from_entity="development/features/prompt-builder...", to_entity (present but truncated in some)
+- **Verdict:** PASS — relation metadata present
+
+---
+
+### Test 6: Filters + Vector Search
+
+#### 6a: entity_types=["entity"] with vector
+- **Input:** query="OAuth authentication", search_type="vector", entity_types=["entity"]
+- **Actual:** 5 results, all type="entity" (Core Service Implementation, SPEC-13, Coding Guide, Authentication Service, ADR Auth)
+- **Verdict:** PASS — filter correctly restricts to entities only
+
+#### 6b: types=["note"] with vector
+- **Input:** query="OAuth authentication", search_type="vector", types=["note"]
+- **Actual:** Same 5 results (all have entity_type="note" in metadata)
+- **Verdict:** PASS — types filter works with vector search
+
+#### 6c: after_date with vector
+- **Input:** query="OAuth authentication", search_type="vector", after_date="2025-06-01"
+- **Actual:** 3 results — Core Service Implementation, Cloud Web App analysis observation, SPEC-13. Filtered out older OAuth docs.
+- **Verdict:** PASS — date filter applied correctly
+
+#### 6d: entity_types=["entity"] with hybrid
+- **Input:** query="OAuth authentication", search_type="hybrid", entity_types=["entity"]
+- **Actual:** 5 results, all type="entity" — RLS lessons, Cloud Readiness, AUTH.md OAuth, Core Service, OAuth Rip-and-Replace
+- **Verdict:** PASS — filter works with hybrid mode too
+
+#### 6e: types=["entity"] with vector (WRONG filter name)
+- **Input:** query="OAuth authentication", search_type="vector", types=["entity"]
+- **Actual:** 0 results
+- **Note:** `types` filters by entity_type metadata (e.g., "note", "person"), NOT by SearchItemType. Using types=["entity"] looks for entity_type="entity" which few/no notes have. This is a UX confusion point — the param names are ambiguous.
+- **Verdict:** PASS (correct behavior) but USABILITY ISSUE — easy to confuse types vs entity_types
+
+---
+
+### Test 7: Edge Cases
+
+#### 7a: Single character query
+- **Input:** query="x", search_type="vector"
+- **Actual:** 3 results — "Self-contained application bundle" observation, Non-Markdown File Support relation, quick-win-tools entity. Scores ~0.57-0.59
+- **Note:** Single character still produces an embedding and returns results. Quality is low/random as expected.
+- **Verdict:** PASS (no crash, returns results)
+
+#### 7b: Whitespace-only query
+- **Input:** query="   ", search_type="vector"
+- **Actual:** 0 results
+- **Verdict:** PASS (handled gracefully — _check_vector_eligible strips and rejects empty)
+
+#### 7c: Query with no relevant content
+- **Input:** query="quantum computing blockchain", search_type="vector"
+- **Actual:** 3 results — Inter-Agent Communication relation, Self-contained bundle observation, JSON-LD interop observation. Scores ~0.54
+- **Note:** Still returns results because vector search always finds nearest neighbors. Scores are lower (~0.54) than relevant queries (~0.58-0.60). No relevance threshold applied.
+- **Verdict:** PASS (expected behavior) but NOTE — no relevance cutoff means irrelevant queries always return something
+
+---
+
+### Test 8: Pagination
+
+#### 8a: Vector search page 2
+- **Input:** query="keeping AI context between sessions", search_type="vector", page=2, page_size=3
+- **Actual:** 3 results on page 2, current_page=2. Different results from page 1. Top: "Maintaining context across conversation boundaries" observation (score 0.587)
+- **Note:** Interestingly, page 2 had a higher-scoring result than some page 1 results. This may indicate pagination doesn't sort globally — it might be paginating within a pre-scored set.
+- **Verdict:** PASS (pagination works) but POSSIBLE ISSUE — result ordering across pages needs investigation
+
+---
+
+## Summary
+
+### Passing Tests: 20/21
+
+### Bugs Found
+1. **search_type="semantic" silently falls through** (Test 1a) — Invalid search_type values fall to the `else` branch and default to text search without any warning. Should either alias "semantic" to "vector" or raise an error.
+
+### Usability Issues
+2. **types vs entity_types confusion** (Test 6e) — `types` filters by entity_type metadata (note, person, etc.) while `entity_types` filters by SearchItemType (entity, observation, relation). The naming is ambiguous and easy to mix up.
+3. **No relevance threshold** (Test 7c) — Vector search always returns nearest neighbors even for completely irrelevant queries. Consider adding a minimum score threshold or at least documenting expected score ranges.
+4. **Hybrid ranking for single keywords** (Test 3b) — Hybrid mode on simple keyword queries produced less intuitive rankings than pure FTS or pure vector. The RRF fusion may dilute strong FTS signals.
+
+### Observations
+- Vector search successfully finds conceptually related content that FTS misses entirely
+- Score ranges: relevant queries ~0.56-0.60, irrelevant queries ~0.54 (narrow spread)
+- All three result types (entity, observation, relation) appear correctly in vector results
+- Filters (entity_types, types, after_date) all work correctly with vector and hybrid modes
+- Pagination works but cross-page ordering may need investigation

+# Semantic Search
+
+This guide covers Basic Memory's semantic (vector) search feature, which adds meaning-based retrieval alongside the existing full-text search.
+
+## Overview
+
+Basic Memory's search supports both full-text search (FTS) and semantic retrieval. Semantic search adds vector embeddings that capture the *meaning* of your content, enabling:
+
+- **Paraphrase matching**: Find "authentication flow" when searching for "login process"
+- **Conceptual queries**: Search for "ways to improve performance" and find notes about caching, indexing, and optimization
+- **Hybrid retrieval**: Combine the precision of keyword search with the recall of semantic similarity
+
+Semantic search is enabled by default when semantic dependencies are available at runtime. It works on both SQLite (local) and Postgres (cloud) backends.
+
+## Installation
+
+Semantic search dependencies (fastembed, sqlite-vec, openai) are included in the default `basic-memory` install.
+
+```bash
+pip install basic-memory
+```
+
+You can always override with `BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true|false`.
+
+### Platform Compatibility
+
+| Platform | FastEmbed (local) | OpenAI (API) |
+|---|---|---|
+| macOS ARM64 (Apple Silicon) | Yes | Yes |
+| macOS x86_64 (Intel Mac) | No — see workaround below | Yes |
+| Linux x86_64 | Yes | Yes |
+| Linux ARM64 | Yes | Yes |
+| Windows x86_64 | Yes | Yes |
+
+#### Intel Mac Workaround
+
+The default install includes FastEmbed, which depends on ONNX Runtime. ONNX Runtime dropped Intel Mac (x86_64) wheels starting in v1.24, so install with a compatible ONNX Runtime pin first:
+
+```bash
+pip install basic-memory 'onnxruntime<1.24'
+```
+
+After installation, Intel Mac users have two runtime options:
+
+**Option 1: Use OpenAI embeddings (recommended)**
+
+```bash
+export BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true
+export BASIC_MEMORY_SEMANTIC_EMBEDDING_PROVIDER=openai
+export OPENAI_API_KEY=sk-...
+```
+
+**Option 2: Use FastEmbed locally**
+
+Keep the same pinned installation and use FastEmbed (default provider):
+
+```bash
+export BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true
+export BASIC_MEMORY_SEMANTIC_EMBEDDING_PROVIDER=fastembed
+```
+
+## Quick Start
+
+1. Install Basic Memory:
+
+```bash
+pip install basic-memory
+```
+
+2. (Optional) Explicitly enable semantic search:
+
+```bash
+export BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true
+```
+
+3. Build vector embeddings for your existing content:
+
+```bash
+bm reindex --embeddings
+```
+
+4. Search using semantic modes:
+
+```python
+# Pure vector similarity
+search_notes("login process", search_type="vector")
+
+# Hybrid: combines FTS precision with vector recall (recommended)
+search_notes("login process", search_type="hybrid")
+
+# Explicit full-text search
+search_notes("login process", search_type="text")
+```
+
+## Configuration Reference
+
+All settings are fields on `BasicMemoryConfig` and can be set via environment variables (prefixed with `BASIC_MEMORY_`).
+
+| Config Field | Env Var | Default | Description |
+|---|---|---|---|
+| `semantic_search_enabled` | `BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED` | Auto (`true` when semantic deps are available) | Enable semantic search. Required before vector/hybrid modes work. |
+| `semantic_embedding_provider` | `BASIC_MEMORY_SEMANTIC_EMBEDDING_PROVIDER` | `"fastembed"` | Embedding provider: `"fastembed"` (local) or `"openai"` (API). |
+| `semantic_embedding_model` | `BASIC_MEMORY_SEMANTIC_EMBEDDING_MODEL` | `"bge-small-en-v1.5"` | Model identifier. Auto-adjusted per provider if left at default. |
+| `semantic_embedding_dimensions` | `BASIC_MEMORY_SEMANTIC_EMBEDDING_DIMENSIONS` | Auto-detected | Vector dimensions. 384 for FastEmbed, 1536 for OpenAI. Override only if using a non-default model. |
+| `semantic_embedding_batch_size` | `BASIC_MEMORY_SEMANTIC_EMBEDDING_BATCH_SIZE` | `64` | Number of texts to embed per batch. |
+| `semantic_vector_k` | `BASIC_MEMORY_SEMANTIC_VECTOR_K` | `100` | Candidate count for vector nearest-neighbour retrieval. Higher values improve recall at the cost of latency. |
+
+## Embedding Providers
+
+### FastEmbed (default)
+
+FastEmbed runs entirely locally using ONNX models — no API key, no network calls, no cost.
+
+- **Model**: `BAAI/bge-small-en-v1.5`
+- **Dimensions**: 384
+- **Tradeoff**: Smaller model, fast inference, good quality for most use cases
+
+```bash
+# Install basic-memory and enable semantic search
+pip install basic-memory
+export BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true
+```
+
+### OpenAI
+
+Uses OpenAI's embeddings API for higher-dimensional vectors. Requires an API key.
+
+- **Model**: `text-embedding-3-small`
+- **Dimensions**: 1536
+- **Tradeoff**: Higher quality embeddings, requires API calls and an OpenAI key
+
+```bash
+export BASIC_MEMORY_SEMANTIC_SEARCH_ENABLED=true
+export BASIC_MEMORY_SEMANTIC_EMBEDDING_PROVIDER=openai
+export OPENAI_API_KEY=sk-...
+```
+
+When switching from FastEmbed to OpenAI (or vice versa), you must rebuild embeddings since the vector dimensions differ:
+
+```bash
+bm reindex --embeddings
+```
+
+## Search Modes
+
+### `text` (default)
+
+Full-text keyword search using FTS5 (SQLite) or tsvector (Postgres). Supports boolean operators (`AND`, `OR`, `NOT`), phrase matching, and prefix wildcards.
+
+```python
+search_notes("project AND planning", search_type="text")
+```
+
+This is the existing default and does not require semantic search to be enabled.
+
+### `vector`
+
+Pure semantic similarity search. Embeds your query and finds the nearest content vectors. Good for conceptual or paraphrase queries where exact keywords may not appear in the content.
+
+```python
+search_notes("how to speed up the app", search_type="vector")
+```
+
+Returns results ranked by cosine similarity. Individual observations and relations surface as first-class results, not collapsed into parent entities.
+
+### `hybrid`
+
+Combines FTS and vector results using score-based fusion. This is generally the best mode when you want both keyword precision and semantic recall.
+
+```python
+search_notes("authentication security", search_type="hybrid")
+```
+
+Score-based fusion uses the formula `max(vec, fts) + bonus * min(vec, fts)` to preserve the dominant signal while rewarding results found by both methods.
+
+### When to Use Which
+
+| Mode | Best For |
+|---|---|
+| `text` | Exact keyword matching, boolean queries, tag/category searches |
+| `vector` | Conceptual queries, paraphrase matching, exploratory searches |
+| `hybrid` | General-purpose search combining precision and recall |
+
+## The Reindex Command
+
+The `bm reindex` command rebuilds search indexes without dropping the database.
+
+```bash
+# Rebuild everything (FTS + embeddings if semantic is enabled)
+bm reindex
+
+# Only rebuild vector embeddings
+bm reindex --embeddings
+
+# Only rebuild the full-text search index
+bm reindex --search
+
+# Target a specific project
+bm reindex -p my-project
+```
+
+### When You Need to Reindex
+
+- **Upgrade note**: Migration now performs a one-time automatic embedding backfill on upgrade.
+- **Manual enable case**: If you explicitly had `semantic_search_enabled=false` and then turn it on
+- **Provider change**: After switching between `fastembed` and `openai`
+- **Model change**: After changing `semantic_embedding_model`
+- **Dimension change**: After changing `semantic_embedding_dimensions`
+
+The reindex command shows progress with embedded/skipped/error counts:
+
+```
+Project: main
+  Building vector embeddings...
+  ✓ Embeddings complete: 142 entities embedded, 0 skipped, 0 errors
+
+Reindex complete!
+```
+
+## How It Works
+
+### Chunking
+
+Each entity in the search index is split into semantic chunks before embedding:
+
+- **Headers**: Markdown headers (`#`, `##`, etc.) start new chunks
+- **Bullets**: Each bullet item (`-`, `*`) becomes its own chunk for granular fact retrieval
+- **Prose sections**: Non-bullet text is merged up to ~900 characters per chunk
+- **Long sections**: Oversized content is split with ~120 character overlap to preserve context at boundaries
+
+Each search index item type (entity, observation, relation) is chunked independently, so observations and relations are embeddable as discrete facts.
+
+### Deduplication
+
+Each chunk has a `source_hash` (SHA-256 of the chunk text). On re-sync, unchanged chunks skip re-embedding entirely. This makes incremental updates fast — only modified content triggers API calls or model inference.
+
+### Hybrid Fusion
+
+Hybrid search uses score-based fusion to merge FTS and vector results:
+
+1. Run FTS search to get keyword-ranked results; normalize scores to [0, 1]
+2. Run vector search to get similarity-ranked results (already [0, 1])
+3. For each result, compute: `fused = max(vec_score, fts_score) + 0.3 * min(vec_score, fts_score)`
+4. Sort by fused score
+
+The dominant signal (whichever source scored higher) is preserved, and dual-source agreement adds a bonus. Unlike rank-based fusion, this approach retains score magnitude — a strong vector match stays strong even without an FTS hit.
+
+### Observation-Level Results
+
+Vector and hybrid modes return individual observations and relations as first-class search results, not just parent entities. This means a search for "water temperature for brewing" can surface the specific observation about 205°F without returning the entire "Coffee Brewing Methods" entity.
+
+## Database Backends
+
+### SQLite (local)
+
+- **Vector storage**: [sqlite-vec](https://github.com/asg017/sqlite-vec) virtual table
+- **Table creation**: At runtime when semantic search is first used — no migration needed
+- **Embedding table**: `search_vector_embeddings` using `vec0(embedding float[N])` where N is the configured dimensions
+- **Chunk metadata**: `search_vector_chunks` table stores chunk text, keys, and source hashes
+
+The sqlite-vec extension is loaded per-connection. Vector tables are created lazily on first use.
+
+### Postgres (cloud)
+
+- **Vector storage**: [pgvector](https://github.com/pgvector/pgvector) with HNSW indexing
+- **Chunk metadata table**: Created via Alembic migration (`search_vector_chunks` with `BIGSERIAL` primary key)
+- **Embedding table**: `search_vector_embeddings` created at runtime (dimension-dependent, same pattern as SQLite)
+- **Index**: HNSW index on the embedding column for fast approximate nearest-neighbour queries
+
+The Alembic migration creates the dimension-independent chunks table. The embeddings table and HNSW index are deferred to runtime because they depend on the configured vector dimensions.

+# SPEC-LOCAL-PLUS-PUBLISH: Local+ Published Notes and Privacy Tiers
+
+**Status:** Draft  
+**Date:** 2026-02-14  
+**Owner:** Basic Memory
+
+## Summary
+
+Add a paid Local+ feature that lets users publish selected notes to shareable URLs while keeping the
+main knowledge base local-first. Use this as a product wedge for users who do not want full cloud
+hosting but do want collaboration and distribution features.
+
+This spec also captures a practical position on "zero knowledge" for Local+.
+
+## Context
+
+Basic Memory already has strong local-first primitives and optional cloud routing/sync. A recurring
+request is:
+
+- keep knowledge local by default,
+- pay for selective value-add,
+- share specific outputs externally.
+
+Published Notes fits this model: explicit per-note opt-in, reversible, and easy to understand.
+
+## Goals
+
+1. Provide an Obsidian Publish-style sharing experience for selected notes.
+2. Keep local markdown files as source of truth.
+3. Make sharing compatible with current cloud/auth/billing primitives.
+4. Define clear Local+ packaging that does not degrade OSS local workflows.
+5. Document zero-knowledge constraints so product decisions are explicit.
+
+## Non-Goals
+
+1. Full hosted editing for all notes (Cloud Full remains separate).
+2. Public website builder/CMS features.
+3. Strict cryptographic zero-knowledge server processing for MCP/search in v1.
+
+## Local+ Feature Catalog (Sellable)
+
+Core Local+ candidates:
+
+1. Published Notes (share URL, revoke, expiry, password).
+2. Snapshot Time Machine (point-in-time restore for local projects).
+3. Recovery Drill Reports (automated restore verification).
+4. Device/API Key Governance (per-device keys, revocation, audit trail).
+5. BYO Storage Orchestration (managed setup for user-owned object storage).
+6. Semantic Boost Add-on (higher quality retrieval options while files remain source-of-truth).
+
+Team-oriented add-ons:
+
+1. Team-owned shared links and domain branding.
+2. Role-based publish permissions.
+3. Shared workspace policies for what can be published.
+
+## Proposed MVP: Published Notes
+
+### User Experience
+
+Per note actions:
+
+1. Publish.
+2. Unpublish.
+3. Copy URL.
+4. Regenerate URL.
+5. Set visibility and controls.
+
+Controls:
+
+1. Visibility: `unlisted` (default) or `public`.
+2. Optional password gate.
+3. Optional expiration datetime.
+4. Optional "disable indexing" flag for public mode.
+
+Behavior:
+
+1. Source note remains local markdown.
+2. Publish is explicit opt-in per note.
+3. Unpublish removes public access immediately.
+4. Republish creates a new URL token unless user chooses to keep current URL.
+
+### URL Model
+
+1. Unlisted share URL: high-entropy token path.
+2. Public URL: slug path (optional, later phase).
+3. Team plans can support custom domain mapping in later phase.
+
+### Content Model
+
+v1 published page includes:
+
+1. Rendered markdown body.
+2. Optional metadata (title, updated_at).
+
+v1 excludes:
+
+1. Full graph traversal expansion.
+2. Related note auto-discovery on public pages.
+
+### Sync Model
+
+1. Local file remains canonical.
+2. Publish stores a rendered snapshot plus metadata in cloud.
+3. Update path:
+   - manual "update published version", or
+   - optional auto-update on note change (plan-gated).
+
+## Architecture (v1)
+
+### High-Level Flow
+
+1. Client selects a note to publish.
+2. Client sends publish request with note identifier and policy.
+3. Service resolves note content (local sync artifact or explicit upload payload).
+4. Service stores published artifact and returns share URL.
+
+### Data Model
+
+`published_notes`
+
+1. `id` (uuid)
+2. `tenant_id` or `workspace_id`
+3. `project_id`
+4. `entity_permalink` (or stable external_id)
+5. `share_token` (hashed in DB)
+6. `visibility` (`unlisted`|`public`)
+7. `password_hash` (nullable)
+8. `expires_at` (nullable)
+9. `is_active`
+10. `published_content` (rendered snapshot or reference)
+11. `published_at`
+12. `updated_at`
+
+### API Shape (Draft)
+
+1. `POST /api/published-notes`
+2. `GET /api/published-notes`
+3. `GET /api/published-notes/{id}`
+4. `PATCH /api/published-notes/{id}`
+5. `DELETE /api/published-notes/{id}` (unpublish)
+6. `POST /api/published-notes/{id}/regenerate-url`
+7. `GET /p/{token}` (public resolver)
+
+### CLI Shape (Draft)
+
+1. `bm cloud publish <identifier>`
+2. `bm cloud publish list`
+3. `bm cloud publish update <id>`
+4. `bm cloud publish unpublish <id>`
+5. `bm cloud publish rotate-url <id>`
+
+### Security
+
+1. Default to unlisted URLs.
+2. Store only hashed share tokens.
+3. Passwords hashed server-side.
+4. Enforce expiration at request time.
+5. Log publish/unpublish/rotate events for auditability.
+
+## Packaging and Pricing Direction
+
+Suggested split:
+
+1. OSS Local: no publish URLs.
+2. Local+ Solo: publish URLs + snapshots + recovery.
+3. Local+ Team: solo features + team governance and branding.
+4. Cloud Full: hosted app + full cloud workflows.
+
+Key message:
+"Keep everything local. Publish only what you choose."
+
+## Rollout Plan
+
+1. Phase 1: Unlisted publish URLs + unpublish + regenerate URL.
+2. Phase 2: Password/expiry controls.
+3. Phase 3: Auto-update on note change and basic analytics.
+4. Phase 4: Team branding/domains/policies.
+
+## Zero-Knowledge Position
+
+### Strict Zero-Knowledge Definition
+
+Strict zero-knowledge means the server cannot decrypt note content at all.
+
+### Why This Conflicts with MCP and Search
+
+If server cannot decrypt:
+
+1. MCP tool execution against cloud content cannot read/write semantic content.
+2. Full-text search cannot index plaintext content.
+3. Semantic/vector search cannot generate or query embeddings on plaintext.
+4. Server-side relation resolution and context building become severely limited.
+
+This matches earlier findings: strict zero-knowledge materially handicaps MCP-driven behavior and
+search quality.
+
+### Viable Alternatives (Not Strict Zero-Knowledge)
+
+1. Encryption at rest/in transit with server-side decrypt in trusted runtime.
+   - Preserves MCP/search quality.
+   - Not zero-knowledge cryptographically.
+
+2. Client-side retrieval mode.
+   - Keep MCP/search local; cloud is sync/share/backup relay.
+   - Best for privacy-first users.
+   - Requires local agent availability for advanced retrieval.
+
+3. Limited encrypted indexing.
+   - Blind indexes for exact keywords only.
+   - No high-quality semantic search.
+   - Usually poor UX for natural-language memory recall.
+
+### Recommendation
+
+For Local+:
+
+1. Do not promise strict zero-knowledge for cloud MCP/search paths.
+2. Offer a privacy-first local mode where advanced retrieval stays local.
+3. Clearly label tradeoffs:
+   - "Local private mode" (best privacy, best local retrieval).
+   - "Cloud-assisted mode" (best cross-device/MCP consistency, trusted-runtime decrypt).
+
+This keeps messaging honest and avoids repeating the known incompatibility.

+# SPEC-SCHEMA-IMPL: Schema System Implementation Plan
+
+**Status:** Draft
+**Created:** 2025-02-06
+**Branch:** `feature/schema-system`
+**Depends on:** [SPEC-SCHEMA](SPEC-SCHEMA.md)
+
+## Overview
+
+Implementation plan for the Basic Memory Schema System. The system is entirely programmatic —
+no LLM agent runtime or API key required. The LLM already in the user's session (Claude Code,
+Claude Desktop, etc.) provides the intelligence layer by reading schema notes via existing
+MCP tools.
+
+## Architecture
+

+
+No new database tables. Schemas are notes with `type: schema` — they're already indexed.
+Validation reads observations and relations from existing data.
+
+## Components
+
+### 1. Picoschema Parser
+
+**Location:** `src/basic_memory/schema/parser.py`
+
+Parses Picoschema YAML into an internal representation.
+
+```python
+@dataclass
+class SchemaField:
+    name: str
+    type: str                    # string, integer, number, boolean, any, or EntityName
+    required: bool               # True unless field name ends with ?
+    is_array: bool               # True if (array) notation
+    is_enum: bool                # True if (enum) notation
+    enum_values: list[str]       # Populated for enums
+    description: str | None      # Text after comma
+    is_entity_ref: bool          # True if type is capitalized (entity reference)
+    children: list[SchemaField]  # For (object) types
+
+
+@dataclass
+class SchemaDefinition:
+    entity: str                  # The entity type this schema describes
+    version: int                 # Schema version
+    fields: list[SchemaField]    # Parsed fields
+    validation_mode: str         # "warn" | "strict" | "off"
+    frontmatter_fields: list[SchemaField]  # From settings.frontmatter (default: [])
+
+
+def parse_picoschema(yaml_dict: dict) -> list[SchemaField]:
+    """Parse a Picoschema YAML dict into a list of SchemaField objects."""
+
+
+def parse_schema_note(frontmatter: dict) -> SchemaDefinition:
+    """Parse a full schema note's frontmatter into a SchemaDefinition."""
+```
+
+**Input/Output:**
+```yaml
+# Input (YAML dict from frontmatter)
+schema:
+  name: string, full name
+  role?: string, job title
+  works_at?: Organization, employer
+  expertise?(array): string, areas of knowledge
+```
+
+```python
+# Output
+[
+    SchemaField(name="name", type="string", required=True, description="full name", ...),
+    SchemaField(name="role", type="string", required=False, description="job title", ...),

+    SchemaField(name="expertise", type="string", required=False, is_array=True, ...),

+
+### 2. Schema Resolver
+
+**Location:** `src/basic_memory/schema/resolver.py`
+
+Finds the applicable schema for a note using the resolution order.
+
+```python
+async def resolve_schema(
+    note_frontmatter: dict,
+    search_fn: Callable,          # injected search capability
+) -> SchemaDefinition | None:
+    """Resolve schema for a note.

+    4. No schema (returns None)
+    """
+```
+
+### 3. Schema Validator
+
+**Location:** `src/basic_memory/schema/validator.py`

+
+### 4. Schema Inference Engine
+
+**Location:** `src/basic_memory/schema/inference.py`
+
+Analyzes notes of a given type and suggests a schema based on usage frequency.

+
+MCP tools call these endpoints via the typed client pattern (consistent with existing
+architecture).
+
+## Implementation Phases
+
+### Phase 1: Parser + Resolver
+
+Build the foundation — can parse Picoschema and find schemas for notes.
+
+**Deliverables:**
+- `schema/parser.py` — Picoschema YAML → `SchemaDefinition`
+- `schema/resolver.py` — Resolution order (inline → explicit ref → implicit by type → none)
+- Unit tests for all Picoschema syntax variations
+- Unit tests for resolution order
+
+**No external dependencies.** Pure Python parsing of YAML dicts. Can develop and test
+in isolation.
+
+### Phase 2: Validator
+
+Connect schemas to notes and produce validation results.
+
+**Deliverables:**
+- `schema/validator.py` — Validate note observations/relations against schema fields
+- API endpoint: `POST /schema/validate`
+- MCP tool: `schema_validate`
+- CLI command: `bm schema validate`
+- Integration tests with real notes and schemas
+
+**Depends on:** Phase 1 (parser + resolver)
+
+### Phase 3: Inference
+
+Analyze existing notes to suggest schemas.
+
+**Deliverables:**
+- `schema/inference.py` — Frequency analysis across notes of a type
+- API endpoint: `POST /schema/infer`
+- MCP tool: `schema_infer`
+- CLI command: `bm schema infer`
+- Option to save inferred schema as a note via `write_note`
+
+**Depends on:** Phase 1 (parser for output format)
+
+### Phase 4: Diff
+
+Compare schemas against current usage.
+
+**Deliverables:**
+- `schema/diff.py` — Drift detection between schema and actual notes
+- API endpoint: `GET /schema/diff/{entity_type}`
+- CLI command: `bm schema diff`
+
+**Depends on:** Phase 1 (parser), Phase 3 (inference, for frequency analysis)
+
+## Testing Strategy
+
+- **Unit tests** (`tests/schema/`): Parser edge cases, resolution logic, validation mapping,
+  inference thresholds
+- **Integration tests** (`test-int/schema/`): End-to-end with real markdown files, schema notes
+  on disk, CLI invocation
+- Coverage target: 100% (consistent with project standard)
+
+## What This Does NOT Include
+
+- No new database tables or migrations
+- No new markdown syntax (schemas validate existing observations/relations)
+- No LLM agent runtime or API key management
+- No hook integration (deferred)
+- No schema composition/inheritance (deferred)
+- No OWL/RDF export (deferred)
+- No built-in templates (deferred)

+# SPEC-SCHEMA: Basic Memory Schema System
+
+**Status:** Draft
+**Created:** 2025-02-06
+**Branch:** `feature/schema-system`
+
+## Summary
+
+A schema system for Basic Memory that uses [Picoschema](https://genkit.dev/docs/dotprompt/)
+syntax in YAML frontmatter. Schemas validate notes against their existing observation/relation
+structure — no new data model, no migration, just a declarative lens over what's already there.
+
+## Core Principles
+
+1. **Schemas are just notes** — A schema is a note with `type: schema`, lives anywhere
+2. **Use prior art** — Picoschema syntax in YAML frontmatter, no custom notation
+3. **Validation maps to existing format** — Observations and relations, not a parallel data model
+4. **Validation is soft** — Warnings by default, not blocking errors
+5. **Inference over prescription** — Schemas describe reality, emerge from usage
+6. **No built-in agent** — Programmatic core; the LLM already in the session provides intelligence
+
+## Picoschema Syntax
+
+Picoschema is a compact schema notation from Google's Dotprompt that fits naturally in YAML
+frontmatter.
+
+### Supported Types
+
+| Type | Description |
+|------|-------------|
+| `string` | Text value |
+| `integer` | Whole number |
+| `number` | Decimal number |
+| `boolean` | True/false |
+| `any` | Any scalar type |
+| `EntityName` | Reference to another entity (capitalized = entity reference) |
+
+### Syntax Rules
+
+```yaml
+schema:
+  name: string, full name                # required field with description
+  email?: string, contact email           # ? = optional
+  role?: string, job title
+  works_at?: Organization, employer       # capitalized type = entity reference
+  tags?(array): string, categories        # array of type
+  status?(enum): [active, inactive]       # enum with allowed values
+  metadata?(object):                      # nested object
+    updated_at?: string
+    source?: string
+```
+
+- `field: type` — required field
+- `field?: type` — optional field
+- `field(array): type` — array of values
+- `field?(enum): [values]` — enumeration
+- `field?(object):` — nested object with sub-fields
+- `, description` — description after comma
+- `EntityName` as type (capitalized) — reference to another entity
+
+## Schema-to-Note Mapping
+
+Schemas validate against the existing Basic Memory note format. No new syntax for note
+authors to learn.
+
+### Mapping Rules
+
+| Schema Declaration | Grounded In | Example Match |
+|--------------------|-------------|---------------|
+| `field: string` | Observation `[field] value` | `- [name] Paul Graham` |
+| `field?(array): string` | Multiple `[field]` observations | `- [expertise] Lisp` (×N) |
+| `field?: EntityType` | Relation `field [[Target]]` | `- works_at [[Y Combinator]]` |
+| `field?(array): EntityType` | Multiple `field` relations | `- authored [[Book]]` (×N) |
+| `tags` | Frontmatter `tags` array | `tags: [startups, essays]` |
+| `field?(enum): [values]` | Observation `[field] value` where value ∈ set | `- [status] active` |
+| `settings.frontmatter` field | Frontmatter key presence/value | `tags: [python, ai]` |
+
+### Key Insight
+
+Schemas don't introduce a new way to store data. They describe the patterns already present
+in observations and relations. A note doesn't have to change how it's written — the schema
+just says "a good Person note has a `[name]` observation and a `works_at` relation."
+
+## Schema Definition
+
+### As a Dedicated Schema Note
+
+```yaml
+# schema/Person.md
+---
+title: Person
+type: schema
+entity: Person
+version: 1
+schema:
+  name: string, full name
+  email?: string, contact email
+  role?: string, job title
+  works_at?: Organization, employer
+  expertise?(array): string, areas of knowledge
+settings:
+  validation: warn    # warn | strict | off
+  frontmatter:
+    tags?(array): string, note categories
+    status?(enum): [draft, review, published]
+---
+
+# Person
+
+A human individual in the knowledge graph.
+
+Any documentation about this entity type goes here as prose.
+```
+
+Schema notes are regular Basic Memory notes. They show up in search, can have their own
+observations and relations, and can be organized in any folder (though `schema/` is
+the suggested convention).
+
+### Inline Schema in a Note
+
+Notes can carry their own schema directly:
+
+```yaml
+# meetings/2024-01-15-standup.md
+---
+title: Team Standup 2024-01-15
+type: meeting
+schema:
+  attendees(array): string, who was there
+  decisions(array): string, what was decided
+  action_items(array): string, follow-ups
+  blockers?(array): string, anything stuck
+---
+
+# Team Standup 2024-01-15
+
+## Observations
+- [attendees] Paul
+- [attendees] Sarah
+- [decisions] Ship v2 by Friday
+- [action_items] Paul to review PR #42
+- [blockers] Waiting on API credentials
+```
+
+Good for one-off structured notes or prototyping a schema before extracting it.
+
+### Explicit Schema Reference
+
+A note can reference a schema by entity name or permalink:
+
+```yaml
+# projects/basic-memory.md
+---
+title: Basic Memory
+schema: SoftwareProject         # by entity name
+---
+
+# research/llm-memory-patterns.md
+---
+title: LLM Memory Patterns
+schema: schema/research-project  # by permalink
+---
+```
+
+Use cases:
+- Note's `type` differs from the schema it should validate against
+- Multiple schema variants exist for the same domain
+- Applying structure to existing notes without changing their type
+
+## Schema Resolution
+
+When validating a note, schemas resolve in priority order:
+
+```
+1. Inline schema     →  schema: { ... }        (dict in frontmatter)
+2. Explicit ref      →  schema: Person          (string in frontmatter)
+3. Implicit by type  →  type: Person            (lookup schema note with entity: Person)
+4. No schema         →  no validation           (perfectly fine)
+```
+
+```python
+async def resolve_schema(note: Note) -> Schema | None:
+    schema_value = note.frontmatter.get('schema')
+
+    # 1. Inline schema (dict)
+    if isinstance(schema_value, dict):
+        return parse_picoschema(schema_value)
+
+    # 2. Explicit reference (string)
+    if isinstance(schema_value, str):
+        schema_note = await find_schema_note(schema_value)
+        if schema_note:
+            return parse_picoschema(schema_note.frontmatter['schema'])
+
+    # 3. Implicit by type
+    note_type = note.frontmatter.get('type')
+    if note_type:
+        results = await search_notes(f"type:schema entity:{note_type}")
+        if results:
+            return parse_picoschema(results[0].frontmatter['schema'])
+
+    # 4. No schema
+    return None
+```
+
+## Validation
+
+### Modes
+
+Configured in the schema's `settings.validation`:
+
+| Mode | Behavior |
+|------|----------|
+| `off` | No validation |
+| `warn` | Warnings in output, doesn't block (default) |
+| `strict` | Errors that block sync, for CI/CD enforcement |
+
+### Validation Output
+
+For a note missing required fields:
+
+```
+$ bm schema validate people/ada-lovelace.md
+
+⚠ Person schema validation:
+  - Missing required field: name (expected [name] observation)
+  - Missing optional field: role
+  - Missing optional field: works_at (no relation found)
+
+ℹ Unmatched observations: [fact] ×2, [born] ×1
+ℹ Unmatched relations: collaborated_with
+```
+
+"Unmatched" items are informational — observations and relations the schema doesn't cover.
+They're valid. Schemas are a subset, not a straitjacket.
+
+### Frontmatter Validation
+
+Schema notes can declare validation rules for frontmatter keys under `settings.frontmatter`
+using the same Picoschema syntax as the `schema` block:
+
+```yaml
+settings:
+  validation: warn
+  frontmatter:
+    tags?(array): string
+    status?(enum): [draft, review, published]
+```
+
+- Frontmatter rules use the same Picoschema key syntax (`?` for optional, `(enum)`, `(array)`)
+- Only available on schema notes (inline schemas skip frontmatter validation)
+- Checks key presence (required vs optional) and enum value membership
+- Unmatched frontmatter keys not in the schema are silently ignored
+- Missing required frontmatter keys produce a warning (or error in strict mode)
+
+Example output for a missing required frontmatter key:
+
+```
+⚠ Person schema validation:
+  - Missing required frontmatter key: status
+```
+
+### Batch Validation
+
+```
+$ bm schema validate Person
+
+Validating 30 notes against Person schema...
+
+✓ people/paul-graham.md         — all fields present
+✓ people/rich-hickey.md         — all fields present
+⚠ people/ada-lovelace.md        — missing: name
+⚠ people/alan-kay.md            — missing: name, role
+✓ people/linus-torvalds.md      — all fields present
+...
+
+Summary: 22/30 valid, 8 warnings, 0 errors
+```
+
+## Emerging Schemas
+
+### The Problem with Traditional Schemas
+
+Most schema systems require: define schema → create conforming content → fight the schema
+when reality doesn't match. This is backwards. Knowledge grows organically.
+
+### The Basic Memory Approach
+
+```
+Write notes freely → Patterns emerge → Crystallize into schema → Validate future notes
+```
+
+### Schema Inference
+
+Generate schemas from existing notes by analyzing observation and relation frequency:
+
+```
+$ bm schema infer Person
+
+Analyzing 30 notes with type: Person...
+
+Observations found:
+  [name]        30/30  100%  → name: string
+  [role]        27/30   90%  → role?: string
+  [fact]        25/30   83%  (generic — no single field)
+  [expertise]   18/30   60%  → expertise?(array): string
+  [email]        8/30   27%  → email?: string
+  [born]         6/30   20%  (below threshold)
+
+Relations found:
+  works_at      22/30   73%  → works_at?: Organization
+  authored      11/30   37%  → authored?(array): string
+
+Suggested schema:
+  name: string, full name
+  role?: string, job title
+  expertise?(array): string, areas of knowledge
+  email?: string, contact email
+  works_at?: Organization, employer
+
+Save to schema/Person.md? [y/n]
+```
+
+Frequency thresholds:
+- 100% present → required field
+- 25%+ present → optional field
+- Below 25% → excluded from suggestion (but noted)
+
+### Schema Drift Detection
+
+Track how usage patterns shift over time:
+
+```
+$ bm schema diff Person
+
+Schema drift detected:
+
++ expertise: now in 81% of notes (was 12%)
+- department: dropped to 3% of notes
+~ works_at: cardinality changed (one → many)
+
+Update schema? [y/n/review]
+```
+
+## LLM Integration (AI Guidance)
+
+No agent runtime or API key required. The LLM already in the session uses schemas as
+context for note creation.
+
+### Flow
+
+1. User asks LLM to "write a note about Rich Hickey"
+2. LLM determines `type: Person` is appropriate
+3. LLM calls `search_notes("type:schema entity:Person")` → finds schema
+4. LLM reads schema fields: required `name`, optional `role`, `works_at`, `expertise`
+5. LLM calls `write_note` with observations and relations that satisfy the schema
+
+The schema acts as a creation template. The LLM knows what a "complete" note looks like
+without any custom agent infrastructure.
+
+### MCP Tools
+
+```python
+@mcp_tool
+async def schema_validate(
+    entity_type: str | None = None,

+
+    Examines observation categories and relation types across all notes

+## CLI Commands
+
+```bash
+# Validate a specific note
+bm schema validate people/ada-lovelace.md
+
+# Validate all notes of a type

+## Examples
+
+### Complete Person Workflow
+
+**Schema:**
+```yaml
+# schema/Person.md
+---
+title: Person
+type: schema
+entity: Person
+version: 1
+schema:
+  name: string, full name
+  role?: string, job title or position
+  works_at?: Organization, employer
+  expertise?(array): string, areas of knowledge
+  email?: string, contact email
+settings:
+  validation: warn
+---
+
+# Person
+
+A human individual in the knowledge graph.
+```
+
+**Valid note:**
+```yaml
+# people/paul-graham.md
+---
+title: Paul Graham
+type: Person
+tags: [startups, essays, lisp]
+---
+
+# Paul Graham
+
+## Observations
+- [name] Paul Graham
+- [role] Essayist and investor
+- [expertise] Startups
+- [expertise] Lisp
+- [expertise] Essay writing
+- [fact] Created Viaweb, the first web app
+
+## Relations
+- works_at [[Y Combinator]]
+- authored [[Hackers and Painters]]
+```
+
+**Note with warnings:**
+```yaml
+# people/ada-lovelace.md
+---
+title: Ada Lovelace
+type: Person
+---
+
+# Ada Lovelace
+
+## Observations
+- [fact] Wrote the first computer program
+- [born] 1815
+
+## Relations
+- collaborated_with [[Charles Babbage]]
+```
+
+Validation: warns about missing required `[name]` observation. Everything else is optional
+or unmatched (which is fine).
+
+## Future Considerations (Deferred)
+
+These are interesting but out of scope for the initial implementation:
+
+- **Multiple schema inheritance** — `schema: [Person, Author]`
+- **Hook integration** — Pre-write validation via the hooks system
+- **OWL/RDF export** — `bm schema export --format owl`
+- **SPARQL queries** — Schema-aware graph queries
+- **Built-in templates** — `bm schema use gtd`, `bm schema use zettelkasten`
+- **Schema versioning/migration** — Tracking breaking changes across versions

+Basic Memory’s test suite intentionally mixes:
+- unit tests (fast, deterministic)
+- integration tests (real filesystem + real DB via `test-int/`)

+To keep the default CI signal **stable and meaningful**, the default `pytest` coverage report targets **core library logic** and **excludes** a small set of modules that are either:
+- highly environment-dependent (OS/DB tuning)
+- inherently interactive (CLI)
+- background-task orchestration (watchers/sync runners)
+
+### What's excluded (and why)
+
+Coverage excludes are configured in `pyproject.toml` under `[tool.coverage.report].omit`.
+
+Current exclusions include:
+- `src/basic_memory/cli/**`: interactive wrappers; behavior is validated via higher-level tests and smoke tests.
+- `src/basic_memory/db.py`: platform/backend tuning paths (SQLite/Postgres/Windows), covered by integration tests and targeted runs.
+- `src/basic_memory/services/initialization.py`: startup orchestration/background tasks; covered indirectly by app/MCP entrypoints.
+- `src/basic_memory/sync/sync_service.py`: heavy filesystem↔DB integration; validated in integration suite (not enforced in unit coverage).
+
+### Recommended additional runs
+
+If you want extra confidence locally/CI:
+- **Postgres backend**: run tests with `BASIC_MEMORY_TEST_POSTGRES=1`.
+- **Strict backend-complete coverage**: run coverage on SQLite + Postgres and combine the results (recommended).

-# SPEC-1: Specification-Driven Development Process
-
-## Why
-We're implementing specification-driven development to solve the complexity and circular refactoring issues in our web development process. 
-Instead of getting lost in framework details and type gymnastics, we start with clear specifications that drive implementation.
-
-The default approach of adhoc development with AI agents tends to result in:
-- Circular refactoring cycles
-- Fighting framework complexity
-- Lost context between sessions
-- Unclear requirements and scope
-
-## What
-This spec defines our process for using basic-memory as the specification engine to build basic-memory-cloud. 
-We're creating a recursive development pattern where basic-memory manages the specs that drive the development of basic-memory-cloud.
-
-**Affected Areas:**
-- All future component development
-- Architecture decisions
-- Agent collaboration workflows
-- Knowledge management and context preservation
-
-## How (High Level)
-
-### Specification Structure
-
-Name: Spec names should be numbered sequentially, followed by a description eg. `SPEC-X - Simple Description.md`.
-See: [[Spec-2: Slash Commands Reference]]
-
-Every spec is a complete thought containing:
-- **Why**: The reasoning and problem being solved
-- **What**: What is affected or changed
-- **How**: High-level approach to implementation
-- **How to Evaluate**: Testing/validation procedure
-- Additional context as needed
-
-### Living Specification Format
-
-Specifications are **living documents** that evolve throughout implementation:
-
-**Progress Tracking:**
-- **Completed items**: Use ✅ checkmark emoji for implemented features
-- **Pending items**: Use `- [ ]` GitHub-style checkboxes for remaining tasks
-- **In-progress items**: Use `- [x]` when work is actively underway
-
-**Status Philosophy:**
-- **Avoid static status headers** like "COMPLETE" or "IN PROGRESS" that become stale
-- **Use checklists within content** to show granular implementation progress
-- **Keep specs informative** while providing clear progress visibility
-- **Update continuously** as understanding and implementation evolve
-
-**Example Format:**
-```markdown
-### ComponentName
-- ✅ Basic functionality implemented
-- ✅ Props and events defined
-- - [ ] Add sorting controls
-- - [ ] Improve accessibility
-- - [x] Currently implementing responsive design
-```
-
-This creates **git-friendly progress tracking** where `[ ]` easily becomes `[x]` or ✅ when completed, and specs remain valuable throughout the development lifecycle.
-
-
-## Claude Code 
-
-We will leverage Claude Code capabilities to make the process semi-automated. 
-
-- Slash commands: define repeatable steps in the process (create spec, implement, review, etc)
-- Agents: define roles to carry out instructions  (front end developer, baskend developer, etc)
-- MCP tools: enable agents to implement specs via actions (write code, test, etc)
-
-### Workflow
-1. **Create**: Write spec as complete thought in `/specs` folder
-2. **Discuss**: Iterate and refine through agent collaboration
-3. **Implement**: Hand spec to appropriate specialist agent
-4. **Validate**: Review implementation against spec criteria
-5. **Document**: Update spec with learnings and decisions
-
-### Slash Commands
-
-Claude slash commands are used to manage the flow.
-These are simple instructions to help make the process uniform. 
-They can be updated and refined as needed. 
-
-- `/spec create [name]` - Create new specification
-- `/spec status` - Show current spec states
-- `/spec implement [name]` - Hand to appropriate agent
-- `/spec review [name]` - Validate implementation
-
-### Agent Orchestration
-
-Agents are defined with clear roles, for instance:
-
-- **system-architect**: Creates high-level specs, ADRs, architectural decisions
-- **vue-developer**: Component specs, UI patterns, frontend architecture
-- **python-developer**: Implementation specs, technical details, backend logic
-- 
-- Each agent reads/updates specs through basic-memory tools. 
-
-## How to Evaluate
-
-### Success Criteria
-- Specs provide clear, actionable guidance for implementation
-- Reduced circular refactoring and scope creep
-- Persistent context across development sessions
-- Clean separation between "what/why" and implementation details
-- Specs record a history of what happened and why for historical context
-
-### Testing Procedure
-1. Create a spec for an existing problematic component
-2. Have an agent implement following only the spec
-3. Compare result quality and development speed vs. ad-hoc approach
-4. Measure context preservation across sessions
-5. Evaluate spec clarity and completeness
-
-### Metrics
-- Time from spec to working implementation
-- Number of refactoring cycles required
-- Agent understanding of requirements
-- Spec reusability for similar components
-
-## Notes
-- Start simple: specs are just complete thoughts, not heavy processes
-- Use basic-memory's knowledge graph to link specs, decisions, components
-- Let the process evolve naturally based on what works
-- Focus on solving the actual problem: Manage complexity in development
-
-## Observations
-
-- [problem] Web development without clear goals and documentation circular refactoring cycles #complexity
-- [solution] Specification-driven development reduces scope creep and context loss #process-improvement

-
-# SPEC-5: CLI Cloud Upload via WebDAV
-
-## Why
-
-Existing basic-memory users need a simple migration path to basic-memory-cloud. The web UI drag-and-drop approach outlined in GitHub issue #59, while user-friendly, introduces significant complexity for a proof-of-concept:
-
-- Complex web UI components for file upload and progress tracking
-- Browser file handling limitations and CORS complexity
-- Proxy routing overhead for large file transfers
-- Authentication integration across multiple services
-
-A CLI-first approach solves these issues by:
-
-- **Leveraging existing infrastructure**: Both cloud CLI and tenant API already exist with WorkOS JWT authentication
-- **Familiar user experience**: Basic-memory users are CLI-comfortable and expect command-line tools
-- **Direct connection efficiency**: Bypassing the MCP gateway/proxy for bulk file transfers
-- **Rapid implementation**: Building on existing `CLIAuth` and FastAPI foundations
-
-The fundamental problem is migration friction - users have local basic-memory projects but no path to cloud tenants. A simple CLI upload command removes this barrier immediately.
-
-## What
-
-This spec defines a CLI-based project upload system using WebDAV for direct tenant connections.
-
-**Affected Areas:**
-- `apps/cloud/src/basic_memory_cloud/cli/main.py` - Add upload command to existing CLI
-- `apps/api/src/basic_memory_cloud_api/main.py` - Add WebDAV endpoints to tenant FastAPI
-- Authentication flow - Reuse existing WorkOS JWT validation
-- File transfer protocol - WebDAV for cross-platform compatibility
-
-**Core Components:**
-
-### CLI Upload Command
-```bash
-basic-memory-cloud upload <project-path> --tenant-url https://basic-memory-{tenant}.fly.dev
-```
-
-### WebDAV Server Endpoints
-- `GET/PUT/DELETE /webdav/*` - Standard WebDAV operations on tenant file system
-- Authentication via existing JWT validation
-- File operations preserve timestamps and directory structure
-
-### Authentication Flow
-```
-1. User runs `basic-memory-cloud login` (existing)
-2. CLI stores WorkOS JWT token (existing)
-3. Upload command reads JWT from storage
-4. WebDAV requests include JWT in Authorization header
-5. Tenant API validates JWT using existing middleware
-```
-
-## How (High Level)
-
-### Implementation Strategy
-
-**Phase 1: CLI Command**
-- Add `upload` command to existing Typer app
-- Reuse `CLIAuth` class for token management
-- Implement WebDAV client using `webdavclient3` or similar
-- Rich progress bars for transfer feedback
-
-**Phase 2: WebDAV Server**
-- Add WebDAV endpoints to existing tenant FastAPI app
-- Leverage existing `get_current_user` dependency for authentication
-- Map WebDAV operations to tenant file system
-- Preserve file modification times using `os.utime()`
-
-**Phase 3: Integration**
-- Direct connection bypasses MCP gateway and proxy
-- Simple conflict resolution: overwrite existing files
-- Error handling: fail fast with clear error messages
-
-### Technical Architecture
-
-```
-basic-memory-cloud CLI → WorkOS JWT → Direct WebDAV → Tenant FastAPI
-                                                    ↓
-                                               Tenant File System
-```
-
-**Key Libraries:**
-- CLI: `webdavclient3` for WebDAV client operations
-- API: `wsgidav` or FastAPI-compatible WebDAV server
-- Progress: `rich` library (already imported in CLI)
-- Auth: Existing WorkOS JWT infrastructure
-
-### WebDAV Protocol Choice
-
-WebDAV provides:
-- **Cross-platform clients**: Native support in most operating systems
-- **Standardized protocol**: Well-defined for file operations
-- **HTTP-based**: Works with existing FastAPI and JWT auth
-- **Library support**: Good Python libraries for both client and server
-
-### POC Constraints
-
-**Simplifications for rapid implementation:**
-- **Known tenant URLs**: Assume `https://basic-memory-{tenant}.fly.dev` format
-- **Upload only**: No download or bidirectional sync
-- **Overwrite conflicts**: No merge or conflict resolution prompting
-- **No fallbacks**: Fail fast if WebDAV connection issues occur
-- **Direct connection only**: No proxy fallback mechanism
-
-## How to Evaluate
-
-### Success Criteria
-
-**Functional Requirements:**
-- [ ] Transfer complete basic-memory project (100+ files) in < 30 seconds
-- [ ] Preserve directory structure exactly as in source project
-- [ ] Preserve file modification timestamps for proper sync behavior
-- [ ] Rich progress bars show real-time transfer status (files/MB transferred)
-- [ ] WorkOS JWT authentication validates correctly on WebDAV endpoints
-- [ ] Direct tenant connection bypasses MCP gateway successfully
-
-**Quality Requirements:**
-- [ ] Clear error messages for authentication failures
-- [ ] Graceful handling of network interruptions
-- [ ] CLI follows existing command patterns and help text standards
-- [ ] WebDAV endpoints integrate cleanly with existing FastAPI app
-
-**Performance Requirements:**
-- [ ] File transfer speed > 1MB/s on typical connections
-- [ ] Memory usage remains reasonable for large projects
-- [ ] No timeout issues with 500+ file projects
-
-### Testing Procedure
-
-**Unit Testing:**
-1. CLI command parsing and argument validation
-2. WebDAV client connection and authentication
-3. File timestamp preservation during transfer
-4. JWT token validation on WebDAV endpoints
-
-**Integration Testing:**
-1. End-to-end upload of test project
-2. Direct tenant connection without proxy
-3. File integrity verification after upload
-4. Progress tracking accuracy during transfer
-
-**User Experience Testing:**
-1. Upload existing basic-memory project from local installation
-2. Verify uploaded files appear correctly in cloud tenant
-3. Confirm basic-memory database rebuilds properly with uploaded files
-4. Test CLI help text and error message clarity
-
-### Validation Commands
-
-**Setup:**
-```bash
-# Login to WorkOS
-basic-memory-cloud login
-
-# Upload project
-basic-memory-cloud upload ~/my-notes --tenant-url https://basic-memory-test.fly.dev
-```
-
-**Verification:**
-```bash
-# Check tenant health and file count via API
-curl -H "Authorization: Bearer $JWT" https://basic-memory-test.fly.dev/health
-curl -H "Authorization: Bearer $JWT" https://basic-memory-test.fly.dev/notes/search
-```
-
-### Performance Benchmarks
-
-**Target metrics for 100MB basic-memory project:**
-- Transfer time: < 30 seconds
-- Memory usage: < 100MB during transfer
-- Progress updates: Every 1MB or 10 files
-- Authentication time: < 2 seconds
-
-## Observations
-
-- [implementation-speed] CLI approach significantly faster than web UI for POC development #rapid-prototyping
-- [user-experience] Basic-memory users already comfortable with CLI tools #user-familiarity
-- [architecture-benefit] Direct connection eliminates proxy complexity and latency #performance
-- [auth-reuse] Existing WorkOS JWT infrastructure handles authentication cleanly #code-reuse
-- [webdav-choice] WebDAV protocol provides cross-platform compatibility and standard libraries #protocol-selection
-- [poc-scope] Simple conflict handling and error recovery sufficient for proof-of-concept #scope-management
-- [migration-value] Removes primary barrier for local users migrating to cloud platform #business-value

----
-
-# SPEC-6: Explicit Project Parameter Architecture
-
-## Why
-
-The current session-based project management system has critical reliability issues:
-
-1. **Session State Fragility**: Claude iOS mobile client fails to maintain consistent session IDs across MCP tool calls, causing project switching to silently fail (Issue #74)
-2. **Scaling Limitations**: Redis-backed session state creates single-point-of-failure and prevents horizontal scaling
-3. **Client Compatibility**: Session tracking works inconsistently across different MCP clients (web, mobile, API)
-4. **Hidden Complexity**: Users cannot see or understand "current project" state, leading to confusion when operations execute in wrong projects
-5. **Silent Failures**: Operations appear successful but execute in unintended projects, risking data integrity
-
-Evidence from production logs shows each MCP tool call from mobile client receives different session IDs:
-```
-create_memory_project: session_id=12cdfc24913b48f8b680ed4b2bfdb7ba
-switch_project:       session_id=050a69275d98498cbdd227cdb74d9740
-list_directory:       session_id=85f3483014af4136a5d435c76ded212f
-```
-

-
-Implementation Approach                                                                    
-
-- Each tool will directly accept the project parameter                             
-- Remove all calls to context-based project retrieval                              
-- Validate project exists before operations                                        
-- Clear error messages when project not found                                      
-- Backward compatibility: Initially keep optional parameter, then make required

-                                                                                                                             
-### Phase 1.5: Default Project Mode Enhancement
-
-#### Problem
-While the stateless architecture solves reliability issues, it introduces UX friction for single-project users (estimated 80% of usage) who must specify the project parameter in every tool call.
-
-#### Solution: Default Project Mode
-Add optional `default_project_mode` configuration that allows single-project users to have the simplicity of implicit project selection while maintaining the reliability of stateless architecture.
-
-#### Configuration
-```json
-{
-  "default_project": "main",
-  "default_project_mode": true  // NEW: Auto-use default_project when not specified
-}
-```
-
-#### Implementation Details
-1. **Config Enhancement** (`src/basic_memory/config.py`)
-   - Add `default_project_mode: bool = Field(default=False)`
-   - Preserves backward compatibility (defaults to false)
-
-2. **Project Resolution Logic** (`src/basic_memory/mcp/project_context.py`)
-   Three-tier resolution hierarchy:
-   - Priority 1: CLI `--project` constraint (BASIC_MEMORY_MCP_PROJECT env var)
-   - Priority 2: Explicit project parameter in tool call
-   - Priority 3: `default_project` if `default_project_mode=true` and no project specified
-
-3. **Assistant Guide Updates** (`src/basic_memory/mcp/resources/ai_assistant_guide.md`)
-   - Detect `default_project_mode` at runtime
-   - Provide mode-specific instructions to LLMs
-   - In default mode: "All operations use project 'main' automatically"
-   - In regular mode: Current project discovery guidance
-
-4. **Tool Parameter Handling** (all MCP tools)
-   - Make project parameter Optional[str] = None
-   - Add resolution logic: `project = project or get_default_project()`
-   - Maintain explicit project override capability
-
-#### Usage Modes Summary
-- **Regular Mode**: Multi-project users, assistant tracks project per conversation
-- **Default Project Mode**: Single-project users, automatic default project
-- **Constrained Mode**: CLI --project flag, locked to specific project
-
-#### Testing Requirements
-- Integration test for default_project_mode=true with missing parameters
-- Test explicit project override in default_project_mode
-- Test mode=false requires explicit parameters
-- Test CLI constraint overrides default_project_mode
-
-Phase 2: Testing & Validation
-
-8. Update Tests
-
-- [x] Modify all MCP tool tests to pass required project parameter
-- [x] Remove tests for deleted tools (switch_project, get_current_project)
-- [x] Add tests for project parameter validation
-- [x] **Complete: All 147 tests across 5 test files updated and passing**
-
-#### Enhanced recent_activity Response
-```json
-{
-  "recent_notes": [...],
-  "project_activity": {
-    "research-project": {
-      "operations": 5,
-      "last_used": "30 minutes ago",
-      "recent_folders": ["experiments", "findings"]
-    },
-    "work-notes": {
-      "operations": 2,
-      "last_used": "2 hours ago",
-      "recent_folders": ["meetings", "planning"]
-    }
-  },
-  "total_projects": 3
-}

-
-### Phase 2: Cloud Service Simplification (basic-memory-cloud repository)
-
-#### Remove Session Infrastructure
-1. Delete `apps/mcp/src/basic_memory_cloud_mcp/middleware/session_state.py`
-2. Delete `apps/mcp/src/basic_memory_cloud_mcp/middleware/session_logging.py`
-3. Update `apps/mcp/src/basic_memory_cloud_mcp/main.py`:
-   ```python
-   # Remove session middleware
-   # server.add_middleware(SessionStateMiddleware)
-
-   # Enable stateless HTTP
-   mcp = FastMCP(name="basic-memory-mcp", stateless_http=True)
-   ```
-
-#### Deployment Simplification
-1. Remove Redis from `fly.toml`
-2. Remove Redis environment variables
-3. Update health checks to not depend on Redis
-
-### Phase 3: Conversational Project Management
-
-#### Claude Behavior Pattern
-1. **Project Discovery**:
-   ```
-   Claude: Let me check your recent activity...
-   [calls recent_activity() - no project needed for discovery]
-
-   I see you've been working in:
-   - research-project (5 operations, 30 min ago)
-   - work-notes (2 operations, 2 hours ago)
-
-   Which project should I use for this operation?
-   ```
-
-2. **Context Maintenance**:
-   ```
-   User: Use research-project
-   Claude: Working in research-project.
-   [All subsequent operations use project="research-project"]
-   ```
-
-3. **Explicit Project Switching**:
-   ```
-   User: Check work-notes for that meeting summary
-   Claude: Let me search work-notes for the meeting summary.
-   [Uses project="work-notes" for specific operation]
-   ```
-

-# SPEC-7: POC to spike Tigris/Turso for local access to cloud data
-
-## Why
-
-Current basic-memory-cloud architecture uses Fly volumes for tenant file storage, which creates several limitations:
-
-1. **Storage Scalability**: Fly volumes require pre-provisioning and don't auto-scale with usage
-2. **Cost Model**: Volume pricing vs object storage pricing may be less favorable at scale
-3. **Local Development**: No way for users to mount their cloud tenant files locally for real-time editing
-4. **Multi-Region**: Volumes are region-locked, limiting global deployment flexibility
-5. **Backup/Disaster Recovery**: Object storage provides better durability and replication options
-
-The core insight is that Basic Memory requires POSIX filesystem semantics but could benefit from object storage durability and accessibility. By combining:
-- **Tigris object storage** for file persistence (via rclone mount)
-- **Turso/libSQL** for SQLite indexing (replacing local .db files)
-
-We could enable a revolutionary user experience: **local editing of cloud-stored files** while maintaining Basic Memory's existing filesystem assumptions.
-
-## What
-
-This specification defines a proof-of-concept to validate the technical feasibility of the Tigris/Turso architecture for basic-memory-cloud tenants.
-
-**Affected Areas:**
-- **Storage Architecture**: Replace Fly volumes with Tigris object storage
-- **Database Architecture**: Replace local SQLite with Turso remote database
-- **Container Setup**: Add rclone mounting in tenant containers
-- **Local Development**: Enable local mounting of cloud tenant data
-- **Basic Memory Core**: Validate unchanged operation over mounted filesystems
-
-**Key Components:**
-- **Tigris Storage**: S3-compatible object storage via Fly.io integration
-- **rclone NFS Mount**: Native NFS mounting without FUSE dependencies
-- **Turso Database**: Hosted libSQL for SQLite replacement
-- **Single-Tenant Model**: One bucket + one database per tenant (simplified isolation)
-
-## How (High Level)
-
-### Phase 1: Local POC Validation
-- [ ] Set up Tigris bucket with test data
-- [ ] Configure rclone NFS mount locally
-- [ ] Test Basic Memory operations over mounted filesystem
-- [ ] Measure performance characteristics and identify issues
-- [ ] Validate file watching, sync operations, and concurrent access patterns
-
-### Phase 2: Database Migration
-- [ ] Set up Turso account and test database
-- [ ] Modify Basic Memory to accept external DATABASE_URL
-- [ ] Test all operations with remote SQLite via Turso
-- [ ] Validate performance and functionality parity
-
-### Phase 3: Container Integration
-- [ ] Create container image with rclone + NFS support
-- [ ] Implement tenant-specific credential management
-- [ ] Test container startup with automatic mounting
-- [ ] Validate isolation between tenant containers
-
-### Phase 4: Local Access Validation
-- [ ] Test local rclone mounting of tenant data
-- [ ] Validate real-time file editing experience
-- [ ] Test conflict resolution and sync behavior
-- [ ] Measure latency impact on user experience

-
-## How to Evaluate
-
-### Success Criteria
-- [ ] **Filesystem Compatibility**: Basic Memory operates without modification over rclone-mounted Tigris storage
-- [ ] **Performance Acceptable**: File operations complete within 2x local filesystem latency
-- [ ] **Database Functionality**: All Basic Memory features work with Turso remote SQLite
-- [ ] **Container Reliability**: Tenant containers start successfully with automatic mounting
-- [ ] **Local Access**: Users can mount and edit cloud files locally with real-time sync
-- [ ] **Data Isolation**: Tenant data remains properly isolated using bucket/database separation
-
-### Testing Procedure
-1. **Local Filesystem Test**:
-   ```bash
-   # Mount Tigris bucket locally
-   rclone nfsmount tigris:test-bucket ~/tigris-test --vfs-cache-mode writes
-
-   # Run Basic Memory operations
-   cd ~/tigris-test && basic-memory sync --watch
-   # Test: create notes, search, file watching, bulk operations
-   ```
-
-2. **Database Migration Test**:
-   ```bash
-   # Configure Turso connection
-   export DATABASE_URL="libsql://test-db.turso.io?authToken=..."
-
-   # Test all MCP tools with remote database
-   basic-memory tools # Test each tool functionality
-   ```
-
-3. **Container Integration Test**:
-   ```dockerfile
-   # Test container with rclone mounting
-   FROM python:3.12
-   RUN apt-get update && apt-get install -y rclone nfs-common
-   # ... test startup and mounting process
-   ```
-
-4. **Performance Benchmarking**:
-   - File creation/read/write operations (target: <2x local latency)
-   - Search query performance (target: comparable to local SQLite)
-   - File watching responsiveness (target: events within 1-2 seconds)
-   - Concurrent operation handling
-
-### Risk Assessment
-**High Risk Items**:
-- [ ] NFS-over-S3 performance may be insufficient for real-time operations
-- [ ] File watching (`inotify`) over NFS may be unreliable
-- [ ] Network interruptions could cause filesystem errors
-- [ ] Concurrent access patterns might hit S3 rate limits
-
-**Mitigation Strategies**:
-- Comprehensive performance testing before committing to architecture
-- Fallback plan to S3-native storage backend if filesystem approach fails
-- Extensive error handling and retry logic for network issues
-
-### Metrics to Track
-- **Latency**: File operation response times (read/write/watch)
-- **Reliability**: Success rate of file operations over time
-- **Throughput**: Concurrent file operations and search queries
-- **User Experience**: Perceived performance for local mounting use case
-
-## Notes
-
-### Key Architectural Decisions
-- **Single tenant per bucket/database**: Simplifies isolation and credential management
-- **Maintain POSIX compatibility**: Preserve Basic Memory's existing filesystem assumptions
-- **NFS over FUSE**: Better compatibility and performance characteristics
-- **Turso for SQLite**: Leverages specialized remote SQLite expertise
-
-### Alternative Approaches Considered
-- **S3-native storage backend**: Would require Basic Memory architecture changes
-- **Hybrid approach**: Local files + cloud sync (adds complexity)
-- **FUSE mounting**: More platform dependencies and kernel requirements
-
-### Integration Points
-- [ ] Fly.io Tigris integration for bucket provisioning
-- [ ] Turso account setup and database provisioning
-- [ ] Container image modifications for rclone support
-- [ ] Credential management for tenant isolation
-
-## Observations
-
-- [architecture] Tigris/Turso split cleanly separates file storage from indexing concerns #storage-separation
-- [user-experience] Local mounting of cloud files could be revolutionary for knowledge management #local-cloud-hybrid
-- [compatibility] Maintaining POSIX filesystem assumptions preserves Basic Memory's local/cloud compatibility #architecture-preservation
-- [simplification] Single tenant per bucket eliminates complex multi-tenancy in storage layer #tenant-isolation
-- [risk] NFS-over-S3 performance characteristics are unproven for real-time operations #performance-risk
-- [benefit] Object storage pricing model could be more favorable than volume pricing #cost-optimization
-- [innovation] Real-time local editing of cloud-stored files addresses major SaaS limitation #competitive-advantage

+- Stable external UUIDs that won't change with file moves or renames
+- Better API ergonomics with consistent string identifiers
+- Direct database lookups via unique indexed column
+- Simplified caching strategies
