+description: Update the lifting-bits/sleigh repository for a new upstream Ghidra stable release. Use when bumping Ghidra stable tags or versions, porting or regenerating src/patches/stable from HEAD patches, updating Ghidra source or spec file lists, moving HEAD-only source/header entries into stable, validating local Ghidra builds, or preparing release-update commits and PRs.

+
+# Sleigh Ghidra Release
+
+## Overview
+
+Update this repository after NSA publishes a new Ghidra release. Prefer the repo's existing release-update shape: verify the upstream tag, reuse `src/ghidra-stable`, regenerate stable patches mechanically from HEAD patches where possible, update CMake lists, and validate with a local build.
+
+Read [references/release-checklist.md](references/release-checklist.md) when doing the update; it contains the detailed checklist and decision points.
+
+## Workflow
+
+1. Inspect state before changing anything:
+   - Run `git status --short`.
+   - Treat existing edits and untracked files as user-owned unless the task clearly says otherwise.
+   - Keep unrelated files out of release-update commits.
+
+2. Verify the target release:
+   - Use official upstream sources for release and tag facts.
+   - Prefer Exa MCP tools for web lookup when available.
+   - Confirm the tag format, usually `Ghidra_<version>_build`.
+
+3. Prepare `src/ghidra-stable`:
+   - Use the existing checkout when present.
+   - If a clone is needed, clone under `src/`.
+   - Normalize `origin` to HTTPS if the remote uses a local SSH alias:
+
+```bash
+git -C src/ghidra-stable remote set-url origin https://github.com/NationalSecurityAgency/ghidra.git
+```
+
+   - Fetch and check out the release tag:
+
+```bash
+git -C src/ghidra-stable fetch origin tag Ghidra_<version>_build --depth=1
+git -C src/ghidra-stable checkout --detach Ghidra_<version>_build
+git -C src/ghidra-stable config user.name "github-actions[bot]"
+git -C src/ghidra-stable config user.email "41898282+github-actions[bot]@users.noreply.github.com"
+```
+
+4. Regenerate stable patches mechanically:
+   - Start from a clean `Ghidra_<version>_build` checkout.
+   - Try applying HEAD patches in order.
+   - If a HEAD patch fails, inspect whether it is already upstreamed, still needed with adjusted context, or only applies to HEAD-only code. Abort and retry with the applicable subset when needed.
+   - Use `format-patch` from `Ghidra_<version>_build..HEAD` to create the new stable patch files.
+   - Update `src/setup-ghidra-source.cmake` patch ordering to match the regenerated files.
+
+5. Update release metadata and lists:
+   - Set `ghidra_version` in `src/setup-ghidra-source.cmake`.
+   - Search for `sleigh_RELEASE_IS_HEAD`; move entries into stable when the release now contains those sources or headers.
+   - Update `src/spec_files_stable.cmake` from the release checkout's `.slaspec` inventory.
+   - Check `cmake/packaging.cmake` and reset `PACKAGE_VERSION` to `1` when the release cycle requires it.
+
+6. Validate the exact files CMake will use:
+   - Re-checkout the release tag in `src/ghidra-stable`.
+   - Apply `src/patches/stable/*.patch`.
+   - Configure with `FETCHCONTENT_SOURCE_DIR_GHIDRASOURCE` pointing at the local checkout.
+   - Build with `cmake --build ... --parallel`.
+   - Run `ctest`; if no developer-mode configure was used, `No tests were found` may be expected.
+
+7. Review and commit only when asked:
+   - Use `git diff --cached --stat`, `git diff --cached --name-status`, and `git diff --cached --check`.
+   - `git diff --check` may flag generated `git format-patch` signature lines; inspect before changing generated patch files.
+   - Commit messages must follow the repo's 50/72 rule.

+# Release Update Checklist
+
+This checklist is based on the repository wiki page:
+https://github.com/lifting-bits/sleigh/wiki/New-Ghidra-Release-Update-Checklist
+
+## Files To Check
+
+- `src/setup-ghidra-source.cmake`: stable version, stable patch list, HEAD pin, source lists.
+- `src/patches/stable/`: regenerated patches for the stable Ghidra tag.
+- `src/patches/HEAD/`: source patches to port to the new stable release.
+- `src/spec_files_stable.cmake`: stable `.slaspec` inventory.
+- `src/spec_files_HEAD.cmake`: comparison point for new spec files.
+- `CMakeLists.txt`: public Ghidra headers copied into the build include directory.
+- `cmake/packaging.cmake`: package version reset when relevant.
+
+## Patch Regeneration
+
+Preferred pattern:
+
+```bash
+git -C src/ghidra-stable checkout --detach Ghidra_<version>_build
+git -C src/ghidra-stable am --ignore-space-change --ignore-whitespace --no-gpg-sign \
+  /absolute/path/to/src/patches/HEAD/*.patch
+git -C src/ghidra-stable format-patch -o /private/tmp/sleigh-ghidra-stable-patches \
+  Ghidra_<version>_build..HEAD
+```
+
+If a patch fails:
+
+- Run `git -C src/ghidra-stable am --abort`.
+- Inspect the failed patch and the target source.
+- Decide whether the patch is already upstreamed, still needed with refreshed context, or only applicable to HEAD-only code.
+- Reapply the exact applicable patch sequence or subset.
+- Regenerate stable patches from the resulting commits; avoid hand-editing patch bodies unless conflict resolution requires it.
+
+## Source And Header Lists
+
+Find HEAD-only gates:
+
+```bash
+rg -n "sleigh_RELEASE_IS_HEAD|sleigh_RELEASE_TYPE.*HEAD" \
+  CMakeLists.txt src cmake support tests
+```
+
+When a previously HEAD-only file exists in the new stable release, move it to the normal stable list and leave no dead conditional branch unless the branch still has a purpose.
+
+## Spec Files
+
+Build the stable inventory from the release checkout:
+
+```bash
+fd -e slaspec . src/ghidra-stable/Ghidra/Processors
+```
+
+Update `src/spec_files_stable.cmake` with sorted
+`${ghidrasource_SOURCE_DIR}/...` entries. Compare against both the old stable
+list and `src/spec_files_HEAD.cmake`.
+
+## Validation
+
+Verify the generated stable patch files directly:
+
+```bash
+git -C src/ghidra-stable checkout --detach Ghidra_<version>_build
+git -C src/ghidra-stable am --ignore-space-change --ignore-whitespace --no-gpg-sign \
+  /absolute/path/to/src/patches/stable/*.patch
+```
+
+Then configure and build Sleigh against the local checkout:
+
+```bash
+cmake -B build/ghidra-<version>-local -S . \
+  -DFETCHCONTENT_SOURCE_DIR_GHIDRASOURCE=/absolute/path/to/src/ghidra-stable
+cmake --build build/ghidra-<version>-local --parallel
+ctest --test-dir build/ghidra-<version>-local --output-on-failure
+```
+
+If tests matter for the update, use a developer-mode preset or option. A plain configure may not register tests.
