-## Context
-Operator post-ex flow currently requires 3 separate commands, manual env export, and temp file creation for args. Goal: collapse to 1 command + 1 paste into Sliver, no env setup required.
-
-### Risks
-- sliver-client non-interactive mode uncertain — postex.sh explicitly avoids calling Sliver to sidestep this
-- Multi-version CRYSTAL_PALACE_HOME per engagement: .crystalenv is per-operator, env override always wins
-
-## Criteria
-- [x] ISC-1: Plan identifies every friction point in current post-ex flow
-- [x] ISC-2: Plan proposes single-command wrapper for DLL → PICO step
-- [x] ISC-3: Plan proposes inline args support (no temp file required)
-- [x] ISC-4: Plan proposes persistent config for CRYSTAL_PALACE_HOME
-- [x] ISC-5: Plan proposes idempotent extension install check
-- [x] ISC-6: Plan proposes named PICO output (not generic default)
-- [x] ISC-7: Plan specifies what scripts to change vs add
-- [x] ISC-8: Plan specifies backward-compatibility constraints
-
-## Decisions
-- postex.sh prints Sliver command rather than calling sliver-client directly — avoids non-interactive CLI uncertainty
-- .crystalenv is git-ignored per-operator — avoids committing engagement-specific paths
-- Named output default uses input DLL basename — human-readable, no timestamp churn during rapid iteration
