Foundation for the coupled-capitalize invariant (Frame 2): commit ONLY .claude/memory + .claude/tasks, never `git add -A`. Safety lives in the pathspec because automation removes the human diff review. Proven on real git behavior, not assumed: - T1/T2: dangling code (untracked or pre-staged) never embarked. - T2-bis: `git commit -- pathspec` takes the working tree, not a stale index. - T3 idempotent, T4 fail-closed on broken state, T5 TODO.md in scope. _changed_paths filters to paths with real changes: `git commit -- pathspec` aborts the whole commit on a no-match pathspec (e.g. empty .claude/tasks), unlike `git add` which tolerates it.

# memory-commit.sh — surgically commit ONLY .claude/memory + .claude/tasks.
|
|
#
|
|
# Used by the dev-flow capitalize step (and, later, the v2 Stop hook) to couple
|
|
# the memory commit to the flow. Safety lives in the PATHSPEC, never in a human
|
|
# diff review — automation removes that review, so the scope must be airtight:
|
|
# code that happens to be dirty or staged is NEVER embarked.
|
|
#
|
|
# Usage (CLI):
|
|
# memory-commit.sh pending # exit 0 if memory/tasks have changes, 1 if clean
|
|
# memory-commit.sh commit "<message>" # surgical commit; exit 0 ok/no-op, 3 unsafe state
|
|
#
|
|
# Sourceable: `memory_pending` and `commit_memory` for the v2 hook.
