New T7 block in lib/tests/run-reconcile.sh (+6 assertions, 20→26):
a throwaway git repo under mktemp with a LOCAL BARE origin drives the
3 previously-unexercised oracles live: tree_clean (dirty→rc≠0, clean→
rc0), pushed (pushed to origin FIRST so origin/main exists — else
rev-list is vacuously empty — then rc0 when synced, rc≠0 once 1 ahead),
msg_committed (rc0 for a present commit message, rc≠0 for an absent
one). Closes J4-12 (DEGRADED, prerequisite of SPEC-09/10): these 3
oracles backed report-only /reconcile output with zero test coverage —
a silent inversion would mis-report open-work state.
Mutation (lean scratch copy — only lib/reconcile.sh + lib/tests/
run-reconcile.sh + its fixtures + .claude/memory/decisions.md, not the
whole repo/.git, per the /tmp-exhaustion lesson from SPEC-01/02/04):
inverted tree_clean's rc (`-z` → `-n` on the porcelain-status check;
the report's literal "--quiet → negated" wording doesn't match this
function's actual `[ -z ... ]` shape, so applied the equivalent
semantic inversion). RED: both T7a assertions fail (dirty reads as
clean and vice versa); T7b/T7c stay green, confirming the mutation is
localized. (T6a/b/c red in the lean copy too, expected — no real git
history / skills dir there — unrelated to the mutation.)
GREEN: real repo unmutated, 26/26 passed (T7 included).
skills/reconcile/SKILL.md:53 claimed "20/20, shellcheck clean" but the
suite read .claude/memory/blockers.md live, so closing BLK-009
(d1e7423) turned T2b/T2c red for a correct reason unrelated to the
engine. Froze a post-BLK-009 snapshot (lib/tests/fixtures/
blockers-snapshot.md) and pointed T2 at it instead of the live file —
same approach the other T1/T3/T4 fixtures already use. Updated T2b/T2c
expectations to match (BLK-009 resolved, open = {001,003}). Suite is
back to 20/20 GREEN, shellcheck clean, matching the skill's own claim.
$MEM/../skills resolved to .claude/skills/ (the LRN-042 parasite, removed
2026-06-30 by make plugin Step 8.5), not the real skills/. Green at build
time only because the parasite still existed — green-for-wrong-reason
(LRN-077 class); red ever since. Suite back to 20/20.

/reconcile confronts declarative sources (TODO checkboxes, registry
statuses, ## Index) against real git/fs state and surfaces the gaps,
in 4 categories + contradiction candidates.
- lib/reconcile.sh: engine — body-only enumeration (never the Index),
git/fs oracles, BLK last-block-wins status, lexical deferral sweep,
contradiction candidates, pure reconcile_verdict kernel.
- lib/tests/run-reconcile.sh + fixtures (neutral-named): 20/20;
recursive-coherence T1 reds if the engine reads the Index (teeth).
- skills/reconcile/SKILL.md: thin orchestration + A/B/C write-back gate,
honest limits (lexical deferrals, contradictions surfaced not asserted).
- CLAUDE.md: Skill routing line.
Founding principle: never trust a declarative source as an oracle — the
skill practices what it preaches (tested). Built via writing-skills TDD.
