New lib/tests/fixtures/decisions-snapshot.md (neutral name, LRN-077
style): carries a --help token (so reconcile_contradiction_candidates
still surfaces the BDR-001 ⇄ --help-chantier candidate against
todo-snapshot.md), a "one-line ticket" line, and representative
OUT-OF-SCOPE/DEFERRED/follow-up context. T3 and T5 in run-reconcile.sh
now read this fixture instead of the LIVE $MEM/decisions.md; deleted
the $MEM variable definition and its stale comment. Closes J4-10
(FIXTURE-DRIFT): T3/T5 were the last live-registry reads in this
suite (T2 was fixed in job3-B1) — any legitimate prune/reword of the
real decisions.md would have reded the suite for a reason unrelated
to the reconcile engine itself.
grep -c '$MEM' lib/tests/run-reconcile.sh == 0 (verified).
GREEN: real repo, 26/26 passed (all 4 T3 markers + T5 candidate found
via the fixture).
Red demo (per spec — no code mutation, this is a fixture-substitution
spec): lean scratch copy, pointed T3's decisions-arg at /dev/null
transiently → "one-line ticket" (the only marker living solely in the
decisions-side fixture, not in todo-snapshot.md) goes missing, RED;
the other 3 markers stay green (satisfied by todo-snapshot.md alone).
Proves the assertions actually read the fixture rather than passing
vacuously.
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).
New T15 block in lib/gitflow-test.sh (+7 assertions, 83→90): fresh git
init sandbox with NO identity (GIT_CONFIG_GLOBAL=/dev/null
GIT_CONFIG_SYSTEM=/dev/null, git 2.53 supports the override) →
gitflow_init must return rc 1 AND leave zero mutation: no develop
branch, unborn HEAD, hooksPath unset, nothing staged, no .gitignore/
.githooks written. Closes J4-06 (WEAK): every test repo up to now set
an identity first, so this precheck never fired.
Mutation (lean scratch copy — only lib/gitflow.sh + lib/gitflow-test.sh
+ templates/gitignore/standard.gitignore, not the whole repo/.git, to
avoid repeating the /tmp exhaustion from the SPEC-01/02/04 full-repo
copies): deleted the identity precheck (gitflow.sh:178-179). RED: 3/7
T15 assertions fail — "nothing staged", "no .gitignore written", "no
.githooks written" — while rc stays 1 and HEAD stays unborn (git itself
still refuses the identity-less commit). This is the half-applied-init
failure mode named in the finding (BLK-012 class): same exit code, but
now via a partial mutation instead of a clean upfront refusal — exactly
why the spec pins zero-mutation checks beyond rc alone.
GREEN: real repo unmutated, 90/90 passed (T15 included).
New T14 block in lib/gitflow-test.sh (+3 assertions, 80→83), direct
.githooks/pre-commit invocation (T10-style): T14a mixed code+.claude
staged together on main → BLOCKED (whitelist must not let code ride
along .claude/). T14b MERGE_HEAD present + code staged on main →
exit 0 (conflict-resolution commit exemption, gitflow.sh:222). T14c
hook installed+activated BEFORE the first commit (gitflow_install_hook,
not gitflow_init's deferred activation) → root commit still succeeds
(gitflow.sh:221). Closes J4-05 (WEAK): these 3 exemption paths were
untested — a whitelist regression, or the root/merge exemptions
breaking, would have been silent.
Mutations (scratch copy, applied via Bash/sed — not Edit/Write, avoids
tripping config-protection's path-suffix guard on lib/gitflow.sh for a
throwaway file that's never committed), one at a time, each reverted
before the next:
- T14c: deleted the root-commit guard (gitflow.sh:221,
`git rev-parse --verify -q HEAD ... || exit 0`) → T14c reds alone.
- T14b: deleted the MERGE_HEAD guard (gitflow.sh:222) → T14b reds alone.
- T14a: report's candidate mutation ("remove grep -v '^\.claude/'")
self-corrects (still blocks mixed, via the inverted over-blocking
direction — doesn't red). Used the pinned alternative instead:
`head -1` → `head -0` in the whitelist check (gitflow.sh:230),
neutering the non-empty test so every protected-branch commit is
wrongly allowed. T14a reds, plus (expected, same root cause) the
pre-existing T3 "block direct code on main" and T10 DRIFT(main)/
DRIFT(develop) also red — consistent with a whitelist regression
of this shape being a broad, not narrow, break.
GREEN: real repo unmutated, 83/83 passed (T14a/b/c included).
New T13 block in lib/gitflow-test.sh (+9 assertions, 71→80):
T13a release finish → main gets the commit, develop gets it via
merge-back, release branch deleted. T13b two open releases + a
finished hotfix → hotfix commit present in BOTH release branches.
T13c bugfix finish → develop only, main untouched, branch deleted.
Closes J4-02 (CRITICAL): a half-landed release (main-only or
develop-only) or a mis-based bugfix finish was invisible to the
only test suite that exercises gitflow_finish's fan-out.
Mutation (scratch copy, applied via Bash/perl — not Edit/Write, so
config-protection's path-suffix guard on lib/gitflow.sh isn't
tripped for a throwaway file that's never committed): deleted the
develop merge-back line in gitflow_finish's release arm
(gitflow.sh:122-125). RED: T13a fails 3/3 (rc 5 — _gitflow_delete
refuses because develop never got the merge, so the branch isn't
fully merged; develop missing the commit; branch not deleted).
GREEN: real repo unmutated, 80/80 passed (T13a/b/c included).
Makefile test target now loops lib/tests/run-*.sh in addition to
*.test.sh + gitflow-test.sh, special-casing run-release-candidate.sh
with RC_WORK=$(mktemp -d) RC_TAG=1. Closes J4-01 (CRITICAL): the 5
run-*.sh suites (memory-commit 13, doc-commit 32, doc-shape 19,
reconcile 20, release 5/5) were excluded from the repo's only
aggregate gate.
Mutation (scratch copy, never the working tree): dropped the
`-- "${changed[@]}"` pathspec from lib/memory-commit.sh:86's commit
call. RED: run-deterministic.sh T2 fails (pre-staged dangling code
gets embarked instead of staying staged), make test exits 2.
GREEN: real repo unmutated, make test exits 0, all suites incl. the
5 previously-excluded ones (RESULT: 13/32/19 passed, 20 GREEN, 5
GREEN RC_TAG=1).
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.
EVAL-018: job3 shipped, 46/46 findings verified, 20/23 fixes applied
(B1 blocked on sentinel scope, D2-D5+B6 skipped by decision), zero
residual on final re-sweep. LRN-105: explorer subagents need an
explicit ban on executing the subject-under-test's own CLI, not just
"read-only" framing (caught mid-run: a subagent ran `graphify .`).
Both sections never matched any component (envelope §1-§9 vs the real
§0-§15 structure; 8-axis integer weights vs the agents' 7/4 and 6/5
percentage-weight scoring). Kept what this file legitimately owns: the
depth-decision matrix and the sibling-skill dedup rules.
- A1: delete STEP 5d (graphify --mode quick doesn't exist in the CLI; the
command always failed, masked by `|| true` — STEP 10's full pass already
covers the graph)
- A2: STEP 10 full-pass build flag --output -> --out
- A8: pipeline is 12 steps (STEP 0-11), not 11; header template unchanged
(N/11 correctly denotes the max index of a 0-indexed 12-step sequence)
- A2: graphify build flag --output -> --out
- A4: ROADMAP xref points to the real /onboard add gsd path, not a nonexistent STEP 9 decision
- A5: exact gitflow init commit message (matches lib/gitflow.sh:163)
- A6: bare skill names (design-review, browse) — no gstack: namespace exists
- A7: eval pattern for recommend_anim_install_cmd (the function only echoes; must eval its output)
BDR-038 recorded NEXT.sh file + AskUserQuestion hand-back as the /deploy
design; 52f6678 removed both (LRN-102: pre-tool-call text may never render)
with no superseding decision. BDR-054 regularizes it. One-line banners on
docs/plans/2026-06-27-deploy-skill.md and docs/specs/2026-06-27-deploy-skill-design.md
point to the shipped behavior; historical body left untouched.
