The code fix was already committed and every real test passed (packages/shared 68/68, apps/web 656/656). The only failure was in apps/api: release-gate-matrix.test.mjs → generated-appendix-differs-from-register.

Fix: gitreins t629 tier1 FAIL — stale generated appendix (generated-appendix-differs-from-register)

TL;DR

The code fix was already committed and every real test passed (packages/shared 68/68, apps/web 656/656). The only failure was in apps/api: release-gate-matrix.test.mjs → generated-appendix-differs-from-register.

This is not a code regression. The generated artifacts (disposition register appendix + gate-matrix pack) were regenerated before the task-close rows 52822758 and a848bba5 were appended to the board. At judge time the canonical event log had moved on, so the checked-in appendix was stale relative to the register. The docs-only commit under evaluation touched none of these files, so it inherited a tree-state ordering defect from the previous tick.

Fix: re-run the regen chain after all board appends, confirm the appendix diff is exactly the completion flips of the rows closed that tick, commit it, then judge the settled tree.

1. Root-cause analysis

1.1 The invariant that was violated

The disposition register is the canonical source of truth. The generated appendix and the gate-matrix pack are derived artifacts. For the release-gate check to be stable, this ordering must hold:

board appends (task-close events)  ->  regen derived artifacts  ->  commit  ->  judge

The failing tick violated it. The sequence was effectively:

regen derived artifacts  ->  commit code fix  ->  board appends (52822758, a848bba5)  ->  judge

So the board/register gained two completion events after the last regeneration. The appendix still described the pre-close state, and generated-appendix-differs-from-register fired because it diffs the generated appendix against the current register.

1.2 Why the failure is misleading

Together these prove the failure is a tree-state ordering artifact, not a behavioral regression introduced by the diff being evaluated. A judge that does not distinguish "diff caused it" from "diff inherited a dirty derived-state tree" will flag the wrong change.

1.3 The two specific events

Row id Event Landed after
52822758 task-close last artifact regen
a848bba5 task-close last artifact regen

Both are completion flips that the appendix must reflect. Because they landed late, the appendix's expected diff never included them.

2. Exact fix

Run the regen chain after every board append in the tick, on the same working tree. Do not reorder the steps.

2.1 Regen chain (the remedy that worked)

# 0. Preconditions: all board appends for this tick are already done.
#    Confirm the board is settled (no inline editor / pending write).
git status --porcelain

# 1. Regenerate the disposition register appendix from canonical events.
python3 scripts/gen-disposition-register.py --write

# 2. Validate it against the register (this is what the gate test checks).
python3 scripts/gen-disposition-register.py --validate

# 3. Regenerate the gate-matrix pack.
node scripts/release-gate-matrix.mjs

# 4. Inspect the appendix diff. It MUST contain exactly the completion flips
#    of the rows closed this tick (here: 52822758 and a848bba5) and nothing else.
git --no-pager diff -- \
  docs/disposition-register-appendix.md \
  release-gate-matrix.pack.json

# 5. Commit ONLY the regenerated artifacts.
git add docs/disposition-register-appendix.md release-gate-matrix.pack.json
git commit -m "chore(regenerate): refresh disposition appendix + gate-matrix after task-close 52822758, a848bba5"

# 6. Judge the settled tree.
gitreins task complete

Adjust the exact artifact paths in step 4/5 to your repo layout (docs/..., reports/..., etc.). The invariant — board appends before regen — is the part that matters.

2.2 Verifying the diff is "only completion flips"

The appendix diff should be additive-only for the closed rows. A useful check:

# Show only the row ids touched by the appendix diff.
git --no-pager diff -U0 -- docs/disposition-register-appendix.md \
  | grep -E '^[+-]' \
  | grep -vE '^(\+\+\+|---)' \
  | grep -oE '(52822758|a848bba5)' | sort -u

Expected output is exactly:

52822758
a848bba5

If the diff touches any other row, stop: a stale regen has been mixed with unrelated changes, and you should reset the derived files and redo steps 1–3.

2.3 Guardrail for future ticks (prevention)

Add a pre-judge check so this class of failure can never reach the gate. Put it at the top of the tick-completion path, before gitreins task complete:

#!/usr/bin/env bash
# scripts/prejudge-board-freshness.sh
# Fail if the board was appended after the last derived-artifact regen.
set -euo pipefail

REGISTER_LOG="${REGISTER_LOG:-.eduos/disposition-register.jsonl}"
APPENDIX="${APPENDIX:-docs/disposition-register-appendix.md}"

if [ ! -f "$REGISTER_LOG" ] || [ ! -f "$APPENDIX" ]; then
  echo "prejudge: missing register log or appendix; run the regen chain first" >&2
  exit 1
fi

# Newest board append vs. newest regen commit touching the appendix.
last_append=$(git log -1 --format=%ct -- "$REGISTER_LOG" 2>/dev/null || echo 0)
last_regen=$(git log -1 --format=%ct -- "$APPENDIX" 2>/dev/null || echo 0)

if [ "$last_append" -gt "$last_regen" ]; then
  echo "prejudge: board appends are newer than the generated appendix." >&2
  echo "  board:   $REGISTER_LOG  ($(date -d @$last_append 2>/dev/null || echo $last_append))" >&2
  echo "  regen:   $APPENDIX      ($(date -d @$last_regen 2>/dev/null || echo $last_regen))" >&2
  echo "  Run: python3 scripts/gen-disposition-register.py --write && --validate && node scripts/release-gate-matrix.mjs" >&2
  exit 1
fi

# Belt and braces: the generated output must equal the committed file.
python3 scripts/gen-disposition-register.py --validate
node scripts/release-gate-matrix.mjs --check

echo "prejudge: board is settled and derived artifacts are fresh"

Wire it in so it is impossible to judge a stale tree:

# .git/hooks/pre-commit (or the CI judge entrypoint), before completion
scripts/prejudge-board-freshness.sh

The ordering rule to encode in process docs:

Never judge a tree whose board was appended after its last regen.

3. Verification

The fix is considered verified when all of the following hold.

3.1 Targeted gate test passes

# From apps/api (or wherever the test lives)
node --test release-gate-matrix.test.mjs
# or the repo's runner:
pnpm --filter apps/api run test

Expected: generated-appendix-differs-from-register is gone; the suite passes.

3.2 Full workspace is green on the settled tree

pnpm -r run test

Expected, matching the original evidence baseline:

Package Result
packages/shared 68/68 pass
apps/web 656/656 pass
apps/api pass, including release-gate-matrix.test.mjs

3.3 The appendix diff contains exactly the two completion flips

git --no-pager diff --stat HEAD~1 -- docs/disposition-register-appendix.md release-gate-matrix.pack.json
git --no-pager diff -U0 HEAD~1 -- docs/disposition-register-appendix.md \
  | grep -E '^[+-]' | grep -vE '^(\+\+\+|---)' | grep -oE '(52822758|a848bba5)' | sort -u

Expected: only 52822758 and a848bba5 appear; no other row ids.

3.4 Reproduce the original failure to prove the diagnosis (optional but recommended)

# Simulate out-of-order state: regen, then append, without re-regen.
git checkout HEAD~1 -- docs/disposition-register-appendix.md release-gate-matrix.pack.json
node --test release-gate-matrix.test.mjs
# -> FAIL generated-appendix-differs-from-register

# Restore the fix
git checkout HEAD -- docs/disposition-register-appendix.md release-gate-matrix.pack.json
node --test release-gate-matrix.test.mjs
# -> PASS

If the second run passes while the first fails, the root cause (ordering, not code) is confirmed.

3.5 Judge acceptance

scripts/prejudge-board-freshness.sh   # exits 0
gitreins task complete                # succeeds on the settled tree

Item Value
Symptom tier1 FAIL on generated-appendix-differs-from-register while tier2 PASS
Misread as code regression in the docs-only commit under evaluation
Actual cause board task-closes 52822758/a848bba5 appended after the last artifact regen
Fix board appends → regen → commit → judge
Prevention prejudge-board-freshness.sh blocks judging a tree older than its board

Note: The repository itself was not present in this environment, so the paths above are parameterized to the layout described in the incident. The core script commands (gen-disposition-register.py --write/--validate, release-gate-matrix.mjs) reproduce the remedy exactly; adjust only the artifact paths in the diff/commit steps if your layout differs.
