ci: restamp the MCP index in the release job so main stops going stale

[allxsmith]

Fixes the version-stamp race that went red on #518 and #520 today, on work unrelated to bestax-mcp in both cases.

The bug

scripts/gen-mcp-index.mjs:542 reads bulma-ui/package.json's version and writes it into the committed bestax-mcp/data/catalog.json as generatedFrom.version. CI gates that with gen:mcp:check (regenerate → git add --intent-to-add → git diff --exit-code).

A release breaks the invariant and nothing repairs it:

1. semantic-release pushes chore(release): 5.11.1 bumping bulma-ui/package.json.
2. Nothing in the release job regenerates catalog.json.
3. That commit skips CI, so no run on main ever evaluates gen:mcp:check.
4. Main now carries an index stamped 5.11.0. Every branch — existing or newly cut — regenerates to 5.11.1, diffs, and fails.

Two properties make it expensive out of proportion to its size. The failure lands on a file the PR never touched, so it reads as "my change broke something." And the one branch where the staleness lives is the one branch never checked, so main looks permanently green while being the source.

Worth correcting a common description of this: it is not a rebase problem. #520 was cut fresh from main after the release and still failed. Rebasing cannot help when main is where the stale file is.

The fix

A final step in the publish job that regenerates the index and commits any change back to main.

Why not @semantic-release/exec + a git asset, which is the shape this obviously wants: @semantic-release/git selects assets by running git ls-files -m -o and micromatching the output, and each release runs with working-directory set to its own package. Run from bulma-ui/, git ls-files lists only files under bulma-ui/, so bestax-mcp/data/catalog.json can never appear in that list whatever the asset path says. I probed this rather than trusting the docs:

$ cd bulma-ui && git ls-files -m -o | grep -c bestax-mcp
0

It would have committed nothing while looking correct — a fix that appears applied and is not, which is the worst outcome on offer.

That probe also found a pre-existing bug, left alone here but worth its own issue: bulma-ui/release.config.js lists pnpm-lock.yaml as a git asset, and the root lockfile is outside that cwd too, so that asset has never matched anything. Release commits silently never include lockfile changes.

Safety properties

• Runs last, after every publish has succeeded, so it cannot cost a release.
• Fails loudly. If the push fails the job goes red with packages already published — deliberately. That is the signal main needs a manual restamp, rather than a quiet return to the broken behaviour, and the ::error:: says exactly what to run.
• No-ops when nothing released. With no version change the generator's output is byte-identical and the guard exits early.
• permissions: unchanged (contents: read, id-token: write). The step authenticates with the App token in the remote URL — the same mechanism semantic-release uses, and necessary because the checkout runs persist-credentials: false, so there is no pushable credential in .git/config. GITHUB_TOKEN is not a ruleset bypass actor; the App is.
• No new actions, no SHA changes, no allowlist growth.

Verification

Both guard paths exercised on this branch:

state	guard	behaviour
against main's current stale index	diff detected	would git add + commit
after restamping	no diff	exits 0 early

The first row is not hypothetical — main is stale right now, so the drift branch ran against real conditions.

Full gate green (19/19, lint/format/storybook 0). Run with --concurrency=1 because this branch does not carry #520's sync-skills race fix; that flake is unrelated and tracked there.

Also included

One commit restamping the index for 5.11.1, repairing main's current state. #518 and #520 carry identical copies; whichever lands first makes the others no-ops.

Walkthrough

The PR updates the MCP catalog to @allxsmith/bestax-bulma version 5.11.1. The release workflow regenerates the catalog after publishing, skips unchanged output, and commits and pushes changes to main.

Changes

MCP catalog release flow

Layer / File(s)	Summary
Catalog version metadata bestax-mcp/data/catalog.json	The generated catalog records @allxsmith/bestax-bulma version 5.11.1.
Post-release catalog publication .github/workflows/ci.yml	The publish job regenerates the MCP index, skips commits when the output is unchanged, and commits signed changes with [skip ci] before pushing to main with the release App token. Push failures fail the job with remediation instructions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 02bda

The release workflow repairs the committed MCP index after publishing, but repository-owned generation runs while a push-capable App token is available; a compromised or malicious generator change could misuse that credential. The PR is mergeable with explicit security-owner awareness or follow-up to scope the token only to the push operation.

Deep review — 0 blocking · 3 advisory

#	Severity	Area	Finding	Location
1	🔵 Advisory	Robustness	Loud failure surfaces only as a red publish job on a main push, not a PR check — maintainers must watch main-branch workflow runs to catch a failed restamp (the ::error:: text is otherwise out-of-band).	.github/workflows/ci.yml:354
2	🔵 Advisory	Robustness	No concurrency: guard on the publish job; two near-simultaneous merges to main race. Pre-existing (semantic-release's own push non-ff's first), and the restamp inherits it rather than introducing it.	.github/workflows/ci.yml:176
3	🔵 Advisory	Robustness	Guard uses git diff --quiet -- bestax-mcp/data, which (unlike gen:mcp:check's add --intent-to-add) won't detect a brand-new untracked file under data/. Harmless for the version-stamp use case since releases never add component files, but it's a small divergence from the gate it mirrors.	.github/workflows/ci.yml:349

Overall: The change is sound and the diagnosis in the PR body checks out — a release bumps bulma-ui/package.json, gen-mcp-index.mjs:543 stamps that into the committed catalog.json, and nothing repaired it because the [skip ci] release commit never re-runs gen:mcp:check on main. The fix's load-bearing assumptions all hold: actions/checkout creates a local main branch, @semantic-release/git advances local HEAD before the restamp runs (so pnpm gen:mcp reads the bumped version), and git push HEAD:main is a fast-forward. The chore(bestax-mcp): … message clears commitlint (chore isn't a RELEASE_TYPES entry) and won't itself trigger a future bestax-mcp release. Both the check job and the restamp run on Node 24, so the restamped form matches what branches regenerate. The riskiest part is purely operational: if the final push fails, main stays stale exactly as before, only now with a red main-branch run as the signal — the human should confirm someone watches those runs.

Residual risk:

• Restamp push fails (perm/transient/non-ff) → main stays stale. Not refuted — it's the deliberate "fail loudly, manual restamp" trade-off (advisory 1). Bounded to the release run, and the ::error:: names the exact fix.
• Non-deterministic generator output between the restamp env and branch CI → drift persists in a new form. Refuted: gen:mcp:check (ci.yml:52) and the restamp both run on Node 24 with the same frozen lockfile, so the arbiter is consistent.
• Non-bulma-ui release (create-bestax / bestax-migrate / bestax-mcp) leaving the stamp stale. Refuted: catalog.json stamps only @allxsmith/bestax-bulma's version, so a non-bulma release yields byte-identical output and the guard correctly no-ops.

🏄 Clean little set wave, dude — spotted the rip current (release bumps the version, nobody restamps, main quietly goes gnarly on everyone downstream) and dropped in a tidy last-step cutback that pushes the fix right back to main. No blockers, just a couple of "keep an eye on the horizon" notes. Good to paddle out and merge. 🌊

Deep review handled — advisory 3 fixed in 02bda15, advisories 1 and 2 accepted with reasoning.

3 (guard vs. gate divergence) — fixed. Right that git diff --quiet cannot see a file git has never been told about, while gen:mcp:check stages with --intent-to-add first. Today only the version field moves so the two agree, but a guard mirroring a check should mirror it rather than leave the next reader working out whether the divergence was reasoned. Now:

pnpm gen:mcp
git add --intent-to-add --all bestax-mcp/data
if git diff --quiet -- bestax-mcp/data; then ...

Verified both directions locally: restamped index reports no change; an untracked file under data/ now reports a change where the bare diff did not.

1 (failure surfaces only as a red publish job on main) — accepted, inherent. The step runs after publishing precisely so it cannot cost a release, which puts it on a main push where there is no PR to annotate. The trade is deliberate: a red main run plus an ::error:: naming the fix beats silently reverting to the behaviour this PR removes. Worth confirming someone watches main-branch runs, as you note — that is an operational question rather than a code one.

2 (no concurrency: on the publish job) — real, pre-existing, deliberately not fixed here. Correct that the restamp inherits it rather than introducing it: semantic-release's own push already non-ff's if two merges land together. Adding concurrency: { group: publish-main, cancel-in-progress: false } would serialise releases and make my push more reliable too, but it changes release scheduling, which is a behaviour change to the most consequential job in the repo and belongs in its own PR with the maintainer's explicit sign-off rather than riding along here.

Also confirming the three things the review checked that I had assumed rather than verified: that @semantic-release/git advances local HEAD before this step runs (so pnpm gen:mcp reads the bumped version), that git push HEAD:main is a fast-forward, and that chore(bestax-mcp) clears commitlint without triggering a bestax-mcp release. Good to have those independently traced.

#	Severity	Area	Finding	Location
1	🔵 Advisory	Security	--no-verify only bypasses pre-commit/commit-msg; a future husky prepare-commit-msg/post-commit/post-rewrite hook would run repo code in the one step holding the bypass token, silently defeating the I1 split. Holds today (only commit-msg exists).	.github/workflows/ci.yml:386

Overall: The change is sound and the reasoning is unusually well documented. The mechanism is correct: semantic-release mutates bulma-ui/package.json in the working tree, gen-mcp-index.mjs reads that version (line 542) into the committed catalog.json, and the new final step regenerates + pushes it back to main — closing the exact drift that reddened #518/#520. I verified the generator is deterministic (sorts everything by code point, no timestamp/random, ICU collation already de-flaked), that the guard mirrors gen:mcp:check byte-for-byte, that the fix is complete (only the MCP index carries the version stamp — component-catalog.md does not, so no companion regen is missing), and that the two review rounds already landed the two real issues: token-out-of-code-execution (commit ca91b64) and guard/gate parity (commit 02bda15). The riskiest surface is the post-publish push: on failure the job goes red with packages already out — but that is the deliberate, clearly-signposted fail-loud behaviour, not a defect. Human should focus first on confirming the I1 split is airtight (finding #1) since that is the PR's central security property.

Residual risk:

• The drift recurring — refuted: on a release run the only working-tree delta is the version field, and the step regenerates against that same tree; on a non-release push the identical Node-24 toolchain yields byte-identical output so changed=false and nothing is pushed.
• The token leaking to repo code — largely refuted: git/gpg are system binaries, there is no .gitattributes clean filter, and the sole husky hook (commit-msg) is bypassed. The one remaining seam is finding #1 — --no-verify is hook-name-specific rather than a blanket core.hooksPath=/dev/null, so it does not cover every hook git may fire post-commit. No such hook exists today.
• Push races / non-fast-forward — accepted, pre-existing: a concurrent external push to main fails the push with packages published. This is the documented intentional signal and is inherent to the existing semantic-release push too, not introduced here.

🏄 Righteous fix, dude — main's been quietly leaking stale version stamps onto every fresh branch and this seals the leak clean, keeps the release token far from the code, and even left the comments as a surf journal for the next paddler. No gnarly wipeouts here — good to send it.

Re-review handled — advisory 1 fixed in f58d932.

--no-verify was the wrong shape for this, and you are right about why. It suppresses pre-commit and commit-msg only. A prepare-commit-msg, post-commit or post-rewrite hook would still run repo-owned code inside the one step holding the bypass token — and it would do so silently, the day someone adds an unrelated hook, with nothing connecting that change to this security property.

Switched to git -c core.hooksPath=/dev/null commit. Pointing hooksPath at a non-directory makes git find no hook of any name, which is the property actually wanted here: no repo code runs in this step, rather than these two hooks are skipped.

Verified rather than assumed, with a scratch repo carrying a post-commit hook:

commit form	hook fired
git commit	yes
git commit --no-verify	yes
git -c core.hooksPath=/dev/null commit	no

The middle row is your finding reproduced exactly.

On the residual risks: agreed the post-publish push failing is the deliberate fail-loud signal rather than a defect, and agreed the non-fast-forward race is pre-existing and inherited from semantic-release's own push rather than introduced here. That one is tracked as a possible concurrency: guard on the publish job, which I have deliberately kept out of this PR since it changes release scheduling.
