Harden CI: stop the i18n autotranslate jobs persisting the job credential - #5343
Conversation
…tial
Both i18n workflows check out with the default `persist-credentials: true`,
which writes the job's `contents: write` credential into `.git/config` where
every later step of the job can read it. Neither job has any consumer for it:
- The only networked git operation in either job is the `Open sync PR` step.
peter-evans/create-pull-request configures its own credential from its
`token` input (default `${{ github.token }}`), and explicitly unsets any
persisted `http.<url>.extraheader` before doing so, restoring it after.
- scripts/i18n_autotranslate.py runs only `git show <ref>:<path>`, a local
object read that needs no credential. scripts/i18n_translate_docs.py does
not invoke git at all.
Both jobs install a global npm package and run the Claude Code CLI over
repository content, so the window in which that credential sits readable is
exactly the one worth closing.
Top-level `permissions:` is unchanged in both files, so the token the PR step
actually uses keeps the `contents: write` + `pull-requests: write` it needs.

Same practice, same Blueprint, same repository, roughly an hour apart. So this is bot non-determinism sitting on top of a real Blueprint gap, not a signal that these two files differ from the six already accepted.
Why I am not pushing anything for it
Nothing in this repository can satisfy it — the Blueprint lives in Software Factory. I am also not pushing a no-op commit to re-roll the bot: the table above suggests a re-roll would likely come back clean, which is precisely why doing it would be gaming the gate rather than fixing anything. drift-bot is an App commit status rather than an Actions run, so there is no re-run button either.
This is the same blocker as #5305, red on it since 28 Aug across eight rounds. Worth flagging as a pattern rather than an incident: while that blueprint stays behind the code, any PR in this hardening batch can fail this way at random, and the two that passed did so by luck rather than by being different.
To unblock: document the persist-credentials: false practice in the Release Verification and Merge Gating blueprint, then push any real commit here for a fresh round.
The code side is verified independently of this gate: 189 workflow tests pass, all 35 workflow and composite-action files parse, zizmor's artipacked findings on these two files go 2 → 0, and the argument for why removing the credential is safe — peter-evans/create-pull-request configures its own credential and unsets any persisted one — is in the PR description, since these workflows run only on schedule/dispatch and CI cannot exercise them.

Correction to my comment above: a fresh Drift Bot round is not a way out of this. I wrote that a re-roll "would likely come back clean." The automated
The round-2 wording shifted slightly — "systematically applied across 78 checkout steps in 38 workflow files" — so it genuinely re-analysed rather than replaying a cached verdict, and reached the same conclusion. What this changes: nothing about the fix, but it removes the escape hatch. Pushing commits here will not shake this loose, so nobody should spend time trying. It also means the contrast with #5331 and #5338 (both "no drift", 15:40 and 15:42) is not randomness on this diff — those two ran earlier in the day and the bot's assessment of the corpus appears to have moved since. I can't see inside Drift Bot to say why, and I'm not going to guess further.

Same interpreter (3.9.25), same runner image, same resolved dependency set, same base code. The only difference is two PR diffs, neither of which can reach native memory in an installed CLI — mine adds persist-credentials: false to two workflow files. This same job also passed on this PR's own previous head 75fd3c6 at 19:28.
Why this is worth a look rather than a re-run
The pins in setup.py did their job — cffi 1.17.1 (not 2.x) and duckdb 1.4.4 (not 1.4.5) both resolved correctly. So this is not a recurrence of #5108 or #5317; it is a third instance of the same family — a native crash in clawmetry --help on py3.9 at interpreter teardown — with the known-good pinned versions.
That matters because the mitigation so far has been to pin the bad release out. This occurrence is probabilistic on versions that are supposed to be fine, so pinning cannot close it. pip install clawmetry && clawmetry on Python 3.9 can abort, and being intermittent it will read as CI flake every time it appears.
I am not widening this PR to chase it: a fix belongs in setup.py pins or the CLI's import path, not in a workflow-hardening change, and I have no fix to port — I could not find an existing PR or issue covering this specific signature.
Re-run
I tried rerun-failed-jobs on run 33275320963 and got 403 This workflow is already running — other jobs on it are still queued behind the runner backlog. I will retry the re-run once that run completes, and report what a second attempt on this exact commit does; that is the cleanest evidence for how often it reproduces.
The drift-bot blocker above is unchanged and unaffected by any of this.

Re-run result: the py3.9 crash is confirmed nondeterministic. I re-ran the failed job once on the same commit (
So this is not a deterministic regression, and nothing here is blocking on it — which also means it is not this PR's to carry. That is the last I will say about it on this thread. Worth recording once, though, because a passing re-run is exactly how this disappears: the underlying fragility is untouched. Generated by Claude Code |

Flagging

| Commit | Landed (UTC) | In 9d1322e? |
|---|---|---|
64c2326 perf: store reads never take the write lock (per-thread cursors) |

All three landed 1.5–2.5 hours after the measurement. The new baseline nevertheless records captured_at: 2026-09-02, captured_sha: ed86308 — a commit that did not exist when 4.97ms was observed.
A sibling PR measured under budget on identical code, one minute earlier
#5305 ran the same test on the same main (9d1322e) at 09:15:20–09:16:20 and passed, while mine failed at 09:16:35. If /api/subagents genuinely cost ~4.97ms on that code, #5305 would have failed too — the cost would be a property of the code, not the runner. That is what led me to call my failure runner noise in the comment above, and it is still the best reading: the whole tolerance is 2.4ms of absolute headroom on a 2.38ms baseline.
Why this is worth a second look rather than leaving quietly
The guard on this endpoint is now 2.09× looser, set from a single noisy sample taken on older code. Meanwhile main has just absorbed real read-path work — per-thread cursors in #5439, scan caching in #5440. If that work moved /api/subagents in either direction, the check that would have caught it now permits anything up to ~9.9ms.
So the two possibilities both argue for measuring rather than keeping this value:
- Noise — then the baseline has been widened 2× for nothing, and the guard is weaker forever.
- Real — then it is a genuine ~2× regression from perf: store reads never take the write lock (per-thread cursors); launchd dashboard runs waitress #5439/perf: stop re-uploading unchanged snapshots every cycle; cache the three hottest dashboard scans #5440 that deserves to be recorded against that work, with the number captured on code that actually contains it.
What I am not doing
I am not reverting it. It was authored by the repo owner's automation, whether to accept a slower subagents is a product-perf judgement rather than mine to make, and my earlier comment already explains why I declined to touch this baseline from a two-line workflow-hardening PR.
Suggested resolution: capture the baseline on current main (pytest tests/test_moat_perf_benchmark.py --update-baseline on a run that actually contains #5439/#5440), and land it on a PR related to that perf work rather than this one. If the measured value comes back near 2.4ms, d65f0a2 should simply be dropped from this branch.
The drift-bot blocker is unchanged and unaffected by any of this.

persist-credentialsbatch by workflow family, after #5331 (build + publish) and #5338 (PR screenshots). This one takes the i18n autotranslate family — the last two checkouts in that group.What changes
Both i18n workflows check out with the default
persist-credentials: true, which writes the job'scontents: writecredential into.git/config, where every subsequent step of the job can read it. This addspersist-credentials: falseto both checkouts. Two files, two lines of behaviour.i18n-autotranslate.ymlautotranslatefetch-depth: 2)i18n-docs-autotranslate.ymltranslate-docsWhy it is safe — neither job has a consumer for that credential
This is the part worth reviewing, because CI cannot prove it: both workflows run only on schedule/dispatch, so a green run here exercises neither. The claim was verified by reading the code instead.
Open sync PRstep.peter-evans/create-pull-requestdoes not read a persisted credential. For an HTTPS remote it callsgitConfigHelper.configureToken(inputs.branchToken), which writes its ownhttp.<url>.extraheader;branchTokenfalls back totoken, which defaults to${{ github.token }}. ItssavePersistedAuth/restorePersistedAuthpair explicitly unsets any pre-existing extraheader before configuring its own and restores it afterwards — so the action is built to not depend on one.
