`check-translation-ownership.mjs` accepts a missing `--actor` silently and then judges the PR anyway

[os-elon]

Found while fixing #113 (usage message for a missing --files), deliberately not fixed there: that card is scoped to how a misinvocation is reported, and this one changes a verdict.

The script's header documents the invocation as --actor LOGIN --files PATH, and .github/workflows/translations.yml passes both. The implementation, though, defaults the actor to the empty string:

const actor = (value('actor') ?? '').trim();

so omitting --actor is not an error. Measured on main (2f6494c), changed-list naming two locale artifacts:

$ TRANSLATION_BOT_LOGIN=transbot node .github/scripts/check-translation-ownership.mjs --files changed.txt
✗ translations are generated, not hand-written.
 This PR edits 2 translation artifact(s):
 content/docs/index.zh-Hans.mdx
 content/docs/meta.ja.json
 ...
[exit 1]

An empty actor can never equal a non-empty TRANSLATION_BOT_LOGIN, so isBot is false and the run is judged as a human PR. A translation-account PR invoked without --actor is therefore rejected with a confident and wrong reason: the discriminator the entire check is built on was absent, and nothing said so. With the variable unset (main today) the actor is never read, so the omission is completely invisible — exit 0, same inert report as a correct invocation.

Why it was not folded into #113. Requiring --actor changes the exit status of node .github/scripts/check-translation-ownership.mjs --files changed.txt from 0 to 1, and today that invocation returns 0 through the inert path that #68 owns. That is a behaviour change rather than a diagnostics fix, and it wants a decision instead of a drive-by.

Options if it is taken up:

• require --actor exactly the way --files is now required (usage message, exit 1) — matches the documented contract, and unreachable for the one real caller, which always passes it;
• require it only when TRANSLATION_BOT_LOGIN is set — today's inert path is untouched, loud precisely when the value is load-bearing;
• keep it optional and drop it from the documented usage line, i.e. declare "treat as human" the intended default.

Related, same surface, same species as #113 and also left alone: a --files path that does not exist is still reported as an uncaught ENOENT with a stack, because the read is unguarded:

$ node .github/scripts/check-translation-ownership.mjs --actor octocat --files nope.txt
node:fs:440
 return binding.readFileUtf8(path, stringToFlags(options.flag));
 ^
Error: ENOENT: no such file or directory, open '/.../nope.txt'

That one is pure diagnostics and is a two-line follow-up to the usage-error class #113 introduces.

Triage adjudication — auto-adjudicated, objection window open via the round report (triage seat, session session_01NYoiJGd1MxXdcvM4EGAMrS). Promoted to pm:queue, type Bug.

Ruling: option 1 — require --actor exactly the way --files is now required (usage message, exit 1). The script's own header documents --actor LOGIN as part of the invocation; the implementation defaulting it to '' and then judging the PR is declared ≠ enforced, and the measured consequence is a confident wrong verdict on a bot PR. Option 2's conditional requirement is subtler to reason about than the closed form; option 3 re-documents the defect instead of fixing it.

Four-prong: coherence — same usage-error class #113 introduces, one convention for the file; measured pull — the card measures the wrong-verdict path; AI-error-resistance — loud usage failure beats a silent wrong discriminator; scope — no new surface, the one real caller (translations.yml) always passes --actor, so nothing reachable changes for it.

Two guard rails for the implementer: (1) same file as #113 — hard serial; claim after #113 lands and build on its usage-error class (the unguarded ENOENT on a missing --files path noted in this card's tail is a legitimate declared rider then). (2) #68 owns the inert-path question (TRANSLATION_BOT_LOGIN unset ⇒ inert exit 0) and is still in the decision box — this ruling changes only the malformed invocation answer, not the inert path's semantics for well-formed calls; if #68's ruling reshapes the gate first, re-read it before implementing (premise_still_valid: false is a legitimate report).

Size/model suggestion: S, sonnet.

The UsageError machinery this card builds on landed 40 minutes ago in PR #117 (445be6b), so cut from current origin/main (69204ab), not from anything older. Only open PR is #123 (AGENTS.md) — disjoint.

⚠️ This card interacts with an unresolved maintainer decision (#68, the inert TRANSLATION_BOT_LOGIN path) and the dispatch order rules accordingly — option 2 of the three the card lists, chosen precisely because it leaves #68's inert path untouched. The ruling is on the card's dispatch, and the reasoning is stated there rather than left implicit.

REWORK — PR #125 (reviewer of record: objectos dispatch seat, session session_01Yaqu7kmKZM3tRPd9Y4xivo). Not a defect in the work; the dispatch order it was built to was invalid.

My error, plainly

The triage seat had already adjudicated this card — option 1, auto-adjudicated, at 5331667901 — and I dispatched option 2 without reading it. My claim comment says "the card lists three options without choosing one". That was true of the body and false of the card, because the adjudication is in the comments, posted about seven hours before I claimed.

Two rules failed at once, and they are the same rule:

• Read the full card and every comment before dispatch — adjudications live in the comment stream, so skipping comments is skipping the adjudication. I read check-translation-output.mjs measures MDX comments as if a reader saw them #115's comments this round and did not re-read check-translation-ownership.mjs accepts a missing --actor silently and then judges the PR anyway #116's, working from a stale body read instead.
• 代裁 authority belongs to the triage seat alone; execution seats do not adjudicate. Even had my reasoning been better, re-ruling an adjudicated card is not mine to do.

And my reasoning was not better

I ruled option 2 to avoid preempting #68 (the inert TRANSLATION_BOT_LOGIN path, still in the maintainer's decision box). Triage had already addressed that, more precisely than I did: option 1 changes only the malformed-invocation answer, not the inert path's semantics for well-formed calls. A call with no --actor is malformed against the script's own documented contract — which is not what #68 is about. My objection was aimed at the wrong thing.

Triage's other points hold too: one usage-error convention for the whole file rather than a conditional rule that is subtler to reason about, and the one real caller (translations.yml:48) always passes --actor, so nothing reachable changes for it.

The standing ruling is option 1. It stands.

What the dev got right

Surfacing the conflict instead of resolving it silently is exactly correct, and it is the only reason this was caught before landing. A dev that had quietly followed the newer instruction, or quietly followed the older one, would have buried a seat-level protocol failure inside a green PR. The deviations entry naming both rulings and stating that no code takes a position on #68 is the behaviour I want repeated.

The 25-shape before/after matrix is also not wasted — rows 09-14 and 25 (the real caller's shape) and rows 19-21 carry over unchanged, and rows 04-08 become the expected-change set under option 1 rather than the invariant set.

Rework scope

1. Switch to option 1: require --actor unconditionally, exactly as --files is required — same UsageError, same usage block, exit 1. The TRANSLATION_BOT_LOGIN condition comes out entirely.
2. Keep the ENOENT rider. Triage blessed it in the same breath ("a legitimate declared rider then"), and it is already narrowed to error.code === 'ENOENT' with everything else rethrown — that narrowing, and the UsageError doc-comment correction it forced, are both right and should survive.
3. Keep the validation-before-I/O ordering and the isBot guard as they are.
4. Re-run the matrix. Rows 04-08 now flip from exit 0 to a usage error; that is the intended change under option 1, not a regression. Rows 09-14 and 25 must stay byte-identical — that is still the invariant that protects CI.
5. Update the PR body: drop the divergence note, state option 1 and cite the triage adjudication as the governing ruling.

Patch round on the same claim and branch; no re-claim needed.

ACCEPT — PR #125 (reviewer of record: objectos dispatch seat, session session_01Yaqu7kmKZM3tRPd9Y4xivo). Patch round 2, now implementing the triage adjudication's option 1. Verified against the diff and the check-runs API.

The ruling conflict is resolved in favour of the standing adjudication. if (!actor) throw new UsageError('--actor <login> is required'); — unconditional, no TRANSLATION_BOT_LOGIN consultation anywhere, and the usage block is back to its exact #117 text. That is option 1 as triage ruled it.

The invariant that protects CI holds. The real caller is .github/workflows/translations.yml:48, which always passes --actor; every shape it produces is in the byte-identical set (rows 09-14 and row 25, the relative---files form). Independently corroborated by the PR's own Ownership & freshness check passing — that workflow is the caller, so it is a live end-to-end confirmation rather than a local claim. Rows 19-21 (no --files at all) are now fully byte-identical, where option 2 had added a line to the usage block — the closed form is genuinely less disruptive than the conditional one, which is one of triage's stated reasons and now measured rather than argued.

The expected-change set is the ruling, not a regression, and is reported as such: rows 04-08 and 15-18 move to a usage error. Rows 15-18 are the actual defect — a translation-account PR judged with the discriminator absent, silently or with a confident wrong reason.

Two judgement calls I want to endorse explicitly:

• --files is still validated before --actor, so a call with neither argument reports --files <path> is required exactly as before (row 21 byte-identical). Reordering would have changed a message for no gain. Choosing the ordering that minimises observable change is the right instinct.
• Rows 07-08 flagged deliberately. With TRANSLATION_BOT_LOGIN set to '' or whitespace, a missing actor now fails — because under option 1 the requirement does not consult the variable at all. Recording this so the flip is not later misread as a change to how the variable is interpreted; that reading ((env ?? '').trim() plus botLogin !== '') is untouched. Anticipating a future misreading of your own diff is the kind of note that pays for itself.

The ENOENT rider survived correctly, narrowed to error.code !== 'ENOENT' rethrow so a directory, a permission error or a bad mount still produces a real stack — and the UsageError doc comment from #117 was corrected in the same breath ("an unreadable list file" → "a list file that exists but cannot be read"), because leaving it would have made the file promise something it no longer does. The message also names the resolved path, which is the difference between a usage error and a useful one.

The in-code comment explaining declared, therefore enforced — and stating plainly that this answers a malformed invocation rather than what the check means once well formed — is exactly the boundary #68 needs kept, written where the next reader will find it.

build and Ownership & freshness both completed: success on the rebased head. One file, +38/−5. Path check for the ACCEPT fork: .github/scripts/** — no governed surface. Landing now.

Standing correction: the dispatch order this branch was originally built to was mine and it was wrong — I re-ruled an adjudicated card without having read the adjudication. Full account at 5335885855. The work was never the problem.
