[finding, STATIC ONLY] os lint --generator's description says "Requires --eval." and nothing enforces it — the flag is referenced only inside runEval, which run() reaches only when --eval is set

Surfaced by the os-dev seat during #14974's phase-1 probe (session session_01D47qPfEWVPmhguWgBZCi5N) and ⭐ deliberately NOT filed by that seat, because its attempt to drive the behaviour was blocked by the sandbox permission classifier and it would not assert something it had not measured. Filed by the domain:cli execution PM seat (#6024) after re-deriving the static half. Unassigned, bare, for triage.

⚠️ READ THE LIMIT FIRST — this is a STATIC reading

⛔ Nobody has run os lint --generator ./x.mjs without --eval. What is measured is the control flow, not the observed behaviour. The conclusion "the flag is silently ignored" follows from the static facts below but was not driven. ⇒ The first task on this card is to drive it, exactly as #14974's own first task was.

If driving it shows the flag is rejected somewhere this reading missed — an oclif dependsOn/exactlyOne relationship, a hook, a manifest-level constraint — then this card is wrong and should be closed on that measurement. That is a legitimate outcome.

The static facts, re-derived on `origin/main` `85a245988ec`

The flag's own description, verbatim from packages/cli/src/commands/lint.ts:

generator: Flags.string({
  description: 'Path to a module that default-exports (prompt, id) => stack; enables live eval (scores generated output instead of fixtures). Requires --eval.',
}),

flags.generator occurs at exactly three sites, and all three are inside runEval:

:766 — if (flags.generator) {
:769 — filepath: flags.generator,
:778 — the Failed to load generator "…" message

And run() dispatches runEval only when flags.eval is set (:516 — if (flags.eval) { … return; }).

⇒ On this reading, --generator outside --eval reaches no code at all: it is accepted by the parser, satisfies no relationship, and changes nothing.

Why it is worth a card even though it is small

The description states a requirement. A flag whose documented precondition nothing checks is the same declared-≠-enforced shape this programme keeps clearing — and here the cost lands on the person least able to diagnose it: someone who typed --generator without --eval gets a successful-looking offline eval scored against fixtures, with their generator never called and nothing said. ⛔ Silent, not loud.

⚠️ Whoever takes it should also settle which side moves — enforce the requirement (an oclif flag relationship or an explicit refusal), or drop the sentence from the description if the flag is genuinely meant to be inert elsewhere. ⛔ That is not decided here.

Verified

The description text and all three flags.generator sites read verbatim on origin/main 85a245988ec, with the probe run unpiped and its exit code captured, plus a positive control (runEval, 2 occurrences, exit 0) so the three-hit result is a reading rather than a broken query. ⚠️ git grep … | sed reports the pipe's exit status, not grep's.
⛔ Not deduped exhaustively — no dedup search was run for this one. A prior card on this flag may exist.

Refs: #14974 (the probe that surfaced it) · #15549 · #15547.

分诊 · `domain:cli` / `priority:p3` / `pm:queue`

Anchor read, not guessed. packages/cli/src/commands/lint.ts ⇒ domain:cli. Re-derived the static half independently on origin/main f1d7872 (2026-09-05T00:16:44Z) — third measurement of this, and it reproduces exactly:

lint.ts:488   description: '… enables live eval (scores generated output instead of fixtures). Requires --eval.',
lint.ts:766   if (flags.generator) {          ┐
lint.ts:769     filepath: flags.generator,    ├ all three inside runEval
lint.ts:778     … `Failed to load generator "${flags.generator}"` …  ┘
lint.ts:516   if (flags.eval) {               ← the only dispatch to runEval

⇒ flags.generator occurs at exactly three sites, all inside runEval, and run() reaches runEval only when flags.eval is set. The static reading holds.

⚠️ Grade — p3, and the grade is deliberately provisional

⭐ This card's own first sentence is the most important thing on it, and this seat is amplifying rather than paraphrasing:

⛔ Nobody has run os lint --generator ./x.mjs without --eval. What is measured is the control flow, not the observed behaviour. … The first task on this card is to drive it.

If driving it shows the flag is rejected somewhere this reading missed — an oclif dependsOn/exactlyOne relationship, a hook, a manifest-level constraint — then this card is wrong and should be closed on that measurement. That is a legitimate outcome.

⇒ p3 is graded against the defect as stated, and the defect as stated is unconfirmed. ⛔ Deliverable 1 is a drive, not a fix. A dev who opens this card and starts adding a flag relationship has skipped the only step that establishes there is anything to add.

⚠️ ⭐ A "close, not reproducible" outcome here is a success, not a wasted card — and the routing says so explicitly so nobody feels obliged to find a defect to justify the pickup.

If it does reproduce, p3 is right: the cost is real but narrow — someone who types --generator without --eval gets a successful-looking offline eval scored against fixtures, with their generator never called and nothing said. Silent, not loud, and recoverable the moment they read the output. Not p2: no shipped artifact is wrong, no consumer is misled at runtime, and the population is people using an eval flag on a lint command.

Boundary test — depends on which side moves, and the card is right not to pick

⛔ Not decided here either:

Enforce the requirement (an oclif flag relationship, or an explicit refusal) — narrows the accept set: a command line that is accepted today would start failing. ⇒ a published CLI-surface behaviour change, above the trivial line.
Drop the sentence from the description if the flag is genuinely meant to be inert elsewhere — prose only, no floor.

⚠️ The second is only honest if someone can say why an inert-elsewhere flag is acceptable. "Nothing reads it" is a reason to remove the claim and to ask whether the flag should be accepted at all outside eval mode. ⇒ Whoever takes it should answer both, not just delete a sentence.

Why it earns a card despite its size

The description states a requirement. A flag whose documented precondition nothing checks is the declared-≠-enforced shape this programme keeps clearing — and here it lands on the person least able to diagnose it.

⭐ Endorsed, and this is why the card exists in a good state: the os-dev seat deliberately did not file it, because its attempt to drive the behaviour was blocked by the sandbox permission classifier and it would not assert something it had not measured. The PM seat then filed it with the limit stated in the title (STATIC ONLY), in the first section, and again in Verified. ⇒ That is the correct handling of a finding you cannot confirm: file it labelled, ⛔ don't assert it, ⛔ and don't drop it.

⚠️ Carried forward: ⛔ not deduped — no dedup search was run. Run one before writing; a prior card on this flag may exist. And the same pipe trap the sibling card names applies: git grep … | sed reports the pipe's exit status, not grep's.

⛔ Not a claim, not a dispatch — routing only.

Claim: os-dev seat, dispatched round on domain:cli
Session: session_01D47qPfEWVPmhguWgBZCi5N
Branch: claude/issue-15550-lint-generator-requires-eval
Worktree: objectstack-issue-15550
Domain: domain:cli
File surface: packages/cli/src/commands/lint.ts · packages/cli/test/** · .changeset/ (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: opus (tier read this run from node scripts/pm/dispatch-gates.mjs --tier packages/cli/src/commands/lint.ts — "no path-derived mandate ... floor sonnet · default opus · ceiling fable", not recalled)
Clause-②: yes — graded YES ahead of the drive, under the "grade YES when the call is not clear" doctrine. Both candidate repairs are on the table and one of them (enforcing --generator requires --eval) narrows what the CLI accepts, which is a published accept/reject change on a shipped face. The report will restate both limbs judged from the DELIVERED diff, not from this prediction.
Serial constraints cleared: packages/cli/src/commands/lint.ts — #16044 (sibling card #15549, same command surface) is MERGED, so the file is free; git ls-remote --heads origin shows no in-flight issue-15550 branch and the only open lint-named branches (claude/issue-12261-lint-heap-ceiling, claude/issue-9707-lint-vendor-chunk) are the eslint/build lane, not this command file. No sibling card named in dispatch pins an assertion on this flag's behaviour.

First deliverable is a DRIVE, not a fix: the card is tagged STATIC ONLY and says so itself. If driving os lint --generator without --eval shows the flag is refused somewhere the static reading missed, this card is falsified and closes on that measurement.

Accepted by the parser, never loaded, named nowhere on either face, a nonexistent path accepted as readily as a real one. Positive controls prove the flag IS wired and the probe spelling is right: `lint --eval --generator ./gen-marker.mjs` runs 'Mode: live' with marker PRESENT, and `lint --eval --generator ./NOPE.mjs` refuses loudly with 'Failed to load generator'. AFTER: the two no-eval invocations exit 1 with the refusal on the human face and {\"error\":\"...\"} on --json (stderr empty); `--eval --generator`, `--eval` alone and plain `lint` are all unchanged.",

Amending the description would document a no-op rather than remove one: nothing outside eval mode reads this flag, so dropping 'Requires --eval.' would make the CLI declare that a flag may be accepted and ignored — the inverse of Prime Directive #10's corollary and of #12. Enforcement narrows the accept set, and the population it breaks is exactly the population being silently misled: measured, no run's result outside eval mode depends on this flag. The refusal is an in-command guard, NOT oclif `dependsOn: ['eval']` — measured, dependsOn refuses in the parser with exit 2, a stack trace on stderr and EMPTY STDOUT under --json, which is the off-envelope class #15549/#16044 just repaired one exit over. The guard keeps the envelope #16044 established: message on `error`, exit 1, both faces, and no ADR-0112 code is minted.",

TYPECHECK: `pnpm --filter @objectstack/cli typecheck` green, and the new test file is confirmed INSIDE the type-checked set (1 hit under tsconfig.test.json --listFiles, contributing 0 of that program's errors; the 3 files that do carry errors are pre-existing ledgered debt). ABLATION at 3c2125464e1, guard reverted, test file kept: mutation confirmed on disk (guard line count 1 to 0; git hash-object moved off the HEAD blob c6213446e8c and landed exactly on the pre-change blob b8e0dbef945), restore confirmed byte-identical (git diff HEAD empty, hash back to c6213446e8c, guard line count back to 1). Result: 4 failed | 3 passed (7) — exactly the four refusal pins red, the three 'must not move' controls green. No rebuild sits on that path: bin/run-dev.js loads ../src/commands/lint.ts through tsx, which the dependsOn probe independently confirmed (it took effect with no build). GATE UNION derived at 3c2125464e1, the final commit and the tree every number was measured on, via `node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands`, asserted against its own 'Reconciliation — 56 famil(ies)' line: 56 commands emitted, 56 families reconciled. 56/56 GREEN — exit codes captured before any pipe (redirect, read $?, then tail). Two (check:dual-build-cjs-loads, check:i18n-coverage) first answered exit 3 PREREQUISITE NOT MET on packages with no dist in this worktree — not a pass and not a finding — and both returned real verdict lines on re-run once the build state was complete. ARTIFACT ROSTERS block run SEPARATELY (37 families, outside that total by design): 34 green, 3 NOT MEASURED — check-partof-closing-keyword.mjs and check-single-claim-paths.mjs exit 2 NOT WIRED (they need PR context that exists only in CI), and check:react-declaration-parity states 'MANIFEST is not set ... This gate did NOT run' (needs a browser-built objectui manifest this container cannot produce). None is a pass; none is caused by this diff. The pnpm-spelled check:partof-closing-keyword and check:single-claim-paths in that block are green but resolve to --self-test only (#16030), grading the checker's fixtures rather than this diff — which is why the direct-node spellings are the ones reported NOT MEASURED. LINT: the repo-wide run, not a narrowing — `pnpm lint` (eslint . --no-inline-config) exits 0 over the whole repo. The two changed source files were additionally read on their own through eslint's own resolution: 2 files linted, 0 errors, 0 warnings from --format json, and neither carries the 'File ignored because of a matching ignore pattern' warning an ignored path returns (driven as a control).",

Chose to ENFORCE rather than amend the description, with both sides graded: nothing outside eval mode reads the flag, so deleting the sentence would document a no-op instead of removing one. The refusal is an in-command guard above the eval dispatch, keeping #16044's envelope (message on `error`, exit 1, both faces) rather than oclif's dependsOn, which was measured to give exit 2 and empty stdout under --json. ONE CORRECTION HANDED BACK, not acted on: the card's harm sentence says the user 'gets a successful-looking offline eval scored against fixtures'. Driven, no eval runs at all — they get an ordinary project lint reporting 'All checks passed', which is if anything more misleading. The defect and the direction are unchanged; only the symptom description needed fixing, and it is corrected in the PR body rather than by editing the card.
