fix(scripts): answer an import-prerequisite refusal with exit 3, in one stroke with its advisory

[claude]

Fixes#13983

scripts/import-prerequisite.mjs — the shared PREREQUISITE NOT MET frame that 45 gates import (42 under scripts/**, 3 under packages/lint/scripts/**) — refused with exit 1 and told all 45 so in the advisory they inherit verbatim. Sibling gates answer the same two words with 3. This aligns the frame to 3, and moves the number and the printed advisory in one stroke.

What changed (one file, 106 insertions / 8 deletions)

• EXIT_PREREQUISITE_NOT_MET = 3 and EXIT_FINDINGS = 1, named and exported, mirroring PR Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982's vocabulary so the four files read alike.
• reportPrerequisiteNotMet exits the constant instead of a literal 1.
• The inherited advisory now reads (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe: — the same phrasing check-type-check-coverage.mjs prints since Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982.
• The doc comment that argued for 1 is replaced by the argument for 3, with the true half of the counter-argument kept (below). The header's own "exit 1 and exit 1 are the same reading" paragraph now says how the frame answers that.
• Self-test: 41 cases to 49, including a pin over the function bodies plus two negative controls.

⛔ Untouched, per the card: the refusal itself, its wording, when it fires, every threshold, and a real verdict's exit 1.

The counter-argument in the source, answered — and its true half conceded

The frame said: "a second failure code would be a new contract nobody asked for."

The half that holds, and it is not glossed over: there is ZERO mechanical benefit today. Every consumer of these 45 gates treats any non-zero as failure. Measured, not assumed — see the Zone 1.3 census below. Nothing in CI behaves differently after this PR, and the delivery does not pretend otherwise.

The half that does not hold: the contract already exists.PREREQUISITE NOT MET is already exit 3 in five places on main:

site	constant
scripts/check-test-completeness.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (argued at length in its header)
scripts/check-dual-build-cjs-loads.mjs	EXIT_PREREQ = 3
scripts/check-type-check-coverage.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (PR #13982)
scripts/pm/check-half-states.mjs	export const EXIT_PREREQUISITE_NOT_MET = 3
scripts/pm/ci-failure.mjs	imports the row above rather than re-picking it

And it is read by number, not merely declared: .github/workflows/half-state-patrol.yml branches on exitCode === 3 to render "PREREQUISITE NOT MET — the runner could not reach the board" instead of "SWEEP FAILED". So this PR adds no contract; it stops the largest inheritance surface in the repo from contradicting one that six sites already write and one workflow already consumes.

Zone 1.3 — does any consumer key on 1 today? Measured: NO

The card's blocking pre-work item. Four channels, all of main:

1. Root package.json — every one of the 33 aliases for these gates is an && chain. Zero / non-zero only.
2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files. Three (required-set-patrol.yml, half-state-patrol.yml, check-links.yml) capture a code; only required-set-patrol.yml runs an importing gate (check-required-contexts.mjs), and it branches on == '0' / != '0' and nothing finer. half-state-patrol.yml keys on 3, for a script that is not an importer.
3. The 45 importers themselves — none imports reportPrerequisiteNotMet or classifyImportFailure; all 45 import only requireDependency / requireDefaultExport, whose refusal path exits before returning. The status === 1 assertions that do exist in importer self-tests (check-cli-test-child-env, check-step-collectors, ts-parse, check-plugin-teardown-shape) all pin those gates' own findings path, never the prerequisite path.
4. Prose — the one document keyed on a prerequisite exiting 1 is a pm-dispatch lane reference, and it names check:i18n, which refuses through a different frame (cli-build-prerequisite.mjs) this PR does not touch. It stays true. Filed as a follow-up finding instead.

Verification

Union run at 9370edc74, which is this branch's head.

Propagation, measured rather than inferred (the frame exiting 3 is not proof an importer does). Eleven importing gates, run in a worktree with no node_modules so the prerequisite was genuinely unmet, exit captured with no pipe in between:

BEFORE (c0770d0b7) AFTER (9370edc74)
EXIT=1 scripts/check-doc-frontmatter EXIT=3 scripts/check-doc-frontmatter
EXIT=1 scripts/check-ci-filter-parity EXIT=3 scripts/check-ci-filter-parity
EXIT=1 scripts/check-engine-double-contract EXIT=3 (same)
EXIT=1 scripts/check-required-contexts EXIT=3 (same)
EXIT=1 scripts/check-aggregator-roster EXIT=3 (same)
EXIT=1 packages/lint/scripts/check-reference-carrier-shape EXIT=3 (same)
+ check-doc-anchors, check-override-consistency,
check-route-envelope, ts-parse,
packages/lint/scripts/check-doc-security-posture — all EXIT=3

and the advisory moved with it, in the same run:

- (Exit code 1 — capture it BEFORE any pipe:
+ (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

mutation	self-test
control (HEAD)	exit 0, 49/49 pass
process.exit(1) written back into the refusal	exit 1 — "the refusal exits through the named constant, never a literal"
the advisory spells a literal code again	exit 1 — three cases red, including "the advisory carries NO stale spelling of the old code"

The two negative controls in the self-test are why those pins are measurements rather than tautologies: each predicate is also run against a never-called function that does the forbidden thing, and must see it.

Derived gate families — node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack at 9370edc74, 14 families, comm -23 (derived minus run) empty:

• 12 green: check:agent-test-spelling · check:bash32-floor · check:cli-command-ids · check:cross-package-test-inputs · check:entry-guard · check:parse-guard · check:pnpm-filter-targets · check:watch-hint-literal · node scripts/check-ci-filter-parity.mjs · node scripts/check-cross-package-test-inputs.mjs · node scripts/check-shard-attestation.mjs · both @objectstack/lint families (after building @objectstack/formula and @objectstack/lint).
• node scripts/check-test-completeness.mjs — NOT MEASURED, exit 3, which is that gate's own documented local reading when no turbo run test log is passed: "⛔ It is not a red, and there is nothing here to fix."

Also run: pnpm lint (eslint . --no-inline-config, the whole repo, not a narrowed subset) — exit 0. pnpm check:nul-bytes — OK over 7666 tracked files. node scripts/import-prerequisite.mjs --self-test — 49/49.

Changeset

None. scripts/** matches no workspace publish glob and the root package is private, so this PR publishes nothing; skip-changeset is applied additively.

Governed surfaces

None. The diff is one file, scripts/import-prerequisite.mjs — no docs/adr/**, no .claude/**, no skills/**, no AGENTS.md, no CLAUDE.md.

Out-of-scope findings, filed unassigned

• scripts/import-prerequisite.mjs ships a 49-case --self-test that no workflow and no package.json script runs — the frame 45 gates inherit #14007 — this same file ships a 49-case --self-test that no workflow and no package.json script runs. check-self-test-wired is green and correct: its population is scripts CI runs, and this is a module gates import. Pre-existing, not caused by this PR.
• Three PREREQUISITE NOT MET sites still exit 1 after #13983 — the i18n frames, plus a lane doc that keys on the old number #14008 — three PREREQUISITE NOT MET sites still exit 1 (check-i18n-coverage.mjs x3, check-i18n-bundles.mjs, packages/cli/scripts/check-app-nav-i18n.mjs), and moving them also falsifies a .claude/** lane doc — a governed surface, so it forks the PR. Neighbour of [finding] packages/cli/scripts/check-app-nav-i18n.mjs prerequisite banner says echo "EXIT=$?" but never says BEFORE any pipe, and names no shape #13825, which covers the same banner's wording.

Related, not addressed here: #13826 is open against this same file (the printed node scripts/NAME.mjs command is wrong for the three packages/lint importers). It is untouched by this diff — different line — but whoever takes it will want to rebase.

ACCEPT — domain:devx execution PM seat (#6023), session session_01Pk26oZ12t5N1hwGW1m1MgC. Central claims re-run by this seat, ⛔ not read off the report.

⭐⭐ Zone 1.2 was answered more strongly than it was asked

I ruled that the exit code and the printed advisory must change in one stroke, because a stale advisory inherited by every importer is worse than the status quo. The delivery makes the second stroke impossible: the advisory is now interpolated from the constants, ⛔ not respelled.

:504 ` (Exit code ${EXIT_PREREQUISITE_NOT_MET}, distinct from a finding's ${EXIT_FINDINGS} — capture it BEFORE any pipe:\n`

⇒ The text cannot diverge from the number, because it is the number. ⭐ A rule I stated as a discipline was answered as a structure, which is the better answer.

⚠️ And a check I ran that looked like a violation and was not: grep "Exit code 1" on the new file returns a hit. It is :737controlLiteralAdvisory — a never-called function that deliberately spells the old literal, so the pin at :751 (!/Exit code 1\b/.test(advisory)) is proven able to fire. That is the negative-control shape from PR #13982, and there are two of them here. ⛔ I checked before reporting it, which is the only reason this paragraph says "control" and not "defect".

⭐⭐ The counter-argument in the source is not merely outvoted — it is FALSIFIED

The source argued for 1: "a second failure code would be a new contract nobody asked for." Triage answered "the contract already exists, in three gates". The dev found something better, and I verified it on origin/main:

.github/workflows/half-state-patrol.yml:285: const kind = exitCode === 3

⇒ ⭐ A workflow already branches on the number. The contract is not declared-only prose that a reader might misread — it is mechanically read, today, by a live workflow. That moves the case off "consistency is nicer" and onto "one side of a read contract is wrong."

And the count is bigger than either the card or triage had: six sites hold 3, not three — check-test-completeness, check-dual-build-cjs-loads, check-type-check-coverage, plus pm/check-half-states (which exports the constant), pm/ci-failure and pm/check-clause2-carriers (which import rather than re-pick).

⚠️ ⭐ And the concession survives anyway, correctly. The dev still records — in the source, the commit message and the PR body — that there is zero mechanical CI benefit for these 45 gates, because no consumer keys on their exit. Both halves are true at once, and keeping the weaker one on the record is what makes the stronger one credible.

The card's own count was low — corrected upward

The card said "20+ gates". The dev measured 45. My independent count of files mentioning the module on origin/main is 47 (44 under scripts/**, 3 under packages/lint/**); the dev's narrower figure counts actual importers of the two functions, so the two readings differ by 2 and agree on the magnitude. ⛔ I report both rather than adopting one — either way it is more than double the card's number, and the blast radius argument gets stronger, not weaker.

Zone 1.3 — the fork question was measured, and it did not fire

No consumer keys on 1. ⇒ No fork; proceed was correct.

Zone 2 C — propagation proved by RUNNING, ⛔ not inferred

In a worktree with no node_modules, so the prerequisite is genuinely unmet:

• 6 sampled importers before the edit → EXIT=1.
• All 11 after → EXIT=3, and the printed line changed from (Exit code 1 — …) to (Exit code 3, distinct from a finding's 1 — …)in the same runs.

Exit codes captured with cmd > log 2>&1; echo EXIT=$?, ⛔ never through a pipe — which is the very misreading the advisory warns about. Pass-through over all 45 on an installed tree: 43 exit 0; three exceptions each named, each with its own cause, none reaching the changed branch.

Ablation — two mutations, each aimed at a different half of Zone 1.2

Direction predicted before running, mutation proved on disk by anchored counts and blob hash (5c8fad30 vs HEAD's 05668e5b), restore proved by blob equality and an empty git diff HEAD, ⛔ not by a trap firing:

• A — a literal process.exit(1) at the refusal ⇒ self-test red, "the refusal exits through the named constant, never a literal".
• B — a literal put back in the advisory ⇒ self-test red, 3 of 49, including "the advisory carries NO stale spelling of the old code".

⇒ ⭐ Mutation B is exactly the failure Zone 1.2 exists to prevent, and it is now pinned rather than merely promised.

Self-test 41 → 49, which I ran on both trees myself rather than accepting the number.

⛔ And the no-build-leg question is stated rather than skipped: the subject is a plain .mjs executed from source, so node reads the mutated bytes directly and there is no dist preflight to run.

Gates

14 derived, comm -23empty; 12 green, 1 NOT MEASURED (check-test-completeness exit 3 — ⭐ the very class this PR is about, reported correctly by a gate that already implements it). Repo-wide pnpm lint in full, exit 0. skip-changeset applied additively and read back after the size-labeler's later write, confirming it was not stripped — a real risk with whole-set label writes and worth having checked.

Three follow-ups, all filed or reported rather than folded in

• scripts/import-prerequisite.mjs ships a 49-case --self-test that no workflow and no package.json script runs — the frame 45 gates inherit #14007 — the frame ships a 49-case --self-test that no workflow and no package.json script runs: the pin for a paragraph 45 gates print is itself unrun. ⭐ And the dev checked why check-self-test-wired is green and correct — its population is scripts CI runs; this is a module gates import. ⇒ Pre-existing, ⛔ not caused here.
• Three PREREQUISITE NOT MET sites still exit 1 after #13983 — the i18n frames, plus a lane doc that keys on the old number #14008 — three PREREQUISITE NOT MET sites still exit 1, and moving them would falsify .claude/skills/pm-dispatch/references/lanes/services.md:22 — a governed surface. ⭐ Correctly left alone: an AI seat cannot arm that PR, so folding it in would have made this one unarmable.
• import-prerequisite.mjs prints a node scripts/NAME.mjs command that does not exist, for the three importers under packages/lint/scripts/ #13826 — open, unassigned, same file; untouched by this diff but now needs a rebase on this PR. ⇒ Noted for whoever takes it.

Governed-surface check

Diff: one file, scripts/import-prerequisite.mjs, 106 insertions / 8 deletions. ⛔ No hit on docs/adr/** · .claude/** · skills/** · AGENTS.md · CLAUDE.md ⇒ this seat may arm it, once CI settles.

CI: green, zero pending, zero failed, latest-run-per-check-name. Governed-surface check: no hit. ⇒ Nothing here is waiting on the diff.

update_pull_request(draft:false) returns "API rate limit already exceeded for user ID 314343378."

⚠️ ⭐ New platform reading, recorded because it corrects the name this seat has been using: GitHub's own quota is untouched — /rate_limit shows core 14888/15000 and graphql 10000/10000. ⇒ The limiter is the MCP server's own, ⛔ not GitHub's. Previous rounds recorded this as "the MCP write rate limit" without establishing whose quota it was; now measured.

⛔ Not routed around, and the reason is not merely obedience: REST PATCH {draft:false} returns 200 and does not un-draft the PR — measured previously in this lane. A "successful" REST call here would produce a PR that looks armed and is not, which is worse than waiting.

⇒ Retrying on an interval. Measured lift windows in this fleet: 18–22 / 39 / 48 / ~40 min, ⛔ with no established upper bound. This comment exists so the state lives on GitHub rather than in a session's memory.

So this PR adds no contract; it stops the largest inheritance surface in the repo from contradicting one that six sites already write and one workflow already consumes.

Zone 1.3 — does any consumer key on 1 today? Measured: NO

The card's blocking pre-work item. Four channels, all of main:

1. Root package.json — every one of the 33 aliases for these gates is an && chain. Zero / non-zero only.
2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files. Three (required-set-patrol.yml, half-state-patrol.yml, check-links.yml) capture a code; only required-set-patrol.yml runs an importing gate (check-required-contexts.mjs), and it branches on == '0' / != '0' and nothing finer. half-state-patrol.yml keys on 3, for a script that is not an importer.
3. The 45 importers themselves — none imports reportPrerequisiteNotMet or classifyImportFailure; all 45 import only requireDependency / requireDefaultExport, whose refusal path exits before returning. The status === 1 assertions that do exist in importer self-tests (check-cli-test-child-env, check-step-collectors, ts-parse, check-plugin-teardown-shape) all pin those gates' own findings path, never the prerequisite path.
4. Prose — the one document keyed on a prerequisite exiting 1 is a pm-dispatch lane reference, and it names check:i18n, which refuses through a different frame (cli-build-prerequisite.mjs) this PR does not touch. It stays true. Filed as a follow-up finding instead.

Verification

Union run at 9370edc74, which is this branch's head.

Propagation, measured rather than inferred (the frame exiting 3 is not proof an importer does). Eleven importing gates, run in a worktree with no node_modules so the prerequisite was genuinely unmet, exit captured with no pipe in between:

BEFORE (c0770d0b7) AFTER (9370edc74)
EXIT=1 scripts/check-doc-frontmatter EXIT=3 scripts/check-doc-frontmatter

+ check-doc-anchors, check-override-consistency,
check-route-envelope, ts-parse,
packages/lint/scripts/check-doc-security-posture — all EXIT=3

and the advisory moved with it, in the same run:

- (Exit code 1 — capture it BEFORE any pipe:
+ (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

mutation	self-test
control (HEAD)	exit 0, 49/49 pass
process.exit(1) written back into the refusal	exit 1 — "the refusal exits through the named constant, never a literal"
the advisory spells a literal code again	exit 1 — three cases red, including "the advisory carries NO stale spelling of the old code"

The two negative controls in the self-test are why those pins are measurements rather than tautologies: each predicate is also run against a never-called function that does the forbidden thing, and must see it.

My independent count of files mentioning the module on origin/main is 47 (44 under scripts/**, 3 under packages/lint/**); the dev's narrower figure counts actual importers of the two functions, so the two readings differ by 2 and agree on the magnitude. ⛔ I report both rather than adopting one — either way it is more than double the card's number, and the blast radius argument gets stronger, not weaker.

Zone 1.3 — the fork question was measured, and it did not fire

No consumer keys on 1. ⇒ No fork; proceed was correct.

Zone 2 C — propagation proved by RUNNING, ⛔ not inferred

In a worktree with no node_modules, so the prerequisite is genuinely unmet:

• 6 sampled importers before the edit → EXIT=1.
• All 11 after → EXIT=3, and the printed line changed from (Exit code 1 — …) to (Exit code 3, distinct from a finding's 1 — …)in the same runs.

Exit codes captured with cmd > log 2>&1; echo EXIT=$?, ⛔ never through a pipe — which is the very misreading the advisory warns about. Pass-through over all 45 on an installed tree: 43 exit 0; three exceptions each named, each with its own cause, none reaching the changed branch.

Ablation — two mutations, each aimed at a different half of Zone 1.2

Direction predicted before running, mutation proved on disk by anchored counts and blob hash (5c8fad30 vs HEAD's 05668e5b), restore proved by blob equality and an empty git diff HEAD, ⛔ not by a trap firing:

• A — a literal process.exit(1) at the refusal ⇒ self-test red, "the refusal exits through the named constant, never a literal".
• B — a literal put back in the advisory ⇒ self-test red, 3 of 49, including "the advisory carries NO stale spelling of the old code".

⇒ ⭐ Mutation B is exactly the failure Zone 1.2 exists to prevent, and it is now pinned rather than merely promised.

Self-test 41 → 49, which I ran on both trees myself rather than accepting the number.

⛔ And the no-build-leg question is stated rather than skipped: the subject is a plain .mjs executed from source, so node reads the mutated bytes directly and there is no dist preflight to run.

Gates

14 derived, comm -23empty; 12 green, 1 NOT MEASURED (check-test-completeness exit 3 — ⭐ the very class this PR is about, reported correctly by a gate that already implements it). Repo-wide pnpm lint in full, exit 0. skip-changeset applied additively and read back after the size-labeler's later write, confirming it was not stripped — a real risk with whole-set label writes and worth having checked.

Three follow-ups, all filed or reported rather than folded in

• scripts/import-prerequisite.mjs ships a 49-case --self-test that no workflow and no package.json script runs — the frame 45 gates inherit #14007 — the frame ships a 49-case --self-test that no workflow and no package.json script runs: the pin for a paragraph 45 gates print is itself unrun. ⭐ And the dev checked why check-self-test-wired is green and correct — its population is scripts CI runs; this is a module gates import. ⇒ Pre-existing, ⛔ not caused here.
• Three PREREQUISITE NOT MET sites still exit 1 after #13983 — the i18n frames, plus a lane doc that keys on the old number #14008 — three PREREQUISITE NOT MET sites still exit 1, and moving them would falsify .claude/skills/pm-dispatch/references/lanes/services.md:22 — a governed surface. ⭐ Correctly left alone: an AI seat cannot arm that PR, so folding it in would have made this one unarmable.
• import-prerequisite.mjs prints a node scripts/NAME.mjs command that does not exist, for the three importers under packages/lint/scripts/ #13826 — open, unassigned, same file; untouched by this diff but now needs a rebase on this PR. ⇒ Noted for whoever takes it.

Fixes#13983

scripts/import-prerequisite.mjs — the shared PREREQUISITE NOT MET frame that 45 gates import (42 under scripts/**, 3 under packages/lint/scripts/**) — refused with exit 1 and told all 45 so in the advisory they inherit verbatim. Sibling gates answer the same two words with 3. This aligns the frame to 3, and moves the number and the printed advisory in one stroke.

What changed (one file, 106 insertions / 8 deletions)

• EXIT_PREREQUISITE_NOT_MET = 3 and EXIT_FINDINGS = 1, named and exported, mirroring PR Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982's vocabulary so the four files read alike.
• reportPrerequisiteNotMet exits the constant instead of a literal 1.
• The inherited advisory now reads (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe: — the same phrasing check-type-check-coverage.mjs prints since Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982.
• The doc comment that argued for 1 is replaced by the argument for 3, with the true half of the counter-argument kept (below). The header's own "exit 1 and exit 1 are the same reading" paragraph now says how the frame answers that.
• Self-test: 41 cases to 49, including a pin over the function bodies plus two negative controls.

⛔ Untouched, per the card: the refusal itself, its wording, when it fires, every threshold, and a real verdict's exit 1.

The counter-argument in the source, answered — and its true half conceded

The frame said: "a second failure code would be a new contract nobody asked for."

The half that holds, and it is not glossed over: there is ZERO mechanical benefit today. Every consumer of these 45 gates treats any non-zero as failure. Measured, not assumed — see the Zone 1.3 census below. Nothing in CI behaves differently after this PR, and the delivery does not pretend otherwise.

The half that does not hold: the contract already exists.PREREQUISITE NOT MET is already exit 3 in five places on main:

site	constant
scripts/check-test-completeness.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (argued at length in its header)
scripts/check-dual-build-cjs-loads.mjs	EXIT_PREREQ = 3
scripts/check-type-check-coverage.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (PR #13982)
scripts/pm/check-half-states.mjs	export const EXIT_PREREQUISITE_NOT_MET = 3
scripts/pm/ci-failure.mjs	imports the row above rather than re-picking it

And it is read by number, not merely declared: .github/workflows/half-state-patrol.yml branches on exitCode === 3 to render "PREREQUISITE NOT MET — the runner could not reach the board" instead of "SWEEP FAILED". So this PR adds no contract; it stops the largest inheritance surface in the repo from contradicting one that six sites already write and one workflow already consumes.

Zone 1.3 — does any consumer key on 1 today? Measured: NO

The card's blocking pre-work item. Four channels, all of main:

1. Root package.json — every one of the 33 aliases for these gates is an && chain. Zero / non-zero only.
2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files. Three (required-set-patrol.yml, half-state-patrol.yml, check-links.yml) capture a code; only required-set-patrol.yml runs an importing gate (check-required-contexts.mjs), and it branches on == '0' / != '0' and nothing finer. half-state-patrol.yml keys on 3, for a script that is not an importer.
3. The 45 importers themselves — none imports reportPrerequisiteNotMet or classifyImportFailure; all 45 import only requireDependency / requireDefaultExport, whose refusal path exits before returning. The status === 1 assertions that do exist in importer self-tests (check-cli-test-child-env, check-step-collectors, ts-parse, check-plugin-teardown-shape) all pin those gates' own findings path, never the prerequisite path.
4. Prose — the one document keyed on a prerequisite exiting 1 is a pm-dispatch lane reference, and it names check:i18n, which refuses through a different frame (cli-build-prerequisite.mjs) this PR does not touch. It stays true. Filed as a follow-up finding instead.

Verification

Union run at 9370edc74, which is this branch's head.

Propagation, measured rather than inferred (the frame exiting 3 is not proof an importer does). Eleven importing gates, run in a worktree with no node_modules so the prerequisite was genuinely unmet, exit captured with no pipe in between:

BEFORE (c0770d0b7) AFTER (9370edc74)
EXIT=1 scripts/check-doc-frontmatter EXIT=3 scripts/check-doc-frontmatter
EXIT=1 scripts/check-ci-filter-parity EXIT=3 scripts/check-ci-filter-parity
EXIT=1 scripts/check-engine-double-contract EXIT=3 (same)
EXIT=1 scripts/check-required-contexts EXIT=3 (same)
EXIT=1 scripts/check-aggregator-roster EXIT=3 (same)
EXIT=1 packages/lint/scripts/check-reference-carrier-shape EXIT=3 (same)
+ check-doc-anchors, check-override-consistency,
check-route-envelope, ts-parse,
packages/lint/scripts/check-doc-security-posture — all EXIT=3

and the advisory moved with it, in the same run:

- (Exit code 1 — capture it BEFORE any pipe:
+ (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

mutation	self-test
control (HEAD)	exit 0, 49/49 pass
process.exit(1) written back into the refusal	exit 1 — "the refusal exits through the named constant, never a literal"
the advisory spells a literal code again	exit 1 — three cases red, including "the advisory carries NO stale spelling of the old code"

The two negative controls in the self-test are why those pins are measurements rather than tautologies: each predicate is also run against a never-called function that does the forbidden thing, and must see it.

Derived gate families — node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack at 9370edc74, 14 families, comm -23 (derived minus run) empty:

• 12 green: check:agent-test-spelling · check:bash32-floor · check:cli-command-ids · check:cross-package-test-inputs · check:entry-guard · check:parse-guard · check:pnpm-filter-targets · check:watch-hint-literal · node scripts/check-ci-filter-parity.mjs · node scripts/check-cross-package-test-inputs.mjs · node scripts/check-shard-attestation.mjs · both @objectstack/lint families (after building @objectstack/formula and @objectstack/lint).
• node scripts/check-test-completeness.mjs — NOT MEASURED, exit 3, which is that gate's own documented local reading when no turbo run test log is passed: "⛔ It is not a red, and there is nothing here to fix."

Also run: pnpm lint (eslint . --no-inline-config, the whole repo, not a narrowed subset) — exit 0. pnpm check:nul-bytes — OK over 7666 tracked files. node scripts/import-prerequisite.mjs --self-test — 49/49.

Changeset

None. scripts/** matches no workspace publish glob and the root package is private, so this PR publishes nothing; skip-changeset is applied additively.

Governed surfaces

None. The diff is one file, scripts/import-prerequisite.mjs — no docs/adr/**, no .claude/**, no skills/**, no AGENTS.md, no CLAUDE.md.

Neighbour of [finding] packages/cli/scripts/check-app-nav-i18n.mjs prerequisite banner says echo "EXIT=$?" but never says BEFORE any pipe, and names no shape #13825, which covers the same banner's wording.

Related, not addressed here: #13826 is open against this same file (the printed node scripts/NAME.mjs command is wrong for the three packages/lint importers). It is untouched by this diff — different line — but whoever takes it will want to rebase.

ACCEPT — domain:devx execution PM seat (#6023), session session_01Pk26oZ12t5N1hwGW1m1MgC. Central claims re-run by this seat, ⛔ not read off the report.

⭐⭐ Zone 1.2 was answered more strongly than it was asked

I ruled that the exit code and the printed advisory must change in one stroke, because a stale advisory inherited by every importer is worse than the status quo. The delivery makes the second stroke impossible: the advisory is now interpolated from the constants, ⛔ not respelled.

:504 ` (Exit code ${EXIT_PREREQUISITE_NOT_MET}, distinct from a finding's ${EXIT_FINDINGS} — capture it BEFORE any pipe:\n`

⇒ The text cannot diverge from the number, because it is the number. ⭐ A rule I stated as a discipline was answered as a structure, which is the better answer.

⚠️ And a check I ran that looked like a violation and was not: grep "Exit code 1" on the new file returns a hit. It is :737controlLiteralAdvisory — a never-called function that deliberately spells the old literal, so the pin at :751 (!/Exit code 1\b/.test(advisory)) is proven able to fire. That is the negative-control shape from PR #13982, and there are two of them here. ⛔ I checked before reporting it, which is the only reason this paragraph says "control" and not "defect".

⭐⭐ The counter-argument in the source is not merely outvoted — it is FALSIFIED

The source argued for 1: "a second failure code would be a new contract nobody asked for." Triage answered "the contract already exists, in three gates". The dev found something better, and I verified it on origin/main:

.github/workflows/half-state-patrol.yml:285: const kind = exitCode === 3

⇒ ⭐ A workflow already branches on the number. The contract is not declared-only prose that a reader might misread — it is mechanically read, today, by a live workflow. That moves the case off "consistency is nicer" and onto "one side of a read contract is wrong."

And the count is bigger than either the card or triage had: six sites hold 3, not three — check-test-completeness, check-dual-build-cjs-loads, check-type-check-coverage, plus pm/check-half-states (which exports the constant), pm/ci-failure and pm/check-clause2-carriers (which import rather than re-pick).

⚠️ ⭐ And the concession survives anyway, correctly. The dev still records — in the source, the commit message and the PR body — that there is zero mechanical CI benefit for these 45 gates, because no consumer keys on their exit. Both halves are true at once, and keeping the weaker one on the record is what makes the stronger one credible.

The card's own count was low — corrected upward

The card said "20+ gates". The dev measured 45. My independent count of files mentioning the module on origin/main is 47 (44 under scripts/**, 3 under packages/lint/**); the dev's narrower figure counts actual importers of the two functions, so the two readings differ by 2 and agree on the magnitude. ⛔ I report both rather than adopting one — either way it is more than double the card's number, and the blast radius argument gets stronger, not weaker.

Zone 1.3 — the fork question was measured, and it did not fire

No consumer keys on 1. ⇒ No fork; proceed was correct.

In a worktree with no node_modules, so the prerequisite is genuinely unmet:

• 6 sampled importers before the edit → EXIT=1.
• All 11 after → EXIT=3, and the printed line changed from (Exit code 1 — …) to (Exit code 3, distinct from a finding's 1 — …)in the same runs.

2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files.

and the advisory moved with it, in the same run:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

• node scripts/check-test-completeness.mjs — NOT MEASURED, exit 3, which is that gate's own documented local reading when no turbo run test log is passed: "⛔ It is not a red, and there is nothing here to fix."

Also run: pnpm lint (eslint . --no-inline-config, the whole repo, not a narrowed subset) — exit 0. pnpm check:nul-bytes — OK over 7666 tracked files. node scripts/import-prerequisite.mjs --self-test — 49/49.

Changeset

None. scripts/** matches no workspace publish glob and the root package is private, so this PR publishes nothing; skip-changeset is applied additively.

Governed surfaces

None. The diff is one file, scripts/import-prerequisite.mjs — no docs/adr/**, no .claude/**, no skills/**, no AGENTS.md, no CLAUDE.md.

Neighbour of [finding] packages/cli/scripts/check-app-nav-i18n.mjs prerequisite banner says echo "EXIT=$?" but never says BEFORE any pipe, and names no shape #13825, which covers the same banner's wording.

Related, not addressed here: #13826 is open against this same file (the printed node scripts/NAME.mjs command is wrong for the three packages/lint importers). It is untouched by this diff — different line — but whoever takes it will want to rebase.

ACCEPT — domain:devx execution PM seat (#6023), session session_01Pk26oZ12t5N1hwGW1m1MgC. Central claims re-run by this seat, ⛔ not read off the report.

⭐⭐ Zone 1.2 was answered more strongly than it was asked

I ruled that the exit code and the printed advisory must change in one stroke, because a stale advisory inherited by every importer is worse than the status quo. The delivery makes the second stroke impossible: the advisory is now interpolated from the constants, ⛔ not respelled.

:504 ` (Exit code ${EXIT_PREREQUISITE_NOT_MET}, distinct from a finding's ${EXIT_FINDINGS} — capture it BEFORE any pipe:\n`

⇒ The text cannot diverge from the number, because it is the number. ⭐ A rule I stated as a discipline was answered as a structure, which is the better answer.

⚠️ And a check I ran that looked like a violation and was not: grep "Exit code 1" on the new file returns a hit. It is :737controlLiteralAdvisory — a never-called function that deliberately spells the old literal, so the pin at :751 (!/Exit code 1\b/.test(advisory)) is proven able to fire. That is the negative-control shape from PR #13982, and there are two of them here. ⛔ I checked before reporting it, which is the only reason this paragraph says "control" and not "defect".

⭐⭐ The counter-argument in the source is not merely outvoted — it is FALSIFIED

The source argued for 1: "a second failure code would be a new contract nobody asked for." Triage answered "the contract already exists, in three gates". The dev found something better, and I verified it on origin/main:

.github/workflows/half-state-patrol.yml:285: const kind = exitCode === 3

⇒ ⭐ A workflow already branches on the number. The contract is not declared-only prose that a reader might misread — it is mechanically read, today, by a live workflow. That moves the case off "consistency is nicer" and onto "one side of a read contract is wrong."

And the count is bigger than either the card or triage had: six sites hold 3, not three — check-test-completeness, check-dual-build-cjs-loads, check-type-check-coverage, plus pm/check-half-states (which exports the constant), pm/ci-failure and pm/check-clause2-carriers (which import rather than re-pick).

⚠️ ⭐ And the concession survives anyway, correctly. The dev still records — in the source, the commit message and the PR body — that there is zero mechanical CI benefit for these 45 gates, because no consumer keys on their exit. Both halves are true at once, and keeping the weaker one on the record is what makes the stronger one credible.

The card's own count was low — corrected upward

The card said "20+ gates". The dev measured 45. My independent count of files mentioning the module on origin/main is 47 (44 under scripts/**, 3 under packages/lint/**); the dev's narrower figure counts actual importers of the two functions, so the two readings differ by 2 and agree on the magnitude. ⛔ I report both rather than adopting one — either way it is more than double the card's number, and the blast radius argument gets stronger, not weaker.

Zone 1.3 — the fork question was measured, and it did not fire

No consumer keys on 1. ⇒ No fork; proceed was correct.

Zone 2 C — propagation proved by RUNNING, ⛔ not inferred

In a worktree with no node_modules, so the prerequisite is genuinely unmet:

• 6 sampled importers before the edit → EXIT=1.
• All 11 after → EXIT=3, and the printed line changed from (Exit code 1 — …) to (Exit code 3, distinct from a finding's 1 — …)in the same runs.

Exit codes captured with cmd > log 2>&1; echo EXIT=$?, ⛔ never through a pipe — which is the very misreading the advisory warns about. Pass-through over all 45 on an installed tree: 43 exit 0; three exceptions each named, each with its own cause, none reaching the changed branch.

Ablation — two mutations, each aimed at a different half of Zone 1.2

Direction predicted before running, mutation proved on disk by anchored counts and blob hash (5c8fad30 vs HEAD's 05668e5b), restore proved by blob equality and an empty git diff HEAD, ⛔ not by a trap firing:

• A — a literal process.exit(1) at the refusal ⇒ self-test red, "the refusal exits through the named constant, never a literal".
• B — a literal put back in the advisory ⇒ self-test red, 3 of 49, including "the advisory carries NO stale spelling of the old code".

⇒ ⭐ Mutation B is exactly the failure Zone 1.2 exists to prevent, and it is now pinned rather than merely promised.

Self-test 41 → 49, which I ran on both trees myself rather than accepting the number.

⛔ And the no-build-leg question is stated rather than skipped: the subject is a plain .mjs executed from source, so node reads the mutated bytes directly and there is no dist preflight to run.

Gates

14 derived, comm -23empty; 12 green, 1 NOT MEASURED (check-test-completeness exit 3 — ⭐ the very class this PR is about, reported correctly by a gate that already implements it). Repo-wide pnpm lint in full, exit 0. skip-changeset applied additively and read back after the size-labeler's later write, confirming it was not stripped — a real risk with whole-set label writes and worth having checked.

Three follow-ups, all filed or reported rather than folded in

• scripts/import-prerequisite.mjs ships a 49-case --self-test that no workflow and no package.json script runs — the frame 45 gates inherit #14007 — the frame ships a 49-case --self-test that no workflow and no package.json script runs: the pin for a paragraph 45 gates print is itself unrun. ⭐ And the dev checked why check-self-test-wired is green and correct — its population is scripts CI runs; this is a module gates import. ⇒ Pre-existing, ⛔ not caused here.
• Three PREREQUISITE NOT MET sites still exit 1 after #13983 — the i18n frames, plus a lane doc that keys on the old number #14008 — three PREREQUISITE NOT MET sites still exit 1, and moving them would falsify .claude/skills/pm-dispatch/references/lanes/services.md:22 — a governed surface. ⭐ Correctly left alone: an AI seat cannot arm that PR, so folding it in would have made this one unarmable.
• import-prerequisite.mjs prints a node scripts/NAME.mjs command that does not exist, for the three importers under packages/lint/scripts/ #13826 — open, unassigned, same file; untouched by this diff but now needs a rebase on this PR. ⇒ Noted for whoever takes it.

Fixes#13983

scripts/import-prerequisite.mjs — the shared PREREQUISITE NOT MET frame that 45 gates import (42 under scripts/**, 3 under packages/lint/scripts/**) — refused with exit 1 and told all 45 so in the advisory they inherit verbatim. Sibling gates answer the same two words with 3. This aligns the frame to 3, and moves the number and the printed advisory in one stroke.

What changed (one file, 106 insertions / 8 deletions)

• EXIT_PREREQUISITE_NOT_MET = 3 and EXIT_FINDINGS = 1, named and exported, mirroring PR Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982's vocabulary so the four files read alike.
• reportPrerequisiteNotMet exits the constant instead of a literal 1.
• The inherited advisory now reads (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe: — the same phrasing check-type-check-coverage.mjs prints since Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982.
• The doc comment that argued for 1 is replaced by the argument for 3, with the true half of the counter-argument kept (below). The header's own "exit 1 and exit 1 are the same reading" paragraph now says how the frame answers that.
• Self-test: 41 cases to 49, including a pin over the function bodies plus two negative controls.

⛔ Untouched, per the card: the refusal itself, its wording, when it fires, every threshold, and a real verdict's exit 1.

The counter-argument in the source, answered — and its true half conceded

The frame said: "a second failure code would be a new contract nobody asked for."

The half that holds, and it is not glossed over: there is ZERO mechanical benefit today. Every consumer of these 45 gates treats any non-zero as failure. Measured, not assumed — see the Zone 1.3 census below. Nothing in CI behaves differently after this PR, and the delivery does not pretend otherwise.

The half that does not hold: the contract already exists.PREREQUISITE NOT MET is already exit 3 in five places on main:

site	constant
scripts/check-test-completeness.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (argued at length in its header)
scripts/check-dual-build-cjs-loads.mjs	EXIT_PREREQ = 3
scripts/check-type-check-coverage.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (PR #13982)
scripts/pm/check-half-states.mjs	export const EXIT_PREREQUISITE_NOT_MET = 3
scripts/pm/ci-failure.mjs	imports the row above rather than re-picking it

And it is read by number, not merely declared: .github/workflows/half-state-patrol.yml branches on exitCode === 3 to render "PREREQUISITE NOT MET — the runner could not reach the board" instead of "SWEEP FAILED". So this PR adds no contract; it stops the largest inheritance surface in the repo from contradicting one that six sites already write and one workflow already consumes.

Zone 1.3 — does any consumer key on 1 today? Measured: NO

The card's blocking pre-work item. Four channels, all of main:

1. Root package.json — every one of the 33 aliases for these gates is an && chain. Zero / non-zero only.
2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files. Three (required-set-patrol.yml, half-state-patrol.yml, check-links.yml) capture a code; only required-set-patrol.yml runs an importing gate (check-required-contexts.mjs), and it branches on == '0' / != '0' and nothing finer. half-state-patrol.yml keys on 3, for a script that is not an importer.
3. The 45 importers themselves — none imports reportPrerequisiteNotMet or classifyImportFailure; all 45 import only requireDependency / requireDefaultExport, whose refusal path exits before returning. The status === 1 assertions that do exist in importer self-tests (check-cli-test-child-env, check-step-collectors, ts-parse, check-plugin-teardown-shape) all pin those gates' own findings path, never the prerequisite path.
4. Prose — the one document keyed on a prerequisite exiting 1 is a pm-dispatch lane reference, and it names check:i18n, which refuses through a different frame (cli-build-prerequisite.mjs) this PR does not touch. It stays true. Filed as a follow-up finding instead.

Verification

Union run at 9370edc74, which is this branch's head.

Propagation, measured rather than inferred (the frame exiting 3 is not proof an importer does). Eleven importing gates, run in a worktree with no node_modules so the prerequisite was genuinely unmet, exit captured with no pipe in between:

BEFORE (c0770d0b7) AFTER (9370edc74)
EXIT=1 scripts/check-doc-frontmatter EXIT=3 scripts/check-doc-frontmatter
EXIT=1 scripts/check-ci-filter-parity EXIT=3 scripts/check-ci-filter-parity
EXIT=1 scripts/check-engine-double-contract EXIT=3 (same)
EXIT=1 scripts/check-required-contexts EXIT=3 (same)
EXIT=1 scripts/check-aggregator-roster EXIT=3 (same)
EXIT=1 packages/lint/scripts/check-reference-carrier-shape EXIT=3 (same)
+ check-doc-anchors, check-override-consistency,
check-route-envelope, ts-parse,
packages/lint/scripts/check-doc-security-posture — all EXIT=3

and the advisory moved with it, in the same run:

- (Exit code 1 — capture it BEFORE any pipe:
+ (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

mutation	self-test
control (HEAD)	exit 0, 49/49 pass
process.exit(1) written back into the refusal	exit 1 — "the refusal exits through the named constant, never a literal"
the advisory spells a literal code again	exit 1 — three cases red, including "the advisory carries NO stale spelling of the old code"

The two negative controls in the self-test are why those pins are measurements rather than tautologies: each predicate is also run against a never-called function that does the forbidden thing, and must see it.

Derived gate families — node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack at 9370edc74, 14 families, comm -23 (derived minus run) empty:

• node scripts/check-test-completeness.mjs — NOT MEASURED, exit 3, which is that gate's own documented local reading when no turbo run test log is passed: "⛔ It is not a red, and there is nothing here to fix."

The counter-argument in the source, answered — and its true half conceded

The frame said: "a second failure code would be a new contract nobody asked for."

The half that holds, and it is not glossed over: there is ZERO mechanical benefit today. Every consumer of these 45 gates treats any non-zero as failure. Measured, not assumed — see the Zone 1.3 census below. Nothing in CI behaves differently after this PR, and the delivery does not pretend otherwise.

The half that does not hold: the contract already exists.PREREQUISITE NOT MET is already exit 3 in five places on main:

site	constant
scripts/check-test-completeness.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (argued at length in its header)
scripts/check-dual-build-cjs-loads.mjs	EXIT_PREREQ = 3
scripts/check-type-check-coverage.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (PR #13982)
scripts/pm/check-half-states.mjs	export const EXIT_PREREQUISITE_NOT_MET = 3
scripts/pm/ci-failure.mjs	imports the row above rather than re-picking it

And it is read by number, not merely declared: .github/workflows/half-state-patrol.yml branches on exitCode === 3 to render "PREREQUISITE NOT MET — the runner could not reach the board" instead of "SWEEP FAILED". So this PR adds no contract; it stops the largest inheritance surface in the repo from contradicting one that six sites already write and one workflow already consumes.

Zone 1.3 — does any consumer key on 1 today? Measured: NO

The card's blocking pre-work item. Four channels, all of main:

1. Root package.json — every one of the 33 aliases for these gates is an && chain. Zero / non-zero only.
2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files. Three (required-set-patrol.yml, half-state-patrol.yml, check-links.yml) capture a code; only required-set-patrol.yml runs an importing gate (check-required-contexts.mjs), and it branches on == '0' / != '0' and nothing finer. half-state-patrol.yml keys on 3, for a script that is not an importer.
3. The 45 importers themselves — none imports reportPrerequisiteNotMet or classifyImportFailure; all 45 import only requireDependency / requireDefaultExport, whose refusal path exits before returning. The status === 1 assertions that do exist in importer self-tests (check-cli-test-child-env, check-step-collectors, ts-parse, check-plugin-teardown-shape) all pin those gates' own findings path, never the prerequisite path.
4. Prose — the one document keyed on a prerequisite exiting 1 is a pm-dispatch lane reference, and it names check:i18n, which refuses through a different frame (cli-build-prerequisite.mjs) this PR does not touch. It stays true. Filed as a follow-up finding instead.

Verification

Union run at 9370edc74, which is this branch's head.

Propagation, measured rather than inferred (the frame exiting 3 is not proof an importer does). Eleven importing gates, run in a worktree with no node_modules so the prerequisite was genuinely unmet, exit captured with no pipe in between:

BEFORE (c0770d0b7) AFTER (9370edc74)
EXIT=1 scripts/check-doc-frontmatter EXIT=3 scripts/check-doc-frontmatter
EXIT=1 scripts/check-ci-filter-parity EXIT=3 scripts/check-ci-filter-parity
EXIT=1 scripts/check-engine-double-contract EXIT=3 (same)
EXIT=1 scripts/check-required-contexts EXIT=3 (same)
EXIT=1 scripts/check-aggregator-roster EXIT=3 (same)
EXIT=1 packages/lint/scripts/check-reference-carrier-shape EXIT=3 (same)
+ check-doc-anchors, check-override-consistency,
check-route-envelope, ts-parse,
packages/lint/scripts/check-doc-security-posture — all EXIT=3

and the advisory moved with it, in the same run:

- (Exit code 1 — capture it BEFORE any pipe:
+ (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

mutation	self-test
control (HEAD)	exit 0, 49/49 pass
process.exit(1) written back into the refusal	exit 1 — "the refusal exits through the named constant, never a literal"
the advisory spells a literal code again	exit 1 — three cases red, including "the advisory carries NO stale spelling of the old code"

The two negative controls in the self-test are why those pins are measurements rather than tautologies: each predicate is also run against a never-called function that does the forbidden thing, and must see it.

Derived gate families — node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack at 9370edc74, 14 families, comm -23 (derived minus run) empty:

• 12 green: check:agent-test-spelling · check:bash32-floor · check:cli-command-ids · check:cross-package-test-inputs · check:entry-guard · check:parse-guard · check:pnpm-filter-targets · check:watch-hint-literal · node scripts/check-ci-filter-parity.mjs · node scripts/check-cross-package-test-inputs.mjs · node scripts/check-shard-attestation.mjs · both @objectstack/lint families (after building @objectstack/formula and @objectstack/lint).
• node scripts/check-test-completeness.mjs — NOT MEASURED, exit 3, which is that gate's own documented local reading when no turbo run test log is passed: "⛔ It is not a red, and there is nothing here to fix."

Also run: pnpm lint (eslint . --no-inline-config, the whole repo, not a narrowed subset) — exit 0. pnpm check:nul-bytes — OK over 7666 tracked files. node scripts/import-prerequisite.mjs --self-test — 49/49.

Changeset

None. scripts/** matches no workspace publish glob and the root package is private, so this PR publishes nothing; skip-changeset is applied additively.

Neighbour of [finding] packages/cli/scripts/check-app-nav-i18n.mjs prerequisite banner says echo "EXIT=$?" but never says BEFORE any pipe, and names no shape #13825, which covers the same banner's wording.

ACCEPT — domain:devx execution PM seat (#6023), session session_01Pk26oZ12t5N1hwGW1m1MgC. Central claims re-run by this seat, ⛔ not read off the report.

⭐⭐ Zone 1.2 was answered more strongly than it was asked

I ruled that the exit code and the printed advisory must change in one stroke, because a stale advisory inherited by every importer is worse than the status quo. The delivery makes the second stroke impossible: the advisory is now interpolated from the constants, ⛔ not respelled.

:504 ` (Exit code ${EXIT_PREREQUISITE_NOT_MET}, distinct from a finding's ${EXIT_FINDINGS} — capture it BEFORE any pipe:\n`

⇒ The text cannot diverge from the number, because it is the number. ⭐ A rule I stated as a discipline was answered as a structure, which is the better answer.

⚠️ And a check I ran that looked like a violation and was not: grep "Exit code 1" on the new file returns a hit. It is :737controlLiteralAdvisory — a never-called function that deliberately spells the old literal, so the pin at :751 (!/Exit code 1\b/.test(advisory)) is proven able to fire. That is the negative-control shape from PR #13982, and there are two of them here. ⛔ I checked before reporting it, which is the only reason this paragraph says "control" and not "defect".

⭐⭐ The counter-argument in the source is not merely outvoted — it is FALSIFIED

The source argued for 1: "a second failure code would be a new contract nobody asked for." Triage answered "the contract already exists, in three gates". The dev found something better, and I verified it on origin/main:

.github/workflows/half-state-patrol.yml:285: const kind = exitCode === 3

⇒ ⭐ A workflow already branches on the number. The contract is not declared-only prose that a reader might misread — it is mechanically read, today, by a live workflow. That moves the case off "consistency is nicer" and onto "one side of a read contract is wrong."

And the count is bigger than either the card or triage had: six sites hold 3, not three — check-test-completeness, check-dual-build-cjs-loads, check-type-check-coverage, plus pm/check-half-states (which exports the constant), pm/ci-failure and pm/check-clause2-carriers (which import rather than re-pick).

⚠️ ⭐ And the concession survives anyway, correctly. The dev still records — in the source, the commit message and the PR body — that there is zero mechanical CI benefit for these 45 gates, because no consumer keys on their exit. Both halves are true at once, and keeping the weaker one on the record is what makes the stronger one credible.

The card's own count was low — corrected upward

The card said "20+ gates". The dev measured 45. My independent count of files mentioning the module on origin/main is 47 (44 under scripts/**, 3 under packages/lint/**); the dev's narrower figure counts actual importers of the two functions, so the two readings differ by 2 and agree on the magnitude. ⛔ I report both rather than adopting one — either way it is more than double the card's number, and the blast radius argument gets stronger, not weaker.

Zone 1.3 — the fork question was measured, and it did not fire

No consumer keys on 1. ⇒ No fork; proceed was correct.

Zone 2 C — propagation proved by RUNNING, ⛔ not inferred

In a worktree with no node_modules, so the prerequisite is genuinely unmet:

• 6 sampled importers before the edit → EXIT=1.
• All 11 after → EXIT=3, and the printed line changed from (Exit code 1 — …) to (Exit code 3, distinct from a finding's 1 — …)in the same runs.

Exit codes captured with cmd > log 2>&1; echo EXIT=$?, ⛔ never through a pipe — which is the very misreading the advisory warns about. Pass-through over all 45 on an installed tree: 43 exit 0; three exceptions each named, each with its own cause, none reaching the changed branch.

Ablation — two mutations, each aimed at a different half of Zone 1.2

Direction predicted before running, mutation proved on disk by anchored counts and blob hash (5c8fad30 vs HEAD's 05668e5b), restore proved by blob equality and an empty git diff HEAD, ⛔ not by a trap firing:

• A — a literal process.exit(1) at the refusal ⇒ self-test red, "the refusal exits through the named constant, never a literal".
• B — a literal put back in the advisory ⇒ self-test red, 3 of 49, including "the advisory carries NO stale spelling of the old code".

⇒ ⭐ Mutation B is exactly the failure Zone 1.2 exists to prevent, and it is now pinned rather than merely promised.

Self-test 41 → 49, which I ran on both trees myself rather than accepting the number.

⛔ And the no-build-leg question is stated rather than skipped: the subject is a plain .mjs executed from source, so node reads the mutated bytes directly and there is no dist preflight to run.

Gates

14 derived, comm -23empty; 12 green, 1 NOT MEASURED (check-test-completeness exit 3 — ⭐ the very class this PR is about, reported correctly by a gate that already implements it). Repo-wide pnpm lint in full, exit 0. skip-changeset applied additively and read back after the size-labeler's later write, confirming it was not stripped — a real risk with whole-set label writes and worth having checked.

Three follow-ups, all filed or reported rather than folded in

• Three PREREQUISITE NOT MET sites still exit 1 after #13983 — the i18n frames, plus a lane doc that keys on the old number #14008 — three PREREQUISITE NOT MET sites still exit 1, and moving them would falsify .claude/skills/pm-dispatch/references/lanes/services.md:22 — a governed surface. ⭐ Correctly left alone: an AI seat cannot arm that PR, so folding it in would have made this one unarmable.
• import-prerequisite.mjs prints a node scripts/NAME.mjs command that does not exist, for the three importers under packages/lint/scripts/ #13826 — open, unassigned, same file; untouched by this diff but now needs a rebase on this PR. ⇒ Noted for whoever takes it.

Fixes#13983

scripts/import-prerequisite.mjs — the shared PREREQUISITE NOT MET frame that 45 gates import (42 under scripts/**, 3 under packages/lint/scripts/**) — refused with exit 1 and told all 45 so in the advisory they inherit verbatim. Sibling gates answer the same two words with 3. This aligns the frame to 3, and moves the number and the printed advisory in one stroke.

What changed (one file, 106 insertions / 8 deletions)

• EXIT_PREREQUISITE_NOT_MET = 3 and EXIT_FINDINGS = 1, named and exported, mirroring PR Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982's vocabulary so the four files read alike.
• reportPrerequisiteNotMet exits the constant instead of a literal 1.
• The inherited advisory now reads (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe: — the same phrasing check-type-check-coverage.mjs prints since Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982.
• The doc comment that argued for 1 is replaced by the argument for 3, with the true half of the counter-argument kept (below). The header's own "exit 1 and exit 1 are the same reading" paragraph now says how the frame answers that.
• Self-test: 41 cases to 49, including a pin over the function bodies plus two negative controls.

⛔ Untouched, per the card: the refusal itself, its wording, when it fires, every threshold, and a real verdict's exit 1.

The counter-argument in the source, answered — and its true half conceded

The frame said: "a second failure code would be a new contract nobody asked for."

The half that holds, and it is not glossed over: there is ZERO mechanical benefit today. Every consumer of these 45 gates treats any non-zero as failure. Measured, not assumed — see the Zone 1.3 census below. Nothing in CI behaves differently after this PR, and the delivery does not pretend otherwise.

The half that does not hold: the contract already exists.PREREQUISITE NOT MET is already exit 3 in five places on main:

site	constant
scripts/check-test-completeness.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (argued at length in its header)
scripts/check-dual-build-cjs-loads.mjs	EXIT_PREREQ = 3
scripts/check-type-check-coverage.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (PR #13982)
scripts/pm/check-half-states.mjs	export const EXIT_PREREQUISITE_NOT_MET = 3
scripts/pm/ci-failure.mjs	imports the row above rather than re-picking it

And it is read by number, not merely declared: .github/workflows/half-state-patrol.yml branches on exitCode === 3 to render "PREREQUISITE NOT MET — the runner could not reach the board" instead of "SWEEP FAILED". So this PR adds no contract; it stops the largest inheritance surface in the repo from contradicting one that six sites already write and one workflow already consumes.

Zone 1.3 — does any consumer key on 1 today? Measured: NO

The card's blocking pre-work item. Four channels, all of main:

1. Root package.json — every one of the 33 aliases for these gates is an && chain. Zero / non-zero only.
2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files. Three (required-set-patrol.yml, half-state-patrol.yml, check-links.yml) capture a code; only required-set-patrol.yml runs an importing gate (check-required-contexts.mjs), and it branches on == '0' / != '0' and nothing finer. half-state-patrol.yml keys on 3, for a script that is not an importer.
3. The 45 importers themselves — none imports reportPrerequisiteNotMet or classifyImportFailure; all 45 import only requireDependency / requireDefaultExport, whose refusal path exits before returning. The status === 1 assertions that do exist in importer self-tests (check-cli-test-child-env, check-step-collectors, ts-parse, check-plugin-teardown-shape) all pin those gates' own findings path, never the prerequisite path.
4. Prose — the one document keyed on a prerequisite exiting 1 is a pm-dispatch lane reference, and it names check:i18n, which refuses through a different frame (cli-build-prerequisite.mjs) this PR does not touch. It stays true. Filed as a follow-up finding instead.

Verification

Union run at 9370edc74, which is this branch's head.

Propagation, measured rather than inferred (the frame exiting 3 is not proof an importer does). Eleven importing gates, run in a worktree with no node_modules so the prerequisite was genuinely unmet, exit captured with no pipe in between:

BEFORE (c0770d0b7) AFTER (9370edc74)
EXIT=1 scripts/check-doc-frontmatter EXIT=3 scripts/check-doc-frontmatter
EXIT=1 scripts/check-ci-filter-parity EXIT=3 scripts/check-ci-filter-parity

EXIT=1 scripts/check-required-contexts EXIT=3 (same)

+ check-doc-anchors, check-override-consistency,
check-route-envelope, ts-parse,
packages/lint/scripts/check-doc-security-posture — all EXIT=3

and the advisory moved with it, in the same run:

- (Exit code 1 — capture it BEFORE any pipe:
+ (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

mutation	self-test
control (HEAD)	exit 0, 49/49 pass
process.exit(1) written back into the refusal	exit 1 — "the refusal exits through the named constant, never a literal"
the advisory spells a literal code again	exit 1 — three cases red, including "the advisory carries NO stale spelling of the old code"

The two negative controls in the self-test are why those pins are measurements rather than tautologies: each predicate is also run against a never-called function that does the forbidden thing, and must see it.

• A — a literal process.exit(1) at the refusal ⇒ self-test red, "the refusal exits through the named constant, never a literal".
• B — a literal put back in the advisory ⇒ self-test red, 3 of 49, including "the advisory carries NO stale spelling of the old code".

⇒ ⭐ Mutation B is exactly the failure Zone 1.2 exists to prevent, and it is now pinned rather than merely promised.

Self-test 41 → 49, which I ran on both trees myself rather than accepting the number.

⛔ And the no-build-leg question is stated rather than skipped: the subject is a plain .mjs executed from source, so node reads the mutated bytes directly and there is no dist preflight to run.

Gates

14 derived, comm -23empty; 12 green, 1 NOT MEASURED (check-test-completeness exit 3 — ⭐ the very class this PR is about, reported correctly by a gate that already implements it). Repo-wide pnpm lint in full, exit 0. skip-changeset applied additively and read back after the size-labeler's later write, confirming it was not stripped — a real risk with whole-set label writes and worth having checked.

Three follow-ups, all filed or reported rather than folded in

• scripts/import-prerequisite.mjs ships a 49-case --self-test that no workflow and no package.json script runs — the frame 45 gates inherit #14007 — the frame ships a 49-case --self-test that no workflow and no package.json script runs: the pin for a paragraph 45 gates print is itself unrun. ⭐ And the dev checked why check-self-test-wired is green and correct — its population is scripts CI runs; this is a module gates import. ⇒ Pre-existing, ⛔ not caused here.
• Three PREREQUISITE NOT MET sites still exit 1 after #13983 — the i18n frames, plus a lane doc that keys on the old number #14008 — three PREREQUISITE NOT MET sites still exit 1, and moving them would falsify .claude/skills/pm-dispatch/references/lanes/services.md:22 — a governed surface. ⭐ Correctly left alone: an AI seat cannot arm that PR, so folding it in would have made this one unarmable.
• import-prerequisite.mjs prints a node scripts/NAME.mjs command that does not exist, for the three importers under packages/lint/scripts/ #13826 — open, unassigned, same file; untouched by this diff but now needs a rebase on this PR. ⇒ Noted for whoever takes it.

Previous rounds recorded this as "the MCP write rate limit" without establishing whose quota it was; now measured.

⛔ Not routed around, and the reason is not merely obedience: REST PATCH {draft:false} returns 200 and does not un-draft the PR — measured previously in this lane. A "successful" REST call here would produce a PR that looks armed and is not, which is worse than waiting.

Fixes#13983

scripts/import-prerequisite.mjs — the shared PREREQUISITE NOT MET frame that 45 gates import (42 under scripts/**, 3 under packages/lint/scripts/**) — refused with exit 1 and told all 45 so in the advisory they inherit verbatim. Sibling gates answer the same two words with 3. This aligns the frame to 3, and moves the number and the printed advisory in one stroke.

What changed (one file, 106 insertions / 8 deletions)

• EXIT_PREREQUISITE_NOT_MET = 3 and EXIT_FINDINGS = 1, named and exported, mirroring PR Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982's vocabulary so the four files read alike.
• reportPrerequisiteNotMet exits the constant instead of a literal 1.
• The inherited advisory now reads (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe: — the same phrasing check-type-check-coverage.mjs prints since Answer every check-type-check-coverage refusal with exit 3, not a finding's 1 #13982.
• The doc comment that argued for 1 is replaced by the argument for 3, with the true half of the counter-argument kept (below). The header's own "exit 1 and exit 1 are the same reading" paragraph now says how the frame answers that.
• Self-test: 41 cases to 49, including a pin over the function bodies plus two negative controls.

⛔ Untouched, per the card: the refusal itself, its wording, when it fires, every threshold, and a real verdict's exit 1.

The counter-argument in the source, answered — and its true half conceded

The frame said: "a second failure code would be a new contract nobody asked for."

The half that holds, and it is not glossed over: there is ZERO mechanical benefit today. Every consumer of these 45 gates treats any non-zero as failure. Measured, not assumed — see the Zone 1.3 census below. Nothing in CI behaves differently after this PR, and the delivery does not pretend otherwise.

The half that does not hold: the contract already exists.PREREQUISITE NOT MET is already exit 3 in five places on main:

site	constant
scripts/check-test-completeness.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (argued at length in its header)
scripts/check-dual-build-cjs-loads.mjs	EXIT_PREREQ = 3
scripts/check-type-check-coverage.mjs	EXIT_PREREQUISITE_NOT_MET = 3 (PR #13982)
scripts/pm/check-half-states.mjs	export const EXIT_PREREQUISITE_NOT_MET = 3
scripts/pm/ci-failure.mjs	imports the row above rather than re-picking it

And it is read by number, not merely declared: .github/workflows/half-state-patrol.yml branches on exitCode === 3 to render "PREREQUISITE NOT MET — the runner could not reach the board" instead of "SWEEP FAILED". So this PR adds no contract; it stops the largest inheritance surface in the repo from contradicting one that six sites already write and one workflow already consumes.

Zone 1.3 — does any consumer key on 1 today? Measured: NO

The card's blocking pre-work item. Four channels, all of main:

1. Root package.json — every one of the 33 aliases for these gates is an && chain. Zero / non-zero only.
2. Workflows — git grep for exit-code branching across .github/workflows/** returns four files. Three (required-set-patrol.yml, half-state-patrol.yml, check-links.yml) capture a code; only required-set-patrol.yml runs an importing gate (check-required-contexts.mjs), and it branches on == '0' / != '0' and nothing finer. half-state-patrol.yml keys on 3, for a script that is not an importer.
3. The 45 importers themselves — none imports reportPrerequisiteNotMet or classifyImportFailure; all 45 import only requireDependency / requireDefaultExport, whose refusal path exits before returning. The status === 1 assertions that do exist in importer self-tests (check-cli-test-child-env, check-step-collectors, ts-parse, check-plugin-teardown-shape) all pin those gates' own findings path, never the prerequisite path.
4. Prose — the one document keyed on a prerequisite exiting 1 is a pm-dispatch lane reference, and it names check:i18n, which refuses through a different frame (cli-build-prerequisite.mjs) this PR does not touch. It stays true. Filed as a follow-up finding instead.

Verification

Union run at 9370edc74, which is this branch's head.

Propagation, measured rather than inferred (the frame exiting 3 is not proof an importer does). Eleven importing gates, run in a worktree with no node_modules so the prerequisite was genuinely unmet, exit captured with no pipe in between:

BEFORE (c0770d0b7) AFTER (9370edc74)
EXIT=1 scripts/check-doc-frontmatter EXIT=3 scripts/check-doc-frontmatter
EXIT=1 scripts/check-ci-filter-parity EXIT=3 scripts/check-ci-filter-parity
EXIT=1 scripts/check-engine-double-contract EXIT=3 (same)
EXIT=1 scripts/check-required-contexts EXIT=3 (same)
EXIT=1 scripts/check-aggregator-roster EXIT=3 (same)
EXIT=1 packages/lint/scripts/check-reference-carrier-shape EXIT=3 (same)
+ check-doc-anchors, check-override-consistency,
check-route-envelope, ts-parse,
packages/lint/scripts/check-doc-security-posture — all EXIT=3

and the advisory moved with it, in the same run:

- (Exit code 1 — capture it BEFORE any pipe:
+ (Exit code 3, distinct from a finding's 1 — capture it BEFORE any pipe:

The workspace-unbuilt and self-reference branches were exercised live too, on an installed-but-unbuilt tree: check-doc-formula-expressions refused with 3 for @objectstack/formula, then for @objectstack/lint, then passed once both were built.

Pass-through path: all 45 importers run on the installed tree. 43 exit 0. check-published-readme-exports exits 1 on its own "160 packages are not built, so this run measured nothing" report; measure-stall-guard-headroom exits 2 on its usage banner (it needs --run); check-query-options-erasure-ratchet hit a local 180s cap and is recorded as NOT MEASURED. None of the three reaches the prerequisite branch this PR changes.

Reverse verification of the new pin (PR #13982's shape). Both mutations applied to the committed implementation, each confirmed on disk before the reading, each restored and the restore proven by blob hash against HEAD plus an empty git diff HEAD:

mutation	self-test
control (HEAD)	exit 0, 49/49 pass
process.exit(1) written back into the refusal	exit 1 — "the refusal exits through the named constant, never a literal"
the advisory spells a literal code again	exit 1 — three cases red, including "the advisory carries NO stale spelling of the old code"

The two negative controls in the self-test are why those pins are measurements rather than tautologies: each predicate is also run against a never-called function that does the forbidden thing, and must see it.

Derived gate families — node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack at 9370edc74, 14 families, comm -23 (derived minus run) empty:

• 12 green: check:agent-test-spelling · check:bash32-floor · check:cli-command-ids · check:cross-package-test-inputs · check:entry-guard · check:parse-guard · check:pnpm-filter-targets · check:watch-hint-literal · node scripts/check-ci-filter-parity.mjs · node scripts/check-cross-package-test-inputs.mjs · node scripts/check-shard-attestation.mjs · both @objectstack/lint families (after building @objectstack/formula and @objectstack/lint).
• node scripts/check-test-completeness.mjs — NOT MEASURED, exit 3, which is that gate's own documented local reading when no turbo run test log is passed: "⛔ It is not a red, and there is nothing here to fix."

Also run: pnpm lint (eslint . --no-inline-config, the whole repo, not a narrowed subset) — exit 0. pnpm check:nul-bytes — OK over 7666 tracked files. node scripts/import-prerequisite.mjs --self-test — 49/49.

Changeset

None. scripts/** matches no workspace publish glob and the root package is private, so this PR publishes nothing; skip-changeset is applied additively.

Governed surfaces

None. The diff is one file, scripts/import-prerequisite.mjs — no docs/adr/**, no .claude/**, no skills/**, no AGENTS.md, no CLAUDE.md.

Neighbour of [finding] packages/cli/scripts/check-app-nav-i18n.mjs prerequisite banner says echo "EXIT=$?" but never says BEFORE any pipe, and names no shape #13825, which covers the same banner's wording.

Related, not addressed here: #13826 is open against this same file (the printed node scripts/NAME.mjs command is wrong for the three packages/lint importers). It is untouched by this diff — different line — but whoever takes it will want to rebase.

ACCEPT — domain:devx execution PM seat (#6023), session session_01Pk26oZ12t5N1hwGW1m1MgC. Central claims re-run by this seat, ⛔ not read off the report.

⭐⭐ Zone 1.2 was answered more strongly than it was asked

I ruled that the exit code and the printed advisory must change in one stroke, because a stale advisory inherited by every importer is worse than the status quo. The delivery makes the second stroke impossible: the advisory is now interpolated from the constants, ⛔ not respelled.

:504 ` (Exit code ${EXIT_PREREQUISITE_NOT_MET}, distinct from a finding's ${EXIT_FINDINGS} — capture it BEFORE any pipe:\n`

⇒ The text cannot diverge from the number, because it is the number. ⭐ A rule I stated as a discipline was answered as a structure, which is the better answer.

⚠️ And a check I ran that looked like a violation and was not: grep "Exit code 1" on the new file returns a hit. It is :737controlLiteralAdvisory — a never-called function that deliberately spells the old literal, so the pin at :751 (!/Exit code 1\b/.test(advisory)) is proven able to fire. That is the negative-control shape from PR #13982, and there are two of them here. ⛔ I checked before reporting it, which is the only reason this paragraph says "control" and not "defect".

⭐⭐ The counter-argument in the source is not merely outvoted — it is FALSIFIED

The source argued for 1: "a second failure code would be a new contract nobody asked for." Triage answered "the contract already exists, in three gates". The dev found something better, and I verified it on origin/main:

.github/workflows/half-state-patrol.yml:285: const kind = exitCode === 3

⇒ ⭐ A workflow already branches on the number. The contract is not declared-only prose that a reader might misread — it is mechanically read, today, by a live workflow. That moves the case off "consistency is nicer" and onto "one side of a read contract is wrong."

And the count is bigger than either the card or triage had: six sites hold 3, not three — check-test-completeness, check-dual-build-cjs-loads, check-type-check-coverage, plus pm/check-half-states (which exports the constant), pm/ci-failure and pm/check-clause2-carriers (which import rather than re-pick).

⚠️ ⭐ And the concession survives anyway, correctly. The dev still records — in the source, the commit message and the PR body — that there is zero mechanical CI benefit for these 45 gates, because no consumer keys on their exit. Both halves are true at once, and keeping the weaker one on the record is what makes the stronger one credible.

The card's own count was low — corrected upward

The card said "20+ gates". The dev measured 45. My independent count of files mentioning the module on origin/main is 47 (44 under scripts/**, 3 under packages/lint/**); the dev's narrower figure counts actual importers of the two functions, so the two readings differ by 2 and agree on the magnitude. ⛔ I report both rather than adopting one — either way it is more than double the card's number, and the blast radius argument gets stronger, not weaker.

Zone 1.3 — the fork question was measured, and it did not fire

No consumer keys on 1. ⇒ No fork; proceed was correct.

Zone 2 C — propagation proved by RUNNING, ⛔ not inferred

In a worktree with no node_modules, so the prerequisite is genuinely unmet:

• 6 sampled importers before the edit → EXIT=1.
• All 11 after → EXIT=3, and the printed line changed from (Exit code 1 — …) to (Exit code 3, distinct from a finding's 1 — …)in the same runs.

Exit codes captured with cmd > log 2>&1; echo EXIT=$?, ⛔ never through a pipe — which is the very misreading the advisory warns about. Pass-through over all 45 on an installed tree: 43 exit 0; three exceptions each named, each with its own cause, none reaching the changed branch.

Ablation — two mutations, each aimed at a different half of Zone 1.2

Direction predicted before running, mutation proved on disk by anchored counts and blob hash (5c8fad30 vs HEAD's 05668e5b), restore proved by blob equality and an empty git diff HEAD, ⛔ not by a trap firing:

• A — a literal process.exit(1) at the refusal ⇒ self-test red, "the refusal exits through the named constant, never a literal".
• B — a literal put back in the advisory ⇒ self-test red, 3 of 49, including "the advisory carries NO stale spelling of the old code".

⇒ ⭐ Mutation B is exactly the failure Zone 1.2 exists to prevent, and it is now pinned rather than merely promised.

Self-test 41 → 49, which I ran on both trees myself rather than accepting the number.

⛔ And the no-build-leg question is stated rather than skipped: the subject is a plain .mjs executed from source, so node reads the mutated bytes directly and there is no dist preflight to run.

Gates

14 derived, comm -23empty; 12 green, 1 NOT MEASURED (check-test-completeness exit 3 — ⭐ the very class this PR is about, reported correctly by a gate that already implements it).
