Why

Goal (Antony): every AntelopeJS guardrails.ratchet.json deleted through verified PRs on campaign/integration. interface-subscriptions had one row left, src/tests/subscriptions-changes.test.ts:225 ("fortnight" as SubscriptionRequest["interval"]). Antony's ruling 1 (2026-10-31) lets a test that feeds a deliberately invalid value to prove a rejection use // @ts-expect-error <reason naming the rejection under test> on that one line, never an as cast, with the suppressions-budget raise approved and listed line by line. This PR applies it and deletes the ratchet. The task named line 231; on campaign/integration 9eebc70 the row is at line 225.

What changed

• src/tests/subscriptions-changes.test.ts: the case "an interval outside the vocabulary" returns the invalid value directly. Its factory gets a Partial<SubscriptionRequest> return type. Without that, the unsuppressed literal type { interval: "fortnight" } leaks into the union Object.entries(INVALID) yields and raises a second error at the CreateSubscription(monthly(payer, overrides(...))) call (line 242), which the one directive cannot cover. The annotation keeps the error on the one property line.
• guardrails.ratchet.json deleted by pnpm exec antelopejs-ratchet --update.
• guardrails.suppressions.json: tsExpectError 0 -> 1.
• Separate commit: pnpm run sync (drops the ratchet step from lefthook.yml, package.json, AGENTS.md).

Suppression budget raise (approved by ruling 1), line by line

file:line	directive	reason it carries
src/tests/subscriptions-changes.test.ts:225	// @ts-expect-error	"fortnight" is outside the interval vocabulary, which CreateSubscription must refuse with InvalidSubscriptionRequestError

This is the only raise. No SAFETY:, no lint directive, no rule-off, no ceiling raise.

Proofs

Ratchet (pnpm exec antelopejs-ratchet --update):

Deleted guardrails.ratchet.json: no debt left. Run antelopejs-sync.
Lowered anti-slop/require-safety-comment-for-type-assertion: 1 -> 0

tsc errors on that line without the directive (cast removed, nothing else changed, tsc -p tsconfig.json --noEmit):

src/tests/subscriptions-changes.test.ts(225,7): error TS2322: Type '"fortnight"' is not assignable to type '"day" | "month" | "year" | "week" | undefined'.

With the directive and the annotation, tsc -p tsconfig.json --noEmit exits 0 (a @ts-expect-error with nothing to suppress would itself be TS2578).

The test still asserts the rejection. The suite is a provider conformance suite, skipped without ANTELOPE_PAYMENT_TEST_METHOD and a payment provider, so it cannot run in this repo. Instead: (1) emitting both the base and the head test file with tsc --removeComments gives byte-identical JS, so the assert.rejects(CreateSubscription(...), InvalidSubscriptionRequestError, label) body and the value passed are unchanged; (2) the library's own ValidateSubscriptionRequest, which a provider calls, on the built dist:

valid -> accepted
fortnight -> rejected: true interval must be one of day, week, month, year

pnpm run checks on the committed head e7bc1fa (node 24.22.2, dist removed first, CI=true, GITHUB_BASE_REF=campaign/integration):

guardrails.suppressions.json: raises `@ts-expect-error` from 0 on the base to 1.
Ceilings only go down. Fix the code, or remove another suppression of the same kind; raising a ceiling needs the operator's approval through the ruleset bypass.
Checks: 7 passed, 1 failed.

The one failure is the approved raise above, so CI cannot be green by design (the check refuses any raise without the operator's ruleset bypass). Ruling 1 approves it, and the PR is landed with LAND_ADMIN=1 (land-one.sh). land-raise.sh does not accept this gate: its gate check matches only SAFETY: raise lines, so it would refuse a @ts-expect-error raise. Every other check passes. pnpm run sync:check is part of those 7 and passes after the sync commit.

api-diff (campaign/tools/api-diff-slot.sh origin/campaign/integration, committed head e7bc1fa):

API: 1 packages, 3 entries unchanged against origin/campaign/integration (committed HEAD).
Runtime API: 1 packages, 2 entries unchanged against origin/campaign/integration (committed HEAD).
| `@ts-expect-error` | 0 | 1 |
| Lint suppressions, all rules | 0 | 0 |
| `SAFETY:` comments | 0 | 0 |
| Lint config rule-offs, all rules | 0 | 0 |

Attention

• The @ts-expect-error line is 140 characters. The formatter and antelopejs-format accept it.
• Local node was 24.22.2 (.nvmrc 24).

Re-verified at e7bc1fa (owner rulings-small-b)

• pnpm run checks rerun from a fresh clone, node 24.22.2, dist removed, CI=true, GITHUB_BASE_REF=campaign/integration: same output as above, Checks: 7 passed, 1 failed., the one failure being the approved @ts-expect-error 0 -> 1 raise. CI's failing job shows the identical [suppressions] block and nothing else.
• Emitting the base and head test files with tsc --removeComments into separate dirs and diff -r gives emit identical, so the assert.rejects(CreateSubscription(...), InvalidSubscriptionRequestError, label) call and the passed value are unchanged.
• Deleting only the directive line makes tsc --noEmit fail with src/tests/subscriptions-changes.test.ts(226,7): error TS2322: Type '"fortnight"' is not assignable to type '"day" | "month" | "year" | "week" | undefined'. (exit 2), so the directive is used and covers exactly that error.
• ValidateSubscriptionRequest on the built dist: month -> accepted, fortnight -> rejected: true interval must be one of day, week, month, year.
• campaign/tools/api-diff-slot.sh origin/campaign/integration at e7bc1fa: API: 1 packages, 3 entries unchanged, Runtime API: 1 packages, 2 entries unchanged, @ts-expect-error 0 -> 1, all other suppression rows 0 -> 0.

e7bc1fa: PASS+NOTES

Independent verifier, fresh clone, node 24.22.2, base campaign/integration 9eebc70. Judged against ruling 1 (2026-10-31).

CI is red only on the approved budget raise. That is the single failure, in CI's log and in local pnpm run checks. This PR needs LAND_ADMIN=1.

Ruling 1

Check	Result
Directive reason names the rejection	Yes. src/tests/subscriptions-changes.test.ts:225: "fortnight" is outside the interval vocabulary, which CreateSubscription must refuse with InvalidSubscriptionRequestError
No as cast	Yes. The only as in the src diff is the removed line
Test file only, one line	Yes. It is the only directive, SAFETY: or @ts-ignore in src
Rejection still asserted	Yes. assert.rejects(CreateSubscription(monthly(payer, overrides(Date.now())), key()), InvalidSubscriptionRequestError, label) is untouched
Directive removed	tsc --noEmit exit 2 with one error: src/tests/subscriptions-changes.test.ts(225,7): error TS2322: Type '"fortnight"' is not assignable to type '"day" | "month" | "year" | "week" | undefined'.
Compiled output equals base	tsc --removeComments at base and head, diff -r excluding maps: all 10 .js and 10 .d.ts identical. Only subscriptions-changes.test.js.map differs, because the lines moved
Library rejects the value	ValidateSubscriptionRequest on built dist: month -> accepted, fortnight -> threw InvalidSubscriptionRequestError interval must be one of day, week, month, year

Ratchet and budget

• guardrails.ratchet.json is deleted. Lint measure at head: 0 rows.
• guardrails.suppressions.json: tsExpectError 0 -> 1 is the only change. The body lists it line by line, and line 225 is correct.
• api-diff through api-diff-slot.sh origin/campaign/integration: API 3 entries unchanged, Runtime API 2 entries unchanged, @ts-expect-error 0 -> 1, every other suppression row 0 -> 0.
• The rest of the diff is sync output (lefthook.yml, package.json scripts, AGENTS.md), and sync:check passes. No pack or interface range changed.

The single failure

Local pnpm run checks (dist removed, CI=true, GITHUB_BASE_REF=campaign/integration) and CI run 41194499177, job ci / Node .nvmrc, "Run checks", print the same block:

[suppressions]
guardrails.suppressions.json: raises `@ts-expect-error` from 0 on the base to 1.
Ceilings only go down. Fix the code, or remove another suppression of the same kind; raising a ceiling needs the operator's approval through the ruleset bypass.
Checks: 7 passed, 1 failed.

• ci / checks and checks fail only as aggregators. Their sole step is exit 1.
• "Skill eval, offline" was skipped after the failure. It would not have evaluated anything: antelopeJs.skills is ["./skills"], the step exits 0 when that directory has no diff, and this PR has none.

Notes (cosmetic, not blocking)

• The body's "Re-verified" section and the hand-back give the no-directive error at (226,7). Deleting the directive line gives (225,7), as the body's earlier Proofs section says.
• The same section says diff -r gives emit identical. That holds for .js and .d.ts. The repo's sourceMap: true makes the one map differ.

Attention

• The conformance suite skips without a payment provider, so the rejection test does not run in this repo (as the body says). The proof is the identical emit plus the validator run above.
