Finishes quest/m2/api-shape/auth-sign.md.

Summary

@moq/auth's Key.sign and KeySet.sign take exactly Claims, as Rust's sign(&Claims) does, so each role has one spelling. The legacy put/get input is refused instead of accepted. Tokens written are unchanged: a subtree grant is still written as put/get when that says the same thing, so older verifiers accept it, and verify still reads legacy tokens.

Public API

• Key.sign(key: Key, claims: Claims): the input is the decoded Claims that verify returns.
• KeySet.sign(set: KeySet, claims: Claims): same input.
• api/index.api.md updated for both.

Impact

• Breaking (!): Key.sign and KeySet.sign no longer accept put/get and now refuse them with an error. Migrate by passing publish/subscribe roles, as in Claims.
• Breaking (!): root is required in the TypeScript input (it was optional). The wire still defaults an absent root to "", so a top-level scope passes root: "". No repository caller omits it.
• Wire: none.

Choices made

• Runtime refusal, not just a type change. Untyped callers could still pass put/get, so nestRates throws on them. The error is loud and early, as the rules require.
• KeySet.sign typed as Claims directly, not Parameters<typeof Key.sign>[1]. The indirection renders in the API report as the old shape, which would show put/get in the public contract.
• root stays required. The spec asks for exactly Claims, and Claims.root is required. Keeping sign optional-root would make its input differ from Claims.
• Quest removed: its file is deleted and the epic README link dropped.

Overlap

moq-dev/moq#8295 (quest/m2/js-time-types) also edits js/auth/src/key.ts and key.test.ts, but only at wall() call sites in verify and the test fixtures. This PR touches sign and its sign tests. The hunks are separate, so the second PR to land should merge cleanly. It is not the same change.

Checks

• bun test in js/auth: 168 pass, 0 fail.
• tsc --noEmit for js/auth: pass.
• workspace.py check for the changed packages and their dependents: pass.
• biome check on the four changed source files: pass.
• API reports regenerated with MOQ_API_REPORT=update and rebuilt: only the sign signatures changed.
• quest check: 590 documents ok.

Reviewed changes

This run reviewed the ready-for-review revision of refactor(js)!: Key.sign takes exactly Claims at d4e9ca1, and verified it locally (bun test js/auth/src: 168 pass; tsc --noEmit for the package: clean).

• Key.sign narrowed to Claims — js/auth/src/key.ts now declares sign(key: Key, claims: Claims), so the decoded Claims that verify returns is the only typed input, and root is required again (matching release; the wire still defaults an absent root to "").
• Legacy grants refused at runtime — nestRates in js/auth/src/wire.ts throws on put/get before the schema reparse, so untyped callers cannot slip the old spelling past the type narrowing. sign is its only caller.
• KeySet.sign mirrored — js/auth/src/set.ts takes Claims directly instead of Parameters<typeof Key.sign>[1], so the generated API report shows Claims rather than the removed input shape.
• Tokens unchanged — subtree grants are still written as legacy put/get and verify still reads legacy tokens, both covered by existing tests.
• Tests and quest bookkeeping — the legacy-input test now asserts the refusal for in-scope and out-of-scope grants; the completed quest file and its epic README row are removed with no dangling references.

Automated review by review (OpenAI)

Reviewed head: d4e9ca1

No actionable defects found. The direction is sound: both signing APIs accept decoded Claims, legacy input is rejected before schema parsing and scope checks, and legacy token verification/encoding remains separate and unchanged. Reviewed the changed source, Claims transforms, signing callers, API signatures, and compatibility/scope/rate round-trip tests.

Verification limits: GitHub-only source review; I did not execute builds or tests. The head's Check workflow was still in progress at publication.

Walkthrough

Key.sign and KeySet.sign now accept Claims. Signing rejects claims that contain legacy put or get fields. Tests check that Key.sign rejects legacy put grants both inside and outside the configured scope. The API-shape README entry and proposal document for the planned input change were removed.

Merge Risk: Minimal · up to d4e9c

The signing API accepts canonical Claims and rejects legacy input. No merge-blocking defect remains; adding a get-only rejection test would improve regression coverage.

813-816: Trivial · Functional Correctness · Low value

Test rejection of a get-only grant.

The rejection test checks only put. If the get guard is removed, the parser can accept a get-only grant and the tests will not detect it.

Suggested test

 	const outside = { root: "demo", put: ["outside"] } as unknown as Claims;
 	await expect(Key.sign(scoped, outside)).rejects.toThrow("legacy put/get");
+	const getOnly = { root: "demo", get: ["room"] } as unknown as Claims;
+	await expect(Key.sign(Key.parse(encodeJwk(testKey)), getOnly)).rejects.toThrow("legacy put/get");
