fix(auth): read and write legacy put/get token grants - #4190
Conversation
moq-auth and @moq/auth refused every token and scoped JWK minted by the published moq-token format, and old verifiers read new tokens as granting nothing. Legacy put/get prefixes now read as subtree patterns, and grants that are all subtrees are written that way, so issuers and verifiers can upgrade in either order.

When Key.sign is called from JavaScript or with an untyped object such as { root: "demo", put: ["outside"] }, the newly accepting schema validates and transforms it, but that return value is discarded. ensureClaimsWithinScope therefore sees no publish grant and allows it, while encodeGrants preserves the original put field and signs the out-of-scope capability. Use the parsed ClaimsSchema output for both the scope check and encoding so legacy-shaped input cannot bypass a scoped key.

For deployments already running the pattern-only moq-auth 0.1.0/0.1.1 or @moq/auth through 0.2.0, upgrading the issuer first makes subtree tokens use put/get, which those remaining verifiers explicitly reject. Thus these versions cannot upgrade in either order, and following this guidance can invalidate every newly minted subtree token until the verifiers are upgraded; document verifier-first or lockstep sequencing instead.

In the Rust wire decoder, wrapping grant fields in Option makes serde treat an explicit JSON null as if the field were absent. Consequently Rust accepts payloads such as {"put":null,"publish":["foo"]} or {"publish":null,"subscribe":["foo"]}, while the corresponding JavaScript schemas reject them; the former also bypasses the new mixed-encoding check. A token from a custom issuer can therefore be accepted by Rust verifiers but rejected by JavaScript verifiers, so the decoder should preserve field presence and explicitly reject null grants.

When a legacy token uses an empty root and a valid 32-segment put or get prefix, Pattern.subtree appends **, producing 33 segments and throwing because patterns are limited to 32. The transform consequently rejects a previously valid credential in both implementations, even though at maximum path depth the prefix is equivalent to the 32-segment literal because no deeper valid path exists. Decode this boundary case as a literal, and consider the equivalent reverse encoding, to preserve published-wire compatibility. (Written by GPT-5.6 Sol)

Declining: a legacy prefix at the full 32-segment depth is refused loudly rather than misread, which matches the fail-closed rule. Decoding it as a literal would add a depth special case to both languages' encoders for credentials that are unlikely to exist. Happy to revisit if one shows up.

Problem
The release that moved tokens to patterns (#3684) broke every published credential in both directions:
moq auth serve, refuses everyput/gettoken its existingmoq-token/@moq/tokenissuer mints.moq-auth/@moq/authreads as granting nothing to any older verifier.moq-dev/smoke#49 reproduces the break against
moq-token-cli0.5.38.Approach
put/getand read each prefixpas the subtreep/**(""reads as**), viaPattern::subtree. A document that mixes the two encodings is refused. A legacy prefix containing*is refused, since reading it would silently widen the grant.p/**or**, it is written asput/get, so every published verifier agrees on what it grants. Anything else (an exactfoo, or*/chat) is written aspublish/subscribe, which an older verifier refuses rather than misreads.try_from/intothrough a privatewiremodule. JS decodes in the zod schemas and encodes inKey.signand the CLI key writer, using a privatewire.ts.Impact
put/getencoding. Subtree-only grants are emitted in that form. Grant semantics are unchanged.Claims,Scope,ClaimsSchema, andScopeSchemakeep their shapes. The JS schemas now accept and translateput/geton input.moq-auth0.1.0/0.1.1 and@moq/auth≤0.2.0 refuse legacy-encoded tokens, so an issuer upgraded to this release needs verifiers on this release too. Follow-up after publishing: yank and deprecate those versions.Alternatives
