Summary

This implements the adopter-token auth mode from ADR-056 §2, which until now was a stub that returned 501. Frigg can now verify tokens issued by an adopter's own identity provider directly, so a caller needs no shared secret and no relay. The first consumer is Left Hook's internal MCP server: admin.lefthook.com issues ES256 tokens, and frigg-internal verifies them against admin's JWKS. See lefthook.com ADR-0016 D6 and the build plan in lefthook.com PR #758.

This PR is stacked on #671 (feat/management-api-v2). Canaries are published from this branch for development use until it merges down.

What it does

• user/adopter-token-verifier.js is a new adapter that owns the config, the JWKS and the mapping from failures to reason codes. It is built once per router or dependency set, not once per request.
  • Algorithms come from an allow-list. Defaults are ES256/RS256 with jwksUri, and HS256 with secret. The jku/jwk headers are never followed.
  • exp is required. iss and aud are checked, and clockTolerance is bounded.
  • Only known token failures return 401. Anything else, including connection refused, a DNS failure, a timeout or a bad JWKS body, returns 503 jwks_unavailable, so a key-server outage does not log users out.
• GetUserFromAdopterJwt takes the user from userIdClaim (default sub) and the active org from orgIdClaim, and exposes the role through User#getOrgRole().
  • A person is never silently re-linked. If an individual already belongs to org A and the token names org B, the request gets a 403 multi_org_unsupported. This check runs before anything is created. It is interim until OrganizationMembership lands in F4 (ADR-056 §3.6).
• Config is validated at app-definition load (adopter-jwt-config.js):
  • Exactly one of secret or jwksUri may be set.
  • HS* algorithms are only allowed with a secret, and asymmetric ones only with a JWKS.
  • jwksUri must be https; http is allowed only to loopback.
  • audience is required when jwksUri is set, and a warning is logged when issuer is unset.
  • The JSON schema mirrors these rules with oneOf, a dependencies rule and a not rule.
• Shared code. user/app-user-helpers.js holds the find-or-create and buildUser logic that both this path and GetUserFromXFriggHeaders use. Each keeps its own linking policy.
• Typings. types/user/index.d.ts adds UserConfig, AdopterJwtConfig and User#getOrgRole/setOrgRole.
• Dependency. jose@^5.10.0.

Known, not fixed here

• GetUserFromXFriggHeaders compares individual.organizationUser, but the repositories return organizationId, so its mismatch check is always true. That will be tracked separately.
• Two concurrent first logins can race on create or link, and the first org link is one-way. Both are documented in code; F4 replaces this path.

Test plan

• Adopter suites: 97 tests across 5 files. One of them is the remote-JWKS suite, which runs a real local JWKS server and covers caching, an upstream 500, a closed port, an unresolvable host and a hang.
• Full packages/core run, with the no-op global setup because Mongo binaries can't run in CI-less containers: 15 suites and 63 tests fail. The failing tests match base by name, minus the 2 from the deleted stub suite. 2931 pass.
• packages/schemas: 154 pass.
• ESLint on changed files: 0 errors.
• Two independent reviews (spec/test and clean code). The implementer killed 64 mutations across two rounds. Reviewers ran 30 more against the first round: 28 killed, and the 2 survivors now have tests. Live jose probes were rejected: alg: none, HS256 signed with the public key, forged jku and jwk headers, issuer mismatch.

ADR reconciliation needed after Stack A/B — drafted with Claude Code at Sean's request

Severity: must-reconcile (text only; the code looks consistent with the intent of ADR-056 §2).

• ADR-056 §2 config names. §2 (in docs(adr): ADR-056 app profiles, tenancy and entity scopes #670/docs(adr): ADR-056 §3.1–3.6 ownership overrides + multi-org membership; ADR-059 app-level entity registry #677) specifies user.jwt.claims: { userId: 'sub', orgId: 'org_id', role: 'org_role' }. This PR ships user.jwtConfig with userIdClaim/orgIdClaim/roleClaim (same defaults), jwksUri xor secret, issuer, audience (required with JWKS), algorithms, clockToleranceSec. Either is fine, but the ADR and the code must agree. Since the schema and typings already use jwtConfig, the edit belongs in 056 §2 (asked on docs(adr): ADR-056 §3.1–3.6 ownership overrides + multi-org membership; ADR-059 app-level entity registry #677).
• ADR-034 (API-key login, docs(adr): reconcile the register — 13 unmerged ADRs into one contiguous sequence #644/feat(core): API-key login auth mode (module-validated) #643). 034's Context says browser apps are forced into a BFF. With adopter JWT, that is true only for products without an IdP. Please ask docs(adr): reconcile the register — 13 unmerged ADRs into one contiguous sequence #644 to:
  1. Reposition 034 as "products whose API key is the identity, with no IdP of their own", and cite 056 §2 as the IdP path.
  2. Make 034's find-or-create reuse user/app-user-helpers.js from this PR and the membership path from feat(core): organization memberships, one active org per request (ADR-056 §3.6) #681 (056 §3.6), not the legacy organizationId re-link that this PR guards with 403 multi_org_unsupported.
  3. Decide the org role of a 034 session (056 §3.6 "Frigg bearer token … may manage").
• ADR-056 §2 "until then, the BFF pattern is the supported approach": once this merges, that sentence should say the BFF remains supported but is no longer required for IdP-backed products.
• ADR-051 (feat(devtools): frigg validate, and make the app-definition schema match the runtime (ADR-051) #666). user.jwtConfig.* with its oneOf/dependencies/not rules is added to the feat: Management API v2, /api/meta, v1 deprecation and the locked-down entity proxy (ADR-052, ADR-053) #671 copy of app-definition.schema.json. feat(devtools): frigg validate, and make the app-definition schema match the runtime (ADR-051) #666 rewrites that file (user.strictUserValidation, new root keys). Whichever lands second must carry both, and frigg validate should report the "both jwksUri and secret" and "HS* with JWKS" errors this loader throws.

Merge order: #671 → this PR. #644's ADR-034 edit is independent but should land before #643's code.
