Platform API mints an outbound token carrying roles=["platform-api-system"] when it calls the portal's admin REST to publish APIs, MCP servers, their content, and subscription plans. In role-authorization mode (the default), the portal looks that role up in this file and expands to the corresponding dp:* scopes. Without an entry the token authenticates but the request is denied for lack of scopes. The role is added as a distinct entry rather than a dp_admin alias: it's a service identity (not a human persona) and its grant is a strict subset of dp_admin's — publishing scopes only, no access to organization settings, applications, subscriptions, webhooks, or key managers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The passport-oauth2 callback used safeDecodeJwt on the id_token and
access_token freshly returned by the IDP. safeDecodeJwt reads the
payload without any signature, issuer, audience, or expiry checks — so
a tampered token or one issued for a different audience by the same
IDP would still be accepted as the login identity.
Replace with a verifyIdpJwt helper that uses jose's jwtVerify against
the same JWKS URL the OAuth strategy is already configured with:
- id_token audience defaults to auth.idp.clientId (OIDC Core §3.1.3.7).
- access_token audience uses auth.idp.audience when configured;
otherwise aud validation is skipped for the access token while
signature / issuer / expiry checks still run.
- Verification failure surfaces as a login failure (done(err)) rather
than a silently-accepted forged token.

Two assertions hard-coded the shipped role-to-scope-mapping.yaml's role count. Adding platform-api-system flips 4 → 5 in both places.
Covers verifyPlatformJwtClaims (signature match, wrong-key rejection, expired-token rejection, malformed input, missing key file, empty-scope handling) and decodePlatformJwtClaims (parses without verifying, returns null for malformed input). Uses node:test and jose helpers to build tokens rather than relying on external fixtures.

Pull request overview
This PR updates the API Portal to (1) introduce a narrow service role for Platform API outbound publishing, and (2) ensure the OAuth2 login callback verifies IDP tokens using the configured JWKS (aligning login-time validation with existing bearer-token validation).
Changes:
- Added
platform-api-systemrole to the shipped role-to-scope mapping with only thedp:*:managescopes needed for outbound publish artifacts. - Replaced non-verifying JWT decode in the
passport-oauth2verify callback withjose.jwtVerifyagainst the configured IDP JWKS (with issuer/audience enforcement as configured). - Updated config/role-mapping tests for the new role and added unit tests for existing Platform JWT verify/decode helpers.

…ope test
Five follow-ups from CodeRabbit + Copilot review of the previous commits:
1. Cache JWKS resolver at module scope, keyed by URL. createRemoteJWKSet
keeps an internal key cache and rate-limits refreshes; recreating it
on every verifyIdpJwt call (twice per login) threw that state away
and pushed the JWKS endpoint on every login.
2. Fail closed in verifyIdpJwt when the token argument is falsy. The
helper previously returned {} on a missing token, which let the
OAuth2 callback continue with empty claims and land the user in a
session that 403'd on every subsequent request. The docstring already
said "throws when checks fail" — this makes the code match.
3. Return a generic error to Passport (Login failed: token verification
error) and keep the underlying jose message in the log. Depending on
how the callback route renders the error, the raw message could leak
JWKS URL parse failures, network errors, etc. to the browser.
4. Require auth.idp.jwks_url in configLoader when auth.mode = "idp".
Both the login callback (passportConfig.js) and the REST bearer
verifier (authMiddleware.js) already require it at request time;
fail closed at startup instead of at first login.
5. Assert the shipped platform-api-system role's exact scope list in
roleScopeMap.test.js (in addition to the role-name-only assertion).
Pins the least-privilege contract so a silent scope widening or
narrowing fails this test.

Purpose
Two changes on the API Portal that support Platform API's outbound publish path and align existing IDP-login handling with the JWKS URL the deployment is already configured with.
dp_adminwould grant it far more than it needs (organization settings, applications, subscriptions, webhooks, key managers). A narrower service role scoped to just the artifacts Platform API produces keeps the grant surface small.safeDecodeJwton the id_token and access_token — a plain base64 decode, no JWKS verification. The rest of the auth stack (authMiddleware.js,tokenUtil.js) already verifies bearer tokens againstconfig.auth.idp.jwksUrl. This PR wires the login callback to that same URL so signature / iss / aud / exp checks apply at login too.Goals
platform-api-systemrole inrole-to-scope-mapping.yamlwith the fivedp:*:managescopes Platform API needs to publish content into the portal.safeDecodeJwtin the passport-oauth2 verify callback withjose.jwtVerifyagainst the JWKS URL already configured for the IDP.4 rolesto5 roles, and add unit tests for the pre-existingplatformJwtverify/decode helpers.Approach

Usesjose.createRemoteJWKSet(new URL(config.auth.idp.jwksUrl))andjose.jwtVerifywithalgorithms: constants.JWT_ASYMMETRIC_ALGORITHMS, plusissuerwhen configured. Audience is passed per token type by the caller.id_token→verifyIdpJwt(params.id_token, config.auth.idp?.clientId)— audience is the client_id per OIDC Core §3.1.3.7.access_token→verifyIdpJwt(accessToken, config.auth.idp?.audience)— audience usesauth.idp.audiencewhen configured; skipped otherwise sinceaudon access tokens varies by IDP. Signature / iss / exp still run.done(err)— the callback no longer falls through with empty claims when a token fails to decode.Tests:
