The backend needs each subject's roles and the names of roles and permissions for a new e-signing feature (which roles or permissions may use each drive). The snapshot only carried permissions.

Additive to polinetwork.access-snapshot/v1, so the rollout order with the backend and @polinetwork/auth-kit does not matter:

• subjects[].roles: Record<roleKey, { validUntil: string | null }>, the effective roles. These are the roles granted by any path (manual assignment, IDP_ADMIN_USER_IDS, student proof, Entra groups) plus every role they inherit through parents, using the same expansion as permission resolution (resolveAccess). Each role carries the latest expiry among its paths, merged like permissions, and expired paths are omitted. Sorted by key. Which subjects are included does not change.
• catalog: { roles: { key, name }[]; permissions: { key, name }[] }. It lists every role in the RBAC catalog and every permission the projection carries (the IdP-managed idp:* ones are excluded), sorted by key.
• The catalog is part of the fingerprint, so renaming a role or permission bumps generation and the ETag.

Changes:

• src/auth/access-snapshot.ts: projectBackendSubjects collects roles next to permissions; new projectBackendCatalog; AccessSubject/AccessSnapshot types
• tests: inherited roles through parents, expiry merge across paths, expired paths dropped, legacy Master Admin parent edges ignored, catalog filtering and naming; integration expectation updated
• RFC v3 §5.3 and README updated

vp check still reports the pre-existing formatting issue in src/dev/personas.ts, which this PR leaves alone. The Postgres/HTTP integration tests did not run locally.

Walkthrough

The access snapshot now includes effective roles with expiry data and a catalog of role and backend permission names. Snapshot fingerprinting includes the catalog. Tests and documentation cover the updated response.

Changes

Access snapshot projection

Layer / File(s)	Summary
Effective role projection src/auth/access-snapshot.ts, src/auth/access-snapshot.test.ts	Subject projection resolves inherited roles and permissions. It records the latest validity across granting paths, emits role expiry data, and retains the existing omission of subjects without permissions.
Catalog and snapshot output src/auth/access-snapshot.ts, src/auth/access-snapshot.integration.test.ts, src/auth/access-snapshot.test.ts, README.md, docs/idp-telegram-integration-rfc-v3.md	The snapshot includes a sorted catalog of roles and non-managed permissions, and its fingerprint includes the catalog. Tests and documentation cover the catalog, role maps, and role expiry rules.

Priority: ⬇️ Low

Change: Feature

Merge Risk: 🔵 Low · up to 57194

The snapshot could expose a custom idp:* permission to backend consumers, which contradicts the projection contract. This is a small, localized fix to make before or soon after merge.

- Line 150: Update the permission filters in the access snapshot projection to
exclude every key beginning with the idp: namespace, both in catalog.permissions
and resolved.permissions, rather than relying on exact managed-key matches.
Remove the isManagedPermissionKey import if it is no longer used.
