Security follow-ups (audit 2026-05-30, both reviewed APPROVE):
- MEDIUM: viewer tokens were never blacklisted on logout, so a minted
session-scoped viewer token stayed valid up to its 5-min TTL after the user
logged out. Add a per-user ViewerTokenRegistry (Arc<Mutex<HashMap<sub,
Vec<(token, expires_at)>>>>, prune-on-insert) on AppState; mint_viewer_token
registers each token under the user sub; logout drains take_for_user(sub) and
blacklists each via the existing token_blacklist. The viewer WS already calls
is_revoked, so no WS change. Key chain user.user_id == ViewerClaims.sub ==
registry key verified consistent. 8 new tests.
- LOW: relay chat logs now emit content length, not the chat body (support-chat
can carry secrets/PII).
cargo fmt/clippy(-D warnings)/test green on GURU-5070 (37 agent + 61 server).
