* feat(auth): cache workspace membership for daemon heartbeat path Cache workspace membership existence (not role) in Redis to eliminate a DB round-trip on every PAT-authenticated daemon heartbeat. Follows the existing PATCache nil-safe pattern. Key design decisions per reviewer feedback: - Cache existence only (sentinel "1"), not role string. Authorization decisions that depend on role always hit the DB directly. This eliminates the cache-aside race where a stale elevated role could persist after a downgrade. - Proactive invalidation on UpdateMember, DeleteMember, LeaveWorkspace, and DeleteWorkspace (iterates members before cascade delete). - 5 min TTL. Combined with PATCache (10 min), worst-case revocation delay is max(10m, 5m) = 10 min — consistent with original PATCache design decision. Limitations: - Non-members still hit DB on every request (negative caching not implemented — the scenario is rare for daemon endpoints which require valid workspace-scoped tokens). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: multica-agent <github@multica.ai> * test(auth): drive membership cache invalidation through real handlers - TestRequireDaemonWorkspaceAccess_CacheHit now uses a ghost user with no member row, so the only path to a granted access is the cache short-circuit. Without priming the cache the access check must fail; with priming it must succeed. A future change that bypasses the cache would fail the second assertion. - Replaces the cache-only InvalidatedOnMemberRemoval test (which only re-exercised the auth-package primitive) with four handler-driven tests that exercise DeleteMember, UpdateMember, LeaveWorkspace and DeleteWorkspace via their real HTTP handlers. Each test prepares a real member, primes the cache, calls the handler, and asserts the cache entry is gone — so a refactor that drops one of the Invalidate(...) calls in workspace.go will fail CI.
