Randall Stillwell 336a5890a8 feat(audit): append-only audit_log, workspace archive cascade + restore, audit view
Soft-delete cascade was the missing half of archive: stamping
workspaces.archived_at alone left objects visible to anyone with a
direct id. The cascade runs in one transaction so the partial state
isn't reachable, and restore inverts it for any archived row in the
workspace — provenance-blind on purpose until we have a use case
that needs to distinguish per-workspace from per-object archives.

audit_log keeps the keyset index on (workspace_id, created_at) and
the actor_user_id FK with onDelete set null. recordAudit() refuses
to write a null actor without a metadata.system_actor label so the
audit view always has something to render. workspaces and invites
mutations call recordAudit on success; objects-router instrumentation
and the markdown importer's system-actor flow are filed as P2
follow-ups because each needs a thoughtful "what's audit-worthy?"
pass, not mechanical wiring.

Settings → Audit log lives at /<slug>/settings/audit, owner-gated,
keyset-paginated. ACTION_LABELS is small on purpose; new actions
fall back to their raw key so missing a label degrades gracefully.

Task summary

The parent task (Task-rate-limit-and-abuse-guardrails) shipped rate-limits on Credentials sign-in and invite-create. Two more endpoints from the original spec are still wide open:

  • workspaces.create — a malicious or buggy script could create thousands of workspaces under one user. Suggested limit: 5 / actor_user_id / hour.
  • workspaces.archive / workspaces.restore — flipping state in a loop is cheap. Suggested limit: 20 / (workspace_id, actor_user_id) / hour.

Use the same rateLimit() primitive at apps/web/server/lib/rate-limit.ts.

Subtasks

  • Add the limiter call to workspaces.create (top of mutation, after protectedProcedure's auth check).
  • Add the limiter call to workspaces.archive and workspaces.restore.
  • Verify by smoke-test: 6 rapid workspace creates → 5 succeed, 6th returns TOO_MANY_REQUESTS.

Acceptance criteria

  • Workspace-create trip fires at attempt 6 within an hour.
  • Archive/restore trip fires at attempt 21 within an hour for the same (workspace_id, actor_user_id) pair.
