security-auditor	c0f4c16cc9	feat(canvas): ActivityTab subscribes to ACTIVITY_LOGGED — drop 5s polling ... Stage 3 of #61 (final stage). Replaces the 5s setInterval poll with: 1. Initial bootstrap on mount + on filter-change + on workspaceId- change (preserved from existing useEffect on loadActivities). 2. Manual Refresh button (preserved — still triggers loadActivities). 3. useSocketEvent subscription to ACTIVITY_LOGGED — every event for THIS workspace prepends to the list, gated on the user's autoRefresh toggle and current filter selection. No interval poll. Steady-state HTTP traffic from this tab drops from 12 req/min (5s × 1 active workspace) to 0 outside of bootstraps and manual refreshes. Live update latency drops from up to 5s to ~10ms. The autoRefresh ("Live" / "Paused") toggle now gates LIVE updates instead of polling cadence — semantically the same (paused = list stays frozen), implementationally simpler. The filter selection is honoured by the WS handler so a user filtering to "Tasks" doesn't see live a2a_send rows trickle in. Same shape the server-side `?type=<filter>` enforces on the bootstrap. Test changes: - 27 existing tests pass unchanged (filter / autoRefresh / Refresh / loading / error / empty / count / row-content all preserved) - 7 new WS-subscription tests: - WS push for matching workspace prepends with NO HTTP call - WS push for different workspace ignored - WS push respects active filter (non-matching ignored) - WS push respects active filter (matching renders) - WS push while autoRefresh paused ignored - WS push for already-in-list row deduped (no double-render) - NO 5s interval polling after mount Mutation-tested: - drop workspace_id filter → "different workspace" test fails - drop autoRefresh gate → "paused" test fails - drop filter gate → "non-matching activity_type" test fails - drop dedup-by-id → "already in list deduped" test fails Full canvas suite: 1396 passing, 0 failing. tsc clean. No API or schema change. /workspaces/:id/activity HTTP endpoint stays — used for bootstrap + manual refresh + filter-change reload. ACTIVITY_LOGGED event shape unchanged. Hostile self-review (three weakest spots): 1. Server-side activity_logs row UPDATES (status flips, etc.) are not reflected post-#61 — the dedup-by-id check skips a re-fired ACTIVITY_LOGGED for an existing row. Acceptable: activity_logs is append-only by design (audit trail); status updates surface as new task_update rows, not as in-place mutations. If a future server change adds in-place updates, fire ACTIVITY_UPDATED as a distinct event so this dedup logic stays simple. 2. WS handler is recreated on every render (filter / autoRefresh / workspaceId state changes). useSocketEvent's ref-based pattern keeps the bus subscription stable, but the handler closure re-captures each render. Side effect: fine — handler call cost is negligible. 3. The "error" filter matches activity_type === "error" (mirrors server semantics). It does NOT match status === "error" rows of other activity types — same as the polling version. Worth re-evaluating in a separate PR if users expect the broader semantic.
