Measured on a copy of a real 1.2 GB / 253K-event database, 10 simulated browsers + 10 hooks/s for 90 s: event-loop delay p99 1239 ms → 32 ms (max 2.0 s → 94 ms), 266 failed requests → 0, 74 → 111 requests/s served, server RSS 633 → 346 MB. Entry bundle 975 KB raw → 394 KB (106 KB brotli). Server - /api/analytics: the events-table scans run in the read worker (scoped-stats eventAggregates, read-pool job analyticsEvents); runRead takes maxAgeMs — analytics 10 s, /api/workflows 30 s — keyed by the args - /api/workflows/skill-usage: +event_type and a tool_name range instead of LIKE, so it uses idx_events_tool (784 ms → a few ms) - idx_events_session_type_tool (session_id, event_type, tool_name, created_at) replaces idx_events_session_type: covering reads for session stats, the hook dedupes and the import resume point (1.2 s → 20 ms); 64 MB cache_size and 256 MB mmap_size on both connections - WAL: the server sets wal_autocheckpoint = 0 and checkpoints PASSIVE every DASHBOARD_WAL_CHECKPOINT_MS (5 s) from the read worker's own writable connection; a failed checkpoint restores the automatic one (hook COMMIT p95 109 ms → 15 ms at 100 hooks/s) - tmux: one list-sessions answers a whole GET /api/lanes and the heal beat (liveSessions), shared for 1 s and cleared by this process's new/kill — GET /api/run's sync spawns had blocked 60 s of a 90 s run; the heal beat skips tmux when nothing runs; attach options chained into 2 spawns - hooks: TurnDuration/APIError deduped against one read per hook instead of a query per transcript entry (23 ms/hook on a 763-turn session); one lane scan per hook; hourly upserts skip rows that did not grow; frames are sent after the transaction commits (and after the pane binding); new_event carries its row id; a split pane's (slot 1–9) hooks no longer rebind the lane's session_id - watchdog liveness probe runs ps asynchronously; transcript newline scan via indexOf; startup subagent backfill fingerprints the files it already checked - pty attach: backpressure (pause past 1 MB unsent, resume under 256 KB) - static: hashed assets served from their pre-compressed .br/.gz sibling Client - hidden tabs neither refetch on WS events nor poll (useLiveRefresh, panes, lane cards, git header, changes panel, settings); no per-tab hourly /updates/check (the server already checks) - refetch storms throttled (workspace tree/session list 3 s, /api/run only on a run-key change, notification pane lookup only when shown); WS reconnect jitter; terminal retry backoff 1.5 → 30 s, stops on 1008 - heavier throttles for aggregates (15 s) and detail views; Monitor keepIfSame; GET in-flight dedupe in request() - lazy Dashboard/History, xterm (with the first terminal), lane modals, Sagi (only while enabled); only the active locale loads; Workspace chunk prefetched on a /workspace deep link - Sagi: no work while disabled, pupil via CSS variables, memo avatar - build: .br/.gz siblings, sourcemap hidden; service worker no longer caches /assets/ (cache v3 drops the old one) Tests: scripts/test-server.js drops the GIT_DIR-family variables a hook exports, so a suite run from a linked worktree's pre-commit can no longer commit into the real repository or set core.bare.

/**

* @file laneChange.ts
|
|
* @description `lane_update` matcher for live-refresh callers that care about
|
|
* only a few lane columns. A lane is re-broadcast on every hook (last event,
|
|
* liveness…), so matching the bare message type made every such frame refetch;
|
|
* this one fires only when the chosen key of a lane actually changed, or when a
|
|
* lane was removed. Each call keeps its own memory of the keys it has seen.
