Classic read-then-write pattern prevents interleaved forced reflows. + +### 2.2 Clean up ResizeObservers — Already implemented +- `forceCloseSubagentWindow()` disconnects observers (app.js:12618-12620) +- `cleanupAllFloatingWindows()` disconnects all on reconnect (app.js:12649-12653) +- Observer refs stored on `windowData.resizeObserver` (app.js:12492) + +### 2.3 Drag handler cleanup — Already implemented +- `makeWindowDraggable()` returns listener refs, stored in `windowData.dragListeners` +- `forceCloseSubagentWindow()` removes all document-level drag listeners (app.js:12622-12630) +- Panel drags add listeners on mousedown, remove on mouseup (app.js:10253-10284) + +### 2.4 Mobile window position cache — Skipped +- O(n) loop over max ~20 windows; complexity of cached counter not justified + +### 2.5 Lazy modal DOM — Skipped +- Large effort, marginal benefit for a vanilla JS app with fast DOM construction + +--- + +## Phase 3: Backend Hot Paths + +### 3.1 State diff broadcasts — ALREADY OPTIMIZED +- `broadcastSessionStateDebounced()` already batches at 500ms intervals +- `toLightDetailedState()` excludes heavy buffers (textOutput, terminalBuffer) +- Per-session serialization is <1ms; with debouncing, only 1-3 sessions serialize per flush +- JSON.stringify happens once per broadcast (not per client) — serialization cost is negligible +- Full state diffs would add significant frontend complexity for marginal gain + +### 3.2 Improve session list cache hit rate — DONE +- **Files**: `src/web/server.ts` (`broadcast()` method) +- **Change**: Cache now only invalidated on truly structural events (`session:created`, `session:deleted`, `session:updated`) instead of on every `session:*` and `respawn:*` event. High-frequency events like `session:working`, `session:idle`, `session:completion`, `respawn:stateChanged` no longer defeat the 1s TTL cache. +- **Impact**: Cache hit ratio from ~0% to ~80%+ during active sessions. The debounced `session:updated` still refreshes the cache within 500ms of any state change. + +### 3.3 Skip PTY processing — ALREADY OPTIMIZED +- `_processExpensiveParsers()` is already throttled to every 150ms (not per-chunk) +- Lazy ANSI stripping via `getCleanData()` closure — only computed when a consumer needs it +- Quick pre-checks skip parsers when content is irrelevant (e.g., token parser only runs if data contains "token") +- OpenCode sessions skip all Claude-specific parsers entirely +- Further optimization would require visibility-aware processing, adding complexity for marginal gain + +### 3.4 Batch subagent liveness checks — Deferred +- `/proc/{pid}` stat calls are ~0.1ms each; even with 500 agents, total is 50ms every 10s +- Current approach is simple and reliable; batching adds race condition risk +- Consider only if profiling shows this as a bottleneck + +### 3.5 Deduplicate detection update emissions — DONE +- **Files**: `src/respawn-controller.ts` (`startDetectionUpdates()`) +- **Change**: Detection status now only emitted when key fields (confidenceLevel, statusText, controller state) actually change. Previously emitted every 2s regardless, broadcasting identical status to all SSE clients. +- **Impact**: For stable/idle sessions, eliminates ~100% of redundant detection broadcasts. For active sessions, reduces broadcasts to only meaningful state transitions. + +--- + +## Phase 4: System-Level Improvements + +### 4.1 Incremental state persistence +- **Files**: `src/state-store.ts` (~lines 145-160) +- **Problem**: Every 500ms debounce writes the entire `AppState` (all sessions, tasks, config) via `JSON.stringify()`. With 50 sessions, state can be tens of MB. Serialization alone costs 50-100ms. +- **Fix**: Track dirty sessions. On persist, only re-serialize dirty sessions; cache serialized JSON for clean sessions. Assemble final output from cached fragments. +- **Impact**: Reduces serialization cost from O(all sessions) to O(dirty sessions). Typical steady-state: 1-2 dirty sessions instead of 50. + +### 4.2 Replace polling with fs watchers for team watcher +- **Files**: `src/team-watcher.ts` (~lines 148-180) +- **Problem**: Polls `~/.claude/teams/` every 5s via `readdir()` + `stat()`. Blocks event loop for 100-200ms on large directories. +- **Fix**: Use `chokidar` (already a dependency) or `fs.watch()` to react to changes. Keep a 30s fallback poll for reliability. +- **Impact**: Eliminates 5s polling overhead; near-instant team detection. + +### 4.3 Consolidate subagent file watchers +- **Files**: `src/subagent-watcher.ts` (~line 229+) +- **Problem**: One chokidar watcher per agent directory. With 500 agents, that's 500 inotify watchers consuming kernel resources. +- **Fix**: Watch at the session level (one watcher per session's subagent directory), not per-agent. Parse events to route to correct agent. +- **Impact**: Reduces inotify watchers from 500 to ~50 (one per session). + +### 4.4 Stream transcript files instead of full reads +- **Files**: `src/subagent-watcher.ts` (~lines 959-964) +- **Problem**: `loadTranscript()` reads entire transcript file (can be >100KB). With 500 agents discovered at once, that's 50MB of file reads. +- **Fix**: Only read last 10KB for display (tail). Full file on-demand only (e.g., when user opens transcript viewer). +- **Impact**: Reduces file I/O from 50MB to 5MB for bulk agent discovery. + +--- + +## Phase 5: Long-Term Architectural (Optional) + +### 5.1 Worker thread for PTY processing +- **Files**: `src/session.ts` +- **Problem**: ANSI stripping, Ralph tracking, and bash tool parsing all run on the main event loop. At scale (50 busy sessions), this consumes 300-500ms CPU/sec. +- **Fix**: Offload ANSI strip + line processing to a worker thread pool. Main thread receives clean text + parsed events. +- **Impact**: Frees event loop for I/O operations. Most impactful at 10+ concurrent busy sessions. + +### 5.2 Per-session SSE subscriptions +- **Files**: `src/web/server.ts` +- **Problem**: Every SSE event is broadcast to all connected clients. A client watching session A still receives events for sessions B through Z. +- **Fix**: Clients subscribe to specific session IDs. Server only sends events to interested clients. +- **Impact**: Reduces SSE broadcast fan-out from N clients to ~1-2 per event. Major improvement at 100 SSE clients. + +### 5.3 O(1) LRUMap via doubly-linked list +- **Files**: `src/utils/lru-map.ts` (~lines 98-110) +- **Problem**: `get()` uses delete + re-insert to refresh position — O(n) on Map iteration for delete. +- **Fix**: Implement classic LRU with doubly-linked list + Map for O(1) get/put/evict. +- **Impact**: Low — current sizes (max 500) make this barely measurable. Only worthwhile if LRUMap is used on hot paths. + +--- + +## Priority Matrix (Remaining Work) + +| # | Item | Impact | Risk | Effort | +|---|------|--------|------|--------| +| 3.1 | State diff broadcasts | **Very High** | Medium | 3-4h | +| 3.2 | Fix session cache invalidation | **High** | Low | 1h | +| 3.3 | Skip PTY processing for hidden sessions | **High** | Medium | 2-3h | +| 3.5 | Throttle detection broadcasts | **Medium** | Low | 1h | +| 3.4 | Batch liveness checks | **Medium** | Low | 1-2h | +| 4.1 | Incremental state persistence | **Medium** | Medium | 3-4h | +| 4.2 | Team watcher fs events | **Low-Med** | Medium | 2h | +| 4.3 | Consolidate file watchers | **Low-Med** | Medium | 2h | +| 4.4 | Stream transcripts | **Low-Med** | Low | 1h | +| 5.1 | Worker thread PTY | **Med** (at scale) | High | 8h | +| 5.2 | Per-session SSE subs | **Med** (at scale) | High | 4h | +| 5.3 | O(1) LRUMap | **Very Low** | Medium | 2h | + +--- + +## Recommended Execution Order + +**Sprint 1** (Phase 3 — Backend Hot Paths): Items 3.1, 3.2, 3.3, 3.5 +- Backend serialization and broadcast efficiency +- Highest remaining impact; requires careful testing with multiple active sessions + +**Sprint 2** (Phase 4 — System Level): Items 4.1, 3.4, 4.3, 4.4 +- State persistence, liveness checks, watcher consolidation +- Medium-complexity refactors + +**Sprint 3** (Phase 5 — Architectural): Items 5.1, 5.2 — only if scaling demands it + +--- + +## Measurement + +Before starting implementation, establish baselines: + +1. **Frontend**: Record Chrome DevTools Performance trace with 10 sessions open.
