 # aicodeman
 
+## 0.5.6
+
+### Patch Changes
+
+- fix: default new sessions to opus[1m] (1M context window) instead of plain opus (200k context)
+
+## 0.5.5
+
+### Patch Changes
+
+- Add 1M Opus context quick setting — per-case and global toggle that writes `model: "opus[1m]"` to `.claude/settings.local.json` when creating new sessions. Fix mobile layout: banners (respawn, timer, orchestrator) between header and main content now visible by switching from margin-top on `.main` to padding-top on `.app`. Add tablet-optimized respawn banner styles and mobile phone banner refinements.
+
+## 0.5.4
+
+### Patch Changes
+
+- Fix terminal flicker regression — re-add server-side DEC 2026 synchronized output wrapping around batched terminal data. Ink spinner frames (cursor-up + redraw cycles) do not emit their own DEC 2026 markers, so without the server wrapper each partial cursor update rendered individually causing visible flicker. Also: extract SSE stream management, session listener wiring, and respawn event wiring from server.ts into dedicated modules; deduplicate error message extraction across 7 files with shared getErrorMessage() helper; update SSE event count in CLAUDE.md (106 → 117).
+
+## 0.5.3
+
+### Patch Changes
+
+- Readability refactor across 12 core files, extracting ~35 helper methods to reduce duplication:
+  - state-store: extract serializeState(), split assembleStateJson() into focused sub-methods
+  - session: extract \_resetBuffers() (3x dedup), \_clearAllTimers() (10 timer cleanups), \_handleJsonMessage()
+  - ralph-tracker: extract completeAllTodos() (4x dedup), emitValidationWarning(), named similarity constants
+  - subagent-watcher: extract markSubagentAsCompleted(), extractFirstTextContent(), emitToolResult(), findOldestInactiveAgent()
+  - respawn-controller: extract recoveryResetToWatching(), canAutoAccept(), formatRemainingSeconds(), validatePositiveTimeout()
+  - tmux-manager: replace 15 path.includes() with UNSAFE_PATH_CHARS regex, extract buildEnvExports/buildPathExport/\_configureOpenCode helpers
+  - session-auto-ops: extract executeWhenIdle() shared retry helper, convert to options object, add validateThreshold()
+  - app.js: add \_clearTimer() (11 call sites), \_isStaleSelect(), keyboard shortcut lookup table, \_cleanupPreviousSession(), \_resetAllAppState()
+  - route-helpers: add readJsonConfig() (5 inline patterns replaced), validateSessionFilePath() (2 duplicated blocks replaced)
+
+## 0.5.2
+
+### Patch Changes
+
+- Make buffer size limits configurable via CODEMAN\_\* environment variables (MAX_TERMINAL_BUFFER, TRIM_TERMINAL_TO, MAX_TEXT_OUTPUT, TRIM_TEXT_TO, MAX_MESSAGES), falling back to existing defaults. Allows users with fewer sessions or more RAM to tune buffer sizes without patching source.
+
+  Fix duplicate terminal output on tab switch to busy sessions by clearing the terminal before writing the new buffer.
+
+  Fix stale Ink CUP frames after tab switch by sending Ctrl+L to force a clean redraw.
+
+  Fix mobile CJK input handling: resolve textarea positioning, terminal flicker during composition, and layout overflow on small screens. Improve CJK composition lifecycle with better event handling and fallback flush timers.
+
+## 0.5.1
+
+### Patch Changes
+
+- refactor: codebase cleanup — extract route helpers, eliminate boilerplate, optimize hot paths
+  - Add `parseBody()` helper to route-helpers.ts: validates request body against Zod schema with structured 400 error on failure, replacing 37 identical safeParse + error-check blocks across 10 route files
+  - Add `persistAndBroadcastSession()` helper: combines persist + SessionUpdated broadcast into one call, replacing 5 repeated 2-line pairs
+  - Migrate session-routes.ts to use `findSessionOrFail()` consistently (17 inline session lookups replaced) and `parseBody()` (12 patterns)
+  - Migrate ralph-routes.ts to use `findSessionOrFail()` (9 lookups) and `parseBody()` (4 patterns)
+  - Migrate 8 remaining route files to use `parseBody()` (21 patterns total)
+  - Fix O(n log n) eviction in bash-tool-parser.ts: replace `Array.from().sort()[0]` with O(n) min-scan for oldest active tool
+  - Extract `_debouncedCall()` utility in frontend: replaces 4 manual debounce patterns (7 lines each → 1 line) in app.js, panels-ui.js, ralph-panel.js
+  - Net reduction: 208 lines removed across 16 files
+
+## 0.5.0
+
+### Minor Changes
+
+- Visual redesign with glass morphism, refined colors, and polished UI. Optimize history endpoint with buffer reuse and line iterator. Fix Ink frame search window (4KB→64KB) to prevent partial frames. Fix stale terminal data on tab switch via chunkedTerminalWrite cancellation. Improve history prompt extraction with expanded command filtering and tail scan fallback. Align case select group height to match dropdown. Fix no-control-regex lint error for ANSI strip pattern. Add browser-testing-guide to CLAUDE.md references.
+
+## 0.4.7
+
+### Patch Changes
+
+- feat: improve session navigability in history and monitor panel (closes #45)
+  - History items now show the first user prompt as the title with the project path as a subtitle, making it much easier to distinguish sessions from the same project
+  - The `/api/history/sessions` endpoint extracts the first user message from each transcript JSONL, stripping system-injected XML tags and command artifacts, truncating to 120 chars
+  - Monitor panel session rows are now clickable — clicking navigates directly to that session's tab via `selectSession()`; Kill button retains independent behavior via `stopPropagation()`
+  - Updated CLAUDE.md architecture tables to reflect Orchestrator Loop additions (14 route modules, 15 type files, orchestrator domain files, orchestrator-panel.js frontend module)
+  - fix: stop subagent monitor windows from auto-opening on discovery
+  - feat: add Orchestrator Loop with phased plan execution, live progress during plan generation, and toolbar button (hidden until fully tested)
+  - fix: patch 3 production bugs found during deep audit
+  - fix: restore mobile terminal scrollback using JS scrollLines() instead of broken native scroll
+
+## 0.4.6
+
+### Patch Changes
+
+- Fix mobile keyboard scroll and layout issues:
+  - Prevent iOS Safari from scrolling the page when typing with the keyboard open (position:fixed on .app + window.scroll reset)
+  - Eliminate dead space between terminal and keyboard accessory bar by removing redundant CSS padding, tightening JS padding constant, and adding row quantization gap compensation
+  - Fix toolbar overlapping terminal content when keyboard is hidden by adding proper padding-bottom to .main, including iOS Safari bottom bar offset
+  - Strip Ink spinner bloat from terminal buffer before tailing
+  - Fix resolveCasePath priority order and suppress JSON parse warnings
+
+## 0.4.5
+
+### Patch Changes
+
+- Fix mobile keyboard toolbar positioning on iOS Safari: toolbar (Run/Stop/Run Shell) was hidden behind the accessory bar when virtual keyboard was active due to overlapping CSS positions. Remove the aggressive safety check in `updateLayoutForKeyboard()` that incorrectly dismissed keyboard state when iOS scrolled the visual viewport during typing. Add Safari-bar CSS offset to accessory bar so it properly stacks above the toolbar. Remove the double-counted Safari-bar offset when keyboard is visible since the JS transform already covers the full distance.
+
+## 0.4.4
+
+### Patch Changes
+
+- fix: mobile keyboard hides terminal content on iPhone
+
+  Fixed a bug where opening the virtual keyboard on iPhone left zero visible terminal space. Two independent mechanisms were both accounting for the keyboard height: `MobileDetection.updateAppHeight()` shrunk `--app-height` to the visual viewport height, while `KeyboardHandler.updateLayoutForKeyboard()` added a large `paddingBottom`. These double-counted, leaving negative space for the terminal (user saw accessory bar + toolbar but no terminal content).
+
+  Fix: `updateAppHeight()` now skips when the keyboard is visible, and `handleViewportResize()` restores `--app-height` to the pre-keyboard value on first detection (since MobileDetection's listener fires before KeyboardHandler's). On keyboard close, `--app-height` is re-synced to the current visual viewport.
+
+## 0.4.3
+
+### Patch Changes
+
+- Refactor case routes: extract readLinkedCases() and resolveCasePath() helpers to eliminate 6x duplicated linked-cases.json path construction and 5x duplicated file read/parse logic. Replace O(n) .some() duplicate check with O(1) Set.has() in case listing. Un-export unused isError() type guard. Standardize reply.status() to reply.code() in system routes. Update CLAUDE.md frontend module listing and SSE event count.
+
+## 0.4.2
+
+### Patch Changes
+
+- Extract monolithic app.js (~12.5K lines) into 6 focused domain modules that extend CodemanApp.prototype via Object.assign: terminal-ui.js (terminal setup, rendering pipeline, controls), respawn-ui.js (respawn banner, countdown, presets, run summary), ralph-panel.js (Ralph state panel, fix_plan, plan versioning), settings-ui.js (app settings, visibility, web push, tunnel/QR, help), panels-ui.js (subagent panel, teams, insights, file browser, log viewer), session-ui.js (quick start, session options, case settings). Fix critical deferred script init ordering bug: wrap CodemanApp instantiation in DOMContentLoaded so all defer'd mixin modules execute their Object.assign before the constructor runs. Guard missing cleanupWizardDragging() call in subagent-windows.js. Update build.mjs to minify/hash all new modules.

+## Integration Points with Existing Code
+
+### StateStore (`src/state-store.ts`)
+```typescript
+// Add to AppState interface
+orchestrator?: OrchestratorPersistState;
+
+// Add methods
+getOrchestratorState(): OrchestratorPersistState;
+setOrchestratorState(state: Partial<OrchestratorPersistState>): void;
+```
+
+### SSE Events (`src/web/sse-events.ts`)
+```typescript
+// Add ~8 new events
+export const SseEvent = {
+  // ... existing
+  ORCHESTRATOR_STATE_CHANGED: 'orchestrator:stateChanged',
+  ORCHESTRATOR_PLAN_READY: 'orchestrator:planReady',
+  ORCHESTRATOR_PHASE_STARTED: 'orchestrator:phaseStarted',
+  ORCHESTRATOR_PHASE_COMPLETED: 'orchestrator:phaseCompleted',
+  ORCHESTRATOR_PHASE_FAILED: 'orchestrator:phaseFailed',
+  ORCHESTRATOR_VERIFICATION: 'orchestrator:verificationResult',
+  ORCHESTRATOR_COMPLETED: 'orchestrator:completed',
+  ORCHESTRATOR_ERROR: 'orchestrator:error',
+} as const;
+```
+
+### Frontend Constants (`src/web/public/constants.js`)
+```javascript
+// Mirror SSE events
+SSE_EVENTS.ORCHESTRATOR_STATE_CHANGED = 'orchestrator:stateChanged';
+// ... etc
+```
+
+### Route Registration (`src/web/routes/index.ts`)
+```typescript
+import { registerOrchestratorRoutes } from './orchestrator-routes.js';
+// Add to barrel export
+```
+
+### Server (`src/web/server.ts`)
+```typescript
+// Initialize OrchestratorLoop alongside RalphLoop
+const orchestratorLoop = new OrchestratorLoop(config);
+
+// Register routes
+registerOrchestratorRoutes(app, { ...ctx, orchestrator: orchestratorLoop });
+```
+
+### Port Interface (`src/web/ports/`)
+```typescript
+// New port
+export interface OrchestratorPort {
+  orchestrator: OrchestratorLoop;
+}
+```
+
+## Prompt Flow Through System
+
+The key insight is how prompts flow from Orchestrator → Session → Claude:
+
+```
+OrchestratorLoop decides to execute Phase 3, Task 2
+  │
+  ▼
+Converts OrchestratorTask to CreateTaskOptions:
+  {
+    prompt: "Implement the rate limiter middleware. Read src/middleware/auth.ts
+             for the pattern. Add to src/middleware/rate-limiter.ts. Must export
+             a Fastify plugin. When done: <promise>PHASE_3_TASK_2_DONE</promise>",
+    priority: 100,
+    dependencies: ["phase-3-task-1"],  // Must finish auth middleware first
+    completionPhrase: "PHASE_3_TASK_2_DONE",
+    timeoutMs: 600000  // 10 minutes
+  }
+  │
+  ▼
+TaskQueue.addTask(options)
+  │
+  ▼
+RalphLoop.tick() → assignTasks()  // OR OrchestratorLoop does its own assignment
+  │
+  ▼
+session.sendInput(task.prompt)
+  │
+  ▼
+writeViaMux() → tmux send-keys -l "prompt..." + Enter
+  │
+  ▼
+Claude CLI receives prompt, executes, outputs results
+  │
+  ▼
+RalphTracker.processData() → detects "PHASE_3_TASK_2_DONE"
+  │
+  ▼
+emit('completionDetected') → OrchestratorLoop.handleTaskCompleted()
+  │
+  ▼
+Check: all tasks in Phase 3 done? → If yes → verifyPhase(phase3)
+```
+
+## Team Agent Flow (When Enabled)
+
+```
+Phase has teamStrategy.type === 'team'
+  │
+  ▼
+OrchestratorLoop creates/reuses a session with:
+  env: { CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS: '1' }
+  │
+  ▼
+Sends team orchestration prompt:
+  "You're the team lead for Phase 3: Core Implementation.
+
+   Your team should work on these tasks in parallel:
+   1. Rate limiter middleware (teammate 1)
+   2. Error handling middleware (teammate 2)
+   3. Validation layer (teammate 3)
+
+   Context files to read first: [...]
+   Each teammate should output their task's completion phrase when done.
+   When ALL tasks are complete, output: <promise>PHASE_3_COMPLETE</promise>"
+  │
+  ▼
+Claude Code team-lead spawns teammates
+  │
+  ▼
+TeamWatcher detects new team in ~/.claude/teams/
+  → Matches to session via leadSessionId
+  → Tracks teammate activity
+  │
+  ▼
+Teammates work in parallel (in-process threads)
+  │
+  ▼
+hook: teammate_idle → POST /api/hook-event
+  → OrchestratorLoop notes teammate finished
+  │
+  ▼
+hook: task_completed → POST /api/hook-event
+  → Or: RalphTracker detects PHASE_3_COMPLETE
+  → OrchestratorLoop → phase complete → verify
+```
+
+## Error Recovery Strategy
+
+```
+Task fails (timeout, error, session crash)
+  │
+  ├─ Task-level retry (up to 2 retries per task)
+  │   → Reset task to pending
+  │   → Re-queue with modified prompt: "Previous attempt failed: {error}. Try again..."
+  │
+  ├─ Phase-level retry (up to 3 retries per phase)
+  │   → Respawn session (fresh context)
+  │   → Re-execute entire phase with learnings from failure
+  │   → Modified prompt includes what went wrong
+  │
+  └─ Orchestration-level failure
+      → All retries exhausted
+      → state = FAILED
+      → Notify user with detailed failure report
+      → User can: modify plan → retry, skip phase → continue, or stop
+```
+
+## Interaction with Ralph Loop
+
+Ralph Loop and Orchestrator Loop are **mutually exclusive** on the same sessions:
+
+```
+if (orchestratorLoop.isRunning()) {
+  // Orchestrator controls task assignment
+  // Ralph Loop should not interfere
+  // Respawn Controller uses 'orchestrator' preset
+}
+
+if (ralphLoop.isRunning()) {
+  // Ralph controls task assignment
+  // Orchestrator should not start
+}
+```
+
+The Orchestrator can optionally USE the Ralph Loop internally for phase execution (delegate phase tasks to Ralph's queue), or manage task assignment directly. Decision: **manage directly** — gives more control over phase boundaries and verification timing.

+# Orchestrator Loop — Detailed Implementation Plan (v2)
+
+> Internal research/planning document. Not for GitHub.
+
+## Vision
+
+The **Orchestrator Loop** is a new autonomous execution mode that transforms high-level user goals into phased, verified, team-coordinated implementations. Unlike Ralph Loop (flat task queue → idle sessions), the Orchestrator manages the full lifecycle: **plan → approve → execute → verify → adapt → complete**.

+**States:** `idle` | `planning` | `approval` | `executing` | `verifying` | `replanning` | `completed` | `failed` | `paused`
+
+Transitions are event-driven. The state machine is the single source of truth — all methods check `this.state` before acting.

+
+```typescript

+
+**Phase grouping algorithm:**
+1. Topological sort by `PlanItem.dependencies`
+2. Group into dependency layers (Kahn's algorithm)
+3. Within each layer, sub-group by `tddPhase` (setup → test → impl → verify → review)
+4. Merge adjacent small phases (< 2 tasks) if they share the same tddPhase
+5. Assign team strategies:
+   - 1-2 tasks → `{ type: 'single' }`
+   - 3+ independent tasks → `{ type: 'parallel', maxSessions: Math.min(taskCount, config.maxParallelSessions) }`
+   - 4+ tasks with high complexity → `{ type: 'team', config: { ... } }`
+6. Generate unique completion phrases per task: `ORCH_P{phaseOrder}_T{taskIndex}`
+
+### Step 3: `src/orchestrator-verifier.ts` — Phase verification
+~200 lines.
+
+```typescript
+/**
+ * @fileoverview Orchestrator phase verification.
+ *
+ * Runs verification checks after each phase completes:
+ * test commands, AI review, and file existence checks.
+ *
+ * @module orchestrator-verifier
+ */

+export class OrchestratorVerifier {
+  constructor(config: OrchestratorConfig);
+
+  /** Run all verification checks for a completed phase. */
+  async verifyPhase(
+    phase: OrchestratorPhase,
+    session: Session,
+    mode: 'strict' | 'moderate' | 'lenient'
+  ): Promise<VerificationResult>;
+
+  // Verification strategies
+  private async runTestCommands(commands: string[], session: Session): Promise<VerificationCheck[]>;
+  private async aiReview(phase: OrchestratorPhase, session: Session): Promise<VerificationCheck>;
+}
+```
+
+**Verification modes:**
+- `strict`: ALL test commands must pass AND AI review must approve
+- `moderate`: Test commands must pass, AI review is advisory
+- `lenient`: At least one test command passes, AI review skipped
+
+**AI review prompt (sent as a task to the session):**
+```
+Review Phase "{phase.name}" completion. Check:
+1. Expected functionality works
+2. No obvious regressions
+3. Code quality is acceptable
+
+Criteria: {phase.verificationCriteria.join('\n')}

+}
+```
+
+**Key execution flow in `executePhase()`:**
+1. Mark phase as `executing`, emit `phaseStarted`
+2. For each task in phase:
+   - Create a `CreateTaskOptions` from `OrchestratorTask`
+   - Add to `TaskQueue` with proper dependencies + completion phrase
+   - Store the TaskQueue task ID in `OrchestratorTask.queueTaskId`
+3. Poll task completion (listen to TaskQueue events)
+4. When all tasks complete → call `onPhaseTasksComplete()`
+5. `onPhaseTasksComplete()` triggers verification
+
+**How tasks get assigned to sessions:**
+The OrchestratorLoop does NOT manage session assignment directly. It adds tasks to the existing TaskQueue and starts a mini poll loop that assigns pending tasks to idle sessions — the same pattern as RalphLoop's `assignTasks()`. This reuses existing session management.
+
+**Team agent flow:**
+For phases with `teamStrategy.type === 'team'`:
+- Start a single session with `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+- Instead of adding individual tasks to TaskQueue, send ONE comprehensive prompt to the lead
+- The prompt instructs the lead to create teammates and delegate
+- Monitor via TeamWatcher for team task completion + hook events
+- Phase completion is detected via the lead's completion phrase
+
+### Step 5: `src/web/routes/orchestrator-routes.ts` — API endpoints
+~300 lines.
+
+```
+POST   /api/orchestrator/start          — { goal, config? } → start planning
+POST   /api/orchestrator/approve        — approve generated plan
+POST   /api/orchestrator/reject         — { feedback } → reject + replan
+POST   /api/orchestrator/pause          — pause execution
+POST   /api/orchestrator/resume         — resume execution
+POST   /api/orchestrator/stop           — stop orchestration
+GET    /api/orchestrator/status         — full state + plan + stats
+GET    /api/orchestrator/plan           — plan details only
+POST   /api/orchestrator/phase/:id/skip — skip a phase
+POST   /api/orchestrator/phase/:id/retry — retry a failed phase
+```
+
+Port dependency: `SessionPort & EventPort & RespawnPort & ConfigPort & InfraPort`
+
+The route module receives the OrchestratorLoop instance via the InfraPort (added to `createRouteContext()`).
+
+### Step 6: SSE Events — `src/web/sse-events.ts` additions
+
+```typescript
+// ─── Orchestrator ────────────────────────────────────────────────────────────
+
+/** Orchestrator state machine transitioned. */
+export const OrchestratorStateChanged = 'orchestrator:stateChanged' as const;
+/** Orchestrator plan generated and ready for approval. */
+export const OrchestratorPlanReady = 'orchestrator:planReady' as const;
+/** Orchestrator phase started executing. */
+export const OrchestratorPhaseStarted = 'orchestrator:phaseStarted' as const;
+/** Orchestrator phase completed successfully. */
+export const OrchestratorPhaseCompleted = 'orchestrator:phaseCompleted' as const;
+/** Orchestrator phase failed. */
+export const OrchestratorPhaseFailed = 'orchestrator:phaseFailed' as const;
+/** Orchestrator verification result for a phase. */
+export const OrchestratorVerification = 'orchestrator:verification' as const;
+/** Orchestrator task assigned to session. */
+export const OrchestratorTaskAssigned = 'orchestrator:taskAssigned' as const;
+/** Orchestrator task completed. */
+export const OrchestratorTaskCompleted = 'orchestrator:taskCompleted' as const;
+/** Orchestrator task failed. */
+export const OrchestratorTaskFailed = 'orchestrator:taskFailed' as const;
+/** All phases completed successfully. */
+export const OrchestratorCompleted = 'orchestrator:completed' as const;
+/** Orchestrator error. */
+export const OrchestratorError = 'orchestrator:error' as const;
+```
+
+11 new events. Add to `SseEvent` namespace object + mirror in `constants.js`.
+
+### Step 7: State persistence — `src/state-store.ts` additions
+
+Add to `AppState`:
+```typescript
+orchestrator?: OrchestratorPersistState;
+```
+
+Add methods:
+```typescript
+getOrchestratorState(): OrchestratorPersistState | null;
+setOrchestratorState(state: Partial<OrchestratorPersistState>): void;
+clearOrchestratorState(): void;
+```
+
+### Step 8: Server integration — `src/web/server.ts` modifications
+
+1. Import `OrchestratorLoop` and `registerOrchestratorRoutes`
+2. Add `private orchestratorLoop: OrchestratorLoop` field
+3. Initialize in constructor (lazy — created on first start, not at boot)
+4. Add to `createRouteContext()` InfraPort: `orchestratorLoop: this.orchestratorLoop`
+5. Wire up OrchestratorLoop events → SSE broadcasts
+6. Register routes: `registerOrchestratorRoutes(this.app, ctx)`
+7. Clean up in `stop()`
+
+### Step 9: `src/web/public/orchestrator-ui.js` — Frontend panel
+~500 lines. New frontend module.
+
+**Load order**: After `panels-ui.js` (11), before `ralph-wizard.js` (13). So load order = 11.5.
+
+**UI elements:**
+- Goal input form (text area + config toggles)
+- Plan approval view (phase list, task details, approve/reject buttons)
+- Execution dashboard (progress bar, phase cards, task status indicators)
+- Agent activity panel (session count, team status)
+- Controls (pause, resume, stop, skip phase, retry phase)
+
+**SSE listeners:**
+- All 11 orchestrator events → update UI state
+- Reuses existing session/respawn/team event handlers for agent monitoring
+
+### Step 10: `src/prompts/orchestrator.ts` — Prompt templates
+~200 lines.
+
+Templates for:
+- Phase execution prompt (tells Claude what to do in this phase)
+- Team lead delegation prompt (instructs lead to create and coordinate teammates)
+- Verification prompt (asks Claude to verify phase output)
+- Replan prompt (gives failure context, asks for recovery steps)
+
+### Step 11: Constants, schemas, route barrel updates
+
+- `src/web/public/constants.js` — Add 11 SSE event mirrors
+- `src/web/schemas.ts` — Add Zod schemas for orchestrator API input validation
+- `src/web/routes/index.ts` — Export `registerOrchestratorRoutes`
+- `src/web/ports/infra-port.ts` — Add `orchestratorLoop` to InfraPort
+- `src/types/index.ts` — Export orchestrator types
+

+**Total modifications**: ~160 lines across 10 existing files
+
+## Implementation Execution Order
+
+This is the actual build order — each step is a commit checkpoint:
+
+1. **Types** — `src/types/orchestrator.ts` + barrel export. Zero risk, pure types.
+2. **SSE events** — Add all 11 events to both `sse-events.ts` and `constants.js`. Wire in SseEvent namespace.
+3. **State persistence** — Add orchestrator state to StateStore. Small, isolated change.
+4. **Schemas** — Add Zod validation schemas for API input.
+5. **Planner** — `src/orchestrator-planner.ts`. Can test in isolation.
+6. **Verifier** — `src/orchestrator-verifier.ts`. Can test in isolation.
+7. **Core loop** — `src/orchestrator-loop.ts`. The big one. Depends on planner + verifier.
+8. **Prompts** — `src/prompts/orchestrator.ts`. Templates used by core loop.
+9. **Port + routes** — `src/web/ports/infra-port.ts` update + `src/web/routes/orchestrator-routes.ts`.
+10. **Server integration** — Wire OrchestratorLoop into WebServer. Routes become live.
+11. **Frontend** — `src/web/public/orchestrator-ui.js` + app.js listeners + index.html script tag.
+12. **Tests** — `test/orchestrator-*.test.ts`.
+13. **Typecheck + lint** — Fix all issues, ensure CI passes.
+
+## Edge Cases & Error Handling
+
+- **Session limit reached**: Queue tasks and wait for sessions to free up (existing SessionManager handles this)
+- **All sessions crash during phase**: Mark phase as failed, attempt replan
+- **Verification flaky**: `moderate` mode allows test retries; `lenient` skips AI review
+- **Plan too large**: Cap at 10 phases, 50 total tasks. Warn user.
+- **Context overflow**: Auto-compact between phases. Respawn if needed (orchestrator state is external).
+- **User pauses mid-phase**: Pause task assignment, don't cancel running tasks. Resume picks up where it left off.
+- **Network/API errors during planning**: Retry plan generation up to 2 times, then fail with clear message.
+- **Orchestrator vs Ralph conflict**: Mutually exclusive. Starting orchestrator stops Ralph if running. Starting Ralph stops orchestrator.
+
+## Testing Strategy
+
+- **Unit tests**: `test/orchestrator-planner.test.ts` — phase grouping algorithm, team strategy assignment
+- **Unit tests**: `test/orchestrator-verifier.test.ts` — verification logic with mocked sessions
+- **Integration tests**: `test/orchestrator-loop.test.ts` — state machine transitions, task lifecycle
+- **Route tests**: `test/routes/orchestrator-routes.test.ts` — API validation, status responses
+
+All tests use `MockSession` pattern from existing test infrastructure. No real tmux needed.

+# Orchestrator Loop — Research Findings
+
+> Research doc for the new "Orchestrator Loop" feature. Not for GitHub.
+
+## What We're Building
+
+A new autonomous loop variant — **Orchestrator Loop** — that takes high-level user tasks, decomposes them into a detailed plan using team agents, and executes the plan step-by-step with quality gates. Unlike Ralph Loop (which executes a flat task queue), the Orchestrator coordinates **planning, delegation, and verification** as a continuous cycle.
+
+**Core idea**: User inputs a goal → Orchestrator creates a detailed plan → spins up team agents for parallel execution → validates each step → adapts the plan based on results → delivers polished output.
+
+## Existing Infrastructure Analysis
+
+### What We Can Reuse
+
+#### 1. Ralph Loop (`src/ralph-loop.ts`)
+- **Pattern**: Poll loop with `start() → tick() → stop()` lifecycle
+- **Reusable**: Event-driven task assignment, session completion handling, timeout management
+- **Limitation**: Flat task queue — no concept of phases, dependencies between task groups, or adaptive replanning
+- **Key insight**: `assignTaskToSession()` uses `session.sendInput(task.prompt)` — simple prompt injection into PTY
+
+#### 2. Task Queue (`src/task-queue.ts`) + Task (`src/task.ts`)
+- **Already has**: Priority ordering, dependency tracking between tasks, completion phrase detection
+- **Limitation**: No task *groups* or *phases*. Dependencies are task-to-task, not phase-to-phase
+- **Key insight**: Tasks support `completionPhrase` — a string the task watches for in output. This is how Ralph knows a task is done
+
+#### 3. Plan Orchestrator (`src/plan-orchestrator.ts`)
+- **Already has**: 2-agent plan generation (Research Agent → Planner Agent), TDD-aware plan items with P0/P1/P2 priorities
+- **Output**: `PlanItem[]` with dependencies, verification criteria, TDD phases, complexity ratings
+- **Limitation**: Plan generation only — no execution. Plans are generated then sit in state/UI for human review
+- **Key insight**: Uses `Session` directly to run Claude subagent instances for research and planning. Returns structured JSON
+
+#### 4. Team Agents (`src/team-watcher.ts`, `~/.claude/teams/`)
+- **Already has**: Team creation, member tracking, filesystem inbox messaging, task management via `~/.claude/tasks/{team-name}/`
+- **Limitation**: Codeman can only *observe* teams (TeamWatcher is read-only polling), not *create* or *orchestrate* them
+- **Key insight**: Teams are a Claude Code feature. Codeman monitors them but doesn't control them. We can't programmatically create teammates — Claude Code does that when you use `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+
+#### 5. Respawn Controller (`src/respawn-controller.ts`)
+- **Already has**: Preset-based automation (ralph-todo, overnight-autonomous), circuit breaker, health scoring
+- **Key insight**: The `ralph-todo` preset (8s idle, 480min max) is designed for autonomous task execution. We'd need a new preset or make Orchestrator Loop set its own timing
+
+#### 6. Session Auto-Ops (`src/session-auto-ops.ts`)
+- **Already has**: Auto-compact at token thresholds, auto-clear for context management
+- **Key insight**: Critical for long Orchestrator runs — prevents context overflow during multi-step execution
+
+#### 7. Hooks (`src/hooks-config.ts`)
+- **Already has**: `idle_prompt`, `stop`, `teammate_idle`, `task_completed` hook events
+- **Key insight**: Hooks fire POST to `/api/hook-event` — this is how Codeman knows when Claude is idle, stopped, or completed a task. The Orchestrator Loop can listen to these same events
+
+### What We Need to Build New
+
+1. **Plan → Task decomposition**: Convert PlanOrchestrator output (PlanItem[]) into executable task groups with phase ordering
+2. **Multi-phase execution engine**: Execute plan phases sequentially, tasks within phases in parallel
+3. **Verification gates**: After each phase, run verification (test commands, AI review) before proceeding
+4. **Adaptive replanning**: When a task fails or verification fails, generate a recovery plan
+5. **Team agent orchestration**: Leverage Claude Code's agent teams for parallel execution within phases
+6. **Progress tracking & UI**: Real-time dashboard showing plan progress, phase status, agent activity
+
+## How Teams Actually Work (Important Constraint)
+
+After deep research, here's the reality of agent teams:
+
+```
+User starts session with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
+  → Claude Code creates a team-lead
+  → Team-lead spawns teammates (in-process threads)
+  → Teammates appear as subagents (detected by SubagentWatcher)
+  → Communication via ~/.claude/teams/{name}/inboxes/{member}.json
+  → Tasks tracked in ~/.claude/tasks/{team-name}/{N}.json
+```
+
+**Codeman cannot programmatically create team members.** This is a Claude Code internal feature. However, Codeman CAN:
+- Start a session that has teams enabled
+- Send a prompt to the lead that instructs it to use agent teams
+- Monitor team activity via TeamWatcher
+- React to teammate_idle and task_completed hook events
+- Read team task status from the filesystem
+
+**This means**: The Orchestrator Loop orchestrates at the *session prompt* level, not the *team member* level. We tell the lead what to do, and the lead decides how to use its team.
+
+## Architecture Decision: Prompt-Level Orchestration
+
+Given the team constraint, the Orchestrator Loop works by:
+
+1. **Planning phase**: Use PlanOrchestrator to generate a detailed plan from user input
+2. **Execution phase**: Feed plan steps as prompts to sessions, one phase at a time
+3. **Verification phase**: After each phase, run verification prompts and check results
+4. **Adaptation phase**: If verification fails, generate recovery prompts
+
+The "team agents" aspect works by:
+- Starting sessions with `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+- Crafting prompts that *instruct the lead to delegate* to teammates
+- Monitoring team activity to track parallel progress
+- The lead agent is smart enough to decompose work across its team
+
+## Key Technical Findings
+
+### Session Input Mechanics
+```typescript
+// From session.ts - how we send prompts
+await session.sendInput(task.prompt);  // Uses writeViaMux() internally
+// writeViaMux() does: tmux send-keys -l "prompt text" + tmux send-keys Enter
+// CRITICAL: Single-line only! Multi-line breaks Ink rendering
+```
+
+### Completion Detection Chain
+```
+PTY output → RalphTracker.processData() → completion phrase fuzzy match
+  → CompletionConfidence scoring (multi-signal: promise tag + todos + exit signal)
+  → If confident → emit 'completionDetected'
+  → RalphLoop listens → marks task complete → assigns next
+```
+
+### How Plan Items Map to Tasks
+```typescript
+// PlanItem has:
+interface PlanItem {
+  id: string;            // "P0-001"
+  content: string;       // "Implement error handling for API endpoints"
+  priority: 'P0' | 'P1' | 'P2';
+  dependencies: string[]; // ["P0-000"] — other PlanItem IDs
+  verificationCriteria: string;
+  testCommand: string;
+  tddPhase: 'setup' | 'test' | 'impl' | 'verify' | 'review';
+  complexity: 'low' | 'medium' | 'high';
+}
+
+// Task has:
+interface CreateTaskOptions {
+  prompt: string;
+  priority: number;
+  dependencies: string[];  // Task IDs
+  completionPhrase: string;
+  timeoutMs: number;
+}
+
+// Natural mapping: PlanItem.content → Task.prompt
+// PlanItem.dependencies → Task.dependencies
+// PlanItem.priority → Task.priority (P0=100, P1=50, P2=10)
+// PlanItem.verificationCriteria → verification task prompt
+```
+
+### Context Management for Long Runs
+- Auto-compact at ~110k tokens (configurable)
+- Auto-clear at ~140k tokens (configurable)
+- Respawn cycling: kill + restart session to reset context entirely
+- For Orchestrator: we want compact between phases, respawn between major milestones
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| Context overflow during complex phases | High | Auto-compact between tasks, respawn between phases |
+| Team agents not predictable | Medium | Orchestrate at session level, let Claude decide team delegation |
+| Plan too ambitious → infinite loop | High | Phase budgets (max attempts per phase), circuit breaker |
+| Verification too strict → blocks progress | Medium | Configurable strictness, human override via UI |
+| Single-line prompt limit | Medium | Use CLAUDE.md file for complex instructions, prompt references file |
+| Long planning phase delays execution | Low | Show plan for approval before execution |

+/**
+ * @fileoverview Orchestrator Loop type definitions.
+ *
+ * Types for the phased plan execution system: state machine, plan structure,
+ * phase grouping, team strategies, verification, configuration, and persistence.
+ *
+ * Key exports:
+ * - OrchestratorState — state machine states (idle → planning → approval → executing → verifying → ...)
+ * - OrchestratorPlan / OrchestratorPhase / OrchestratorTask — hierarchical plan structure
+ * - TeamStrategy — how agents are coordinated per phase (single, parallel, team)
+ * - VerificationResult / VerificationCheck — phase verification output
+ * - OrchestratorConfig — user-configurable options
+ * - OrchestratorPersistState / OrchestratorStats — persistence and metrics
+ *
+ * Cross-domain relationships:
+ * - OrchestratorTask.queueTaskId links to TaskState.id (task domain)
+ * - OrchestratorTask.assignedSessionId links to SessionState.id (session domain)
+ * - OrchestratorPersistState is embedded in AppState.orchestrator (app-state domain)
+ *
+ * Served at `GET /api/orchestrator/status` and `GET /api/orchestrator/plan`.
+ * No dependencies on other domain modules.
