# Code Review Summary

**Branch**: feat-interactive-orchestrator-mode -> main
**Date**: 2026-05-06_2328
**PR**: #159

## Merge Recommendation: CHANGES_REQUESTED

Multiple reviewers identified **blocking issues in your changes**: (1) the CLI handler directly performs service-layer orchestration lifecycle management instead of delegating to the service layer, violating established layering boundaries; (2) the test file with 60 tests is not included in any test group, so they will never run in CI; (3) missing `container.get()` validation that could leave the DB in an inconsistent state; (4) a HIGH-severity PID validation gap that enables SIGTERM to arbitrary processes.

These are solvable but require architectural fixes before merge. **Performance review approved** (9/10). **Regression analysis shows no lost functionality** (9/10). Architecture and consistency have clear blocking paths.

## Blocking Issues

### HIGH Severity (6 issues)

#### 1. CLI handler bypasses service layer for orchestration lifecycle — Architecture (88% confidence)
**Location**: `src/cli/commands/orchestrate.ts:695-733, 792-809`

**Problem**: `handleOrchestrateInteractive` manually resolves `agentRegistry`, `eventBus`, and `orchestrationRepository` from the DI container, then performs orchestration lifecycle management (status transitions, event emission, process spawning) inline. This violates Clean Architecture — the CLI layer is performing service-layer work. Compare to `handleOrchestrateForeground` which delegates to `OrchestrationManagerService`.

**Impact**: Lifecycle logic is split across two layers, making both harder to test and maintain. Changes to orchestration status management must be coordinated across `orchestration-manager.ts` and `orchestrate.ts`.

**Fix**: Extract spawn + wait + status transition + event emission into `OrchestrationManagerService` (e.g., `runInteractiveOrchestration` method). The CLI handler should call the service and receive a result, mirroring the standard creation flow. The service already has access to `eventBus` and `orchestrationRepo`.

---

#### 2. Code duplication between createOrchestration and createInteractiveOrchestration — Architecture (85% confidence), Complexity (88% confidence)
**Location**: `src/services/orchestration-manager.ts:330-368, 74-94, 101-124`

**Problem**: `createInteractiveOrchestration` duplicates 40+ lines of validation and state file setup that are identical to `createOrchestration` (goal validation, working directory validation, agent resolution, state file creation). When bugs are fixed in one path, the other may miss the fix.

**Impact**: Maintenance burden doubles for any change to the create flow. The interactive variant is **missing the compensation/cleanup pattern** present in the standard path (line 157) — if `orchestrationRepo.save()` succeeds but a later step fails, the state file is orphaned.

**Fix**: Extract the shared validation + state file setup into a private method (`prepareOrchestration(request)`), then have both methods call it. Add the same compensation path to `createInteractiveOrchestration` for save failure cleanup.

---

#### 3. handleOrchestrateInteractive exceeds 140 lines with cyclomatic complexity ~12 — Complexity (90% confidence)
**Location**: `src/cli/commands/orchestrate.ts:684-823`

**Problem**: This function bundles at least 7 distinct concerns: setup, DI lookups, process spawning, signal coordination, process exit awaiting, status determination, DB updates, event emission, UI output, cleanup. It has 6 early-exit branches, a SIGINT handler block, 3-way status branching, nested conditional events, and conditional UI output.

**Impact**: Difficult to test in isolation, high cognitive load for modifications.

**Fix**: Extract phases into named helpers:
```typescript
const spawnCtx = await setupInteractiveSpawn(parsed);
const exitCode = await awaitInteractiveChild(spawnCtx);
await finalizeInteractiveOrchestration(spawnCtx, exitCode);
```
Each phase would be 20-40 lines with clear responsibility.

---

#### 4. Unchecked `container.get()` results for eventBus and orchestrationRepository — TypeScript (95% confidence)
**Location**: `src/cli/commands/orchestrate.ts:731-733`

**Problem**: Two `container.get()` calls retrieve services without checking `.ok`. If both fail, the orchestration finishes but neither emits events nor updates the DB status, leaving the row stuck at RUNNING forever. Other call sites in the same file check `.ok` and exit on failure (lines 47, 477, 695).

**Impact**: Silent service failures could cause database inconsistency.

**Fix**: Check both results immediately after `.get()` and exit on failure, matching the `agentRegistryResult` pattern above (line 695-700):
```typescript
if (!eventBusResult.ok) {
  ui.error(`Failed to get event bus: ${eventBusResult.error.message}`);
  await container.dispose();
  process.exit(1);
}
if (!orchRepoResult.ok) {
  ui.error(`Failed to get orchestration repository: ${orchRepoResult.error.message}`);
  await container.dispose();
  process.exit(1);
}
```

---

#### 5. Test file not included in any test group script — Testing (95% confidence)
**Location**: `tests/unit/interactive-orchestrator.test.ts`

**Problem**: The new test file (60 tests) is not included in any `package.json` test group script. The `test:orchestration` group explicitly lists orchestration-related test files but omits this one. These 60 tests will never run in CI or via `npm run test:all`.

**Impact**: New feature lacks CI test coverage.

**Fix**: Add the file to the `test:orchestration` group in `package.json`:
```json
"test:orchestration": "NODE_OPTIONS='--max-old-space-size=2048' vitest run tests/unit/core/orchestrator-state.test.ts tests/unit/core/orchestrator-scaffold.test.ts tests/unit/implementations/orchestration-repository.test.ts tests/unit/services/orchestration-manager.test.ts tests/unit/services/orchestrator-prompt.test.ts tests/unit/services/orchestrator-prompt-snippets.test.ts tests/unit/services/handlers/orchestration-handler.test.ts tests/unit/cli/orchestrate.test.ts tests/unit/cli/orchestrate-init.test.ts tests/unit/cli/orchestrate-foreground.test.ts tests/unit/interactive-orchestrator.test.ts tests/integration/orchestration-lifecycle.test.ts --no-file-parallelism"
```

---

#### 6. PID stored in DB without validation — enables SIGTERM to arbitrary process — Security (85% confidence)
**Location**: `src/services/orchestration-manager.ts:419-424, 476-484`

**Problem**: `updateInteractiveOrchestrationPid` accepts any `number` and stores it without validation. The `cancelOrchestration` path then calls `process.kill(orchestration.pid, 'SIGTERM')` on whatever PID is stored. While the PID currently originates from a trusted source, there is no defense-in-depth validation that the PID is positive, non-zero, and belongs to a legitimate process. The codebase validates `orchestratorId` format with a regex before using it in env vars — the same approach should apply to PIDs.

**Impact**: If the DB is corrupted or the API is called with a crafted PID (e.g., PID 1 to kill init), SIGTERM could be sent to an arbitrary process.

**Fix**: Add PID range validation at both the storage and kill boundaries:
```typescript
// In updateInteractiveOrchestrationPid:
if (!Number.isInteger(pid) || pid <= 0) {
  return err(new AutobeatError(ErrorCode.INVALID_INPUT, `Invalid PID: ${pid}`));
}

// In cancelOrchestration, before process.kill:
if (orchestration.pid && orchestration.pid > 0) {
  try {
    process.kill(orchestration.pid, 'SIGTERM');
  } catch { /* ESRCH */ }
}
```

---

### MEDIUM Severity (8 issues)

#### 1. Missing CHECK constraint on orchestrations.mode column — Architecture (84% confidence), Consistency (85% confidence), TypeScript (85% confidence)
**Location**: `src/implementations/database.ts:993-994`

**Problem**: Migration v25 adds `mode TEXT DEFAULT NULL` without a CHECK constraint. The codebase has an established pattern: `status` columns in migrations v2, v3, v4, v10, v11, v14, v22, v24 all include CHECK constraints. This is documented as "defense-in-depth" — the DB enforces invariants regardless of code path.

**Impact**: Invalid mode values (typos, corruption) can be persisted without database-level validation. A row with `mode = 'admin'` could bypass mode-specific branching in `cancelOrchestration` and `checkOrchestrationLiveness`.

**Fix**: Change migration to:
```sql
ALTER TABLE orchestrations ADD COLUMN mode TEXT DEFAULT NULL
  CHECK(mode IS NULL OR mode IN ('standard', 'interactive'));
```

---

#### 2. Removed DECISION comment without replacement — Consistency (82% confidence)
**Location**: `src/cli/commands/orchestrate.ts:835`

**Problem**: A DECISION comment documenting why `validatePath` is called without `mustExist` in `handleOrchestrateInit` was removed. The comment explained: "DECISION: validatePath without mustExist -- workingDirectory is only embedded in the printed usage snippet, not created on disk. Scaffold files go to ~/.autobeat/. Requiring existence would reject valid future directories with no security benefit." CLAUDE.md's feedback documents that DECISION comments are acceptance criteria and design documentation.

**Impact**: Loss of design reasoning; future maintainers won't understand the rationale.

**Fix**: Restore the DECISION comment above the `if (parsed.workingDirectory)` block in `handleOrchestrateInit`.

---

#### 3. cleanup() called with orchestration ID instead of task-scoped ID — Consistency (90% confidence)
**Location**: `src/cli/commands/orchestrate.ts:819`

**Problem**: `adapter.cleanup(orchestration.id)` passes an orchestration ID to a method documented as `cleanup(taskId: string)`. The interface expects a task ID. For the Gemini adapter, this constructs a file path using `${taskId}.md` to delete the system prompt temp file. Since `spawnInteractive` calls `resolveSpawnConfig` without a deterministic `taskId`, the temp file is created with a random UUID fragment, which will never match `orchestration.id`. The cleanup becomes a silent no-op, **leaking the temp file on disk**.

**Impact**: Temp files accumulate on the user's filesystem.

**Fix**: Pass the orchestration ID as the `taskId` parameter in `resolveSpawnConfig` so temp files are named with a deterministic ID matching the cleanup call:
```typescript
// In handleOrchestrateInteractive, ensure orchestration.id flows to resolveSpawnConfig
// so the temp file naming is consistent with the cleanup call.
```

---

#### 4. handleOrchestrateInteractive lacks top-level try/catch — Consistency (82% confidence)
**Location**: `src/cli/commands/orchestrate.ts:684`

**Problem**: `handleOrchestrateInteractive` lacks a top-level try/catch unlike `handleOrchestrateForeground` (which wraps the entire body and calls `container.dispose()` + `process.exit(1)` on any unexpected error). If any awaited operation throws unexpectedly, the function will leak the container and the child process.

**Impact**: Inconsistent error handling patterns; resource leaks.

**Fix**: Wrap the function body in try/catch with cleanup, matching the foreground handler's pattern.

---

#### 5. Duplicated output block in handleOrchestrateInit — Complexity (82% confidence)
**Location**: `src/cli/commands/orchestrate.ts:862-923`

**Problem**: The `if (isInteractive) { ... } else { ... }` block contains two large `process.stdout.write()` calls (~60 lines total). Both branches share 12 lines of identical "instruction snippets" suffix. The structural difference is only ~5 lines.

**Impact**: Maintenance burden when updating instruction snippets.

**Fix**: Build the shared instruction snippet array once, then prepend mode-specific headers:
```typescript
const commonSnippets = [
  '--- Delegation Instructions ---', s.instructions.delegation,
  '', '--- State Management Instructions ---', s.instructions.stateManagement,
  '', '--- Constraint Instructions ---', s.instructions.constraints, '',
];
const header = isInteractive ? [...interactiveHeader] : [...standardHeader];
process.stdout.write(['', ...header, '', ...commonSnippets].join('\n'));
```

---

#### 6. createInteractiveOrchestration skips state file cleanup on save failure — TypeScript (82% confidence)
**Location**: `src/services/orchestration-manager.ts:376-382`

**Problem**: When `orchestrationRepo.save(orchestration)` fails, the method returns an error but does not clean up the state file written at line 361. The standard `createOrchestration` method has an explicit `cleanupFiles()` helper for this path (line 157). The interactive variant omits it.

**Impact**: Orphaned state files on save failure.

**Fix**: Add state file cleanup in the save failure path:
```typescript
if (!saveResult.ok) {
  this.logger.error('Failed to save interactive orchestration', saveResult.error, {
    orchestratorId: orchestration.id,
  });
  try { unlinkSync(stateFilePath); } catch { /* orphan files are harmless */ }
  return err(saveResult.error);
}
```

---

#### 7. Direct container.get() calls bypass service abstraction — Consistency (80% confidence)
**Location**: `src/cli/commands/orchestrate.ts:731-733`

**Problem**: `handleOrchestrateInteractive` directly calls `container.get('eventBus')` and `container.get('orchestrationRepository')` to perform DB updates and event emission. Meanwhile, `orchestrationService` (already obtained via `withServices`) has methods for these operations. The foreground handler uses `service.cancelOrchestration()` through the service layer. The interactive handler bypasses the service for status updates and event emission, creating an inconsistent access pattern.

**Impact**: Inconsistent abstraction boundaries; harder to test; service layer responsibilities are split across handlers.

**Fix**: Add a method to `OrchestrationService` (e.g., `completeInteractiveOrchestration(id, status)`) that handles DB update + event emission, and call it from the CLI handler instead of reaching into the container directly.

---

#### 8. Missing tests for updateInteractiveOrchestrationPid and cancel with stored PID — Testing (90% confidence and 82% confidence)
**Location**: `src/services/orchestration-manager.ts:419-425, 476-484`

**Problem**: 
- `updateInteractiveOrchestrationPid` has zero test coverage. The happy path (PID persisted) and error path (orchestration not found) are untested.
- The cancel path with stored PID calls `process.kill(orchestration.pid, 'SIGTERM')` but this branch is never exercised in tests.

**Impact**: Key service behavior is unverified.

**Fix**: Add tests:
```typescript
it('should persist PID via updateInteractiveOrchestrationPid', async () => {
  const createResult = await service.createInteractiveOrchestration({ goal: 'Test' });
  if (!createResult.ok) return;
  const pidResult = await service.updateInteractiveOrchestrationPid(
    createResult.value.orchestration.id,
    12345,
  );
  expect(pidResult.ok).toBe(true);
  const dbResult = await orchestrationRepo.findById(createResult.value.orchestration.id);
  expect(dbResult.value!.pid).toBe(12345);
});

it('should attempt SIGTERM when interactive orchestration has stored PID', async () => {
  const createResult = await service.createInteractiveOrchestration({ goal: 'Test' });
  if (!createResult.ok) return;
  await service.updateInteractiveOrchestrationPid(
    createResult.value.orchestration.id,
    99999,
  );
  const cancelResult = await service.cancelOrchestration(createResult.value.orchestration.id);
  expect(cancelResult.ok).toBe(true);
});
```

## Should-Address Issues (7 issues)

### MEDIUM Severity

#### 1. Orchestration object construction uses Object.freeze spread override — Architecture (85% confidence)
**Location**: `src/services/orchestration-manager.ts:370-374`

**Problem**: Interactive orchestration construction bypasses the `createOrchestration` factory function by spreading its result and overriding `status` and `mode` via `Object.freeze({...createOrchestration(...), status: RUNNING, mode: 'interactive'})`. The project consistently uses factory functions + `updateOrchestration()` for domain object creation.

**Impact**: If `createOrchestration` gains new mandatory fields or validation, the interactive path silently skips them.

**Recommendation**: Either (a) extend `createOrchestration` to accept optional `mode` and initial `status` parameters, or (b) use the factory then call `updateOrchestration(orchestration, { status: RUNNING, mode: 'interactive' })` as a two-step pattern.

---

#### 2. SIGINT handler manipulation is fragile — Architecture (82% confidence)
**Location**: `src/cli/commands/orchestrate.ts:764-781`

**Problem**: The interactive handler removes all SIGINT listeners (`process.removeAllListeners('SIGINT')`), installs its own, and attempts to restore the original listeners. This is fragile: if a listener is added between save and restore (e.g., by the container), it will be lost. The cast `handler as NodeJS.SignalsListener` silently suppresses type errors.

**Impact**: If an intermediate component adds SIGINT handlers (e.g., database cleanup listener), they are permanently lost, leaving resources unclean.

**Recommendation**: Add a double-Ctrl+C safety mechanism or use `AbortController` with `signal` for modern Node.js cancellation pattern.

---

#### 3. ScaffoldResult fields changed from required to optional — TypeScript (82% confidence)
**Location**: `src/core/orchestrator-scaffold.ts:38-39`

**Problem**: `exitConditionScript` and `suggestedExitCondition` changed from required `string` to optional `string | undefined`. This weakens the interface contract — existing and future consumers must defensively handle undefined for what were previously guaranteed fields.

**Impact**: All future callers of `ScaffoldResult` must add null-coalescing guards.

**Recommendation**: Use a discriminated union: `ScaffoldResult = StandardScaffoldResult | InteractiveScaffoldResult`. The standard variant keeps required fields; the interactive variant omits them. This preserves type safety for both paths.

---

#### 4. Sync I/O (readFileSync + spawnSync) on every interactive spawn — Performance (82% confidence)
**Location**: `src/implementations/base-agent-adapter.ts:268`, `src/core/agents.ts:212`

**Problem**: `resolveSpawnConfig()` calls `loadAgentConfig()` (which does `readFileSync` + JSON.parse) and `isCommandInPath()` (which executes `spawnSync('which', ...)`). Both are blocking operations. For interactive spawn, this blocks the event loop during setup. This pattern existed pre-PR but is inherited by the interactive path.

**Impact**: For interactive mode, this is a one-time cost at session start (not per-request), so practical impact is negligible.

**Recommendation**: No action needed for this PR (pre-existing design choice). If ever called in a hot loop, consider caching `loadAgentConfig` and `which` binary existence.

---

#### 5. file length: orchestrate.ts is 1000 lines — Complexity (85% confidence)
**Location**: `src/cli/commands/orchestrate.ts`

**Problem**: The file is exactly 1000 lines, well above the 500-line warning threshold. Adding interactive mode brought it from ~680 to 1000 lines. It contains 17 functions spanning arg parsing, detach handling, foreground handling, status, list, cancel, interactive handling, init, and dispatcher.

**Impact**: High navigation and cognitive load.

**Recommendation**: Consider splitting into `orchestrate-interactive.ts` (containing `handleOrchestrateInteractive` + `parseOrchestrateInteractiveArgs`) and keeping the rest in `orchestrate.ts`.

---

#### 6. orchestration-manager.ts exceeds threshold with duplicate validation — Complexity (80% confidence)
**Location**: `src/services/orchestration-manager.ts`

**Problem**: `createOrchestration` (~230 lines) and `createInteractiveOrchestration` (~90 lines) together with `cancelOrchestration` (~70 lines) make the service dense. The validation duplication exacerbates cognitive load.

**Impact**: High maintainability cost.

**Recommendation**: Extract shared validation into a private method. That alone would reduce the file by ~40 lines and improve clarity.

---

#### 7. --dangerously-skip-permissions in interactive mode exposes user to unrestricted agent actions — Security (80% confidence)
**Location**: `src/implementations/claude-adapter.ts:29-32`

**Problem**: `buildInteractiveArgs` includes `--dangerously-skip-permissions` which gives the Claude CLI full autonomy (file writes, command execution, network access) without per-action approval. Unlike headless mode (where `--print` limits to stdout-only), interactive mode shows the user a live session. The flag means the agent will execute actions without prompting, even though the user is watching the terminal.

**Impact**: User might reasonably expect to be prompted before destructive actions in interactive mode.

**Recommendation**: This is likely a conscious design decision. If intentional, add a DECISION comment explaining the rationale. If the intent is for users to maintain approval control, remove the flag.

---

## Pre-existing Issues (3 issues, Informational Only)

#### 1. Removed DECISION comments from resolveSpawnConfig refactoring
**Location**: `src/implementations/base-agent-adapter.ts:370`

**Problem**: The `spawn()` method previously contained inline DECISION comments explaining resolution order. These were removed during the refactoring to `resolveSpawnConfig()`, but no equivalent comments were added to the shared method.

#### 2. process.env full-copy on every spawn
**Location**: `src/implementations/base-agent-adapter.ts:329-333`

**Problem**: `buildSpawnEnv()` copies the entire environment on every spawn (O(env_vars) per spawn). This is trivially fast but could be a module-level constant.

#### 3. Regex compiled on every spawn
**Location**: `src/implementations/base-agent-adapter.ts:336`

**Problem**: `ORCHESTRATOR_ID_RE` is re-compiled inside `buildSpawnEnv()` on every call. Not a practical bottleneck but could be module scope.

---

## Key Insights

1. **Layering violation is the root issue**: The CLI handler performing service-layer orchestration lifecycle management cascades into the complexity and consistency problems. Fixing this single architectural issue resolves the duplicated validation, inconsistent error handling, and container.get() patterns.

2. **Defense-in-depth pattern established but incomplete**: The CHECK constraint gap on the `mode` column is the only DB constraint omission across all enum-like columns in the schema. This is easily fixed and prevents a class of edge-case bugs.

3. **Test coverage gap blocks CI**: The 60 new tests exist but won't run in CI. This is a quick fix (one line to package.json) with high impact.

4. **Service method `updateInteractiveOrchestrationPid` is unverified**: A security-sensitive method storing PIDs used for process termination has zero test coverage. The test additions are straightforward and critical.

5. **Performance is solid**: Interactive mode introduces minimal overhead. The shared `resolveSpawnConfig()` avoids duplication without performance cost. No polling, no busy-wait. Design choice to skip the loop iteration machinery for interactive mode is correct.

6. **Regression risk is low**: All existing functionality is preserved. The type widening on `ScaffoldResult` is safe for existing callers (standard path always defines the fields). Backward compatibility confirmed across migration, repositories, and service layers.
