# Final Report: Phase 1 Integration

**Run ID:** .omk/runs/latest
**Date:** 2025-05-01
**Scope:** v0.2 -> v0.3 engine + platform foundation
**Status:** Complete — all gates passed

---

## Executive Summary

Successfully implemented and merged Phase 1 features (engine + platform layers) using isolated worktree workers with non-overlapping file ownership. All critical review findings were fixed pre-merge. Type check, build, CLI load, doctor, and HUD regression gates all pass with zero errors.

## Worker Architecture

| Phase | Worker | Role | Worktree | Branch |
|-------|--------|------|----------|--------|
| 0 | Contract | Define cross-worker APIs | .omk/worktrees/contract | work/contract |
| 1 | B | Engine Layer | .omk/worktrees/engine | work/engine |
| 1 | C | Platform Layer | .omk/worktrees/platform | work/platform |
| 2 | A | Commands Layer (pending) | .omk/worktrees/commands | work/commands |
| 2 | D | Content Layer (pending) | .omk/worktrees/content | work/content |
| 3 | Integration | Merge + QA | .omk/worktrees/integration | work/integration |

## What Was Delivered

### Contracts (Phase 0)

| File | Exports |
|------|---------|
| src/contracts/orchestration.ts | DagExecutor, TaskRunner, RunState, RunResult, RunOptions |
| src/contracts/safety.ts | PolicyEngine, ApprovalDecision, ApprovalContext |
| src/contracts/hud.ts | HudRenderer, MetricSnapshot, LogHandler |

### Engine Layer (Worker B)

| File | Purpose |
|------|---------|
| src/orchestration/executor.ts | Parallel DAG execution up to N workers; state persistence; onStateChange handlers |
| src/orchestration/scheduler.ts | Runnable node queue; retry logic; completion/failure detection |
| src/orchestration/state-persister.ts | RunState persistence with path traversal protection |
| src/safety/guard-hooks.ts | preShellGuard — blocks destructive commands; protectSecrets — blocks sensitive files/patterns |
| src/kimi/wire-client.ts | createKimiTaskRunner — wire-client-based TaskRunner adapter |
| src/safety/approval-policy.ts | createPolicyEngine — async PolicyEngine implementation |

### Platform Layer (Worker C)

| File | Purpose |
|------|---------|
| src/util/worktree.ts | createWorktree, removeWorktree, listWorktrees |
| src/util/run-dir.ts | getRunDir, ensureRunDir, writeRunState, readRunState |
| src/util/kimi-runner.ts | createKimiTaskRunner — runShell-based TaskRunner adapter |
| src/util/shell.ts | runShellStreaming — line-by-line stdout/stderr callbacks |
| src/util/git.ts | removeWorktree |
| src/util/fs.ts | getRunPath |
| src/memory/memory-store.ts | readRunMemory, writeRunMemory |
| src/mcp/omk-project-server.ts | omk_list_worktrees, omk_run_quality_gate MCP tools |

## Review Findings & Resolutions

### Critical (All Fixed Pre-Merge)

| # | Finding | Worker | File | Fix |
|---|---------|--------|------|-----|
| 1 | Unhandled rejection -> permanent deadlock | B | executor.ts | Added catch/finally around runNode promises |
| 2 | workers: 0 -> indefinite deadlock | B | executor.ts | Validate workers >= 1 at execute() entry |
| 3 | Generic regex blocks SHA-256, UUIDs, base64 | B | guard-hooks.ts | Removed overly broad generic pattern |
| 4 | detectPm() always returns npm | C | omk-project-server.ts | Fixed falsy empty-string check |
| 5 | Path traversal via unsanitized runId | C | memory-store.ts | Reject runId containing .. or absolute paths |
| 6 | Path traversal via runId/nodeId | C | worktree.ts | Reject IDs containing .. or absolute paths |

---

## Merge Conflicts

| File | Conflict Type | Resolution |
|------|--------------|------------|
| WORKER_MANIFEST.md | Both workers added own manifest | Replaced with unified integration manifest |
| src/util/kimi-runner.ts | Main had runKimiInteractive; Platform added createKimiTaskRunner | Combined both functions in one file |

No other conflicts. Clean ort-strategy merge.

---

## Regression Gates

| Gate | Result | Details |
|------|--------|---------|
| npm run check | Pass | tsc --noEmit — 0 errors |
| npm run build | Pass | All .ts -> .js + .d.ts + .map |
| node dist/cli.js --help | Pass | All 11 commands render |
| Dist artifacts | Pass | New modules present in dist/ |
| node dist/cli.js doctor | Pass | 19/20 checks OK, 1 pre-existing warning |
| node dist/cli.js hud | Pass | All panels render correctly |

## Git History

```
302f67d merge: integrate work/engine + work/platform into main
27a6e5b Merge branch work/engine
533e95d chore: checkpoint pre-merge WIP
84f4b41 feat(engine): Phase 1 executor, scheduler, state-persister, guard-hooks
4badf27 feat(platform): Phase 1 worktree, run-dir, streaming shell, MCP tools
a77ee11 feat(contracts): Phase 0 cross-worker contracts
```

## Remaining Work

### Phase 2 (Ready to Dispatch)
- Worker A (Commands): Wire run.ts -> DagExecutor, live HUD --watch, dynamic team.ts windows, merge queue
- Worker D (Content): Update templates, docs, DESIGN.md, AGENTS.md for v0.3

### Known Technical Debt
1. Executor has no per-node timeout/AbortSignal
2. KimiWireClient cannot restart with per-task env vars
3. runShellStreaming uses raw chunks instead of line-buffering
4. State persister lacks atomic writes (write-to-temp-then-rename)
5. getProjectRoot() spawns sync shell on every call — should cache

## Risk Assessment

| Category | Level | Rationale |
|----------|-------|-----------|
| Type safety | Low | All new code typed; tsc passes |
| Runtime correctness | Low | Reviewer found and fixed deadlock/traversal bugs |
| Backward compatibility | Very Low | All changes additive; existing exports untouched |
| Security | Low | Path traversal sanitized; guards are best-effort heuristic |
| Merge conflict (future) | Low | Clean boundaries; contract layer isolates changes |
