# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-01-29)

**Core value:** Fix security vulnerabilities and bugs, refactor architecture for maintainability, and establish comprehensive test coverage.
**Current focus:** Phase 5 complete - Release readiness baseline established

## Current Position

Phase: 5 of 5 (Test Infrastructure Hardening)
Plan: 3 of 3 (05-03 completed)
Status: Phase complete
Last activity: 2026-02-17 — Completed quick task 005: Review improvements and reduce redundancies

Progress: [██████████] 10/10 plans complete

## Performance Metrics

**Velocity:**
- Total plans completed: 10
- Average duration: 6 min
- Total execution time: 1.04 hours

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 01-command-injection-elimination | 1 | 2 min | 2 min |
| 02-bug-fixes | 1 | 2 min | 2 min |
| 03-architecture-refactoring | 2 | 15 min | 8 min |
| 04-test-coverage | 3 | 30 min | 10 min |
| 05-test-infrastructure-hardening | 3 | 18 min | 6 min |

**Recent Trend:**
- Last 5 plans: 05-03 (6 min), 05-02 (7 min), 05-01 (5 min), 04-03 (8 min), 04-02 (10 min)
- Trend: Phase 5 completed with OAuth hardening, cache observability, and reproducible benchmark/load regression gates

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- Use execFile over exec for shell commands (prevents injection by avoiding shell interpolation)
- Zod for tool input validation (already a dependency, type-safe, standard approach)
- Warn (not crash) when keytar unavailable (graceful degradation is existing pattern)
- Validate cookies with /^[a-zA-Z0-9_-]+$/ regex for defense-in-depth (01-01)
- Restructured roadmap: old Phase 3 replaced with Phases 3-5 based on 004-REVIEW-REPORT (24 recommendations)
- Dynamic import for server module so CLI commands skip heavy MCP SDK loading (03-01)
- Removed unreliable YouTube global status warning from handler (03-02)
- Kept YouTube returning Video[] instead of YouTubeResult wrapper for simplicity (03-02)
- OAuth callback flow now resolves only after server close to avoid callback port races (04-01)
- Setup CLI helper logic extracted into `setup-utils` for deterministic unit testing (04-02)
- CI-only keytar mocking added in Vitest setup; local runs keep real keytar behavior (04-03)
- Vitest excludes hidden tooling directories to keep full-suite runs deterministic (04-03)
- Coverage enforcement uses Vitest V8 provider and CI runs `test:coverage` as a merge gate (05-01)
- Handler tests now share deterministic fixtures/harness under `src/__tests__/fixtures` and `src/tools/handlers/__tests__/harness.ts` (05-01)
- ESLint now blocks focused tests in all test files and enforces deterministic fixture generation for handler suites (05-01)
- HTTP and inflight-dedup utilities now have explicit timeout/abort/failure/concurrency path tests (05-02)
- Free source suites now assert parser failures, malformed entries, and degraded upstream behavior without throwing (05-02)
- Cache and intent cache tests now cover corruption/unreadable entries, sanitization collisions, and miss/hit accounting edge paths (05-02)
- Patreon OAuth now uses state + PKCE (S256) and rejects missing/mismatched callback state (05-03)
- FileCache exposes hit/miss observability via getStats with memory/file hit breakdown and reset on clear (05-03)
- Benchmark and load-test automation now provide five-scenario baselines plus 10-concurrency guardrail validation (05-03)
