# Session Handover: S-2026-0214-2154

## Where We Are

Phase 3 (Operational Intelligence) is fully implemented, tested (96/96), and now visually verified via Playwright screenshots. The Playwright MCP permission issue from last session is resolved. T-058 Phase 3 is complete; Phase 4 (Autonomy) is not yet planned.

## Work in Progress

### T-058: Watchtower Command Center - Design Spec
- **Status:** started-work (Phase 3 complete, Phase 4 remains)
- **Last action:** Visual verification of /metrics, /patterns, and dashboard System Health row using Playwright screenshots — all render correctly
- **Next step:** Plan Phase 4 (Autonomy: scheduled audit, auto-healing, what-if) or mark Phase 3 as a milestone in the task file
- **Blockers:** None
- **Insight:** Playwright MCP on Linux Mint requires symlink: `sudo ln -sf /usr/bin/chromium /opt/google/chrome/chrome` since the auto-installer only supports Ubuntu/Debian

## Gaps Register

**3 spec-reality gap(s) being watched** — see `.context/project/gaps.yaml`

- **G-001** [high]: Enforcement tiers are spec-only
- **G-004** [low]: Multi-agent collaboration untested
- **G-005** [medium]: Graduation pipeline has no tooling

## Decisions Made This Session

1. **Symlink Chromium to Chrome path for Playwright**
   - Why: Playwright MCP plugin hardcodes `/opt/google/chrome/chrome`; auto-installer fails on Linux Mint
   - Alternatives rejected: Installing Google Chrome separately (heavier, unnecessary)

## Things Tried That Failed

1. **`mcp__plugin_playwright_playwright__browser_install`** — Playwright's installer only supports Ubuntu/Debian, fails on Linux Mint with "cannot install on linuxmint distribution"
2. **`npx playwright install chromium`** — Downloads headless shell to cache but plugin still looks for `/opt/google/chrome/chrome`

## Open Questions / Blockers

1. Phase 4 scope not yet defined — needs brainstorming session

## Gotchas / Warnings for Next Session

- Web server is running on :3000
- Playwright works now via symlink (`/opt/google/chrome/chrome` -> `/usr/bin/chromium`)
- Playwright permissions are in `~/.claude/settings.json` allow list: `mcp__plugin_playwright_playwright__*`
- Screenshots saved as `metrics-page.png`, `patterns-page.png`, `dashboard-page.png` in project root (not committed, can be deleted)

## Suggested First Action

Decide whether to plan Phase 4 (Autonomy) for T-058 or move on to other work. If Phase 4, use the brainstorming skill first.

## Files Changed This Session

- Created: `/opt/google/chrome/chrome` (symlink to `/usr/bin/chromium`)
- No code changes — this was a verification-only session
