# Session Handover: S-2026-0215-0954

## Where We Are

Major governance investigation (T-061) completed and remediated. The core principle "Nothing gets done without a task" was being bypassed by third-party plugins that aren't aware of framework rules. Built 4-layer defense in depth: CLAUDE.md instruction precedence, PreToolUse hook (check-active-task.sh), `fw work-on` command, and `/start-work` command. The PreToolUse hook is the only structural enforcement — it blocks Write/Edit tools when no active task is set. **Takes effect next session** (hooks snapshot at start). Also enhanced the timeline page (T-060) with inline task names and truncated session narratives.

## Work in Progress

### T-067: Plugin onboarding audit — task-awareness check for new plugins
- **Status:** captured (backlog)
- **Last action:** Created as remediation task from T-061 investigation
- **Next step:** Design a script/checklist that scans new plugin skill files for task-system references
- **Blockers:** None — lower priority than the enforcement tasks that are now complete
- **Insight:** Need a repeatable process to run whenever a plugin is added to settings.json

### T-070: Session handover S-2026-0215-0837
- **Status:** started-work (this handover)
- **Last action:** Generating end-of-session handover
- **Next step:** Commit and close
- **Blockers:** None
- **Insight:** N/A

## Gaps Register

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

- **G-004** [low]: Multi-agent collaboration untested
- **G-005** [medium]: Graduation pipeline has no tooling

Run `fw audit` to check if any trigger conditions are met.

## Decisions Made This Session

1. **D-011: G-001 decision trigger has fired — build enforcement (not simplify)**
   - Why: 4-agent investigation confirmed 0/20 plugins are task-aware; bypass happened 3 times in one session
   - Alternatives rejected: "Simplify spec" — the bypass is real and recurring, not theoretical

2. **PreToolUse hook (exit code 2) as primary enforcement, not Bash hooks**
   - Why: Only Write/Edit tools modify code; Bash is too broad (legitimate uses everywhere)
   - Alternatives rejected: Bash matcher (too many false positives), SessionStart-only check (doesn't catch mid-session work)

3. **Project command (`/start-work`) instead of full plugin skill**
   - Why: Simpler, project-specific, no plugin packaging needed
   - Alternatives rejected: Full plugin fork of superpowers (heavy, maintenance burden)

## Things Tried That Failed

1. **Instruction precedence in CLAUDE.md alone** — Agent bypassed task-first rule 2 more times AFTER adding it. Documentation-only enforcement does not work. Proves P-002 is correct.
2. **YAML parsing without error handling** — Some task files have colons in `name:` field (e.g. "Web UI foundation: Flask + htmx"). Added try/except yaml.YAMLError.
3. **Playwright MCP without --no-sandbox** — Fails as root. Added `--no-sandbox` to both .mcp.json locations. Takes effect next session.

## Open Questions / Blockers

1. Will the PreToolUse hook cause problems with legitimate framework operations? Exempt paths (.context/, .tasks/, .claude/, .git/) should cover it, but watch for edge cases.
2. Tier 0 enforcement (destructive Bash commands) is still spec-only — needs command parsing which is complex and error-prone. Is it worth building?
3. Plugin onboarding (T-067) — should this be a `fw doctor` check or a standalone script?

## Gotchas / Warnings for Next Session

- **PreToolUse hook is NEW** — first session with it active. Watch for false positives on exempt paths.
- **Playwright --no-sandbox fix is NEW** — verify it works by navigating to localhost:3000.
- **Web server must be restarted** after code changes to web/ files (it doesn't auto-reload).
- **Hooks snapshot at session start** — any changes to .claude/settings.json need a restart.
- The agent bypassed task-first 3 times this session despite having the rules. Trust the hook, not the agent.

## Suggested First Action

1. Run `fw context init` then test the PreToolUse hook: try to Edit a file WITHOUT setting focus — it should block with exit 2. If it works, the enforcement is live.
2. If it works, try `fw work-on T-067` and start the plugin onboarding audit task.

## Files Changed This Session

- Created: `agents/context/check-active-task.sh`, `.claude/commands/start-work.md`
- Modified: `CLAUDE.md` (instruction precedence, session start protocol, quick reference), `FRAMEWORK.md` (working with tasks), `bin/fw` (work-on command), `.claude/settings.json` (PreToolUse hook), `011-EnforcementConfig.md` (implementation status), `.context/project/gaps.yaml` (G-001 decided-build), `web/blueprints/timeline.py` (task names + narrative truncation), `web/templates/timeline.html` (inline descriptions)
- Playwright config: `/root/.claude/plugins/cache/claude-plugins-official/playwright/2cd88e7947b7/.mcp.json` and marketplace copy (--no-sandbox)

## Recent Commits
