# Session Handover: S-2026-0216-2239

## Where We Are

Watchtower inception UI is live. Three new pages (`/inception`, `/inception/<task_id>`, `/assumptions`) provide full read-only visibility into inception workflows and assumption tracking. The inception phase was dogfooded — used `fw inception start` to create T-084, registered 4 assumptions, decided GO, then built T-085. All 4 assumptions validated with evidence. Audit: 18 PASS, 0 FAIL. Zero active tasks.

## Work Completed This Session

### T-084: Inception — Watchtower inception UI integration (inception, GO)
- Explored Watchtower architecture: Flask + Pico CSS + HTMX, 8 blueprints, fragment templates
- Analyzed inception CLI data models and UI requirements
- Registered 4 assumptions (A-001 through A-004), all validated
- Decided GO: blueprint pattern works, direct YAML reads sufficient, no new dependencies

### T-085: Build Watchtower inception UI pages (build)
- Created `web/blueprints/inception.py` with 3 routes and filtering support
- Created `inception.html` — summary stats, decision badges, assumption progress bars
- Created `inception_detail.html` — problem statement, linked assumptions, criteria, decision record
- Created `assumptions.html` — registry table with status badges, evidence, task links
- Integrated into navigation (Work group) and registered blueprint in app.py
- Added inception to allowed workflow types in task creation API
- Both episodic skeletons enriched

## 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. **Dogfood inception to build inception UI** — Used `fw inception start` and assumptions workflow to validate approach before building. Proved the workflow works for real design decisions.
   - Alternatives rejected: Jump straight to building without inception (misses validation opportunity)

2. **Read-only UI first, write actions later** — Scoped to read-only views of inception tasks and assumptions. Write actions (create/validate from UI) deferred to Phase 2.
   - Alternatives rejected: Build full CRUD immediately (too large, more risk)

3. **Direct YAML parsing in Flask, not CLI intermediary** — Blueprint reads `.context/project/assumptions.yaml` and task frontmatter directly instead of invoking `fw` CLI.
   - Alternatives rejected: Shell out to `fw inception status` (slower, parsing text output is fragile)

4. **Separate nav entries for Inception and Assumptions** — Both appear in Work group rather than nesting assumptions under inception.
   - Alternatives rejected: Single "Inception" entry with sub-tabs (assumptions are cross-inception, deserve own page)

## Things Tried That Failed

No failed approaches this session — architecture exploration was thorough before building.

## Open Questions / Blockers

1. G-005 graduation pipeline trigger still firing (20+ learnings) — should `fw promote` be built? (Carried forward)
2. Phase 2 inception UI write actions — create inception from UI, validate/invalidate assumptions from UI, record decisions from UI
3. Markdown rendering in inception detail sections — currently showing raw markdown text, could use markdown2 for HTML rendering

## Gotchas / Warnings for Next Session

- Web server must be started with `python3 -m web.app` from framework root (not `python3 web/app.py`)
- Inception detail `_extract_decision()` looks for `**Decision**:` pattern — if template format changes, parser breaks
- Assumption task links go to `/inception/<task_id>` which 404s if the linked task is not workflow_type=inception
- Playwright sandbox still fails as root (carried forward)

## Suggested First Action

1. `fw context init`
2. Consider Phase 2: inception write actions from UI (create task, validate assumption via buttons)
3. Or tackle G-005 graduation pipeline (`fw promote`)
4. Or address markdown rendering in inception detail (quick win with markdown2)

## Files Changed This Session

- Created: `web/blueprints/inception.py` (inception blueprint — 3 routes)
- Created: `web/templates/inception.html` (inception list page)
- Created: `web/templates/inception_detail.html` (inception detail page)
- Created: `web/templates/assumptions.html` (assumptions registry page)
- Modified: `web/app.py` (register inception blueprint)
- Modified: `web/shared.py` (add Inception + Assumptions to Work nav)
- Modified: `web/blueprints/tasks.py` (add inception to allowed types)
- Modified: `.context/project/assumptions.yaml` (4 assumptions registered + validated)
- Enriched: `.context/episodic/T-084.yaml`, `.context/episodic/T-085.yaml`
