# Session Handover: S-2026-0221-1420

## Where We Are

Fixed the fabric page "flicker" — root cause was subsystem cards linking to themselves (same page with filter param). Cards now collapse to a focused header when filtered. Also fixed broken dropdown filters (wrong param names). T-227 completed. User wants to investigate enforcement bypass strengthening next session.

## Work in Progress

<!-- horizon: now -->

### T-200: "Discovery layer design — pattern detection, omission finding, insight surfacing (T-194 Phase 4)"
- **Status:** captured (horizon: now)
- **Last action:** Untouched this session
- **Next step:** Begin inception exploration
- **Blockers:** None
- **Insight:** None

### T-220: "Fabric component detail — inline source code viewer"
- **Status:** started-work (horizon: now)
- **Last action:** Source viewer implemented (7ed0b1d), body-level htmx defaults added to base.html
- **Next step:** Human ACs pending (dark theme contrast, collapsible section UX)
- **Blockers:** Waiting for human verification
- **Insight:** None

### T-227: "Fix fabric page — subsystem cards link to themselves, dropdown filters broken"
- **Status:** work-completed (horizon: now)
- **Last action:** Fixed both bugs — subsystem cards collapse when filtered, dropdown param names aligned
- **Next step:** Human AC pending (filtered view visual quality)
- **Blockers:** None
- **Insight:** The "flicker" was a UX issue, not JS — 12 cards reloaded identically because they linked to the same page. Dropdown filters were also silently broken (name mismatch)

## Inception Phases

**1 inception task(s) pending decision** — run `fw inception status` for details.

## Gaps Register

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

- **G-004** [low]: Multi-agent collaboration untested

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

## Decisions Made This Session

1. **Collapse subsystem cards when filtered instead of removing hx-boost**
   - Why: The "flicker" was a UX problem (self-linking cards), not an htmx issue
   - Alternatives rejected: Removing hx-boost (would break ~20 bare links), adding JS debounce (wrong diagnosis)

## Things Tried That Failed

1. **Previous sessions: htmx body-level defaults** — added `hx-target="#content" hx-swap="innerHTML"` to body tag. Didn't fix the flicker because the root cause was UX (cards linking to themselves), not htmx targeting.
2. **Previous sessions: Playwright network monitoring** — could not reproduce flicker in headless Chromium because the "flicker" was visual sameness, not a double request.

## Open Questions / Blockers

1. User wants to investigate how framework enforcement rules could be bypassed and how to strengthen them — create inception task next session

## Gotchas / Warnings for Next Session

- Flask template caching: after editing templates, server restart may be needed to pick up changes
- Pipe in curl verification commands causes SIGPIPE (exit 23) — use `-o file && grep file` pattern instead

## Suggested First Action

Investigate enforcement bypass per user request — check hook configuration, gate scripts, identify gaps. Consider creating an inception task for this.

## Files Changed This Session

- Modified: `web/templates/fabric.html` (subsystem cards collapse + dropdown name fix)
- Modified: `web/templates/base.html` (body-level htmx defaults from prior session, committed this session)
