jedarden 467a4601fd docs(bf-48nk): close genesis bead - all gaps already implemented 
Verified all claimed implementation gaps were already complete:
- src/memoryProfiler.ts exists and works (7530 bytes)
- FileHeatmap treemap + timelapse fully implemented
- SpanDag zoom/pan fully implemented
- All 2399 tests passing (4 skipped, 0 failed)

This was a retrospective tracking bead for work completed
in previous commits (f824c2e, ae4c12c, 6237010).

Bead bf-48nk: FABRIC Implementation Gap Closure

Status: Already Complete - Test Fix Only

The bead description claimed significant implementation gaps in FABRIC, but upon investigation all mentioned features were already fully implemented. This was a retrospective bead for work already complete.

What Was Found

Claimed Gaps (All Already Implemented)

  1. Missing module: src/memoryProfiler.ts

    • Reality: File exists and is fully implemented (7530 bytes)
    • Already completed in commit f824c2e on 2026-05-02
    • See notes/bf-5r8a.md for full details

  2. Web frontend: treemap + timelapse in FileHeatmap not implemented

    • Reality: Both features fully implemented in src/web/frontend/src/components/FileHeatmap.tsx
    • Treemap view: lines 443-524 (calculateTreemapLayout function)
    • Timelapse view: lines 526-641 (playback controls, speed, slider, loop)

  3. Web frontend: SpanDag zoom/pan interaction not implemented

    • Reality: Fully implemented in src/web/frontend/src/components/SpanDag.tsx
    • Zoom controls: lines 231-259
    • Pan functionality: lines 180-206
    • All 13 SpanDag zoom/pan tests passing

  4. Bug fixes: 89 failing unit tests

    • Reality: Only 1 failing test out of 2403 total
    • The failure was a test selector bug, not implementation gap

Actual Work Done

Fixed one failing test:

  • File: src/web/frontend/test/FileHeatmap.test.tsx
  • Issue: Test selector .timelapse-playback button.primary expected button to have "primary" class
  • Fix: Changed to .timelapse-playback button to find button regardless of play state
  • Root cause: Button only has "primary" class when isPlaying=true, initially false

Final Test Results

  • 65 test files passed
  • 2399 tests passed
  • 4 skipped
  • 0 failed

Bead Closure

Bead bf-48nk closed on 2026-05-02. All claimed gaps were verified as already implemented in previous work.

Retrospective

  • What worked: The investigation approach — running tests first, then checking specific files mentioned in gaps — efficiently revealed all gaps were already closed.
  • What didn't: The bead description was based on outdated information; no actual implementation work was needed.
  • Surprise: The genesis bead tracked work completed days earlier; this highlights the importance of validating gap claims before starting implementation.
  • Reusable pattern: For gap closure tasks, always run the full test suite first — passing tests immediately invalidate implementation gap claims.
