docs(bf-48nk): document genesis bead resolution 
The bead description claimed missing modules and features, but investigation
showed all implementation gaps were already closed. Test failures were due
to better-sqlite3 native module version mismatch (NODE_MODULE_VERSION 115
vs 137), resolved by rebuilding the module.

All 2484 tests now pass (4 skipped). No source code changes were needed.

Raw Blame History

Bead bf-48nk Resolution

Issue Reported

The genesis bead bf-48nk claimed:

  1. Missing module: src/memoryProfiler.ts
  2. Web frontend: treemap + timelapse in FileHeatmap not implemented
  3. Web frontend: SpanDag zoom/pan interaction not implemented
  4. 89 failing unit tests across 10 test files

Investigation Findings

All claimed implementation gaps were already closed:

  • src/memoryProfiler.ts exists (7530 bytes, implemented 2025-05-02)
  • FileHeatmap tests pass (31 tests including treemap + timelapse)
  • SpanDag tests pass (35 tests including zoom/pan)

Root Cause

The 397 test failures were caused by better-sqlite3 native module version mismatch:

  • Module compiled for NODE_MODULE_VERSION 115
  • Current Node.js requires NODE_MODULE_VERSION 137

Resolution

Rebuilt native module: npm rebuild better-sqlite3

Result

All 2484 tests pass (4 skipped).

Retrospective

The bead description was based on stale information. Prior agent runs had already completed all actual implementation work. This run only:

  1. Diagnosed the native module mismatch
  2. Rebuilt better-sqlite3
  3. Verified all tests pass

No source code changes were needed.
