# bf-48nk: FABRIC implementation gap closure

## Issue Summary
The genesis bead indicated 89 failing unit tests across 10 test files, with missing module `src/memoryProfiler.ts` and unimplemented features.

## Root Cause
All test failures were due to a native module version mismatch. The `better-sqlite3` module was compiled against Node.js NODE_MODULE_VERSION 137 but the runtime required NODE_MODULE_VERSION 127.

## Resolution
Rebuilt the native module:
```bash
npm rebuild better-sqlite3
```

After the rebuild:
- All 2484 tests passed (4 skipped)
- src/memoryProfiler.ts was already present and complete
- No code changes were needed

## Verification
```bash
npm test
# Test Files  68 passed (68)
# Tests       2484 passed (2488)
```
