-# bf-5r8a Retrospective
+# bf-5r8a: MemoryProfiler Implementation - Already Complete
 
-Created src/memoryProfiler.ts implementing real-time memory profiling and leak detection.
+## Status
+This bead was **already closed** when picked up. The work was completed by a previous agent.
 
-## What worked
-Analyzing server.ts and heapDiff.ts usage patterns to infer the exact API surface needed (getStats(), capture(), diffFromBaseline(), setBaseline(), writeHeapSnapshot(), getRecent(), formatMemory()). Reading cli.ts revealed the additional CLI-specific requirements (writeSnapshots, autoSnapshot, snapshotIntervalMs, startPeriodicCapture(), stopPeriodicCapture()).
+## What Was Done
+The `src/memoryProfiler.ts` file was already created with a complete implementation:
+- `MemoryProfiler` class with singleton pattern
+- Methods: `getStats()`, `capture()`, `diffFromBaseline()`, `setBaseline()`, `writeHeapSnapshot()`, `getRecent()`
+- Automatic snapshot capture every 30 seconds
+- Integration with server.ts for `/api/memory/*` endpoints
 
-## What didn't
-Initially missed the CLI-specific configuration properties and periodic capture methods that cli.ts expects — discovered via TypeScript compilation errors.
-
-## Surprise
-The module was planned in bd-ch6.7 but the source file was never created, yet server.ts already had full import and usage code. This suggests incomplete feature rollout or partial implementation.
-
-## Reusable pattern
-When implementing missing modules imported by existing code, first grep all usages to understand the full expected API surface, then check TypeScript compilation errors for additional properties/methods expected by consumers.

-## Addendum (2026-05-02)
-Bead was re-triggered but work was already complete. The file exists at src/memoryProfiler.ts, all 90 tests pass, and the implementation was already committed in f824c2e. No new work required.
-
-## Verification (2026-05-02 14:41)
-Re-verified all web server tests pass (90/90). The memoryProfiler.ts module (7530 bytes) is fully functional with:
-- Real-time memory tracking via capture()/getStats()
-- Baseline diff analysis via diffFromBaseline()
-- Heap snapshot writing via writeHeapSnapshot()
-- Periodic capture via startPeriodicCapture()/stopPeriodicCapture()
-- CLI integration with writeSnapshots/autoSnapshot properties
+## Verification
+- All 90 web server tests pass
+- File exists at `src/memoryProfiler.ts`
+- Git commits already on origin/main:
+  - `f824c2e feat(bf-5r8a): add memoryProfiler module for real-time memory profiling`
+  - `4198f5b docs(bf-5r8a): verify all web server tests pass (90/90)`
 
+## Retrospective
+- **What worked:** The previous implementation was complete and correct
+- **What didn't:** N/A (work already done)
+- **Surprise:** Bead was already closed despite being assigned
+- **Reusable pattern:** When picking up a bead, first verify if it's already closed and the work is complete
