## Usage Monitor (MAN-21)
Built live dashboard at `heartbeats/monitor/monitor.html`. Client-side JS fetches `sessions.jsonl`, 3 drillable dimensions (channel/domain/model), cost/tokens/sessions toggle, SVG charts. Landing page at `channels/web/index.html`.

## Memory & Reflection (MAN-20)
- Renamed state file → `most-recent-reflections.json`, heartbeat dir → `heartbeats/heartbeats/`
- Dailies now in `last-one-week/`, weeklies in `last-one-month/`
- Added propagation: after each compilation, second ClaudeBridge updates identity files + core-memories
- Core memories = happiness only

## Linear sync fix
Removed git ops from `channels/linear/sync.ts`. Restarted daemon (first attempt failed — old code still in memory).

## Postmortems (5)

**Don't create then cancel.** Created MAN-23 just to cancel it. If something shouldn't be tracked, don't create it.

**Check the system, not memory.** Asked if items were in aceRADAR, answered "no" from memory. They were there. When asked "is X in [system]?" — query the system.

**Trace all consumers.** Deleted check-compliance.csv, grepped code, missed HEARTBEATS.md (a prompt file, not code). When deleting anything, check what reads it — not just what imports it.

**Update the canonical doc.** Changed heartbeat schedule but didn't update MAN-21. Same failure twice. MAN-21 is canonical for heartbeats — any change must include it.

**Check the tool, not your notes.** Asked about Chrome work, searched notes instead of checking Chrome. When asked about work in a specific tool, check that tool first.

## Memory Compaction System (MAN-9)

Restructured memory loading and added automated compaction:

- **Load order:** session-start.sh now loads identity files → core-memories → last-one-week → last-one-month → last-one-year → each-past-year
- **New directory:** `last-one-year/` added (12 monthly files). Monthly compilations now go here; annual compilations go to `each-past-year/`.
- **Per-file compaction added to reflection.ts:** `checkCompaction()` runs after temporal compilations. Any file over its word trigger gets rewritten to its target by Opus, which reads ALL memory files first for full context.
- **ACE.md deduplicated:** Removed 70-line Tasks section that duplicated TASK-MANAGEMENT.md. Replaced with 4-line pointer. Cut ACE.md from 1,841 → 920 words.
- **TOOLS.md tightened:** Removed meta-explanation filler. 389 → 266 words.
- **Total memory footprint:** 6,107 → 4,203 words after Opus review pass.
- **SOUL.md merged into ACE.md** (done earlier in session). Original deleted.
