# Session 253 Prompt

**Continue from Session 252 (2026-03-09).** This session fixed three REVIEW mode replay bar UX bugs, committed as `fe41103` and deployed to Titan.

## What Was Fixed This Session (252)

### Bug 1: Replay bar spanned multiple days (rewind jumped to yesterday)
- **Root cause:** `toggleMode()` in `main.ts:689` called `enterReview(replayState, buffer.getAll())` which included ALL cached events across multiple days (up to 10,000 from the SSE ring buffer catch-up). The replay `rangeStart` was the oldest event in the buffer — often from yesterday — so rewind jumped to `18:36:12` instead of today's first event.
- **Fix:** Filter to today's events before entering review: `buffer.getAll().filter(e => localDateStr(new Date(e.timestamp)) === todayStr)`
- **File:** `services/context-engine/dashboard/src/main.ts` line 689

### Bug 2: Progress bar started at 100% filled (confusing)
- **Root cause:** `enterReview()` in `replay.ts` set `cursor = rangeEnd` and `lastFiredIndex = sorted.length - 1`, meaning all events were marked "already played" and the bar appeared fully filled on entry.
- **Fix:** Changed to `cursor = rangeStart` and `lastFiredIndex = -1`. Bar starts at 0%, press Play to watch events unfold chronologically.
- **File:** `services/context-engine/dashboard/src/timeMachine/replay.ts` lines 62-76

### Bug 3: No drag scrubbing on progress bar
- **Root cause:** Progress bar only had a `click` event handler — no mousedown/mousemove support. Users couldn't drag across the timeline.
- **Fix:** Added `mousedown` + `mousemove` + `mouseup` listeners with `handleScrub()` function. Includes `e.preventDefault()` to prevent text selection during drag. Falls back to click-only for non-review mode.
- **File:** `services/context-engine/dashboard/src/main.ts` lines 516-550

### Tests Added
- 7 new tests in Group 9 "Start at beginning" in `replay.test.ts`:
  - `enterReview progress bar starts at 0%`
  - `play from start fires ALL events including first`
  - `narrow time range: 20 same-creature events in 2 seconds` (the auth gate scenario)
  - `progress bar fills as cursor advances`
  - `togglePlayPause does not wrap when already at start`
  - `after full playthrough, togglePlayPause wraps to start`
  - `seekTo various ratios produces different cursor positions`
- 5 existing tests updated for new cursor-at-start behavior
- Total: **1,808 dashboard tests pass**, up from 1,785

## Context From Sessions 251-252 (Same Day)

### Session 251 fixes (already committed):
- **Timezone mismatch bug** (`ffccb60`) — `fetchDayEvents()` sent naive timestamps (`2026-03-09T00:00:00`) that asyncpg treated as UTC. With IST (+05:30), this created a 5.5-hour gap causing 5,210 phantom "today" events. Fixed with `localTzOffset()` helper that appends `+05:30` to timestamps. 15 tests in `fetchDayTimezone.test.ts`.
- **REVIEW mode count UX** (`f885a8f`) — Hid raw `buffer.size` (internal cache count like 4,790) in REVIEW mode status bar. Now shows event count only when a specific day is selected, otherwise hidden (`-1`).

### How user discovered the replay bar bug:
1. Opened dashboard → saw "Today, Mar 9 · 5,210 events" (phantom count from timezone bug — fixed in 251)
2. After timezone fix, saw "Today · 20 events" (auth gate events from dashboard SSE connection)
3. Switched to REVIEW → progress bar 100% filled, rewind went to 18:36:12 (yesterday's oldest event)
4. Dragging mouse across progress bar did nothing (click-only, all events same creature)
5. User said: "the answer lies in the way the rewind button works" — correctly identified the multi-day buffer issue

## Completed Plans — All Done

### Plan file: `abstract-giggling-swan.md` — DONE (session 249)
Container restart re-extraction storm fix. Two-tier guard in `_extract_entities`. Already implemented and deployed. This plan file can be cleaned up.

### Priority Roadmap (Session 248) — ALL 5 DONE
| # | Priority | Status |
|---|----------|--------|
| 1 | Live E2E verification | DONE |
| 2 | A/B test Nemotron 3 Nano | DONE |
| 3 | GLiNER2 integration | DONE |
| 4 | Chat streaming | DONE |
| 5 | Sprint 9+ briefing | DONE |

### Sprints 1-8 — ALL COMPLETE
All 8 sprints of the critical path are done (Sprint 3 skipped — Omi webhook redundant).

## What's NOT Done — Open Issues

### Next Major Feature (Sprint 9+)
- **MCP Knowledge Graph Memory Server integration** — the next major feature from `docs/GAP-ANALYSIS.md`
  - Location: `MEMORY.md` line 168

### Dashboard UX Bugs (unfixed)
- **Auth gate observer effect** — Dashboard SSE connection generates ~20 basilisk/auth-gate events inflating Today count. Not filtered yet.
  - Location: `MEMORY.md` Open Issues
  - Possible fixes: filter `process === 'auth-gate'` from `countToday()`, mark as `internal: true`, or exclude from SSE stream
- **REVIEW mode day navigation** — Clicking a historical day in navigator sidebar doesn't update the replay bar (still shows today's events). Needs `nav-view-change` event → `enterReview()` wiring.
  - Location: `MEMORY.md` Open Issues
- **`get_event_days` endpoint timezone** — `DATE(timestamp)` uses PostgreSQL session TZ (likely UTC), may disagree with IST day boundaries. Lower priority.
  - Location: `MEMORY.md` line 183
- **Entity context card in synthetic mode** — Entity store empty without token, need synthetic entities.
  - Location: `MEMORY.md` line 188

### Infrastructure Gaps
- **No GPU queue** — `gpu_queue.py` not created. Sequential processing works for now.
  - Location: `MEMORY.md` Open Issues
- **Entity SSE missing** — Dashboard polls `/v1/entities/clustered` every 30s. No real-time push.
  - Location: `MEMORY.md` Open Issues
- **5-min idle disconnect** — Pipecat WebRTC default. Needs investigation.
  - Location: `MEMORY.md` Open Issues

### Housekeeping
- **Design Execution Engine** — Browser + voice + desktop API channels (backlog)
  - Location: `MEMORY.md` line 210
- **Clean up `abstract-giggling-swan.md`** — Plan file for completed session 249 fix, can be archived
- **Untracked file `phase-d-snapshot.md`** — Sitting in repo root, not committed

## Deployment State

### What's running on Titan:
| Component | Port | Status |
|-----------|------|--------|
| postgres | 5432 | Running |
| context-engine | 8100 | Running |
| audio-pipeline | 9100 | Running |
| ollama | 11434 | Running |
| llama-server | 8003 | Running (Qwen3.5-9B) |
| searxng | 8888 | Running |
| annie-voice | 7860 | Needs verification |
| dashboard (Vite) | 5174 | Running (HMR auto-updated) |

### Git state:
- Local (physical-ai-lab): `fe41103` on `main`
- Titan: `fe41103` on `main` (pulled and deployed)
- Remote (GitHub): `fe41103` on `main`

## Verification To Do First

1. Open dashboard at `http://localhost:5174/?token=bUFUGVI9n_vxO-mnWBF4lamWg9PjmE3Qs4I8NgmCDj0`
2. Switch to REVIEW mode → confirm bar starts at 0% (not 100%)
3. Press Rewind → confirm timestamp is today's first event (not yesterday's 18:36:12)
4. Press Play → watch events unfold chronologically
5. Test drag scrubbing: hold mouse button on progress bar and drag left/right
6. Check Today event count — should show auth gate events (~20) but no phantom thousands
