## Description
## Token Usage Monitor for Ace Manglasabang

Dashboard and monitoring channel for tracking all Ace session usage.

### Location

* Channel: `channels/monitor/`
* Dashboard: `channels/monitor/monitor.html`
* Data: `channels/monitor/sessions.jsonl`
* Schedule: daily at 22:00 PST (launchd)

### How It Works

ClaudeBridge auto-logs every session. No per-channel instrumentation needed. When any channel gets a `result` from Claude CLI, bridge.ts parses the usage data and appends to `sessions.jsonl`.

Fields tracked per session: date, time, channel, domain, model, duration_ms, duration_min, tokens_in, tokens_out, cost_usd, num_turns.

### Domain Tracking

* Email: `ace@palace.fund` -> palacefund, `ace@manglasabang.com` -> junwonhome
* Linear: matched from issue labels (junwonhome, junwoncompany, palacefund, palaceapp, palacelab)
* Other channels: no domain (heartbeat, briefing, market-report, slack, monitor)

### Dashboard (monitor.html)

Mobile-friendly dark theme. Three tabs: Today, 7 Days, All Time.

Sections:

* Summary cards: sessions, duration, cost, tokens out
* By Channel (color-coded bars)
* By Model
* By Domain (color-coded bars)
* Daily Trend (sparkline, 7-day/all-time only)
* Recent Sessions (last 15, with channel dot + domain)

Regenerated on each `monitor.ts` run with embedded data.

### Channels Instrumented

All channels set `bridge.channel` and domain where applicable:

* heartbeat (channel only)
* email (channel + domain per account)
* slack (channel only)
* linear (channel + domain per issue labels)
* briefing (channel only)
* market-report (channel only)

### Status

Complete. Service installed and running.
