安装

3. `cd ~/.dsh/profiles/web && pnpm install`
4. Restart DSH web. Open **Settings → 📊 Token Stats**.

> `cordis.patch.yml` declares the bundle-layer mount point so the plugin auto-loads at startup.

## How it works

- **Authoritative data** = DSH persisted session logs: `assistant/message` events carry real `usage`
  (input / output / cache-read / cache-write / reasoning tokens), `request/header` events carry provider/model.
- A one-shot backfill at startup (`sessionQuery`) rebuilds the in-memory aggregation index from all history
  (bounded concurrency).
- `llm/stream` usage chunks are captured for live (display-only) in-flight totals.
- When an adapter reports no usage, `tokenMeter.estimateMessage` is used and the record is flagged `estimated`.

## HTTP API (`/token-stats/api`)

| op | description |
| --- | --- |
| `summary` | today / week / month / total aggregates |
| `query` | time series (day/week/month) + per-model / per-session aggregates; filters: `model`, `sessionId`, `from`, `to` |
| `models` | built-in pricing table (USD per 1M tokens) + USD→CNY rate |
| `sessions` | session list (`id` + `title`) |
| `export` | CSV / JSON dump (`format=csv\|json`, optional `model` / `sessionId`) |
