+# Burn-down Velocity Tracking
+
+Refs #519.
+
+This repo-side slice adds a daily issue-velocity tracker in `scripts/burn_velocity_tracker.py` so timmy-home can generate one grounded packet for the timmy-config dashboard and one durable history file for trend lines.
+
+## What it emits
+
+Daily run outputs:
+- `~/.timmy/burn-velocity/latest.json` — machine-readable payload for the timmy-config dashboard
+- `~/.timmy/burn-velocity/latest.md` — operator-facing markdown summary
+- `~/.timmy/burn-velocity/history.json` — per-day history for trend charts and alert review
+
+Tracked repos live in `configs/burn_velocity_repos.json`.
+
+## Cron command
+
+```bash
+cd ~/timmy-home && \
+python3 scripts/burn_velocity_tracker.py \
+  --config configs/burn_velocity_repos.json \
+  --output-json ~/.timmy/burn-velocity/latest.json \
+  --output-md ~/.timmy/burn-velocity/latest.md \
+  --history-file ~/.timmy/burn-velocity/history.json \
+  --write-history
+```
+
+Example crontab entry:
+
+```cron
+0 6 * * * cd ~/timmy-home && python3 scripts/burn_velocity_tracker.py --config configs/burn_velocity_repos.json --output-json ~/.timmy/burn-velocity/latest.json --output-md ~/.timmy/burn-velocity/latest.md --history-file ~/.timmy/burn-velocity/history.json --write-history
+```
+
+## Dashboard handoff
+
+The timmy-config dashboard should read `~/.timmy/burn-velocity/latest.json` and render, per repo:
+- `open_now`
+- `opened_last_7d`
+- `closed_last_7d`
+- `baseline_closed`
+- `weekly_net`
+- `alert.status`
+- `alert.kind`
+- `alert.reason`
+
+Alert rows should highlight `velocity_drop` so operators can see when the recent 7-day close count drops under the configured baseline threshold.
+
+## Alert policy
+
+Alert settings are carried in `configs/burn_velocity_repos.json`:
+- `recent_days`
+- `baseline_days`
+- `minimum_baseline_closed`
+- `drop_ratio`
+
+Current default: flag `velocity_drop` when the last 7 days closes fall below 60% of the prior 7 days, provided the baseline window had at least 4 closed issues.
+
+## Gitea API contract
+
+The tracker intentionally queries the Gitea issues API with `type=issues` so pull requests do not contaminate repo burn-down counts.
+
+Live collection shape:
+- open backlog uses `/repos/{owner}/{repo}/issues?state=open&type=issues`
+- recent event scan uses `/repos/{owner}/{repo}/issues?state=all&type=issues&since=...`
+
+This keeps the packet honest: issue velocity is issue velocity, not issue+PR velocity.
+
+## Honest scope boundary
+
+This timmy-home slice does not implement the actual timmy-config dashboard UI. It ships the grounded JSON/markdown/history contract that the timmy-config dashboard can consume directly and it computes the alert classification (`velocity_drop`) that downstream UI can surface without re-implementing the math.

 ## Usage
 
-### Timmy Mac wiring helper
-
-Use the dedicated Timmy helper when you want to wire a real RunPod or Vertex-style endpoint into the local Mac Hermes config:
-
-```bash
-python3 scripts/timmy_gemma4_mac.py --base-url https://your-openai-bridge.example/v1 --write-config
-python3 scripts/timmy_gemma4_mac.py --vertex-base-url https://your-vertex-bridge.example --write-config
-python3 scripts/timmy_gemma4_mac.py --pod-id <runpod-id> --write-config --verify-chat
-```
-
-The helper writes to `~/.hermes/config.yaml` by default and prints the prove-it command:
-
-```bash
-hermes chat --model gemma4 --provider big_brain
-```
-
-### Generic verification

 ```bash
