- GET /api/metrics renders Prometheus text (equity, P&L, per-strategy equity/pnl/allocation/halted, info) with no client library. - In-memory ring log handler (app/logs.py) exposed at GET /api/logs and a dashboard "Server logs" panel; Runtime mirrors bot events into the logger. - docs/runbook.md covers deploys, the kill switch, resetting paper state and going live. Adds tests for metrics rendering and the log ring.
