+## Balance Lab server Python preflight (2026-09-16)
+
+- The production failure was a deployment mismatch: the TrueNAS app used the
+  canonical Node-only startup command even though server Balance Lab jobs need
+  the Python controller. The canonical YAML in both `DEPLOYMENT.md` and the
+  release-runbook appendix now installs `python3`, prints its version during
+  startup, sets `BALANCE_LAB_PYTHON=python3`, and includes the queue limits.
+- A GM-authenticated runtime endpoint now probes the configured executable with
+  `--version`. The Balance Lab setup shows the resolved Python 3 version, and a
+  missing runtime disables **Run on server**. POST requests independently
+  repeat the preflight and return a dedicated 503 without creating a failed job.
+- Nine focused Balance Lab service tests plus two server integration tests, the
+  8 GB TypeScript check, and the production Vite build passed. Production Edge
+  displayed `Server runtime ready · Python 3.14.0`, submitted a real Eck run,
+  generated all reports, and completed desktop/mobile QA without browser errors.
