The dominant production failure was a dead dev-server process behind a 'running' DB flag (idle-stop / OOM / crash / host restart), which the UI trusted and embedded -> permanent 502 until a manual restart. - dev-container.ts: add isDevServerListening() fast liveness probe; stop the container entrypoint from auto-running 'npx next dev --webpack' (it competed with the managed server, forced the wrong bundler/cwd, and doubled memory); drop the fake state='running' seed row; bump dev container memory 1g -> 2g. - ensure route: verify a 'running' row is ACTUALLY listening and resurrect it if dead, instead of trusting the flag; never bounce a healthy server. - preview page: call ensure on every mount and on refresh (verify + heal), force an immediate anatomy refetch on (re)start so a dead frame swaps to 'warming up' without the 5s lag. Backstopped by the partial unique index + startDevServer idempotency, so heals can never duplicate or thrash a server.
