The builder could only create games; nothing noticed when a live template stopped working, and there was no way to tell whether a builder change made it better or worse. - repair -id ID: boots an existing template as nodes run it; if it fails, the same investigation as for a draft runs and the model changes only what the diagnosis says. The worker handles "repair" jobs (gameId from the panel) and opens "fix(games): repair ..." on draft/<id>; a template that boots as it is reports "nothing to repair" and opens no PR. The boot and fix loop is now shared by builds and repairs. - validate.yml runs weekly and boot-tests every game; failed games are sent to the panel (X-GBR-Event: games_boot_failed) to queue repairs. - eval -ids all: builds games that already have a template from scratch, blind, and scores each draft against it (boots, same image and app, ports, ready line, settings found) into eval.md and eval.json. - research skips our own sites, so neither research nor eval reads our templates back.
