Three-stage fail-fast validator for LLM-generated bot candidates: - syntax.go: language-aware parse (go/parser for Go; py_compile, rustfmt, tsc, javac, php -l for others; brace-balance fallback) - schema.go: regex detection of /health + /turn endpoints and "moves" field - sandbox.go: nsjail-isolated smoke test — builds bot, polls /health, sends 5 signed /turn requests, verifies JSON moves responses - validator.go: orchestrates stages with fail-fast short-circuit DB layer: - programs table + CRUD (create, get, list, updateFitness, setPromoted) - validation_log table with RecordValidation, IslandPassRates, IslandValidationStats for per-island pass-rate tracking - seed.go: 6 generation-0 bots across alpha/beta/gamma/delta islands MAP-Elites grid (mapelites/grid.go): 2-D behavior grid on aggression×economy axes; TryPlace keeps the fittest occupant per niche. acb-evolver CLI gains two new subcommands: validate <file> -lang <lang> [-island <island>] [-nsjail] [-nolog] validation-stats (tabular per-island pass-rate breakdown) cmd/acb-api/db.go: add programs table to API schema so the API can query promoted evolved bots.
