CAT Dark Factory

Use these exact entries. Submission Title CAT Dark Factory Short Description An autonomous software factory that separates implementation, evidence, and acceptance. CAT uses independent agents, deterministic contract gates, durable handoffs, and reviewer-driven repair loops so software is accepted by evidence—not by its author. Long Description `CAT Dark Factory is an autonomous software-delivery system designed around one principle: the agent that writes software should not be the agent that decides whether it is correct. For the Pocketful challenge, CAT R4 used four independent roles: Coordinator, Implementer, Evidence Engineer, and Reviewer. After a single human dispatch, the factory operated autonomously. The Implementer produced committed candidate revisions, deterministic contract checks validated each candidate, the Evidence Engineer generated independent evidence, and the Reviewer made the final acceptance decision. Failed reviews were automatically converted into evidence-backed repair requests and routed back to the Implementer. This was not a simulated workflow. Stage 1 required six implementation attempts before acceptance. The factory caught issues including idempotency and state round-trip edge cases, malformed split participant types, and settlement authorization precedence. CAT also demonstrated recovery from infrastructure failure. When an Evidence Engineer process timed out, the factory recovered an already-prepared durable handoff without another human task message and without creating a duplicate logical handoff. The final accepted Stage 1 revision was published publicly and independently validated from a fresh clone. The official isolated harness collected 147 tests: 147 passed, with zero failures and zero errors. CAT combines SHA-bound handoffs, durable orchestration state, deterministic gates, independent evidence, independent review, auditable Git history, and autonomous repair loops. Its goal is not simply to make agents write more code.
