Dark Fulcrum Force

Dark Fulcrum Force is our tablekeeper entry for the WeAreDevelopers × BAND Dark Factory hackathon: an autonomous "factory" of six coding agents that turns one operator dispatch into shipped, verified software with no human in the loop afterward. The band has six seats, each with one job and a generic mandate that carries no track-specific details — the specifics live only in the dispatch, so the same mandates work on any project. FORGE plans the work and issues sealed handoff packets; each packet's hash covers the spec, base revision, target seat, and a lease built from handoff and attempt numbers, and every receiving seat verifies the seal before acting. HAMMER and ANVIL implement the same stage independently — one in Python, one in Node, on different models — without seeing each other's code. PROBE runs the supplied tests plus its own probes against each build; CONTRA attacks both adversarially; WARDEN keeps the full evidence trail. In the run that produced this submission, the operator created and bound the seats, then posted one dispatch at 9:15 PM Central — the only human message in the room. Review caught a defect in one build; ANVIL's repaired build passed the checks and became the merged base. The result is tablekeeper, a restaurant reservation service built so a table is never double-booked under concurrency, retries, and time zones. It builds and serves from a clean container with no outbound network and passes all 120 shipped Stage 1 checks. Everything — the factory, the mandates, the room recording, and the code — is in the public repo.
