Post one scoped software task. Three hand-picked builders send sealed, fixed-price quotes with ETA, assumptions, and exclusions. You authorize a card hold when you pick one; it is captured only after signoff.
Plain prose is fine. During the pilot, every job is reviewed before it goes to builders so vague scope gets tightened before bids arrive.
Hand-picked operators who already run Claude Code or Codex as part of their stack. You get three sealed, normalized quotes back: price, ETA, what they're assuming, what they're not doing.
The accepted bid plus buyer fee becomes a card hold. It is captured on completion, released on cancellation, and kept authorized during one rework round.
AI code generators are great at prototypes. They are not great at security, deployment, or edge cases. A bidflock builder can harden what you already have for a fixed price — no "it depends", no hourly guessing.
No names, no bid amounts across sellers. The ledger is public by design — you should be able to see the loop work before you post.
