Converge and polish

Stage contract

• Stage: 5. Build & converge (the engine — orchestrates 5a spawning-reviewers, 5b unvibe-review) · Kind: method
• Inputs: one slice (from stage 4) — or any artifact to harden.
• Outputs: a converged, hardened artifact on a branch, with a per-iteration trail kept beside the work.
• Entry gate: you have one buildable unit; for a multi-slice build, a fresh session per slice.
• Done when (Mode A bar): two consecutive near-zero passes from cross-family critics
  • a final whole-artifact pass, with polish-to-settle after the last destabilizing change. You declare it from the raw findings — never because a reviewer said "looks converged."
• Next: the qa-demo-stand skill — once all slices have converged.
• Maintains: —

One loop, two exit policies. The loop turns reviews and cuts into steady, honest improvement. CONVERGE mode runs it until the artifact stops yielding real findings, then stops. ENDLESS mode never stops on its own — it rotates across a project and exits only on an explicit human signal.
