v0.31: Make vibe-coded software prove it can fail

Code Factory v0.31 is for the moment after an AI coding tool says “done.”

For vibe coding, it helps turn a prompt or PRD into a contained local MVP, then checks whether the evidence can actually reject a bad result. The new `factory e2e verify` gate requires a passing path and a deliberately broken path. If the broken path still passes, it reports `HOLLOW_E2E_TEST`—a test that ran without proving anything useful.

For teams, it adds a practical operating layer around AI-assisted changes:

• Plan-to-Proof compares the real diff with a human-approved plan and records scope, test, and evidence gaps as Proof Debt.

• Proof Review binds review artifacts to the exact PR head, so reviewers can inspect what changed and what was actually checked.

• Team Pilot prepares an owner-reviewed packet covering deployment, security, retention, support, and commercial boundaries for 1–3 design partners.

It is local-first and vendor-independent: use it alongside Codex, Claude Code, Copilot, CodeRabbit, or another assistant. Suggestions remain suggestions; evidence is explicit; merge, release, credential, and customer decisions stay human-owned.
