The agent that built it prepares the handover.
The evidence of an AI-assisted build lives in the session that produced it. The Mantyl plugin puts the passport loop inside Claude Code, so finishing a build session and preparing its proof become the same motion.
The honest loop
Doctor first, then the full pipeline: checks executed in your local Docker, the passport generated, and the findings reported in a fixed order with contradictions first, never softened. If something traces to the session’s own work, the agent offers to fix it and re-run.
Your call, always
It never publishes and never buys verification on its own: hosting the passport and the £29 signed run are offered as your choices at the end, and hand edits to passport artefacts are refused because digests turn them into tamper evidence.
Requires the free CLI (Node 20+, git, Docker for executed checks) and Claude Code. The plugin is MIT licensed like everything that runs on your machine, and reads the same truth model the rest of the product lives by.
