Mantyl is built with itself. Every release below was verified by its own passport before it shipped, and several of the fixes came from findings the tool surfaced about its own repository.

The CLI is publicly installable with npm install -g mantyl, a single self-contained package with one dependency. mantyl publish hosts an approved passport at a shareable link derived from its digest, free during alpha, with the server independently rechecking schema and digest before hosting anything. Hosted passports are live in production. The site gained real documentation and this changelog.

Passports now carry the decision log: choices recovered from agent history, with the creator's own recorded words marked as creator confirmed. The whole loop passes on Mantyl's own repository: five sandbox checks pass, the passport generates, and receive independently reproduces every check with no divergence.

Verification runs in one persistent container per project, with network connected for install and then cut. Running Mantyl on itself caught four sandbox defects and one real repository defect: the site fetched fonts at build time, which would have broken any recipient building offline. The fonts are now vendored.

Optional analysis writes an architecture narrative and risk list from redacted evidence. Everything it produces is permanently marked as inference, schema validated locally, and the pipeline stays complete without it.

Scan, verify, generate and receive, end to end. Deterministic scanning with fail-closed secret redaction, Docker sandbox verification, the eight-status truth model, contradiction detection, content-addressed integrity digests and the recipient's independent verdict.
