OpenMainty is a local maintainer tool for open source. It watches repositories for dependency drift and open issues/PRs/Discussions, verifies updates in a sandbox on the owner's Mac, and prepares reviewable batches and PR drafts. It never pushes; a human merges.

Problem: small open-source repos rot between releases. Dependency bumps pile up unreviewed, lockfiles drift from manifests, and checking one bump costs a full install/test/build cycle that solo maintainers don't have time for.

Solution: watch -> review -> prepare -> sandboxed fast check -> batch -> human approval -> PR draft, with evidence recorded and honest stops wherever a human decision is needed. A local web dashboard (at-a-glance decisions, control center, runs, daily digest, per-repo dependencies/PRs/Discussions, relation graph) shows what needs the maintainer.

Verified state: 32 independently gated promotions (latest app 75ab15721af543f8); 127 test modules / 3,672 tests pass on Python 3.14 and 3.9; the dashboard was checked in a real browser at 1280px and 390px, light and dark; live tracking of my own repos (react-native-nitro-sound, flutter_calendar_carousel) matches GitHub.

How it was built: Muse Code (Muse Spark 1.3) wrote the code, tests and docs; a separate supervisor only reviewed, ran isolated independent tests and real-browser checks, and kept failed checks on record.

Limits (honest): one real maintenance case run end to end and the worker-binding proof are still in progress. No claims of resolving every issue or of unverified native behaviour.
