mix certitudo (certitudo v0.1.0)

Run tests, capture coverage, and compare against a previous snapshot.

Each run produces an impressio — the current coverage snapshot. If an identical impressio already exists (same fingerprint), it is reused and labelled Deja vu. The snapshot we compare against is the retentio — either the most recent prior run or an explicit --since target.

Output written to .certitudo/<run_id>/:

snapshot.json — the impressio
coverage.coverdata — raw Erlang cover data
diff.prev.json — differentia between retentio and impressio (when available)

mix certitudo --example
mix certitudo --no-color
mix certitudo --label scenario -- --only scenario
mix certitudo --from-coverdata cover/covprobe.coverdata
mix certitudo --no-auto-diff
mix certitudo --since 20260605T190458Z

Pass --no-color to disable ANSI colors in Certitudo's own output. Pass --example to render the bundled demonstration diff with all statuses, without running tests or comparing snapshots.

mix certitudo.inspectio — inspect and prune .certitudo/ artifacts
mix certitudo.lacunae — show uncovered lines
