Add the secondary-persona path from docs/BROWSER-ROTATION.md: ingest a password manager / browser store, take a mandatory verified sealed backup, generate fresh strong passwords, hand the human a ready-to-finish task at the MFA wall, and commit the new value into the manager only after the site change is confirmed. - internal/pwgen: crypto/rand generator (rejection sampling, per-class guarantee, vault-native — never returns plaintext as a Go string). - internal/pwstore: Manager/ItemUpdater/BulkImporter contracts, secrets-free RedactIdentity, and five adapters — bitwarden (bw, stdin), keepassxc (keepassxc-cli, stdin), 1password (op, argv assignment with documented caveat), chrome/firefox (tmpfs CSV ingest-and-shred). All real code; validation status is data (MOCK-ONLY against fake binaries/CSVs, recorded in the design doc). - internal/pwstore/stage.go: age-sealed staged-list (WriteStaged/ReadStaged) + StagedImporter — the only artifacts crossing the plan->commit gap, never plaintext. - cmd/incredigo: passwords scan|plan|guide|commit. Backup gate seals + round-trip verifies before any commit; guide is interactive verify-before-commit; commit is headless over a sealed stage. Browser CSV writes are gated behind --allow-csv. Hard rules honored: backup-before-commit, verify-before-commit, no plaintext on disk (browser CSV is the flag-gated tmpfs+shred exception), MFA always a human handoff. go vet + -race clean; end-to-end verified against a fake bw.
