Version Integrity & Distribution

Official release notes & verified distribution.

Every production release is cryptographically hashed, signed, and validated against non-destructive database migration standards. Routine upgrades preserve all client records, prescriptions, and financial ledgers.

Non-Destructive Schema Commitment: All published binaries adhere to strictly additive SQLite schema evolution. Running an update binary automatically inspects the local catalog, executes additive column migrations inside an atomic transaction, and creates a pre-upgrade snapshot before applying changes.
