It does not prove that every detected interface is enabled, reachable, secure, or operational in the deployed environment. ## Pre-upgrade gate - Previous release path and rollback command are known and tested. - Database/configuration migrations are identified, backed up and reversible or explicitly irreversible. - External interfaces and dependent modules have compatibility expectations recorded. - A maintenance/communications plan exists for user-visible interruption. - Acceptance tests and responsible reviewer are assigned. ## Upgrade sequence ```text backup → stage new release → install/validate dependencies → migrate if required → switch active release → restart affected services → smoke/acceptance tests → observe → approve or roll back ``` ## Rollback sequence ```text stop traffic/affected service → restore compatible data/config if required → repoint active release → restart → validate local/public endpoints → record incident and preserve failed-release evidence ``` ## Release-specific comparison No previous release was supplied. Run with `--compare /path/to/previous-release` to generate a static change inventory. --- ## Maintainer Notes Add human-reviewed deployment notes, corrections, decisions, screenshots, and links here.
