Read `../../references/release-and-compliance.md` and `../../references/testing-and-evidence.md`. Determine actual target (preview, staging, production, TestFlight, App Store, Play Console, distributable ZIP).\n2. Confirm app identifier, version, environments, signing, legal/privacy copy, runtime secrets, data retention, content policy and platform permissions. Do not invent organization identities, privacy policies or store screenshots.\n3. Run available build/test/security/accessibility checks and attach evidence. Provide platform-specific blockers (macOS/Xcode for Apple signing, keystore/Android build tools for Android, HTTPS for PWAs, DNS for web).\n4. Prepare deployment checklist, release notes, rollback/backup strategy and known issues. Ask for user approval before deploy, public sharing, purchases, external writes or app-store submission.\n5. Return a verified release bundle where tools support it; otherwise a clearly labeled release-readiness report, not a false publication claim.\n"
