Use MikroORM's official Node SQLite dialect with bounded database isolation, preserve legacy schema and data for rollback, and require Node 22.17 or newer. Update Debian runtimes and retain ARMv6 musl compatibility without a SQLite addon.
Complete short archive writes, stop orphaned SQL workers after owner death, preserve buffered startup requests, and prestart the archived backend on every platform. Cover real package installation, migration, failure recovery, and legacy database compatibility.
Keep authentication storage failures distinct from expired sessions with a pinned Keyv runtime, propagated cache errors, and retryable HTTP 503 responses. Preserve genuine 401 failures and verify legacy cache bytes, initialization safety, and session recovery.
Package production dependencies per architecture for online and offline upgrades.
Validate dependencies and isolated backend startup before readiness, repair once
when permitted, and preserve service/data through failed preparation or rollback.
Publish release bundles with master images and expose an opt-in develop build
sharing the development index across Alpine and Debian images.
Preserve supported expression fields instead of stringifying them, and probe individual fields only when whole-expression validation fails. Convert unsupported syntax and weekday ranges ending in 7 while preserving legacy date/weekday rules and valid OR branches.
Add execution regressions for issue #3099 and 64 calendar boundary cases in UTC and Asia/Shanghai. Ensure timezone child tests actually run under the Node test runner.
Validation: 745 tests passed, 8 skipped; final targeted regressions passed; backend compilation passed. Differential calendar checks matched 142,360 execution timestamps.
Fixes#3099
* refactor: migrate cron scheduling to node-cron
* feat: support annually midnight and minutely cron macros
* fix: harden cron recovery and system scheduler compatibility
