 - Feishu/Plugins: restore bundled Feishu SDK availability for global installs and strip `openclaw: workspace:*` from plugin `devDependencies` during plugin-version sync so npm-installed Feishu plugins do not fail dependency install. (#23611, #23645, #23603)
 - Plugins/Install: strip `workspace:*` devDependency entries from copied plugin manifests before `npm install --omit=dev`, preventing `EUNSUPPORTEDPROTOCOL` install failures for npm-published channel plugins (including Feishu and MS Teams).
 - Config/Channels: auto-enable built-in channels by writing `channels.<id>.enabled=true` (not `plugins.entries.<id>`), and stop adding built-ins to `plugins.allow`, preventing `plugins.entries.telegram: plugin not found` validation failures.
+- Config/Channels: when `plugins.allow` is active, auto-enable/enable flows now also allowlist configured built-in channels so `channels.<id>.enabled=true` cannot remain blocked by restrictive plugin allowlists.
 - Plugins/Discovery: ignore scanned extension backup/disabled directory patterns (for example `.backup-*`, `.bak`, `.disabled*`) and move updater backup directories under `.openclaw-install-backups`, preventing duplicate plugin-id collisions from archived copies.
 - Dev tooling: prevent `CLAUDE.md` symlink target regressions by excluding CLAUDE symlink sentinels from `oxfmt` and marking them `-text` in `.gitattributes`, so formatter/EOL normalization cannot reintroduce trailing-newline targets. Thanks @vincentkoc.
 - Cron: honor `cron.maxConcurrentRuns` in the timer loop so due jobs can execute up to the configured parallelism instead of always running serially. (#11595) Thanks @Takhoffman.
