-- CI/Windows: shard the Windows `checks-windows` test lane into two matrix jobs and honor explicit shard index overrides in `scripts/test-parallel.mjs` to reduce CI critical-path wall time. (#27234) Thanks @joshavant.
 - Docker/GCP onboarding: reduce first-build OOM risk by capping Node heap during `pnpm install`, reuse existing gateway token during `docker-setup.sh` reruns so `.env` stays aligned with config, auto-bootstrap Control UI allowed origins for non-loopback Docker binds, and add GCP docs guidance for tokenized dashboard links + pairing recovery commands. (#26253) Thanks @pandego.
 - Agents/Subagents delivery: refactor subagent completion announce dispatch into an explicit queue/direct/fallback state machine, recover outbound channel-plugin resolution in cold/stale plugin-registry states across announce/message/gateway send paths, finalize cleanup bookkeeping when announce flow rejects, and treat Telegram sends without `message_id` as delivery failures (instead of false-success `"unknown"` IDs). (#26867, #25961, #26803, #25069, #26741) Thanks @SmithLabsLLC and @docaohieu2808.
 - Telegram/Webhook: pre-initialize webhook bots, switch webhook processing to callback-mode JSON handling, and preserve full near-limit payload reads under delayed handlers to prevent webhook request hangs and dropped updates. (#26156)
