- Agents/sessions: keep delayed `sessions_send` A2A replies alive after soft wait-window timeouts, while preserving terminal run timeouts and avoiding stale target replies in requester sessions. Fixes #76443. Thanks @ryswork1993 and @vincentkoc.

- Config/doctor: cap `.clobbered.*` forensic snapshots per config path and serialize snapshot writes so repeated `doctor --fix` recovery loops cannot flood the config directory. Fixes #76454; carries forward #65649. Thanks @JUSTICEESSIELP, @rsnow, and @vincentkoc.

- Feishu: suppress duplicate text when replies send native voice media while preserving captions for ordinary audio files and falling back to text plus attachment links when voice uploads fail.

- Feishu: keep packaged Feishu startup from bundling the Lark SDK's ESM `__dirname` path by loading the SDK as a plugin-local runtime dependency. Fixes #76291 and #76494. (#76392) Thanks @zqchris.

- Channels/secrets: resolve SecretRef-backed channel credentials through external plugin secret contracts after the plugin split, covering runtime startup, target discovery, webhook auth, disabled-account enumeration, and late-bound web_search config. Fixes #76371. (#76449) Thanks @joshavant and @neeravmakwana.

- Docker/Gateway: pass Docker setup `.env` values into gateway and CLI containers and preserve exec SecretRef `passEnv` keys in managed service plans, so 1Password Connect-backed Discord tokens keep resolving after doctor or plugin repair. Thanks @vincentkoc.

- Control UI/WebChat: explain compaction boundaries in chat history and link directly to session checkpoint controls so pre-compaction turns no longer look silently lost after refresh. Fixes #76415. Thanks @BunsDev.
