 - CLI/doctor: trust a ready gateway memory probe when CLI-side active memory backend resolution is unavailable, preventing false "No active memory plugin is registered" warnings for healthy runtime setups. Fixes #76792. Thanks @som-686.
 - Memory/status: keep plain `openclaw memory status` and `openclaw memory status --json` on the cheap read-only path by reserving vector and embedding provider probes for `--deep` or `--index`. Fixes #76769. Thanks @daruire.
 - Telegram: suppress stale same-session replies when a newer accepted message arrives before an older in-flight Telegram dispatch finalizes. Fixes #76642. Thanks @chinar-amrutkar.
+- Gateway/diagnostics: abort-drain embedded runs after an extended no-progress stall so a single dead session no longer leaves queued Discord/channel turns blocked behind repeated `recovery=none` liveness warnings.
 - Control UI/Sessions: avoid full `sessions.list` reloads for chat-turn `sessions.changed` payloads, so large session stores no longer add multi-second delays while chat responses are being delivered. (#76676) Thanks @VACInc.
 - Gateway/watch: run `doctor --fix --non-interactive` once and retry when the dev Gateway child exits during startup, so stale local plugin install/config state does not leave the tmux watch session disappearing without a repair attempt.
 - Doctor/Telegram: warn when selected Telegram quote replies can suppress `streaming.preview.toolProgress`, and document the `replyToMode` trade-off without changing runtime delivery. Fixes #73487. Thanks @GodsBoy.

 - `agent.wait` default: 30s (just the wait). `timeoutMs` param overrides.
 - Agent runtime: `agents.defaults.timeoutSeconds` default 172800s (48 hours); enforced in `runEmbeddedPiAgent` abort timer.
 - Cron runtime: isolated agent-turn `timeoutSeconds` is owned by cron. The scheduler starts that timer when execution begins, aborts the underlying run at the configured deadline, then runs bounded cleanup before recording the timeout so a stale child session cannot keep the lane stuck.
-- Session liveness diagnostics: with diagnostics enabled, `diagnostics.stuckSessionWarnMs` classifies long `processing` sessions that have no observed reply, tool, status, block, or ACP progress. Active embedded runs, model calls, and tool calls report as `session.long_running`; active work with no recent progress reports as `session.stalled`; `session.stuck` is reserved for stale session bookkeeping with no active work, and only that path releases the affected session lane so queued startup work can drain. Repeated `session.stuck` diagnostics back off while the session remains unchanged.
+- Session liveness diagnostics: with diagnostics enabled, `diagnostics.stuckSessionWarnMs` classifies long `processing` sessions that have no observed reply, tool, status, block, or ACP progress. Active embedded runs, model calls, and tool calls report as `session.long_running`; active work with no recent progress reports as `session.stalled`; `session.stuck` is reserved for stale session bookkeeping with no active work. Stale session bookkeeping releases the affected session lane immediately; stalled embedded runs are abort-drained only after an extended no-progress window (at least 10 minutes and 5x the warning threshold) so queued work can resume without cutting off merely slow runs. Repeated `session.stuck` diagnostics back off while the session remains unchanged.
 - Model idle timeout: OpenClaw aborts a model request when no response chunks arrive before the idle window. `models.providers.<id>.timeoutSeconds` extends this idle watchdog for slow local/self-hosted providers; otherwise OpenClaw uses `agents.defaults.timeoutSeconds` when configured, capped at 120s by default. Cron-triggered runs with no explicit model or agent timeout disable the idle watchdog and rely on the cron outer timeout.
 - Provider HTTP request timeout: `models.providers.<id>.timeoutSeconds` applies to that provider's model HTTP fetches, including connect, headers, body, SDK request timeout, total guarded-fetch abort handling, and model stream idle watchdog. Use this for slow local/self-hosted providers such as Ollama before raising the whole agent runtime timeout.
