 - Config/backups hardening: enforce owner-only (`0600`) permissions on rotated config backups and clean orphan `.bak.*` files outside the managed backup ring, reducing credential leakage risk from stale or permissive backup artifacts. (#31718) Thanks @YUJIE2002.
 - WhatsApp/inbound self-message context: propagate inbound `fromMe` through the web inbox pipeline and annotate direct self messages as `(self)` in envelopes so agents can distinguish owner-authored turns from contact turns. (#32167) Thanks @scoootscooob.
 - Exec approvals/allowlist matching: escape regex metacharacters in path-pattern literals (while preserving glob wildcards), preventing crashes on allowlisted executables like `/usr/bin/g++` and correctly matching mixed wildcard/literal token paths. (#32162) Thanks @stakeswky.
+- Agents/tool-result guard: always clear pending tool-call state on interruptions even when synthetic tool results are disabled, preventing orphaned tool-use transcripts that cause follow-up provider request failures. (#32120) Thanks @jnMetaCode.
 - Webchat/stream finalization: persist streamed assistant text when final events omit `message`, while keeping final payload precedence and skipping empty stream buffers to prevent disappearing replies after tool turns. (#31920) Thanks @Sid-Qin.
 - Cron/store migration: normalize legacy cron jobs with string `schedule` and top-level `command`/`timeout` fields into canonical schedule/payload/session-target shape on load, preventing schedule-error loops on old persisted stores. (#31926) Thanks @bmendonca3.
 - Gateway/Heartbeat model reload: treat `models.*` and `agents.defaults.model` config updates as heartbeat hot-reload triggers so heartbeat picks up model changes without a full gateway restart. (#32046) Thanks @stakeswky.
