 ### Fixes
 - Browser: add tests for snapshot labels/efficient query params and labeled image responses.
+- macOS: ensure launchd log directory exists with a test-only override. (#909) — thanks @roshanasingh4.
 - Telegram: register dock native commands with underscores to avoid `BOT_COMMAND_INVALID` (#929, fixes #901) — thanks @grp06.
 - Google: downgrade unsigned thinking blocks before send to avoid missing signature errors.
 - Agents: make user time zone and 24-hour time explicit in the system prompt. (#859) — thanks @CashWilliams.
