Previously most of these call sites ignored the failure.\n\n**Details**\n\n- The degraded-outcome path for a failed mailbox write went from one call site to nine.\n- Lock releases are wrapped so a failed release logs a warning instead of escaping the surrounding cleanup block.\n- Inbox write errors are now logged at error level and filtered before being surfaced.\n\n**Evidence**\n\n`The confirmation could not be written to team-lead's inbox.`\n\n- Area: Team Messaging\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5"}
