From the 2026-08-24 Sloane CUJ test (issue #64): the fatal send failure left no trace in the Activity work log, and what the log did show read as infrastructure ('FILES_BRIDGE_SYNCED VIA FILES — 0 folder grant(s) delivered via brokered_read_only'). - finalize_thread_run now writes a 'run_failed' audit entry ('Attempted a task and failed: <error>') at the single chokepoint every failure path goes through — success already logged 'chatted'; failures were invisible, which is exactly what let a false 'I'm on it' claim go unchallenged by the log meant to verify it. - ActivityTab renders human action labels ('Files synced', 'Task failed', 'Chat') with the machine code preserved in the hover title. run_failed entries pick up the existing red failed styling.

Fixes #64 — from the 2026-08-24 Sloane health-forms CUJ test: the run's fatal failure left zero trace in the Activity work log (so the log couldn't confirm or deny the agent's false "I'm on it" claim), and existing entries read as infrastructure codes.
Changes
finalize_thread_runwrites arun_failedaudit entry ("Attempted a task and failed: ") — the one chokepoint all failure paths pass through. Success already loggedchatted; this is its counterpart.run_failedautomatically picks up the red failure styling.Testing
