task_runs.tokens_in only ever held the API's uncached "input_tokens" field
(off by a factor of ~400,000 on a resumed session), and tokens_out summed
only the last result event instead of the whole session. TaskRunner now
reads each run's cache-read/cache-write/input/output totals from the
session transcript via a new ITranscriptUsageReader.ReadSessionTotalsAsync,
storing the delta against prior runs on the same session so a --resume
doesn't double-count. New task_runs.cache_read_tokens/cache_write_tokens
columns; the Session tab now shows the raw total (what actually counts
against the 5h/7d usage limit) with a breakdown tooltip.
TaskRunner appends attached files (absolute paths) to the run prompt as the
read-only Reference files section. Task and list deletes now remove the
on-disk attachment dir eagerly, and a startup AttachmentOrphanRecovery sweep
drops any attachments/<taskId>/ whose task no longer exists (covers list
cascade and planning-discard paths).
Befund (bestätigt): src/ClaudeDo.Worker/Runner/TaskRunner.cs:101 (RunAsync) und :211 (ContinueAsync) ignorieren das TransitionResult von _state.StartRunningAsync. Race-Szenario: Der QueuePicker claimt Queued→Running atomar; ruft der Override-Pfad (RunNow) kurz danach RunAsync für denselben Task auf, schlägt StartRunningAsync fehl (0 rows affected), der Runner startet Claude aber trotzdem → derselb
