 * There is deliberately no setting pointing at a tasks file — one resolution
 * rule, so the drawer and the prompt can never disagree about which file is the
 * queue (Rule #8).
 *
 * Before task 183 the file was found among the thread's always-include entries.
 * Creating a thread scaffolds a `Tasks.md` but persists only `projectDir`, so a
 * new thread had a tasks file that neither the prompt nor the drawer ever saw.
