A worker drains `inject.len() / worker_threads + 1` notifications per batch (tokio 1.53.1 worker.rs:1123), which is 2 when there are two workers: the worker that then blocks in the held destructor can also have captured the second shard's abort into its own local run queue. `push_back` into a local queue notifies nobody, so the surviving worker stays parked on the time driver and never steals it, and `retire(&second)` waits forever. The failure is a hang, not slow work: raising the bound to 120s made the failing run take the full 120.03s while healthy runs finish in <=3ms. A larger timeout therefore cannot fix it. Four workers hold the injection batch at one task each so the blocked worker can only ever capture the shard it is already draining, and leave spare capacity beyond the one worker the destructor consumes. Production retirement is genuinely independent and unchanged: `retire` clones its shard's `Arc` under a short `tasks` lock and awaits only that shard's join state, never holding a cross-shard lock across an await. The coupling was scheduler capacity the test created for itself. Reproduced on origin/master at the same line (1/384 under load ~70), so this is pre-existing and not introduced by the batch.

Both receipt spools enumerate that root and treat any name that is not a receipt or the lock as `UnsafePath`, so the residue made every later open of that project fail: project-open observability producer registration failed: project observability owner mount failed: delivery_settlement_recorder_spool_unsafe `settle_failed_full_upgrade` then records the runtime publication as `Failed`, and the project answers `application.runtime.owner_failed` ("reopen the project") permanently -- reopening could never recover, because the residue is never swept. The staging-name convention belongs to `framed_log`, so the predicate and the sweep live there and both spools use them: the scan skips its own staging names instead of refusing the directory, and each `open` sweeps the residue once its exclusive lease is held, which is the only point at which no live publisher can own one. Found via daemon_suite advanced_workflow_journey_test::mounted_fan_out_recovers_then_synthesizes_and_hands_off, whose second restart is a deliberate "force daemon crash during fan-out" while delivery settlements are being spooled.

The mounted owner's settle pass decodes the active generation inside graph prepare, parks on the same hold, and drops its reconcile-pass guard at registry/mount.rs:1199 before it gets there, so neither the background-reconcile admission nor the quiescence helpers can fence it out. The assertion was therefore a race between the owner reaching the hold and the two readiness calls returning, which the test wins by a few milliseconds on an idle machine and loses on a loaded 4 vCPU runner. Run 35431957131 lost it. Drive the owner into that park first and assert against the floor its park establishes. A park cannot end while the hold is up and the owner is blocked inside the step it parked in, so every later rise in the count is a readiness call joining the decode flight, and the assertion now measures what it claims. Instrument proof: making `latest_complete_ready_decoded_for_root_scope` join the flight fires the assertion with the diff (left: 2, right: 1) instead of passing. Verified on the fixed test: 200 runs at 10-way concurrency, 0 failures; the two sibling decode-flight tests 20 runs each, 0 failures; the whole `code_index_scheduler::tests::serving` module 3 times at `--test-threads=4`, 74 passed each time.
