B2 — the 1-in-3 boot-time READ CAPACITY failure, root-caused: the xHCI library's awaitTransfer claimed ANY unclaimed transfer event as its own completion. An interrupt-endpoint event whose TRB pointer no longer matched the armed subscription (an error or stale completion from the keyboard/mouse polling concurrently with storage bring-up) fell through and was misread as the bulk transfer's completion — desynchronizing the mass-storage bulk protocol in controller state that SURVIVED driver restarts, so every retry failed too. Awaited transfers now match the event's slot id and endpoint DCI; foreign events are dropped and named. Twelve consecutive runs of the previously-flaky cases pass; the full suite is green with none of its old intermittents. B1 — and when storage does fail transiently, the system now heals instead of giving up forever: a nonzero exit maps to ExitReason.aborted (a deliberate FAILURE exit — supervisors restart those with backoff, unlike a clean .exited), usb-storage exits nonzero when a PRESENT device fails bring-up, and the fat service no longer blocks its harness polling for a block device and then dies — it serves immediately (requests fail politely), retries on a 500 ms timer, and mounts whenever storage appears, including after a driver restart. |
