## Outcome

Five consecutive powered insertions of `USB03_32G` passed on the deployed
diagnostic-only candidate without a reseat, VBUS action, controller power
action, or specimen-specific behavior. Controller A covered observations 1,
2, and 5; Controller B covered observations 3 and 4.

| Observation | Controller | Media generation | USBHS state | USBX device | Result |
| ---: | --- | ---: | --- | --- | --- |
| 1 | A | 1 | `SYSSTS0=0x8060`, `DVSTCTR0=0x0213` | configured, address 1, high speed | PASS |
| 2 | A | 2 | `SYSSTS0=0x8060`, `DVSTCTR0=0x0213` | configured, address 1, high speed | PASS |
| 3 | B | 1 | `SYSSTS0=0x8060`, `DVSTCTR0=0x0213` | configured, address 1, high speed | PASS |
| 4 | B | 2 | `SYSSTS0=0x8060`, `DVSTCTR0=0x0213` | configured, address 1, high speed | PASS |
| 5 | A | 3 | `SYSSTS0=0x8060`, `DVSTCTR0=0x0213` | configured, address 1, high speed | PASS |

Every capture reported HCD operational state `2`, connection bitmap `1`, one
device, valid FileX publication, zero USBX system errors, zero USB application
errors, and zero controller system errors. The natural failure did not recur
in this five-observation window.

## Failure disposition supported by prior captures

The earlier repeated misses are below FileX and USB Mass Storage class
publication. Their final state retains physical attachment and the USBX root
device, records `UX_DEVICE_ENUMERATION_FAILURE`, and has no pending root-hub,
HCD-thread, or enumeration-semaphore signal. A clean reseat creates the missing
new root-port event and then enumerates normally. That state supports one
standards-led root-port re-enumeration attempt; it does not support changing
the proven 32 KiB write path, identifying a drive model, replaying writes, or
cycling VBUS.

## Controller and SD identity

The observations retain same-run controller and SD evidence. Controller A was
assembly `1751136`, hardware variant `0`, J-Link `69664082`, with raw CID
`035344535330384780976F0084018559`. Controller B was assembly `1751219`,
hardware variant `1`, J-Link `69660123`, with raw CID
`035344535330384780976F0085018507`. Both cards reported protocol state `5`,
CID valid, representative-sector read valid, MID `03`, OEM `SD`, product
`SS08G`, revision `8.0`, and manufacturing date `2024-05`. No SD card was
removed or inserted.

The raw directories are intentionally ignored; this summary is the versioned
manifest. The five passes strengthen the successful-path evidence but do not
prove recovery until a failed enumeration actually triggers the bounded retry.
