# Controller A failed-SD compact preservation manifest

Status: complete
Type: evidence
Updated: 2026-07-25
Next Action: none; retain this manifest and the governed generated-evidence archive
Parent: work/incidents/incident-control-a-sd-card-read-failure-20260722.md

## Retention decision

The SMI firmware workspace owner selected the repository's governed,
Git-ignored generated-evidence area as the durable destination:

`work/evidence/generated/smi-control-a-failed-sd-20260722-compact-evidence.tar.gz`

The 7,948,206,080-byte raw recovery image was intentionally not duplicated.
Its incremental project value does not justify 7.95 GB of retained workspace
storage unless a future quality, regulatory, or forensic requirement calls for
full filesystem reanalysis. The failed physical card remains the failure
specimen. This compact archive retains the recovery map, recovered files,
recovered-file hash list, carved binary and CSV records, and rsync log.

After the compact archive was hash-verified, the owner explicitly directed
deletion of the original raw image. The root-owned
`/var/tmp/smi-control-a-failed-sd-20260722.img` was deleted from
`srv-rpi00.local` on 2026-07-25 and its absence was verified. This deletion is
not recoverable from the server; the compact archive and physical failed card
remain.

## Capture and verification

- Source host: `srv-rpi00.local`
- Source directory: `/var/tmp`
- Capture method: GNU `tar -czf` over the compact evidence set; no failed-card
  access, format, repair, or mutation was performed.
- Transfer method: `scp` from `srv-rpi00.local` to the governed generated
  evidence path.
- Archive size: `19,563,639` bytes
- Source SHA-256:
  `ae1acf7928dd887c9c2ea182c448e8c56aeaf667d4d958f34e0f2cc7c881f384`
- Destination SHA-256:
  `ae1acf7928dd887c9c2ea182c448e8c56aeaf667d4d958f34e0f2cc7c881f384`
- Verification result: source and destination hashes match.
