# Ticket: Preserve Controller A failed-SD recovery evidence

Status: complete; compact evidence preserved and raw-image duplication explicitly declined
Type: ticket
Updated: 2026-09-23
Next Action: none; retained as history; any new execution requires a new explicit owner instruction
Campaign Reason: Historical record from campaign 011-qualify-degraded-sd-operation-and-logging-integrity; retained independently after campaign closure and requires no separate owner-queue execution.
Campaign: standalone
Parent: work/incidents/incident-control-a-sd-card-read-failure-20260722.md
Project Map: work/maps/map-smi-firmware-stabilization-and-qualification.md

## Problem

The July 22 recovery image, map, recovered files, hashes, and carved records are
reported under `/var/tmp` on `srv-rpi00.local`. That location is not durable
project evidence and may be cleaned without warning.

## Known source set

- `/var/tmp/smi-control-a-failed-sd-20260722.img`
- `/var/tmp/smi-control-a-failed-sd-20260722.map`
- associated recovered files, hashes, and carved-record outputs with the same
  incident prefix

## Acceptance criteria

- [x] Destination and retention owner are explicitly selected.
- [x] Source files are inventoried read-only before copy.
- [x] Large images remain outside Git; the repository stores a manifest,
  cryptographic hashes, capture method, source/destination, and access route.
- [x] Source and destination hashes match.
- [x] The incident links the durable manifest.
- [x] No format, repair, or additional mutation of the failed card is performed.

## Closeout

The retained compact archive and verification record are documented in
`work/evidence/controller-a-failed-sd-compact-preservation-20260725.md`.
The owner explicitly declined duplicating the 7.95 GB raw recovery image
because its incremental value did not justify the storage cost. The recovery
map, recovered files and hashes, carved outputs, and transfer log were retained
in a 19.56 MB archive with matching source and destination SHA-256 hashes.

## Owner-directed reconciliation — 2026-09-23

Reconcile stale active lifecycle to the previously documented completed disposition; no new test or broader acceptance claim.

Authorization: Owner instruction in this conversation on 2026-09-23 to close/abandon the named work and mitigate older active records.

Previous header retained for evidence interpretation:

> Status: complete; compact evidence preserved and raw-image duplication explicitly declined
> Next Action: none; retain work/evidence/controller-a-failed-sd-compact-preservation-20260725.md

Earlier observations, unchecked historical criteria, and procedures below/above remain history. This administrative disposition does not qualify a new firmware candidate, physical card, thermal system, ECO, or release. Current 00.05.01 obligations in IDEA-0006, IDEA-0007, MAP-0009, and CAMP-0028 remain unchanged.
