# REPORT — v0.323.0: Debian 13, restic 0.18.1 pinned outside the OS and re-proven, felhom-samba 1.2.0 (2026-10-16)

Brief: „the controller on Debian 13 with a pinned restic, re-proven; the Samba image rebuilt". Full report, in plain
words: felhom.eu `REPORT-debian13-restic-2026-10-16.md`. Evidence: felhom.eu `documentation/audits/debian13-restic-2026-10-16/`.

## 1. What changed

- `controller/Dockerfile`: a `restic` stage fetches the official restic 0.18.1 binary and checks the signed `SHA256SUMS`
  (vendored key, `third_party/restic/`), the published sum and the per-arch sum pinned in the file. Runtime
  `debian:13.7-slim` (digest); Docker repo codename from `/etc/os-release`. Removed packages the binary never runs:
  postgres and mysql clients, sqlite3, fdisk, e2fsprogs, parted, sshpass.
- `infra-images/samba/Dockerfile`: Alpine 3.24.2 (digest). `SambaImage` → `felhom-samba:1.2.0` (pushed once).
  `scripts/build-samba-image.sh` refuses a reused tag, an unanswerable registry and a dirty/unpushed tree.
- Comments in `internal/backup/offbox_{capture,progress,proof,window}.go` corrected to what was measured on both versions.

## 2. Tests (each red-proved)

- `TestR1105_ResticIsPinnedOutsideTheOS` (`cmd/controller`): fails on the old Dockerfile and on four single mutations.
- `TestR1105_EachResticFailureKeepsItsClass`, `_InitRaceIsStillSuccess`, `_TheJSONTheCodeReadsStillParses`,
  `_TheForgetPlanOnlyEverKeepsMore` (`internal/backup`): REAL outputs of 0.14.0 and 0.18.1 in `testdata/restic/`, through
  the code's own parsers and classifiers. Six mutations, each convicted.
- `scripts/test_samba_build_push_once.sh`: 6 cases; 4 fail on the old script.
- Full suite green; `controller_gates.py --fast` green.

## 3. Live

demo-hp 9201 on rc.1 (code identical to the release): both restore directions byte-identical on the real store; the
off-site run (dumps + push, live progress) ok; the drill's row and file came back from the off-site copy; Samba 1.1.0 →
1.2.0 with the same household password, every discovery daemon answering. Released by per-box floors to Tester 1,
demo-hp, demo-felhom (19:25 UTC), box walk green. **The global floor waits for each box's first night on 0.323.0.**

## 4. Observations

1. The forget plan of restic 0.17+ keeps each group's oldest snapshot while monthly slots are unused. NOT-A-FINDING: it only ever keeps more; pinned by `TestR1105_TheForgetPlanOnlyEverKeepsMore`, written into felhom.eu `07` §6.8.
2. A reinstalled database app restored from the off-site copy is unusable (old volume, new password). FILED: R-1106
3. The official restic 0.18.1 binary adds 50 fixable scanner findings. FILED: R-1107
4. A share added before the first household password is not exported. FILED: R-1108
5. A plain `restic restore` writes a lock on both versions; a comment said it did not. NOT-A-FINDING: comment corrected; the nightly proof uses `--no-lock`.
6. `build.sh --push` also pushes `:latest` for an rc tag. NOT-A-FINDING: nothing pulls `:latest`; boxes run a named tag and the update button reads X.Y.Z tags.
