# REPORT — 2026-09-28: v0.277.0 (kept data from the off-site copy, R-691 (2)) and v0.278.0 (leftover holds, R-704)

Architecture read first: `felhom.eu/documentation/architecture/07-backup-architecture.md` §6.5 (kept data), §6.6 (which
version a restore brings back); `06-offsite-connectivity.md` (what the off-site copy holds per app).

## What changed

- `backup.KeptBestCopy`: the newest usable LOCAL copy (own unit, second drive) or the OFF-SITE copy when it is newer or
  the only one (a tie goes local). One `snapshots --json`, bounded 20 s; the kept list asks once per page.
- The install choice and the kept list name the copy and its date (`kept.choice.use.desc_from`, `kept.backup.offsite`).
- `backup.LoadKeptOffsite`: download the unit ALONE (the proof's `restoreUnitReadOnly`, proof scratch) → judge (this
  drive, holds data, data version RECORDED — `07` §6.6, else refused; mixed/mismatched refused by `unitVersionCheck`) →
  `prepare` (a dated folder's files move back) → the one unit restore → scratch removed BEFORE the outcome is reported.

## Tests and red-proofs (`felhom.eu/documentation/audits/kept-offsite-2026-09-28/redproofs/`)

| test | red-proof | failed with |
|---|---|---|
| `TestR691_OffsiteCopyIsOfferedWhenItIsTheOnlyOrNewest` + `TestR691_InstallChoiceNamesTheOffsiteCopy` | RP1: `KeptBestCopy` = `KeptDBCopy` (0.276.0) | `ok=false`; `use_offered=false use_off="There is no backup…"` |
| `TestR691_OffsiteLoadRefusalsLeaveTheKeptFilesAlone` | RP2: the `data`-block refusal removed | "the load reported success" |
| `TestR691_OffsiteLoadDownloadsJudgesThenRestores` | RP3 (seen in the first draft): scratch removed in a `defer` | "the downloaded copy was left behind" |

`go build/vet/test ./...` green; `controller_gates.py` all OK (go-parity needed the 4 new keys listed).

## Live

- 9202 (endpoint level, the calls the pages make): Tier 1 route unchanged — the choice named „saját mentés,
  2026-09-28 10:06"; "use" loaded 3/3 volumes + 1/1 database; the seeded nextcloud user and file read back.
  Tier 2 not runnable live (9202 has one drive). 9202 has no off-site target, so the off-site path is not asked there.
- Floor 0.276.0 → **0.277.0** (MinAgent 0.131.0) at 08:11Z; both demo boxes on 0.277.0, healthy, within a minute.
- **Off-site route PROVEN LIVE on demo-hp 9201 (0.278.0).** The choice named "távoli mentés, 2026-09-28 15:40"; "use my
  kept data" downloaded the unit alone and loaded 3/3 volumes + 1/1 database in 55 s; the seed and files read back
  (`felhom.eu/documentation/audits/kept-offsite-2026-09-28/E/`).

## v0.278.0 — R-704 (a second release this session; the rule is one)

- Found live: a 2026-09-13 update hold on demo-hp outlived its nextcloud; the fresh nextcloud was then skipped by the
  backup leg (no volumes, no unit) and its off-site snapshot held no data. On 9202 a calcom crash-loop stop outlived
  two removals and refused the new install's update.
- Fix: removal clears the crash-loop stop too (`settings.ClearUpdateHold`); a new install (plain or "use my kept data")
  drops a leftover update/crash-loop hold of an app that is not installed (`Router.dropLeftoverHold`). Restore holds
  (R-379) untouched. Tests `TestR704_*`; red-proofs RP4–RP6 each seen failing. Floor 0.278.0, both boxes healthy.
- Not proven live: the install-time drop itself (the demo-hp hold was cleared by the removal, R-491's path).
