B5 — the first night, no hands. Written 2026-10-20 20:25 UTC, BEFORE the night.

Schedule, read from the box's own backups page (local CEST = UTC+2):
  database copy 02:30 (00:30Z) · local copy (second drive) 03:30 (01:30Z) · off-site 04:15 (02:15Z) ·
  whole-box backup between 04:30 and 08:30 (02:30Z–06:30Z), to the local store and the PBS server.

No hands: from 21:00Z until the morning nobody acts on the box as the household or as the operator. Two passive
readers keep running from DooPlex (they change nothing): B4-use/health-log.txt (health every 60 s) and
B4-use/memwatch.txt (the box's own memory/CPU numbers every 30 s). Nothing else touches Tester4.

Expected, each with a POSITIVE observable to look for in the morning:
1. Database copy at ~00:30Z for all 8 apps — the backups page „Utolsó adatbázis-mentés" dated tonight; the box log
   shows the dump lines with tonight's time.
2. Local copy at ~01:30Z — the second-drive card dated tonight (hdd_2 was removed again in #13; if no second drive
   is assigned, the page must SAY there is none, not show a success).
3. Off-site at ~02:15Z — „Távoli mentés" ok with tonight's date; the snapshot list holds one new snapshot per class.
   Morning: compare per class with the A5 manifest (counts and sha256 of a sample), and check the films share.
4. Whole-box backup 02:30Z–06:30Z — „Utolsó teljes mentés" dated tonight on local and PBS.
5. The box does not freeze (R-1192): memwatch keeps answering; health 200 every minute.
6. Mail: the household gets nothing on a good night; the operator gets nothing about Tester4 on a good night.
Anything missing from 1–6 is a finding, written with its evidence before any fix or retry.

Baseline taken 20:59–21:09 UTC (before the night, read-only, through the apps' own front doors): `01-before-night-snapshot.txt`
(tool `tools/snapshot.py`). The morning snapshot must equal it line for line. The four known Nextcloud gaps are from
the day (the 1.5 GB upload that never finished, a symlink WebDAV cannot hold, the NFC/NFD pair Nextcloud folds into one
name) and the four 0-byte `feltoltes_*.jpg` are R-1196.

Added 21:39 UTC, before the night: a THIRD passive reader, `tools/logwatch.py` — every 10 min it copies the box's own
log ring (the „Hibakeresés" page's data: controller INFO+ and the host agent's lines) off the box, because a restart
erases it. Read-only, like the other two. The copies are scanned for secrets before they are committed.
