hub-db-backup: wait for a snapshot being written, limit 7 h (one slot gap + 1 h) — the 2 h limit refused the hub's own catch-up and mailed a false failure at 10:28 (R-1234, closed); tests red-proved

 ## 2026-10-23 — `release-copy/`: the released images and agent packages leave DooPlex nightly (D33, R-1227); `hub-db-backup/`: every 6 hours (D34)
 
 - **`release-copy/felhom-release-copy`** (new, DooPlex root, timer 01:40): the newest 3 release tags of felhom-controller, felhom-hub and felhom-samba (`skopeo copy --all --preserve-digests` into `dir:` — the registry's own bytes, so a push back gives the SAME digest; a `docker save` tar would not) and the newest 5 agent versions (binary + config bundle). Before anything leaves: the top manifest hashes to the registry's digest, every blob and child manifest to its name, every named blob is present, each agent file matches the registry's sha256; the staged tree ≤ the cap (3072 MB). Then `rsync --delete` to ep0's limited user `felhom-relcopy` (rrsync, one directory), and a `--checksum --dry-run` must show no difference before the success signal. Spoiled tags (0.315.0, 0.316.3) are never copied. 13 tests (`test_release_copy.py`), four red-proved.
-- **`hub-db-backup/`** — the push runs at 02:30, 08:30, 14:30 and 20:30 (the hub snapshots every 6 hours since hub 0.167.0) and refuses a newest snapshot older than 2 h (was 26 h). Tests: the timer read against the hub's slots; a missed slot is refused.
+- **`hub-db-backup/`** — the push runs at 02:30, 08:30, 14:30 and 20:30 (the hub snapshots every 6 hours since hub 0.167.0) and refuses a newest snapshot older than 7 h (one slot gap + 1 h; was 26 h), and waits (up to 20 min) while the hub is writing one. **Corrected the same day:** 2 h was shipped first, and its first run refused the timer's own catch-up while the hub's start-up snapshot was still being written — one false failure mail to admin@ at 10:28 (R-1234). Tests: the timer read against the hub's slots; two missed slots refused; a restart within one slot pushed; a snapshot being written waited for — each red-proved (the last reproduces the 10:28 run).
 
 ## 2026-10-23 — felhom-host-install.sh 1.36.0 (pushed; the tag `installer-v1.36.0` waits for the operator's yes): the uninstall removes the root-SSH drop-in (R-982, D4)
