# REPORT — controller v0.339.0 released (2026-10-22 day brief)

**What:** R-1199 reopened — a rebuilt box never overwrites the household's saved mail list; R-1216 (D28 = A) — the
install page's swap sentence only when host swap is really short. Design: `08-alarm-ladder.md` (the 2026-10-22
`[DESIGN]` paragraph), `03-host-agent.md` (guest swap), `05` (`customer_notifications`). **MinAgent 0.158.1**; needs hub
≥ 0.165.0 (deployed first, operator yes).

- **Found:** v0.338.0's start-up default push replaced demo-felhom's own 13-event list on the hub with the 17 defaults
  (07:54:55 UTC) and would repeat at every start. Now a box with no list of its own reads the hub's: adopts a
  household's (nothing pushed), pushes its default once only when no household saved one, sends nothing when the hub
  cannot be read. Every push names its `source`. Red-proved against v0.338.0's rule.
- **Fixed without a row:** an empty saved list read back as the 17 defaults (`omitempty`; Tester 1 and demo-hp hold
  that file shape) — now `[]` persists and a saved list with no events reads as empty; the add-only seeds are marked
  done on a fresh settings file (they re-added a just-switched-off mail at a new box's second start). Red-proved.
- **R-1216:** `hostSwapRuleShort` = no host swap, or < 90 % of min(guest swap, 8192 MB); the hub's case table copied
  byte-identical (`testdata/host_swap_rule_cases.json`, felhom.eu `host_swap_rule_gate.py`). Red-proved.
- **Release:** rc.1 on 9202 (`sha256:7d4c8852…`; no hub link there — start-up and pages only: healthy, 0 errors,
  `/login` 200). `0.339.0` from `fc5a20f` (CI 2209 green): `sha256:fee71aafceb4a7d5f24ae4a6a273a8d51eb26e0550fe9d12d4d86955f6a343a8`.
  Per-customer floors → Tester 1, demo-hp, demo-felhom on 0.339.0 within 40 s; 10/24/9 containers, 0 unhealthy, 0
  restarting, 0 errors; https-only every name 301. demo-felhom logged „adopted the household's saved list from the hub
  (13 events …) — nothing pushed"; its box file and the hub row now agree. Global floor 0.339.0 / 0.158.1 (read back
  with the WAL, 11:14:21 UTC); per-customer floors cleared. Evidence felhom.eu `documentation/audits/day-2026-10-22/`.
