-last night's data-safety fixes and one fix made today: a box that seeds torrents all day now gets its weekly line test.
-The old hold asked the line test too early — qBittorrent keeps sending for about 14 seconds after it is slowed — so
-the test was refused every time. Now the controller waits until the app has really slowed down.
+**Plain words first.** Four commits are on main, each with CI green and each new test seen failing first. Nothing is
+released: the night brief allowed no release. The controller release goes on the morning list. It needs no new MinAgent:
+with an older agent the OOM count answers 404 and the controller waits 10 minutes before it asks again.
 
-## What 0.346.0 carries
+**Decided by CC unattended — operator may reverse:** an unused restore copy goes after 14 days (options: 14 days, for
+ever, 3 days; `07` §6.3 [DESIGN] 2026-10-28). H4 and H5's failed-stop branch keep only test proofs; their live proof is
+owed to an attended session (or revert those two branches of `342a394`).

H4: an off-site restore whose definition write fails writes the LIVE definition back before the start; a failed write-back holds the app. H5: a put-back whose stop fails pours nothing, keeps the copy, holds the app; a failed definition write-back keeps the copy (D20); a `volume rm -f` that fails fails that volume (no merge on top of the old content). H6: a restore begins in ONE step with the check for a restore, the backup run and a second-drive copy (`TryBeginRestoreOp`); every restore button and both kept loads begin that way.

-- Before (0.345.1 on demo-hp 9201, a throwaway qBittorrent seeding to DooPlex): four holds 11:36–12:21 CET, each
-  refused „not quiet" 4.0–4.2 Mbit/s. Per-second reads: qBittorrent reports its limit 1024 within a second but sends
-  at full speed ~14 s; the forwarder and UDP queues hold nothing (felhom.eu `audits/linetest-2026-10-27/`).
-- Fix: `upwatch.waitDrained` — after the hold, poll each held app's own upload (`Holdable.UploadRate`: qBittorrent
-  `up_info_speed`, Transmission `uploadSpeed`) until ≤ 16 KiB/s twice, 2 s apart; at most 90 s; an unreadable speed
-  waits 20 s; then ask the agent. Tests `linehold_r1250_drain_test.go` (five), red-proved by four mutations.
-- After (0.346.0-rc.1 on 9201): held 13:39:56 → slowed after 22 s → 94.5 Mbit/s → the limit back exactly; the 50 % rule
-  kept the normal slot (0.15 % move).
