v0.342.0 (unreleased): the upload watch reads the host's weekly line test (GET /host/line-test, agent >= 0.164.0); qBittorrent's limit = 50 % of the TESTED line only (D41), the watch uses the higher of test and push floor, the system page names the source; red-proved

+- **2026-10-24 (attended release run; operator rulings D41 = 50 %, D42, the line test): the TESTED line.** The night's
+  one-second read showed the push floor is far below the line (demo-hp „at least 10 Mbit/s"; a real test: 90.7). So the
+  controller now reads the host's **weekly iperf3 line test** from the agent (`agentapi.LineTest`, `GET /host/line-test`,
+  agent ≥ 0.164.0 — an older agent answers 404 = „not measured"; MinAgent stays 0.158.1). **qBittorrent's limit is 50 %
+  of the TESTED line only** — never of the push floor; no test yet → no limit. The watch judges against the higher of the
+  two. The value is read at start and every 15 minutes (a failed read keeps the last value). The system page names the
+  source: „N Mbit/s (heti sebességméréssel)" / "N Mbit/s (measured weekly)", or „legalább N … (az éjszakai távoli
+  mentésből)" for the floor. Tests (each red-proved): `TestService_QBLimitFromTheTestedLineOnly`,
+  `TestUpwatch_SystemPageNamesTheLinesSource`, `TestLineTestDecodesAndAnOlderAgentIs404`, `TestUpwatchIsWiredAtStartup`
