 ## Changelog
 
+### v0.171.0 — Disk-health card: device-model label (pairs with agent v0.95.0) (2026-07-25)
+
+`agentapi.SmartSummary` gains `ModelName` (mirrors the agent v0.95.0 `model_name`); the "Lemezek
+állapota" card row label now prefers the device model ("TOSHIBA MQ04ABF100") over the raw storage
+name/UUID, falling back to Name (+ speed hint) on an older agent or a modelless disk. With agent
+v0.95.0 the system SSD and the USB drive now carry real SMART, so the card shows real verdicts
+(Rendben) with human labels instead of "Nincs adat" on a raw UUID. Additive; old-agent payloads render
+exactly as before. Test `TestDiskDisplayLabel_PrefersModel` (red-proof: drop the fallback → A4 fails).
+
 ### v0.170.0 — Root → Indítópult; gofmt normalization; stale-note fix (2026-07-25)
 
 - **`/` is now the Indítópult** (operator ruling, reversing the v0.163.0 landing choice). `GET /` 302s
