# REPORT — v0.171.0: disk-health card device-model label (2026-07-25)

**Overwritten** per the standing rule. Pairs with agent v0.95.0 (SMART coverage); the R-50
island-bridge spike lives in felhom.eu.

## Baseline → target
felhom-controller `de14eed` (v0.170.0) → committed **`f6a8249`** (v0.171.0). Deployed to guest 9201.

## What shipped (additive)
- `agentapi.SmartSummary` gains `ModelName` (mirrors agent v0.95.0 `model_name`, omitempty).
- `diskDisplayLabel` (disk_health.go) now **prefers the device model** over the raw storage name/UUID,
  falling back to `Name` (+ speed hint) on an older agent or a modelless disk. Old-agent payloads render
  exactly as before.
- Files: `internal/agentapi/client.go`, `internal/web/disk_health.go`, `+_test.go`, CHANGELOG.

## Tests + red-proof
`go build/vet/test ./...` — **27 packages pass, 0 fail**; template/emoji/mojibake gates OK.
`TestDiskDisplayLabel_PrefersModel`: model present → model label; old agent / nil model → Name(+hint)
(A4 tolerance). Red-proof: drop the fallback (always return ModelName) → the old-agent/nil cases return
"" and the test fails.

## LIVE acceptance (guest 9201, with agent v0.95.0) — the operator's complaint reversed
Deployed `0.171.0` → Up (healthy). The "Lemezek állapota" card now shows BOTH physical disks with
**real verdicts + human model labels**:
- **"AirDisk 512GB SSD" → Rendben, 34 °C** (the system SSD — Fix A resolved the LVM root).
- **"TOSHIBA MQ04ABF100" → Rendben, 30 °C** (the USB — Fix B + the model label).

No raw UUIDs, no "Nincs adat". `/disks` carries `smart.health=PASSED` + `model_name` for both (see the
agent REPORT). The capability-map row was upgraded to PROVEN-LIVE (healthy path + delivery).

## Observations
- A live FAILING/Figyelmeztetés verdict still needs a genuinely degrading disk (both demo disks are
  healthy) — that arm stays unit + red-proof covered; the notification delivery path is separately
  live-proven (hub 400→200 + email, 2026-07-24).
