+**Repo:** `felhom-controller` · **Version:** 0.43.0 · **Date:** 2026-06-11
+**Pushed commit:** `29a9dcd` · paired with `felhom-agent` v0.22.0 (`4734d4a`, exposes `durable_id`) + golden rebake.
 
 ## What shipped
 
-The base-infra traefik obtained **no** real cert (acme.json empty) — both routers relied on the
-websecure entrypoint-default `certResolver`, which does **not** trigger proactive DNS-01 issuance, so
-everything ran on traefik's self-signed default (masked externally only by the tunnel's `noTLSVerify`).
-This blocked LAN-direct (a LAN client TLS-handshakes straight to traefik and needs the real cert).
+After the 8C de-privileging the storage UI's buttons pointed at deleted routes (all 404); only manual
+"add already-mounted path" survived. The agent already owns disk execution + the data-bearing signature
+gate, and the controller already had the `agentapi` client + `/api/disks/*` proxies + the `StoragePath`
+registry. This is a **controller-only UI/orchestration layer** over those — the controller holds **no
+destructive authority**.
 
-- **`infra.RenderControllerRoute(domain, wildcardTLS)`** — the always-present controller route is now
-  the **wildcard-issuance anchor**: when DNS-01 ACME is configured (`CFAPIToken && Email`) it carries
-  router-level `tls.certResolver: letsencrypt` + `tls.domains: [{main: "*.<domain>", sans: ["<domain>"]}]`,
-  so traefik **proactively obtains `*.<domain>` + apex at startup** via Cloudflare DNS-01. Every other
-  router (filebrowser, future apps) then serves that one wildcard by SNI match — **no per-app
-  certresolver labels**, real cert ready before the first client connects. `stacks.wireController` passes
-  `wildcardTLS = (CFAPIToken != "" && Email != "")`.
-- **Key empirical finding (staging on 9201):** traefik v3 issues a cert from a **router-level**
-  `tls.domains` but **NOT** from the entrypoint-level `http.tls.domains` (acme.json stayed 0 bytes with
-  the latter). v0.42.0's entrypoint-domains attempt + `TraefikData.Domain` was reverted.
+- **Storage overview** (`settings.html`, `GET /api/disks`): the agent's live disk view — name/type/state/
+  device/mount/class + the **`data_bearing` badge** + a "registered?" cross-reference.
+- **Guided init** (`/settings/storage/init` + `POST /api/storage/init`): format → resolve the new fs UUID
+  from the re-listed disks → assign (mount) → register the `StoragePath`. **A data-bearing device is
+  REFUSED** by the agent; the UI surfaces the exact `felhom-opsign …` command and **stops** — no force-format.
+- **Guided attach** (`/settings/storage/attach` + `POST /api/storage/attach`): non-destructive — resolve
+  the existing fs UUID → assign → register.
+- **Eject** (`POST /api/storage/eject`): benign unmount + deregister, surfacing the agent's dependent-guest warning.
+- **`agentapi`**: `DiskInfo.DurableID` + `FSUUID()` (the assign key — strip `uuid:`); `FormatResult.PendingOp`
+  + `OpsignCommand()`, now parsed from the agent's 403 body (the old client discarded it).
+- **Honest buttons**: init/attach wired; migrate (drive + per-stack, both places) disabled "Hamarosan" — **no 404s**.
+- **Phase 3 (de-priv template debt)**: removed the dead `CrossDrive*` blocks in `deploy.html` (the "2.
+  mentés" form + 3 JS fns) and `backups.html` (run buttons + 2 JS fns) — they referenced fields the
+  de-privileged handlers no longer provide.
 
-## Validation (staging → prod on guest 9201)
-- **CF token pre-check:** active, scoped to `demo-felhom.eu`, DNS read OK (DNS:Edit confirmed by the run).
-- **Staging (Fake LE):** with the router-level wildcard, acme.json went 0 → populated; `felhom.*`,
-  `files.*`, and arbitrary `anything.demo-felhom.eu` all presented `*.demo-felhom.eu` (issuer `(STAGING)`)
-  — one wildcard, zero per-app labels.
-- **Prod switch:** wiped acme.json, clean first-boot render (no `caServer`, no entrypoint domains) →
-  PROD wildcard issued (acme.json ~16 KB).
-- **GATE (from dooplex, real LAN host, direct to guest IP):** `felhom.demo-felhom.eu` + `files.demo-felhom.eu`
-  → **`200 ssl_verify=0`**; issuer **`C=US, O=Let's Encrypt, CN=YR1`** (real prod LE); subject
-  `CN=*.demo-felhom.eu`, SAN `*.demo-felhom.eu, demo-felhom.eu`. Dashboard title `Vezérlőpult — Felhom.eu`.
+## Security invariant — held, proven live
+The UI **never** bypasses the agent's data-bearing gate; there is **no force-format**. A refusal surfaces
+the `felhom-opsign` command only. Unit-tested (`runStorageInit` on a data-bearing refusal performs **zero**
+assign/register) **and** proven live on 9201's real `sdb`:
+`POST /api/storage/init {device:/dev/sdb1}` → **HTTP 409**, `refused:true`, `registered:false`,
+`opsign: felhom-opsign -op storage_wipe -host demo-felhom-01 -durable-id byid:wwn-0x5000039ddb108568-part1`.
+No format, no mount, no registration.
 
-## Live deploy
-- Built + pushed `0.42.1`; deployed to 9201 (clean first-boot: wipe acme.json → controller renders prod
-  traefik.yml + wildcard route → traefik obtains the prod wildcard).
-- **Golden rebaked** with controller 0.42.1 → `local:backup/vzdump-lxc-9100-2026_06_11-18_10_11.tar.zst`
-  (fresh provisions get a real wildcard cert on first boot).
+## Live validation (guest 9201, real 1TB USB `sdb` = `felhom-usb`)
+- `/api/disks` now carries `durable_id`; `felhom-usb` → `/dev/sdb1`, `data_bearing:true` ("device is
+  mounted"), `durable_id:uuid:277a2179-…`. Overview badge maps correctly.
+- **Init on sdb (data-bearing) → 409 + opsign, gate held** (the spec's passing gate test — sdb holds data).
+- Pages render (no 404/500): `/settings`, `/settings/storage/init`, `/settings/storage/attach`,
+  `/stacks/<app>/deploy` (deploy.html — CrossDrive removed), `/stacks`, `/monitoring`. No dead storage links.
+- Tests: refusal-surfaces-opsign-and-does-NOT-mount/register; success assigns with the resolved UUID +
+  registers the expected `StoragePath`; UUID resolution; a **template-parse test** guards every page.
+
+## Deferred / flagged (NOT in this slice)
+- **Phase 2 — migration (controller-side rsync):** intentionally its own slice (the migrate buttons are
+  disabled "Hamarosan", not dead). The controller still has `/mnt:/mnt:rw`, so it can rsync app-data
+  between mounts + update `app.yaml`'s `HDD_PATH` (stop→rsync→verify→start) — no agent endpoint needed.
+- **`/backups` still 500s on PRE-EXISTING restic debt (NOT this change, NOT CrossDrive).** The page
+  references ~30 dead restic-tier fields (`.Backup.RepoStats`, `.SnapshotHistory`, `.ResticSchedule`,
+  `.Retention`, `.LastBackup`, `.NextBackup`, `.LastCheckOK`, …) that 8C removed from the backend — the
+  whole restic snapshot tier + repo stats + snapshot history + restic-password UI is dead. That's a
+  **backups-page de-priv rebuild** (a design slice: what the page shows in the app-data-only model), well
+  beyond the CrossDrive cleanup this spec scoped (the spec listed "backups.html (5)" = the CrossDrive refs,
+  which I removed). `/backups` was already 500'ing before this task. **Recommend it as the next slice.**
 
 ## Notes
-- The traefik **dashboard route** (`dynamic/dashboard.yml`) remains deferred (needs a generated
-  basic-auth hash) — routing/cert for filebrowser + controller work without it.
-- HTTP-01 path (ACME email but no CF token) can't issue wildcards → falls back to a plain TLS route
-  (self-signed). The felhom production always uses Cloudflare DNS-01, so the wildcard path is the norm.
+- No agent disk-subsystem or gate changes; the only agent change is the read-only `durable_id` exposure
+  (v0.22.0) the user approved (without it the de-privileged controller can't learn the fs UUID `assign`
+  needs). Golden rebaked with controller 0.43.0 so fresh provisions get the rebuilt UI.
