# REPORT — v0.43.0: rebuilt storage management (guided init/attach/eject on the agent disk model)

**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

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**.

- **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.

## 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 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
- 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.
