# Felhom Hub — Changelog

## v0.27.0 — Hosts page: read-only fleet view (audit F-M1) (2026-07-01)

Resolves audit finding **F-M1**: the agent enrolls as a *host* and the hub stores rich host state
(identity, agent version, guests, storage targets with SMART, DR/escrow, staleness) and alerts on it —
but the whole host domain was **invisible in the GUI** (email-only). Adds a **Hosts** nav section — a
fleet list + a per-host detail page. **Read-only** (GET only, no host actions/mutation routes): this
surfaces state the way the pull/desired-state model demands; it does not reintroduce inbound control
(retired in v0.26.0).

- **New store reader `ListGuestsForHost(hostID)` (`internal/store/store.go`).** `SELECT … FROM guests
  WHERE host_id = ? ORDER BY vmid`, via a new `scanGuest` helper over `guestRealitySelectCols` — the
  reality columns only. It deliberately **omits the secret/inert columns** (`api_key`,
  `desired_spec_json`), so the read-only view can never surface them. Returns `[]` (never nil-error) on
  no guests. (There was previously no guests *reader* — only `UpsertGuestFromReport`.)
- **New handlers (`internal/web/hosts.go`).**
  - `handleHostsList` — `ListHosts` + a per-host status badge from `hostStatus()` (which reuses
    `s.staleThreshold` — the **same** thresholds as the `HostStalenessChecker`: stale after the
    threshold, down at 2× — so the badge agrees with the alerting) + per-host guest counts
    (`ListGuestsForHost`) + vitals parsed from `GetLatestHostReportJSON` + worst storage fill grouped
    from `GetHostStorageTargets`.
  - `handleHostDetail` — `GetHost` (404 if absent) + `ListGuestsForHost` + rich storage targets (role,
    state, fill %, thin-pool, SMART health/temp/wear parsed from the latest report body) + vitals +
    `GetHostDRBundle`/`GetHostEscrow` **presence booleans only** (never the opaque blobs). Nil/missing
    (no report, no guests, no storage, no DR) render empty states — never a panic.
- **New templates `hosts.html` + `host_detail.html`** (existing dark operator-console styling reused —
  `data-table`, `status-badge-*`, `info-grid`, `empty-state`; no restyle). A no-report host shows a
  STALE/NO-REPORT badge and "waiting for first report".
- **Nav:** added the `Hosts` link (between Apps and Configuration) to every page's `<nav>` (the nav is
  duplicated per page, not a shared partial) + the new `timeAgoPtr` template helper for `*time.Time`.
- **Routes (`internal/web/server.go`):** `GET /hosts` (+ `/hosts/`) → list, `GET /hosts/{id}` → detail,
  modelled on the `/apps` pair. GET only.
- **Tests:** `ListGuestsForHost` (none→empty, multiple→vmid-ordered, secret column not surfaced); the
  list handler (N rows, ONLINE + NO-REPORT badges, worst-fill, no action buttons); the detail handler
  (guests + storage + SMART + DR present, customer cross-link, **no-secret assertion** that the host
  `api_key` is absent from the rendered body, no buttons); unknown host → 404; no-report host renders
  the waiting state. `hostStatus` band mapping unit-tested (pending/ok/stale/down).
- **Remaining audit follow-ups (not this slice):** controller-side geo intent sync; a read-only
  reported-vs-desired "Show Diff"; the cosmetic `controllerURL` cleanup in `configs.go`.

## v0.26.0 — pull-based config delivery + retire the inbound GUI controls (2026-06-30)

Closes audit `documentation/audits/AUDIT-hub-gui-2026-06-30.md` F-S1/F-S4 + the dead-template findings,
and replaces the never-inbound-violating "Push Config" with a pull-based config-refresh that rides the
report ACK (companion controller change: felhom-controller v0.94.0).

- **Config delivery is now pull-based (`internal/store/store.go`, `internal/api/handler.go`).** New
  `customer_configs.config_version` column — a **stored counter** (NOT a hash of the rendered YAML;
  `configgen` emits a fresh `web.session_secret` + timestamp every call, so a content hash would change
  spuriously). `SaveCustomerConfig` **bumps it on every save** (new rows seed at 1, updates increment) —
  the one path that changes the generated `controller.yaml` (identity + the `config_json` overrides). The
  floor, block/unblock, and retrieval-password regen deliberately do NOT bump it. The report ACK
  (`handleReport`) now advertises `config_version` beside `min_controller_version`/`latest_version`; the
  controller compares it to its last-applied version and re-pulls + self-restarts on a change. Omitted for
  report-only (no-config) customers, so an old controller is unaffected.
- **Retired the five inbound (hub→box) controls** that violated the never-inbound posture
  (`01-topology-and-trust.md:11`) and were broken behind the box's CF tunnel/NAT:
  - **Trigger Update** — handler + route deleted; controller updates are agent-driven (the version floor).
  - **Push Config** — handler + route deleted; replaced by the pull-based config-refresh above.
  - **Pull Config** — handler + route deleted.
  - **Show Diff** (`handleConfigDiff` + the `compareYAMLValues`/`flattenYAML`/`maskSensitive` helpers) —
    deleted, along with the now-dead `ConfigSyncStatus`/`ConfigDiffCount` plumbing.
  - **Geo-disable** — KEEPS its legitimate hub→Cloudflare WAF-rule removal (`RemoveGeoRules`); the
    secondary inbound `notifyControllerGeoDisable` is deleted. After this, `grep client.Do
    internal/web/` has **zero** ControllerURL targets (only Gitea registry/template fetches remain; the
    ControllerURL is still shown as a display-only link).
- **GUI staleness (F-S1) + dead templates:** the customer page's Setup Commands now show the Proxmox
  Day-0 host bootstrap (`sudo ./felhom-host-install.sh --customer-id <id>`, passphrase at the no-echo
  prompt) instead of the pre-Proxmox `docker-setup.sh`; Option 2 relabelled "Manual config fetch (debug
  only)". Deleted the orphaned `customer.html` + `config_detail.html` (rendered by nothing; `/configs/{id}`
  redirects to `/customers/{id}`).
- **Audit doc (deferred line):** the GUI audit `documentation/audits/AUDIT-hub-gui-2026-06-30.md` (committed
  `e51e03b`) is the grounding for the above; its F-S1/F-S4 + dead-template findings are now resolved. Open
  follow-ups noted there remain: the Hosts page (F-M1), controller-side geo intent sync, and Show-Diff
  could return later as a read-only-vs-reported view.
- Tests: store `config_version` bump (create=1, edits increment, per-customer independent) + the
  no-bump red-proof; ACK carries `config_version` and omits it for report-only customers + the no-bump
  red-proof. `go build/vet/test ./...` green.

## v0.25.0 — per-storage worst-fill alerting (StorageFillChecker) (2026-06-30)

Generalizes the host-root disk alert (v0.23.0) to ANY reported storage target — so a dedicated
dump/backup volume, data drive, lvmthin pool, or PBS datastore filling toward failure pages the operator
with the storage named, even when host root itself is fine.

- **`internal/monitor/storage_fill.go` (NEW) — `StorageFillChecker`.** A per-target mirror of
  `HostDiskChecker` on the same 60s sweep: born/persistent (already-breached `(host,target)` keys left
  UNSEEDED → first `Check` emits), escalation-only emit, recovery re-arm, the dispatcher's 1h cooldown.
  State is keyed per **(host, target)** so targets alert independently. Emits distinct
  `storage_fill_warning` / `storage_fill_critical` at the **natural `critical` severity** (exercises the
  v0.24.0 dispatcher fix with a second real caller). Default thresholds 90/95, hub-config overridable
  (`alerting.storage_fill_warn_percent` / `_crit_percent`), independent of the host-root thresholds.
- **Root excluded (no double-alert):** the host root-backed builtin (`Type=="local"`, or a target mounted
  at `/`) is skipped — `HostDiskChecker` owns root. So a root-backed vzdump dump is one alert (from
  host_disk), and storage_fill uniquely covers OFF-root storage.
- **`internal/store/store.go`:** `GetHostStorageTargets()` + `HostStorageTargetRow` — parses
  `report_json.storage_targets[]` of each host's latest report (percent = `used_fraction`×100); modeled on
  `GetHostDiskUsage`, no denorm column / migration.
- **`internal/notify/templates.go` + `internal/api/handler.go`:** Hungarian templates + allowlist entries
  for `storage_fill_warning` / `storage_fill_critical`.
- **`cmd/hub/main.go`:** register `storageFillChecker` on the 60s tick beside `HostDiskChecker`.
- Tests: per-target bands (independent warn/escalate/recover/re-arm), **born/persistent companion red-proof**
  (a seed-all model stays silent on the born-breach), **root-exclusion companion** (without the exclusion a
  root target IS in the critical band — the exclusion is what suppresses the double-alert), severity
  `critical`, and the store parse. `go build/vet/test ./...` green.

## v0.24.0 — dispatcher routes `critical` severity (+ nil-prefs crash guard) (2026-06-30)

NAS Part A2's "Part 0": close the dispatcher's silent drop of `critical`-severity events.

- **`internal/notify/dispatcher.go` `ProcessEvent`:** the severity gate was `severity != "warning" &&
  severity != "error"` → a `critical` event was **silently dropped** (never emailed). Now routes
  **warning / error / critical** (`severityNotifies`); `info` stays an intentional non-notify; any
  **unrecognized** severity is **logged** (`[WARN] Dispatcher: unrecognized severity …`), never silently
  dropped. Verified safe first: no controller event emits `critical` (all are info/warning/error) and the
  hub's only would-be `critical` emitter is `host_disk` — so no surprise alert volume.
- **`internal/monitor/host_disk.go`:** `host_disk_critical` now emits its **natural `critical` severity**
  (was forced to `error` to survive the old gate); `FormatOperatorEmail` styles `critical` 🔴 like `error`.
- **Latent crash guard:** `processCustomer` dereferenced `GetNotificationPrefs`, which returns `(nil, nil)`
  for a customer with no notification row — an event for such a customer would **panic the dispatcher
  goroutine and crash the hub**. Now guards `prefs == nil` before use.
- **Seam:** `sendEmailFn` field (defaults to the Resend sender) so routing is unit-tested without real HTTP.
- Tests: `severityNotifies` (warning/error/critical notify; info/unknown don't) + **companion red-proof**
  (the pre-fix `warning||error` predicate drops `critical`); ProcessEvent routes `critical` to the operator;
  an unknown severity is logged not dropped; `info` is silent and not mis-logged. `go build/vet/test ./...`
  green.

## v0.23.0 — host root-disk pressure monitoring + alert (2026-06-30)

Closes the silent-failure gap behind the felhom-pve incident: a Proxmox host root fs filling up (vzdump
piling under `/var/lib/vz/dump`) went unnoticed because nothing alerted on the HOST root `disk_percent` the
agent already reports. New hub-side checker on the existing 60s sweep.

- **`internal/monitor/host_disk.go` (NEW) — `HostDiskChecker`.** A sibling of `HostCapabilityChecker` /
  `HostLeafChecker`: reads each host's latest root-fs `disk_percent` (`store.GetHostDiskUsage`) and emits an
  operator alert on a warning (default **90%**) or critical (default **95%**) crossing. Rank-based bands
  (ok→warning→critical) so an escalation always alerts and a de-escalation/recovery re-arms silently.
  - **Born/persistent (the F2 lesson):** a disk ALREADY over threshold when the hub/checker (re)starts
    alerts on **cycle 1** — seeding leaves already-breached hosts UNSEEDED so the first `Check` emits (a
    transition-only design would stay silent forever on a persistently-full disk). The dispatcher's 1h
    operator cooldown dedups re-emits across a hub restart.
  - **Distinct event types** `host_disk_warning` / `host_disk_critical` — NOT the controller's GUEST
    `disk_warning`/`disk_critical` (the guest cgroup view), so the host and guest alerts never dedup or mask
    each other.
  - **Severity:** warning band → `warning`; **critical band → `error`** (NOT `"critical"`). The dispatcher
    only routes `warning`/`error` severities — a `"critical"` severity would be silently dropped — so the
    critical band maps to `error` (and the operator email's 🔴). (Deviation from the task's stated
    "critical → critical", made to match the live dispatcher.)
  - **Thresholds** are hub-config overridable (`alerting.host_disk_warn_percent` /
    `host_disk_crit_percent`, seed-only); an unset/invalid/misordered config falls back to 90/95
    (`normalizeDiskThresholds`) so a typo can never silence or invert the alert.
- **`internal/store/store.go`:** `GetHostDiskUsage()` + `HostDiskRow` — latest report per host (MAX(id)),
  `disk_percent` from the denorm column + total/used bytes parsed from `report_json` (event detail). No
  schema migration.
- **`internal/notify/templates.go`:** Hungarian customer templates for `host_disk_warning`/`_critical`
  (customer delivery still requires per-customer opt-in via enabled events; operator alert is the headline).
- **`internal/api/handler.go`:** `host_disk_warning`/`host_disk_critical` added to `allowedEventTypes`.
- **`cmd/hub/main.go`:** register `hostDiskChecker` on the shared 60s tick.
- Tests: band transitions (seed/escalate/steady/recover/re-arm), severity mapping, threshold defaults, and
  the **born/persistent companion red-proof** (a seed-all/transition-only model stays silent on a
  born-breach; the real unseeded design emits). `go build/vet/test ./...` green.
- **Follow-ups (noted, not built):** per-storage `StorageTargets` worst-fill alerting (a dedicated
  dump/backup storage filling — host root `disk_percent` already covers the observed case); and the
  provisioning-side `prune-backups` retention default so a box can't refill its own root (operational fix,
  separate from this detector).

## hub-config — enable operator email alerts (config-only, no image change) (2026-06-30)

`manifests/hub.yaml` `hub-config` ConfigMap: set `notifications.operator_email: admin@felhom.eu` +
`operator_enabled: true`. The dispatcher's operator path (`Dispatcher.processOperator`) sends only when
`operatorOn && operatorEmail != ""`; without these it returned early, so the self-health pipeline
(probe → report → checker → dispatch) stopped one hop short of the inbox (the TESTRUN's unproven hop).
**No hub image change** (live tag stays v0.22.1) — ConfigMap edit + pod restart to reload.
- **Proven end-to-end (2026-06-30):** a real capability-degrade alert produced
  `[INFO] Operator email sent for demo-felhom/agent_capability_degraded` (the send-success line that
  never fired while the path was gated); the customer path (`POST /api/v1/notify` `event_type:test`) sent
  to the customer address via the same `sendEmail` → Resend. See
  `documentation/audits/TESTRUN-fullstack-2026-06-29.md` ("Findings closed", Part A). Operator email is not
  a secret; the Resend key stays injected from `Secret/resend-api`.

## v0.22.1 — wire HostLeafChecker into the monitor loop (v0.22.0 missed the wiring) (2026-06-29)

The v0.22.0 commit added `HostLeafChecker` but the `cmd/hub/main.go` goroutine edit never applied, so
the checker was never started. The live test caught it (a leaf regen produced no `host_leaf_changed`,
only the controller's complementary `agent_channel_pin_mismatch`). Now started on the 60s sweep next to
the staleness/capability checkers. No other change.


## v0.22.0 — proactive agent re-key detection: HostLeafChecker (host_leaf_changed) (2026-06-29)

Companion to felhom-agent v0.48.0 (which now reports its served local-API leaf fp). The hub watches
each host's leaf fingerprint and raises an operator alert when it **changes** (an agent re-key) —
proactive, fleet-wide, independent of any controller's channel-health check. The last self-health leg.

- **`monitor.HostLeafChecker` (NEW):** sibling of `HostCapabilityChecker`. Trust-on-first-report — the
  first fp per host is the baseline; a later change emits **`host_leaf_changed`** (operator, English;
  details carry old+new fp) and advances the baseline. First-obs seeds silently (a "change" needs a
  prior value, so no F2 issue). An empty reported fp (pre-v0.48.0 / local-API-disabled) is unknown —
  never seeds, never alerts, never overwrites a baseline. Customer-blocked hosts dropped; unseen pruned.
  Runs on the existing 60s sweep. **KNOWN LIMITATION (documented):** trust-on-first-report can't detect
  a re-key that happened before the hub's first report — but the controller channel-check catches the
  downstream pin mismatch, so this is defense-in-depth.
- **`store.GetHostLeafFingerprints` (NEW):** latest reported fp per host, parsed from `report_json`
  (mirrors `GetHostCapabilities` — `MAX(id)`, **no schema migration**).
- **No allowlist change:** `host_leaf_changed` is hub-GENERATED (via `SaveEvent` + `dispatcher.ProcessEvent`),
  not controller-pushed, so it bypasses the `/api/v1/event` `allowedEventTypes` gate — same as the
  host_* events. The generic operator template relays it (no template change).
- Tests: change **red-proof** (A→B → one event + baseline advanced; companion: unchanged → none),
  first-obs seeds silently, change-back re-alerts, empty fp skipped, customer-blocked dropped. Cross-repo
  golden mirrors `leaf_fingerprint`. Version `0.21.0 → 0.22.0`.


## v0.21.0 — F2: alert on a host already degraded/stale at hub (re)start (2026-06-29)

Mirror of the controller's F2 fix, for the hub checkers: a host that was already **degraded**
(capability) or **stale/down** (staleness) when the hub (re)started was seeded silently and **never
alerted**. Now the constructors seed only HEALTHY hosts; an unhealthy host is left **unseeded** so the
first `Check()` emits once. The dispatcher's 1 h operator cooldown dedups the re-emit across a hub
restart (so a hub bounce doesn't re-page for an already-known issue within the window).

- `internal/monitor/host_capability.go` + `host_staleness.go`: constructor seeds only the healthy
  state; `Check()` first-obs (`oldState==""`) emits `emitTransition(…, "unknown", newState, …)` when
  the observed state isn't healthy, else seeds silently.
- Tests: born-degraded **red-proof** (host degraded at construction → unseeded → one
  `agent_capability_degraded` on first Check, no duplicate on the next); the staleness test updated to
  the F2 behavior (born-stale → unseeded → one `host_stale` on first Check). Version `0.20.0 → 0.21.0`.


## v0.20.0 — Accept controller `agent_channel_*` events (channel-health relay) (2026-06-29)

Companion to felhom-controller v0.90.0's controller→agent channel health-check. The controller pushes
classified `agent_channel_*` events to `/api/v1/event`, but the handler's `allowedEventTypes`
allowlist rejected them (HTTP 400). Added the 8 types (`pin_mismatch`, `unauthorized`, `unreachable`,
`timeout`, `misconfigured`, `construction_error`, `unknown`, `recovered`) so the operator relay works.
These are **operator-only** (not customer notification toggles, same as the host_* events); the
existing dispatcher routes them generically (no template change). Version `0.19.0 → 0.20.0`.

## v0.19.0 — Agent capability-degraded operator alert (HostCapabilityChecker) (2026-06-29)

Companion to felhom-agent v0.44.0's privileged-capability self-probe: the agent now rides a
`capabilities` snapshot on its host report (each required `sudo -n` grant: ok/degraded), and the hub
alerts the operator when a host transitions into a degraded state — closing the loop that let five
non-root-cutover regressions go undetected until user-visible breakage.

- **`monitor.HostCapabilityChecker` (NEW):** a deliberate SIBLING of `HostStalenessChecker` — same
  per-host state map (`ok`/`degraded`), seed-without-event, emit-only-on-transition shape. A host is
  `degraded` iff its latest report has any **Critical** capability with `status:"degraded"`;
  non-critical degradations ride the report but never alert. Runs on the existing 60s sweep next to
  the staleness checkers.
- **Events:** `agent_capability_degraded` (warning) on ok→degraded, naming the degraded capabilities
  + gated features in the message and details JSON; `agent_capability_recovered` (info) on
  degraded→ok. Routed through the existing `Dispatcher.ProcessEvent` — **operator-only** (the type
  is not a customer notification toggle, same as `host_stale`) with the standard 1 h operator
  cooldown (no per-cycle re-alert).
- **`store.GetHostCapabilities` (NEW):** reads the capability snapshot from the latest host-report's
  `report_json` per host (keyed on `MAX(id)` — within-second `received_at` ties would otherwise
  return multiple rows). **No schema migration** — the array rides the existing report body. A
  pre-v0.44.0 agent (no `capabilities`) reads as `ok`, so an old agent can't trip a false alert.
- Cross-repo `host-report.golden.json` mirrors the new `capabilities: []` field (byte-identical with
  the agent copy). Version `0.18.0 → 0.19.0`.

## v0.18.0 — App-email passthrough: POST /api/v1/mail → Resend SMTP (2026-06-29)

The hub can now relay a customer box's outbound app email to Resend, re-emitting the raw MIME
**unchanged** over SMTP. This is the hub leg of the app-email relay (apps → on-box shim → hub →
Resend); the Resend key stays hub-side. Implements `documentation/audits/SPIKE-smtp-app-relay-2026-06-28.md`.

- **New `internal/mailrelay/relay.go`:** `ResendSMTP` (a `Sender`) — STARTTLS to `smtp.resend.com:587`,
  `AUTH LOGIN resend/<key>` (a small `net/smtp.Auth` LOGIN impl; stdlib ships PlainAuth only), then raw
  `MAIL`/`RCPT`/`DATA`. **Raw passthrough** — NOT the `internal/notify` Resend **HTTP-API** path, which is
  unchanged for the hub's own structured alerts and silently drops inline CID images (spike §4). No new
  external dependency (stdlib `net/smtp`).
- **New `POST /api/v1/mail`** (`internal/api/mail.go`): authenticates the box (`checkAuthCustomer`), enforces
  the **From-header** domain allowlist (backstop; reject 403), applies a **per-customer in-memory token-bucket
  rate limit** (default 30/min → 429 so one box can't drain the shared Resend quota), then passes the raw
  bytes through to Resend. Success→200, Resend failure→502 (the box's shim maps that to the app).
- **Config:** new `mail` section (`per_customer_per_minute`, `from_domains`); wired in `cmd/hub/main.go` only
  when a Resend key is present (else the endpoint returns 503). The existing `notify/dispatcher.go` alert path
  is untouched.
- **Tests:** passthrough byte-equality (raw bytes reach the sender unchanged, not parsed), From-reject +
  companion red-proof, per-customer rate-limit + isolation + companion, send-failure→502, 401/503/400 paths,
  token-bucket unit (injected clock), LOGIN auth + From-domain parsing.

## v0.17.0 — Resend key sourced from a Secret, out of git (2026-06-29)

Resend rotation + de-git hygiene. The hub's Resend API key was committed in plaintext in
`manifests/hub.yaml`'s `hub-config` ConfigMap; it is now sourced from an out-of-band Kubernetes
Secret (`resend-api`) and never lives in git.

- **`cmd/hub/main.go`:** new `RESEND_API_KEY` env override for `notifications.resend_api_key`, mirroring
  the existing `REGISTRY_TOKEN` / `DEFAULT_MIN_CONTROLLER_VERSION` k8s-Secret override pattern. When set,
  it wins over the (now empty) ConfigMap field. No behaviour change when unset.
- The committed ConfigMap `resend_api_key` is now an empty placeholder pointing at
  `documentation/runbooks/secrets.md`; the live value is injected from `Secret/resend-api` via env.
- Part of the Resend key rotation: the previously-exposed send-scoped key was rotated; the new key lives
  only in the out-of-band store and `Secret/resend-api` (created imperatively, never committed). See the
  secrets runbook. No secret value appears in this repo.

## v0.16.0 — Day-0 artifact manifest (hub-vouched agent + golden checksums) (2026-06-28)

The hub now serves a passphrase-authed **artifact manifest** so the host-bootstrap script can
**fetch-then-verify** the agent binary + golden archive from Gitea before installing them. The hub is
the checksum **trust root** — a different root than Gitea (which only stores the bytes). Part of the
BUNDLE slice that lets a fresh PVE box self-install the agent (no more manual binary/unit step).

- **`store.go`:** `ArtifactManifest{agent_version, agent_sha256, golden_version, golden_sha256}` with
  `Get/SetArtifactManifest`, persisted as four discrete rows in the existing `hub_settings` key/value
  table (no schema change — same mechanism as the controller-version floor; survives restarts; partial
  sets round-trip). Added generic `getSetting/setSetting` helpers.
- **`handler.go`:** new `GET /api/v1/artifacts/{customer_id}` — auth mirrors `handleConfigRetrieve`
  EXACTLY (`X-Retrieval-Password`, 404-then-401 order, constant-time compare). Returns
  `{"agent":{version,sha256},"golden":{version,sha256}}`. An unset manifest returns **200 with empty
  fields** (not an error) so the script falls back to the local golden / fails clearly on a missing
  binary. v0.16.0 returns the GLOBAL current set for every customer (per-customer pinning is a future
  hook).
- **`configs.go` + `configs.html` (operator UI):** a "Day-0 artifacts — agent & golden" card beside the
  managed-update floor controls, with version + sha256 fields for each artifact. `POST /configs/artifacts`
  (CSRF-protected); versions validated as bare semver (reusing the floor validator), sha256s as 64-hex,
  blank-to-clear.
- **`main.go` (env seed):** seeds the manifest from `ARTIFACT_AGENT_VERSION` / `ARTIFACT_AGENT_SHA256` /
  `ARTIFACT_GOLDEN_VERSION` / `ARTIFACT_GOLDEN_SHA256` on startup — but only fields the DB doesn't already
  have, so a UI edit sticks across restarts. Same escape hatch the Phase-2 floor uses (the operator UI is
  password-gated).
- **Tests (`artifact_test.go`):** recorded set returned verbatim; unset → 200 empty; wrong/missing
  passphrase → 401; unknown customer → 404; store partial-set round-trip. Plus the floor-render smoke
  test updated for the new list-page data field.
- Reuse: no new auth path (passphrase, like config-retrieve + host-enroll); no new table (hub_settings);
  no new fetch credential downstream (the script reuses the config-retrieve git token).

## v0.15.0 — Phase 2 managed updates: per-customer controller-version floor (2026-06-27)

The operator can now set a **minimum controller version** (FLOOR) — per-customer, defaulting to a
**global** floor — and any box below it **auto-updates** to the floor on its next report (no customer
action). The customer "update to latest" button is unchanged (latest, opt-in); the floor is the
operator's enforced minimum and the **auto-target** (controlled rollout: the operator raises the floor).

- **`store.go`:**
  - `customer_configs` gains `min_controller_version TEXT NOT NULL DEFAULT ''` (per-customer override).
  - New `hub_settings(key,value)` table holds the operator-set **global** floor (survives restarts).
  - Global default fallback `SetDefaultMinControllerVersion` (config/env `DEFAULT_MIN_CONTROLLER_VERSION`).
  - `EffectiveMinControllerVersion(customerID)` = per-customer override if non-empty, else global
    (hub_settings → config default), else "". Plus `Set/GetGlobalMinControllerVersion`,
    `SetMinControllerVersion`.
- **`handler.go` (`handleReport`):** the controller report ACK (previously just `{status, customer_blocked}`)
  now also returns `{min_controller_version: <effective floor>, latest_version: <registry latest>}`. Both
  omitted when empty, so old controllers / unconfigured hubs behave exactly as before. New
  `SetLatestVersionProvider` wires the registry `VersionChecker` (nil-safe).
- **`configs.go` + templates (operator UI, English):** the Customers list shows a **Floor** column
  (effective floor, "override" tag, below-floor ● marker) + a **global floor** editor; each customer page
  shows the effective/global floor, below-floor status, and a **per-customer override** form. Routes
  `POST /configs/global-floor` and `POST /customers/{id}/floor` (CSRF-protected; X.Y.Z or blank-to-clear).
- **`main.go`:** seeds the default floor from config/env; wires the latest-version provider.
- **Tests:** effective-floor resolution (override beats global; empty when unset; DB-beats-default;
  preserved across save); report ACK carries effective floor + latest + omits when unset; template render
  smoke. **Companion red-proof:** breaking `EffectiveMinControllerVersion` to return the global when an
  override is set makes the override-precedence store test AND the ACK test FAIL (verified, then restored).
- Reuse: rides the existing report cycle (no new endpoint); the swap itself is the controller's Phase 1
  flow + the agent — untouched here.

## v0.14.0 — Passphrase-authed host enrollment (Day-0 option C) (2026-06-26)

Adds the single-secret Day-0 host-enrollment path proven in
`documentation/audits/SPIKE-day0-firstboot-handshake-2026-06-26.md` (option C). The operator /
host-bootstrap script now carries **only the customer's retrieval passphrase** — the global operator
key never enters the field deploy path.

- **New endpoint `POST /api/v1/host-enroll`** (`internal/api/handler.go`, `handleHostEnroll`):
  passphrase-authed (`X-Retrieval-Password` header, body `{customer_id}`), returns
  `{host_id, api_key}`. **Mint-once-reuse** — mints on first call (`201`), returns the existing
  credential byte-for-byte on every subsequent call (`200`), so re-running the bootstrap never orphans
  a running agent's key. Auth is checked **before** any mint (a wrong passphrase never writes a row):
  wrong/missing passphrase → `401`, unknown customer → `404`, missing `customer_id` → `400`. Mirrors
  `handleConfigRetrieve`'s auth pattern + `handleAdminCreateHost`'s mint block.
- **New store method `Store.GetHostByCustomer`** (`internal/store/store.go`): `SELECT … FROM hosts
  WHERE customer_id = ? ORDER BY updated_at DESC LIMIT 1` (uses `idx_hosts_customer`), nil-on-not-found.
  Backs the reuse lookup. >1 host for a customer (not expected in Day-0) → most-recent wins, never a
  duplicate mint.
- **Unchanged & deliberately untouched:** `GET /api/v1/config/{id}` (controller pull — same raw-YAML
  body) and `POST /api/v1/admin/hosts` (global-key operator escape hatch, still PROVISIONAL pending the
  cutover lock-down).
- Tests: `internal/api/host_enroll_test.go` (mint/reuse/401-no-mint/404/400, +5) and a
  `GetHostByCustomer` store test (+1); companion red-proof confirmed an always-mint variant fails the
  reuse assertion.

## v0.13.1 — DR recipe v1 drive-shape sync: test-data + regression guard only (2026-06-16)

**No behavior change — redeploy optional.** Tracks the agent's v0.39.0 v1 host-half drive shape (which
dropped `role` + `restic_repo_coord` from `drives[]`). Because the hub reads drives as `json.RawMessage`
(verbatim passthrough), no store/handler/struct change was needed — only test-data + a regression guard.

- `internal/store/testdata/dr-recipe.golden.json` + the `drHostHalf` test fixture: dropped the `role`
  key from `drives[0]` to match the v1 shape the agent now emits.
- `internal/api/testdata/host-report.golden.json`: re-synced to be **byte-identical** with the agent's
  `internal/hub/testdata/host-report.golden.json` (sha256 `57f2a5e7…18b2f2b5`). The hub copy previously
  lacked the `dr_recipe` section entirely; it is now a verbatim copy, so the cross-repo golden truly
  matches and POSTing it through `/host-report` exercises the `SaveDRRecipeHostHalf` ingest path.
- New `TestAssembleDRRecipe_V1DriveShape` — the regression guard: a stored host half whose `drives[]`
  carry NEITHER dropped field but WHICH HAS a `pbs` block assembles cleanly (pbs carried through, drives
  passed through verbatim, neither `role` nor `restic_repo_coord` present). Demonstrated to FAIL when the
  fixture re-adds `role`, then reverted.

## v0.13.0 — DR recipe: assemble + store + view the secret-free reconstruction recipe (2026-06-16)

**DR recipe slice (hub half)** — the assemble-store-view side of the secret-free reconstruction recipe
(`documentation/audits/SPIKE-dr-recipe-2026-06-16.md`). The hub receives two additive halves via the
existing report paths — the agent's storage/guest/PBS half (on the host-report) and the controller's
customer/apps half (on the controller report) — and assembles them into one operator-readable recipe per
customer. This is the clean inverse of the retired infra-backup: same "re-provision plan" goal, but
PLAINTEXT-at-rest is *correct* because the recipe has zero secrets.

- **Store** (`internal/store/dr_recipe.go`): a DEDICATED `dr_recipe` table (NOT `host_escrow`, NOT the
  dropped `infra_backup*` tables) keyed by `customer_id`, holding `host_half_json` + `app_half_json` +
  `recipe_version` + `host_id`. `SaveDRRecipeHostHalf` / `SaveDRRecipeAppHalf` each upsert their half and
  PRESERVE the other (last-write-wins per half). `AssembleDRRecipe` stitches the two into an
  `AssembledRecipe{recipe_version, customer, guests, pbs, drives, pve_storage, apps}` — sub-sections pass
  through as `json.RawMessage` (verbatim), **ignore-unknown** at the top level and version-skew tolerant
  (`recipe_version` = max of the two halves) for forward-compat across the three repos.
- **Ingest** (`internal/api/handler.go`): `handleHostReport` persists the `dr_recipe` host-half (keyed by
  the host's customer); `handleReport` persists the `dr_recipe` app-half (keyed by `customer_id`) —
  mirroring the `app_telemetry` pattern, backward-compatible (old agents/controllers omit the field), and
  never fatal to the heartbeat.
- **View** (`internal/web/dr_recipe.go` + customer page): a DR-recipe panel on the customer detail page
  (which half has landed + last-updated) with a **Download recipe (JSON)** link →
  `GET /customers/{id}/dr-recipe.json` serves the assembled recipe (operator dashboard-auth, pretty JSON,
  `Content-Disposition` attachment). No decrypt, nothing to redact.
- Tests: `TestDRRecipe_StoreRoundTrip` (each half preserves the other), `TestAssembleDRRecipe_MatchesGolden`
  (the assembled wire shape pinned in `testdata/dr-recipe.golden.json`),
  `TestAssembleDRRecipe_IgnoreUnknownAndVersionSkew` (a forward-compat half still assembles; version = max),
  `TestAssembleDRRecipe_PartialHalves` (one half present), `TestAssembleDRRecipe_NoSecrets` (defense-in-depth
  credential-key sweep). Pairs with felhom-agent v0.38.0 + felhom-controller v0.73.0.

## v0.12.0 — retire Infra Backup + purge its plaintext secrets + fix the daily backup-deadline email (2026-06-16)

Phase-1 of the Infra Backup retirement (per `documentation/audits/SPIKE-infra-backup-2026-06-15.md`).
The mechanism had been dead since slice 8C, yet the hub still stored each version as a **plaintext
JSON blob at rest** containing the customer's app-secret encryption key, restic password, and
Cloudflare tokens — a zero-knowledge violation. Its absence was also the root cause of the daily
`expected_backup_missed` false-alarm email.

### Changed
- **Backup-deadline check repointed to PBS freshness.** `monitor.CheckBackupDeadlines` no longer
  looks for a `backup_completed` event (no component emits it anymore — the disk-tier backup moved to
  the agent in slice 8C, so the check fired daily for every healthy customer). It now reads the
  customer's **latest agent host-report** and raises `expected_backup_missed` only on positive
  evidence: no PBS snapshot / successful vzdump at all, the newest backup older than **26h**, or the
  newest PBS snapshot's `verify_state == "failed"`. A fresh-but-not-yet-verified snapshot is **not** a
  failure (PBS verifies on its own cadence) — alarming on it would just re-create the false alarm. The
  **db-dump half is unchanged** (the in-guest controller still emits `db_dump_completed`). A customer
  with **no host-report** (legacy/defunct) gets no backup alarm here — liveness is the
  host-staleness checker's job. New store accessor `GetLatestHostReportJSON`. Tests:
  `internal/monitor/deadline_test.go` (fresh+verified→quiet, stale→alarm, failed-verify→alarm,
  no-report→quiet, db-dump half preserved, plus a pure `assessBackupFreshness` table). The
  fresh+verified→quiet test is the **companion**: it fails against the old event-based check.

### Removed
- **The Infra Backup feature**: ingest endpoint `POST /api/v1/infra-backup`, getters
  `GET /api/v1/infra-backup/{id}[/versions]` and their handlers; store methods
  `SaveInfraBackup` / `GetInfraBackup` / `GetInfraBackupByID` / `GetInfraBackupMeta` /
  `ListInfraBackupVersions` / `pruneInfraBackups` + the `InfraBackupMeta` / `InfraBackupVersion`
  types; the operator **"Infra Backup" panel** (`customer_unified.html`, `customer.html`). The
  `GET /api/v1/recovery/{id}` endpoint is kept but now returns **only** the generated `config_yaml`
  (no infra-backup payload). The customer-page **config-drift badge** that diffed against the stored
  controller.yaml is hidden (its at-rest source is gone); the live **"Show Diff"** path is unaffected.

### Security / migration
- **Plaintext secret purge.** `migrate()` now `DROP`s `infra_backup_versions` + `infra_backups` and
  runs **`VACUUM`** (+ `wal_checkpoint(TRUNCATE)`) so the freed pages holding the plaintext keys/
  tokens are **physically reclaimed**, not merely delinked. Gated on table existence so normal
  restarts don't pay the VACUUM cost.
- **Out of scope (flagged for the operator):** the exposed Cloudflare / hub / session credentials in
  the dropped blobs remain valid until rotated (operator step). Separately, the legacy `reports`
  table holds thousands of historical rows with a plaintext `restic_password` value from old
  controller versions — a distinct leak, not purged here (the live controller no longer sends it).

## v0.11.0 — slice 10D: DR capstone — recovery mode + re-enroll + directive serving (2026-06-10)

The hub half of the slice-10 DR capstone (closes slice 10). The hub ORCHESTRATES recovery but holds
**no usable secret and no Cloudflare write-power**: the escrow blobs it serves are opaque (need `R`,
which the hub never has), and the destructive tunnel/PBS rotation is the **operator's** step from a
trusted environment. A compromised hub can at most hand out opaque blobs + rotate/revoke its own
per-host credential — it cannot hijack a customer's tunnel.

### Added
- **`PUT /admin/hosts/{id}/recovery-mode`** (global key) — arm recovery mode with a bounded TTL
  (`ttl_seconds`, clamped [60s, 4h], default 30m → **auto-expires**); **`DELETE`** to disable. The
  restore directive + re-enroll are served ONLY while recovery mode is active.
- **`POST /hosts/{id}/re-enroll`** — gated ONLY on recovery mode (the lost box has no old key; the
  operator armed recovery mode after out-of-band validation). Rotates the host's API key to the new
  box's key (**the old box's hub access is revoked instantly**) and returns the DR directive + the two
  **opaque** escrow blobs. Without recovery mode → 403. Zero-knowledge: even a wrongful re-enroll in
  the window leaks nothing recoverable (the blobs need `R`).
- **`GET /hosts/{id}/restore-directive`** (re-enrolled key, recovery-gated) — re-fetch the directive.
- **Store/escrow**: `hosts.recovery_mode_until` (additive); `host_escrow.identity_blob` +
  `directive_json` (the age-wrapped identity blob + non-secret directive, stored alongside the
  K-escrow). Methods: `SetRecoveryMode`/`ClearRecoveryMode`, `RotateHostAPIKey`, `SaveHostDRBundle`/
  `GetHostDRBundle`. The slice-7 escrow upload (`PUT /hosts/{id}/escrow`) now also accepts
  `identity_blob_b64` + `directive` (additive).

### Not built (by design — the locked rotation model)
- **No Cloudflare write-credential in the hub.** The operator deletes the stale tunnel connector +
  rotates the tunnel/PBS token from their trusted environment (a documented procedure / future small
  operator CLI). The hub may optionally hold a read-only CF token to surface connector state.

### Tests
- re-enroll refused without recovery mode (403); recovery-mode arm is global-key-only; re-enroll
  **rotates + revokes** (old key → 401, new key → 200); directive served only in recovery mode +
  **expires**; clear disables re-enroll.

## v0.10.0 — slice 10B: signed-op job completion (clear-job) (2026-06-10)

The hub half of slice 10B is small by design — the hub stores + serves the operator-signed blobs
**opaquely** (it holds no signing key and can neither forge nor open them; the agent verifies +
executes). 10B adds the missing **completion** path so a processed job leaves the queue.

### Added
- **`DELETE /api/v1/hosts/{host_id}/jobs/{job_id}`** (per-host key, **self-scoped**; the global key
  may clear any) — the agent calls it after executing OR terminally rejecting a job. Idempotent
  (clearing an absent job is a clean 200). Store: `DeleteSignedJob`.

### Unchanged (already in 10A, reused by 10B)
- `POST /admin/hosts/{id}/jobs` (operator enqueues the signed blob), `GET /hosts/{id}/jobs` (the
  agent fetches), and the `has_signed_ops` envelope flag. The signed blob stays opaque on the wire
  (a base64 `{op_blob_b64, sig_armored}` envelope the agent parses) — **no jobs-wire golden change**.

### Tests
- `DELETE …/jobs/{id}` is self-scoped (host A cannot clear host B's job → 403) and idempotent.

## v0.9.0 — slice 10A: desired-state serving + signed-jobs queue (the "Down" channel) (2026-06-10)

The hub half of slice 10A: the hub now **serves operator intent** down to already-authenticated
hosts. The control envelope (the host-report response) stops returning placeholder
`desired_generation:0 / has_signed_ops:false` and carries the host's **real** generation + a
signed-jobs flag — the cheap change-notification the agent (v0.15.0) acts on. The heavy
desired-state moves only on a dedicated, self-scoped fetch.

### Added
- **`PUT /api/v1/admin/hosts/{host_id}/desired-state`** (global/operator key only) — sets a host's
  desired-state and **atomically bumps `desired_generation`**. The body is JSON the hub stores +
  serves **opaquely** (it validates only that it is well-formed JSON; the agent/CLI owns the
  schema). Unknown host → 404; malformed JSON → 400. Minimal admin path; rich editing UX is later.
- **`GET /api/v1/hosts/{host_id}/desired-state`** (per-host key, **self-scoped** — a host reads
  only its own; the global key may read any) — returns `{generation, desired_state}`. The agent
  fetches it when the envelope's generation advances past its cache.
- **`GET /api/v1/hosts/{host_id}/jobs`** (per-host key, self-scoped) — serves the host's pending
  **opaque** signed-op blobs (oldest first). The hub never forged, opened, or executes them
  (verify + run is slice 10B; this only serves the queue).
- **`POST /api/v1/admin/hosts/{host_id}/jobs`** (global key only) — enqueues a pre-signed opaque
  job blob. The minimal operator path to seed the queue; the hub holds no signing key.
- **Store**: a new `signed_jobs` table (per-host opaque blob queue); `SetHostDesired` (set + bump
  generation, atomic), `EnqueueSignedJob` / `GetSignedJobs` / `CountSignedJobs`. The `hosts` table's
  previously-inert `desired_json` / `desired_generation` columns are now live.

### Changed
- The host-report **control envelope** now reports the host's actual `desired_generation` and
  `has_signed_ops` (queue non-empty), both degrading safely to their old defaults on a store error
  (a heartbeat never fails on the control channel). `poll_interval_seconds` / `blocked` unchanged.

### Tests
- admin-set bumps the generation each write + the served state reflects the latest body; admin-set
  is global-key-only (per-host → 403, malformed → 400, unknown host → 404).
- `GET /desired-state` is **self-scoped** (host A's key → host B → 403; global → any; no token → 401).
- the envelope carries the current generation + `has_signed_ops` flips on enqueue; `GET /jobs` is
  self-scoped + serves the blobs oldest-first; admin enqueue is global-key-only.
- cross-repo golden round-trip: `testdata/desired-state.golden.json` set → fetched back unchanged
  (the opaque pass-through), **byte-identical** with felhom-agent's copy.

## (no version bump) — slice 9 cross-repo wire-contract: `host.cpu_temp_c` (2026-06-10)

Slice 9 adds a nullable **`cpu_temp_c`** field to the shared `HostMetrics` wire struct (the agent's
new CPU/chassis-temperature collector). The agent's host-report carries it too, so the hub's
**cross-repo host-report golden** (`internal/api/testdata/host-report.golden.json`) was updated to
stay **byte-identical** with `felhom-agent/internal/hub/testdata/host-report.golden.json` (the
duplicated-contract discipline; manual diff confirmed identical). **No hub code change** — the full
report_json already persists the field verbatim, and the hub does not surface CPU temp on the
operator dashboard yet (an optional later freebie). The golden-contract test (`host_test.go`) still
passes (the host parse-struct ignores the extra key).

## v0.8.0 — opaque PBS recovery-code escrow storage (slice 7, doc 03 §8a) (2026-06-10)

Hub half of slice-7 close-out: store the agent's **opaque** `R`-wrapped PBS-key escrow blob. The
default posture is zero-knowledge — the hub holds ciphertext it **cannot open** (it has no recovery
code; there is no decrypt path). Pairs with felhom-agent v0.9.0 (escrow creation). Consumption /
restore-mode serving is slice 10.

### Added
- **`PUT /api/v1/hosts/{host_id}/escrow`** — authed with the **per-host key** (a host may only write
  its own escrow; the global operator key is also accepted). Body mirrors the agent's emit struct
  (`blob_b64`, `key_fingerprint`, `posture`, `created_at`). Stores the decoded **opaque bytes
  verbatim**; rotation is last-write-wins. No serving this slice.
- **`host_escrow`** table (`host_id` PK, `blob` BLOB, fingerprint/posture/created_at). Store methods
  `SaveHostEscrow` / `GetHostEscrow` (`HostEscrow`). The hub never transforms or decrypts the blob.

### Tests
- Stores the opaque blob **verbatim** (round-trips byte-identical); rotation last-write-wins;
  rejects an absent/wrong key (401) and a host writing another host's escrow (403); bad/empty
  base64 → 400; the wire-contract key-set matches the agent's emit struct.

### Security note
The hub stores ciphertext only — holding the blob does NOT let Felhom read customer data
(separation principle, doc 03 §8a). The per-host-key gate scopes writes to the owning host.

## v0.7.5 — restore-test "passed with warnings" visibility (2026-06-09)

Hub half of `TASK — Restore-test must not false-fail on benign start warnings` (Phase B). The
agent (v0.7.0) now treats a guest-start advisory like the systemd-nesting warning as a PASS
(verdict is liveness, not the start exitstatus) and carries the warning text on the wire. This
makes that visible to the operator instead of indistinguishable from a clean pass.

### Added
- `hostRestoreTest.warnings` (`[]string`) + `warnings_recognized` (`bool`) mirror fields, matching
  the agent's `hub.RestoreTest` wire contract (`omitempty`; an absent `warnings_recognized` ⇒
  `false` ⇒ treated as the louder unrecognized case — a missing flag can only over-notice).

### Changed
- Host-report ingest now surfaces a **passed** restore-test that carried warnings:
  `[INFO] restore-test passed WITH WARNINGS (recognized)` when every warning is the known-benign
  anchor, escalated to `[WARN] … UNRECOGNIZED WARNINGS` otherwise — as loud as a failed PBS
  verify, so a real restore warning can't hide behind a green pass. A FAILED restore-test still
  logs the existing `[WARN] … FAILED`.

### Tests / contract
- `restore_tests[0]` in the host-report golden gains `warnings` + `warnings_recognized`; the golden
  stays **byte-identical** with felhom-agent's copy (sha256-verified) and the bidirectional
  key-set contract test now round-trips the new keys through `hostRestoreTest`.

### Not in this slice
- No dashboard widget: the hub web layer renders only controller-report data — there is no
  host-domain dashboard surface yet (guests/storage/restore_tests/pbs_snapshots are log+persist
  only, same as the failed-PBS-verify signal). Distinct dashboard treatment lands when the
  host-domain dashboard does (slice 10). The operator signal this slice is the log line.

## v0.7.4 — ingest agent pbs_snapshots (slice 6 Phase B) (2026-06-09)

The agent's slice-6 Phase B work populates the host-report's `pbs_snapshots` (the PBS offsite
inventory + per-snapshot verify-state). This is the hub half: accept + persist them. Minimal —
the rich offsite policy is hub-owned (slice 10); this mirrors what the agent reports.

### Added
- **`hostPBSSnapshot`** mirror struct in `hostReportPayload` (`internal/api/handler.go`) —
  field-for-field with the agent's `hub.PBSSnapshot` wire contract (namespace/backup_type/
  backup_id/backup_time/size_bytes/owner/protected/encrypted/verify_state/verify_upid).
  Persisted via `report_json` (no new columns — the slice-5/6A precedent).
- **A FAILED PBS verify is logged prominently** (`[WARN]` — the loudest offsite-DR signal,
  same treatment as a failed restore-test). The `host-report` info line now counts pbs-snapshots.
- **`testdata/host-report.golden.json`** updated with a populated `pbs_snapshots[0]`, kept
  **byte-identical** with felhom-agent's copy.
- **`TestHostPBSSnapshot_GoldenContract`** — the hub half of the bidirectional key-set test.

### Notes
- Backward-compatible: an agent that omits/empties `pbs_snapshots` is accepted unchanged.

## v0.7.3 — ingest agent backups + restore_tests (slice 6 Phase A) (2026-06-09)

The agent's slice-6 work populates the host-report's `backups` + `restore_tests` (the
self-restore-test result). This is the hub half: accept + persist them. Minimal — the rich
backup policy (schedule/retention/target selection) is hub-manifest-owned and lands at
slice 10; this slice only mirrors what the agent reports.

### Added
- **`hostBackup` / `hostRestoreTest`** mirror structs in `hostReportPayload`
  (`internal/api/handler.go`) — field-for-field with the agent's `hub.Backup` /
  `hub.RestoreTest` wire contract. Persisted verbatim in `report_json` (no new columns —
  slice-5 precedent).
- **A FAILED restore-test is logged prominently** (`[WARN]`, the loudest DR signal there is);
  a failed backup is logged too. The `host-report` info line now counts backups + restore-tests.
- **`testdata/host-report.golden.json`** updated with a populated `backups[0]` /
  `restore_tests[0]`, kept **byte-identical** with felhom-agent's copy.
- **`TestHostBackup_GoldenContract` / `TestHostRestoreTest_GoldenContract`** — the hub half of
  the bidirectional key-set test (round-trip the golden through the mirror, assert exact keys).

### Notes
- Backward-compatible: an agent that omits/empties these is accepted unchanged. The legacy
  controller report path is untouched (frozen until slice 10).

## v0.7.2 — ingest agent storage_targets (slice 5 Phase A) (2026-06-09)

The agent's slice-5 work populates the host-report's `storage_targets` (previously empty).
This is the hub half: accept + persist them. Minimal by design — the rich, authoritative
storage manifest (desired class/role/policy/creds) is hub-owned and lands at slice 10; this
slice only mirrors what the agent observes.

### Added
- **`hostReportPayload.StorageTargets`** (`internal/api/handler.go`) — a full mirror of the
  agent's `hub.StorageTarget` wire contract (name/type/durable_id/state/reachable/usage/
  content/mount/class_hint/role/`thin_pool`/`smart`). The targets are persisted verbatim in
  the existing `report_json` row (no schema change); the handler counts them and logs a
  `[WARN]` when any are `disconnected` (the storage analog of host-down visibility).
- **`testdata/host-report.golden.json`** — updated to carry two populated `storage_targets`
  (an lvmthin with `thin_pool`, a usb), kept **byte-identical** with felhom-agent's copy.
- **`TestHostStorageTarget_GoldenContract`** — the hub half of the bidirectional key-set test:
  round-trips the golden's `storage_targets[0]` through the mirror struct and asserts the key
  set matches exactly (no missing/extra fields vs the agent). `TestHostReport_GoldenContract`
  also now asserts the targets are persisted + parse back.

### Notes
- Backward-compatible: an older agent that sends `storage_targets: []` (or omits it) is
  accepted unchanged. The legacy controller report path is untouched (frozen until slice 10).

## Repo docs — no hub version change (2026-06-08)

### Changed
- **Reflowed `felhom.eu/CLAUDE.md`** — removed hard mid-paragraph line wraps (prose, list items, blockquotes now single-line); tables untouched; rendered output unchanged.
- **Unified the REPORT/CHANGELOG convention**: this repo's `REPORT.md` switches from *append/cumulative* to **overwrite-latest** (uniform with the sibling repos); `CHANGELOG.md` (this file) stays the cumulative log, newest on top. Updated `REPORT.md`'s header note accordingly (existing sections retained as history). Added an explicit **no-secrets** rule. No hub code change → no version bump.

## v0.7.1 (2026-06-08)

### Changed
- **`/host-report` rejects oversize bodies explicitly with 413** (`handler.go`) instead of silently truncating at the 4 MiB `LimitReader` cap. Reads one byte past `maxHostReportBytes` and returns `413 Payload too large` — a truncated-but-valid JSON could otherwise be accepted as a partial report (silently dropping guests from the mirror). The controller `handleReport` 1 MiB path is **unchanged** (frozen until slice-10 cutover).

### Added
- **Cross-repo contract fixture** `hub/internal/api/testdata/host-report.golden.json` (byte-identical with felhom-agent's copy) + `TestHostReport_GoldenContract` — POSTs the golden through the real `handleHostReport` and asserts 200 + denorm (`guest_total`/`guest_running`/`cloudflared_status`) + both guests upserted, proving `hostReportPayload` still extracts the contract from the real shape. Duplicated contract (no shared types module yet); revisit at slices 5/6.

## v0.7.0 (2026-06-08)

### Added — host-domain ingest (slice 3, additive; controller path untouched)
- **New tables** `hosts`, `guests`, `host_reports` (`store.go migrate()`, idempotent). Full schema now, including columns **inert until slice 10** (`hosts.desired_json`/`desired_generation`/`dr_record_json`, `guests.api_key`/`desired_spec_json`) so the cutover needs no `ALTER`. Nothing reads/writes the inert columns this slice.
- **`POST /api/v1/host-report`** — the agent's heartbeat. Per-host Bearer auth; 4 MiB body; persists the full report + denormalized fields (cpu/mem/disk %, guest counts, cloudflared status); upserts each guest's **reality** columns (`guest_id = "<host_id>/<vmid>"`, hub-derived); returns the control envelope `{status, poll_interval_seconds:900, blocked, desired_generation:0, has_signed_ops:false}` (`blocked` reflects the customer's status; the latter two are reserved/placeholder for slice 4).
- **Per-host key auth** — `checkAuthHost` (Bearer → host → customer), added alongside the unchanged `checkAuthCustomer`. Global key remains a bootstrap fallback.
- **`POST /api/v1/admin/hosts`** — **PROVISIONAL** global-key-only host mint (host_id + per-host api_key); the slice-3 bootstrap until enrollment (slices 7–8) replaces it.
- **Host dead-man's-switch** — `monitor.HostStalenessChecker` over `host_reports`, emitting `host_stale`/`host_down`/`host_recovered` (30m/60m), attributed to the host's customer; registered in `allowedEventTypes`; wired in `cmd/hub/main.go` on the existing 60s ticker. A deliberate **sibling** of the controller `StalenessChecker` (both run until slice 10).
- **Store methods**: `GetHostByAPIKey`, `GetHost`, `ListHosts`, `UpsertHost`, `SaveHostReport`, `UpsertGuestFromReport` (preserves inert columns on conflict), `GetHostStaleness` (skips never-reported hosts), `GuestID`. `Prune` now also prunes `host_reports` (same retention).
- **Tests** (new, hermetic): store, auth (`checkAuthHost`), ingest (valid+envelope+denorm, host_id mismatch→403, unknown-host-under-global→400, blocked→true, oversize→400), admin mint (non-global→403, unknown customer→400, mint+round-trip), host staleness transitions.

### Unchanged (explicit)
- The controller path — `/api/v1/report`, `reports`, `customer_configs`, `checkAuthCustomer`, the existing staleness/deadline checkers — is untouched and still green. The old controller and the new agent report in parallel during slices 3–9; the schema/auth cutover is **slice 10**.

## v0.6.2 (2026-02-26)

### Added
- **Infra backup GFS retention** — New `infra_backup_versions` table stores multiple backups per customer. GFS pruning keeps: all from last 24h, latest per day (7 days), latest per week (4 weeks), latest per month (3 months) — ~14 versions max per customer
- **`GET /api/v1/infra-backup/{id}/versions`** — Returns metadata list of all retained backup versions (date, stack names, disk count) for a customer. Bearer auth.
- **Recovery version selection** — `GET /api/v1/recovery/{id}?version=ID` fetches a specific backup version instead of latest. Response now includes `backup_versions` array with all available versions.
- **Dashboard backup history** — Customer detail page "Infra Backup" card shows version count and collapsible history table (date, apps, disks)

### Changed
- **`SaveInfraBackup()`** — Now INSERTs a new row instead of upserting, preserving history. Automatically prunes old versions via GFS algorithm.
- **One-time migration** — Existing data from `infra_backups` table is copied to `infra_backup_versions` on first startup

## v0.6.1 (2026-02-25)

### Added
- **Delete issues from app detail page** — Known Issues table now has per-row checkboxes with "Delete Selected" and "Delete All Issues" buttons; keeps telemetry data (memory trends, etc.) intact
- **`DELETE /apps/{appName}/delete-issues`** — New POST endpoint supporting `action=selected` (with `issue_ids` form values) and `action=all`

### Fixed
- **Hub-side fingerprint hardening** — `fingerprintIssue()` now strips ANSI escape codes, ISO/syslog timestamps, and lowercases before truncating to 100 chars. Prevents duplicate issue rows when messages differ only by embedded timestamps.

## v0.6.0 (2026-02-25)

### Added
- **Geo-restriction display** (`customer_unified.html`) — New "Geo-korlátozás" section on customer detail pages showing: enabled/disabled status, allowed countries, per-app overrides, last sync time, and sync errors. Only visible when the controller reports geo_restriction data.
- **"Összes geo-korlátozás eltávolítása" button** — One-click removal of all `[felhom-geo]` Cloudflare WAF rules. The Hub calls the Cloudflare API directly (bypasses potentially blocked tunnel), then retries notifying the controller in background (every 30s for up to 10 min) to disable geo in its settings.
- **Cloudflare unblock client** (`internal/cloudflare/unblock.go`) — Minimal Cloudflare API client for deleting geo-restriction WAF rules. Resolves zone ID, finds the `http_request_firewall_custom` ruleset, and deletes rules with `[felhom-geo]` description prefix.
- **`POST /customers/{id}/geo/disable`** route — CSRF-protected endpoint for the geo-disable action.

### Removed
- **Legacy Monitoring UUIDs** — Removed the "Monitoring UUIDs" section from the config form (`config_form.html`), UUID form-field handling from `buildConfigJSON()`, UUID import from `handlePullConfig()`, volatile key entries for `monitoring.ping_uuids.*`, and the commented-out `ping_uuids` section from `controller.yaml.default`. Monitoring is fully handled by the Hub event system since v0.3.0.

## v0.5.0 (2026-02-25)

### Added
- **Configuration page** (`GET /configuration`) — New "Configuration" tab in the web UI with asset management controls. Displays asset file count, manifest generation timestamp, and a "Refresh Assets from Image" button.
- **Manual asset re-seed** (`POST /configuration`, action=`refresh_assets`) — Re-reads the baked-in seed directory, compares SHA-256 checksums with PVC assets, and updates changed files. Rebuilds the manifest afterward. Controllers pick up changes on their next daily sync.
- **`ReSeed()` method** (`internal/assets/assets.go`) — Public method for triggering asset re-seed + manifest rebuild from the web UI.

### Changed
- **Asset seeding: `seedIfEmpty()` → `seedOrUpdate()`** (`internal/assets/assets.go`) — On startup the Hub now compares SHA-256 checksums between the image seed directory and the PVC, updating any changed files instead of only seeding into an empty directory. This means redeploying the Hub image with updated assets automatically propagates them without PVC deletion.
- **`isAssetFile()` expanded** — Now also matches `*-favicon.svg` and `*-favicon.ico` patterns, allowing branding assets like `felhom-favicon.svg` in the manifest.
- **`RebuildManifest()` refactored** — Internal logic extracted to `rebuildManifestLocked()` for reuse by `ReSeed()`.
- **Web Server struct** — Added `assetsMgr` field and `SetAssetManager()` method. Wired in `main.go`.
- **All templates translated to English** — The "Alkalmazások" nav link and telemetry pages (apps.html, app_detail.html, customer_unified.html telemetry section) are now in English, consistent with the rest of the Hub UI.
- **Navigation updated** — All templates now show four tabs: Dashboard, Customers, Apps, Configuration.

## v0.4.1 (2026-02-23)

### Added
- **Per-app telemetry reset** (`store/telemetry.go`, `web/apps.go`) — New "Telemetria törlése" button on the app detail page that deletes all telemetry records and known issues for the selected app. Useful after major app updates when old data is no longer representative. Includes confirmation dialog and flash notification.
- **`DeleteAppTelemetry()`** and **`DeleteAppIssues()`** store methods (`store/telemetry.go`) — Delete all telemetry/issue rows for a specific app_name.
- **`POST /apps/{name}/reset-telemetry`** route (`web/server.go`) — CSRF-protected endpoint that triggers the reset and redirects back with flash message.

## v0.4.0 (2026-02-23)

**App Telemetry & Analytics Dashboard**

### Added
- **`app_telemetry` and `app_log_issues` SQLite tables** (`store/store.go`) — store per-app resource metrics and deduplicated log issues reported by v0.28.0+ controllers.
- **`internal/store/telemetry.go`** — New store methods: `SaveAppTelemetry`, `GetFleetAppSummary` (with P95 memory calculation), `GetAppTelemetryHistory`, `GetAppCustomerBreakdown`, `GetCustomerAppSummary`, `GetAppIssues`, `GetRecentIssuesAllApps`, `PruneAppTelemetry`, `PruneStaleIssues`. New types: `AppTelemetryRecord`, `FleetAppSummary`, `AppTelemetryPoint`, `AppCustomerStats`, `CustomerAppSummary`, `AppIssue`.
- **`/api/v1/report` handler update** (`api/handler.go`) — After saving the standard report, parses the optional `app_telemetry` JSON field and persists it. Backward-compatible: old controllers (no `app_telemetry` key) are unaffected.
- **Fleet app list page** (`GET /apps`) — Hungarian-language dashboard showing all deployed apps fleet-wide with deployment count, avg/P95 memory, catalog estimate/limit accuracy, error/warning badges. Sortable columns, 24h/7d/30d period selector.
- **Per-app detail page** (`GET /apps/{name}`) — Memory trend Chart.js chart (avg + peak, with catalog limit line), per-customer breakdown table, known log issues table (severity, message, occurrence count, affected customers). Includes suggested mem_limit from P95×1.2 rounded to 32M.
- **Customer detail page telemetry section** (`customer_unified.html`) — New "Alkalmazás telemetria" card with per-app memory (current/avg/peak) and log error/warning counts linking to /apps/{name}.
- **Chart.js** (`static/chart.min.js`) — Embedded from controller build, served at `/static/chart.min.js`.
- **"Alkalmazások" nav link** — Added to header navigation across all templates.
- **New CSS** (`style.css`) — `.badge`, `.badge-error`, `.badge-warn`, `.summary-cards`, `.summary-card`, `.chart-container`, `.period-selector`, `.period-btn`, `.accuracy-dot`, `.mem-ok/warn/danger`, `.data-table` styles.
- **Telemetry pruning** (`cmd/hub/main.go`) — `pruneAll()` now also prunes app_telemetry rows older than 90 days and stale log issues not seen in 30 days.

### Changed
- **`internal/web/apps.go`** (new file) — `handleApps`, `handleAppDetail`, `parsePeriod`, `sortFleetSummary`, `aggregateHistoryForChart`, `parseLimitMB`, `memoryColor`, `accuracyClass`, `getCSRFToken` helper functions.
- **`internal/web/server.go`** — Added routes for `/apps`, `/apps/{name}`, `/static/chart.min.js`. Added `memoryColor`, `accuracyClass`, `gt` template functions.
- **`internal/web/embed.go`** — Added `//go:embed static/chart.min.js` directive.

## v0.3.7 (2026-02-21)

**Asset management API**

- New `internal/assets` package: manages app assets (logos, screenshots) on Hub PVC (`/data/assets/`) with automatic seeding from baked-in image copy on first run.
- Two new authenticated API endpoints for controllers to sync assets:
  - `GET /api/v1/assets/manifest` — returns JSON manifest with filenames + SHA-256 checksums
  - `GET /api/v1/assets/file/{filename}` — serves individual asset files
- Dockerfile updated to `COPY assets/ /usr/share/felhom/assets-seed/` for first-run seeding.
- Build script syncs website assets (`*-logo.{svg,png}`, `*-screenshot-*.webp`) into Docker build context.

## v0.3.6 (2026-02-21)

**Human-friendly retrieval passwords**

- Retrieval passwords now use Hungarian word passphrases (e.g. `áldás-plazmid-palánta-süvítve-pócgém`) instead of 64-char hex strings.
- Embedded 29K+ curated Hungarian word list (`hungarian.txt`) via go:embed; 5-word passphrases give ~74 bits of entropy.
- New `configgen.RandomPassphrase(wordCount)` function; all 3 retrieval password generation sites updated.
- API keys remain as hex (machine-to-machine, never typed by humans).

## v0.3.5 (2026-02-21)

**Recovery Endpoint & Customer Standing**

- New `GET /api/v1/recovery/{customer_id}` endpoint: returns both generated controller.yaml and infra backup in a single response for disaster recovery. Auth via `X-Retrieval-Password` header (same as config retrieval).
- Report response now includes `customer_blocked: true` when customer status is "blocked" — allows controllers to detect standing and enter limited mode.

## v0.3.4 (2026-02-20)

- Rename version labels: "Current version" → "Controller version", "Latest version" → "Registry latest".

## v0.3.3 (2026-02-20)

**Bugfixes**

- Fix double "v" prefix in controller version display (showed "vv0.21.1" instead of "v0.21.1").
- Skip deprecated `monitoring.ping_uuids.*` keys in config diff comparison (added to volatile keys).

## v0.3.2 (2026-02-20)

**Hub Version Display**

- Show Hub version in footer of all pages via `hubVersion` template function.
- `web.New()` now accepts `version` parameter (4th arg) — set via ldflags at build time.

## v0.3.1 (2026-02-20)

**Config Diff Display + Pull Config**

- **Value-based config comparison**: Replaced broken SHA256 hash comparison with semantic YAML comparison. Both configs are parsed into maps, flattened to dot-notation keys, and compared by value. Ignores key ordering, whitespace, comments, and volatile fields (`web.session_secret`). Shows actual diff count on customer page ("⚠ Config mismatch — N differences").
- **Config diff endpoint** (`GET /customers/{id}/config-diff`): Fetches live YAML from controller via new `GET /api/config` endpoint, generates Hub YAML via `configgen.Generate()`, returns JSON with per-key diffs (key, hub value, controller value, status). Sensitive values (tokens, passwords, secrets) are masked.
- **Pull Config** (`POST /customers/{id}/pull-config`): Reverse of Push Config — imports controller's current config into the Hub. Extracts identity fields (name, domain, email) and override fields (infrastructure tokens, git credentials, monitoring UUIDs). Preserves existing APIKey and RetrievalPassword.
- **Diff display UI**: "Show Diff" button on customer page expands a table showing all key-value differences with color-coded rows (yellow=changed, blue=hub-only, orange=controller-only).
- **Pull Config button**: Added next to existing "Push Config" with confirmation dialog.

## v0.3.0 (2026-02-20)

**Hub Monitoring Takeover — Event System, Dead Man's Switch, Notifications**

Replaces external Healthchecks.io with a Hub-native event system. The Hub becomes the single source of truth for all customer monitoring, event tracking, dead man's switch alerting, and notification delivery.

### Phase 1 — Event System
- **`events` table** in SQLite: stores all events with customer_id, event_type, severity, message, details_json, source, timestamp
- **Indexes**: `idx_events_customer_created` (customer + time DESC), `idx_events_type` (type + time DESC)
- **Store methods**: `SaveEvent`, `GetRecentEvents`, `GetEventsByType`, `GetLatestEventByType`, `GetAllRecentEvents`, `CountEventsBySeverity`, `PruneEvents`, `GetActiveCustomerIDs`
- **`POST /api/v1/event`** endpoint: accepts structured events from controllers, validates event_type against 27 allowed types, validates severity (info/warning/error), stores in DB
- **Enhanced auth**: `checkAuthCustomer()` validates per-customer API keys match the customer_id in payload; global key bypasses ownership check
- **Prune**: events pruned alongside reports at 04:30 Budapest time

### Phase 2 — Dead Man's Switch
- **Staleness checker** (`internal/monitor/staleness.go`): runs every 60s, detects when controllers stop reporting
  - ok→stale (>30min): inserts `node_stale` warning event
  - any→down (>60min): inserts `node_down` error event
  - stale/down→ok: inserts `node_recovered` info event
  - Skips blocked customers, no false alerts on startup
- **Backup deadline checker** (`internal/monitor/deadline.go`): runs daily at 05:00 Budapest
  - Detects missing `backup_completed` events since midnight → inserts `expected_backup_missed` error
  - Detects missing `db_dump_completed` events → inserts `expected_dbdump_missed` error
  - Grace: skips customers with `node_down` state
- **`scheduleDaily()`** helper: goroutine that sleeps until target time (Europe/Budapest), runs function, loops
- **`/healthz`** enhanced: returns 503 if SQLite Ping fails

### Phase 3 — Notification System
- **Dispatcher** (`internal/notify/dispatcher.go`): processes events and sends emails via Resend API
  - **Operator channel**: English emails to operator for warning/error events, 1h cooldown per customer:eventType
  - **Customer channel**: Hungarian emails per event_type, respects customer preferences (enabled_events, cooldown_hours), blocked customers skipped
  - **Test bypass**: `test` event type skips cooldown/preferences, sends directly to customer email
- **Email templates** (`internal/notify/templates.go`): operator (concise English), customer (Hungarian per event type with complete message table)
- **Cooldown tracking**: in-memory maps with per-customer:eventType granularity
- **`customer_notifications` table**: added `cooldown_hours` column (default 6)
- **`notification_log` table**: added `channel` column (operator/customer)
- Wired into `/api/v1/event` handler and staleness/deadline checkers

### Phase 4 — Hub UI
- **Events section** on customer detail page: last 50 events, severity filter buttons (All/Errors/Warnings/Info), colored severity badges
- **Dashboard badges**: error+warning count in last 24h per customer, clickable to customer events
- **Notification log**: shows channel column (operator/customer) in customer detail page
- **Config form**: Monitoring UUIDs section marked as "Legacy" with deprecation notice, collapsed by default

### Phase 6 — Config Cleanup
- **`controller.yaml.default`**: `monitoring.ping_uuids` section commented out (deprecated)
- **`buildConfigJSON`**: only writes `ping_uuids` to config JSON if user explicitly provides UUID values (new configs get none)

---

## v0.2.2 (2026-02-20)

**Config Hash Comparison**

- **Config sync status** on unified customer page: compares SHA256 hash of controller's
  `controller.yaml` (from report payload) against Hub-generated YAML. Shows "In sync",
  "Config mismatch", or "Unknown" (controller needs v0.20.0+ to report hash).
- Visible in the Controller Update section next to Push Config button.

---

## v0.2.1 (2026-02-20)

**Unified Customer Management**

All customer views consolidated into a single page. New management features: blocked status,
dashboard merge, config push, and auto-config creation.

### New features

- **Unified customer page — `/customers/{id}`:**
  - Single page showing both configuration info and live report data
  - Replaces separate `/configs/{id}` (config detail) and `/customers/{id}` (report detail) pages
  - Shows config management (credentials, setup commands, YAML preview) when config exists
  - Shows "Create Config" button for manual (report-only) customers
  - Old `/configs/{id}` URLs redirect to `/customers/{id}`

- **Dashboard shows pending customers:**
  - Customers with config but no reports appear on dashboard with "PENDING" status
  - All metric columns show "—" for pending customers

- **Blocked/Banned status:**
  - Customers can be blocked via button on detail page
  - Blocked customers hidden from Dashboard
  - Reports still accepted (prevents controller retry loops) but notifications suppressed
  - "BLOCKED" badge shown on Customers list and detail page
  - One-click unblock button

- **Config push to controller:**
  - "Push Config" button on unified page (visible when controller URL known)
  - Generates YAML and POSTs to `{controller_url}/api/config/apply`
  - Note: requires controller v0.20.0+ with config apply endpoint

- **Auto-create config from report data:**
  - "Create Config" button on manual customer pages
  - Pre-fills customer name from report, generates credentials
  - Redirects to edit form for additional fields

### Changes

- Customers list: all rows now link to `/customers/{id}` (unified page)
- Config badges: new MANAGED/MANUAL/BLOCKED pill-style badges
- `customer_configs` table: added `status` column (active/blocked)
- Status functions handle "pending" and "blocked" status values

---

## v0.2.0 (2026-02-20)

**Customer Configuration Management**

New "Configurations" section for pre-provisioning customer nodes. Operators can configure
customer settings in the Hub web UI, then `docker-setup.sh` downloads a ready-made
`controller.yaml` — reducing deployment to a customer ID and password.

### New features

- **Web UI — `/configs` pages:**
  - List all customer configurations in a table
  - Create new configuration: customer identity, infrastructure secrets (CF tunnel/API tokens),
    git sync credentials, monitoring UUIDs — organized in collapsible sections
  - Detail page: shows credentials (retrieval password, per-customer API key) with copy-to-clipboard,
    setup commands (`docker-setup.sh` and `curl`), live YAML preview
  - Edit and delete configurations
  - Navigation tabs (Dashboard / Configurations) on all pages

- **Config retrieval API — `GET /api/v1/config/{customer_id}`:**
  - Authenticated via `X-Retrieval-Password` header (separate from Bearer token)
  - Generates complete `controller.yaml` by deep-merging template with customer overrides
  - Template sourced from `controller.yaml.example` (fetched from Gitea repo periodically)
  - Falls back to embedded default template if fetcher not configured

- **Per-customer API keys:**
  - Each customer config gets its own API key (auto-generated, 64 hex chars)
  - Controllers can authenticate with per-customer key instead of the shared global key
  - Backward compatible — global `report_api_key` continues to work alongside per-customer keys

- **YAML generation (`internal/configgen` package):**
  - Deep-merge of template + customer-specific overrides
  - Programmatic injection: customer identity, hub config, session secret
  - Shared by both API handler and web UI preview

- **Template fetcher (background goroutine):**
  - Periodically fetches `controller.yaml.example` from Gitea (configurable interval)
  - Requires `registry.username` + `registry.token` in hub.yaml
  - Falls back to `go:embed` default template when not configured

- **Data layer:**
  - New `customer_configs` SQLite table
  - 6 CRUD methods: Save, Get, List, Delete, GetByAPIKey, UpdateRetrievalPassword

### Configuration

New `registry` section in `hub.yaml`:

```yaml
registry:
  image: "gitea.dooplex.hu/admin/felhom-controller"
  username: ""               # Gitea credentials (for version checker + template fetcher)
  token: ""
  check_interval: "6h"
  template_interval: "1h"   # How often to refresh controller.yaml.example
```
