# REPORT — controller v0.70.0: config-apply self-restart + geo-restriction UX fixes (2026-06-16)

**Deployed:** controller **v0.70.0** on guest 9201 / felhom-pve (bootstrap-managed; healthy, hub-reporting OK).
**Scope:** controller-only. Fixes found during live geo testing (rotating the Cloudflare API token).
**Commits (trunk, per-commit green gate):** A `ba87412`, B `02a4ba0`, C `09d75c1`, docs `c514c00`, live-fix `9b7a265`.

## What shipped

1. **Config-apply self-restart (core fix).** `POST /api/config/apply` previously wrote the new
   `controller.yaml` but logged "restart needed" and left stale in-process singletons — the Cloudflare
   client is built once at startup, so a rotated CF token kept 403'ing until a manual LXC restart. Now:
   byte-identical re-push → no-op (no write, no restart); changed config → write, respond 200 (flushed),
   then **graceful self-restart** (`os.Exit(0)` after ~500 ms; container is `restart: unless-stopped`).
   Exit is behind an injectable `Restarter` seam. Removed the stale wording and the dead `OnConfigApplied`
   hook (Phase-1-retired infra-backup push).
2. **Manual "Vezérlő újraindítása" button** → `POST /api/selfrestart` (auth + CSRF via `/api/` mount),
   same helper; confirm → POST → poll `GET /` every 2 s → reload.
3. **Immediate hub report push on geo change** (`Router.reportPushNow`, wired in `main.go`): a successful
   geo save and a successful manual geo sync fire a non-blocking report push so the hub reflects the new
   state within seconds instead of after the ~15-min cycle. Scoped to geo handlers.
4. **Always report `geo_restriction`** (`buildGeoRestrictionReport`): always populated (Enabled=false,
   empty countries when never configured) so the hub always renders the section ("Inaktív" when off).
5. **Country autocomplete fixed.** See root cause below.

## Country autocomplete — root cause (diagnosed live, NOT the hypothesised JS throw)

`filterCountries` runs without error and **correctly populates** the list, but reveals it with
`list.style.display = ''`. The `.geo-country-list` CSS default is `display:none` (style.css:3084), so
clearing the *inline* style falls back to the stylesheet and the populated list stays hidden — **no
console error, just an invisible dropdown**. Proven live via `javascript_tool`: calling
`filterCountries('Német')` set `innerHTML` to the "Németország (DE)" option but computed `display`
stayed `none`; forcing `display:block` revealed it. Latent since the geo feature's first commit
(`e1fb852`), not a recent regression; the operator's "1 console error" was unrelated (the stray
DevTools filter noted in the task). **Fix:** reveal with `'block'`.

## Tests (non-hollow, per-commit green gate; companions proven red pre-fix)

- A: `selfrestart_test.go` — changed config → restart once; **identical → not called (companion, red
  without the no-op guard)**; invalid YAML → not called; `/api/selfrestart` → restart once.
- B: `geo_test.go` — geo save success → push once; **invalid country → no push (companion)**.
  `geo_report_test.go` — `buildGeoRestrictionReport(nil)` → non-nil disabled (**companion vs old
  nil-omit**); passthrough; disabled-nil-countries.
- C: template/CSS visibility fix — verified live (no Go unit test applies).

## Live verification on guest 9201 (all 5 pass)

- **(a) config-apply auto-restart:** no-op re-push → `"…változatlan…"`, container `StartedAt` unchanged;
  changed config → `"…a vezérlő újraindul."` + `StartedAt` advanced (11:04:18 → 11:08:50) + healthy — **no
  manual step**.
- **(b) restart button:** renders (`btn-restart-controller` in rendered HTML); `POST /api/selfrestart`
  → `"Újraindítás folyamatban…"` + restart (11:14:19 → 11:14:50) + healthy. (Full button click not
  automated — its `confirm()` dialog blocks the browser extension; the poll-reload JS is code-reviewed.)
- **(c) geo save → hub within seconds:** save → controller logs "Hub report pushed successfully" 1 s
  later; hub's latest demo report `received_at = 11:15:52` (the save time) with
  `geo_restriction = {"enabled":true,"allowed_countries":["HU"]}`.
- **(d) hub "Inaktív" when off:** geo disabled → report carries `geo_restriction = {"enabled":false,…}`
  (present-but-disabled = the data the hub renders as "Inaktív"; pre-fix this field was omitted and the
  section hidden). Demo re-enabled (HU) afterwards.
- **(e) country dropdown:** typing "Német" lists **Németország (DE)** on the deployed 0.70.0 (the
  `'block'` fix; confirmed the deployed JS uses `'block'` and the list becomes visible).

## Bug found + fixed during verification

The restart button was initially placed inside the `{{if .RetrievalPassword}}` block, so it was hidden
on the demo (no retrieval password set). Moved outside the conditional (commit `9b7a265`), rebuilt +
redeployed 0.70.0, re-verified it renders.

## Notes / cleanup

- All temp files removed from the build host (incl. a copied `controller.yaml` that held plaintext
  secrets), guest, and local; the demo's `controller.yaml` was restored to its clean pre-test content.
- Out of scope (untouched): the Komga healthcheck; extending the immediate-report-push pattern beyond
  geo handlers.
