# REPORT — v0.315.0: one app page with four tabs (2026-10-15)

## 1. Baselines

| Repo | `main` at start | Version | → |
|---|---|---|---|
| felhom-controller | `85f65c7` | v0.314.0 | **v0.315.0** |
| felhom.eu | `06e7cf8c` (the task said `3263bb2`; it had moved — two other sessions are pushing) | docs only | — |
| app-catalog-felhom.eu | `e67aad4` | read only | — |

Architecture read before any claim: `02-controller-module-map.md` (`web/`, the R-571 alert-placement
rule), `10-localisation.md` §7, `15-media-library.md` (the Plex claim path), and the controller's
`CLAUDE.md`, `REUSE.md` and `.claude/rules/{ui-hungarian,gates,unprompted-work}.md`.

**Where the work ran.** Edited on the Windows workstation; **built and tested on DooPlex** in an
isolated scratch clone (`/mnt/5_hdd/felhom.eu/scratch/cc-apptabs`) so the shared DooPlex checkout —
which two other sessions are using tonight — was never dirtied. The sync normalises line endings to
LF and restores any file it did not mean to touch, because this checkout has `core.autocrlf=true`
while six files (`.gitignore`, `Dockerfile`, `Makefile`, the three infra templates) are stored in git
WITH CRLF; a blanket normalisation rewrote all six on the first attempt.

## 2. Files created / modified

**Created (11)**
`controller/internal/web/app_page.go` · `after_start.go` · `app_page_test.go` · `guide_render_test.go` ·
`controller/internal/stacks/guide_test.go` ·
`templates/app_shell.html` · `app_settings.html` · `app_data.html` · `app_guide.html` · `app_logs.html` · `app_fields.html`

**Deleted (4 templates)** `templates/app_info.html` · `logs.html` · `app_export.html` · `tier2_config.html`
— with the three page handlers that rendered them (`logsHandler`, `exportPageHandler`,
`tier2ConfigPageHandler`). The POST handlers beside them (`tier2ConfigSaveHandler`,
`appEmailToggleHandler`) stay, with their URLs.

**Modified (main ones)** `web/server.go` (routes + the GET-only redirects) · `web/handlers.go`
(`appDetailHandler` → `appCommonData`; `deployHandler` → `deployPageData` + a thin renderer) ·
`web/media_events.go` (`applyPlexClaim` extracted) · `web/tier2_config_handler.go` (redirect targets) ·
`templates/deploy.html` (install-only; 1197 → 544 lines) · `stacks.html`, `dashboard.html`,
`backups_apps.html`, `app_import.html` (links) · `stacks/metadata.go`, `metadata_i18n.go`,
`appinfo_address.go`, `manager.go` (the guide) · both locale files · `scripts/template_id_gate.py`,
`scripts/test_gate_decoys.py`, `scripts/i18n_go_keys.json`.

## 3. Commits on `main`

| Commit | What |
|---|---|
| `e66d466` | v0.315.0 — the slice: tabs, routes, the after-start registry, the guide, the Pi removal, the fixtures. One commit, because the template split, the routes and the fixtures cannot be green apart |
| `fe0228c` | style the tab bar; reuse the hero classes that already have rules (**found in a browser**) |
| `db52f5a` | close the log tab's `<script>`; `TestAppPage_ScriptTagsAreBalanced` (**found in a browser**) |

Baseline `85f65c7` -> `db52f5a`. felhom.eu `06e7cf8c` -> `5d4538cc` (docs).

## 4. Tests and red-proofs

**New test groups (9 functions across 3 files), all through the production router where routing is
the subject.**

| Test | Asserts |
|---|---|
| `TestAppPage_DeployedDefaultsToSettings` | `/apps/{slug}` renders the settings tab (`data-tab="settings"` + `aria-selected="true"`), all four tabs present, Mukodes offers restart+stop and not start, **the header contains no `stackAction(`**, no Pi/x86 text |
| `TestAppPage_NotDeployedShowsGuideOnly` | no tab bar, `data-install-cta`, every tab suffix → 302 `/apps/grocy`; unknown app 404; unknown suffix 404 |
| `TestAppPage_OldURLsRedirectGETOnly` | the five old GETs → 302 with the right Location, query carried, `?raw=1` still text/plain, unknown name 404, **POST to `/backup` and `/app-email` reaches its handler** |
| `TestAfterStart_PlexThroughRouter` | POST `/apps/plex/after-start/PLEX_CLAIM` → the real registry → a fake Plex, by ADDRESS; the gate moves; the card disappears |
| `TestAfterStart_NoActionNoCard` | an unregistered field: no card, POST 404, **zero calls to the fake** |
| `TestAfterStart_RegistryAloneIsNotAnInvitation` | a REGISTERED action whose field the catalog does not declare: 404, zero calls, the gate untouched |
| `TestAfterStart_CardHiddenWhenNotNeeded` | registered + `Needed()==false` → no card |
| `TestAfterStart_PlexClaimOldRouteStillWorks` | `/apps/plex/plex-claim` runs the same entry |
| `TestInstallPage_BackGoesToApp` | Vissza and Mégsem href `= /apps/grocy`; the post-install links point at the tabs; unknown app 404 |
| `TestAppPage_EachTabRendersItsOwnContent` | one marker per tab, and **the log poller on the log tab only** |
| `TestGuide_RenderRules` | checked renders / empty does not / absent says so / `<script>` escaped / DOMAIN filled |
| `TestGuide_EnglishFallsBackFieldByField` | English FAQ + Hungarian sections; a blank English intro falls back; `checked_version` survives; the Hungarian page is unchanged |
| `TestGuide_*` (stacks, 8 funcs) | parse, the render gate, the overlay field by field, extras dropped+counted, `WithAddress` over every string, `Clone` not shared, and the catalog snapshot carries no guide yet |

**Red-proofs — each break seen failing, then reverted.**

| # | Break | Result |
|---|---|---|
| A | default tab → guide for a deployed app | `TestAppPage_DeployedDefaultsToSettings` FAILS |
| B | drop the not-deployed tab redirect | `TestAppPage_NotDeployedShowsGuideOnly` FAILS |
| C | drop `&& r.Method == http.MethodGet` from the `/backup` redirect | `TestAppPage_OldURLsRedirectGETOnly` FAILS |
| C2 | 302 → 301 | `TestAppPage_OldURLsRedirectGETOnly` FAILS |
| D | remove the `/after-start/` route from `server.go` | `TestAfterStart_PlexThroughRouter` FAILS (404) |
| E1 | drop the no-registered-action guard in `afterStartFields` | `TestAfterStart_NoActionNoCard` FAILS |
| **E2** | drop `!declared` in `appAfterStartHandler` | **PASSED at first — see below** |
| E2′ | the same break, after writing `TestAfterStart_RegistryAloneIsNotAnInvitation` | FAILS: *"POST for a field the catalog does not declare = 200"*, **2 calls reached Plex**, the gate moved |
| F | guide gate `Rendered` → `Sections` | `TestGuide_RenderRules` FAILS |
| G | install Vissza → `/stacks` | `TestInstallPage_BackGoesToApp` FAILS |
| H | `deepCopyStack` stops cloning the guide | `TestDeepCopyStackMetaSharesNoReference` FAILS, naming `Guide.Sections` and `Guide.FAQ` |
| I | remove `</script>` from `app_logs.html` again | `TestAppPage_ScriptTagsAreBalanced` FAILS: "logs: 3 `<script>` opened, 2 closed" |
| 1–3 | `Rendered()` without `checked_version`; `overlayGuide` replacing the FAQ whole; `WithAddress` skipping the guide | the three matching `TestGuide_*` FAIL |

**E2 is the finding of this session.** The handler has two guards that look like one: the field must
be registered in Go AND declared by this box's catalog. Deleting the second left the whole suite
green, because every test that reached it was already refused by the first. With it deleted, a POST
naming a field the catalog does not declare **reached Plex and opened the setup gate**. The missing
test was written, the break repeated, and it now convicts. This is the project's own
„a comment asserting an invariant needs a test pinning it" class, found the way the rule says to find
it.

**Also caught by a red-proof discipline, not by the suite:** my first full-gate run read
`go test ./... | grep -v ok | head -25`, whose exit code is `head`'s. It reported 0 while
`TestDeepCopyStackMetaSharesNoReference` was failing (break H, caused by the new guide slices). Re-run
capturing `go test`'s own `$?`: **`GO_TEST_RC=0`, 37 packages `ok`, zero `FAIL` lines.** The
„exit codes that lie" trap, hit and corrected in-session.

**TWO DEFECTS THE SUITE COULD NOT SEE, both found in a browser.** This is the case for Claude in
Chrome running on the workstation, and it is worth stating plainly: every endpoint-level marker
passed on both.

1. **The tab bar had no CSS and the logo was unsized.** The shell was written with new class names -
   `app-hero`, `app-hero-logo`, `app-tabs` - and the first two duplicate names the design system
   already has rules for (`app-info-hero`, `app-info-logo`), while the third had none at all. The
   page answered 200, carried every `data-*` marker, and showed four bare underlined links and a
   logo filling a third of the screen. Fixed in `fe0228c`: the shell reuses the existing hero
   classes, and the tab bar is styled to design system v2 - measured live in the browser as
   `display: flex`, `border-bottom 1px rgb(34,52,79)` (`--line`), active `rgb(46,168,245)`
   (`--blue-bright`) on `rgb(15,27,46)` (`--bg-1`), radius 2px.
2. **The log tab's `<script>` was never closed, so the live poller was dead.** The body was lifted
   out of `logs.html` by line range and the range stopped one line short. `html/template` parsed it,
   the page rendered, and `TestAppPage_EachTabRendersItsOwnContent` found
   `setInterval(window.fetchLogs` exactly where it expected it - **because the text was there.**
   Chrome refused the block with "SyntaxError: Unexpected token '<'" and the log never refreshed.
   Fixed in `db52f5a`, with `TestAppPage_ScriptTagsAreBalanced` red-proved.

   **The lesson, in the project's own terms:** a marker proves a string is present; it does not
   prove the browser will execute it. The positive observable is
   `typeof window.fetchLogs === "function"`, which is what the live check now reads.

## 5. Test count

`internal/web` + `internal/stacks` test functions: **+22** (13 new functions). Parity CASES: 145 -> 148.

## 6. Deployed versions

| Box | Before | Now |
|---|---|---|
| demo-hp guest 9201 | 0.314.0 | **0.315.0**, `Up ... (healthy)` |
| Tester 1, demo-felhom | 0.314.0 | unchanged - not touched |

Image `gitea.dooplex.hu/admin/felhom-controller:0.315.0`, built three times from a clean tree
(`git status --porcelain` empty and HEAD == origin/main each time) as the two browser findings were
fixed. **The floor is NOT raised**: per `.claude/rules/unprompted-work.md` item 6 that waits until it
has run on Tester 1, demo-hp and demo-felhom through the normal update path with a green box walk on
all three. demo-hp is one of the three, not the gate.

**For anyone rebuilding the same version:** the stylesheet's cache key is `?v={{.Version}}` with
`max-age=3600`, so a second build of 0.315.0 serves new CSS under a key the browser already holds. It
cost twenty minutes here. It cannot reach a household - a released version is built once - so it is
recorded, not filed.

## 7. NOT yet live-validated

1. **The operator's own look at the page in a browser** — one installed and one not-installed app on
   demo-hp. Asked for in `STATUS.md`. Claude in Chrome runs on the Windows workstation and was used
   for exactly this (§9); the operator's judgement of the LAYOUT is still theirs to give.
2. **A real Plex claim through the new card.** The old path is proven live (R-1060, 2026-10-15); the
   new card reaches the same `applyPlexClaim` and is proven against a fake Plex that answers as the
   measured one does. No real claim was made — it needs the household's code and a throwaway server.
3. **A catalog guide rendered from a real template.** No template carries `app_info.guide` yet; the
   render is proven against fixtures and a unit test.

## 8. Evidence

`/mnt/5_hdd/felhom.eu/evidence/app-page-2026-10-15/` on DooPlex, copied off the boxes at the end of
each phase and before the scratch clone was deleted: `gates/` (the runner all green, 53 decoys,
`go test ./...` with its own exit code), `live/` (every page fetched in the endpoint walk, cookie
jars stripped) and `browser/` (four screenshots for the operator).

## 9. Live validation - demo-hp guest 9201, 0.315.0

The OMV work another session is running tonight is on demo-hp's guests **9310/9311**; 9201 was free.
N100 was left alone (the media-stack session has it).

**Endpoint-level, authenticated, through the endpoints the UI invokes.** Every assertion is on an
ASCII `data-*` marker with a positive and a negative control - an accented Hungarian pattern through
`ssh -> pct exec -> bash` returns a false `0` that reads exactly like the markup being gone.

| Checked | Result |
|---|---|
| all five tab URLs on an installed app | 200 each |
| content per tab | run card / data tab / guide / poller each on exactly one tab; the bar on all four |
| the selected tab per URL | `/apps/x`->settings, `/settings`->settings, `/data`->data, `/guide`->guide, `/logs`->logs; `aria-current="page"` once |
| the header | **0** `stackAction(` before the hero; the Mukodes card offers restart+stop for a running app |
| a not-installed app | no tab bar, no run card, one Telepites; all four tab suffixes **302 -> `/apps/grocy`** |
| the five old URLs | 302 each, to `/logs`, `/data`, `/data`, `/settings`, `/install`; **0 of them 301**; `?raw=1` carried through; the tab answers `text/plain` |
| POST `/stacks/adventurelog/backup` | **303 -> `/apps/adventurelog/data?flash=flash.tier2.saved`** - the save ran and came back to the tab holding the form |
| after-start POSTs (with a CSRF token) | unknown field 404, unknown app 404, **a registered env var on the wrong app 404**; without a token 403, which is what proves the 404s are the handler's |
| Pi / x86 badges | 0 across every page fetched; `meta-badge` (22) and `Alkalmaz` (42) as positive controls |
| the guide | `data-guide-missing` on the guide tab, no rendered guide - no catalog template carries one yet |
| the install wizard | Vissza and Megsem both `href="/apps/grocy"` |
| negative controls | unknown app, unknown tab suffix and unknown stack name all 404 |

**Plex's card is absent, and the reason was read rather than assumed:** its template declares
`after_start` and `PLEX_CLAIM`, and its gate is `state: open` since 2026-10-15T08:45:53Z - the
operator's real claim (R-1060). `Needed()` is therefore false, which is the
`TestAfterStart_CardHiddenWhenNotNeeded` branch. A positive control would mean un-claiming the
operator's real Plex server; not done.

**The data tab's Tier-2 section, with both controls:** `adventurelog` and `bookstack` keep their data
on the system disk and get the honest `data-system-backup="same_disk"` sentence and no target picker
(the `app_data_not_hdd_same_disk` branch); `paperless-ngx`, `plex` and `calibre-web` are HDD apps and
each gets the real save form. A missing form on one app was a branch, not a defect - checked before
it was reported.

**In a real browser** (Claude in Chrome; four screenshots in `evidence/.../browser/`): the settings,
data and logs tabs and the not-installed view all render correctly; the tab bar's computed style
matches the design tokens; `window.fetchLogs` is a function on the log tab and refreshing the log
works; **the console is clean on a fresh load**. "Elso lepesek" on Grocy's page shows the household's
own address (`kamra.enkisfelhom.hu`), so R-498 travels through the new page.

## 9b. Teardown - three layers, stated

- **Machine:** nothing provisioned. The probe scripts, the fetched pages and the password file are
  removed from guest 9201 and from demo-hp (0 leftovers, verified). The password went file->file, was
  never printed, and no copy reached Windows or git.
- **Host:** the DooPlex scratch clone (`scratch/cc-apptabs`) and the `felhom.eu` sibling symlink the
  shared gates need are deleted; the shared checkout two other sessions are using was never dirtied.
  Evidence was copied off first.
- **Hub:** nothing created. No customer, no floor change.

## 10. Parity fixtures (the §9 exception), by name

**Removed (33).** `app_info_*` ×21 · `app_export` · `logs` · `deploy_deployed_{running,stopped,restored_login}` ·
`tier2_{not_hdd,not_hdd_protected,not_hdd_same_disk,not_hdd_absent,notarget_disabled,target_ssd,target_auto}`.

**Added (36).** `app_settings_*` ×21 (`not_checked`, `deployed`, `operator_creds`, `updating`,
`setup_gate_{button,probe,native}`, `after_start`, `install_hold`, `close_signup`,
`close_signup_native`, `signup_native`, `signup_native_open_failed`, `signup_closed`, `signup_window`,
`lost_files`, `known_login_changed`, `ladder_steps`, `hold_log`, `running`, `stopped`,
`restored_login`) · `app_data_*` ×9 (`export`, `deployed`, and the seven Tier-2 scenarios) ·
`app_guide_*` ×4 (`installable`, `available`, `full`, `no_guide`) · `app_logs`.

**Every removed case's scenario is carried by a new one** — the names map one to one except that
`app_info_deployed` split (its data-folder half is `app_data_deployed`) and two cases were added for
content no old case had: `app_guide_full` (a rendered guide with sections and FAQ) and
`app_guide_no_guide` (the „no guide yet" line).

**Changed, and NOT covered by the task's exception list (14).** The task's §9(b) names the pages it
expected to change. These fourteen also changed, and each is required by the task's own §2.6 and
Part 3 — a link change and a badge removal ARE byte changes:

- `deploy_new`, `deploy_new_blocked`, `deploy_new_memory_blocked` — the Pi badge removed (Part 3), the
  Vissza/Mégsem retargeted (§2.5). *(In §9(b)'s `deploy_*` set.)*
- `stacks_full`, `stacks_unhealthy_stop`, `stacks_install_interrupted` — the Pi badge removed, the
  install and log links retargeted. *(In §9(b)'s `stacks_*` set.)*
- `dashboard_full`, `backups_apps_{ok,error,running,other,stale_copy,offsite_offer,interrupted_run}` —
  **not in §9(b)'s list**, but §2.6 requires exactly these links to be updated. Stated here rather
  than quietly regenerated.

**Byte-identical, and that is the proof of no collateral change:** every other fixture, 98 of them,
including `catchall_app` and `app_import_{empty,bundles}`. The app-import page needed a comment about
why one link deliberately keeps the old URL; a `//` JS comment changed its bytes, so it is written as
`{{- /* … */}}` with the trim marker and the page is unchanged.

## 11. Observations

- **NOT-A-FINDING:** `page.title.tier2_config` became dead the moment `tier2ConfigPageHandler` was
  deleted (it was the only producer). Removed from both locale files, from
  `scripts/i18n_go_keys.json` and from `i18n_wiring_test.go`'s two lists in the same commit. Caused by
  this change, so cleaning it is part of it, not scope creep.
- **NOT-A-FINDING (fixed without a row, the size rule):** `scripts/template_id_gate.py` was
  file-scoped, so the shared `app_deploy_fields` partial made it convict ids that are demonstrably on
  the page. It now follows `{{template}}` includes transitively. The hazard that buys is a VACUOUS
  check, so it ships with a scope decoy — a reference planted in `deploy.html` to an id defined only
  in `app_data.html`, a file `deploy.html` does not include — which the gate must still convict. It
  does. 53 decoys green.
- **NOT-A-FINDING:** the i18n gate caught „Please" in the new English string (the copy style forbids
  pleading); reworded before the commit.
- **FILED: R-1067** — the catalog still carries `pi_compatible:` and nothing reads it. Deliberately
  left: a box on 0.314.0 would show „csak x86" on every app. Gated on the fleet floor reaching
  0.315.0. (A row and not a session fix: it is another repo and it is blocked on the floor.)
- **FILED + CLOSED: R-1066** — no architecture document covered the app page. Closed by this task's
  `02-controller-module-map.md` „The app page" and `10-localisation.md` §7 additions.
- **Capability map:** no row covers „the app page", so none moved. Said rather than assumed.
- **Register size: 156 before → 157 after; 1 opened (R-1067), 1 opened-and-closed (R-1066).**
- **System poster:** no fact in `felhom-system-poster.facts.md` changed (no machine, role, traffic
  path, backup tier, time, retention, key or known gap). Neither file edited; nothing added to STATUS.
- **Behaviour change worth naming:** the initial-credentials and default-login cards used to render
  only when `HasAppInfo` was true — incidental (the FileBrowser branch set `HasAppInfo = true` by hand
  just to make its credentials show). On the settings tab they are no longer gated on catalog copy
  existing. A login is not catalog prose.
