# REPORT — Launcher polish: monogram reveal-on-failure + placeholder on every icon surface (v0.163.1)

**Date:** 2026-07-24 · **Repo:** felhom-controller · **Target:** v0.163.1 · No agent coupling; MinAgent unchanged.

## 1. Baseline used

- felhom-controller `main` @ `7a53cb4`, version `v0.163.0` — **matched exactly** (clean tree,
  HEAD == origin/main, CHANGELOG top = v0.163.0). No drift.

## 2. Files modified

**Templates / CSS**
- `controller/internal/web/templates/launcher.html` — both tile branches' `onerror` final step now
  adds `this.parentElement.classList.add('launch-tile--noimg')`.
- `controller/internal/web/templates/style.css` — `.launch-mono { display: none; inset:0; … }` +
  `.launch-tile--noimg .launch-mono { display: flex; }` (monogram = failure-only).
- `controller/internal/web/templates/backups_apps.html` — the allowlisted aligned row's icon now
  uses the canonical `data-fallback="/static/app-placeholder.svg"` + 3-step chain; header comment updated.
- `controller/internal/web/templates/stacks.html` — `data-fallback` always present:
  `{{if $im}}/static/infra-logo.svg{{else}}/static/app-placeholder.svg{{end}}`.
- `controller/internal/web/templates/app_info.html` — hero logo aligned to the 3-step chain +
  placeholder; **screenshots untouched** (still `onerror="this.style.display='none'"`).
- `controller/internal/web/templates/deploy.html` — deploy logo aligned; kept its `.LogoURL`/`.LogoPNGURL` data source.

**Tests**
- `controller/internal/web/launcher_polish_test.go` — NEW (5 test functions).

**Docs**: `CHANGELOG.md` (v0.163.1), `CONTEXT.md` (rule recorded), `REPORT.md` (this file).

**Gate script:** `app_row_dedup_gate.py` does NOT pin the `onerror` chain (only `app-row-icon`
presence + forbidden structures), so no gate-script edit was needed; all three gates stay green.

## 3. Commits pushed to `main`

- `2c80868` — templates + CSS + tests + CHANGELOG + CONTEXT.
- `<REPORT commit>` — this REPORT.md.

## 4. Tests + red-proofs

Five new tests, all green. **2 red-proofs applied → observed FAIL → restored → re-green:**

| # | Group | Mutation | Test | Observed FAIL |
|---|-------|----------|------|---------------|
| A | launcher | removed `classList.add('launch-tile--noimg')` from both `onerror` else branches | `TestLauncher_MonogramRevealOnFailure` | reveal-hook count 0 (want 2) — the monogram would never re-appear for a logo-less tile |
| B | placeholder | reverted `backups_apps.html` to the old 2-step `onerror` chain | `TestBackupsApps_IconPlaceholder` | canonical 3-step chain absent → logo-less row dead-ends hidden |

**New test functions (5):** `TestLauncher_MonogramRevealOnFailure` (Group A),
`TestBackupsApps_IconPlaceholder`, `TestStacks_IconPlaceholderAndInfra`,
`TestAppInfo_HeroPlaceholder_ScreenshotsUntouched`, `TestDeploy_LogoPlaceholder` (Group B).

Two test-only fixes made while writing them (not code bugs): the reveal class legitimately appears
inside the `onerror` JS string, so Group A asserts its count == 2 (both are `classList.add` hooks,
none in a `class=` attribute); and `{{.LogoPNGURL}}` is JS-escaped (`\/…`) inside `onerror`, so the
deploy test asserts the slash-free filename `docmost-logo.png`.

## 5. Test count & suite

- `go build ./... && go vet ./... && go test ./...` — **all green, 0 FAIL/panic.**
- Gates green: `app_row_dedup_gate.py`, `template_id_gate.py`, `emoji_gate.py`.
- Web package: +5 test functions vs v0.163.0.

## 6. Deployed version + verification

- Built + pushed `gitea.dooplex.hu/admin/felhom-controller:0.163.1` (145M) from the clean pushed
  tree (`2c80868`, HEAD == origin/main); deployed to guest 9201 via the bootstrap flow.
- Live: `docker ps` → `…felhom-controller:0.163.1  Up (healthy)`; log →
  `controller_started (info) — Controller elindult (0.163.1)` + `settle-gate: GO … we are 0.163.1`.

## 7. Live validation

Method: **endpoint-level, authenticated** (real session cookie via `POST /login`; browser automation
unavailable on DooPlex), `curl` inside the `felhom-controller` container on guest 9201. The 9201 box
now has 5 launcher apps incl. Docmost (which has no logo asset — the exact reported case).

1. **Launcher monogram (check 1).** On the live `/launcher`: `launch-tile--noimg` appears **5 times,
   all 5 inside `onerror` `classList.add(...)` hooks, 0 in any `class=` attribute** — i.e. no tile
   statically carries the reveal class, so no white letter bleeds through a loaded transparent glyph.
   5 tiles / 5 monogram spans (4 operational + 1 stopped — both branches exercised live). Served
   `style.css` carries `.launch-mono { display: none; inset:0; … }` and
   `.launch-tile--noimg .launch-mono { display: flex; }`.
2. **Placeholder on Biztonsági mentés → Alkalmazások (check 2).** The live `/backups/apps` page's
   **Docmost row now carries `data-fallback="/static/app-placeholder.svg"`** and the canonical 3-step
   chain (4 rows total with the placeholder default) — the reported hidden-icon dead-end is gone.
3. **No regression on Alkalmazások (check 3).** The live `/stacks` page: **all 56 `stack-logo-lg`
   imgs still render** with a fallback — 52 default to `/static/app-placeholder.svg`, 4 infra cards
   keep `/static/infra-logo.svg`. Every card keeps its logo source; no logo vanished.

## 8. Observations (not acted on)

- The four aligned copies (`backups_apps` aligned row, `stacks`, `app_info` hero, `deploy`) share the
  same `onerror` grammar but differ in class/size/data-source, so consolidating them into one partial
  is a possible future cleanup — deliberately NOT done here (backups_apps is gate-exempted because it
  owns its collapse toggle; the task scoped this to chain-grammar alignment only).
- The launcher now has a live stopped tile (a greyed app on 9201), so the stopped-branch reveal hook
  is exercised on real data, not only in the render test.
