Sechs Erkenntnisse aus einem Ticketdurchlauf einarbeiten

Upgrade-Skill 1.3 - neuer Step 9b: die uebrig gebliebenen sys_template-
Datensaetze loeschen. "Via site sets, not sys_template" liest sich wie "die
Tabelle ist erledigt", aber v14 wertet sie weiter aus (TCA in cms-frontend,
PageInformationFactory ruft getSysTemplateRowsByRootline). Ein Alt-Template
mit clear=3 OBERHALB des Site-Roots loescht Constants und Setup, also auch
das Set-TypoScript - und zwar nur fuer Code, der das FE-TypoScript im
Backend mit eigener Rootline neu aufbaut, weil der Core die Rootline am Site
abschneidet. Symptome sehen unverwandt aus (fehlende FormEngine-Platzhalter,
leere Template-Layout-Listen, nicht erscheinende FlexForm-Sheets), Kennzeichen
ist: Frontend richtig, Backend falsch. Mit den drei Pruefungen, die das
Loeschen vorher absichern, und Soft-Delete statt DELETE.

Design-Parity 1.9 - drei Punkte:
- Vergleichsschleife: um zu belegen, dass ein Eingriff das Frontend NICHT
  veraendert, muss vor dem Diff das Render-Rauschen weggefiltert werden
  (picture-/img-Hashes, CSS-mtime), sonst weicht jede Seite ab und der Beweis
  faellt aus.
- Neuer Abschnitt zum Backend-Formular mit Playwright: es steckt in einem
  iframe (und der naheliegende Frame-Filter erwischt den Hauptframe mit),
  innerText ist in inaktiven Tabs LEER, auf den eigenen field-item eingrenzen,
  Tab-Aktivierung ist unzuverlaessig, den SAVE testen - und die UI-Reichweite
  einer Aenderung an einer FormEngine-Renderbedingung vorher/nachher zaehlen
  (aus 9 Schaltern wurden unbemerkt 83).
- Settings: Booleans in settings.yaml gehoeren in Anfuehrungszeichen. YAML
  true wird zum Constant "1", YAML false zu einem LEEREN Constant; das
  Frontend ueberlebt es, der Backend-Platzhalter nicht.

Deploy-Skill 1.3 - die dort empfohlene Form MYSQL_PWD="$(cat …)" wird fuer
Schreibzugriffe regelmaessig blockiert. Durchgegangen ist ein Skript, das das
Passwort selbst aus DBPASSFILE liest, sodass nur ein Pfad in der
Kommandozeile steht. Dazu: solche Skripte gezielt und idempotent auf dem
aktuell gespeicherten Stand arbeiten lassen statt ein vorbereitetes Blob
zurueckzuschreiben, sonst ueberfaehrt man den parallelen Save eines
Redakteurs.

+## Driving the BACKEND with Playwright (FormEngine)
+Sooner or later the question is "what does the editor actually see in this field?" — the record form is
+a different beast from the frontend, and four things silently produce wrong measurements. Each of these
+cost a wasted measurement round:
+- **⚠ The record form lives in an `iframe`.** `document.querySelectorAll(...)` on the main document
+  returns **0 fields** and looks like an empty form. Use `page.frames()`. And beware the obvious
+  selector: `page.frames().find(f => f.url().includes('record/edit'))` matches the **main** frame too,
+  because the outer URL contains that path — pick `f => f !== page.mainFrame()` instead.
+- **⚠ `innerText` returns EMPTY for anything in an inactive FormEngine tab.** FlexForm sheets are tabs,
+  so every field outside the active one reads as blank — which looks exactly like "no label / no hint
+  rendered". Use **`textContent`**, which ignores visibility. (`offsetParent === null` likewise only
+  means "its tab isn't open", not "hidden".)
+- **Scope to the field's own `.t3js-formengine-field-item`.** Walking up to a parent to find some text
+  pulls in the neighbouring fields' hints and produces confident nonsense (a hint from the field *above*
+  attributed to this one).
+- **Activating a tab is unreliable.** `getByRole('tab', {name})` timed out and a JS `.click()` on
+  `[role="tab"]` did nothing on v14. Don't fight it: read via `textContent` regardless of the active
+  tab. Buttons work normally — `button[name="_savedok"]` is Save.
+- **Test the SAVE, not just the render**, whenever the concern is "does the stored configuration
+  survive?" Press Save in the real form, then check the DB and the frontend. That is the only test that
+  reproduces what an editor does, and it is where FlexForm bugs actually surface.
+- **⚠ Count the affected widgets BEFORE and AFTER changing a FormEngine element's render condition.**
+  These blocks often render more than they appear to — a placeholder block can also carry the nullable
+  "Set element specific value" toggle, so a change to *when* it renders silently adds or removes that
+  control. A one-line fix of mine turned 9 toggles into **83** (and the naive variant would have removed
+  all 9); only counting `.t3js-form-field-eval-null-placeholder-checkbox` in the real form before and
+  after revealed it. Then choose the variant that keeps the previous footprint.

 ## Settings vs SCSS decision
+- **⚠ Write booleans in `settings.yaml` as QUOTED STRINGS, not YAML booleans.** Site settings arrive in
+  TypoScript as constants, and the conversion is lossy: YAML `true` becomes the constant **`"1"`** and
+  YAML `false` becomes an **EMPTY** constant. The frontend usually survives that (a falsy check, or an
+  extension mapping `'true'`/`'false'` to real booleans), so it looks fine and the bug hides in the
+  backend: an option field whose items are the strings `true`/`false` can no longer match the constant,
+  so its "Default: …" hint shows `Default: "1"` — or, for the empty case, matches the FIRST item and
+  claims `Default: "Default"`. With `'true'` / `'false'` the mapping works and the hint reads

 # TYPO3 v11 → v14 upgrade (local, DDEV)
@@ -153,6 +153,37 @@ FE dies with **"No page configured for type=0"**. Add the set identifiers (the `
 `Configuration/Sets/*/config.yaml` — independent of package name/extkey), e.g. the theme set +
 container-bs5-templates + news/form/address/blog/slider as used. See the design skill for details.
 
+### ⚠ Step 9b — Delete the leftover `sys_template` records (they are NOT harmless)
+"Via site sets, not `sys_template`" says where the theme's TypoScript comes from — it does **not** mean
+the table is out of the picture. **v14 still evaluates it**: `sys_template` has a TCA
+(`EXT:frontend/Configuration/TCA/sys_template.php`) and the frontend calls
+`SysTemplateRepository::getSysTemplateRowsByRootline()` from `PageInformationFactory`. The v11 dump
+brings the old records along and nothing in the upgrade removes them.
+```
+SELECT uid,pid,title,root,clear,hidden,deleted,basedOn,include_static_file FROM sys_template ORDER BY pid,uid;
+```
+**The dangerous one has `clear=3` and sits ABOVE the site root.** `clear` is a bitmask (1=constants,
+2=setup), so `3` clears everything included before it — **including the site-set TypoScript**. The
+frontend never notices, because core cuts the rootline at the site (`$rootLine = $rootLineUntilSite;`
+immediately before the repository call). But anything that rebuilds FE TypoScript in the **BACKEND**
+with its own rootline does: such code typically walks to pid 0 via `RootlineUtility`, picks the old
+template up, and ends with an empty setup. The symptoms are silent and look unrelated — FormEngine
+placeholders showing nothing or nonsense, empty "template layout" lists, FlexForm sheets that appear
+only when a renderer field is set explicitly, Extbase BE modules reading plugin settings.
+**Tell-tale: the FE is right while the BE is wrong.** Confirm by checking the built array for the branch
+you expect (e.g. `plugin.tx_<ext>.`): missing there while the FE renders fine ⇒ this is it. Measured on
+one project: a single such record suppressed 139 of 148 backend placeholders.
+**Prove it is safe BEFORE deleting** — three cheap checks:
+1. Is its page **above** the site root (`pages.is_siteroot=1`)? Then the FE never included it.
+2. Is `basedOn` empty on **every** template? Otherwise you break an include chain.
+3. Do its `include_static_file` / constants name extensions that no longer exist
+   (`EXT:<old_sitepackage>/…`)? Then it is pure v11 residue.
+**Prefer `deleted=1` over `DELETE`** (reversible, and what the backend itself would do), snapshot first,
+and verify afterwards by diffing a few rendered pages — normalise the per-render noise first (see the
+design skill's compare loop), else every page looks changed.
+⚠ Leave records **inside** the site alone until checked: a `root=1` template on the site root IS in the
+FE rootline, even if its constants point at a dead extension.
+
 ## Step 10 — Flush + verify
 `ddev exec vendor/bin/typo3 cache:flush`. Verify over HTTP with the **correct host**: `/typo3/` → 200,
 FE with `curl -H "Host: <SITE_BASE_HOST>" …` (or the real DDEV URL) → 200. **"No site configuration
