# Etappe 4d – Designsystem: Theme-Optionen und Schriften – Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Der KI-Assistent liest und ändert die Design-Theme-Optionen von Divi (Schriften, Größen, Layout – `lit/divi-theme-options-get`, `lit/divi-theme-options-update`), lädt eigene Schriftdateien von einer URL hoch (`lit/divi-fonts-upload`), bekommt bei unbekannten Schriftnamen Vorschläge (auch bei Schrift-Variablen), und kann Snapshots des Bereichs `theme_options` wiederherstellen (`lit/divi-design-restore`) – mit Probelauf, `confirm`, Snapshot (Theme-Optionen) und Zurücklesen.
**Architecture:** Die 4a-Pipeline `DesignChange` bleibt unverändert; neu sind die `DesignArea` `ThemeOptionsArea` mit reinen Klassen (`ThemeOptionSpec`, `ThemeOptionBook`, `ThemeOptionDiff`, `FontSuggest`) und drei kleinen Divi-Adaptern (`ThemeOptionsAdapter`, `FontCatalog`, `FontInstaller`) mit eigenen Fähigkeiten (`theme-option-read`, `theme-option-write`, `font-upload`). Divis Customizer-Standards und -Bereiche stehen nur als Literale in `et_divi_customizer_theme_settings()`; sie werden als Tabelle (`ThemeOptionSpec`) nachgebaut und über einen Mirror mit Fingerabdruck abgesichert. Der Font-Upload ist KEIN Pipeline-Bereich (keine Snapshots, Spec A2): eigener Probelauf/`confirm`-Ablauf, Download über einen aus `MediaImporter` herausgelösten, geteilten `RemoteFileFetcher`, Installation über Divis `FontsUtility::font_add()` im Prozess (`action: wp_handle_upload_rest`, wie Divis eigener KI-Pfad).
**Tech Stack:** PHP ≥ 8.1, WordPress 7.x, Divi 5.15.1 (`et_update_option`/`et_delete_option`, Customizer-Sanitizer, `et_builder_get_fonts`/`_google_fonts`/`_websafe_fonts`/`_custom_fonts`, `FontsUtility::font_add/font_remove`, `HooksRegistration::check_filetype_and_ext_font`, `et_pb_is_allowed` – nur über die drei neuen Adapter), PHPUnit 9.6 + Brain Monkey + Mockery, phpcs (WPCS, PHPCompatibilityWP), DDEV + bash/jq-Smokes.
**Spec:** `docs/superpowers/specs/2026-10-16-etappe-4-designsystem-design.md` (§3, §4, §5, §8, §10, §11, §13, §14 Schritt 7), Entscheidungen `docs/superpowers/notes/2026-09-28-etappe-4-entscheidungen-entwurf.md` (G3, G6, G10, A1, A2, A8, A9 – verbindlich, soweit unten nicht durch Rulings W1–W14 geändert), Datenformate `docs/superpowers/notes/2026-09-28-etappe-4-divi-formate.md` §4 und der Nachtrag 4d in Task 11, Recherche 5.15.1: `docs/superpowers/notes/2026-10-19-etappe-4d-divi-recherche.md` (Task 11 legt sie ab; bis dahin die Kopie `…/scratchpad/research-4d-divi.md` des Planers – die Task-Autoren haben sie gelesen), Plan 4c (`2026-10-19-etappe-4c-farben-variablen.md`) als Vorbild; der Code ist maßgeblich, wo er von den Plänen abweicht.
**Voraussetzung:** Branch `etappe-4` (= `main`), Stand 2307027 (4a, 4b, 4c fertig), 3121 Unit-Tests grün (`composer test`), `composer lint` sauber.
**Teil von Etappe 4:** 4a, 4b, 4c (fertig) → **4d (dieser Plan)** → 4e Schleifen-Inhalte, Guides, Audit, Version.
## Global Constraints
- **Dateien nur im Plugin-Verzeichnis** `/home/janniclas/Projekte/WordPress/wp-content/plugins/WP-LIT-MCP` anlegen oder ändern. Integrationsskripte stellen im EXIT-Trap alles wieder her, was sie ändern (`et_divi` byte-genau über serialize/base64, hochgeladene Schriften inkl. Dateien über `FontsUtility::font_remove`, Seiten, Variablen).
- PHP ≥ 8.1 ohne 8.2+-Features; WordPress ≥ 6.9; Divi 5.15.1. Namespace `LIT\MCP\` → `src/`, PSR-4, eine Klasse pro Datei, jede Datei mit `defined('ABSPATH') || exit;`, `declare(strict_types=1);`, höchstens 120 Zeichen je Zeile. Nach jedem Task `composer test` und `composer lint` sauber (`composer test` = `php -d memory_limit=512M vendor/bin/phpunit`).
- **Divi-Grenze (Divi-Absicherung §3):** Divi-Aufrufe nur in Klassen aus `DiviAdapters::CLASSES` mit Manifest; jedes Divi-Symbol steht mit Fähigkeiten im Manifest; `DiviBoundaryTest` und `DiviFeatureAssignmentTest` bleiben grün (die angepasste Tabelle gehört in denselben Task wie die Manifest-Änderung); neue Signaturen: `fingerprints.json` über `wp lit-mcp divi-check --update-reference` in DDEV neu erzeugen (Befehl und Prüfung wie in Task 2 des Plans 4c). Alle übrigen neuen Klassen sind **reines PHP** ohne WordPress- und Divi-Aufrufe; Ausnahmen nennt der Task ausdrücklich.
- **Pipeline (Spec §4):** Theme-Optionen laufen durch `DesignChange::run()` (Rechte → Eingabe prüfen, alle Fehler gesammelt als `validation_failed` mit Feldpfaden → Probelauf mit `diff`, `design_rev`, `warnings` → mit `confirm: true` Sperre, Snapshot `theme_options`, Schreiben, Zurücklesen + `verify`, Protokoll). Der Font-Upload nutzt die Pipeline nicht (kein Snapshot, A2), hat aber Probelauf + `confirm`, Rechte vorab, Rollback und Protokoll.
- **Werte:** Jeder Wert einer Theme-Option wird vom Plugin geprüft (`ThemeOptionSpec::check`: Typ, Bereich, Auswahl) UND durch Divis eigenen Customizer-Sanitizer des Schlüssels geschickt (`ThemeOptionsAdapter::sanitize`); `false` oder ein vom Eingabewert abweichendes Ergebnis ist ein Validierungsfehler (Divi würde `false` stillschweigend speichern bzw. runden). Die fünf Hauptfarben, Button-Standards (`all_buttons_*`), Logo und SEO bleiben außen (G3, A8).
- **Rechte:** Theme-Optionen schreiben und Restore: `edit_theme_options` **und** `et_pb_is_allowed('theme_customizer')` (Divis Customizer-Regel); Lesen (`theme-options-get`): wie `lit/divi-design-system` (`edit_posts`). Font-Upload: `upload_files` **und** `edit_theme_options` **und** `et_pb_is_allowed('custom_fonts_management')` (Divis eigene Regel `CustomFontController::store_permission()` plus die Plugin-Regel; Spec §10 nannte irrtümlich `use_visual_builder`).
- **Exposition:** Neue Tools sind indirekt (über `mcp-adapter-execute-ability`), Gruppe `divi`, Annotations wie die Preset-Tools (`write`/`destructive`); Texte nennen indirekte Tools `lit/<name>` (ToolNamingTest); `docs/guides/overview.md` „Direkt sichtbar:“ bleibt unverändert; Guides folgen gesammelt mit 4e.
- **Sprache:** Meldungen, Hinweise, Beschreibungen auf Deutsch mit echten Umlauten; neutral „KI-Assistent“, „MCP-Client“.
- **Tests:** Abilities über `LIT\MCP\Tests\Unit\TestCase` (Brain Monkey + Mockery, `assertToolError`); vorbelegte Stubs (`wp_json_encode`, `is_wp_error`, `absint`, `wp_slash`, `wp_unslash`, `sanitize_text_field`) nie mit `Functions\expect()` prüfen. Reine Klassen erben von `PHPUnit\Framework\TestCase`. TDD: Test zuerst, RED-Lauf, Code, GREEN. Adapter-Tests ersetzen Divi-Klassen per `Mockery::mock('alias:…')` mit `@runInSeparateProcess` (Vorbild `GlobalColorsAdapterTest`). Integration: `cd /home/janniclas/Projekte/WordPress && timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/<skript>.sh` (läuft nur mit deaktivierten Plugins `postlos` und `asynclistry`; vorher Zustand mit `ddev exec wp plugin list` notieren und danach wiederherstellen).
- **Kein clean-code-review-Skill je Task** (die globale CLAUDE.md-Regel zieht sonst die Antwort des Implementierers an sich); der Gesamtreview folgt am Ende (Task 11).
- Commits: `git commit -m "<Nachricht>" -m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"` mit dem Namen des ausführenden Modells; nur die Dateien des Tasks stagen.
## Entscheidungen für 4d (Rulings, verbindlich)
- **W1 Drei Fähigkeiten:** `DiviFeature::ThemeOptionRead` (`theme-option-read`, „Theme-Optionen lesen“), `ThemeOptionWrite` (`theme-option-write`, „Theme-Optionen schreiben“, schreibend), `FontUpload` (`font-upload`, „Schriften hochladen“, schreibend). `ThemeOptionsArea::feature()` = `ThemeOptionWrite`. Der Mirror `customizer-typography` (Standards/Bereiche der 20 Settings) trägt `theme-option-read` und `-write`; die Schriftlisten-Aufrufe tragen `theme-option-write`, `font-upload` und `variable-write` (die Schrift-Variablen werden gegen dieselbe Liste geprüft; ein Bruch sperrt bewusst alle drei).
- **W2 Whitelist (Spec §8.1, G3):** `heading_font`, `body_font`, `primary_nav_font`, `secondary_nav_font`, `heading_font_weight`, `body_font_weight`, `body_font_size`, `tablet_body_font_size`, `phone_body_font_size`, `body_header_size`, `tablet_header_font_size`, `phone_header_font_size`, `body_font_height`, `body_header_height`, `body_header_spacing`, `body_header_style`, `content_width`, `gutter_width`, `section_padding`, `row_padding`. Standards, Bereiche und Sanitizer-Namen je Schlüssel stehen in der Recherche (Tabelle A) und werden in `ThemeOptionSpec` als Literale nachgebaut; der Mirror auf `et_divi_customizer_theme_settings()` (`functions.php`) sichert sie. `shortcut:` der Mirror hasht die ganze Funktion und schlägt bei jeder Customizer-Änderung an; bei zu häufigem Anschlagen auf einen engeren Ausschnitt umstellen (im Code kommentieren).
- **W3 Unset statt `'none'`:** Ein Schlüssel ist „nicht gesetzt“ = Divi-Standard. Der Eingabewert `null` setzt zurück (Divi: `et_delete_option`); `'none'` und `false` werden abgelehnt (Divi speichert die Standardschrift als `false`, ein gespeichertes `'none'` wäre in Divi 5 ein echter Schriftname). Tablet-/Phone-Größen erben, solange sie nicht gesetzt sind (effektiver Standard = der größere Wert); `get` nennt den effektiven Wert und `default`.
- **W4 Bereiche prüft das Plugin:** Divis Sanitizer (`absint`, `intval`, `floatval`, Auswahl-Sanitizer → `false`) klemmen nicht; `ThemeOptionSpec` prüft min/max/step/choices der Customizer-Controls. `body_header_style` nimmt genau einen Wert (`italic`, `uppercase`, `underline`) oder `null` (Divis Sanitizer lehnt Kombinationen ab). Zahlen dürfen als Zahl oder Ziffern-String kommen; gespeichert wird der Typ, den Divis Sanitizer liefert (int/float/String).
- **W5 Schriftnamen:** gültig ist der exakte Familienname (Groß-/Kleinschreibung) aus `array_merge(et_builder_get_custom_fonts(), et_builder_get_fonts())` (so prüft Divis Sanitizer). Unbekannt → `validation_failed` mit bis zu 5 ähnlichen Namen (`FontSuggest`, ohne Beachtung der Groß-/Kleinschreibung: Präfix, Teilstring, `levenshtein`). Die Liste wird je Request einmal geladen (`et_builder_get_google_fonts()` lädt 1,3 MB und kann einmal je Tag einen HTTP-Abruf auslösen). Gilt für `heading_font`, `body_font`, `primary_nav_font`, `secondary_nav_font` und Variablen vom Typ `fonts`. Schriftnamen in Preset-/Modul-Attributen werden in 4d NICHT geprüft (Folgepunkt für 4e, in der Notiz festgehalten).
- **W6 Snapshot `theme_options`:** `raw` = genau die vorhandenen Whitelist-Schlüssel aus `get_option('et_divi')` mit Rohwert und Typ (`array<string, int|float|string|false>`); ein fehlender Schlüssel fehlt im Array. `ThemeOptionBook` normalisiert (nur Whitelist, Schlüsselreihenfolge fest) und liefert `rev()`. Schreiben/Restore: Schlüssel im neuen Bestand → `et_update_option`, Whitelist-Schlüssel, die im neuen Bestand fehlen → `et_delete_option`; danach die Caches wie ein Customizer-Speichern (`ET_Core_PageResource::remove_static_resources('all', 'all')` und `et_pb_force_regenerate_templates()`). Zurücklesen über `get_option('et_divi')` (nicht über `GlobalData::get_customizer_fonts()`, das `static` cacht). Restore ist ein vollständiges Ersetzen der Whitelist (`mayRemove = true`). Lost-Update-Risiko von `et_update_option` (schreibt das ganze Array aus dem Request-Global) ist dokumentiert; `design_rev` und Sperre mindern es.
- **W7 Keine Fundstellen:** Theme-Optionen haben keinen Seitenbezug; der Probelauf liefert kein `affected` und die Warnung „wirkt auf die gesamte Website“ (bei Schriften zusätzlich „wirkt auch auf den Builder“). `DesignPlan::usages` bleibt `null`.
- **W8 Font-Upload-Weg:** `FontInstaller::install()` ruft `FontsUtility::font_add($files, $name, $settings, ['action' => 'wp_handle_upload_rest'])` mit Temp-Dateien (`wp_tempnam`, wie `AiAgentImageUtility::install_to_custom_fonts()`); jede Datei vorab durch `HooksRegistration::check_filetype_and_ext_font()`; nach `font_add` werden die gelieferten `font_file`-Schlüssel gegen die Eingabe verglichen (Divi meldet Teilerfolg als Erfolg) – Abweichung → `FontsUtility::font_remove($name)` und Fehler. Statt eines Nachbaus des `et_uploaded_fonts`-Eintrags (Spec §8.2) ein Mirror `font-install` auf `AiAgentImageUtility::install_to_custom_fonts` (Aufrufkonvention). Erlaubte Formate: `woff2`, `woff`, `ttf`, `otf` (kein `eot`); Gewichte `all` oder Liste aus `100…900` (Plugin prüft, Divi nicht); `generic_family` aus `serif|sans-serif|monospace|cursive|fantasy` (Standard `sans-serif`; Divi prüft nicht).
- **W9 Font-Namen und -Dateien:** Name: 1–100 Zeichen, nur `A–Z a–z 0–9`, Leerzeichen, `_`, `-` (Divi entfernt andere Zeichen stillschweigend – das Plugin lehnt ab und nennt den bereinigten Namen), nicht in Googles, Web-Safe- oder bereits hochgeladenen Schriften (ohne Beachtung der Groß-/Kleinschreibung; strenger als Divi). Dateien: höchstens `min(Limits::uploadBytes(), 5 MB)` je Datei (A9), 1–4 Dateien (je Format höchstens eine), Magic Bytes (`FontSignature`: `wOF2`, `wOFF`, `00 01 00 00`/`true` = ttf, `OTTO` = otf) müssen zur Endung der Eingabe passen; URL-Regeln (nur öffentliche Hosts, Weiterleitungen geprüft, Zeitlimit) wie `lit/media-upload-from-url` über den geteilten `RemoteFileFetcher`.
- **W10 Probelauf des Uploads:** ohne `confirm` lädt das Tool die Dateien wirklich herunter (nur Temp-Dateien, danach gelöscht), prüft alles und antwortet mit `Errors::confirmRequired` (Name, Dateien mit Format/Größe/SHA-256, Gewichte, Familie, „wirkt auf …“-Hinweis). Mit `confirm: true` lädt es erneut, prüft erneut und installiert; das Protokoll nennt die SHA-256-Werte. Kein Snapshot; Rollback bei Fehler über `font_remove`.
- **W11 Restore:** `DiviDesignRestoreAbility` bekommt `ThemeOptionsRestorePlanner` (`area()` `theme_options`); die Meldung „Theme-Optionen folgen mit Etappe 4d“ entfällt (ein unbekannter Bereich bleibt `unsupported`); Rechte und Fähigkeiten wie beim Schreiben.
- **W12 Schrift-Variablen:** `DiviVariablesSetAbility` prüft Variablen vom Typ `fonts` zusätzlich gegen `FontCatalog` (W5); `VariableValue` bleibt rein (die Listenprüfung liegt in der Ability, `VariableValue.php:12` „folgt mit 4d“ wird berichtigt).
- **W13 Divi-Beschränkungen als Grenzen dokumentieren:** `et_get_option`-/`et_update_option`-Lost-Update, `body_header_style`-Einzelwert, fehlende Bereichsprüfung in Divi, `font_add`-Teilerfolg, `remove_static_resources` wirkungslos ohne angemeldeten Benutzer (der Prozess hat einen, Smokes laufen mit `--user`).
- **W14 Rechte-Texte:** `DesignRights::themeOptions(DesignSystemWriter, ThemeOptionsAdapter)` und `DesignRights::fonts(FontCatalog)` entsprechen den Rechten oben; Fehlertexte nennen das fehlende Recht und die Divi-Rolle („Theme-Anpassung“/„Eigene Schriften verwalten“).

### Task 1: Fähigkeiten `ThemeOptionRead`, `ThemeOptionWrite` und `FontUpload` (W1)
Drei neue Fähigkeiten, damit ein Bruch des Customizer-Nachbaus, der Schriftlisten oder des Font-Uploads nur die jeweils betroffenen Tools sperrt. Geprüft mit `grep -rn "VariableWrite\|variable-write\|13 \|dreizehn\|thirteen" src tests docs` und einem Lauf der ganzen Suite mit den drei neuen Fällen (Stand 2307027, Kopie): nur drei Tests brechen – zwei in `DiviFeatureTest` (zählen und listen die Fälle exakt) und `DiviFeatureAssignmentTest::testEveryFeatureIsServedByAtLeastOneRequirement` (jede Fähigkeit braucht eine Manifest-Anforderung; die kommen erst mit den Adaptern in Task 2). `FeatureOverviewTest`, `DiviEnvironmentComponentTest`, `CompatibilityMatrixTest`, `ReleaseGateTest`, `DiviCheckCommandTest::testEveryFeatureGetsOneLine` und alle übrigen rechnen mit `count(DiviFeature::cases())` oder nennen nur einzelne Fähigkeiten und bleiben grün; `DiviToolFeaturesTest` nennt nur Tool-Tabellen (die neuen Tools folgen mit Task 9). Außerhalb der Unit-Tests zählt nur `tests/Integration/divi-release-smoke.sh` die Fähigkeiten (Liste der IDs, „thirteen“, `= "13"`); `docs/guides` nennt keine Zahl.
**Wegen des Zuordnungstests hat Task 1 keinen eigenen Commit:** seine Dateien gehen mit dem Commit von Task 2 (Step 14) ins Repo (wie Tasks 1/2 des Plans 4c). Bis dahin ist genau `DiviFeatureAssignmentTest::testEveryFeatureIsServedByAtLeastOneRequirement` rot.
**Files:**
- Modify: `src/Integrations/Divi/Release/DiviFeature.php` (drei Fälle, `isWrite()`, `label()`, Docblock von `isWrite()`)
- Modify: `tests/Unit/Integrations/Divi/Release/DiviFeatureTest.php`
- Modify: `tests/Integration/divi-release-smoke.sh` (16 statt 13 Fähigkeiten; läuft erst nach Task 2 grün, weil vorher die Signatur-Referenzen der neuen Aufrufe fehlen)
**Interfaces:**
- Consumes: `DiviFeature` (vorhanden).
- Produces: `DiviFeature::ThemeOptionRead = 'theme-option-read'` („Theme-Optionen lesen“, `isWrite() === false`), `DiviFeature::ThemeOptionWrite = 'theme-option-write'` („Theme-Optionen schreiben“, `isWrite() === true`), `DiviFeature::FontUpload = 'font-upload'` („Schriften hochladen“, `isWrite() === true`). Reihenfolge der Fälle (bestimmt die Reihenfolge in Status-Tool, Admin-Reiter und `divi-check`): direkt nach `VariableWrite`, vor `LibraryRead`.
- [ ] **Step 1: `DiviFeatureTest` auf sechzehn Fähigkeiten umstellen**
`tests/Unit/Integrations/Divi/Release/DiviFeatureTest.php` vollständig ersetzen:

### Task 2: Adapter `ThemeOptionsAdapter` und `FontCatalog`, Manifest, Fingerabdrücke, `DesignRights` (W1, W2, W5, W6, W13, W14)
Zwei kleine Adapter im Bereich „Designsystem“ – die einzigen Klassen, die Divis Theme-Optionen schreiben bzw. Divis Schriftlisten lesen – mit eigenem Manifest. Geteilte Divi-Aufrufe stehen wie in Plan 4c in **jedem** Manifest, das sie nutzt (`ET_Core_PageResource::remove_static_resources` zusätzlich zu `DiviPages`/`DiviThemeBuilder`, `et_pb_is_allowed` zusätzlich zu `DiviRoles`/`GlobalVariablesAdapter`); `DiviAdapters::calls()` führt jedes Symbol nur einmal (für die Signatur egal), `featuresOf()` gilt je Manifest.
Geprüft an Divi 5.15.1 (`themes/Divi`): die `sanitize_callback` aller 20 Settings in `functions.php` (`et_divi[<key>]`, je Setting gelesen – stimmt mit der Recherche, Tabelle A, überein); `et_sanitize_float_number($number)` (`includes/functions/sanitization.php:7`), `et_sanitize_int_number($number)` (`:16`), `et_sanitize_font_choices($choosen)` (`:59`, `array_merge(et_builder_get_custom_fonts(), et_builder_get_fonts())`, `isset` → case-sensitiv), `et_sanitize_global_font_weight($choosen)` (`:345`), `et_divi_global_font_style($choosen)` (`:358`) – alle 1 Parameter, untypisiert; `et_update_option($option_name, $new_value, …)` (`epanel/custom_functions.php:276`, 2 Pflicht-/6 Parameter, schreibt über das Request-Global `$et_theme_options`), `et_delete_option($option_name)` (`:320`), `ET_Core_PageResource::remove_static_resources($post_id, $owner = 'core', …)` (`core/components/PageResource.php:1398`, 1 Pflicht-/7 Parameter, wirkungslos ohne `edit_posts`), `et_pb_force_regenerate_templates()` (`includes/builder/core.php:3811`, auch auf `customize_save_after`), `et_pb_is_allowed($capabilities, $role = '')` (`:1136`), `et_builder_get_fonts($settings = array())` (`:4730`, ohne Google Fonts nur Web-Safe), `et_builder_get_websafe_fonts()` (`:4783`), `et_builder_get_custom_fonts()` (`:4822`, `(array)` gefiltert), `et_builder_get_google_fonts()` (`:4911`, `[]` bei abgeschalteten Google Fonts, ruft `et_builder_google_fonts_sync()`). Rollen-Editor: `theme_customizer` „Theme Customizer“ (`includes/builder/functions.php:9523`), `custom_fonts_management` „Upload/Remove Fonts“ (`:9595`).
**Mirror auf `functions.php` (Theme-Wurzel, Funktion ohne Namespace):** wird ohne Codeänderung unterstützt. `Mirror::$file` ist relativ zum Theme-Verzeichnis (`DiviReference::current($themeDir)` → `$themeDir . '/' . $file`), `class: null` sucht die Funktion außerhalb jedes Klassenrumpfs; `SourceFingerprint::fromSource()` zählt `if (! function_exists(…)) :`-Blöcke nicht als Klassenrumpf. In der Kopie nachgerechnet: `SourceFingerprint::of('<Divi>/functions.php', 'et_divi_customizer_theme_settings')` → Zeilen 1371–5332, 103 803 Byte Quelltext, Hash `0264fa5a2ba604542e1e1ad0c0339f04c8f4f67297087a0f92954ee63d343fd0`. Die Referenzquelle `tests/Fixtures/divi/reference/customizer-typography.txt` wird damit ~104 KB groß (W2-`shortcut:`, im Manifest kommentiert).
**Sanitizer-Tabelle und Divi-Grenze:** `ThemeOptionsAdapter::SANITIZERS` (öffentliche Konstante, Schlüssel = die 20 Whitelist-Schlüssel in W2-Reihenfolge, Wert = Name des `sanitize_callback`) ist die eine Tabelle; `sanitize()` ruft den Namen dynamisch auf (`$sanitizer($value)`, wie WordPress selbst `sanitize_callback` ruft). Ehrlich bleibt das, weil `DiviTouches` auch String-Literale `'et_…'` als Divi-Namen meldet: ein neuer Divi-Sanitizer in der Tabelle ohne Manifest-Eintrag lässt `DiviBoundaryTest::testAdaptersDeclareExactlyTheDiviNamesTheyUse` scheitern; `absint` (WordPress) ist kein Divi-Name. Die Gegenrichtung („im Manifest, aber nicht benutzt“) prüft `DiviBoundaryTest` nur schwach (die Literale im Manifest selbst zählen als Benutzung) – darum pinnt `ThemeOptionsAdapterTest::testTheSanitizerTableCoversTheWhitelistWithDivisCallsOfTheManifest` die Tabelle: genau die 20 W2-Schlüssel, genau fünf Divi-Sanitizer, jeder als `Call(<name>, 1)` im Manifest. `ThemeOptionSpec` (Task 3) soll seine `KEYS` gegen `array_keys(ThemeOptionsAdapter::SANITIZERS)` testen (siehe `## ABWEICHUNGEN`, B1).
**Unit-Tests ohne Divi:** Alle Divi-Symbole der beiden Adapter sind Funktionen; die Tests ersetzen sie mit Brain Monkey (`Functions\when()`/`Functions\expect()`) und laufen dann mit `@runInSeparateProcess` (Brain Monkey definiert eine fehlende Funktion für den Rest des Prozesses; `DiviRolesTest`, `DiviIntegrationTest`, `GlobalVariablesAdapterTest::testWithoutDiviNobodyManagesVariables` und die neuen `testWithoutDivi…`-Tests verlassen sich auf ihr Fehlen). Ein `Mockery::mock('alias:…')` wie in `GlobalColorsAdapterTest` ist nicht nötig – es gibt keine Divi-Klasse außer `ET_Core_PageResource`, und die ist der aufzeichnende Stub `tests/Stubs/EtCorePageResource.php` (`$removed`, vom Bootstrap geladen). `get_option` wird wie in `GlobalColorsAdapterTest` ohne eigenen Prozess per `Functions\when()` ersetzt. Beide Adapter sind **nicht `final`**, damit `DesignRightsTest` und die Tasks 4–8 sie mit Mockery ersetzen können.

- Modify: `tests/Unit/Integrations/Divi/Design/DesignRightsTest.php`
**Interfaces:**
- Consumes: `Manifest`, `Call`, `Mirror`, `DiviAdapter`, `DiviAdapters::CLASSES`, `ReleaseGate::assertFeature()`, `DiviLocked`, `Errors::forbidden()`, `DesignSystemWriter` (alle vorhanden), `DiviFeature::ThemeOptionRead`/`ThemeOptionWrite`/`FontUpload` (Task 1); Tests: `LIT\MCP\Tests\Unit\TestCase` (`assertToolError`, Stub `absint`), `ReleaseMatrices::uniform(ReleaseState, string)`, Brain Monkey `Functions\when()`/`expect()`, Stub `\ET_Core_PageResource::$removed`.
- Produces:
- `class ThemeOptionsAdapter implements DiviAdapter` – `manifest()`: Bereich `Manifest::DESIGN`; Aufrufe `et_sanitize_font_choices` (1), `et_sanitize_global_font_weight` (1), `et_sanitize_float_number` (1), `et_sanitize_int_number` (1), `et_divi_global_font_style` (1), `et_update_option` (2), `et_delete_option` (1), `ET_Core_PageResource::remove_static_resources` (2), `et_pb_force_regenerate_templates` (0), `et_pb_is_allowed` (1); Schlüssel `et_divi`; Mirror `customizer-typography` (`functions.php`, `et_divi_customizer_theme_settings`, `class: null`, Fähigkeiten `[ThemeOptionRead, ThemeOptionWrite]`); Vorgabe `[ThemeOptionWrite]`. `public const SANITIZERS` (siehe oben). `read(): array<string, int|float|string|false>` – die vorhandenen Whitelist-Schlüssel aus `get_option('et_divi')` in `SANITIZERS`-Reihenfolge, Werte anderen Typs (Array, `null`, `true`) fehlen. `sanitize(string $key, mixed $value): mixed` – Divis Sanitizer des Schlüssels, Nicht-Skalare → `false` ohne Divi-Aufruf, unbekannter Schlüssel → `InvalidArgumentException('not a theme option of the whitelist: <key>')`. `write(array $set, array $unset): array` – `ReleaseGate::assertFeature(ThemeOptionWrite)`, fremde Schlüssel → `InvalidArgumentException` (nichts geschrieben), dann `et_update_option` je `$set`-Schlüssel, `et_delete_option` je `$unset`-Schlüssel, `\ET_Core_PageResource::remove_static_resources('all', 'all')`, `et_pb_force_regenerate_templates()`, Zurücklesen über `read()`; weicht ein Wert ab (`!==`) oder ist ein `$unset`-Schlüssel noch da → `RuntimeException('theme options not written: <keys>')`; sonst liefert es `read()`. `canCustomize(): bool` = `function_exists('et_pb_is_allowed') && et_pb_is_allowed('theme_customizer')`.
- `class FontCatalog implements DiviAdapter` – `manifest()`: Aufrufe `et_builder_get_fonts` (0), `et_builder_get_custom_fonts` (0), `et_builder_get_google_fonts` (0), `et_builder_get_websafe_fonts` (0) mit der Vorgabe `[ThemeOptionWrite, FontUpload, VariableWrite]` (W1), `et_pb_is_allowed` (1) nur `[FontUpload]`; Schlüssel `et_uploaded_fonts`, `et_google_fonts_cache`, `et_google_api_settings` (Dokumentation: die Optionen hinter Divis Listen, gelesen nur über Divis Funktionen). `names(): list<string>` – Schlüssel von `et_builder_get_custom_fonts()` dann `et_builder_get_fonts()` (genau Divis Sanitizer-Liste), je Instanz einmal geladen; `uploaded(): list<string>` und `reserved(): list<string>` (Google, Web-Safe, hochgeladen) je Aufruf frisch; `has(string $name): bool` exakt (`in_array(…, true)`); `canManage(): bool` = `et_pb_is_allowed('custom_fonts_management')`, ohne Divi `false`. Nicht-Array-Listen (kaputter Filter) zählen als leer; numerische Familiennamen bleiben Strings.
- `DesignRights::themeOptions(DesignSystemWriter $writer, ThemeOptionsAdapter $options): ?WP_Error` – `edit_theme_options`, dann `canCustomize()`; `$writer` wird nicht gefragt (siehe `## ABWEICHUNGEN`, B2). Meldungen: „Theme-Optionen ändern erfordert das Recht, das Design der Website anzupassen (edit_theme_options).“ / „Die Divi-Rolle dieses Kontos erlaubt die Theme-Anpassung nicht; ohne sie ändert LIT MCP keine Theme-Optionen.“ (Hinweis Rollen-Editor).
- `DesignRights::fonts(FontCatalog $fonts): ?WP_Error` – `upload_files` („Schriften hochladen erfordert das Recht, Dateien hochzuladen (upload_files).“), `edit_theme_options` („Schriften hochladen erfordert das Recht, …“), `canManage()` („Die Divi-Rolle dieses Kontos erlaubt „Eigene Schriften verwalten“ nicht; ohne das Recht lädt LIT MCP keine Schriften hoch.“, Hinweis Rollen-Editor).
- `presets()`, `colors()`, `variables()` verhalten sich unverändert (gleiche Texte; `designer()` nutzt jetzt `themeRight()`).

- [ ] **Step 12: Signatur-Referenzen und Nachbau-Fingerabdruck in DDEV erzeugen**
`wp lit-mcp divi-check --update-reference` (`src/Integrations/Divi/Cli/DiviCheckCommand.php::updateReference()`) verlangt einen Administrator, schreibt nur, wenn außer „Fingerabdrücke nachgebauter Divi-Funktionen“ alle Prüfschritte grün sind (Manifeste: die zwölf neuen Aufrufe existieren mit passender Argumentzahl – geprüft über `getNumberOfRequiredParameters() <= args <= getNumberOfParameters()`; die fehlende Signatur-Referenz und der neue Nachbau sind nur `reference-missing`-Probleme), und nur in einer Entwicklungskopie mit `tests/` (`DiviReference::sourceDir()`). Es schreibt zuerst die Referenzquellen aller Nachbauten (die sechs alten unverändert, neu `customizer-typography.txt`), zuletzt `fingerprints.json` (Nachbauten + `sig:` jedes Aufrufs aus `DiviAdapters::calls()`).
Run:
```bash
cd /home/janniclas/Projekte/WordPress
ddev start
ddev exec wp plugin list --status=active --field=name
ddev exec bash -c 'wp --user="$(wp user list --role=administrator --field=user_login | head -1)" lit-mcp divi-check --update-reference'
```
Expected: die Prüfschritte mit `✓` (`Fingerabdrücke nachgebauter Divi-Funktionen` darf `✗` sein), dann `Referenz aktualisiert (7 Fingerabdrücke, 44 Signaturen). Smoke-Skripte laufen lassen, dann committen.` und die Fähigkeiten-Matrix; Exit-Code 0. Bricht WP-CLI mit Monolog-/Deprecation-Ausgaben ab, vorher `ddev exec wp plugin deactivate postlos asynclistry` und danach wieder `ddev exec wp plugin activate postlos asynclistry` (nur, wenn die Liste oben sie als aktiv zeigte).
Ergebnis prüfen:
```bash
cd /home/janniclas/Projekte/WordPress/wp-content/plugins/WP-LIT-MCP
git diff -U0 src/Integrations/Divi/Release/fingerprints.json | grep '^[-+] '
git status --short tests/Fixtures/divi/reference
jq -r 'keys[]' src/Integrations/Divi/Release/fingerprints.json | grep -c '^sig:'
jq -r '."customizer-typography"' src/Integrations/Divi/Release/fingerprints.json
```
Expected: genau dreizehn `+`-Zeilen und keine `-`-Zeile – `"customizer-typography": "0264fa5a2ba604542e1e1ad0c0339f04c8f4f67297087a0f92954ee63d343fd0"` und die `sig:`-Schlüssel `et_builder_get_custom_fonts`, `et_builder_get_fonts`, `et_builder_get_google_fonts`, `et_builder_get_websafe_fonts`, `et_delete_option`, `et_divi_global_font_style`, `et_pb_force_regenerate_templates`, `et_sanitize_float_number`, `et_sanitize_font_choices`, `et_sanitize_global_font_weight`, `et_sanitize_int_number`, `et_update_option` (je `"sig:<name>": "<sha256>"`); `?? tests/Fixtures/divi/reference/customizer-typography.txt` als einzige Änderung unter `reference` (beginnt mit `function et_divi_customizer_theme_settings( $wp_customize ) {`, ~104 KB); `44`; der Hash oben (in der Kopie mit `SourceFingerprint` über das installierte `functions.php` nachgerechnet). Ändert sich ein anderer Schlüssel oder weicht der Hash ab, **nicht committen**, sondern prüfen (installiertes Divi ≠ 5.15.1 oder eine Divi-Signatur hat sich geändert).
- [ ] **Step 13: Gesamtlauf, Lint, Freigabe-Smoke**
Run: `composer test && composer lint`
Expected: `OK (3142 tests, …)` (in der Kopie mit nachgestellten Referenzen: `OK (3142 tests, 19539 assertions)`), Lint sauber.
Run: `cd /home/janniclas/Projekte/WordPress && timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-release-smoke.sh`
Expected: `ALL CHECKS PASSED` – u. a. `ok - manifests and fingerprints match the installed Divi` (keine `reference-missing`-Probleme für die neuen Aufrufe und den Nachbau) und `ok - lit-site-status: sixteen features released (code), each with its tools`. Läuft nur mit deaktivierten Plugins `postlos` und `asynclistry` (vorher `ddev exec wp plugin list` notieren, danach den Zustand wiederherstellen).
- [ ] **Step 14: Commit (Tasks 1 und 2)**
```bash
cd /home/janniclas/Projekte/WordPress/wp-content/plugins/WP-LIT-MCP

### Task 3: Reine Klassen `ThemeOptionSpec`, `ThemeOptionBook`, `ThemeOptionDiff`, `FontSuggest`
Der reine Bestand der Theme-Optionen (W2, W3, W4, W6, W5): die Tabelle der 20 Customizer-Einstellungen mit Prüfung, Normalisierung und Vererbung (`ThemeOptionSpec`), der unveränderliche Bestand mit `rev()` (`ThemeOptionBook`), der Diff mit Zusammenfassung (`ThemeOptionDiff`) und die Namensvorschläge für unbekannte Schriften (`FontSuggest`). Kein WordPress, kein Divi: die Klassen brauchen weder Adapter noch Manifest und sind unabhängig von Task 1 und 2 (Task 4 und 5 setzen sie voraus). Vier Teilblöcke, je eine Klasse und ein Commit; 3c baut auf 3b auf (`ThemeOptionDiffTest` nutzt `ThemeOptionBookTest::stored()`), 3b auf 3a. Die Werte der Tabelle sind gegen Divis `et_divi_customizer_theme_settings()` (`functions.php` 1903–2561) nachgeprüft: Standards, `min`/`max`/`step` und Sanitizer stimmen mit Tabelle A der Recherche überein (z. B. `body_header_spacing` −2…10, `body_font_height` 0,8…3 in 0,1-Schritten, `content_width` 960…1920).
**Files:**
- Create: `src/Integrations/Divi/Design/ThemeOptionSpec.php`, `src/Integrations/Divi/Design/ThemeOptionBook.php`, `src/Integrations/Divi/Design/ThemeOptionDiff.php`, `src/Integrations/Divi/Design/FontSuggest.php`
- Create: `tests/Unit/Integrations/Divi/Design/ThemeOptionSpecTest.php`, `tests/Unit/Integrations/Divi/Design/ThemeOptionBookTest.php`, `tests/Unit/Integrations/Divi/Design/ThemeOptionDiffTest.php`, `tests/Unit/Integrations/Divi/Design/FontSuggestTest.php`
**Interfaces:**
- Consumes: `LIT\MCP\Abilities\Rev::of()` (vorhanden).
- Produces (Namen und Signaturen wie im Schnittstellenvertrag; Verfeinerungen siehe `## ABWEICHUNGEN`):
- `ThemeOptionSpec::KEYS` (20 Schlüssel, Reihenfolge W2), `definition(string): array`, `isKey(string): bool`, `check(string, mixed): ?string`, `normalize(string, mixed): int|float|string`, `effective(string, array): int|float|string|null`. `definition()` und `check()`/`normalize()`/`effective()` werfen `InvalidArgumentException` bei einem Schlüssel außerhalb der Whitelist.
- `ThemeOptionBook::fromDivi(array)`, `data()`, `rev()`, `has()`, `get()`, `with()`, `without()`; `with()` wirft `InvalidArgumentException` bei unbekanntem Schlüssel.
- `ThemeOptionDiff::between(ThemeOptionBook, ThemeOptionBook)`, `summary(array)`.
- `FontSuggest::similar(string, list<string>, int = 5)`.
- Ausgangslage vor dem Task: `composer test` = 3121 Tests grün (Stand 2307027).
**Einordnung der Prüfregeln (für Task 4 und 5):** `check()` meldet je Schlüssel genau eine deutsche Meldung mit dem Label als Präfix (`„Fließtext-Schriftgröße: …“`), Task 4 setzt davor den Feldpfad. `null` ist „zurücksetzen“ und wird vom Aufrufer vor `check()` behandelt; `check(…, null)` ist trotzdem definiert und lehnt ab. Schriftnamen: nur Form (1–100 Zeichen, keine Steuerzeichen, kein `<>"'` und Backtick, nicht `none`); ob die Schrift existiert, prüft `FontCatalog` (Task 4) mit `FontSuggest`. Zahlen kommen als Zahl oder als Ziffern-String (`"15"`, `"1.7"`, `"-1"`), Exponent, Einheit und Leerzeichen sind keine Zahl.
#### Task 3a: `ThemeOptionSpec`
Die Tabelle steht als Literal in der Klasse (`DEFINITIONS`), die geteilten Bereiche als Konstanten (`BODY_SIZE`, `HEADER_SIZE`, `LINE_HEIGHT`, `WEIGHT`, `FONT`), damit keine Zeile über 120 Zeichen läuft. Der Mirror `customizer-typography` (Task 2) hasht Divis Funktion; wer die Tabelle ändert, ändert sie nur nach einem Divi-Update und mit neuem Fingerabdruck.

### Task 4: `ThemeOptionsArea`, `lit/divi-theme-options-get`, `lit/divi-theme-options-update` (W2–W7, W14)
**Files:**
- Create: `src/Integrations/Divi/Design/ThemeOptionsArea.php`, `DiviThemeOptionsGetAbility.php`, `FontCheck.php`, `DiviThemeOptionsUpdateAbility.php`
- Test (neu): `tests/Unit/Integrations/Divi/Design/ThemeOptionsAreaTest.php`, `DiviThemeOptionsGetAbilityTest.php`, `FontCheckTest.php`, `DiviThemeOptionsUpdateAbilityTest.php` (alle über `LIT\MCP\Tests\Unit\TestCase`, weil sie Mockery-Fakes der Adapter nutzen)
- Keine Verdrahtung in `DiviIntegration` (Task 9).
**Interfaces:**
- Consumes (Schnittstellenvertrag, Tasks 1–3): `DiviFeature::ThemeOptionRead`/`ThemeOptionWrite`; `ThemeOptionsAdapter::read()`, `::sanitize(string, mixed): mixed`, `::write(array $set, list<string> $unset): array` (liefert das Zurückgelesene), `::canCustomize()`; `FontCatalog::names()`, `::has()`; `DesignRights::themeOptions(DesignSystemWriter, ThemeOptionsAdapter): ?WP_Error`; `ThemeOptionSpec::KEYS`, `::definition()`, `::isKey()`, `::check()`, `::normalize()`, `::effective()`; `ThemeOptionBook::fromDivi()`, `data()`, `rev()`, `has()`, `get()`, `with()`, `without()`; `ThemeOptionDiff::between()`, `::summary()`; `FontSuggest::similar()`. Bestehend: `DesignArea`, `DesignChange::run()/inputProperties()/outputSchema()`, `DesignPlan`, `ItemKeys::refuseUnknown()`, `Errors`, `Annotations`.
- Produces:
- `final class ThemeOptionsArea implements DesignArea` – `__construct(ThemeOptionsAdapter $options)`, Name `theme_options`, Label `Theme-Optionen`, Fähigkeit `ThemeOptionWrite`; zusätzlich `public const SITE_WIDE` (W7-Warnung, auch für Task 6) und `public static function same(mixed $a, mixed $b): bool` (gleich oder dieselbe Zahl in anderem Typ; auch vom Update genutzt).
- `final class DiviThemeOptionsGetAbility implements Ability, RequiresDiviFeatures` – **`__construct(ThemeOptionsAdapter $options)`** (ohne `FontCatalog`, siehe ABWEICHUNGEN), `lit/divi-theme-options-get`, Fähigkeiten `[ThemeOptionRead]`.
- `final class FontCheck` – `public static function problem(FontCatalog $fonts, string $name): ?string` (null = Divi kennt die Schrift exakt; sonst deutsche Meldung mit bis zu fünf Vorschlägen oder dem Hinweis auf `lit/divi-fonts-upload`). Auch von Task 5 genutzt.
- `final class DiviThemeOptionsUpdateAbility implements Ability, RequiresDiviFeatures` – `__construct(DesignSystemWriter $writer, ThemeOptionsAdapter $options, FontCatalog $fonts, DesignChange $change)` (wie Vertrag), `lit/divi-theme-options-update`, Fähigkeiten `[ThemeOptionRead, ThemeOptionWrite]`.
- Testhilfen für spätere Tests: `ThemeOptionsAreaTest::stored()` (`body_font` „Open Sans“, `body_font_size` 16, `body_font_height` 1.8), `ThemeOptionsAreaTest::adapter(array &$stored, array &$writes, ?Closure $sanitize = null, bool $customize = true)` (zustandsbehafteter Fake: `write()` setzt/löscht wie `et_update_option`/`et_delete_option` und liefert das Zurückgelesene), `FontCheckTest::catalog()` (`FontCatalog`-Fake über `Lato, Open Sans, Roboto, Roboto Mono, Roboto Slab`, `has()` exakt).
**Regeln dieses Tasks (alle durch Tests belegt):**
- `ThemeOptionsArea::write()` ersetzt immer die ganze Whitelist: Schlüssel des Bestands → `$set`, Whitelist-Schlüssel, die fehlen → `$unset` (W6); `$mayRemove` ist bedeutungslos, weil ein fehlender Schlüssel „zurück auf Divi-Standard“ heißt (W3). `restore()` = `write($raw, true)`. Ergebnis ist das, was `ThemeOptionsAdapter::write()` zurückliest (kein zweiter Lesezugriff).
- `verify()` verlangt dieselben Schlüssel und dieselben Werte; toleriert wird nur eine Zahl in anderem Typ (`15`, `"15"`, `15.0`) – die Werte des Plans sind schon die Ausgabe von Divis Sanitizer, also ist jede andere Abweichung ein Fehler (→ Rollback). `false` ≠ `''`, Schriftnamen exakt. `differences()` nennt die tolerierten Typwechsel als Warnung („Divi hat die Theme-Option „Textgröße“ als „16“ statt 16 gespeichert.“).
- `theme-options-get` liefert je Schlüssel (alle oder `keys`, immer in der Reihenfolge von `ThemeOptionSpec::KEYS`) `key, label, type, value` (gespeicherter Rohwert, `null` = nicht gesetzt), `effective` (`ThemeOptionSpec::effective` auf dem Bestand), `default` (`effective` auf dem Bestand ohne diesen Schlüssel – bei Tablet/Smartphone also die geerbte Größe, W3), `is_default` (nicht gespeichert) und die Felder `min, max, step, choices, inherits` der Definition, soweit vorhanden; dazu `design_rev` (`ThemeOptionBook::rev()`, dieselbe wie die des Probelaufs) und `notes` (Update-Tool, `null`, Vererbung, Hauptfarben → `lit/divi-colors-set`). Die fünf Hauptfarben selbst liest das Tool nicht (kein Leser im Vertrag; der Hinweis genügt). Recht: `edit_posts` in `permission()` **und** `execute()`, vor jedem Lesen.
- `theme-options-update`: Eingabe `{set: {<key>: Wert|null, …}, confirm?, design_rev?}`. `set` muss ein nicht leeres Objekt sein. Gesammelt mit Pfad `set.<key>`: unbekannte Schlüssel (`ItemKeys`, „unbekanntes Feld“; bei `delete` mit Hinweis auf `null`), `false` und `'none'` (Hinweis auf `null`, W3), `ThemeOptionSpec::check()`, bei den vier Schriftschlüsseln `FontCheck` (vor Divis Sanitizer, der nur `false` liefern würde), dann `ThemeOptionsAdapter::sanitize()` auf den normalisierten Wert: kein Skalar/`false` → „Divi lehnt den Wert ab“, abweichend (außer Zahl in anderem Typ) → „Divi würde den Wert verändert speichern (…)“. Gespeichert wird die Ausgabe des Sanitizers (Typ von Divi, W4). `null` → `without()` (Divi: `et_delete_option`).
- Ein nicht gesetzter Tablet-/Smartphone-Schlüssel, dessen neuer Wert der geerbten Größe gleicht, bleibt ungesetzt (kein Diff); weil die Schlüssel in der Reihenfolge von `KEYS` (Desktop vor Tablet vor Smartphone) angewendet werden, zählt dabei die Desktop-Größe desselben Aufrufs.
- Plan: `ThemeOptionDiff::between/summary`, `usages = null` (kein `affected`-Inhalt, DesignChange setzt `affected: []`), `mayRemove = false`; Warnungen nur bei Änderungen: immer `ThemeOptionsArea::SITE_WIDE`, bei einer Schrift zusätzlich der Builder-Hinweis (W7).
- Fähigkeiten des Updates `[ThemeOptionRead, ThemeOptionWrite]`: das Tool liest `et_divi` und die Customizer-Tabelle (ThemeOptionRead), ruft Sanitizer, Schriftliste und Schreiben (ThemeOptionWrite, W1). `DesignRead` braucht es nicht – es liest weder Presets noch das Designsystem (anders als `lit/divi-colors-set`, dessen Warnungen Presets lesen).

- [ ] **Step 4a.1: Failing Test `ThemeOptionsAreaTest` schreiben**

#### Task 4 – Abschluss
- [ ] **Step 4.8: Gesamtlauf**
Run: `composer test && composer lint`
Expected: alle Unit-Tests grün – Stand nach Task 3 + 31 neue Tests (Probelauf des Planers mit Platzhaltern für Tasks 1–3: 3121 → 3152), Lint ohne Meldung. Schlägt `DiviBoundaryTest` oder `CoreIndependenceTest` an, steht in den neuen Klassen ein Divi-/WordPress-Aufruf, der in den Adapter gehört – entfernen, nicht den Test anpassen. Die neuen Tools sind noch nicht registriert (Task 9); `DiviToolFeaturesTest` ändert sich deshalb hier nicht.
---
### Task 5: Schriftprüfung der Schrift-Variablen in `lit/divi-variables-set` (W5, W12)
**Files:**
- Modify: `src/Integrations/Divi/Design/DiviVariablesSetAbility.php` (Konstruktor, `value()`, Docblock), `src/Integrations/Divi/Design/VariableValue.php` (nur Docblock, Zeile 10–12), `src/Integrations/Divi/DiviIntegration.php` (nur das Konstruktor-Argument, damit die Suite grün bleibt)
- Test: `tests/Unit/Integrations/Divi/Design/DiviVariablesSetAbilityTest.php` (Hilfe `ability()` + vier neue Tests)
**Interfaces:**
- Consumes: `FontCatalog` (Task 2), `FontCheck::problem()` (Task 4c), `FontCheckTest::catalog()` (Task 4c).
- Produces: **neue Konstruktor-Signatur** `DiviVariablesSetAbility::__construct(DesignSystemWriter $writer, GlobalVariablesAdapter $variables, DesignChange $change, GlobalUsages $usages, FontCatalog $fonts, ?Closure $random = null)` – `FontCatalog` steht vor dem optionalen `$random` (nur Tests übergeben es). Task 9 ersetzt das hier eingesetzte `new FontCatalog()` durch die gemeinsame Instanz der Integration (eine Schriftliste je Request für Variablen, Theme-Optionen und Upload).
- `diviFeatures()` bleibt `[DesignRead, VariableWrite]`: die Schriftlisten-Aufrufe tragen laut W1 auch `variable-write`; ein Bruch der Liste sperrt das Tool bewusst.
**Regeln:** Nur Variablen vom Typ `fonts` und nur, wenn `VariableValue::check()` den Wert schon angenommen hat, gehen an `FontCheck` (exakter Name aus `FontCatalog`, sonst Fehler `items[i].value` mit Vorschlägen). Andere Typen und ein formal ungültiger Schriftname laden die Liste nicht (sie kostet 1,3 MB, W5). `VariableValue` bleibt rein.
- [ ] **Step 5.1: Tests anpassen und ergänzen**
In `tests/Unit/Integrations/Divi/Design/DiviVariablesSetAbilityTest.php`:
1. Import ergänzen (nach `use LIT\MCP\Integrations\Divi\Design\DiviVariablesSetAbility;`):
```php
use LIT\MCP\Integrations\Divi\Design\FontCatalog;
```
2. In `ability()` den Parameter `bool $manage = true` ersetzen durch
```php
bool $manage = true,
?FontCatalog $fonts = null
```
und im Konstruktoraufruf nach `$usages ?? self::usages(self::unused()),` einfügen:
```php
$fonts ?? FontCheckTest::catalog(),
```
3. Am Ende der Klasse (vor der letzten `}`) anfügen:
```php
/** Ruling W12: a font variable names a font Divi knows exactly; unknown names get suggestions. */
public function testFontVariablesNeedAFontDiviKnows(): void
{
$error = $this->ability()
->execute(['items' => [['type' => 'fonts', 'label' => 'Marke', 'value' => 'robotto']]]);
self::assertToolError($error, 'validation_failed');
$fields = self::errorFields($error);
self::assertSame(['items[0].value'], array_keys($fields));
self::assertStringStartsWith('unbekannte Schrift „robotto“; ähnlich: ', $fields['items[0].value']);
self::assertStringContainsString('Roboto', $fields['items[0].value']);
self::assertSame([], $this->saves);
}
public function testAFontVariableWithAKnownFontIsPlanned(): void
{
$dry = self::assertToolError(
$this->ability()->execute(['items' => [['type' => 'fonts', 'label' => 'Marke', 'value' => 'Roboto Slab']]]),
'confirm_required'
);
self::assertSame(['added'], array_column($dry['diff'], 'action'));
}
/** The font list is loaded only for font variables (it costs 1.3 MB, ruling W5). */
public function testOtherTypesDoNotLoadTheFontList(): void
{
$fonts = Mockery::mock(FontCatalog::class);
$fonts->shouldNotReceive('has', 'names');
self::assertToolError(
$this->ability(fonts: $fonts)->execute(['items' => [
['type' => 'strings', 'label' => 'Gruß', 'value' => 'Hallo'],
['id' => 'Eckenradius', 'value' => '12px'],
]]),
'confirm_required'
);
}
/** VariableValue checks first: a malformed name never reaches the font list. */
public function testAMalformedFontNameFailsBeforeTheFontList(): void
{
$fonts = Mockery::mock(FontCatalog::class);
$fonts->shouldNotReceive('has', 'names');
$error = $this->ability(fonts: $fonts)
->execute(['items' => [['type' => 'fonts', 'label' => 'Marke', 'value' => 'Roboto; x']]]);
self::assertToolError($error, 'validation_failed');
self::assertStringStartsWith('Schrift:', self::errorFields($error)['items[0].value']);
}
```
- [ ] **Step 5.2: RED-Lauf**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter DiviVariablesSetAbilityTest`
Expected: `Tests: 21, Assertions: 17, Errors: 21.` mit `TypeError: …DiviVariablesSetAbility::__construct(): Argument #5 ($random) must be of type ?Closure, Mockery_…_FontCatalog given`.
- [ ] **Step 5.3: `DiviVariablesSetAbility` erweitern**
In `src/Integrations/Divi/Design/DiviVariablesSetAbility.php`:
1. Docblock der Klasse – den Satz zur Wertprüfung ersetzen:
```php
* builder. Values are checked per type (VariableValue); an active variable needs one. The dry run lists the posts that
* reference a changed, archived or activated variable (ReferenceUsageQuery) and warns about presets that use it.
*/
```
durch
```php
* builder. Values are checked per type (VariableValue), font variables also against Divi's font list (FontCheck, ruling
* W12); an active variable needs one. The dry run lists the posts that reference a changed, archived or activated
* variable (ReferenceUsageQuery) and warns about presets that use it.
*/
```
2. Konstruktor: nach `private GlobalUsages $usages,` einfügen
```php
private FontCatalog $fonts,
```
3. In `apply()` die Zeile `'value' => self::value($type, $item['value']),` ersetzen durch
```php
'value' => $this->value($type, $item['value']),
```
4. `value()` wird eine Instanzmethode mit der Listenprüfung – den Anfang der Methode ersetzen:
```php
/** @throws InvalidArgumentException */
private function value(string $type, mixed $value): string
{
if (is_int($value)) {
$value = (string) $value; // an attachment ID for images
}
if (! is_string($value)) {
throw new InvalidArgumentException('Wert als Text erwartet');
}
$problem = VariableValue::check($type, $value);
if ($problem === null && $type === 'fonts') {
$problem = FontCheck::problem($this->fonts, $value);
}
```
(der Rest – `if ($problem !== null) { throw … }` und `return $value;` – bleibt).
5. `src/Integrations/Divi/Design/VariableValue.php`, Docblock der Klasse:
```php
* (new in Divi 5.15) is passed through by VariableBook, but the tools never create or change it. The check of fonts
* against Divi's font list follows with 4d. Pure PHP.
```
ersetzen durch
```php
* (new in Divi 5.15) is passed through by VariableBook, but the tools never create or change it. Font names are only
* checked for their form here; DiviVariablesSetAbility checks them against Divi's font list (FontCheck, ruling W12).
* Pure PHP.
```
6. `src/Integrations/Divi/DiviIntegration.php` (minimal, damit `DiviIntegrationTest` grün bleibt; die gemeinsame Instanz folgt mit Task 9): Import `use LIT\MCP\Integrations\Divi\Design\FontCatalog;` (alphabetisch nach `DiviVariablesSetAbility`) und im Aufruf
```php
new DiviVariablesSetAbility(
$this->designWriter,
$this->variablesAdapter,
$this->designChange(),
$this->globalUsages(),
new FontCatalog()
),
```
- [ ] **Step 5.4: GREEN-Lauf**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter 'DiviVariablesSetAbilityTest|DiviIntegrationTest'`
Expected: `OK (36 tests, 344 assertions)` (21 + 15).
- [ ] **Step 5.5: Gesamtlauf, Lint, Commit**
Run: `composer test && composer lint`
Expected: grün, Stand nach Task 4 + 4 Tests (Probe: 3156), Lint ohne Meldung.
```bash

### Task 6: `ThemeOptionsRestorePlanner` – Restore für `theme_options` (W6, W11)
**Files:**
- Create: `src/Integrations/Divi/Design/ThemeOptionsRestorePlanner.php`
- Modify: `src/Integrations/Divi/Design/DiviDesignRestoreAbility.php` (Docblock, Beschreibung, Text des `unsupported`-Zweigs)
- Test: `tests/Unit/Integrations/Divi/Design/ThemeOptionsRestorePlannerTest.php` (neu), `DiviDesignRestoreAbilityTest.php` (angepasst)
**Interfaces:**
- Consumes: `ThemeOptionsArea`, `ThemeOptionsArea::SITE_WIDE` (Task 4a), `ThemeOptionsAreaTest::adapter()`, `DesignRights::themeOptions()`, `ThemeOptionBook`, `ThemeOptionDiff`, `ThemeOptionSpec::definition()` (Tasks 2/3).
- Produces: `final class ThemeOptionsRestorePlanner implements RestorePlanner` – **`__construct(DesignSystemWriter $writer, ThemeOptionsAdapter $options)`**; `area()` = `theme_options`, `designArea()` = `new ThemeOptionsArea($options)`, `rights()` = `DesignRights::themeOptions($writer, $options)`, `features()` = `[ThemeOptionRead, ThemeOptionWrite]` (wie das Update-Tool). Testhilfen `ThemeOptionsRestorePlannerTest::SNAPSHOT_ID`, `::current()`, `::snapshot()`.
- `DiviDesignRestoreAbility::__construct(DesignChange, SnapshotStore, RestorePlanner ...$planners)` bleibt; Task 9 hängt in `DiviIntegration::abilities()` an die Planerliste `new ThemeOptionsRestorePlanner($this->designWriter, <ThemeOptionsAdapter der Integration>)` an (wie 4c Task 9 die Farb-/Variablen-Planer). Ohne diese Zeile bleibt `theme_options` `unsupported` – die Suite braucht sie nicht.
**Regeln:** Der Snapshot ersetzt die ganze Whitelist (`mayRemove = true`); fehlt ein Schlüssel im Snapshot, ist das eine `reset`-Zeile und eine Warnung, die die Labels nennt. Zusammenfassung `Snapshot <id> wiederherstellen – <ThemeOptionDiff::summary>`. Bei Änderungen zusätzlich `SITE_WIDE`; ohne Änderung keine Warnung. Der `unsupported`-Zweig der Restore-Ability bleibt für Bereiche ohne Planer, ohne den Verweis auf Etappe 4d.

```
#### Task 6b: `lit/divi-design-restore` kennt `theme_options`
- [ ] **Step 6b.1: `DiviDesignRestoreAbilityTest` anpassen**
In `tests/Unit/Integrations/Divi/Design/DiviDesignRestoreAbilityTest.php`:
1. Importe ergänzen (nach `use LIT\MCP\Integrations\Divi\Design\SnapshotStore;`):
```php
use LIT\MCP\Integrations\Divi\Design\ThemeOptionBook;
use LIT\MCP\Integrations\Divi\Design\ThemeOptionsAdapter;
use LIT\MCP\Integrations\Divi\Design\ThemeOptionsRestorePlanner;
```
2. `testUnknownSnapshotAndThemeOptions()` ersetzen durch die zwei Tests:
```php
public function testUnknownSnapshots(): void
{
$snapshots = Mockery::mock(SnapshotStore::class);
$snapshots->allows('get')->andReturn(null);
$ability = self::allAreas($snapshots, self::colorStore([]), self::variableStore([]));
self::assertToolError($ability->execute(['snapshot_id' => 'presets-20261016T100000Z-abcdef']), 'not_found');
self::assertToolError($ability->execute(['snapshot_id' => 'colors-20261016T100000Z-abcdef']), 'not_found');
self::assertToolError($ability->execute(['snapshot_id' => 'variables-20261016T100000Z-abcdef']), 'not_found');
self::assertToolError(
$ability->execute(['snapshot_id' => 'theme_options-20261016T100000Z-abcdef']),
'not_found'
);
self::assertToolError($ability->execute(['snapshot_id' => 'kaputt']), 'validation_failed');
}
/** A snapshot area whose planner is not wired stays unsupported (W11) – never a silent no-op. */
public function testAnAreaWithoutAPlannerIsUnsupported(): void
{
Functions\when('current_user_can')->justReturn(true);
$writer = Mockery::mock(DesignSystemWriter::class);
$writer->allows('canUseVisualBuilder')->andReturn(true);
$snapshots = Mockery::mock(SnapshotStore::class);
$snapshots->shouldNotReceive('get');
$ability = new DiviDesignRestoreAbility(
new DesignChange($snapshots, FakeChangeLog::forbidden()),
$snapshots,
new PresetRestorePlanner($writer)
);
$error = self::assertToolError(
$ability->execute(['snapshot_id' => ThemeOptionsRestorePlannerTest::SNAPSHOT_ID]),
'unsupported'
);
self::assertStringNotContainsString('4d', $error['hint']);
}
```
3. `allAreas()` bekommt den Theme-Options-Planer – die ganze Methode samt neuer Hilfe `optionStore()` ersetzen:
```php
/** The ability with the planners of all four areas; the user has every right unless a store says otherwise. */
private static function allAreas(
SnapshotStore $snapshots,
GlobalColorsAdapter $colors,
GlobalVariablesAdapter $variables,
?FakeChangeLog $log = null,
?ThemeOptionsAdapter $options = null
): DiviDesignRestoreAbility {
Functions\when('current_user_can')->justReturn(true);
$writer = Mockery::mock(DesignSystemWriter::class);
$writer->allows('canUseVisualBuilder')->andReturn(true);
$writer->allows('presets')->andReturn(PresetBookTest::stored());
$writer->shouldNotReceive('savePresets');
$noOptions = [];
return new DiviDesignRestoreAbility(
new DesignChange($snapshots, $log ?? FakeChangeLog::forbidden()),
$snapshots,
new PresetRestorePlanner($writer),
new ColorRestorePlanner($writer, $colors),
new VariableRestorePlanner($writer, $variables),
new ThemeOptionsRestorePlanner($writer, $options ?? self::optionStore($noOptions))
);
}
/**
* A theme options adapter that reads what it last wrote, starting with $stored (ThemeOptionsAreaTest::adapter()).
*
* @param array<string, int|float|string|false> $stored
*/
private static function optionStore(array &$stored, bool $customize = true): ThemeOptionsAdapter
{
$writes = [];
return ThemeOptionsAreaTest::adapter($stored, $writes, null, $customize);
}
```
(Der Docblock nennt jetzt „all four areas“.)
4. Vor `testRightsFollowTheSnapshotArea()` den Restore-Test einfügen und den Rechte-Test ersetzen:
```php
public function testRestoresThemeOptionsAndResetsTheKeysTheSnapshotLacks(): void
{
$id = ThemeOptionsRestorePlannerTest::SNAPSHOT_ID;
$stored = ThemeOptionsRestorePlannerTest::current();
$snapshots = Mockery::mock(SnapshotStore::class);
$snapshots->allows('get')->with('theme_options', $id)
->andReturn(self::snapshotIn('theme_options', $id, ThemeOptionsRestorePlannerTest::snapshot()));
$snapshots->expects('save')
->with(
'theme_options',
ThemeOptionBook::fromDivi(ThemeOptionsRestorePlannerTest::current())->data(),
'lit/divi-design-restore'
)
->andReturn('theme_options-5');
$snapshots->expects('attachLog');
$ability = self::allAreas(
$snapshots,
self::colorStore([]),
self::variableStore([]),
new FakeChangeLog(8),
self::optionStore($stored)
);
$dry = self::assertToolError($ability->execute(['snapshot_id' => $id]), 'confirm_required');
self::assertSame(['added', 'changed', 'reset'], array_column($dry['diff'], 'action'));
self::assertStringContainsString('Divi-Standard', $dry['warnings'][1]);
$result = $ability->execute(['snapshot_id' => $id, 'confirm' => true, 'design_rev' => $dry['design_rev']]);
self::assertSame('theme_options-5', $result['snapshot_id']);
self::assertSame(
ThemeOptionBook::fromDivi(ThemeOptionsRestorePlannerTest::snapshot())->data(),
ThemeOptionBook::fromDivi($stored)->data()
);
}
/** Spec §10, V10: the rights are those of the snapshot's area. */
public function testRightsFollowTheSnapshotArea(): void
{
$snapshots = Mockery::mock(SnapshotStore::class);
$snapshots->shouldNotReceive('get');
$options = [];
$ability = self::allAreas(
$snapshots,
self::colorStore([]),
self::variableStore([], false),
null,
self::optionStore($options, false)
);
self::assertToolError(
$ability->permission(['snapshot_id' => VariableRestorePlannerTest::SNAPSHOT_ID]),
'forbidden'
);
self::assertToolError(
$ability->execute(['snapshot_id' => VariableRestorePlannerTest::SNAPSHOT_ID]),
'forbidden'
);
self::assertToolError(
$ability->permission(['snapshot_id' => ThemeOptionsRestorePlannerTest::SNAPSHOT_ID]),
'forbidden'
);
self::assertTrue($ability->permission(['snapshot_id' => ColorRestorePlannerTest::SNAPSHOT_ID]));
self::assertTrue($ability->permission(['snapshot_id' => 'presets-20261016T100000Z-aaaaaa']));
self::assertToolError($ability->permission(['snapshot_id' => 'kaputt']), 'forbidden', 'fail closed');
}
```
5. `testFeaturesFollowTheSnapshotArea()` ersetzen:
```php
public function testFeaturesFollowTheSnapshotArea(): void
{
$ability = self::allAreas(Mockery::mock(SnapshotStore::class), self::colorStore([]), self::variableStore([]));
self::assertSame(
[DiviFeature::DesignRead, DiviFeature::ColorWrite],
$ability->diviFeatures(['snapshot_id' => ColorRestorePlannerTest::SNAPSHOT_ID])
);
self::assertSame(
[DiviFeature::DesignRead, DiviFeature::VariableWrite],
$ability->diviFeatures(['snapshot_id' => VariableRestorePlannerTest::SNAPSHOT_ID])
);
self::assertSame(
[DiviFeature::DesignRead, DiviFeature::PresetWrite],
$ability->diviFeatures(['snapshot_id' => 'presets-20261016T100000Z-aaaaaa'])
);
self::assertSame(
[DiviFeature::ThemeOptionRead, DiviFeature::ThemeOptionWrite],
$ability->diviFeatures(['snapshot_id' => ThemeOptionsRestorePlannerTest::SNAPSHOT_ID])
);
self::assertSame(
[DiviFeature::DesignRead, DiviFeature::PresetWrite, DiviFeature::ColorWrite, DiviFeature::VariableWrite,
DiviFeature::ThemeOptionRead, DiviFeature::ThemeOptionWrite],
$ability->diviFeatures([])
);
}
```
- [ ] **Step 6b.2: RED-Lauf**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter DiviDesignRestoreAbilityTest`
Expected: `Tests: 10, Assertions: 116, Failures: 1.` – nur `testAnAreaWithoutAPlannerIsUnsupported` mit `Failed asserting that 'Theme-Optionen folgen mit Etappe 4d.' does not contain "4d".` Der Restore über den neuen Planer ist schon grün: die Ability ist planer-generisch (4c), sie braucht nur die neuen Texte.
- [ ] **Step 6b.3: `DiviDesignRestoreAbility` anpassen**
In `src/Integrations/Divi/Design/DiviDesignRestoreAbility.php`:
1. Docblock der Klasse, letzter Satz:
```php
* the plan. Areas without a planner (theme_options until Etappe 4d) are not restorable yet.
```
ersetzen durch
```php
* the plan. A snapshot of an area without a planner is refused as unsupported, never treated as a no-op.
```
2. In `description()` das Ende ab `Bereiche:` ersetzen:
```php
. 'beim Nutzer confirm: true; vorher wird der aktuelle Stand selbst gesichert. Bereiche: presets, colors '
. '(Farben, die es im Snapshot nicht gibt, entfallen), variables (Variablen, die erst nach dem Snapshot '
. 'entstanden, bleiben archiviert erhalten) und theme_options (Theme-Optionen, die im Snapshot nicht '
. 'gesetzt sind, kehren zum Divi-Standard zurück).';
```
3. Der `unsupported`-Zweig in `execute()`:
```php
return Errors::unsupported(
'Snapshots dieses Bereichs lassen sich hier nicht wiederherstellen.',
'Den Stand des Snapshots im Divi-Builder bzw. -Customizer von Hand herstellen.'
);
```
- [ ] **Step 6b.4: GREEN-Lauf**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter 'DiviDesignRestoreAbilityTest|ThemeOptionsRestorePlannerTest'`
Expected: `OK (14 tests, 137 assertions)`.
- [ ] **Step 6b.5: Gesamtlauf, Lint, Commit**
Run: `composer test && composer lint`
Expected: grün, Stand nach Task 5 + 6 Tests (Probe: 3162), Lint ohne Meldung.
```bash
git add src/Integrations/Divi/Design/DiviDesignRestoreAbility.php \
tests/Unit/Integrations/Divi/Design/DiviDesignRestoreAbilityTest.php
git commit -m "feat: lit/divi-design-restore stellt theme_options wieder her; Hinweis auf Etappe 4d entfällt" \
-m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"
```
### Task 7: `RemoteFileFetcher` aus `MediaImporter` herauslösen (Refactor, Verhalten gleich)
Der URL-Teil von `MediaImporter` (Schema-, Core- und eigene Bereichsprüfung, IPv4-Pin, Weiterleitungs-Hook, Streamen in eine Temp-Datei mit Abschneiden bei Limit + 1 Byte, Zeitlimit 30 s, Protokoll ohne Zugangsdaten/Query, keine Fehlerursache für den Client – Security-Audit M3) wandert unverändert in die neue Klasse `RemoteFileFetcher`, damit `lit/divi-fonts-upload` (Task 8) dieselbe Härtung nutzt. Medienbezogen bleiben in `MediaImporter`: die Fehlermeldungen an den Client (`validation_failed` mit `url`), die `Content-Length`-Prüfung gegen `Limits::uploadBytes()`, Typprüfung, Sideload, Alt-Text. Der Konstruktor `MediaImporter(Limits, ?Closure $resolve)` bleibt gleich – `MediaIntegration` und alle Tests bleiben unverändert. Sicherheitsnetz: `MediaImporterTest` (deckt die Wächter über `fromUrl()` ab), `MediaUploadAbilitiesTest`, `PublicAddressTest` – sie werden **nicht** geändert. `RemoteFileFetcherTest` prüft nur, was ein zweiter Aufrufer braucht (Limit als Parameter, `null` statt Fehlermeldung, Protokoll-Kontext, Hooks nur während des Requests).
**Files:**
- Create: `src/Integrations/Media/RemoteFileFetcher.php`
- Modify: `src/Integrations/Media/MediaImporter.php`
- Test: `tests/Unit/Integrations/Media/RemoteFileFetcherTest.php` (neu); `MediaImporterTest.php`, `MediaUploadAbilitiesTest.php`, `PublicAddressTest.php` unverändert
**Interfaces:**
- Consumes: `PublicAddress::hostIsPublic()`/`dnsResolver()`, `Log::failure()`, WordPress `wp_parse_url`, `wp_http_validate_url`, `wp_safe_remote_get`, `wp_remote_retrieve_response_code`, `add_action`/`remove_action` (Hooks `http_api_curl`, `requests-requests.before_redirect`).
- Produces (Task 8 nutzt, Task 9 verdrahtet mit `new RemoteFileFetcher()`):
```php
// src/Integrations/Media/RemoteFileFetcher.php – class (nicht final, für Fakes)
public function __construct(?Closure $resolve = null); // DNS-Lookup; null = PublicAddress::dnsResolver()
public function allows(string $url): bool; // http(s) + wp_http_validate_url + nur öffentliche Adressen
/** @return array<string, mixed>|null Antwort (Header, Status); null = Download fehlgeschlagen (Grund nur im Log) */
public function fetch(string $url, string $tmp, int $maxBytes, string $context): ?array; // limit_response_size = $maxBytes + 1
```
- Unverändert: `MediaImporter::__construct(Limits $limits, ?Closure $resolve = null)`, `fromUrl()`, `fromBase64()`. Keine Verdrahtungsänderung nötig.
- [ ] **Step 1: Sicherheitsnetz grün**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter 'MediaImporterTest|MediaUploadAbilitiesTest|PublicAddressTest'`
Expected: `OK (71 tests, 246 assertions)`
- [ ] **Step 2: Failing Test für `RemoteFileFetcher` schreiben**

### Task 8: `FontSignature`, `FontNameRules`, `FontInstaller`, `lit/divi-fonts-upload`
Schriften hochladen nach W8–W10, in drei Blöcken mit je eigenem Commit: 8a reine Regeln (Magic Bytes, Namen), 8b Divi-Adapter `FontInstaller` mit Manifest, Mirror `font-install` und Fingerabdrücken, 8c die Ability. Ablauf der Ability: Rechte (`DesignRights::fonts()`) in `permission()` und `execute()` → alle Eingabefehler gesammelt (`validation_failed` mit Feldpfaden, auch unbekannte Schlüssel oben und unter `files`) → Name belegt: `conflict` → Download jeder Datei über `RemoteFileFetcher` (je höchstens `min(Limits::uploadBytes(), 5 MB)`), Größe, `FontSignature` passend zum Schlüssel, `FontInstaller::accepts()` → ohne `confirm` `confirm_required` mit Name, Dateien (`format`, `bytes`, `sha256`), Gewichten, Familie und Hinweis „ganze Website“; mit `confirm: true` erneuter Download + Prüfung, `FontInstaller::install()`, Teilerfolg → `FontInstaller::remove()` (`WriteFailed::rolledBack`, sonst `partial` + `recordPartial`), Erfolg → `ChangeLog::record('lit/divi-fonts-upload', 'divi_font', <Name>, …SHA-256…)`. Temp-Dateien werden auf jedem Weg gelöscht (`try/finally`). Neue Fehlercodes (Spec §11): `font_fetch_failed` (400, mindestens eine Datei nicht abrufbar – ohne Ursache, M3) und `font_invalid` (400, Größe/Inhalt/Divi-Prüfung), beide mit `fields`; `conflict` (409) wie in `DesignChange`.
**Voraussetzung aus Task 1–2 (Schnittstellenvertrag):** `DiviFeature::FontUpload` (`font-upload`, schreibend), `FontCatalog::reserved()`/`canManage()`, `DesignRights::fonts(FontCatalog): ?WP_Error`. Die Tests ersetzen `FontCatalog` per Mockery und hängen nur an `reserved()`/`canManage()`; die Rechte-Tests verlangen nur `forbidden` (Texte gehören Task 2).
**Files:**
- Create: `src/Integrations/Divi/Design/FontSignature.php`, `FontNameRules.php`, `FontInstaller.php`, `DiviFontsUploadAbility.php`; `tests/Fixtures/divi/reference/font-install.txt` (generiert)
- Modify: `src/Integrations/Divi/Release/DiviAdapters.php`, `src/Integrations/Divi/Release/fingerprints.json` (generiert)
- Test: `tests/Unit/Integrations/Divi/Design/FontSignatureTest.php`, `FontNameRulesTest.php`, `FontInstallerTest.php`, `DiviFontsUploadAbilityTest.php` (neu); `tests/Unit/Integrations/Divi/Release/DiviFeatureAssignmentTest.php`, `tests/Unit/Integrations/Divi/Cli/DiviCheckCommandTest.php` (geändert)
**Interfaces:**
- Consumes: `DiviFeature::FontUpload`, `FontCatalog` (`reserved()`, `canManage()`), `DesignRights::fonts()` (Task 1–2); `RemoteFileFetcher` (Task 7); `Limits::uploadBytes()`, `ChangeLog::record()`/`recordPartial()`, `Rollback::attempt()`, `WriteFailed::rolledBack()`/`partial()`, `Errors::make()`/`invalidInput()`/`confirmRequired()`/`writeFailed()`, `ToolResult`, `Annotations::write(false)`, `AdminIncludes::load()` (lädt `wp-admin/includes/file.php` für `wp_tempnam` und `wp_handle_upload`), `ReleaseGate::assertFeature()`.
- Divi (nur `FontInstaller`): `FontsUtility::mime_types_font` (0), `HooksRegistration::check_filetype_and_ext_font` (3), `FontsUtility::font_add` (4), `FontsUtility::font_remove` (1), Konstante `FontsUtility::FONT_NAME_MAX_LENGTH`, Mirror `font-install` (`AiAgentImageUtility::install_to_custom_fonts`); alle mit `font-upload`. WordPress (kein Manifest): `sanitize_file_name`, `is_wp_error`, `wp_tempnam`, `wp_delete_file`, `wp_handle_upload` (in `font_add`).
- Produces (Task 9 verdrahtet):
```php
// FontSignature.php – reines PHP
public const HEADER_BYTES = 4;
public static function detect(string $header): ?string; // 'woff2'|'woff'|'ttf'|'otf'|null
// FontNameRules.php – reines PHP
public const MAX_LENGTH = 100;
public static function check(string $name, array $reserved, int $maxLength = self::MAX_LENGTH): ?string;

public const FORMATS = ['woff2', 'woff', 'ttf', 'otf'];
public function __construct(); // keine Abhängigkeiten
public function formats(): array; public function nameMaxLength(): int;
public function accepts(string $path, string $filename): bool;
public function install(string $name, array $files, string $weights, string $family): array; // gespeicherte Endungen; @throws DiviLocked, RuntimeException (dann ist nichts gespeichert)
public function remove(string $name): void; // @throws RuntimeException
// DiviFontsUploadAbility.php – final, implements Ability, RequiresDiviFeatures; lit/divi-fonts-upload
public function __construct(FontCatalog $catalog, FontInstaller $installer, RemoteFileFetcher $fetcher, ChangeLog $log, Limits $limits);
public const MAX_FILE_BYTES = 5 * 1024 * 1024; public const OBJECT_TYPE = 'divi_font';
// diviFeatures() = [FontUpload]; isDirect() = false; annotations() = Annotations::write(false); Gruppe divi (Task 9)
```
Verdrahtung in Task 9: `new DiviFontsUploadAbility($fontCatalog, new FontInstaller(), new RemoteFileFetcher(), $this->log, new Limits())` (`Limits` liest die Option bei jedem Aufruf; `DiviIntegration` hat bisher keine Instanz). Tabellenzeile für `DiviToolFeaturesTest`: `'lit/divi-fonts-upload' => ['font-upload']`, Schreib-Tool.
- Keine Konstruktoränderung an bestehenden Klassen → keine Verdrahtungsänderung in diesem Task.

- [ ] **Step 9: Adapter in `DiviAdapters::CLASSES` aufnehmen**
In `src/Integrations/Divi/Release/DiviAdapters.php` den Import `use LIT\MCP\Integrations\Divi\Design\FontInstaller;` (alphabetisch bei den `Design`-Importen) ergänzen und `FontInstaller::class,` in `CLASSES` **direkt hinter `FontCatalog::class`** (Task 2) einfügen – Schriftliste und Upload stehen so im Bericht nebeneinander:
```php
FontCatalog::class,
FontInstaller::class,
```
- [ ] **Step 10: GREEN Adapter, erwartete rote Tabellen**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter FontInstallerTest`
Expected: `OK (10 tests, 31 assertions)`
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter 'FontInstallerTest|DiviFeatureAssignmentTest|DiviBoundaryTest|DiviReferenceTest|DiviCheckCommandTest'`
Expected: `Tests: 43, …, Failures: 6.` – genau `DiviFeatureAssignmentTest::testTheAssignmentIsThePinnedTable` (neue Zeile fehlt, Step 11), `DiviReferenceTest::testEveryMirrorAndEveryCallHasAnExpectedFingerprintAndEveryMirrorAReferenceSource` (Fingerabdrücke fehlen, Step 13) und vier `DiviCheckCommandTest::testUpdateReference…` (der Wegwerf-Theme-Ordner des Tests kennt den neuen Mirror nicht, Step 12). `DiviBoundaryTest` ist grün (der Adapter nutzt genau `ET\Builder\VisualBuilder\Fonts\FontsUtility` und `…\Hooks\HooksRegistration`; `wp_handle_upload_rest` und der Klassen-Konstantenname sind für `DiviTouches` keine Divi-Namen).
- [ ] **Step 11: Zuordnungstabelle anpassen**
In `tests/Unit/Integrations/Divi/Release/DiviFeatureAssignmentTest.php` den Import `use LIT\MCP\Integrations\Divi\Design\FontInstaller;` ergänzen und in `EXPECTED` direkt hinter dem Block von `FontCatalog::class` (gleiche Reihenfolge wie `CLASSES`) einfügen:
```php
FontInstaller::class => [
'FontsUtility::mime_types_font()' => ['font-upload'],
'HooksRegistration::check_filetype_and_ext_font()' => ['font-upload'],
'FontsUtility::font_add()' => ['font-upload'],
'FontsUtility::font_remove()' => ['font-upload'],
'Konstante ET\\Builder\\VisualBuilder\\Fonts\\FontsUtility::FONT_NAME_MAX_LENGTH' => ['font-upload'],
'Nachbau AiAgentImageUtility::install_to_custom_fonts()' => ['font-upload'],
],
```
Den Text `'all ten adapters, in report order'` in `testTheAssignmentIsThePinnedTable` auf die neue Zahl bringen (nach Task 2 und diesem Task: `'all thirteen adapters, in report order'`).
- [ ] **Step 12: `DiviCheckCommandTest` kennt den neuen Mirror**
`writeDivi()` legt für jeden Mirror eine Minimal-Quelle unter seinem echten Pfad an; `--update-reference` liest alle Mirrors. In `tests/Unit/Integrations/Divi/Cli/DiviCheckCommandTest.php` (auf dem Stand nach Task 2 – falls Task 2 dort schon einen Mirror ergänzt hat, zählen beide):

- [ ] **Step 18: GREEN**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter DiviFontsUploadAbilityTest`
Expected: `OK (18 tests, 178 assertions)`
- [ ] **Step 19: Gesamtlauf, Lint, Commit**
Die Ability ist noch nicht verdrahtet (Task 9); `DiviIntegrationTest`/`DiviToolFeaturesTest` bleiben unverändert grün.
Run: `composer test && composer lint`
Expected: OK – Basis von Task 7 + 35 Tests (8a: 7, 8b: 10, 8c: 18); im Prüflauf des Planers mit Platzhaltern für Task 1–2 auf dem Stand 2307027: `OK (3161 tests, …)` = 3121 + 40 (Tasks 7 und 8); Lint sauber.
```bash
cd /home/janniclas/Projekte/WordPress/wp-content/plugins/WP-LIT-MCP
git add src/Integrations/Divi/Design/DiviFontsUploadAbility.php \
tests/Unit/Integrations/Divi/Design/DiviFontsUploadAbilityTest.php
git commit -m "feat: lit/divi-fonts-upload – eigene Schriften von URLs hochladen (Probelauf mit SHA-256, confirm, Rücknahme bei Teilerfolg)" -m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"
```
### Task 9: Verdrahtung in `DiviIntegration`, Tabellen der Fähigkeiten, Protokoll-Label
**Files:**
- Modify: `src/Integrations/Divi/DiviIntegration.php`
- Modify: `src/Admin/LogObjects.php` (Label für den Objekttyp `divi_font`, falls dort je Typ ein Label steht – erst lesen)
- Modify: `tests/Unit/Integrations/Divi/DiviIntegrationTest.php` (Namensliste)
- Modify: `tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php` (Tabelle `EXPECTED`)
- Modify (nur falls ein Test den Objekttyp prüft): `tests/Unit/Admin/LogObjectsTest.php`
**Interfaces:**
- Consumes (so, wie die Tasks 2–8 sie tatsächlich gebaut haben – vor dem Verdrahten die echten Konstruktoren lesen): `ThemeOptionsAdapter()`, `FontCatalog()`, `FontInstaller()`, `RemoteFileFetcher()`, `Limits()` ohne Argumente; `DiviThemeOptionsGetAbility(ThemeOptionsAdapter)`; `DiviThemeOptionsUpdateAbility(DesignSystemWriter, ThemeOptionsAdapter, FontCatalog, DesignChange)`; `DiviFontsUploadAbility(FontCatalog, FontInstaller, RemoteFileFetcher, ChangeLog, Limits)`; `DiviVariablesSetAbility(…, FontCatalog $fonts, ?Closure $random = null)`; `ThemeOptionsRestorePlanner(DesignSystemWriter, ThemeOptionsAdapter)`.
- Produces: die drei Tools in `DiviIntegration::abilities()`, **eine** Instanz je Adapter pro Integration (Eigenschaften `$themeOptionsAdapter`, `$fontCatalog`, `$fontInstaller`); die in Task 5 und Task 6 inline eingeführten `new FontCatalog()`/`new ThemeOptionsAdapter()` werden durch die geteilten Eigenschaften ersetzt (`FontCatalog` hält die große Schriftliste je Instanz – Task 2 –, darum nur eine pro Request).
- [ ] **Step 1: Tests zuerst – Namensliste und Fähigkeitentabelle**
`tests/Unit/Integrations/Divi/DiviIntegrationTest.php`, in `EXPECTED` nach `'lit/divi-variables-set',` ergänzen:
```php
'lit/divi-theme-options-get',
'lit/divi-theme-options-update',
'lit/divi-fonts-upload',
```
`tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php`, in `EXPECTED` unter `// Design system (divi)` nach `'lit/divi-variables-set' => …` ergänzen – die Zeilen müssen genau die `diviFeatures()` der Abilities abbilden (zuerst `DiviThemeOptionsGetAbility::diviFeatures()`, `DiviThemeOptionsUpdateAbility::diviFeatures()` und `DiviFontsUploadAbility::diviFeatures()` lesen; die Erwartung unten ist die aus den Plänen der Tasks 4 und 8, die Tabelle ist der Vertrag und folgt dem Code, nicht umgekehrt):
```php
'lit/divi-theme-options-get' => ['theme-option-read'],
'lit/divi-theme-options-update' => ['theme-option-read', 'theme-option-write'],
'lit/divi-fonts-upload' => ['font-upload'],
```
Und in der zweiten Tabelle der Datei (jedem schreibenden Tool seine Schreib-Fähigkeit, Zeile mit `'lit/divi-colors-set' => 'color-write', …`) ergänzen:
```php
'lit/divi-theme-options-update' => 'theme-option-write', 'lit/divi-fonts-upload' => 'font-upload',
```
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter '/DiviIntegrationTest|DiviToolFeaturesTest/'`
Expected: FAIL – `DiviIntegrationTest` (Namensliste ohne die drei Tools) und `DiviToolFeaturesTest` (Tabelle nennt Tools, die es nicht gibt).
- [ ] **Step 2: Imports, Eigenschaften, Konstruktor**
`src/Integrations/Divi/DiviIntegration.php` – Imports (zu den vorhandenen `Design\`-Imports; `FontCatalog`, `ThemeOptionsAdapter` und `ThemeOptionsRestorePlanner` stehen nach Task 5/6 teilweise schon dort):
```php
use LIT\MCP\Integrations\Divi\Design\DiviFontsUploadAbility;
use LIT\MCP\Integrations\Divi\Design\DiviThemeOptionsGetAbility;
use LIT\MCP\Integrations\Divi\Design\DiviThemeOptionsUpdateAbility;
use LIT\MCP\Integrations\Divi\Design\FontCatalog;
use LIT\MCP\Integrations\Divi\Design\FontInstaller;
use LIT\MCP\Integrations\Divi\Design\ThemeOptionsAdapter;
use LIT\MCP\Integrations\Divi\Design\ThemeOptionsRestorePlanner;
use LIT\MCP\Integrations\Media\RemoteFileFetcher;
use LIT\MCP\Limits;
```
Eigenschaften neben `$colorsAdapter`/`$variablesAdapter`:
```php
private ThemeOptionsAdapter $themeOptionsAdapter;
private FontCatalog $fontCatalog;
private FontInstaller $fontInstaller;
```
Im Konstruktor nach `$this->variablesAdapter = new GlobalVariablesAdapter();`:
```php
$this->themeOptionsAdapter = new ThemeOptionsAdapter();
$this->fontCatalog = new FontCatalog();
$this->fontInstaller = new FontInstaller();
```
- [ ] **Step 3: Tools registrieren, geteilte Adapter verwenden**
In `abilities()`: die inline-`new FontCatalog()` des Variablen-Tools (Task 5) und `new ThemeOptionsAdapter()` des Restore-Planers (Task 6) durch `$this->fontCatalog` bzw. `$this->themeOptionsAdapter` ersetzen. Vorher (Restore, Planerliste):
```php
new ThemeOptionsRestorePlanner($this->designWriter, new ThemeOptionsAdapter())
```
nachher:
```php
new ThemeOptionsRestorePlanner($this->designWriter, $this->themeOptionsAdapter)
```
Vorher (Variablen-Tool, letztes Konstruktorargument vor `$random`):
```php
new FontCatalog()
```
nachher:
```php
$this->fontCatalog
```
Nach dem Eintrag `new DiviVariablesSetAbility( … ),` anfügen:
```php
new DiviThemeOptionsGetAbility($this->themeOptionsAdapter),
new DiviThemeOptionsUpdateAbility(
$this->designWriter,
$this->themeOptionsAdapter,
$this->fontCatalog,
$this->designChange()
),
new DiviFontsUploadAbility(
$this->fontCatalog,
$this->fontInstaller,
new RemoteFileFetcher(),
$this->log,
new Limits()
),
```
(Die Argumente des `DiviFontsUploadAbility`-Konstruktors folgen der von Task 8 tatsächlich gebauten Signatur; weicht sie ab, gilt der Code.)
- [ ] **Step 4: Protokoll-Label**
Run: `grep -n "divi_design\|divi_font\|divi_" src/Admin/LogObjects.php`
Steht dort je Objekttyp ein Label (z. B. `divi_design` → „Designsystem“), den Typ `divi_font` mit dem Label „Divi-Schrift“ ergänzen und im zugehörigen Test (`tests/Unit/Admin/LogObjectsTest.php`, falls vorhanden) eine Zeile; gibt es keine Typ-Liste, entfällt der Schritt (im Bericht vermerken).
- [ ] **Step 5: GREEN, Gesamtlauf, Lint**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter '/DiviIntegrationTest|DiviToolFeaturesTest|IntegrationRegistryTest|ToolNamingTest/'`
Expected: PASS.
Run: `composer test && composer lint`
Expected: alle Tests grün, phpcs ohne Befund. Schlägt ein Test fehl, der Tool-Namen oder Beschreibungen prüft (`ToolNamingTest`, Exposure-/Guide-Tests), zuerst lesen, was er verlangt (indirekte Tools heißen in Texten `lit/<name>`), und den Text der Ability anpassen, nicht den Test.
Run: `grep -rn "Etappe 4d\|folgen mit Etappe\|mit 4d" src docs/guides | grep -v "docs/superpowers"`
Expected: keine Treffer, die behaupten, Theme-Optionen/Schriften/Restore von `theme_options` fehlten. Treffer in Guides, die nur auf spätere Guides (4e) verweisen, bleiben.
- [ ] **Step 6: Commit**
```bash
git add src/Integrations/Divi/DiviIntegration.php src/Admin/LogObjects.php tests/Unit/Integrations/Divi/DiviIntegrationTest.php \
tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php
git commit -m "feat: Theme-Optionen und Schriften-Upload in der Divi-Integration; je ein geteilter Adapter" -m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"
```
(`git add` nur die tatsächlich geänderten Dateien; `LogObjects`/`LogObjectsTest` nur, wenn Step 4 sie geändert hat.)
### Task 10: Smoke gegen echtes Divi (Theme-Optionen, Schriften-Upload, Restore)
**Files:**
- Create: `tests/Integration/divi-theme-fonts-smoke.sh`
**Interfaces:**
- Consumes: die Tools `lit/divi-theme-options-get`, `lit/divi-theme-options-update`, `lit/divi-fonts-upload`, `lit/divi-design-snapshots`, `lit/divi-design-restore` über den OAuth-Endpunkt und die Hilfen aus `tests/Integration/lib.sh` (`connect`, `ability`, `error_code`, `pass`, `fail`, `finish`, `guard_exit`, `cleanup_app_passwords_for`).
- Produces: ein Skript, das 4d gegen Divi 5.15.1 prüft und alles, was es ändert (`et_divi` byte-genau, `et_uploaded_fonts` samt Dateien), im EXIT-Trap zurücksetzt.
Das Skript wird ausgeführt und – wie in Plan 4c – anhand der echten Antworten korrigiert. Die Feldnamen der Antworten (`.__error | fromjson`, `.fields`, `.snapshots[]`) kommen aus dem Stand der Tools nach Task 9; stimmt eine Annahme nicht, wird das Skript berichtigt (nicht die Prüfung gelockert). Die Prüfungen selbst sind verbindlich.
- [ ] **Step 1: Das Skript anlegen**
Datei `tests/Integration/divi-theme-fonts-smoke.sh`:
```bash
#!/usr/bin/env bash
# End-to-end checks of Etappe 4d (Divi theme options: read, change, unknown font with suggestions, reset to default,
# snapshot + restore; custom font upload from a public URL) through the OAuth-protected endpoint against the real
# Divi. Runs INSIDE the DDEV web container:
# cd /home/janniclas/Projekte/WordPress && timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-theme-fonts-smoke.sh
# Needs network access from the container (fetches one small woff2 from fonts.gstatic.com). The EXIT trap puts the
# options et_divi and et_uploaded_fonts back byte-exact (serialized, base64 through the environment), removes the
# uploaded font with Divi's own FontsUtility::font_remove (files included) and fails the script when a restore fails.

- [ ] **Step 3: In DDEV ausführen und korrigieren**
Vorbereitung: `cd /home/janniclas/Projekte/WordPress && ddev exec wp plugin list` notieren, dann `ddev exec wp plugin deactivate postlos asynclistry` (nur falls aktiv); nach den Läufen den notierten Zustand wiederherstellen.
Run: `cd /home/janniclas/Projekte/WordPress && timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-theme-fonts-smoke.sh`
Expected: `ALL CHECKS PASSED`. Schlägt eine Prüfung fehl, die Antwort der Ability lesen (`fail` druckt sie): Ein Skriptfehler (Feldname, Quoting, jq-Pfad) wird im Skript berichtigt – Prüfung bleibt; ein Produktfehler (das Tool tut gegen echtes Divi etwas Falsches) wird NICHT im Skript versteckt, sondern mit Diagnose (Antwort, erwartet/ist, Verdacht mit Datei:Zeile) berichtet (DONE_WITH_CONCERNS). Schritt 5 vergleicht die drei Schlüssel nach dem Restore mit dem erfassten Original (`LIT_THEME`); der Snapshot aus Schritt 2 entstand vor jeder Änderung des Laufs, deshalb müssen alle drei Schlüssel exakt (vorhanden mit gleichem getypten Wert oder fehlend) dem Original entsprechen.
Danach prüfen, dass nichts übrig ist: `et_divi` und `et_uploaded_fonts` byte-identisch zum Zustand vor dem Lauf (`ddev exec wp eval 'echo md5(serialize(get_option("et_divi")));'` vor und nach dem Lauf), keine Schrift „LIT Smoke …“, keine Dateien `LIT-Smoke*` oder `*Roboto*` neu in `wp-content/uploads/et-fonts/`.
Run zusätzlich: `divi-release-smoke.sh` (erwartet jetzt 16 Fähigkeiten), `divi-colors-variables-smoke.sh`, `divi-presets-smoke.sh`, `divi-presets-assign-smoke.sh` – alle `ALL CHECKS PASSED`; und `ddev exec wp --user=<Admin> lit-mcp divi-check` mit Exit-Code 0 (alle Fähigkeiten nutzbar; die neuen Fingerabdrücke aus Task 2 und 8 sind schon committet).
- [ ] **Step 4: Commit**
```bash
git add tests/Integration/divi-theme-fonts-smoke.sh
git commit -m "test: Smoke für Theme-Optionen und Schriften-Upload gegen Divi 5.15.1" -m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"

### Task 11: Recherche ablegen, Notizen, Spec, Gesamtverifikation und Abschluss
**Files:**
- Create: `docs/superpowers/notes/2026-10-19-etappe-4d-divi-recherche.md` (die Divi-5.15.1-Recherche; Kopie der Planer-Notiz, redaktionell auf die Entscheidungen W1–W14 abgestimmt)
- Modify: `docs/superpowers/notes/2026-09-28-etappe-4-divi-formate.md` (Nachtrag „Etappe 4d“ nach dem Nachtrag 4c)
- Modify: `docs/superpowers/specs/2026-10-16-etappe-4-designsystem-design.md` (§8.1, §8.2, §10)
- Modify: `docs/superpowers/notes/2026-09-28-etappe-4-entscheidungen-entwurf.md` (Abschnitt „Etappe 4d“ mit den Rulings und den offenen Punkten)
- Modify: `docs/superpowers/notes/2026-10-18-divi-faehigkeiten.md` (Abschnitt „Offen“: Theme-Optionen-Fähigkeiten erledigt)
- Modify: Memory `etappe-4-stand` (außerhalb des Repos, `/home/janniclas/.claude/projects/-home-janniclas-Projekte-WordPress-wp-content-plugins-WP-LIT-MCP/memory/etappe-4-stand.md`)
**Interfaces:**
- Consumes: alles aus den Tasks 1–10.
- Produces: grüne Suite, grüne Smokes, Gesamtreview ohne offene wichtige Befunde, nachgeführte Spec und Notizen, aktualisierter Stand.
- [ ] **Step 1: Recherche und Nachträge schreiben**
1. Die Recherche (`…/scratchpad/research-4d-divi.md`, falls die Datei fehlt: aus Plan und Code neu fassen) als `docs/superpowers/notes/2026-10-19-etappe-4d-divi-recherche.md` ablegen.
2. Formate-Nachtrag „Divi 5.15.1 – Theme-Optionen und Schriften (Etappe 4d, 2026-10-19)“ in `2026-09-28-etappe-4-divi-formate.md` nach dem Nachtrag 4c: die zwölf Befunde der Recherche (Abschnitt 0) in einer Liste, je ein Satz, mit Verweis auf die Recherche für Zeilen.
3. Spec: §8.2 – der Nachbau des `et_uploaded_fonts`-Eintrags („eigener Sideload, … Nachbau mit Fingerabdruck“) ersetzen durch „Installation über `FontsUtility::font_add()` im Prozess (`action: wp_handle_upload_rest`, wie Divis KI-Pfad), Mirror `font-install`“; Formate `woff2`, `woff`, `ttf`, `otf`; §8.1 – `body_header_style` nimmt einen Wert, `null` setzt auf den Divi-Standard zurück; §10 – Zeile „Farben, Presets schreiben, Restore, Fonts-Upload“ trennen: Fonts-Upload = `upload_files` + `edit_theme_options` + Divi-Recht `custom_fonts_management`; Theme-Optionen = `edit_theme_options` + `theme_customizer`.
4. Entscheidungsnotiz: Abschnitt „Etappe 4d (Plan 2026-10-19-etappe-4d-theme-optionen-schriften.md)“ mit W1–W14 in je einem Satz und der Liste der offenen Folgepunkte: Schriftprüfung in Preset-/Modul-Attributen (nicht Teil von 4d), `lit/divi-fonts-list`/Schriftsuche (Vorschläge nur in Fehlern), Entfernen hochgeladener Schriften (A2), `eot`.
5. `2026-10-18-divi-faehigkeiten.md` „Offen“: den Punkt zu `DesignArea::feature()` für Theme-Optionen als erledigt kennzeichnen (Fähigkeiten `theme-option-read`/`-write`, `font-upload`).
- [ ] **Step 2: Suite, Lint, Divi-Prüfung**
Run: `composer test && composer lint`
Expected: alle Tests grün (3121 + die neuen), phpcs ohne Befund.
Run: `cd /home/janniclas/Projekte/WordPress && ddev exec wp --user=<Admin> lit-mcp divi-check`
Expected: Exit-Code 0; die drei neuen Fähigkeiten „Theme-Optionen lesen“, „Theme-Optionen schreiben“, „Schriften hochladen“ erscheinen als nutzbar.
- [ ] **Step 3: Gesamtreview (zwei unabhängige Opus-Reviews parallel)**
Dispatch (zwei Subagents, Modell Opus; je mit dem Paket `scripts/review-package PLAN BASE HEAD` über den ganzen Plan und den Rulings W1–W14):
1. Fachreview: Korrektheit gegen Plan und Spec, Sicherheit (SSRF-Pfad über `RemoteFileFetcher`, Dateityp/Magic Bytes, Größenlimit, Temp-Dateien immer gelöscht, Rechte in `permission()` UND `execute()`, Restore mit unlesbarer Snapshot-ID, `unset` statt `'none'`, Teilerfolg von `font_add`, `et_update_option`-Lost-Update, Cache-Aufrufe ohne angemeldeten Benutzer), Divi-Grenze und Mirror-Fingerabdrücke, Fähigkeitszuordnung je Tool.
2. `anthropic-skills:clean-code-review` (Quick) über die neuen und geänderten Klassen; bekannte Folgepunkte aus 4a–4c nur nennen, wenn 4d sie verschlimmert.
Wichtige und größere Befunde in EINER Fix-Welle (Sonnet) beheben, danach EIN scoped Re-Review (Sonnet); Kleinigkeiten in die Ledger-Notiz.
- [ ] **Step 4: Memory nachführen**
`etappe-4-stand.md` und `MEMORY.md` aktualisieren: 4d fertig (HEAD, Testzahl, Datum), nächster Schritt Plan 4e (Schleifen-Inhalte G12, Guides `divi-design-system`/`divi-shortform`/`workflows`, Security-Audit, Version); aus 4d offene Punkte anhängen.
- [ ] **Step 5: Abschluss**
`git status` sauber; nichts pushen oder mergen ohne Auftrag. Dem Nutzer berichten: Testzahl, Smoke-Ergebnisse, Befunde und Rulings, und fragen, ob gemergt/gepusht werden soll.

## Anhang: Abweichungen der Task-Autoren vom Schnittstellenvertrag (geprüft, im Plan berücksichtigt)
Die Autoren haben ihre Tasks in Kopien des Repos mit Stand-ins für fremde Tasks ausgeführt. Verbindlich bleibt der Taskinhalt; bei Zählungen (Tests, Adapter, Fingerabdrücke) gilt beim Umsetzen der echte Stand.
### Tasks 1-2
- **B1 (Ergänzung des Vertrags):** `ThemeOptionsAdapter` bekommt zusätzlich `public const SANITIZERS` (Whitelist-Schlüssel in W2-Reihenfolge => Name des Divi-/WordPress-Sanitizers). Grund: Task 2 kommt vor `ThemeOptionSpec` (Task 3), `read()`/`write()` brauchen die Whitelist, und die Zuordnung Schlüssel → Sanitizer ist Divi-Wissen, das an die Divi-Grenze gehört (der Vertrag gibt `ThemeOptionSpec::definition()` kein Sanitizer-Feld). Damit stehen die 20 Schlüssel zweimal (`SANITIZERS`, `ThemeOptionSpec::KEYS`); Task 3 sollte in `ThemeOptionSpecTest` `self::assertSame(ThemeOptionSpec::KEYS, array_keys(ThemeOptionsAdapter::SANITIZERS))` aufnehmen (die Konstante zu lesen ruft kein Divi; `ThemeOptionSpec` selbst bleibt rein).
- **B2 (Signatur beibehalten, Parameter ungenutzt):** `DesignRights::themeOptions(DesignSystemWriter $writer, ThemeOptionsAdapter $options)` behält die Vertrags-Signatur, fragt `$writer` aber nicht: die Rechte für Theme-Optionen sind laut Global Constraints `edit_theme_options` + `et_pb_is_allowed('theme_customizer')`, kein Visual Builder (Divis Customizer fragt ihn nicht). Der Test pinnt das (`canUseVisualBuilder` `never()`). Den Parameter zu streichen hätte die Aufrufe der parallel geplanten Tasks 4/6 gebrochen; Task 11 (Gesamtreview) kann ihn samt Aufrufern entfernen.
- **B3 (zusätzliche Testdatei):** `tests/Unit/Integrations/Divi/Cli/DiviCheckCommandTest.php` ist nicht in der Dateistruktur des Plans genannt, muss aber mit dem neuen Nachbau angepasst werden (Temp-Theme-Stand-in für `functions.php`, „7 Fingerabdrücke“) – Step 9.
- **B4 (Tests ohne Mockery-Alias):** Die Adapter-Tests brauchen kein `Mockery::mock('alias:…')`: alle Divi-Symbole sind Funktionen (Brain Monkey in eigenem Prozess) bzw. der vorhandene Stub `ET_Core_PageResource`. Die Global Constraint „Adapter-Tests ersetzen Divi-Klassen per Alias“ greift erst bei `FontInstaller` (Task 8, `FontsUtility`/`HooksRegistration`).
- **B5 (Grenzen für Task 11/Notiz):** `FontCatalog::reserved()` enthält Google-Schriften nur, wenn Google Fonts eingeschaltet sind (`et_builder_get_google_fonts()` liefert sonst `[]`, Divis `font_add` prüft ebenso) – ein Upload namens „Roboto“ ist bei abgeschalteten Google Fonts möglich. `names()` ist je Instanz gecacht; eine im selben Request hochgeladene Schrift ist darin erst mit einer neuen Instanz sichtbar (Upload und Schriftprüfung laufen in getrennten Requests).
### Tasks 3
- **`check()` lehnt `none` (ohne Beachtung der Schreibweise) bei Schrift-Schlüsseln ab.** Der Auftrag nennt es nicht, W3 verlangt aber „`'none'` und `false` werden abgelehnt“; `check()` ist die einzige Stelle ohne Divi-Aufruf, die das kann. Meldung: „… `none` ist kein Schriftname; null setzt auf Divis Standardschrift zurück.“ Außerdem wird ein Schriftname vor der Prüfung getrimmt (`" Lato "` ist gültig), `normalize()` liefert den getrimmten Namen.
- **`definition()` enthält für `tablet_*`/`phone_*` den Standard 14 bzw. 30** (was Divis CSS-Leser bei gar nichts Gespeichertem annehmen) plus `inherits`; der Standard des Customizers ist dynamisch (`et_get_option('body_font_size', '14')`). `effective()` nutzt `inherits` zuerst, der feste Standard greift nur am Ende der Kette. `body_header_style` und die vier Schriften haben Standard `null` (Divi: `''` bzw. `false`/`'none'`), `heading_font_weight`/`body_font_weight` `'500'` als String, `body_header_height` `1.0` (float).
- **Schrift-Stärke (`weight`)** akzeptiert in `check()` auch eine Ganzzahl (`500`), `normalize()` liefert immer den String (`'500'`), weil Divi so speichert. Ein Float (`500.0`) wird abgelehnt.
- **`effective()` wertet einen gespeicherten Wert nicht gegen die Bereiche** (Divi klemmt auch nicht; ein alter Wert 40 für `body_font_size` bleibt 40) und behandelt `false`, `null`, `'none'`, leere Namen und Nicht-Zahlen als „nicht gesetzt“; gespeicherte Ziffern-Strings werden in den Typ des Schlüssels gewandelt. Task 4 darf deshalb `effective()` direkt auf das Ergebnis von `ThemeOptionsAdapter::read()` anwenden.
- **`ThemeOptionBook::with()` wirft `InvalidArgumentException`** bei einem Schlüssel außerhalb der Whitelist (Task 4 prüft vorher mit `isKey()`); `fromDivi()` ignoriert sie dagegen stillschweigend (defensiv, Auftrag). `with($key, false)` ist erlaubt (Divis Standardschrift im Snapshot).
- **`FontSuggest` ist bytebasiert beim Abstand** (`levenshtein` kennt kein UTF-8): bei Umlauten zählt ein Zeichen als zwei Abstandseinheiten; die Rangfolge Präfix/Teilstring nutzt `mb_*` und ist unberührt. Die Eingabeliste wird dedupliziert, der Name getrimmt; leerer Name oder `$limit < 1` ergeben `[]`.
- Keine Konflikte mit Divi gefunden: alle geprüften Bereiche, Schritte und Standards (Zeilen 1903–2561 von `functions.php`) stimmen mit Tabelle A überein. Risiko: Bereiche und Standards sind Literale – ändert Divi sie, schlägt nur der Mirror `customizer-typography` (Task 2) an, nicht dieser Test.
### Tasks 4-6
1. **`DiviThemeOptionsGetAbility::__construct(ThemeOptionsAdapter $options)` – ohne `?FontCatalog`** (Vertrag: `(ThemeOptionsAdapter, ?FontCatalog = null)`). Das Lesetool braucht die Schriftliste nicht. Sie kostet 1,3 MB, und ihre Aufrufe tragen laut W1 `theme-option-write`. Mit ihr bräuchte das Lesetool also eine Schreibfähigkeit. Task 9 verdrahtet mit einem Argument.
2. **Neue Klasse `FontCheck`** (nicht in der Dateistruktur): Sie hält die gemeinsame Meldung „unbekannte Schrift … ähnlich: …“ für Theme-Optionen (Task 4) und Schrift-Variablen (Task 5), damit die Meldung nicht doppelt gepflegt wird. Sie ist rein bis auf die übergebenen `FontCatalog`-Methoden.
3. **`ThemeOptionsArea` hat zusätzlich `public const SITE_WIDE` und `public static same()`.** Beide sind gemeinsame Bausteine für das Update-Tool und den Restore-Planer.
4. **Reihenfolge der Prüfung bei den vier Schriftschlüsseln:** erst `ThemeOptionSpec::check`, dann `FontCatalog` mit Vorschlägen, dann Divis Sanitizer. Der Auftrag nannte den Sanitizer vor der Schriftliste. `et_sanitize_font_choices` liefert bei unbekannten Namen aber nur `false`, und die Vorschläge kämen dann nie.
5. **`'none'`/`false` lehnt das Update-Tool selbst ab**, vor `ThemeOptionSpec::check`, mit dem Hinweis auf `null`. Lehnt auch `check()` (Task 3) sie ab, gewinnt die Meldung des Tools. Das ist kein Konflikt.
6. **Annahmen an Task 3, auf die sich die Tests stützen:**
- `ThemeOptionBook::fromDivi()` und `ThemeOptionDiff::between()` liefern Schlüssel bzw. Zeilen in der Reihenfolge von `ThemeOptionSpec::KEYS`. Die Diff-Reihenfolge legt der Vertrag nicht fest, die Tests vergleichen sie aber.
- `definition()['type']` ist bei den Größen `'int'`, und `min`/`max` von `body_font_size` sind `10`/`32` (int).
- `check()` lehnt `'bold'` (Stil), `99` (Textgröße) und `'breit'` (Spaltenabstand) ab und nimmt `'18'` an.
- `effective()` vererbt W3-gemäß: Ist `tablet_body_font_size` nicht gesetzt, gilt der wirksame `body_font_size`.
Weicht Task 3 ab, gehören die Fixtures angepasst, nicht der Code.
7. **Annahmen an Task 2:**
- `DesignRights::themeOptions()` fragt `current_user_can('edit_theme_options')` und `ThemeOptionsAdapter::canCustomize()`. Die Test-Fakes erlauben zusätzlich `DesignSystemWriter::canUseVisualBuilder()` (→ true). Nutzt Task 2 weitere Methoden, braucht der Fake ein `allows()`.
- `ThemeOptionsAdapter::write()` liefert das Zurückgelesene. Seine eigene strenge Prüfung (RuntimeException) bleibt. `ThemeOptionsArea::verify()` ist die zweite Prüfung, auch für Restore und Rollback.
- Für die minimale Änderung in `DiviIntegration` (Task 5) nehme ich an, dass `FontCatalog` sich ohne Argumente bauen lässt. Hat sein Konstruktor Parameter, gelten dort die Argumente aus Task 2.
8. **`ThemeOptionsRestorePlanner::__construct(DesignSystemWriter, ThemeOptionsAdapter)`.** Diese Signatur legt der Vertrag nicht fest. Sie folgt dem Muster der Farb-/Variablen-Planer, und Task 9 verdrahtet sie.
9. **Hauptfarben in `theme-options-get`:** Es gibt nur einen Hinweis in `notes`, keine Werte. Das Tool braucht dafür also keinen neuen Leser im Adapter.
### Tasks 7-8
- **D1 `RemoteFileFetcher`-Schnittstelle:** `allows(string): bool` und `fetch(…): ?array` (`null` = fehlgeschlagen, Grund nur im Log) statt einer Methode mit `WP_Error`. Grund: die Meldungen an den Client unterscheiden sich (Medien `validation_failed` mit `url` wie bisher, Schriften `validation_failed`/`font_fetch_failed` mit `files.<Format>`); die `Content-Length`-Vorabprüfung bleibt medienbezogen in `MediaImporter` (Schriften prüfen die Dateigröße nach dem Abschneiden bei Limit + 1). `MediaImporter` behält seinen Konstruktor und erzeugt den Fetcher selbst – keine Verdrahtungsänderung, `MediaImporterTest` unverändert.
- **D2 `FontNameRules::check()` hat einen optionalen dritten Parameter `int $maxLength = 100`;** die Ability übergibt `FontInstaller::nameMaxLength()` (= `FontsUtility::FONT_NAME_MAX_LENGTH`), so wird die Divi-Konstante wirklich gelesen und nicht nur im Manifest genannt. Zusätzlich `FontNameRules::taken()` (öffentlich), damit die Ability einen belegten Namen als `conflict` (409) statt als Validierungsfehler meldet; `check()` mit gefülltem `$reserved` meldet die Kollision weiterhin als Text (Vertrag).
- **D3 `FontInstaller` zusätzlich:** `public const FORMATS` und `nameMaxLength()`. `formats()` schneidet `FORMATS` mit `FontsUtility::mime_types_font()` (W8), **nicht** mit `et_pb_get_supported_font_formats()` (Standard nur ttf/otf) – woff/woff2 sind nach W8 gewollt; das Manifest nennt diese Funktion deshalb nicht.
- **D4 Teilerfolg:** `install()` entfernt bei Teilerfolg nicht selbst, sondern liefert die gespeicherten Endungen (Vertrag `@return list<string> installierte Endungen`); die Ability vergleicht und ruft `remove()` über `Rollback::attempt()` (W8: „Abweichung → font_remove und Fehler“). Wirft `install()`, ist nichts gespeichert (Divi speichert erst nach mindestens einer erfolgreichen Datei, Vorprüfung aller Dateien vor `font_add`) – dann kein `remove()`.
- **D5 `DiviCheckCommandTest` ist betroffen** (nicht im Dateiplan genannt): der neue Mirror braucht eine Minimal-Quelle im Wegwerf-Theme, die Zahl der Fingerabdrücke steigt. Fügt Task 2 den Mirror `customizer-typography` hinzu, ändert Task 2 dieselbe Stelle; Step 12 rechnet relativ dazu.
- **D6 Fehlercodes:** `font_fetch_failed` und `font_invalid` mit Status 400 und `fields`; hat ein Aufruf beide Arten, gilt `font_fetch_failed` mit allen Feldern. Größenüberschreitung ist `font_invalid` („größer als N MB“).
- **D7 Protokoll-Objekttyp `divi_font`:** `src/Admin/LogObjects.php` kennt ihn nicht und zeigt ihn als Code (`divi_font Inter Display`); ein Label kann Task 11 ergänzen.
- **Prüflauf:** im Arbeitsstand des Planers mit Platzhaltern für `DiviFeature::FontUpload` (inkl. angepasstem `DiviFeatureTest`), `FontCatalog` (ohne Divi) und `DesignRights::fonts()`; `fingerprints.json` und `font-install.txt` dort aus den Divi-5.15.1-Quellen mit `DiviReference`/`SourceFingerprint` erzeugt (nicht über DDEV). Die RED/GREEN-Zahlen oben stammen aus diesen Läufen.
