# Etappe 4c – Designsystem: Farben und Variablen schreiben – 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 legt globale Farben und Variablen an und ändert sie (`lit/divi-colors-set`, `lit/divi-variables-set`), entfernt Verweise auf eine Variable überall, indem er sie durch ihren Wert ersetzt (`lit/divi-design-detach` mit `variable`), und stellt Snapshots der Bereiche `colors` und `variables` wieder her (`lit/divi-design-restore`) – alles mit Probelauf, `confirm`, `design_rev`, Snapshot vor jeder Änderung und Zurücklesen nach dem Schreiben.
**Architecture:** Die 4a-Pipeline `DesignChange` bleibt unverändert; neu sind zwei `DesignArea`-Implementierungen (`ColorArea`, `VariableArea`) mit reinen Bestandsklassen (`ColorBook`, `VariableBook`, jeweils mit Diff und Wertprüfung) und zwei kleinen Divi-Adaptern (`GlobalColorsAdapter`, `GlobalVariablesAdapter`) mit eigenen Fähigkeiten (`color-write`, `variable-write`). Fundstellen von Farben/Variablen in Seiten liefert eine neue `ReferenceUsageQuery` für das vorhandene `GlobalUsages`; Variablen-Detach nutzt den vorhandenen `PageRewriter` mit einer neuen `NodeRewrite`-Strategie und den Preset-Schritt der 4b-Pipeline. `DiviDesignRestoreAbility` wird auf Planer je Bereich umgestellt (`RestorePlanner`), `DiviDesignDetachAbility` verwendet statt eines Arrays ein `DetachTarget`.
**Tech Stack:** PHP ≥ 8.1, WordPress 7.x, Divi 5.15.1 (`GlobalData::get_global_colors/set_global_colors/sanitize_global_colors_data/get_global_variables/set_global_variables`, `et_pb_is_allowed` – nur über die zwei 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` (§4, §5, §6.8 Variable, §7, §10, §11, §13, §14 Schritt 6), Entscheidungen `docs/superpowers/notes/2026-09-28-etappe-4-entscheidungen-entwurf.md` (G2, G5, G6, A4, A7, A8 – verbindlich), Datenformate `docs/superpowers/notes/2026-09-28-etappe-4-divi-formate.md` (§1 Farben, §2 Variablen, §5 Caches, §6 Rechte, §7 Abweichungen), Divi-Fähigkeiten `docs/superpowers/notes/2026-10-18-divi-faehigkeiten.md`, Pläne 4a/4b (`2026-10-16-etappe-4a-presets.md`, `2026-10-18-etappe-4b-zuweisen.md`) als Vorbild; der Code ist maßgeblich, wo er von den Plänen abweicht.
**Voraussetzung:** Branch `etappe-4`, Stand 63389f3 (4a, 4b und Divi-Fähigkeiten fertig), 2877 Unit-Tests grün (`composer test`), `composer lint` sauber.
**Teil von Etappe 4:** 4a, 4b (fertig) → **4c (dieser Plan)** → 4d Theme-Optionen und Schriften → 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 schreiben nur in die DDEV-Datenbank und stellen im EXIT-Trap alles wieder her, was sie ändern (Farben, Variablen, Presets, Seiten).
- 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;`, höchstens 120 Zeichen je Zeile, `declare(strict_types=1);`. 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). Alle übrigen neuen Klassen sind **reines PHP** ohne WordPress- und Divi-Aufrufe (Abhängigkeiten als Objekt oder `Closure` injiziert); Ausnahmen nennt der Task ausdrücklich (`ReferenceUsageQuery` darf wie `PresetUsageQuery` nur `$db->prepare()`/`$db->esc_like()` am übergebenen `\wpdb` nutzen).
- **Pipeline (Spec §4):** Jede Änderung eines Bereichs läuft durch `DesignChange::run()`: Rechte → Eingabe prüfen (alle Fehler gesammelt als `validation_failed` mit Feldpfaden) → neuen Bestand berechnen → Probelauf (`confirm_required` mit `diff`, `design_rev`, `affected`, `warnings`) → mit `confirm: true` und `design_rev` Sperre, Snapshot, Schreiben über Divi, Zurücklesen und `verify`, Protokoll. Keine Ausnahme für „harmlose“ Änderungen. Mehrere Einträge je Aufruf (A4, höchstens 50).
- **Werte (D7-Prinzip):** Farbwerte und Variablenwerte werden vom Plugin geprüft (`ColorValue`, `VariableValue`) und erst dann an Divi gegeben; Divis eigenes Sanitize (`sanitize_global_colors_data`, `sanitize_global_variables_data` innerhalb von `set_global_variables`) läuft zusätzlich. Referenzen auf andere Farben entstehen nur über `VariableRef::serialize('color', <id>, <settings>)`, nie aus Client-Text.
- **Rechte (Spec §10):** Farben = `edit_theme_options` **und** Divi-Rolle „Visual Builder verwenden“ (strenger als Divi selbst); Variablen zusätzlich `et_pb_is_allowed('variables_manager')` (sonst täte Divi still nichts). Restore prüft die Rechte des Bereichs des Snapshots. Detach einer Variable = Rechte der Variablen **und** `edit_post` je Live-Fundstelle (Regeln P8/P8a des `PageRewriter`) und, weil Presets mitgeschrieben werden, `DesignRights::presets()`.
- **Exposition:** Neue Tools sind indirekt (über `mcp-adapter-execute-ability`), Gruppe `divi`, `Annotations::write`/`destructive` wie die Preset-Tools; Texte nennen indirekte Tools `lit/<name>` (ToolNamingTest); `docs/guides/overview.md` „Direkt sichtbar:“ bleibt unverändert. Guides folgen gesammelt mit 4e (Spec §14 Schritt 9); die Tool-Beschreibungen tragen die Reihenfolge Probelauf → `confirm`.
- **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 mit erwarteter Fehlermeldung, dann Code, GREEN. 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`).
- **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 12).
- 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 4c (Rulings, verbindlich)
- **V1 Variablen werden nie gelöscht, nur archiviert.** Divi 5.15.1 lehnt in `GlobalData::set_global_variables()` jeden Bestand ab, dem eine gespeicherte `gvid-`-ID fehlt (`validate_global_variable_ids()` → `global_variable_ids_missing`, 400). Echtes Löschen (Spec §7.2 `delete: true`) ist damit nicht möglich und entfällt; der Builder archiviert ebenfalls (`status: archived`, `order: ""`). Folgen: (a) `lit/divi-variables-set` kennt `status: active|archived`, kein `delete`, kein `in_use`; Archivieren einer verwendeten Variablen ist erlaubt und meldet die Fundstellen als Warnung (wie Farben deaktivieren, Spec §7.1); (b) **Restore** eines Snapshots stellt jede Variable des Snapshots her; Variablen, die erst nach dem Snapshot entstanden, bleiben **archiviert** erhalten (`VariableBook::restoredFrom()`), der Probelauf nennt sie als Warnung; (c) `lit/divi-design-detach` mit `variable` ist der Weg, eine Variable aus den Inhalten zu lösen, bevor man sie archiviert. Spec §7.2 und Entscheidungsnotiz werden entsprechend nachgeführt (Task 11).
- **V2 Zwei Fähigkeiten statt einer:** `DiviFeature::ColorWrite` (`color-write`, „Farben schreiben“) und `DiviFeature::VariableWrite` (`variable-write`, „Variablen schreiben“). Ein Bruch von `set_global_variables` sperrt so nicht das Farbenschreiben. `DesignArea::feature()` liefert je Bereich die eigene Fähigkeit; beide sind Schreib-Fähigkeiten (`isWrite()`). Die Tools deklarieren zusätzlich `DesignRead` (und das Detach-Tool die Seiten-/Bibliotheks-/Theme-Builder-Fähigkeiten wie bisher).
- **V3 Farben: Hauptfarben und Cache.** `GlobalData::get_global_colors()` liefert die fünf Customizer-Farben (`folder: customizer`, IDs `gcid-primary-color` … `gcid-link-color`, Optionen `accent_color`, `secondary_accent_color`, `header_color`, `font_color`, `link_color`) **vor** den gespeicherten Farben mit `lastUpdated` = jetzt, und `get_customizer_colors()` hat einen `static`-Cache ohne Reset. `GlobalColorsAdapter::read()` legt deshalb die Werte der fünf Hauptfarben aus der Option `et_divi` über das Ergebnis (nur wenn dort ein nicht leerer String steht) – sonst läse das Zurücklesen nach dem Schreiben im selben Request den alten Wert. `ColorBook` setzt `lastUpdated` der Hauptfarben auf `""` (flüchtig; `design_rev` und Snapshots bleiben stabil). Geschrieben werden Hauptfarben nur, wenn sich ihr Wert ändert (die Builder-Sicht `#2ea3f2` für `secondary_accent_color` weicht vom Customizer-Standard `#8800FF` ab, Formate §4). Hauptfarben lassen sich nicht deaktivieren und nicht umbenennen oder in einen Ordner schieben; nur `color` ändert sich.
- **V4 Schreibweg Farben:** normales Schreiben = nur geänderte und neue Einträge (`ColorBook::changedSince()`), durch `GlobalData::sanitize_global_colors_data()` und dann `set_global_colors($data, true)` (mischt; `true` heißt „bereits bereinigt“); Restore (`mayRemove = true`) = gesamter Snapshot durch `set_global_colors($data, false)` (ersetzt alle gespeicherten Farben, bereinigt selbst, schreibt die Hauptfarben zurück). Neue IDs `gcid-` + 10 Zeichen `[0-9a-z]`; `lastUpdated` im Format `Y-m-d\TH:i:s.v\Z`; `usedInPosts` bleibt `[]` (nur der Builder pflegt sie, Formate §1).
- **V5 Farbwerte:** `color` = Hex (`#rgb`, `#rgba`, `#rrggbb`, `#rrggbbaa`), `rgb()`/`rgba()`/`hsl()`/`hsla()`, ein Farbschlüsselwort (nur Buchstaben, 3–20 Zeichen) oder ein Platzhalter `{{color:<Name|ID|Alias>}}` **mit** `relative: {hue?, saturation?, lightness?, opacity?}` (Zahlen, `hue` −360…360, die übrigen −100…100). Der Platzhalter wird gegen den **geplanten** Bestand aufgelöst (auch Farben desselben Aufrufs, in Reihenfolge der `items`) und als `VariableRef::serialize('color', <gcid>, <settings>)` gespeichert. Zyklen und Tiefe über 10 (wie Divi) → `validation_failed`. `shortcut:` Wertebereiche der relativen Einstellungen sind die der Builder-Regler, nicht aus Divi-Code abgeleitet – im Code kommentieren.
- **V6 Variablenwerte (`VariableValue::check(type, value)`):** `numbers` = CSS-Ausdruck ohne `;`, `{`, `}`, `<`, `>`, Zeilenumbruch, höchstens 200 Zeichen, nicht leer; `strings` = beliebiger Text ohne Steuerzeichen außer Zeilenumbruch, höchstens 2000 Zeichen, nicht leer; `links` = `http(s)://`- oder `/`-URL, `mailto:`/`tel:` erlaubt, höchstens 2000 Zeichen; `images` = Anhang-ID (Ziffern) oder `http(s)://`-URL; `fonts` = Schriftname, 1–100 Zeichen ohne `;{}<>"'\\` (die Prüfung gegen Divis Schriftenliste folgt mit 4d). Aktive Variablen brauchen einen Wert (Divi: `global_variable_active_value_empty`). Der Typ `gradients` (neu in Divi 5.15) wird beim Lesen und Schreiben **unverändert durchgereicht**, das Tool legt ihn aber nicht an.
- **V7 Schreibweg Variablen:** `GlobalVariablesAdapter::read()` = `GlobalData::get_global_variables()` zurück in Speicherform (Gruppen und Einträge als Arrays, `allowedActions`, die Customizer-Schriften `--et_global_heading_font`/`--et_global_body_font` und die Gruppe `colors` entfernt, leere Gruppen weggelassen); `save($data, $expected)` ruft `GlobalData::set_global_variables($data, $expected)` mit dem Bestand, auf dem geplant wurde (Divis eigene Stale-Prüfung `global_variables_stale`), und macht aus einem `WP_Error` eine `RuntimeException` (die Pipeline rollt zurück). Ohne `variables_manager`/`edit_theme_options` tut Divi **still nichts** – darum prüft `DesignRights::variables()` vorher, und `VariableArea::verify()` fängt den Rest über das Zurücklesen.
- **V8 Fundstellen (`affected`):** Für geänderte, deaktivierte oder archivierte Einträge (nicht für neue) liefert `ReferenceUsageQuery` die Seiten, Bibliothekseinträge und Theme-Builder-Layouts, die die ID in einem `$variable(…)$`-Verweis nennen (über `GlobalUsages::reportFor()`, Rechte-Regeln wie `UsageReport`); Verwendungen in Presets und in relativen Farben stehen als `warnings`, nie als Sperre. Eine blockierte Live-Seite (ohne `edit_post`) verweigert das Schreiben wie bei Presets (`DesignChange::blocked()`, P8/P8a).
- **V9 Detach einer Variablen (A7, R10):** jeder ganze Wert `$variable({"type":"content","value":{"name":"<gvid>",…}})$` in den Attributen eines lesbaren Blocks wird durch den aktuellen Wert der Variablen ersetzt (bei `strings` mit `before`/`after` aus den Einstellungen: `before . Wert . after`; sonst ohne). Eingebettete Verweise (nicht der ganze Wert) bleiben stehen und werden als Hinweis gemeldet. Verschachtelte Verwendung in Presets (`attrs`, `styleAttrs`, `renderAttrs`) entfernt der Aufruf im selben Schritt über die Pipeline (Snapshot `presets`), wie bei Gruppen-Presets (4b R10). Farben haben kein Detach (sie werden nur deaktiviert).
- **V10 Restore je Bereich:** `DiviDesignRestoreAbility` bekommt eine Liste von `RestorePlanner` (`PresetRestorePlanner` = der bisherige Code unverändert verschoben, `ColorRestorePlanner`, `VariableRestorePlanner`); der Bereich ergibt sich aus der Snapshot-ID. Rechte und Fähigkeit sind die des Bereichs. Die Meldung „Snapshots dieses Bereichs lassen sich noch nicht wiederherstellen“ gilt nur noch für `theme_options` (4d).

### Task 1: Fähigkeiten `ColorWrite` und `VariableWrite` (V2)
Zwei neue Schreib-Fähigkeiten, damit ein Bruch von `set_global_variables` nicht das Farbenschreiben sperrt. Geprüft mit `grep -rn "PresetWrite\|preset-write\|elf Fähigkeiten\|Eleven\|eleven" src tests docs` und einem Probelauf der ganzen Suite mit den zwei neuen Fällen (Stand 63389f3): 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`, `FeatureStatusTest`, `DiviTabTest`, `DiviLockedTest`, `ReleaseGateTest`, `ReleaseResolverTest`, `CompatibilityMatrixTest`, `DiviCheckCommandTest` und `DiviEnvironmentComponentTest` rechnen mit `count(DiviFeature::cases())` oder nennen nur einzelne Fähigkeiten und bleiben unverändert grün. Außerhalb der Unit-Tests zählt nur `tests/Integration/divi-release-smoke.sh` die Fähigkeiten (Liste der IDs, „eleven“, `= "11"`). `docs/guides/overview.md` nennt Fähigkeiten nur als Beispiele (bleibt), die Fähigkeiten-Notiz folgt mit Task 11.
**Wegen des Zuordnungstests hat Task 1 keinen eigenen Commit:** seine Dateien werden im letzten Schritt von Task 2 zusammen mit den Adaptern committet (siehe `## ABWEICHUNGEN`, A1). Bis dahin ist genau `DiviFeatureAssignmentTest::testEveryFeatureIsServedByAtLeastOneRequirement` rot.
**Files:**
- Modify: `src/Integrations/Divi/Release/DiviFeature.php` (zwei Fälle, `isWrite()`, `label()`, Docblock von `isWrite()`)
- Modify: `tests/Unit/Integrations/Divi/Release/DiviFeatureTest.php`
- Modify: `tests/Integration/divi-release-smoke.sh` (13 statt 11 Fähigkeiten; läuft erst nach Task 2 grün, weil vorher die Signatur-Referenzen der neuen Aufrufe fehlen)
**Interfaces:**
- Consumes: `DiviFeature` (vorhanden).

### Task 2: Adapter `GlobalColorsAdapter`/`GlobalVariablesAdapter`, Manifest, Fingerabdrücke, `DesignRights` (V3, V4, V7)
Zwei kleine Adapter im Bereich „Designsystem“ – die einzigen Klassen, die Farben und Variablen über Divi schreiben – mit eigenem Manifest und der Fähigkeit des Bereichs als Vorgabe. Geteilte Divi-Aufrufe stehen wie bei `DesignSystemReader`/`DesignSystemWriter` (`GlobalPreset::get_data`) in **jedem** Manifest, das sie nutzt: `get_global_colors`/`get_global_variables` bleiben im Reader mit `design-read`/`page-read` und stehen hier zusätzlich mit `color-write` bzw. `variable-write`; `et_pb_is_allowed` bleibt in `DiviRoles` mit `roles` und steht hier mit `variable-write`. `DiviAdapters::calls()` führt jedes Symbol nur einmal (für die Signatur egal), `featuresOf()` gilt je Manifest. Kein Aufruf braucht eine eigene Fähigkeitsliste – die Vorgabe des Manifests reicht, weil nur die Schreibwege diese Adapter nutzen (das Designsystem-Tool liest weiter über `DesignSystemReader`).
Geprüft an `themes/Divi/includes/builder-5/server/Packages/GlobalData/GlobalData.php` (5.15.1): `get_global_colors(): array` (0 Parameter; Hauptfarben aus `get_customizer_colors()` mit `static $formatted_colors` vor den gespeicherten, `lastUpdated` = jetzt), `sanitize_global_colors_data(array $data): array` (1; verwirft Einträge mit leerem `color` oder ohne `gcid-`-Präfix), `set_global_colors(array $data, $already_sanitized = false): void` (2; schreibt Hauptfarben über `et_update_option` in `et_divi`, mischt bei `true` mit den gespeicherten, ersetzt bei `false`), `get_global_variables(): array` (0; Gruppen als `stdClass`, Einträge mit `allowedActions`, Gruppe `colors`, Customizer-Schriften `--et_global_heading_font`/`--et_global_body_font`), `set_global_variables(array $data, ?array $expected_variables = null): ?WP_Error` (2; ohne `edit_theme_options` oder `et_pb_is_allowed('variables_manager')` still `null`; vergleicht `$expected` **bereinigt** mit dem bereinigten Bestand → `global_variables_stale`, dann `global_variable_ids_missing`, dann `validate_global_variable_changes`), `et_pb_is_allowed($capabilities, $role = '')` in `includes/builder/core.php` (1). `sanitize_global_variables_data()` behält nur `gvid-`-IDs der Typen `numbers|strings|images|links|fonts|gradients` – darum filtert `read()` nach `gvid-` (das entfernt die Customizer-Schriften und jeden Fremdeintrag genau wie Divi) und lässt `colors` weg.
**Unit-Tests ohne Divi:** `GlobalData` fehlt in den Unit-Tests. Die Tests von `read()`/`save()` ersetzen die Klasse mit `Mockery::mock('alias:ET\Builder\Packages\GlobalData\GlobalData')` und laufen mit `@runInSeparateProcess` (ein Alias definiert die Klasse für den Rest des Prozesses; Vorbild für die eigene Prozess-Regel: `DiviPagesTest::testIsLinkableFollowsDivisPublicPostTypes`, `DiviThemeBuilderTest::testMissingDiviFunctionsAreRefusedBeforeWriting`). Ebenso der positive Fall von `canManage()` (Brain Monkey definiert `et_pb_is_allowed` sonst prozessweit, `DiviRolesTest`/`DiviIntegrationTest` verlassen sich auf ihr Fehlen). Beide Adapter sind – wie `DesignSystemReader`/`DesignSystemWriter` – **nicht `final`**, damit `DesignRightsTest` und die Bereiche (Tasks 6/7) sie mit Mockery ersetzen können (siehe `## ABWEICHUNGEN`, A2).
**Files:**
- Create: `src/Integrations/Divi/Design/GlobalColorsAdapter.php`
- Create: `src/Integrations/Divi/Design/GlobalVariablesAdapter.php`
- Create: `tests/Unit/Integrations/Divi/Design/GlobalColorsAdapterTest.php`
- Create: `tests/Unit/Integrations/Divi/Design/GlobalVariablesAdapterTest.php`
- Modify: `src/Integrations/Divi/Release/DiviAdapters.php` (beide Klassen nach `DesignSystemWriter::class`)
- Modify: `tests/Unit/Integrations/Divi/Release/DiviFeatureAssignmentTest.php` (gepinnte Tabelle, „ten adapters“)
- Modify: `src/Integrations/Divi/Release/fingerprints.json` (generiert, drei neue `sig:`-Schlüssel)
- Modify: `src/Integrations/Divi/Design/DesignRights.php` (`colors()`, `variables()`, private `designer()`)
- Modify: `tests/Unit/Integrations/Divi/Design/DesignRightsTest.php`
**Interfaces:**
- Consumes: `Manifest`, `Call`, `DiviAdapter`, `DiviAdapters::CLASSES`, `ReleaseGate::assertFeature()`, `DiviLocked`, `Errors::forbidden()`, `DesignSystemWriter::canUseVisualBuilder()` (alle vorhanden), `DiviFeature::ColorWrite`/`VariableWrite` (Task 1); Tests: `LIT\MCP\Tests\Unit\TestCase` (`assertToolError`), `ReleaseMatrices::uniform(ReleaseState, string)`, Brain Monkey `Functions\when()`.
- Produces:
- `class GlobalColorsAdapter implements DiviAdapter` – `manifest()`: Bereich `Manifest::DESIGN`, Aufrufe `GlobalData::get_global_colors` (0), `GlobalData::sanitize_global_colors_data` (1), `GlobalData::set_global_colors` (2), Schlüssel `et_divi`, Vorgabe `[DiviFeature::ColorWrite]`; `read(): array` = `get_global_colors()`, Hauptfarben mit dem Wert aus `et_divi` überlagert, wenn dort ein nicht leerer String steht (V3; kein Eintrag wird erfunden); `save(array $entries, bool $replace): void` – `ReleaseGate::assertFeature(ColorWrite)`, dann `sanitize_global_colors_data($entries)`; fehlt danach ein Eintrag → `RuntimeException('global colors refused: Divi dropped <IDs>')`, nichts geschrieben; sonst `set_global_colors($clean, ! $replace)` (V4: `false` → mischen, `true` → alles ersetzen).
- `class GlobalVariablesAdapter implements DiviAdapter` – `manifest()`: Aufrufe `GlobalData::get_global_variables` (0), `GlobalData::set_global_variables` (2), `et_pb_is_allowed` (1), keine Schlüssel, Vorgabe `[DiviFeature::VariableWrite]`; `read(): array` Speicherform (V7); `save(array $data, array $expected): void` – `ReleaseGate::assertFeature(VariableWrite)`, `set_global_variables($data, $expected)`, `WP_Error` → `RuntimeException('global variables refused: <code> <message>')`; `canManage(): bool` = `function_exists('et_pb_is_allowed') && et_pb_is_allowed('variables_manager')`.
- `DesignRights::colors(DesignSystemWriter $writer): ?WP_Error` – dieselben Rechte wie `presets()`, Meldungen mit „Farben“.
- `DesignRights::variables(DesignSystemWriter $writer, GlobalVariablesAdapter $variables): ?WP_Error` – erst wie `colors()` (Meldungen mit „Variablen“), dann `canManage()`, sonst `forbidden` „… erlaubt den Variablen-Manager nicht …“ mit Hinweis auf den Rollen-Editor.
- `presets()` verhält sich unverändert (gleiche Texte, jetzt über `designer($writer, 'Presets')`).

Run: `php -d memory_limit=512M vendor/bin/phpunit --filter 'DesignRightsTest|DiviPresets|DiviDesign'`
Expected: `OK` (die Preset-Tools sehen dieselben Meldungen wie vorher).
- [ ] **Step 11: Signatur-Referenzen in DDEV erzeugen**
`wp lit-mcp divi-check --update-reference` (`src/Integrations/Divi/Cli/DiviCheckCommand.php`) verlangt einen Administrator (`manage_options`, der Schreibtest legt eine Wegwerfseite an), schreibt nur, wenn außer „Fingerabdrücke“ alle Prüfschritte grün sind (Manifeste: die neuen Aufrufe existieren mit passender Argumentzahl; die fehlende Signatur-Referenz ist kein Manifest-Fehler, nur ein `reference-missing`-Problem), und nur in einer Entwicklungskopie mit `tests/` (`DiviReference::sourceDir()`). Es schreibt die Referenzquellen der Nachbauten (unverändert, keine neuen Mirrors) und `fingerprints.json` (Nachbauten + `sig:` jedes Aufrufs aus `DiviAdapters::calls()`).
Run:
```bash
cd /home/janniclas/Projekte/WordPress
ddev start
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 `✓` oder `✗` sein), dann `Referenz aktualisiert (6 Fingerabdrücke, 32 Signaturen). Smoke-Skripte laufen lassen, dann committen.` und die Fähigkeiten-Matrix; Exit-Code 0. Bricht WP-CLI mit Monolog-/Deprecation-Ausgaben ab, wie für die Smokes `postlos` und `asynclistry` vorher deaktivieren (`ddev wp plugin deactivate postlos asynclistry`) und danach wieder aktivieren (`ddev wp plugin activate postlos asynclistry`).
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:'
```
Expected: genau drei `+`-Zeilen und keine `-`-Zeile – `"sig:ET\\Builder\\Packages\\GlobalData\\GlobalData::sanitize_global_colors_data": "<sha256>"`, `"…GlobalData::set_global_colors": "<sha256>"`, `"…GlobalData::set_global_variables": "<sha256>"`; keine Änderung unter `tests/Fixtures/divi/reference`; `32`. Ändert sich ein anderer Schlüssel, **nicht committen**, sondern prüfen (installiertes Divi ≠ 5.15.1 oder eine Divi-Signatur hat sich geändert).
- [ ] **Step 12: Gesamtlauf, Lint, Freigabe-Smoke**
Run: `composer test && composer lint`
Expected: OK (alle Tests grün, auch `DiviReferenceTest` und `DiviFeatureAssignmentTest`), 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 drei neuen Aufrufe) und `ok - lit-site-status: thirteen features released (code), each with its tools`. Läuft nur mit deaktivierten Plugins `postlos` und `asynclistry`.
- [ ] **Step 13: Commit (Tasks 1 und 2)**
```bash
cd /home/janniclas/Projekte/WordPress/wp-content/plugins/WP-LIT-MCP

### Task 3: `ColorValue`, `ColorBook`, `ColorDiff` – reiner Farbbestand (V3, V5)
**Files:**
- Create: `src/Integrations/Divi/Design/ColorValue.php`, `ColorBook.php`, `ColorDiff.php`
- Test: `tests/Unit/Integrations/Divi/Design/ColorValueTest.php`, `ColorBookTest.php`, `ColorDiffTest.php` (alle neu, erben von `PHPUnit\Framework\TestCase`)
**Interfaces:**
- Consumes: `LIT\MCP\Abilities\Rev::of(string): string` (sha256, 12 Hex-Zeichen – dasselbe Verfahren wie `PresetBook::rev()`); `LIT\MCP\Integrations\Divi\Compose\VariableRef::serialize()`, `::typeOf()`, `::MARKER`, `::END` (nur öffentliche, reine Mitglieder; `serialize()` nur in den Tests); `DesignSystem::COLOR_ALIASES` (öffentliche Konstante: `primary` → `gcid-primary-color` …).
- Produces (Signaturen wie im Schnittstellenvertrag, keine Abweichung):
- `ColorValue::check(string): ?string`, `ColorValue::relative(array): array|string`, `ColorValue::TYPES_NOTE`.
- `ColorBook`: `fromDivi`, `data`, `rev`, `entry`, `label`, `isCustomizer`, `find`, `with`, `referencing`, `cycle`, `changedSince`, `newId`, `now`, `CUSTOMIZER_IDS`. Die Testdatei `ColorBookTest` liefert die Hilfen `ColorBookTest::stored()` (Form von `get_global_colors()`: zwei Hauptfarben, „Holz dunkel“, eine relative Farbe „Holz hell“, zwei Farben mit Label „Doppelt“) und `ColorBookTest::ref($id, $settings)`; spätere Tests (`ColorAreaTest`, `ColorRestorePlannerTest`) dürfen sie benutzen.
- `ColorDiff::between(ColorBook, ColorBook): list<array{id, name, action, fields?}>`, `ColorDiff::summary(array): string`.
**Regeln dieses Tasks (alle durch Tests belegt):**
- `ColorValue::check()` prüft nur Klartext-Werte (V5): Hex mit 3, 4, 6 oder 8 Stellen, `rgb()`/`rgba()`/`hsl()`/`hsla()` (nur Ziffern, Buchstaben, `. % + - / ,` und Leerraum, mindestens eine Ziffer, höchstens 100 Zeichen – nichts, womit man aus dem Wert ausbrechen könnte), ein Schlüsselwort aus 3–20 Buchstaben. Leerraum am Rand, `$variable(`, `{{` und alles andere gelten als ungültig; der Aufrufer löst Platzhalter vorher auf und trimmt Eingaben. `relative()` erlaubt nur `hue` (−360…360), `saturation`, `lightness`, `opacity` (je −100…100), nur int/float (kein Text, kein Bool, kein NaN), liefert sie in fester Reihenfolge und macht ganze Gleitkommazahlen zu `int`.
- `ColorBook` kennt die sechs Schlüssel `color, folder, label, lastUpdated, status, usedInPosts`; fehlende werden aufgefüllt (`''`, `''`, `''`, `''`, `'active'`, `[]`), fremde fallen weg. Eingabe als Array **oder** Objekt (auch verschachtelt `stdClass`) – `get_global_colors()` und ein Snapshot haben dieselbe Form. `lastUpdated` der Hauptfarben (ID in `CUSTOMIZER_IDS` oder `folder: customizer`) ist immer `''` (V3), auch nach `with()`.
- `find()`: ID, dann Alias (`primary` …), dann Optionsname (`accent_color` …), dann Label (getrimmt, ohne Beachtung der Groß-/Kleinschreibung); mehrere Treffer → `InvalidArgumentException` „Name der globalen Farbe "X" ist mehrdeutig; bitte die ID angeben: a, b.“ (Text wie `DesignSystem::byLabel`).
- `cycle()` folgt je Farbe der Kette ihrer Verweise (`VariableRef::typeOf()` = `color`, Ziel aus dem Payload) und meldet die erste Kette mit Schleife (`[a, b, c, b]`, Selbstverweis `[a, a]`) oder mit mehr als 10 Verweisen (12 IDs bei 11 Verweisen; Divi löst mit `$depth >= 10` nur bis zum 10. Verweis auf). Ein Verweis auf eine unbekannte Farbe beendet die Kette ohne Fund – das prüft `ColorArea` (Task 6).
- `ColorDiff`: Verglichen werden `color`, `folder`, `label`, `status` (nicht `lastUpdated`, `usedInPosts`). Statuswechsel nach `inactive` = `deactivated`, nach `active` = `activated`; jeder andere Statuswechsel (`temporary`) = `changed` mit `status` in `fields`. `fields` bei `deactivated`/`activated` nennt nur weitere Änderungen. Fehlt eine Farbe nachher, ist das `removed` (nur ein Restore mit Ersetzen kann das).
#### Task 3a: `ColorValue` – Farbwerte und relative Einstellungen prüfen
- [ ] **Step 3a.1: Failing Test `ColorValueTest` schreiben**

---
### Task 4: `VariableValue`, `VariableBook`, `VariableDiff` – reiner Variablenbestand (V1, V6, V7)
**Files:**
- Create: `src/Integrations/Divi/Design/VariableValue.php`, `VariableBook.php`, `VariableDiff.php`
- Test: `tests/Unit/Integrations/Divi/Design/VariableValueTest.php`, `VariableBookTest.php`, `VariableDiffTest.php` (alle neu, erben von `PHPUnit\Framework\TestCase`)
**Interfaces:**
- Consumes: `LIT\MCP\Abilities\Rev::of()`, `ColorBook::now()` (aus Task 3, für gleiches Zeitstempelformat).
- Produces (Signaturen wie im Schnittstellenvertrag, keine Abweichung):
- `VariableValue::TYPES`, `VariableValue::check(string $type, string $value): ?string`.
- `VariableBook`: `fromDivi`, `data`, `rev`, `entry`, `typeOf`, `find`, `with`, `nextOrder`, `restoredFrom`, `onlyHere`, `newId`, `now`. Die Testdatei `VariableBookTest` liefert `VariableBookTest::stored()` (Speicherform: `numbers` ×3 darunter eine archivierte, `strings` ×2 mit einem Label, das auch in `numbers` vorkommt, `fonts`, `gradients`), `::fromGetter()` (Form von `get_global_variables()` mit `stdClass`-Gruppen, `allowedActions`, Customizer-Schriften und Gruppe `colors`) und `::variable(...)`; spätere Tests (`VariableAreaTest`, `VariableRestorePlannerTest`) dürfen sie benutzen.
- `VariableDiff::between(VariableBook, VariableBook)`, `VariableDiff::summary(array)`.
**Regeln dieses Tasks (alle durch Tests belegt):**
- `VariableValue::check()` setzt V6 um; `gradients` und alles außerhalb von `TYPES` liefert „Typ "…" ist nicht erlaubt; erlaubt: numbers, strings, images, links, fonts.“ (das Durchreichen von `gradients` ist Sache von `VariableBook`). Leerer Wert → „Wert fehlt (Typ "…").“; ungültiges UTF-8 wird abgelehnt. Links: `http(s)://…`, `/…` (auch `/kontakt/#formular`), `mailto:…`, `tel:…`, keine Leerzeichen, `<`, `>`, `"`. Bilder: nur Ziffern oder `http(s)://`-URL.
- `VariableBook` kennt die sieben Schlüssel `id, label, value, order, status, lastUpdated, variableType` (feste Reihenfolge, fremde Schlüssel wie `allowedActions` fallen weg); `id` und `variableType` stammen aus Schlüssel und Gruppe, nicht aus dem Eintrag; `order: null` (so archiviert der Builder) wird `''`. Typen in fester Reihenfolge `numbers, strings, images, links, fonts, gradients`; `colors`, unbekannte Typen, leere Gruppen und Einträge ohne `gvid-`-Präfix (Customizer-Schriften `--et_global_*_font`) entfallen. `gradients` bleibt unverändert erhalten. `with()` wirft `InvalidArgumentException` („Unbekannter Variablentyp "colors".“) für einen Typ, den Divi nicht speichert.
- `restoredFrom($snapshot)` (V1b): alle Einträge des Snapshots, dazu jeder Eintrag, den es nur im aktuellen Bestand gibt, mit `status: archived` und `order: ''` – jede aktuelle ID bleibt erhalten, wie `validate_global_variable_ids()` es verlangt. `onlyHere($snapshot)` nennt davon nur die bisher **aktiven** (für die Warnung im Probelauf).
- `VariableDiff`: Verglichen werden `label`, `value`, `order`, `status`. Statuswechsel nach `archived` = `archived`, von `archived` nach `active` = `activated`; dabei zählt `order` nicht (Archivieren leert sie) und `fields` nennt nur `label`/`value`. Ein Eintrag, der nachher fehlt, erzeugt keine Zeile (Variablen werden nie entfernt, V1).
#### Task 4a: `VariableValue` – Variablenwerte je Typ prüfen
- [ ] **Step 4a.1: Failing Test `VariableValueTest` schreiben**
Datei `tests/Unit/Integrations/Divi/Design/VariableValueTest.php`. Datenanbieter für gültige und ungültige Werte je Typ, Grenzen inklusive, `gradients` und `colors` als nicht anlegbare Typen.

### Task 5: `ReferenceUsageQuery`, `PresetBook::referencing()` und `PresetBook::withVariableResolved()`
**Files:**
- Create: `src/Integrations/Divi/Design/ReferenceUsageQuery.php`
- Modify: `src/Integrations/Divi/Design/PresetBook.php` (Konstante `SETTINGS`, `referencing()`, `withVariableResolved()`)
- Test: `tests/Unit/Integrations/Divi/Design/ReferenceUsageQueryTest.php` (neu)
- Test: `tests/Unit/Integrations/Divi/Design/PresetBookTest.php` (ergänzt: `storedWithReferences()` und vier Tests)
**Interfaces:**
- Consumes: `Library\UsageQuery` (`ESCAPED_LETTER_REGEX`), `BlockTree\Parser::parse()`, `BlockTree\Container::children()`,
`BlockTree\Block::attrs()/isOpaque()/rawOpen()`, `BlockTree\MalformedMarkup`, `Compose\VariableRef::nameOf()/settingsOf()/serialize()`.
- Produces:
- `final class ReferenceUsageQuery implements UsageQuery` mit
`public function __construct(array $ids, private Parser $parser = new Parser())` (`list<string>` gcid-/gvid-IDs; leer →
`InvalidArgumentException`), `public const ESCAPED_HYPHEN_REGEX`, `public static function mentions(mixed $value, array $ids): bool`
(rekursiv: enthält ein String in `$value` eine der IDs). `matches()`: Rohinhalt nennt eine ID (auch Divi-4-Shortcodes) **oder** die
dekodierten Attribute irgendeines Blocks (auch in globalen Modulen, rekursiv über den ganzen Baum) nennen eine ID **oder** ein Block hat
unlesbare Attribute **oder** der Parser lehnt das Markup ab → `true` (fail closed).
- `PresetBook::referencing(string $id): array` → `list<array{id: string, name: string, scope: string}>` (`scope` = Modul- bzw.
Gruppenname wie in `PresetDiff`).
- `PresetBook::withVariableResolved(string $id, string $value, bool $affixes = false): self` – ganze Verweise
`$variable({"type":"content","value":{"name":"<id>",…}})$` in `attrs`/`styleAttrs`/`renderAttrs` → `$value`; mit `$affixes`
`before . $value . after` aus den Einstellungen des Verweises (Task 8 übergibt `$variableType === 'strings'`, V9). Eingebettete
Verweise bleiben stehen.
**Warum kein `NodeIndex`:** `NodeIndex::walk()` steigt nicht in opake Blöcke (globale Module) und nicht in Nicht-Divi-Blöcke ab; die
Fundstellensuche muss fail closed jeden Block sehen. `ReferenceUsageQuery` läuft deshalb selbst rekursiv über `Container::children()` des
geparsten `Document`. Ein `\u002d` (JSON-kodierter Bindestrich) nach `gcid`/`gvid` findet `LIKE` nicht – dafür das zweite `REGEXP`
(Muster wie `ModuleUsageQuery` für den Schrägstrich).

### Task 6: `ColorArea` und `lit/divi-colors-set`
**Files:**
- Create: `src/Integrations/Divi/Design/ColorArea.php`
- Create: `src/Integrations/Divi/Design/DiviColorsSetAbility.php`
- Test: `tests/Unit/Integrations/Divi/Design/ColorAreaTest.php` (neu, mit den Fixtures `stored()` und `adapter()`)
- Test: `tests/Unit/Integrations/Divi/Design/DiviColorsSetAbilityTest.php` (neu)
**Interfaces:**
- Consumes: `GlobalColorsAdapter::read()/save(array $entries, bool $replace)` (Task 2; in Tests per Mockery gemockt – die Klasse darf
darum nicht `final` sein, siehe ABWEICHUNGEN), `DesignRights::colors(DesignSystemWriter)` (Task 2), `DiviFeature::ColorWrite`
(Task 1), `ColorBook::fromDivi()/data()/rev()/entry()/label()/isCustomizer()/find()/with()/referencing()/cycle()/changedSince()/
newId(?Closure)/now()`, `ColorValue::check()/relative()`, `ColorDiff::between()/summary()` (Task 3), `ReferenceUsageQuery`,
`PresetBook::referencing()` (Task 5), `DesignChange::run()/inputProperties()/outputSchema()`, `DesignPlan`, `GlobalUsages::reportFor()`,
`UsageReport`, `DesignSystemWriter::presets()/canUseVisualBuilder()`, `VariableRef::serialize()`, `Errors`, `Annotations`.
- Produces:
- `final class ColorArea implements DesignArea { public function __construct(private GlobalColorsAdapter $colors) }` – `name()`
`'colors'`, `label()` `'Farben'`, `feature()` `DiviFeature::ColorWrite`; `write($raw, false)` speichert nur
`ColorBook::fromDivi($raw)->changedSince(<live gelesen>)` über `save($changed, false)` (nichts, wenn leer); `write($raw, true)` und
`restore($raw)` speichern den ganzen Bestand über `save($data, true)`; beide liefern den zurückgelesenen Bestand.
- `final class DiviColorsSetAbility implements Ability, RequiresDiviFeatures` mit
`__construct(DesignSystemWriter $writer, GlobalColorsAdapter $colors, DesignChange $change, GlobalUsages $usages, ?Closure $random = null)`
(Task 10 verdrahtet ohne `$random`); `public const MAX_ITEMS = 50`.
**Eingabe `items[]` von `lit/divi-colors-set`:** `id` (vorhandene Farbe: ID, Name, Alias `primary|secondary|heading|body|link` oder
Optionsname `accent_color …`, über `ColorBook::find()`), ohne `id` neue Farbe mit Pflichtfeldern `label` und `color`; `label` (1–100
Zeichen, frei – nicht schon Name, ID oder Alias einer anderen Farbe), `color` (V5), `relative` (nur mit Platzhalter, dann Pflicht),

- [ ] **Step 14: Tests laufen lassen – sie bestehen**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter 'DiviColorsSetAbilityTest|ColorAreaTest'`
Expected: PASS.
- [ ] **Step 15: Lint und Commit**
Run: `composer lint`
Expected: keine Meldungen.
```bash
git add src/Integrations/Divi/Design/DiviColorsSetAbility.php tests/Unit/Integrations/Divi/Design/DiviColorsSetAbilityTest.php
git commit -m "feat: lit/divi-colors-set löst {{color:…}} mit relative gegen den geplanten Bestand auf, lehnt Zyklen ab und warnt vor Verwendungen in Presets und relativen Farben" -m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"
```
- [ ] **Step 16: Gesamtlauf**
Run: `composer test && composer lint`
Expected: alle Tests grün, Lint sauber. (`DiviColorsSetAbility` ist noch nicht registriert; das folgt in Task 10.)
---
### Task 7: `VariableArea` und `lit/divi-variables-set`
**Files:**
- Create: `src/Integrations/Divi/Design/VariableArea.php`
- Create: `src/Integrations/Divi/Design/DiviVariablesSetAbility.php`
- Test: `tests/Unit/Integrations/Divi/Design/VariableAreaTest.php` (neu, mit den Fixtures `stored()` und `adapter()`)
- Test: `tests/Unit/Integrations/Divi/Design/DiviVariablesSetAbilityTest.php` (neu)
**Interfaces:**
- Consumes: `GlobalVariablesAdapter::read()/save(array $data, array $expected)/canManage()` (Task 2; in Tests gemockt, darum nicht
`final`), `DesignRights::variables(DesignSystemWriter, GlobalVariablesAdapter)` (Task 2), `DiviFeature::VariableWrite` (Task 1),
`VariableValue::TYPES/check()`, `VariableBook::fromDivi()/data()/rev()/entry()/typeOf()/find()/with()/nextOrder()/restoredFrom()/
newId(?Closure)/now()`, `VariableDiff::between()/summary()` (Task 4), `ReferenceUsageQuery`, `PresetBook::referencing()` (Task 5),
`DesignChange`, `DesignPlan`, `GlobalUsages::reportFor()`, `UsageReport`, `DesignSystemWriter::presets()/canUseVisualBuilder()`.
- Produces:
- `final class VariableArea implements DesignArea { public function __construct(private GlobalVariablesAdapter $variables) }` –
`name()` `'variables'`, `label()` `'Variablen'`, `feature()` `DiviFeature::VariableWrite`; `write($raw, $mayRemove)` =
`save(VariableBook::fromDivi($raw)->data(), <live gelesen>)` (`$mayRemove` ohne Bedeutung: es wird nie entfernt, V1);
`restore($raw)` = `save(<live>->restoredFrom(<$raw>)->data(), <live>)` – auch beim Rollback der Pipeline bleiben so alle IDs erhalten.
- `final class DiviVariablesSetAbility implements Ability, RequiresDiviFeatures` mit
`__construct(DesignSystemWriter $writer, GlobalVariablesAdapter $variables, DesignChange $change, GlobalUsages $usages, ?Closure $random = null)`;
`public const MAX_ITEMS = 50`.
**Eingabe `items[]` von `lit/divi-variables-set`:** `id` (vorhandene Variable: ID oder Name über `VariableBook::find()`, mit `type`
eingeschränkt), ohne `id` neue Variable mit Pflichtfeldern `type` (`VariableValue::TYPES`), `label` und `value`; `label` (1–100 Zeichen,
frei über alle Typen), `value` (`VariableValue::check()`), `status` (`active|archived`). Archivieren setzt `order` auf `''`, Aktivieren hängt
die Variable mit `nextOrder()` hinten an; eine neue aktive Variable bekommt `nextOrder()`. Aktive Variablen brauchen einen Wert. Der Typ
einer vorhandenen Variable bleibt; Variablen vom Typ `gradients` (und anderen nicht anlegbaren Typen) lehnt das Tool ab. Kein `delete` (V1).

---
### Task 8: `DetachTarget`, Variablen-Detach (`VariableDetachRewrite`, `lit/divi-design-detach` mit `variable`)
**Files:**
- Create: `src/Integrations/Divi/Design/DetachTarget.php`, `src/Integrations/Divi/Design/VariableDetachRewrite.php`
- Test: `tests/Unit/Integrations/Divi/Design/DetachTargetTest.php`, `tests/Unit/Integrations/Divi/Design/VariableDetachRewriteTest.php`
- Modify: `src/Integrations/Divi/Design/DiviDesignDetachAbility.php`, `src/Integrations/Divi/Design/DetachRewrite.php` (nur `mentions()` öffentlich), `src/Integrations/Divi/DiviIntegration.php` (nur der Konstruktoraufruf des Detach-Tools)
- Modify (Tests): `tests/Unit/Integrations/Divi/Design/DiviDesignDetachAbilityTest.php`, `tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php` (ein `inputCases()`-Fall), `tests/Integration/divi-presets-assign-smoke.sh` (Erwartung für eine unbekannte Variable)
**Interfaces:**
- Consumes (Schnittstellenvertrag, Tasks 1–5): `DiviFeature::VariableWrite`; `GlobalVariablesAdapter::read()`, `::canManage()` (über `DesignRights::variables()`); `DesignRights::variables(DesignSystemWriter, GlobalVariablesAdapter)`; `VariableBook::fromDivi()`, `->find(string $needle): ?array{type, id}` (wirft `InvalidArgumentException` bei mehrdeutigem Label), `->entry(string $type, string $id): ?array`; `new ReferenceUsageQuery(list<string> $ids)`; `PresetBook::referencing(string $id): list<array{id, name, scope}>`, `->withVariableResolved(string $id, string $value): self`. Vorhanden: `VariableRef::nameOf()/settingsOf()/contains()/serialize()` (`Compose/VariableRef.php`; `nameOf()` liefert den Namen nur für einen *ganzen* Verweis vom Typ `content` – Farbverweise `type: color` bleiben damit außen vor), `PageRewriter::preview()/apply()`, `TreeRewrite` (ruft `notes()` nur für geänderte Blöcke), `DesignChange::run()`, `PresetArea`, `PresetDiff`, `PageRewriteReport`, `PostIdsInput`, `DetachRewrite`.
- Produces:
- `final class DetachTarget { public function __construct(public readonly string $subject, public readonly ?array $postIds, public readonly UsageQuery $query, public readonly Closure $rewrite, public readonly ?Closure $presets, public readonly string $nestedIn, public readonly array $notes, public readonly string $doneHint); public function change(): string; public function finished(array $skipped, int $hidden): bool; }` – `$presets` ist `Closure(PresetBook): PresetBook` (der Preset-Schritt) oder `null`.
- `final class VariableDetachRewrite implements NodeRewrite { public function __construct(string $id, string $value, string $variableType); public static function replacement(string $reference, string $value, string $variableType): string; }`
- `DetachRewrite::mentions(Block $block, string $id): bool` wird `public static` (vorher `private`).
- **Neue Konstruktor-Signatur** `DiviDesignDetachAbility::__construct(DesignSystemWriter $writer, GlobalVariablesAdapter $variables, DesignChange $change, GlobalUsages $usages, PageRewriter $pages, ?Closure $unfiltered = null)`; `diviFeatures($input)` = bisherige Liste, mit `variable` zusätzlich `VariableWrite`.
Regeln (V9, R10, Spec §10):
- `variable` (Name oder ID, ohne Beachtung der Groß-/Kleinschreibung über `VariableBook::find()`) und `preset` schließen sich aus (`validation_failed` an `variable`). Eine `gcid-`-ID ist eine Farbe → `unsupported` mit Hinweis „nur deaktivieren (lit/divi-colors-set)“; eine unbekannte Variable → `not_found` mit demselben Hinweis (deckt auch Farb-Labels ab). Ob die Variable aktiv oder archiviert ist, spielt keine Rolle; die Variable selbst wird nicht geschrieben. Ein Wert, der kein String ist (Typ `gradients`, falls Divi ihn als Objekt speichert), → `unsupported`.
- Ersetzt wird jeder Attributwert, der *genau ein* Verweis `$variable({"type":"content","value":{"name":"<gvid>",…}})$` ist, durch den aktuellen Wert; bei `strings` mit `before`/`after` aus den Einstellungen des Verweises (`before . Wert . after`). Eingebettete Verweise bleiben; `notes()` meldet sie je geändertem Modul. Farbverweise, andere Variablen, dynamische Inhalte und Nicht-Divi-Blöcke bleiben unberührt. Globale Instanzen, deren Attribute die ID nennen, stehen in `skipped` (`concernsInstance()` wie `DetachRewrite`).
- Ohne `post_ids` und wenn `PresetBook::referencing()` Presets nennt, läuft der Preset-Schritt (`withVariableResolved()`) wie bei Gruppen-Presets zuerst, mit Snapshot `presets`, in **einem** `confirm_required` (pages + diff + design_rev). Rechte: `DesignRights::presets()` (der Preset-Schritt schreibt Presets) und `DesignRights::variables()`; `edit_post` je Live-Fundstelle prüft der `PageRewriter` (P8/P8a) bzw. der Plan des Preset-Schritts.
- Fertig-Hinweis: „Jetzt kann lit/divi-variables-set die Variable archivieren (status: archived).“ (wie `DELETE_HINT` nur ohne `post_ids`, ohne `skipped`, ohne verborgene Fundstellen und ohne `remaining`).
#### 8a – `DetachTarget` statt des Arrays (Refactor, Verhalten unverändert)
- [ ] **Step 1: Absicherung: bestehende Detach-Tests grün**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter '/DiviDesignDetachAbilityTest|DetachRewriteTest/'`
Expected: `OK (31 tests, …)` (26 + 5). Diese Tests bleiben in 8a unverändert.
- [ ] **Step 2: Failing Test `DetachTargetTest` schreiben**

- [ ] **Step 5: GREEN**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter DetachTargetTest`
Expected: `OK (2 tests, 5 assertions)`.
- [ ] **Step 6: `DiviDesignDetachAbility` auf `DetachTarget` umbauen**
`target()` wird `presetTarget(): DetachTarget|WP_Error`; `dryRun()`, `presetDryRun()`, `nestedPlan()`, `confirmed()` und `afterPresets()` nehmen das Wertobjekt; `finished()` und `notes()` der Ability entfallen (jetzt `DetachTarget::finished()` bzw. `$target->notes`). Der Preset-Schritt ist die Closure `$target->presets` (`withoutNestedRef($id)`), `null` ohne Verschachtelung oder mit `post_ids` – genau die bisherige Bedingung `nested`. Texte bleiben Wort für Wort gleich: `subject` = `<Scope-Label> „<Name>“`, `nestedIn` = `anderen Presets`. Der Rest der Datei (Kopf bis `execute()`, `firstPageError()`, `invalid()`) bleibt.

Ohne die Anpassung bricht `DiviIntegration::abilities()` (u. a. `DiviIntegrationTest`, `DiviToolFeaturesTest`). Nur der Konstruktoraufruf; alles Weitere der Verdrahtung bleibt Task 10.
`src/Integrations/Divi/DiviIntegration.php`:
*Import (nach `DiviDesignDetachAbility`)* – vorher:
```php
use LIT\MCP\Integrations\Divi\Design\DiviDesignDetachAbility;
```
nachher:
```php
use LIT\MCP\Integrations\Divi\Design\DiviDesignDetachAbility;
use LIT\MCP\Integrations\Divi\Design\GlobalVariablesAdapter;

*Konstruktoraufruf (Zeilen 275–281)* – vorher:

$this->designWriter,
$this->designChange(),
```
nachher:
```php
new DiviDesignDetachAbility(
$this->designWriter,
new GlobalVariablesAdapter(),

```
`tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php` (die Zeile in `EXPECTED` bleibt: ohne `variable` ändert sich nichts):
*`inputCases()`, vor `'library-list'` (Zeile 176)* – vorher:
```php
'library-list' => ['lit/library-list', [], ['library-read', 'roles']],
```
nachher:
```php
'design-detach of a variable' => [
'lit/divi-design-detach', ['variable' => 'Eckenradius'],

- [ ] **Step 19: GREEN, Gesamtlauf, Lint**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter '/DiviDesignDetachAbilityTest|DiviToolFeaturesTest|DiviIntegrationTest/'`
Expected: PASS (`DiviDesignDetachAbilityTest` 33 Tests, `DiviToolFeaturesTest` 35).
Run: `composer test && composer lint`
Expected: alle Tests grün, phpcs ohne Meldung.
- [ ] **Step 20: Commit**
Commit wie in den Global Constraints:

Integration (optional, Smoke-Anpassung): `cd /home/janniclas/Projekte/WordPress && timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-presets-assign-smoke.sh` → alle `pass`. Der Variablen-Detach gegen echtes Divi folgt im Smoke von Task 11.
---
### Task 9: `RestorePlanner` je Bereich – Restore für Farben und Variablen (V1b, V10)
**Files:**
- Create: `src/Integrations/Divi/Design/RestorePlanner.php`, `src/Integrations/Divi/Design/PresetRestorePlanner.php`, `src/Integrations/Divi/Design/ColorRestorePlanner.php`, `src/Integrations/Divi/Design/VariableRestorePlanner.php`
- Test: `tests/Unit/Integrations/Divi/Design/PresetRestorePlannerTest.php`, `tests/Unit/Integrations/Divi/Design/ColorRestorePlannerTest.php`, `tests/Unit/Integrations/Divi/Design/VariableRestorePlannerTest.php`
- Modify: `src/Integrations/Divi/Design/DiviDesignRestoreAbility.php`, `src/Integrations/Divi/DiviIntegration.php` (nur der Konstruktoraufruf des Restore-Tools)
- Modify (Tests): `tests/Unit/Integrations/Divi/Design/DiviDesignRestoreAbilityTest.php`, `tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php`
**Interfaces:**
- Consumes (Schnittstellenvertrag, Tasks 1–7): `DiviFeature::ColorWrite`, `::VariableWrite`; `DesignRights::colors()`, `::variables()`; `GlobalColorsAdapter`, `GlobalVariablesAdapter` (mockbar, ohne Konstruktorargumente); `ColorBook::fromDivi()/data()/entry()/label()`, `ColorDiff::between()/summary()`; `VariableBook::fromDivi()/data()/restoredFrom()/onlyHere()`, `VariableDiff::between()/summary()`; `new ColorArea(GlobalColorsAdapter)`, `new VariableArea(GlobalVariablesAdapter)`. Vorhanden: `DesignChange::run()`, `SnapshotStore::get()` (Eintrag mit `data`), `PresetArea`, `PresetBook`, `PresetDiff`, `DesignRights::presets()/markup()/unfilteredHtml()`, `FeatureSets::merge()`.
- Produces:
- `interface RestorePlanner { public function area(): string; public function designArea(): DesignArea; public function rights(): ?WP_Error; public function features(): array; public function plan(array $current, array $snapshot, string $snapshotId): DesignPlan|WP_Error; }` – `$snapshot` ist das Feld `data` des Snapshots.
- `PresetRestorePlanner::__construct(DesignSystemWriter $writer, ?Closure $unfiltered = null)`
- `ColorRestorePlanner::__construct(DesignSystemWriter $writer, GlobalColorsAdapter $colors)`
- `VariableRestorePlanner::__construct(DesignSystemWriter $writer, GlobalVariablesAdapter $variables)`
- **Neue Konstruktor-Signatur** `DiviDesignRestoreAbility::__construct(DesignChange $change, SnapshotStore $snapshots, RestorePlanner ...$planners)`; `diviFeatures($input)` = Fähigkeiten des Planers zum Bereich der `snapshot_id`, ohne gültige ID bzw. ohne Planer die Vereinigung aller Planer (fail closed; das liest auch `FeatureOverview` mit `[]`).
Regeln (V10, V1b, V4, Spec §5/§10):
- Bereich = erste Gruppe der Snapshot-ID. Rechte und Fähigkeiten sind die des Bereichs; ohne gültige ID prüft die Ability die Rechte aller Planer (fail closed). `unsupported` („Theme-Optionen folgen mit Etappe 4d.“) nur noch für `theme_options`.
- Presets: Code und Texte unverändert verschoben (Ersetzen des ganzen Bestands, `mayRemove`, Markup-Sperre).
- Farben: der Snapshot ersetzt alle gespeicherten Farben (`mayRemove: true` → `GlobalColorsAdapter::save(…, true)`). Farben, die es nur jetzt gibt, entfallen: der Planer hängt dafür Zeilen `action: removed` an den Diff (ColorDiff kennt keine Entfernung), nennt sie in `summary` („Entfernt: N.“) und in einer Warnung.
- Variablen: `VariableBook::restoredFrom()` – jede Variable des Snapshots kommt zurück, neuere bleiben **archiviert** erhalten (Divi lehnt fehlende `gvid-`-IDs ab), je eine Warnung aus `onlyHere()`; `mayRemove: false`.
#### 9a – `RestorePlanner` und `PresetRestorePlanner` (Refactor, Verhalten unverändert)
- [ ] **Step 1: Absicherung: bestehende Restore-Tests grün**
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter '/DiviDesignRestoreAbilityTest|DiviToolFeaturesTest/'`
Expected: `OK (39 tests, …)` (4 + 35 nach Task 8).
- [ ] **Step 2: Failing Test `PresetRestorePlannerTest` schreiben**

Expected: FAIL – `Error: Class "LIT\MCP\Integrations\Divi\Design\PresetRestorePlanner" not found`.

Der Planungscode ist die bisherige Closure aus `DiviDesignRestoreAbility::execute()` (Zeilen 125–147), die Konstante `MARKUP` (Zeilen 26–27) und `DesignRights::presets()` – unverändert verschoben.

- Consumes: `DiviColorsSetAbility(DesignSystemWriter, GlobalColorsAdapter, DesignChange, GlobalUsages, ?Closure $random = null)` und `DiviVariablesSetAbility(DesignSystemWriter, GlobalVariablesAdapter, DesignChange, GlobalUsages, ?Closure $random = null)` (Tasks 6/7); `GlobalColorsAdapter`/`GlobalVariablesAdapter` ohne Konstruktorargumente (Task 2).
- Produces: beide Tools in `DiviIntegration::abilities()`, **eine** Adapter-Instanz je Integration (Eigenschaften `$colorsAdapter`, `$variablesAdapter`). Die Konstruktoraufrufe von `lit/divi-design-detach` (Task 8, Step 18) und `lit/divi-design-restore` (Task 9) haben dort inline `new GlobalVariablesAdapter()`/`new GlobalColorsAdapter()` eingeführt; dieser Task ersetzt sie durch die geteilten Eigenschaften. Die Fähigkeiten-Zeilen von `lit/divi-design-detach`/`-restore` in `DiviToolFeaturesTest` haben die Tasks 8/9 bereits angepasst und bleiben unberührt.
- [ ] **Step 1: Tests zuerst – Namensliste und Fähigkeitentabelle**
`tests/Unit/Integrations/Divi/DiviIntegrationTest.php`, in `EXPECTED` nach `'lit/divi-design-detach',` ergänzen (die Tools stehen am Ende von `abilities()`):
```php
'lit/divi-colors-set',
'lit/divi-variables-set',
```
`tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php`, in `EXPECTED` unter dem Kommentar `// Design system (divi)` nach der Zeile `'lit/divi-design-detach' => [ … ],` ergänzen:
```php
'lit/divi-colors-set' => ['design-read', 'color-write'],
'lit/divi-variables-set' => ['design-read', 'variable-write'],
```
Und in der zweiten Tabelle der Datei (Zeile mit `'lit/divi-presets-set' => 'preset-write', 'lit/divi-presets-delete' => 'preset-write',`, die jedem schreibenden Tool seine Schreib-Fähigkeit zuordnet) ergänzen:
```php
'lit/divi-colors-set' => 'color-write', 'lit/divi-variables-set' => 'variable-write',
```
Run: `php -d memory_limit=512M vendor/bin/phpunit --filter '/DiviIntegrationTest|DiviToolFeaturesTest/'`
Expected: FAIL – `DiviIntegrationTest` (die Namensliste enthält die zwei Tools nicht) und `DiviToolFeaturesTest` (die Tabelle nennt Tools, die es nicht gibt).
- [ ] **Step 2: Imports, Eigenschaften und Konstruktor**
`src/Integrations/Divi/DiviIntegration.php` – Imports (alphabetisch in die vorhandene Reihe der `Design\`-Imports einsortieren; `GlobalColorsAdapter` und `GlobalVariablesAdapter` stehen nach Task 8/9 schon dort):
```php
use LIT\MCP\Integrations\Divi\Design\DiviColorsSetAbility;
use LIT\MCP\Integrations\Divi\Design\DiviVariablesSetAbility;
```
Eigenschaften neben `private DesignSystemWriter $designWriter;`:
```php
private GlobalColorsAdapter $colorsAdapter;
private GlobalVariablesAdapter $variablesAdapter;
```
Im Konstruktor nach `$this->designWriter = new DesignSystemWriter();`:
```php
$this->colorsAdapter = new GlobalColorsAdapter();
$this->variablesAdapter = new GlobalVariablesAdapter();
```
- [ ] **Step 3: Tools registrieren, geteilte Adapter verwenden**
In `abilities()` die beiden inline-`new` aus Task 8/9 ersetzen und die neuen Tools ans Ende der Liste hängen. Vorher (Restore, nach Task 9):
```php
new ColorRestorePlanner($this->designWriter, new GlobalColorsAdapter()),
new VariableRestorePlanner($this->designWriter, new GlobalVariablesAdapter())
```
nachher:
```php
new ColorRestorePlanner($this->designWriter, $this->colorsAdapter),
new VariableRestorePlanner($this->designWriter, $this->variablesAdapter)
```
Vorher (Detach, nach Task 8):
```php
$this->designWriter,
new GlobalVariablesAdapter(),
$this->designChange(),
```
nachher:
```php
$this->designWriter,
$this->variablesAdapter,
$this->designChange(),
```
Nach dem Eintrag `new DiviDesignDetachAbility( … ),` (letzter Eintrag der Liste) anfügen:
```php
new DiviColorsSetAbility(
$this->designWriter,
$this->colorsAdapter,
$this->designChange(),
$this->globalUsages()
),
new DiviVariablesSetAbility(
$this->designWriter,
$this->variablesAdapter,
$this->designChange(),
$this->globalUsages()
),
```
- [ ] **Step 4: 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>`, nicht `lit-<name>`), und den Text der Ability anpassen, nicht den Test.
- [ ] **Step 5: Die eine falsche Zeile im Guide berichtigen**
`docs/guides/divi-design-system.md` Zeile 128 behauptet, `variable` werde nicht unterstützt. Ersetzen:
Alt: `- Variablen: \`variable\` wird noch nicht unterstützt (\`unsupported\`; Variablen folgen mit Etappe 4c).`
Neu: `- Variablen: \`variable\` (Name oder ID) ersetzt jeden ganzen Verweis auf die Variable durch ihren aktuellen Wert, auch in Presets; danach lässt sie sich mit \`lit/divi-variables-set\` archivieren (löschen kann Divi sie nicht).`
Run: `grep -rn "folgen mit Etappe 4c\|Variablen folgen" src docs/guides`
Expected: keine Treffer. Die übrigen Guides (Farben/Variablen schreiben, Reihenfolge) folgen gesammelt mit 4e (Spec §14 Schritt 9); Treffer zu 4d (Theme-Optionen) bleiben.
- [ ] **Step 6: Commit**
```bash
git add src/Integrations/Divi/DiviIntegration.php tests/Unit/Integrations/Divi/DiviIntegrationTest.php \
tests/Unit/Integrations/Divi/Release/DiviToolFeaturesTest.php docs/guides/divi-design-system.md
git commit -m "feat: lit/divi-colors-set und lit/divi-variables-set in der Divi-Integration; je ein geteilter Farben- und Variablen-Adapter" -m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"
```
### Task 11: Smoke gegen echtes Divi, Formate-Nachtrag, Spec und Notizen
**Files:**
- Create: `tests/Integration/divi-colors-variables-smoke.sh`
- Modify: `docs/superpowers/notes/2026-09-28-etappe-4-divi-formate.md` (Nachtrag 5.15.1 für Farben/Variablen, direkt nach dem Nachtrag „Divi 5.15.1 (Etappe 4a …)“)
- Modify: `docs/superpowers/specs/2026-10-16-etappe-4-designsystem-design.md` (§7.2)
- Modify: `docs/superpowers/notes/2026-10-18-divi-faehigkeiten.md` (Abschnitt „Offen“)
**Interfaces:**
- Consumes: alle Tools aus den Tasks 6–9 über den OAuth-Endpunkt (`lit/divi-colors-set`, `lit/divi-variables-set`, `lit/divi-design-detach`, `lit/divi-design-restore`, `lit/divi-design-snapshots`) 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 4c gegen das echte Divi 5.15.1 prüft und alles, was es ändert, im EXIT-Trap wiederherstellt.
- [ ] **Step 1: Das Smoke-Skript anlegen**
Datei `tests/Integration/divi-colors-variables-smoke.sh`:
```bash
#!/usr/bin/env bash

# cd /home/janniclas/Projekte/WordPress && timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-colors-variables-smoke.sh
# Creates colors/variables named "LIT Smoke <run> …" and one draft page. The EXIT trap puts the options et_divi (colors,

- [ ] **Step 2: Syntax prüfen**
Run: `bash -n tests/Integration/divi-colors-variables-smoke.sh && (command -v shellcheck >/dev/null && shellcheck -x tests/Integration/divi-colors-variables-smoke.sh || true)`
Expected: keine Syntaxfehler; shellcheck (falls installiert) ohne Fehler der Stufe error (Warnungen zu `$`-Escapes in `wp eval`-Strings sind erwartet).
- [ ] **Step 3: Formate-Nachtrag 5.15.1 für Farben und Variablen**
In `docs/superpowers/notes/2026-09-28-etappe-4-divi-formate.md` direkt nach dem Abschnitt „Nachtrag Divi 5.15.1 (Etappe 4a, 2026-10-16)“ einfügen:
```markdown
## Nachtrag Divi 5.15.1 – Farben und Variablen (Etappe 4c, 2026-10-19)
Geprüft gegen den installierten Quelltext `includes/builder-5/server/Packages/GlobalData/GlobalData.php` (5.15.1):
- **Farben unverändert:** `set_global_colors(array $data, $already_sanitized = false): void` mischt mit `true` (`array_merge`), ersetzt mit `false` und bereinigt dann selbst; die fünf Hauptfarben gehen über `et_update_option()` in `et_divi` und werden aus den Daten entfernt; danach `remove_static_resources('all', 'all', true)`. `sanitize_global_colors_data(array $data): array` ist öffentlich und verlangt, dass `usedInPosts` ein Array ist.
- **`get_customizer_colors()` hat einen `static`-Cache ohne Reset.** Nach einer Änderung der Hauptfarbe liefert `get_global_colors()` im selben Request noch den alten Wert (`$_cached_data` wird zurückgesetzt, der `static` nicht). LIT MCP liest die fünf Hauptfarben deshalb für das Zurücklesen aus `et_divi` (`GlobalColorsAdapter::read()`).
- **Variablen: neue Signatur und Prüfungen.** `set_global_variables(array $data, ?array $expected_variables = null): ?WP_Error` kehrt weiterhin still zurück, wenn `edit_theme_options` oder `variables_manager` fehlt; sonst läuft es unter einer MySQL-Sperre (`GET_LOCK`), prüft optional den erwarteten Bestand (`global_variables_stale`, 409), verlangt, dass **jede gespeicherte `gvid-`-ID im neuen Bestand vorkommt** (`validate_global_variable_ids()` → `global_variable_ids_missing`, 400) und prüft geänderte Einträge (`validate_global_variable_changes()`: `status` `active`|`archived`, aktive Variablen mit nicht leerem `value`). **Folge: Variablen lassen sich über Divis Funktionen nicht löschen, nur archivieren** (Ruling V1 des Plans 4c).
- **Neuer Typ `gradients`** (`GLOBAL_VARIABLE_TYPES = numbers, strings, images, links, fonts, gradients`); `strings` und `gradients` behalten ihren Wert zeichengetreu. `get_global_variables()` liefert zusätzlich die leere Gruppe `colors`, wandelt Objekt-Gruppen in Arrays und fügt `allowedActions` und die Customizer-Schriften hinzu (jede Gruppe als `stdClass`); beim Zurückschreiben bleiben nur Speicherformat-Felder.
- **Archivierte Variablen:** `_sort_global_variable_snapshot()` behandelt `order` archivierter Variablen als `''`; der Builder setzt beim Archivieren `order: null`, das Sanitize macht daraus `''`.
```
- [ ] **Step 4: Spec §7.2 nachführen**
In `docs/superpowers/specs/2026-10-16-etappe-4-designsystem-design.md` die Zeilen mit `delete: true` und „Löschen nur unbenutzt …“ in §7.2 ersetzen:
Alt (Zeile `- \`items\`: { id? | name?, "type": … }`): `…, "status": "active"|"archived" }`, `delete: true` für echtes Löschen.`
Neu: `…, "status": "active"|"archived" }`. Echtes Löschen gibt es nicht: Divi 5.15.1 verweigert jeden Bestand, dem eine gespeicherte `gvid-`-ID fehlt (Plan 4c, Ruling V1).`
Alt (Zeile `- Löschen nur unbenutzt (G5; …) …`): `- Löschen nur unbenutzt (G5; Fundstellen auch in Presets und relativen Farben), sonst \`in_use\` mit Hinweis auf detach. „Archivieren“ geht immer (Divi-Verhalten).`
Neu: `- Archivieren geht immer (Divi-Verhalten); der Probelauf nennt Fundstellen in Seiten, Presets und Farben als Warnung, \`lit/divi-design-detach\` löst die Verweise vorher (§6.8). Ein Restore behält später angelegte Variablen archiviert.`
Run: `grep -n "delete: true\|Löschen nur unbenutzt" docs/superpowers/specs/2026-10-16-etappe-4-designsystem-design.md`
Expected: keine Treffer in §7.2 (§6.4 „Nur unbenutzte Presets“ bleibt unberührt).
- [ ] **Step 5: Offene Punkte der Divi-Fähigkeiten-Notiz nachführen**
In `docs/superpowers/notes/2026-10-18-divi-faehigkeiten.md` im Abschnitt „Offen“ den Punkt `DesignArea::feature() braucht … (Etappe 4c/4d).` ersetzen durch:
```markdown
- `DesignArea::feature()`: Farben (`color-write`) und Variablen (`variable-write`) haben seit Etappe 4c eigene Fähigkeiten; Theme-Optionen bekommen ihre mit 4d.
```
- [ ] **Step 6: Commit**
```bash
git add tests/Integration/divi-colors-variables-smoke.sh docs/superpowers/notes/2026-09-28-etappe-4-divi-formate.md \
docs/superpowers/specs/2026-10-16-etappe-4-designsystem-design.md docs/superpowers/notes/2026-10-18-divi-faehigkeiten.md
git commit -m "test: Smoke für Farben und Variablen gegen Divi 5.15.1; docs: Formate-Nachtrag 4c, Variablen nur archivieren (Spec §7.2)" -m "Co-Authored-By: Claude <Modellname> <noreply@anthropic.com>"
```
### Task 12: Gesamtverifikation und Abschluss
**Files:**
- 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 1–11.
- Produces: grüne Suite, grüne Smokes, Gesamtreview ohne offene wichtige Befunde, aktualisierter Stand.
- [ ] **Step 1: Suite und Lint**
Run: `composer test && composer lint`
Expected: alle Tests grün (Zahl größer als 2877), phpcs ohne Befund.
- [ ] **Step 2: Divi-Prüfung und Referenz**
Run (DDEV, Divi 5.15.1): `cd /home/janniclas/Projekte/WordPress && ddev exec wp --user=admin lit-mcp divi-check`
Expected: Exit-Code 0, alle Fähigkeiten nutzbar, `color-write` und `variable-write` in der Matrix als „freigegeben“ bzw. „automatisch“. Meldet die Prüfung `signature`-Probleme für die neuen Symbole, `fingerprints.json` mit `--update-reference` neu erzeugen (Task 2 beschreibt das) und erneut prüfen.
- [ ] **Step 3: Smokes**
Run, jeweils einzeln (jeder muss mit `ALL CHECKS PASSED` enden):
```bash
cd /home/janniclas/Projekte/WordPress
timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-colors-variables-smoke.sh
timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-presets-smoke.sh
timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-presets-assign-smoke.sh
timeout 900 ddev exec bash wp-content/plugins/WP-LIT-MCP/tests/Integration/divi-release-smoke.sh
```
Erwartet: viermal `ALL CHECKS PASSED`. Schlägt ein Schritt des neuen Smokes fehl, zuerst die Antwort der Ability lesen (`fail` druckt sie), die Ursache im Code beheben (nicht das Skript lockern) und mit einem eigenen Commit nachziehen.
- [ ] **Step 4: Gesamtreview (zwei unabhängige Opus-Reviews parallel)**
Dispatch (zwei Subagents, Modell Opus, je mit dem Diff `git diff 63389f3..HEAD` und den Plan-Rulings V1–V10):
1. Fachreview: Korrektheit gegen Plan und Spec, Sicherheit (Werteprüfung, Rechte, `variables_manager`, Fundstellen-Rechte P8/P8a, Rollback, Snapshot-Größe), Verhalten der Randfälle (Hauptfarben, Zyklen, archivierte Variablen, Restore mit später angelegten Variablen).
2. `anthropic-skills:clean-code-review` über die neuen und geänderten Klassen (Quick-Modus), mit der Bitte, die vorgemerkten Punkte (`PresetStack`, `PageRewriter` aufteilen, gemeinsame Validierungshelfer der Abilities) nur zu erwähnen, nicht zu verlangen.
Wichtige und größere Befunde in einer Fix-Welle (Sonnet) beheben, danach Re-Review durch Opus; kleinere Befunde in die Ledger-Notiz der offenen Folgearbeit.
- [ ] **Step 5: Memory nachführen**
`etappe-4-stand.md` aktualisieren: 4c fertig (Commit-Hash, Testzahl, Datum), nächster Schritt „Plan 4d: Theme-Optionen und Schriften“ (`DesignArea::feature()` für `theme_options` braucht eine eigene Fähigkeit); aus 4c offen gelassene Punkte (aus dem Review) anhängen; Hinweis auf V1 (Variablen nur archivieren).
- [ ] **Step 6: Abschluss**
`git status` sauber; nichts pushen oder mergen ohne Auftrag. Dem Nutzer berichten: Testzahl, Smoke-Ergebnis, Befunde und Rulings (insbesondere V1), und fragen, ob der Branch gemergt/gepusht werden soll.
---
## Anhang: Abweichungen der Task-Autoren vom Schnittstellenvertrag (geprüft, im Plan berücksichtigt)
Die Autoren haben jeden Task in einer Kopie des Repos ausgeführt. Die folgenden Punkte weichen vom Vertrag ab oder verlangen Absprachen zwischen Tasks; wo der Vertrag oben schon angepasst ist, steht es dort. Verbindlich bleibt der Taskinhalt.
### Tasks 1-2
- **A1 Task 1 ohne eigenen Commit.** Global Constraints verlangen `composer test` grün nach jedem Task. Mit den zwei neuen Fällen allein schlägt `DiviFeatureAssignmentTest::testEveryFeatureIsServedByAtLeastOneRequirement` fehl (jede Fähigkeit braucht eine Manifest-Anforderung; die kommen erst mit den Adaptern) – per Probelauf bestätigt, sonst bricht nichts. Den Test aufzuweichen kommt nicht in Frage; darum committet Task 2 (Step 13) die Dateien beider Tasks zusammen. Alternative: Task 1 und 2 zu einem Task zusammenlegen.
- **A2 Adapter nicht `final`.** Der Schnittstellenvertrag schreibt „final class … implements DiviAdapter“. Das Repo hat kein bypass-finals; Mockery kann finale Klassen nicht ersetzen. `DesignRightsTest` (Task 2) und die Bereiche/Tools der Tasks 6/7/9 müssen die Adapter aber ersetzen (Divi fehlt in Unit-Tests). Die beiden Adapter folgen deshalb `DesignSystemReader`/`DesignSystemWriter` („Not final so … can be tested with a mock“). Namen und Signaturen bleiben wie im Vertrag.
- **A3 `save()` der Farben: „wirft, wenn Divi nichts speichert“ konkretisiert.** `set_global_colors()` ist `void` und meldet nichts. Der Adapter bereinigt deshalb in beiden Wegen vorher selbst mit `sanitize_global_colors_data()` und wirft, wenn dabei ein Eintrag wegfällt (leeres `color`, ID ohne `gcid-`); beim Ersetzen (`$replace = true`) bekommt `set_global_colors($clean, false)` die schon bereinigten Daten (Divi bereinigt erneut, idempotent). Was Divi danach still anders speichert, fängt erst `verify()` beim Zurücklesen (Task 6).
- **A4 Hauptfarben-Zuordnung doppelt.** `GlobalColorsAdapter` braucht die Abbildung ID → Option in `et_divi` schon in Task 2, `ColorBook::CUSTOMIZER_IDS` entsteht erst in Task 3. Der Adapter hält sie als `private const CUSTOMIZER`. Empfehlung für Task 3: `ColorBook::CUSTOMIZER_IDS` mit denselben Werten anlegen und in Task 3 einen Test ergänzen, der beide gleich hält – oder den Adapter in Task 3 auf `ColorBook::CUSTOMIZER_IDS` umstellen (ColorBook ist reines PHP, eine Konstante daraus berührt Divi nicht).
- **A5 Lese-Aufrufe nur mit der Schreib-Fähigkeit getaggt.** `get_global_colors`/`get_global_variables` stehen in den neuen Manifesten nur mit `color-write`/`variable-write` (Vorgabe des Manifests), nicht wie `GlobalPreset::get_data` im Writer zusätzlich mit `design-read`: das Designsystem-Tool liest weiter über `DesignSystemReader`, dessen Einträge `design-read`/`page-read` tragen. Ein Bruch dieser Aufrufe sperrt so Lesen (über den Reader) und Schreiben (über die Adapter) – wie gewünscht.
- **A6 `save()` prüft zusätzlich das Freigabe-Gate** (`ReleaseGate::assertFeature()` der eigenen Fähigkeit, wie `DesignSystemWriter::savePresets()`), obwohl `DesignChange::run()` das für `DesignArea::feature()` schon tut – doppelte Absicherung für Aufrufer außerhalb der Pipeline (Restore-Planer, Detach). Im Vertrag nicht genannt, ändert keine Signatur.
### Tasks 3-4
Keine Signatur des Schnittstellenvertrags ist geändert; die folgenden Punkte sind Auslegungen und Ergänzungen, die der Plan-Gesamtreview kennen muss. Der gesamte Code dieser zwei Tasks wurde in einer Kopie des Repos (Scratchpad `work/`, nur `src/` und `tests/` der neuen Dateien) geschrieben und ausgeführt: alle sechs Testklassen grün (121 Tests), `phpcs` ohne Meldung, die Gesamtsuite grün (2998 Tests, davon 2877 bestehende).
1. **`rev()` ist nicht sha1.** Der Vertrag nennt „sha1 über kanonisches JSON“; `PresetBook::rev()` (maßgebliches Vorbild laut Auftrag) benutzt `Rev::of()` = erste 12 Hex-Zeichen von sha256. Übernommen wurde das Verfahren von `PresetBook` (mit Präfix `colors`/`variables` + NUL, Schlüssel rekursiv sortiert, `JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES`). Die Signatur `rev(): string` bleibt; kein späterer Task hängt vom Hash-Verfahren ab.
2. **Farbverweis-Ziel ohne Änderung an `VariableRef`.** `VariableRef::nameOf()` liefert den Namen nur für `content`-Verweise; für `color`-Verweise gibt es keine öffentliche Lesefunktion (`settingsOf()` liefert nur die Einstellungen). `ColorBook::targetOf()` (privat, 6 Zeilen) nutzt `VariableRef::typeOf()` + `MARKER`/`END` + `json_decode`. Kleinste saubere Alternative, falls gewünscht: `VariableRef::colorNameOf(string): ?string` als Zwilling von `nameOf()` und `targetOf()` entfällt; für den Plan nicht nötig.
3. **`ColorDiff` kennt zusätzlich die Aktion `removed`** (Vertrag: `added|changed|deactivated|activated`). Ein Restore mit Ersetzen (V4: `set_global_colors($data, false)`) löscht Farben, die nach dem Snapshot entstanden; ohne `removed` fehlte diese Zeile im Probelauf. Task 9 (`ColorRestorePlanner`) kann stattdessen jüngere Farben als `inactive` behalten (wie V1b bei Variablen) – dann kommt `removed` nie vor, ist aber harmlos. Zusammenfassungstext dafür: „n gelöscht“. Außerdem: ein Wechsel nach `temporary` (oder andere Statuswerte) ist `changed` mit `status` in `fields`; `deactivated`/`activated` tragen `fields` nur für weitere Änderungen.
4. **`VariableBook::onlyHere()`** nennt nur aktive Einträge, die dem Snapshot fehlen (Vertrag: „Einträge, die `restoredFrom()` archiviert hätte“ – bereits archivierte archiviert `restoredFrom()` nicht neu, sie bekommen lediglich `order: ''`).
5. **`VariableDiff`** erzeugt für Einträge, die nachher fehlen, keine Zeile (V1: Variablen verschwinden nie); archivierte/aktivierte Zeilen ignorieren `order`.
6. **Beim Einlesen fallen Daten weg, die Divi selbst verwirft oder die das Format nicht kennt:** `VariableBook::fromDivi` ignoriert Einträge ohne `gvid-`-Präfix (Divis `sanitize_global_variables_data` verwirft sie beim Schreiben ebenfalls; das deckt zugleich die Customizer-Schriften ab), unbekannte Typen und fremde Eintragsschlüssel; `ColorBook::fromDivi` behält nur die sechs Schlüssel aus Formate §1 (Divis `sanitize_global_colors_data` würde beliebige Zusatzschlüssel mitschreiben – ein Snapshot gäbe sie nicht zurück). `ColorBook` setzt `lastUpdated` für jede Farbe mit `folder: customizer` auf `''`, nicht nur für die fünf Standard-IDs.
7. **Strenge der Werteprüfung (V5/V6) ist eine Auslegung:** `ColorValue::check()` trimmt nicht (Leerraum am Rand = ungültig; der Aufrufer trimmt vorher) und prüft Schlüsselwörter nicht gegen die CSS-Liste (jedes Wort aus 3–20 Buchstaben, Divi prüft ebenfalls nichts); `VariableValue` erlaubt bei Links auch `//host/pfad` (fällt unter „`/`-URL“). Divis `sanitize_text_field` kann bei `numbers`/`fonts`/`images` Zeichenfolgen wie `%ab` (Prozent plus zwei Hex-Zeichen) entfernen – das fängt das Zurücklesen (`verify`, Task 6/7), nicht die Vorabprüfung.
8. **Tiefengrenze:** „Tiefe > 10“ = mehr als 10 Verweise hintereinander (11 Verweise = 12 IDs in der Kette). Das entspricht `GlobalData::resolve_global_color_variable()` (`$depth >= 10` bricht ab; der 11. Verweis bliebe unaufgelöst). Der Vertrag lässt offen, ob Tiefe Verweise oder Farben zählt; die Tests (`testCycleStopsAtMoreThanTenReferences`) halten die Auslegung fest.
9. **`VariableBook::now()` ruft `ColorBook::now()` auf** (ein Zeitstempel-Format); Task 4 hängt dadurch von Task 3 ab. `newId()` ist in beiden Büchern getrennt (je 6 Zeilen), um keine dritte öffentliche Hilfsklasse außerhalb des Vertrags einzuführen.
10. **Test-Hilfen als öffentliche statische Methoden** (`ColorBookTest::stored()/ref()`, `VariableBookTest::stored()/fromGetter()/variable()`) – dasselbe Muster wie `PresetBookTest::stored()`; Tasks 6, 7 und 9 sollen sie wiederverwenden statt eigene Bestände zu bauen.
### Tasks 5-7
1. **Adapter nicht `final` (Task 2).** Der Schnittstellenvertrag nennt `final class GlobalColorsAdapter … implements DiviAdapter`. Die
Tests der Tasks 6/7 mocken `GlobalColorsAdapter` und `GlobalVariablesAdapter` mit Mockery (wie `DesignSystemWriter`, dessen Docblock
„Not final so abilities can be tested with a mock“ sagt); Mockery kann finale Klassen nicht mocken. Beide Adapter müssen darum
`class … implements DiviAdapter` sein (mit demselben Docblock-Satz). Alternative wäre ein Interface je Adapter – mehr Code ohne Nutzen.
2. **`PresetBook::withVariableResolved()` bekommt einen optionalen dritten Parameter** `bool $affixes = false`. V9 verlangt bei `strings`
`before . Wert . after` **aus den Einstellungen des jeweiligen Verweises** – das kann ein einziger `$value` nicht ausdrücken, und
`PresetBook` kennt den Typ der Variablen nicht. Vertragskompatibel (Default); Task 8 ruft `withVariableResolved($id, $value,
$variableType === 'strings')` auf.
3. **`ReferenceUsageQuery` nutzt nicht `NodeIndex`**, sondern läuft rekursiv über `Container::children()` des geparsten `Document`:
`NodeIndex::walk()` steigt nicht in opake Blöcke (globale Module) und Nicht-Divi-Blöcke ab, die Suche muss aber jeden Block sehen.
Zusätzlich fail closed: ein Treffer im Rohinhalt (`str_contains`, deckt Divi-4-Shortcodes wie `background_color="gcid-…"` ab) und
Blöcke mit unlesbaren Attributen zählen. Neu öffentlich: `ESCAPED_HYPHEN_REGEX` (zweites `REGEXP` für `gcid\u002d…`, das `LIKE` nicht
findet) und `mentions()` (von `PresetBook::referencing()` mitbenutzt); der Konstruktor nimmt optional `Parser $parser = new Parser()`.
4. **Konstruktoren der Abilities (für Task 10):** `DiviColorsSetAbility(DesignSystemWriter $writer, GlobalColorsAdapter $colors,
DesignChange $change, GlobalUsages $usages, ?Closure $random = null)` und `DiviVariablesSetAbility(DesignSystemWriter $writer,
GlobalVariablesAdapter $variables, DesignChange $change, GlobalUsages $usages, ?Closure $random = null)`. Der `DesignSystemWriter` wird
für `DesignRights::colors()/variables()` und für `presets()` (Warnungen) gebraucht.
5. **`VariableArea::write()` liest `$expected` selbst**, unmittelbar vor `save()` (`DesignArea::write()` bekommt den Planungsbestand nicht).
Gleichwertig zu V7, weil `DesignChange` unter der Sperre gerade erst die `design_rev` dieses Bestands verglichen hat; Divis
Stale-Prüfung fängt nur noch Schreibzugriffe am Plugin vorbei.
6. **`VariableArea::restore()` wendet `restoredFrom()` selbst an** (idempotent, wenn der Restore-Planer aus Task 9 es schon getan hat). Ohne
das würde der Rollback der Pipeline nach einem durchgegangenen Schreiben mit anschließend fehlgeschlagenem `verify()` an Divis
`global_variable_ids_missing` scheitern (die neue ID wäre gespeichert, der Snapshot kennt sie nicht) → `partial` statt `rolled_back`.
7. **Zusätzliche Regeln, die V3/V5/Spec nicht ausdrücklich nennen:** Hauptfarben bekommen keinen `{{color:…}}`-Verweis (Divi speichert sie
als festen Wert in `et_divi`, ein `$variable(…)$` bräche den Customizer); `{{color:…}}` verlangt `relative` (V5 „**mit** relative“);
Namen neuer/umbenannter Farben bzw. Variablen müssen frei sein (nicht Name, ID oder Alias eines anderen Eintrags, sonst würden
`{{color:…}}`/`{{var:…}}` mehrdeutig – analog A5 bei Presets); Ordner `customizer` ist für neue Farben gesperrt.
8. **Risiko `VariableArea::verify()`:** Es vergleicht wie gefordert nur IDs, Status und „Wert nicht leer“. Tut Divi bei einer reinen
Wertänderung still nichts (fehlendes `variables_manager`), besteht `verify()`, und `differences()` meldet „bereinigt“. Abgefangen
wird das vorher durch `DesignRights::variables()` (V7); wer es enger will, vergleicht in `verify()` zusätzlich die Werte der
geänderten Einträge.
9. **Annahmen über die parallel geplanten Klassen, auf denen die Tests ruhen:** `ColorBook::fromDivi($book->data())` und
`VariableBook::fromDivi($book->data())` sind idempotent; `ColorDiff`/`VariableDiff` liefern in `name` das Label; `VariableBook::fromDivi()`
behält die Gruppe `gradients`; `$book->restoredFrom($book)` ergibt denselben Bestand; `ColorValue::check('kein Wert!')`,
`ColorValue::check('$variable(…)$')`, `ColorValue::relative(['farbe' => 10])` und `VariableValue::check('numbers', '1px;}')` melden
Fehler, `ColorValue::check('white')` nicht; `nextOrder('strings')` ist bei vorhandenem `order` `'1'` und archivierten `''` gleich `'2'`;
`ColorBook::cycle()` liefert eine Kette, die `gcid-sand000002` enthält. Weicht ein Task-3/4-Plan davon ab, sind nur Testerwartungen
anzupassen, nicht der Ablauf. (Geprüft: Task 5 gegen den echten Code; Tasks 6/7 mit einfachen Ersatzklassen für Tasks 1–4 nach dem
Vertrag in einer Kopie außerhalb des Repos – alle RED-/GREEN-Schritte verhalten sich wie beschrieben, die 312 Design-Tests bleiben grün,
phpcs ist sauber.)
10. **Neue IDs zwischen Probelauf und `confirm`:** Wie bei `lit/divi-presets-set` (`PresetBook::newId()`) wird beim `confirm` neu geplant,
eine neue Farbe/Variable bekommt also eine andere zufällige ID als im Probelauf-`diff`. Die `design_rev` bezieht sich auf den Bestand,
nicht auf den Plan, darum stört das die Bestätigung nicht; die Tests prüfen IDs deshalb nur per Muster.
### Tasks 8-9
- **Verdrahtung vorgezogen (Task 10):** Beide Tools bekommen neue Konstruktor-Signaturen; `DiviIntegration::abilities()` wird in `DiviIntegrationTest`, `DiviToolFeaturesTest`, `IntegrationRegistryTest` u. a. gebaut. Damit `composer test` nach Task 8 und 9 grün ist, ändern 8c/9a/9c die zwei Konstruktoraufrufe in `DiviIntegration` (Adapter inline per `new`) und die Zeilen von `lit/divi-design-detach`/`lit/divi-design-restore` in `DiviToolFeaturesTest`. Task 10 darf das nicht doppelt tun.
- **Adapter müssen mockbar sein:** Der Vertrag nennt `GlobalColorsAdapter` „final class“. Die Ability- und Planer-Tests mocken beide Adapter mit Mockery (wie `DesignSystemWriter`, „Not final so abilities can be tested with a mock“); Mockery kann finale Klassen nicht mocken. Annahme: beide Adapter sind nicht final und haben einen Konstruktor ohne Pflichtargumente.
- **`PresetBook::withVariableResolved(string $id, string $value)` kennt den Variablentyp nicht:** Verweise auf eine `strings`-Variable mit `before`/`after` *in Presets* verlören diese Texte, während Seiten sie behalten (V9). Vorschlag für Task 5: intern `VariableDetachRewrite::replacement($ref, $value, $type)` nutzen bzw. die Signatur um `string $variableType` erweitern. Task 8 ruft die Methode wie im Vertrag auf.
- **`ColorDiff` kennt kein `removed`:** Ein Farben-Restore ersetzt über `set_global_colors($data, false)` alle Farben (V4) und entfernt damit neuere Farben. `ColorRestorePlanner` ergänzt die `removed`-Zeilen selbst und filtert Zeilen von `between()` zu IDs, die der Snapshot nicht kennt. Sauberer wäre `removed` in `ColorDiff`/`summary()` (Task 3).
- **Eingebettete Verweise:** `TreeRewrite` ruft `notes()` nur für geänderte Blöcke. Ein Modul (oder eine Seite), das die Variable *nur* eingebettet nennt, bekommt keinen Hinweis und steht nicht in `pages`; `ReferenceUsageQuery` zählt die Seite aber weiter als Fundstelle (blockiert als Live-Seite ohne `edit_post`, P8a), und der Fertig-Hinweis kann erscheinen, obwohl eingebettete Verweise bleiben. Die Tool-Beschreibung sagt, dass sie stehen bleiben.
- **`VariableWrite` im Detach:** Der Detach schreibt keine Variablen, liest sie aber über `GlobalVariablesAdapter` und prüft `canManage()`. Ob dafür `VariableWrite` nötig ist, hängt am Manifest aus Task 2 (Fähigkeiten von `get_global_variables`/`et_pb_is_allowed`); gewählt ist der Zweig `variable` = bisherige Liste + `VariableWrite`.
- **Rechte bei ungültiger `snapshot_id`:** Ohne gültigen Bereich prüft die Restore-Ability die Rechte aller Planer (fail closed) – ein Konto ohne `variables_manager` bekommt dann `forbidden` statt `validation_failed`.
- **Variablen ohne Textwert:** Ist `value` einer Variablen kein String (z. B. `gradients`, falls Divi den Typ als Objekt speichert), antwortet der Detach mit `unsupported`; V6 sagt nur „unverändert durchgereicht“.
