Checkpoint: headless JSON architecture documented + cleanup (Stufe 1+2)

Restore point before Stufe 3 (central resolver-service refactoring).

Includes this session's work:
- Success Story (usecase) rebuild: new fields/tabs, UsecaseSerializer,
  thin List/Show renderers, MM relations, inline content elements.
- vitec_columns content block (two-column layout with per-item content)
  incl. unified header section; special-cased JSON resolution.
- Container per-column flex (items[].config align/justify) + gap on parent.
- Unified header section across CEs/plugins/containers; header fields in JSON.
- ISO-style architecture spec: Documentation/Headless-JSON-Architecture.md.
- Cleanup: removed local scratch + verified .bak backups.
- Fixes: B-6 (undefined thumbnail variable in Downloadcardcollection image
  resolver), B-7 (unsatisfiable legacy CType OR branch in Downloadcard/Datasheets).

Rollback: git reset --hard snapshot-2026-07-09-pre-stufe3

+# VITEC Headless JSON Architecture — Software Architecture and Interface Specification
+
+| | |
+|---|---|
+| **Document identifier** | EVO‑VITEC‑HL‑001 |
+| **Version** | 1.0 |
+| **Status** | Released |
+| **Date** | 2026‑07‑09 |
+| **Applies to** | `evomedien/vitec` on TYPO3 v14.3 (headless) |
+| **Owner** | evomedien — VITEC relaunch |
+
+This document is drafted in the style of, and adopts the terminology conventions of,
+ISO/IEC/IEEE 42010 (architecture description), ISO/IEC/IEEE 26514 (information for
+users) and ISO/IEC 25010 (product quality). The key words **shall**, **should** and
+**may** are to be interpreted as normative requirements, recommendations and
+permissions respectively.
+
+---
+
+## Foreword
+
+The VITEC web platform is a *headless* TYPO3 installation: the CMS does not render
+HTML pages, it emits JSON that is consumed by a separate React front end. This
+specification describes the architecture, the public JSON interface, and the
+engineering conventions that keep the JSON output **consistent** across all content
+types and **maintainable** across TYPO3 and extension upgrades.
+
+It supersedes, as the authoritative reference, the informal tutorial
+`Documentation/HeadlessIntegration.md`, which is retained as an informative how‑to.
+
+## Introduction
+
+The platform combines the generic headless page renderer (`friendsoftypo3/headless`)
+with three sources of content JSON:
+
+1. **Custom plugins** (product, use case/success story, market, solution, downloads,
+   datasheets, events, news) rendered by dedicated *UserFunc* classes;
+2. **Layout containers** (b13/container based column grids and a card carousel)
+   rendered by a *DataProcessor*;
+3. **Content Blocks** (`friendsoftypo3/content-blocks`) serialised automatically by
+   `nb-headless-content-blocks`.
+
+All three are unified under a single **content‑element envelope** so that the front
+end can consume every element with one predictable shape.
+
+---
+
+## 1  Scope
+
+### 1.1 In scope
+This document specifies:
+- the runtime environment and the software stack (Clause 5);
+- the JSON rendering pipeline and its layers (Clause 6);
+- the public JSON interface — envelope, payloads, structured data (Clause 7);
+- the catalogue of content types and their JSON keys (Clause 8);
+- the mandatory conventions for implementing and extending renderers (Clause 9);
+- maintainability and upgrade‑safety requirements (Clause 10);
+- conformance criteria (Clause 11).
+
+### 1.2 Out of scope
+Front‑end (React) implementation, hosting/deployment, the editorial (backend) TCA
+form design except where it determines JSON output, and non‑headless (Fluid) rendering
+paths.
+
+## 2  Normative references
+
+The following documents are referred to in the text. For dated references, only the
+edition cited applies.
+
+- ISO/IEC/IEEE 42010, *Software, systems and enterprise — Architecture description*
+- ISO/IEC 25010, *Systems and software Quality Requirements and Evaluation (SQuaRE) — Product quality model*
+- ISO/IEC/IEEE 26514, *Systems and software engineering — Design and development of information for users*
+- ISO 8601‑1, *Date and time — Representations for information interchange*
+- IETF RFC 8259, *The JavaScript Object Notation (JSON) Data Interchange Format*
+- IETF RFC 2119, *Key words for use in RFCs to indicate requirement levels*
+- schema.org vocabulary (informative), *https://schema.org*
+
+## 3  Terms and definitions
+
+**3.1 headless** — operating mode in which TYPO3 returns JSON instead of HTML;
+enabled per site by `headless: 1` and the headless Site Sets.
+
+**3.2 content element** — a `tt_content` record; the atomic unit of page content.
+
+**3.3 CType** — the content‑element type identifier stored in `tt_content.CType`
+(e.g. `vitec_productlist`, `news_pi1`, `vitec_cols_50_50`).
+
+**3.4 envelope** — the invariant outer JSON structure shared by every content element
+(Clause 7.2).
+
+**3.5 payload** — the domain‑specific JSON produced for one content element and placed
+inside the envelope (Clause 7.3).
+
+**3.6 renderer** — a *UserFunc* class under `Classes/UserFunc/` that produces a payload.
+
+**3.7 serializer** — a service class under `Classes/Service/` that converts a domain
+record into JSON, used by one or more renderers.
+
+**3.8 resolver / processor** — `ContentElementResolver` and `ContainerChildrenProcessor`;
+they normalise a raw `tt_content` row into an envelope and resolve nested elements.
+
+**3.9 container** — a b13/container CType that owns child content elements via
+`tx_container_parent` and emits them as `items`.
+
+**3.10 Content Block** — a declaratively defined content element
+(`friendsoftypo3/content-blocks`), serialised by `nb-headless-content-blocks`.
+
+## 4  Symbols and abbreviated terms

+
+## 5  Runtime environment (architecture context)
+
+### 5.1 Software stack
+| Component | Version | Role |
+|---|---|---|
+| TYPO3 CMS | ^14.3 | Core CMS |
+| PHP | 8.x (per TYPO3 14) | Runtime |
+| `friendsoftypo3/headless` | ^5.0@rc | Page‑to‑JSON renderer, `lib.contentElement` |
+| `friendsoftypo3/content-blocks` | ^2.4 | Declarative content elements |
+| `netzbewegung/nb-headless-content-blocks` | ^0.0.23 | Content Blocks → JSON |
+| `b13/container` | ^3.1 | Nested column containers |
+| `georgringer/news` | ^14.0 | News records and plugins |
+| `evomedien/vitec` | ^1.0 | This project’s custom extension |
+
+> **NOTE** `friendsoftypo3/headless` is pinned to a **release candidate** (`^5.0@rc`).
+> This is an upgrade‑sensitivity point; see 10.4.
+
+### 5.2 Site configuration
+The headless mode is activated in `config/sites/vitec/config.yaml`:
+
+```yaml
+base: /
+headless: 1
+frontendBase: ''
+dependencies:
+  - friendsoftypo3/headless
+  - friendsoftypo3/headless-mixed
+  - nb-headless-content-blocks/headless-content-blocks
+  - georgringer/news
+```
+
+The Site **Sets** listed under `dependencies` load, in order, the headless TypoScript
+base, the mixed‑mode overrides, the Content Blocks JSON integration and the News
+integration. The VITEC Set (`EXT:vitec/Configuration/Sets/Vitecset`) layers the custom
+definitions on top. The headless page response carries
+`Content-Type: application/json; charset=utf-8`. Slug routing is configured with route
+enhancers for products (`tx_vitec_domain_model_product.slug`) and news detail
+(`path_segment`).
+
+### 5.3 Architectural principles (rationale)
+- **P1 — One envelope.** Every content element, regardless of source, is exposed with
+  the same outer shape so the front end has a single rendering contract.
+- **P2 — Payload isolation.** Domain JSON is produced in PHP, fully decoupled from
+  TypoScript, so business logic is testable and versionable.
+- **P3 — Dual entry.** Each renderer works both as a top‑level plugin and as a nested
+  child of a container (Clause 9.3).
+- **P4 — Fail soft.** A failing element yields empty output, never a broken page
+  (Clause 9.5).
+
+---
+
+## 6  Rendering pipeline
+
+The JSON for one page is assembled top‑down through the following layers.
+
+```
+HTTP request (Accept: application/json, headless:1)
+      │
+      ▼
+[L1] Page renderer            friendsoftypo3/headless
+      │   builds { meta, content[], … , jsonLd }
+      ▼
+[L2] Content‑element envelope lib.contentElement / lib.contentElementWithHeader
+      │   per CType: id, type, colPos, appearance, content{header,…}
+      ▼
+[L3] Payload injection        USER cObj → Classes/UserFunc/*JsonRenderer::render
+      │   places domain JSON under content.<key>
+      ▼
+[L4] Containers               tt_content.vitec_cols_* = JSON
+      │   ContainerChildrenProcessor → items[].contentElements[]
+      ▼
+[L5] Normalisation & nesting  ContentElementResolver / PLUGIN_RENDERERS
+      ▼
+[L6] Structured data (JSON‑LD) PageJsonLdRenderer + StructuredDataService
+```
+
+### 6.1 L1 — Page renderer
+`friendsoftypo3/headless` converts the requested page into a JSON document containing
+page metadata, the ordered array of content elements, navigation and the JSON‑LD
+graph. VITEC does not replace this layer; it contributes elements to `content[]`
+(L2–L5) and the `jsonLd` field (L6).
+
+### 6.2 L2 — Content‑element envelope
+Each CType is bound to a headless library object:
+
+```typoscript
+tt_content.<ctype> < lib.contentElementWithHeader
+```
+
+`lib.contentElement` provides `id`, `type`, `colPos`, `categories`, `appearance`.
+`lib.contentElementWithHeader` additionally provides, under `content`, the standard
+header fields: `header`, `subheader`, `headerLayout`, `headerPosition`, `headerLink`
+(link resolved via typolink). **All VITEC plugins and all News CTypes inherit
+`lib.contentElementWithHeader`**, giving a uniform header section in both backend and
+JSON (see the companion header convention).
+
+### 6.3 L3 — Payload injection
+The domain payload is added as a `USER` content object under `content.fields.<key>`:
+
+```typoscript
+tt_content.vitec_productlist < lib.contentElementWithHeader
+tt_content.vitec_productlist {
+    fields {
+        content {
+            fields {
+                products = USER
+                products.userFunc = Evomedien\Vitec\UserFunc\ProductListJsonRenderer->render
+            }
+        }
+    }
+}
+```
+
+`render()` returns a JSON string that the headless JSON cObject embeds verbatim at
+`content.products`. The key is **plural for list plugins** and **singular for detail
+plugins** (Clause 9.6).
+
+### 6.4 L4 — Containers
+Column containers are defined as a self‑contained JSON object, not via
+`lib.contentElement`:
+
+```typoscript
+tt_content.vitec_cols_50_50 = JSON
+tt_content.vitec_cols_50_50.fields {
+    id … type … appearance … header … subheader …
+    gap = TEXT                       # tx_vitec_gap (whole‑grid gap)
+    items = JSON
+    items.dataProcessing.10 = Evomedien\Vitec\DataProcessing\ContainerChildrenProcessor
+}
+tt_content.vitec_cols_33_66     < tt_content.vitec_cols_50_50
+tt_content.vitec_container      < tt_content.vitec_cols_50_50   # single column, no gap
+tt_content.vitec_cards_carousel < tt_content.vitec_cols_50_50   # + carousel settings
+```
+
+> **RULE (normative)** Container CTypes **shall** be derived with the **copy**
+> operator `<`, never the reference operator `=<`. A `tt_content → tt_content`
+> reference is not recognised as an independent renderer by the headless content
+> mapper and silently falls back to raw output (see 10.5, and Annex B‑1).
+
+### 6.5 L5 — Normalisation and nested plugins
+`ContainerChildrenProcessor` queries children by `tx_container_parent`, groups them by
+`colPos` and emits, per column, a flex configuration plus the resolved children. Each
+child is normalised by the same envelope logic as `ContentElementResolver`. When a
+child is itself a VITEC plugin, it is resolved through the shared `PLUGIN_RENDERERS`
+map (Clause 7.4).
+
+### 6.6 L6 — Structured data (JSON‑LD)
+`PageJsonLdRenderer` (bound at `page…fields.jsonLd`) assembles a schema.org `@graph`
+via `StructuredDataService`, encoded with `JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE`.
+Node types and their triggers:
+
+| Node | Emitted when |
+|---|---|
+| `Organization` | every page (from site settings `seo.organization.*`) |
+| `WebSite` | only on the site root page |
+| `BreadcrumbList` | from the rootline (spacer/folder/recycler doktypes skipped) |
+| `NewsArticle` | on news‑detail page layouts (`pages.layout ∈ {13,14,15}`) |
+| `FAQPage` | when the page contains `vitec_faq` elements → `vitec_faq_items` collection |
+| `ExhibitionEvent` | from `vitec_eventlist` elements → `tx_vitec_domain_model_event` (windowed by the FlexForm `daysinadvance`) |
+| `Product`, `VideoObject` | via `ProductShowJsonRenderer` for product detail pages |
+
+FAQ and event nodes are collected from the respective tables; event image URLs are
+currently built with a hard‑coded `/fileadmin` prefix (see 10.3 / Annex B‑5).
+
+---
+
+## 7  JSON interface specification
+
+### 7.1 Encoding
+Output **shall** be RFC 8259 JSON, UTF‑8. Timestamps **shall** be Unix epoch seconds
+(integer); where ISO 8601 strings are required by schema.org they are produced inside
+the JSON‑LD layer.
+
+### 7.2 Content‑element envelope
+Every element in `content[]` conforms to:
+
+```jsonc
+{
+  "id": 123,                       // tt_content.uid
+  "type": "vitec_productlist",     // tt_content.CType
+  "colPos": 0,
+  "appearance": {
+    "layout": "0",
+    "frameClass": "default",
+    "spaceBefore": "",
+    "spaceAfter": ""
+  },
+  "content": {                     // present for lib.contentElement(WithHeader) CTypes
+    "header": "…", "subheader": "…",
+    "headerLayout": 2, "headerPosition": "", "headerLink": "https://…",
+    "<key>": { /* payload, Clause 7.3 */ }
+  }
+}
+```
+
+Elements produced by the resolver/processor (container children, inline story CEs) use
+a lean variant of the envelope:
+
+```jsonc
+{ "id": 456, "type": "text", "colPos": 211, "sorting": 1,
+  "appearance": { … }, "data": { /* non‑system fields */ } }
+```
+
+### 7.3 Payload keys
+| Kind | Key | Cardinality |
+|---|---|---|
+| List plugin | plural noun (`products`, `usecases`, `news → items`) | array |
+| Detail plugin | singular noun (`product`, `usecase`, `market`, `solution`) | object |
+| Container | `items` | array of `{config, contentElements}` |
+
+### 7.4 Container payload
+```jsonc
+{
+  "type": "vitec_cols_33_66",
+  "header": "…", "headerLayout": 2, "headerLink": "…",
+  "gap": "3",
+  "items": [
+    { "config": { "colPos": 251, "align": "stretch", "justify": "flex-start" },
+      "contentElements": [ /* normalised children, recursively */ ] },
+    { "config": { "colPos": 252, "align": "center", "justify": "space-between" },
+      "contentElements": [ … ] }
+  ]
+}
+```
+
+- `gap` is a **parent‑level** property (whole‑grid gap).
+- `align`/`justify` are **per‑column** and are read from the parent record
+  (`tx_vitec_col{N}_align/justify`); they therefore apply to **all** children of that
+  column. These container‑only fields **shall not** appear in a child’s `data`
+  (enforced by `CONTAINER_FIELDS` filtering).
+
+### 7.5 Success Story (use case) detail payload
+Produced by `UsecaseSerializer::serializeDetail()` — the reference implementation of
+the centralised pattern (Clause 9.2):
+
+```jsonc
+{
+  "uid": 1, "title": "…", "slug": "…", "subtitle": "…", "teaser": "…",
+  "cardImage": { "url": "…", "srcset": [ … ] }, "customerLogo": { … },
+  "hero": { "bgImage": …, "smallImage": …, "video": …,
+            "overlayColor": "#000", "overlayOpacity": 0.4,
+            "layout": "fullscreen", "textTheme": "light" },
+  "contentElements": [ /* inline CEs; the vitec_columns block is resolved specially */ ],
+  "related": { "show": true, "market": {…}, "solutions": [ … ], "products": [ … ],
+               "categories": [ … ] },
+  "seo": { "title": "…", "description": "…", "canonical": "…",
+           "robots": { "noIndex": false, "noFollow": false },
+           "openGraph": { "title": …, "description": …, "image": … },
+           "twitter":  { "title": …, "description": …, "image": … } },
+  "appearance": { "layoutVariant": "standard", "backgroundVariant": "none",
+                  "accentColor": "", "featured": false, … }
+}
+```
+
+SEO fields use fallback resolution (`seo_* → title/teaser`; `og_* → seo_* → title`;
+`twitter_* → og_*`; images `og_image → card_image → hero_bgimage`) so the front end
+always receives complete metadata.
+
+### 7.6 News payload
+Produced by `NewsJsonRenderer` under `content.news`:
+
+```jsonc
+{ "mode": "list",                  // "list" | "detail" | "error"
+  "items": [ { "uid": 1, "title": "…", "alternativeTitle": "…",
+               "pathSegment": "…", "detailUrl": "/news/…",
+               "canonicalUrl": "https://…", "teaser": "…", "bodytext": "…",
+               "datetime": 1625097600, "categories": [ … ], "media": [ … ] } ],
+  "settings": { "type": "news_pi1", "templateLayout": "1",
+                "templateLayoutLabel": "Compact List", "detailPid": 45, … } }
+```
+
+Ten News CTypes (`news_pi1`, `news_newsdetail`, `news_newsliststicky`, …) share one
+renderer; `news_newsdetail` yields `mode: "detail"` with a single `news` object.
+
+### 7.7 Content Blocks
+Content Blocks (`card`, `cta-banner`, `hero-section`, `intro-paragraph`, `video`,
+`faq`, `columns`) are serialised automatically by `nb-headless-content-blocks`: its
+`ContentBlocksJsonDataProcessor` converts the resolved record via `RecordToArray`,
+dropping system fields and recursing into files (→ URL + metadata), collections
+(e.g. `faq_items` → array of child records) and typolinks. The output uses the lean
+envelope (`{id, type, colPos, sorting, appearance, data}`). An optional per‑block
+`headless.php` hook may transform the array (none are currently defined). Fields carry
+the `vitec_` vendor prefix in storage. The **`vitec_columns`** block is
+the single exception: because it is authored **inline inside a Success Story record**,
+its collection items are resolved explicitly by `UsecaseSerializer::resolveColumnsElement()`
+into `{ header…, layout, columns: { left: [], right: [] } }`, with the collection
+storage table discovered from TCA (`foreign_table`) rather than hard‑coded.
+

+| CType | TS pattern | Renderer / Processor | Payload key | Kind |
+|---|---|---|---|---|

+
+## 9  Conventions (normative)
+
+These rules define the **single, uniform way** to implement and extend headless
+renderers. New code **shall** comply; existing code **should** be aligned when touched.
+
+### 9.1 Renderer class shape
+A payload renderer **shall**:
+1. reside in `Classes/UserFunc/` and be named `<Domain><Kind>JsonRenderer`;
+2. expose `#[AsAllowedCallable] public function render(string $content, array $conf): string`;
+3. expose `public function renderForRecord(array $row): string` for reuse by
+   containers/resolvers (Clause 9.3);
+4. return a JSON **string** (never an array/object).
+
+### 9.2 Serialisation ownership
+Domain‑to‑JSON conversion **should** live in a `Classes/Service/*Serializer` class, and
+the renderer **should** be a thin wrapper around it. `UsecaseSerializer` is the
+reference implementation. New list/detail pairs **shall** share one serializer.
+
+### 9.3 Dual‑entry pattern
+`render()` **shall** handle top‑level invocation: use `$this->cObj->data` when it is the
+plugin’s own row, otherwise perform page discovery (Clause 9.4). `renderForRecord()`
+**shall** accept an explicit `tt_content` row and be free of page/context assumptions,
+so it can be called by `ContainerChildrenProcessor` and `ContentElementResolver`.
+
+### 9.4 Page‑id discovery
+Renderers **shall** resolve the current page id in this order:
+```php
+$id = $GLOBALS['TYPO3_REQUEST']?->getAttribute('frontend.page.information')?->getId() ?? 0;
+if ($id <= 0) { $id = (int)($GLOBALS['TSFE']->id ?? 0); }   // fallback
+```
+Reliance on `$GLOBALS['TSFE']->id` alone is **prohibited** (it is frequently `null` in
+the JSON cObject context).
+
+### 9.5 Fail‑soft error handling
+The body of `renderForRecord()` **shall** be wrapped in
+`try { … } catch (\Throwable $e) { return ''; }`. Diagnostic output **may** be emitted
+only when a FlexForm `debug` flag is set. A failing element **shall not** propagate an
+exception to the page.
+
+### 9.6 Naming
+- List payload keys **shall** be plural; detail keys **shall** be singular.
+- JSON property names **shall** be `camelCase` for computed/composed fields; raw
+  passthrough fields in `data` retain their database names.
+
+### 9.7 Nested‑plugin registration
+A plugin that may appear inside a container **shall** be registered in the
+`PLUGIN_RENDERERS` map in **both** `ContentElementResolver` and
+`ContainerChildrenProcessor`, as `CType => [RendererClass::class, 'jsonKey']`.
+
+> **NOTE** The duplicated map is a known maintenance hazard (10.3). Until it is
+> centralised, both copies **shall** be kept in sync.
+
+### 9.8 Header section
+Every custom CE/plugin/container **shall** expose the standard header section (the core
+`headers` palette; Content Blocks use a `header_section` palette). See the companion
+"header convention". Header fields in JSON use the names `header`, `subheader`,
+`headerLayout`, `headerPosition`, `headerLink`.
+
+---
+
+## 10  Maintainability and upgrade‑safety (ISO 25010)
+
+This clause records the quality characteristics *maintainability* and *portability*
+and the concrete risks and rules that preserve them.
+
+### 10.1 Modularity — current state
+Strengths: uniform envelope, dual‑entry pattern, exception safety, a shared
+`PLUGIN_RENDERERS` map, and the `UsecaseSerializer` reference pattern.
+Weakness: **substantial duplication** across the inline renderers.
+
+### 10.2 Reusability — duplication register
+The following logic is duplicated across many renderers and **should** be extracted
+into shared services (target design in parentheses):
+
+| Duplicated logic | Occurrences | Target service |
+|---|---|---|
+| FAL image/`srcset` resolution | Product(List/Show), Market, Solution, Event, Datasheets | `FalImageResolver` |
+| FAL video resolution | Product, Usecase, hero | `FalImageResolver::video()` |
+| `sys_category` MM query | ≥ 9 renderers | `CategoryResolver` |
+| Custom MM (product↔download, …) | ≥ 5 renderers | `RelationResolver::resolveMany()` |
+| Download file‑by‑convention | 5 renderers | `ConventionFileResolver` |
+| `letterSequenceToRank()` sort helper | 5 renderers | static utility |
+| Page‑id discovery | all renderers | `PageIdResolver::resolve()` |
+
+> **RULE** When a shared resolver service exists, new renderers **shall** use it and
+> **shall not** re‑implement the logic inline.
+
+### 10.3 Analysability — single sources of truth
+- The `PLUGIN_RENDERERS` map exists in two files (10.2/9.7); it **should** be promoted
+  to one shared constant/class.
+- Table and field names are string literals scattered across renderers. New code
+  **shall** define table/field names as **class constants** (as `UsecaseSerializer`
+  and the processors already do) to localise upgrade impact.
+
+### 10.4 Portability — upgrade‑sensitivity points
+| Point | Risk | Mitigation |
+|---|---|---|
+| `friendsoftypo3/headless ^5.0@rc` | RC; `lib.contentElement(WithHeader)` shape may change | Pin exact RC; re‑verify envelope after any bump; keep payloads decoupled (P2) |
+| `nb-headless-content-blocks ^0.0.x` | pre‑1.0; CB→JSON shape and collection storage may change | `vitec_columns` resolution reads the table from TCA (`foreign_table`) — do **not** hard‑code CB tables |
+| `georgringer/news ^14` | 10 News CTypes hard‑mapped in `NewsJsonRenderer` | Keep the CType→layout map in one place; re‑verify on major news upgrade |
+| `b13/container ^3.1` | child linkage via `tx_container_parent`; page‑module grid required | Documented limitation: containers cannot be authored inside IRRE (Annex B‑2) |
+
+### 10.5 Modifiability — mandatory rules distilled
+1. Container CTypes **shall** use `<` (copy), never `=<` (reference) — see Annex B‑1.
+2. Table/field names **shall** be class constants, not inline literals.
+3. Renderers **shall** reuse shared resolver services once they exist.
+4. Magic numeric literals (e.g. a hard‑coded parent‑category uid) **shall** be replaced
+   by named constants or configuration.
+
+---
+
+## 11  Conformance
+
+An implementation conforms to this specification if, for every content type it
+exposes:
+- **C1** the output validates as RFC 8259 JSON and matches the envelope of 7.2;
+- **C2** the responsible renderer satisfies the class shape of 9.1 and the dual‑entry
+  pattern of 9.3;
+- **C3** page‑id discovery follows 9.4 and error handling follows 9.5;
+- **C4** payload keys follow 9.6 and the header section follows 9.8;
+- **C5** container derivation follows the `<`‑copy rule of 6.4/10.5(1);
+- **C6** any container‑nestable plugin is registered per 9.7.
+
+Deviations are recorded in Annex B and **shall** carry a remediation plan.
+

+
+## Annex A (normative) — Checklist: adding a new headless plugin
+
+1. **Model/TCA/SQL** — create the domain table and TCA; define table/field names as
+   constants.
+2. **Serializer** — add `Classes/Service/<Domain>Serializer` with `serializeListItem()`
+   and/or `serializeDetail()`; reuse existing resolver services.
+3. **Renderer** — add `Classes/UserFunc/<Domain><Kind>JsonRenderer` per 9.1, delegating
+   to the serializer; implement `render()` (9.3/9.4) and `renderForRecord()`.
+4. **TypoScript** — in `Configuration/Sets/Vitecset/setup.typoscript`:
+   `tt_content.<ctype> < lib.contentElementWithHeader` and
+   `content.fields.<key> = USER` + `.userFunc = …->render`.
+5. **Header section** — ensure the `headers` palette is present (9.8).
+6. **Nesting** — if the plugin may sit inside a container, register it in
+   `PLUGIN_RENDERERS` in **both** the resolver and the processor (9.7).
+7. **Deploy** — `vendor/bin/typo3 database:updateschema "*.add,*.change"` then
+   `vendor/bin/typo3 cache:flush`.
+8. **Verify** — fetch the page JSON; confirm envelope (C1), keys (C4) and nested output.
+
+---
+
+## Annex B (informative) — Nonconformity and technical‑debt register
+
+The following items were identified during architecture analysis. Items marked
+*(to verify)* were reported by static review and **shall** be confirmed before
+remediation.
+
+- **B‑1 — `=<` on Event/News CTypes.** `vitec_eventlist` and `news_pi1` use the
+  reference operator `=< lib.contentElementWithHeader`. Reference *to a `lib.*` object*
+  is used by headless itself and is generally safe; however, for consistency with
+  10.5(1) these are VERIFIED SAFE and left as-is (references to lib.* are idiomatic in headless; only tt_content-to-tt_content references are unsafe, and those are already `<` for containers).
+- **B‑2 — Containers cannot be authored inline (IRRE).** b13 container children live in
+  `tx_container_parent` and require the page‑module grid; they cannot be created inside
+  an inline field. This is a platform limitation, not a defect. The Success Story
+  "Columns" Content Block (`vitec_columns`) is the sanctioned inline alternative.
+- **B‑3 — Duplicated `PLUGIN_RENDERERS` map** in `ContentElementResolver` and
+  `ContainerChildrenProcessor` (9.7/10.3).
+- **B‑4 — Inline duplication** of image/category/MM/page‑id logic (10.2).
+- **B‑5 — Hard‑coded literals** — model/MM table names, a `/fileadmin` prefix for
+  event JSON‑LD image URLs (`PageJsonLdRenderer`), and at least one magic
+  parent‑category uid appear as inline literals across download/datasheet/structured‑data
+  code *(to verify and extract to constants)*. `COLPOS_TO_COLUMN` in
+  `ContainerChildrenProcessor` must be kept in sync with the container TCA colPos values.
+- **B‑6 — `DownloadcardcollectionJsonRenderer`**: two misplaced thumbnail output lines referenced an undefined variable in the image resolver. FIXED 2026-07-09 (removed; the PDF-thumbnail method is unaffected).
+- **B‑7 — v13→v14 `CType`/`list_type` compatibility branches** in some download/
+  datasheet renderers FIXED 2026-07-09: the unsatisfiable legacy OR branch was removed; the query now filters on the v14 CType only.
+
+---
+
+## Annex C (informative) — Related documents
+
+- `Documentation/HeadlessIntegration.md` — informal how‑to (superseded as the
+  authoritative reference by this document).
+- Header convention — the uniform header section across CEs, plugins and containers.
+- `Configuration/Sets/Vitecset/setup.typoscript` — the single TypoScript entry point.
