-description: Bump the Umbraco CMS version across all required files. Use when the user asks to bump, update, or set the version number — e.g., "bump version to 17.3.4", "set version to 18.0.0-rc", "update version". Accepts the target version as an argument.

-# Bump Version - Umbraco CMS
-
-Updates the Umbraco CMS version string across all files that track it.
-
-**Do NOT use AskUserQuestion if a version argument is provided. Only ask if `$ARGUMENTS` is empty or cannot be parsed as a version.**
-
-## Arguments
-
-- `$ARGUMENTS` - Required: the target version string (e.g., `17.3.4`, `18.0.0-rc`)
-
-## Files to Update
-
-The following 5 files must be updated with the new version:
-
-| # | File | Field |
-|---|------|-------|
-| 1 | `version.json` | `"version"` |
-| 2 | `src/Umbraco.Web.UI.Client/package.json` | `"version"` |
-| 3 | `src/Umbraco.Web.UI.Client/package-lock.json` | top-level `"version"` AND `packages[""].version` |
-| 4 | `tests/Umbraco.Tests.AcceptanceTest/package.json` | `"version"` |
-| 5 | `tests/Umbraco.Tests.AcceptanceTest/package-lock.json` | top-level `"version"` AND `packages[""].version` |
-
-**Note**: For major version bumps (e.g., 17.x to 18.x), `src/Umbraco.Web.UI.Login/package.json` has a caret-ranged dependency on `@umbraco-cms/backoffice` (e.g., `^17.2.0`) that will need manual updating. This skill does not handle that — major bumps involve many other changes beyond version strings.
-
-## Instructions
-
-### 1. Parse and Validate the Version
-
-Extract the version from `$ARGUMENTS`. It must be a valid semver-like string (e.g., `17.3.4`, `18.0.0-rc`, `17.4.0-preview.1`). If no version is provided or it cannot be parsed, ask the user for the target version.
-
-### 2. Read the Current Version
-
-Read `version.json` and extract the current `"version"` value. If the current version already equals the target version, report that the version is already set and stop — do not edit, stage, or commit anything.
-
-Otherwise, display both versions:
-
-```
-Bumping version: {current} -> {target}
-```
-
-### 3. Update All Files
-
-Update each of the 5 files listed above, replacing the old version with the new version. For each file:
-
-- **`version.json`**: Replace the `"version"` value.
-- **`package.json` files**: Replace the `"version"` value (near the top of the file).
-- **`package-lock.json` files**: Replace BOTH the top-level `"version"` value AND the `"version"` inside the `"packages": { "": { ... } }` block. These are always in the first ~10 lines of the file.
-
-Use targeted edits — do NOT rewrite entire files. Be precise to avoid changing version strings in dependency entries.
-
-### 4. Verify
-
-After all edits, grep for the target version value across the 5 files to confirm all updates landed correctly:
-
-```bash
-grep -n "\"version\": \"{version}\"" version.json src/Umbraco.Web.UI.Client/package.json src/Umbraco.Web.UI.Client/package-lock.json tests/Umbraco.Tests.AcceptanceTest/package.json tests/Umbraco.Tests.AcceptanceTest/package-lock.json
-```
-
-Expect exactly 7 matches (one per `package.json` and `version.json`, two per `package-lock.json`).
-
-### 5. Stage and Commit
-
-Stage only the 5 changed files:
-
-```bash
-git add version.json src/Umbraco.Web.UI.Client/package.json src/Umbraco.Web.UI.Client/package-lock.json tests/Umbraco.Tests.AcceptanceTest/package.json tests/Umbraco.Tests.AcceptanceTest/package-lock.json
-```
-
-Then commit with the message `Bump version to {version}.` — replacing `{version}` with the target version:
-
-```bash
-git commit -m "Bump version to {version}."
-```
-
-### 6. Report
-
-Output a summary:
-
-```
-Version bumped to {version} in:
-- version.json
-- src/Umbraco.Web.UI.Client/package.json
-- src/Umbraco.Web.UI.Client/package-lock.json
-- tests/Umbraco.Tests.AcceptanceTest/package.json
-- tests/Umbraco.Tests.AcceptanceTest/package-lock.json
-
-Changes staged and committed.
-```

-# PR Review - Umbraco CMS
-
-Automated, non-interactive PR code review. Analyzes changed files for intent, impact on consumers, breaking changes, architecture compliance, and code quality.
-
-**Do NOT use AskUserQuestion at any point. This skill runs fully autonomously.**
-
-## Arguments
-
-- `$ARGUMENTS` - Optional: target branch to diff against (auto-detected from PR, falls back to `origin/main`)
-
-## Instructions
-
-### 0. Verify GH CLI is Available
-
-Run `gh auth status`. If it fails, read `references/gh-cli-setup.md` and present the setup instructions to the user. Do not proceed with the review.
-
-### 1. Resolve Target Branch
-
-Determine the target branch for comparison using this priority order:
-
-1. **Explicit argument**: If `$ARGUMENTS` is provided and non-empty, use it as the target branch
-2. **PR target branch**: If no argument, run `gh pr view --json baseRefName --jq '.baseRefName'` to detect the target branch of the current branch's open PR. If a PR exists, use `origin/{baseRefName}` as the target branch.
-3. **Fallback**: If no argument and no PR found (command fails or returns empty), default to `origin/main`
-
-Store the resolved target branch for use in subsequent steps. Log which resolution method was used (e.g., "Target branch: `origin/v18/dev` (from PR #1234)").
-
-### 2. Load Review Standards
-
-#### 2a. Load coding preferences
-
-Read the coding preferences and code review scoring criteria from:
-
-- `references/coding-preferences.md` (relative to this skill file)
-
-Parse and internalize all rules, conventions, scoring categories, and severity definitions. These are your review criteria.
-
-#### 2b. Load area-specific documentation
-
-Once the changed file list is known (after step 3a), determine which areas of the codebase are touched and load the relevant documentation. Execute this sub-step between 3a and 3b. This documentation takes precedence over sibling comparison for architectural and pattern validation.
-
-**Resolution order for each changed file:**
-
-1. **Find the nearest `CLAUDE.md`** — walk up from the changed file's directory toward the repository root. The first `CLAUDE.md` found is the area guide for that file. Read it.
-2. **Read referenced docs** — if the `CLAUDE.md` references documentation files (e.g., a `docs/` directory), use the descriptions in the `CLAUDE.md` to determine which docs are relevant to the type of code being changed, and read those. If unsure, read all referenced docs — the cost of reading is low, the cost of missing a convention is high.
-3. **Follow cross-references in loaded docs** — if a loaded doc references another doc as covering a complementary or related concern, and the changed files touch that concern, read the referenced doc too. Repeat until no new relevant cross-references remain.
-4. **Check for applicable skills** — review the available skills list. If a skill exists for the type of code being changed, read the skill file to understand the expected patterns, structure, and conventions it enforces. Do NOT invoke the skill — just use it as a reference for what the correct implementation should look like.
-
-**Store all loaded documentation** for use in step 4. These docs define the authoritative patterns and conventions that the review evaluates against.
-
-### 3. Gather Changed Files
-
-#### 3a. Collect file list, stats, and diff
-
-Run these git commands (where `{target}` is the resolved target branch):
-
-```bash
-git diff {target}...HEAD --name-only --diff-filter=d   # changed files (excluding deleted)
-git diff {target}...HEAD --stat                         # line counts per file
-git log {target}...HEAD --oneline                       # commit history
-git diff {target}...HEAD                                # full diff (primary review source)
-```
-
-**If no changes found**: Output "No changes found between current branch and `{target}`. Nothing to review." and stop.
-
-#### 3b. Filter out noise files
-
-From the changed file list, classify each file as **noise** or **reviewable**.
-
-**Noise files** (skip entirely — do not read, do not review):
-
-| Pattern                                              | Reason                          |
-| ---------------------------------------------------- | ------------------------------- |
-| `*.gen.ts`, `*.gen.cs`                               | Auto-generated API client code  |
-| `*.generated.cs`, `*.Designer.cs` (in `Migrations/`) | Auto-generated models/snapshots |
-| `*/assets/lang/*.ts` (except `en.ts`)                | Non-English translation files   |
-| `*/mocks/data/*.ts`                                  | Test fixture data               |
-| `*/dist-cms/*`, `*/storybook-static/*`               | Build output                    |
-| `*/TEMP/InMemoryAuto/*`                              | Runtime-generated models        |
-| `package-lock.json`                                  | Dependency lock file            |
-| `appsettings-schema.*.json`                          | Generated JSON schema           |
-
-Log the skip list: "Skipped {N} noise files: {comma-separated list of filenames}"
-
-#### 3c. Read reviewable changed files
-
-Read the full file for every reviewable changed file.
-
-#### 3d. Track file counts
-
-Keep track of these numbers for the review output in step 7: total changed files, noise files skipped, and reviewable files read. Also record: distinct production layers touched, distinct project directories, and total lines changed — these feed step 3e.
-
-#### 3e. Assess PR complexity
-
-Follow the procedure in `references/complexity-assessment.md`. Store the triggered dimensions and suggestions for step 7.
-
-#### 3f. Classify PR scope
-
-Classify the PR to determine which review steps are relevant:
-
-| Classification  | Condition                                                                       | Effect                                                                          |
-| --------------- | ------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- |
-| **Gen-only**    | All reviewable files are `gen.ts`                                               | Skip steps 5 and 6; step 4 reviews impact on other code only                    |
-| **Docs-only**   | All reviewable files are `.md`                                                  | Skip steps 5 and 6; step 4 reviews intent and readability only                  |
-| **Test-only**   | All reviewable files are in `tests/`                                            | Skip steps 5 and 6; step 4 reviews intent, code quality, and test coverage only |
-| **Config-only** | All reviewable files are `.csproj`, `.props`, `.json` config, or CI/build files | Skip step 5; step 6 checks dependency version changes only                      |
-| **Standard**    | Anything else                                                                   | No skips — run all steps                                                        |

-### 4. Raw Code Review
-
-Review each changed file holistically. Think like a senior developer reading a colleague's PR. Note all findings without worrying about format or severity yet.
-
-#### 4a. Read and reason about each file
-
-For each changed file, reason about: What does this code do? Is it correct? What's missing — validation, error handling, notifications, cleanup, edge cases? Could this break anything for consumers?
-
-#### 4b. Validate against documentation and patterns
-
-Use a **docs-first** approach: classify the code by what it does, check it against documented conventions, and only fall back to sibling comparison when docs don't cover the pattern.
-
-**Step 1 — Determine the correct approach from documentation, then check whether the PR matches**
-
-A PR is a proposed solution, not the source of truth. This step has two parts that must happen in order — do not start part B until part A is complete.
-
-**Part A — Before validating/judging the implementation**, determine what the correct approach is for each new class or file based on what it does. Use the documentation loaded in step 2b to identify the expected base classes, patterns, and conventions. Write down the expected approach. Classify based on what the code does, not based on what neighboring files look like.
-
-**Part B — Now compare the PR's implementation** against the expected approach from Part A. If it deviates from the documented approach, flag it. If the documentation specifies reference examples, read those examples to verify the implementation matches.
-
-**Pattern match is the leading finding.** If the documentation defines a pattern that fits what the code does, the first and most important finding is whether the code follows that pattern.
-
-**Step 2 — Fall back to sibling comparison**
-
-If the documentation does not cover the specific pattern, or for cross-cutting concerns not addressed in docs, fall back to sibling comparison:
-
-1. **New method on existing class/interface**: Grep for the most similar existing method on the same class using `-A 80` to capture the full method body (e.g., `UpdateCurrentUserAsync` → grep for `UpdateAsync` in the same file with `-A 80`). Compare line by line for missing cross-cutting concerns: notifications/events, validation, scoping, authorization, error handling, audit logging.
-2. **New TS class**: Grep for siblings by base class (`extends {BaseClass}`) or by interface (`implements {Interface}`) or by name suffix (e.g., `CurrentUserController` → grep for `UserController`). Compare for missing concerns.
-3. **New CS class**: Grep for siblings by base class (`class {ClassName} : {BaseClass}`) or by interface (`class {ClassName} : {Interface}`) or by name suffix (e.g., `ManagementApiComposer` → grep for `ApiComposer`). Compare for missing concerns.
-
-**Important:** Sibling comparison validates cross-cutting concerns, but it must not override documented conventions. If a sibling deviates from documented patterns, that sibling is wrong — do not copy its deviation.
-
-Store your raw findings — they feed into step 7.
-
-### 5. Impact Analysis
-
-**Skip this step if PR scope is docs-only, test-only, or config-only.**
-
-Follow the procedure in `references/impact-analysis.md`.
-
-### 6. Breaking Changes Check
-
-**Skip this step if PR scope is docs-only or test-only. If config-only, only check for dependency version changes that could break consumers.**
-
-Follow the procedure in `references/breaking-changes.md`.
-
-### 7. Consolidate and Output Review
-
-Merge findings from step 4 (raw review), step 5 (impact analysis), and step 6 (breaking changes). For each finding, assign severity (Critical/Important/Suggestion) and verify it relates to changed code — not pre-existing issues. Before outputting, drop any finding about whitespace, blank lines, formatting, or comment wording. Then present the review in this exact format:

-
-**Guidelines for the review output:**
-
-— When reporting information, be extremely concise and sacrifice grammar for sake of concision.
-
-- Only review code that was changed in the diff — pre-existing issues are out of scope. Focus on what compilers and linters cannot catch: behavioral side-effects (e.g., a changed default alters runtime behavior for consumers), architectural violations (e.g., a new dependency breaks layering), breaking changes for external consumers of the public API, and security implications. Leave type errors, missing imports, and broken references to CI.
-- Be specific — always reference file and line number
-- Explain WHY something is an issue, not just WHAT, but avoid stating the obvious.
-- For complex matters, provide concrete fix suggestions, including code snippets when helpful
-- Keep it constructive — the goal is to help, not gatekeep
-- Don't repeat the same finding for every occurrence — mention it once and note "same pattern in {other files}"
-- Focus on substantive issues only. Do NOT flag purely cosmetic or stylistic concerns. Specifically, never flag: code formatting or whitespace, comment grammar or wording, redundant-but-harmless syntax (e.g., optional chaining after a truthiness check), code duplication that doesn't cause bugs, or HTML template cosmetics. The only exception is when a stylistic issue has a concrete impact on performance or rendering. Note: missing JSDoc/documentation on public or exported APIs is a substantive finding (per coding preferences), not a cosmetic one — flag it as a Suggestion.
-- For breaking changes, reference the specific pattern from the CLAUDE.md that should be applied
-- Do not suggest changes that would themselves introduce breaking changes. If a suggestion would alter public API surface (e.g., changing return types, renaming public members), it is not appropriate for a PR targeting `main` within a major version. Only suggest non-breaking alternatives.

-# Breaking Changes Reference
-
-This document describes how to detect and validate breaking changes during PR review. It covers both backend (.NET) and frontend (TypeScript/Lit) patterns.
-
----
-
-## Version Detection
-
-**Always read `version.json`** at the repository root to determine the current major version. This drives the obsolete removal target calculation:
-
-- Current major version: read from `version.json` → `version` field (e.g., `"17.4.0-rc"` → major version `17`)
-- Obsolete removal target: `current + 2` (e.g., if current is 17, removal is scheduled for Umbraco 19)
-- Format: `[Obsolete("... Scheduled for removal in Umbraco {current+2}.")]`
-
----
-
-## Backend (.NET) Breaking Changes
-
-### What Constitutes a Breaking Change
-
-Any of these on a `public` or `protected` member:
-
-- Removing or renaming a class, interface, struct, record, or enum
-- Removing or renaming a method, property, or field
-- Changing a method signature (parameters, return type)
-- Adding required parameters to an existing method
-- Adding methods to a public interface (without default implementation)
-- Changing a constructor signature on a public class
-- Removing or changing enum values
-- Changing type hierarchy (base class, implemented interfaces)
-
-### Pattern 1: Obsolete Constructor + StaticServiceProvider
-
-When a public class needs new dependencies, the existing constructor must be preserved.
-
-**Correct pattern:**
-
-```csharp
-[Obsolete("Please use the constructor with all parameters. Scheduled for removal in Umbraco 19.")]
-public MyService(IDependencyA depA)
-    : this(
-        depA,
-        StaticServiceProvider.Instance.GetRequiredService<IDependencyB>())
-{
-}
-
-public MyService(IDependencyA depA, IDependencyB depB)
-{
-    _depA = depA;
-    _depB = depB;
-}
-```
-
-**Validation checklist:**
-
-- [ ] Old constructor has `[Obsolete]` attribute with correct removal version
-- [ ] Old constructor calls new constructor via `: this(...)`
-- [ ] `StaticServiceProvider.Instance.GetRequiredService<T>()` used for new params only
-- [ ] DI registration uses the NEW constructor (old is for external consumers only)
-- [ ] Removal version is `{current_major + 2}`
-
-**Common mistakes to flag:**
-
-- Removing the old constructor entirely (breaking change!)
-- Old constructor NOT calling new constructor (code duplication)
-- Wrong removal version in `[Obsolete]`
-- Missing `StaticServiceProvider` resolution for new dependencies
-- DI registration still using the old constructor
-
-### Pattern 2: Obsolete Method + New Overload
-
-When a method signature needs to change, add the new overload and obsolete the old.
-
-**Correct pattern:**
-
-```csharp
-[Obsolete("Use the overload taking all parameters. Scheduled for removal in Umbraco 19.")]
-public void DoThing(string name)
-    => DoThing(name, extraParam: null);
-
-public void DoThing(string name, string? extraParam)
-{
-    // Real implementation here
-}
-```
-
-**Validation checklist:**
-
-- [ ] Old method has `[Obsolete]` attribute with correct removal version
-- [ ] Old method calls new method, providing defaults for new parameters
-- [ ] All internal callers updated to use the new method
-- [ ] No internal code references the obsolete method (except the delegation)
-
-### Pattern 3: Default Interface Implementation
-
-When adding methods to a public interface, provide a default implementation.
-
-**Correct pattern:**
-
-```csharp
-public interface IMyService
-{
-    void ExistingMethod();
-
-    // New method with default implementation
-    void NewMethod(string param)
-        => ExistingMethod(); // delegate to existing if possible
-}
-```
-
-**Strategies for defaults (in order of preference):**
-
-1. Use existing interface methods to satisfy the contract
-2. Return a sensible default (empty collection, null, etc.)
-3. Throw `NotImplementedException` if no reasonable default exists
-
-**Validation checklist:**
-
-- [ ] New interface method has a default implementation
-- [ ] TODO comment present: `// TODO (V{next-major}): Remove the default implementation when {obsolete method} is removed.`
-- [ ] Default implementation is functionally correct (even if not optimal)
-- [ ] If `StaticServiceProvider` is used in default impl, noted as temporary
-
-### Obsolete Attribute Validation
-
-For any `[Obsolete]` attribute found in changed code:
-
-1. **Format**: Must contain `"Scheduled for removal in Umbraco {version}."`
-2. **Version**: Must be `current_major + 2` (read from `version.json`)
-3. **Pragma**: Where obsolete members must call each other, `#pragma warning disable CS0618` / `#pragma warning restore CS0618` must be present
-
-### Internal Caller Check
-
-After finding obsolete patterns, verify:
-
-- Search the codebase for usages of the obsolete member
-- **No internal code** (inside `src/`) should reference obsolete members
-- Only the obsolete member's own delegation (calling the new version) is acceptable
-- External consumers (outside the repo) get the deprecation period to migrate
-
----
-
-## Frontend (TypeScript/Lit) Breaking Changes
-
-The backoffice is published as `@umbraco-cms/backoffice` with 140+ named exports. Plugin developers depend on this public API surface.
-
-**Critical frontend rule (does not apply to backend .NET where `public`/`protected` visibility determines the API surface): only symbols reachable through the `package.json` `exports` field are public API.** Anything not exported — whether classes, functions, constants, types, or entire files — is an internal implementation detail, even if other internal code imports it. Removing or changing unexported frontend symbols is not a breaking change. Before flagging a frontend deletion or rename as breaking, verify the symbol is reachable via `package.json` exports. If it is not, do not flag it.
-
-### Custom Elements (Web Components)
-
-**Breaking changes:**
-
-- Renaming or removing a registered custom element tag (`umb-*`)
-- Removing elements from `HTMLElementTagNameMap`
-- Removing or changing `@property()` decorated fields on exported components
-- Removing event emissions (checked via `this.dispatchEvent`)
-- Removing CSS custom properties (`@cssprop` in JSDoc)
-- Removing CSS parts (`@csspart` in JSDoc)
-
-**How to detect:**
-
-- Check diff for removed `@customElement('umb-...')` decorators
-- Check diff for removed `@property()` fields on exported components
-- Check diff for removed entries in `HTMLElementTagNameMap` declarations
-
-### Exported Types/Interfaces
-
-**Breaking changes:**
-
-- Removing exports from `package.json` `exports` field
-- Changing the shape of exported interfaces (removing properties, changing types)
-- Renaming exported types (consumers import by name)
-- Removing union type members
-- Changing generic type parameter constraints
-
-**How to detect:**
-
-- Check if `package.json` `exports` field is modified
-- Check diff for removed `export` statements
-- Check diff for changed interface/type shapes
-
-### Manifest/Extension System
-
-**Breaking changes:**
-
-- Renaming a manifest `alias` value — plugin developers reference aliases by string in conditions, overwrites, and extension registry lookups. Alias renames are not caught by the compiler since they are string-based. A renamed alias silently breaks any plugin that references the old string.
-- Removing support for a manifest `type` that plugins use
-- Changing manifest `alias` resolution or validation
-- Removing or renaming manifest `kind` types
-- Changing extension bundle structure
-
-**How to detect:**
-
-- **Alias renames**: Compare `alias:` values in manifest files before and after. Changed alias strings are Critical — the old alias should be preserved as a deprecated entry.
-- Search for changes to manifest type definitions
-- Check for removed or renamed manifest kinds
-
-### Context API
-
-**Breaking changes:**
-
-- Removing context tokens from exports
-- Changing the shape of data provided by a context
-- Removing context provider/consumer mechanisms
-
-**How to detect:**
-
-- Check for removed context token exports
-- Check for changes to context provider classes
-
-### Controllers/Lifecycle
-
-**Breaking changes:**
-
-- Changing controller base class inheritance requirements
-- Removing controller lifecycle hooks
-- Breaking cleanup mechanisms in `disconnectedCallback()`
-
-### Observable/State
-
-**Breaking changes:**
-
-- Removing observable properties from the public API
-- Changing observable emission patterns
-
-### npm Publishing
-
-**Breaking changes:**
-
-- Changing version constraints that exclude previously-supported versions
-- Adding incompatible peer dependency constraints
-
-**How to detect:**
-
-- Check if `package.json` `peerDependencies` or `dependencies` changed
-- Verify version ranges are not narrowed
-
----
-
-## Reporting Breaking Changes
-
-When a breaking change is detected, report:
-
-1. **What**: The specific change and which public symbol is affected
-2. **Pattern**: Which mitigation pattern should be applied (Pattern 1, 2, or 3 for backend)
-3. **Severity**: Critical (no mitigation present) or Important (mitigation present but incorrect)
-4. **Fix**: Concrete code suggestion showing the correct pattern
-
-If no breaking changes are detected, state: "No breaking changes detected."

-# Coding Preferences & Review Criteria
-
-These are the coding preferences and code review standards used by the review skill. They define what the review evaluates against.
-
----
-
-## Testing
-
-- **Always create blackbox tests** for new/changed code
-- Choose the appropriate test level:
-  - **Unit tests** for isolated logic
-  - **Integration tests** for application services/use cases
-  - **E2E tests** for API endpoints
-
-### Test Class Naming
-
-- Test classes must be postfixed with `Tests` (e.g., `OrderServiceTests`)
-- One test class per class under test
-
-### Test Method Naming
-
-**C# tests**: Use the `Can_`/`Cannot_` pattern with PascalCase underscore-separated words:
-
-- `Can_Schedule_Publish_Invariant`
-- `Cannot_Delete_Non_Existing`
-- `Can_Schedule_Publish_Single_Culture`
-
-Large test classes are split into partial files by method: `ContentServiceTests.Delete.cs`, `ContentServiceTests.Publish.cs`.
-
-**TypeScript tests**: Use BDD-style `it()` with natural language descriptions:
-
-- `it('should not allow the returned value to be lower than min')`
-- `it('converts string to camelCase')`
-
-### Unit Tests
-
-- Optional, but must be blackbox tests so refactoring does not break tests
-
-### Integration Tests
-
-- Every use case / application service must have integration tests
-- Tests run against real database (containerized or similar)
-- Test the full flow from application layer through infrastructure
-
-### E2E Tests
-
-- Every API endpoint must have E2E tests
-- Test realistic scenarios including error cases
-
----
-
-## Trade-offs
-
-When making decisions, prioritize:
-
-- **Readability** over cleverness
-- **Flexibility** over rigidity
-- Explain trade-offs when deviating from these defaults
-
----
-
-## Breaking Changes
-
-- Communicate breaking changes at the **OpenAPI/openapi.json level**
-- Clearly document what changed and the migration path
-
----
-
-## Documentation
-
-- **Document all public or exported types** (classes, interfaces, types, methods, properties)
-- Keep documentation in sync with code changes
-- Add **JS Docs** on all public frontend APIs (classes, methods, properties)
-- Focus on "why" and usage, not restating the obvious
-
----
-
-## Dependencies
-
-- Use what's available in the codebase, unless there is no good choice
-- **Flag new dependencies** for review — new packages should be justified
-- Prefer well-maintained, widely-used packages
-
----
-
-## Error Messages & Logging
-
-- **User-facing errors**: Clear, friendly, actionable
-- **Log messages**: Technical, detailed, with context
-- Include correlation IDs and relevant data in logs
-
----
-
-## Security
-
-- **Always check for security issues** using OWASP Top 10 as baseline
-- Flag potential vulnerabilities immediately
-- Suggest secure alternatives when spotting risky patterns
-- Apply principle of least privilege
-
----
-
-## Immutability
-
-- Prefer **immutability** by default
-- Allow internal properties to be mutated, as long as they are not direct references coming from the outside
-
----
-
-## Nullability
-
-- **TypeScript / JavaScript**
-  - Prefer `undefined` for optional/omitted values (e.g., optional parameters, props, and fields)
-  - Use `null` only when the domain model explicitly encodes "no value" or "not set" (e.g., `string | null` from APIs/DB), and be consistent with existing types
-  - Avoid mixing `null` and `undefined` for the same concept within the same model or API surface
-  
-- **C#**  
-  - use nullable types (e.g., `string?`, `int?`) where absence is valid
-  - Prefer domain modeling (value objects, options/results, empty collections) over `null` where appropriate, but respect existing conventions in the codebase
-
----
-
-## C# Specific
-
-- use Notification pattern (not C# events), Composer pattern (DI registration), Scoping with `Complete()`, Attempt pattern for operation results.
-
----
-
-## Architecture
-
-- Follow **Clean Architecture** principles
-- **Fail-fast** principle: detect and report errors as early as possible
-- Within the established layered architecture (Core/Infrastructure/Web/API), organize code by feature inside each layer where practical, while preserving dependency direction
-- One class per file
-- Avoid N+1 queries
-- Profile before optimizing non-critical paths
-
-### Type Hierarchy Consistency
-
-When parallel model types have inconsistent relationships to a shared base type:
-
-**TypeScript**: manipulations via `Omit`, `Pick`, intersection overrides, or workarounds like `as unknown as` / double-casts to bridge type mismatches.
-
-**C#**: hiding base members with `new` to change types, explicit interface implementations to mask mismatches, or downcasting base return types in derived classes.
-
-- **Do NOT suggest** the PR code should deviate from its base type to match a sibling that already deviates. Copying the deviation spreads the problem.
-- **Do flag** the architectural inconsistency: parallel models should share a compatible base contract. The model that manipulates or deviates from the base type is the one that needs attention — not the one that extends it correctly.
-- **Frame the suggestion** as: "These related models have inconsistent type hierarchies. `{deviating type}` manipulates the base contract of `{base type}`, which forces shared consumers like `{shared utility}` to require a shape that conforming subtypes can't satisfy."
-
----
-
-## Code Style
-
-- Follow standard naming conventions for the language (C# or JS/TS)
-- Keep components small and focused on a single responsibility
-- Prefer early returns
-- Small functions
-- No nested ternaries
-
----
-
-## Severity Levels
-
-| Severity | Meaning |
-|----------|---------|
-| **Critical** | Must fix before merge — security vulnerabilities, data loss risks, broken functionality |
-| **Important** | Should fix — performance issues, missing tests, architectural violations |
-| **Suggestion** | Nice to have — readability, minor refactoring, alternative approaches |

-# PR Complexity Assessment
-
-Evaluate whether the PR's scope suggests it should be split. This assessment is **informational only** — it never blocks or shortens the review.
-
-## Always check: Formatting mixed with logic
-
-This check applies to every PR regardless of size or scope.
-
-Run both commands and compare per-file line counts:
-```bash
-git diff {target}...HEAD --stat
-git diff {target}...HEAD --stat --ignore-all-space
-```
-
-For any file where the whitespace-ignored diff is less than **half** the full diff size (and the full diff is over 50 lines), that file has significant formatting changes mixed with logic. Flag it with a split suggestion: "File(s) {list} contain significant formatting changes mixed with logic. Consider a separate formatting-only commit or PR to keep the functional diff reviewable."
-
-## Multi-project scope check
-
-Skip this section entirely if ALL production files reside in a single project directory or if the PR is docs-only, test-only, dependency-bump-only, or rename-only.
-
-Otherwise, flag any dimension that applies:
-
-| Dimension | Condition | Suggestion |
-|---|---|---|
-| **Size** | 30+ files OR 1500+ lines, spanning 2+ projects | "If changes in {projectA} and {projectB} are independently functional, they could be separate PRs." |
-| **Layer spread** | 3+ layers touched (Core/Infrastructure/Web/API/Frontend), 10+ files | "Consider splitting by layer — e.g., Core+Infrastructure first, then API/Frontend consumers." |
-| **Mixed intent** | 2+ intent categories (new feature, bugfix, refactor, dependency update) with 15+ files or 3+ projects | "Consider extracting the {secondary intent} into a separate PR." |
-
-Intent categories — detect from diff characteristics, not commit messages:
-- **New feature**: new files or new `public`/`export` declarations
-- **Bug fix**: small targeted edits, no new files (don't co-flag with new feature)
-- **Refactor**: file renames, symbols moved but logic unchanged
-- **Dependency update**: changes to `.csproj`, `Directory.Packages.props`, `package.json`

-# Impact Analysis Reference
-
-This document describes how to perform impact analysis during PR review. The goal is to look beyond the diff to understand how changes affect consumers in other parts of the codebase.
-
----
-
-## 1. Extract Changed Public Symbols
-
-Scan the diff output for changes to public API surface:
-
-### Backend (.NET)
-
-Look for added, modified, or removed lines containing:
-
-- `public class`, `public abstract class`, `public sealed class`
-- `public interface`
-- `public record`, `public struct`, `public enum`
-- `public` or `protected` methods, properties, fields
-- `public static` members
-- Constructor signatures on public types
-
-### Frontend (TypeScript/Lit)
-
-Look for changes to:
-
-- `export class`, `export interface`, `export type`, `export enum`
-- `export function`, `export const`
-- `@property()` decorated fields on exported components
-- `@customElement()` registrations
-- Entries in `package.json` `exports` field
-
-Collect a list of all changed public symbol names (type names, method names, property names).
-
----
-
-## 2. Search for Consumers
-
-For each changed public symbol, search the `src/` directory for usages **outside the changed file itself**.
-
-### Grep Strategy
-
-Use the Grep tool with these settings:
-
-```
-pattern: {symbol name}
-path: src/
-output_mode: files_with_matches
-head_limit: 20
-```
-
-Use `head_limit: 20` to avoid overwhelming results — if there are more than 20 consumers, note "20+ consumers found" and list the first 20.
-
-### What to Search For
-
-For each changed type/method, search for:
-
-- **Type references**: class name, interface name (e.g., `IContentService`)
-- **Method calls**: method name in context (e.g., `\.GetById\(` for a method rename)
-- **Constructor usage**: `new TypeName(`
-- **DI registrations**: `.AddSingleton<IType, Type>`, `.AddScoped<`, `.AddTransient<`
-- **Notification handlers**: if a notification type changed, search for `INotificationHandler<NotificationTypeName>` and `INotificationAsyncHandler<NotificationTypeName>`
-- **Interface implementations**: if an interface changed, search for `: IInterfaceName` or `IInterfaceName,`
-
-### Excluding the Changed File
-
-When reporting consumers, exclude files that are part of the PR's changes (they're already being reviewed). The interesting consumers are those **outside** the PR that may be affected.
-
----
-
-## 3. Check Dependency Flow Direction
-
-The Umbraco architecture enforces strict unidirectional dependencies:
-
-```
-Api.Management / Api.Delivery (depend on Api.Common)
-  ↓
-Api.Common (depends on Web.Common)
-  ↓
-Web.Common (depends on Infrastructure)
-  ↓
-Infrastructure (depends on Core)
-  ↓
-Core (no dependencies)
-```
-
-### Layer Mapping
-
-Map each changed file to its architectural layer:
-
-| Path prefix | Layer |
-|---|---|
-| `src/Umbraco.Core/` | Core |
-| `src/Umbraco.Infrastructure/` | Infrastructure |
-| `src/Umbraco.PublishedCache.*` | Infrastructure |
-| `src/Umbraco.Examine.Lucene/` | Infrastructure |
-| `src/Umbraco.Cms.Persistence.*` | Infrastructure |
-| `src/Umbraco.Web.Common/` | Web |
-| `src/Umbraco.Web.UI/` | Web (Application) |
-| `src/Umbraco.Web.Website/` | Web |
-| `src/Umbraco.Cms.Api.Common/` | API |
-| `src/Umbraco.Cms.Api.Management/` | API |
-| `src/Umbraco.Cms.Api.Delivery/` | API |
-| `src/Umbraco.Web.UI.Client/` | Frontend |
-| `tests/` | Test |
-
-### Violation Detection
-
-Flag if a change introduces:
-
-- **Core depending on Infrastructure**: Core file importing/referencing Infrastructure types
-- **Core depending on Web/API**: Core file importing/referencing Web or API types
-- **Infrastructure depending on Web/API**: Infrastructure file importing Web or API types
-- **Cross-API dependencies**: Management API depending on Delivery API or vice versa
-
-### How to Check
-
-1. For each changed file, identify its layer
-2. Read the file's `using` statements (C#) or `import` statements (TS)
-3. Check if any imports reference a higher layer
-4. Also check if new parameters or return types come from higher layers
-
----
-
-## 4. Flag Cross-Project Risks
-
-### High-Risk Patterns
-
-These changes have high ripple potential:
-
-- **Interface changes in Core** — all implementations in Infrastructure must be updated
-- **Notification type changes** — all handlers across the codebase are affected
-- **Base class changes** — all derived classes are affected
-- **Composer changes** — can affect DI container and runtime behavior globally
-- **Shared model/DTO changes** — can affect serialization, API contracts, and consumers
-
-### What to Report
-
-For each cross-project risk found, report:
-
-1. **What changed**: The specific symbol and how it changed
-2. **Who is affected**: List of consuming files/projects found via Grep
-3. **Risk level**: Whether the consumers will break (compile error), behave differently (runtime), or are unaffected
-4. **Recommendation**: Whether the PR should include updates to affected consumers
-
----
-
-## 5. Performance Notes
-
-- Use `head_limit: 20` on all Grep searches to cap results
-- Only search for symbols that actually changed (not every symbol in the file)
-- For very common type names (e.g., `IScope`, `ILogger`), consider adding more context to the search pattern to reduce false positives
-- Skip impact analysis for test files — they don't have external consumers
-- Skip impact analysis for private/internal members — they can't have external consumers

-# **Contributing to Localization in the Backoffice**
-
-Do you want to help keep our translations accurate and up to standard? 🌍✨
-
-Your input makes a real difference! By reviewing, refining, or suggesting improvements, you ensure that our translations remain clear, consistent, and user-friendly for everyone.
-
-
-## **How Can I Contribute?**
-
-To contribute to localization in the Backoffice, follow this step-by-step guide:
-
-
-### **1. Change the Language in Backoffice**
-
-
-
-1. Open the Backoffice, click on your profile icon in the top-right corner, and select "Edit." 
-
-
-
-![Menubar profile image](/.github/img/contributing/ProfileImage.png "Menubar profile image")
-
-
-
-![Edit button inside profile](/.github/img/contributing/editBtn.png "Edit button inside profile")
-
-
-2. Under "UI Culture," select the language you want to review from the dropdown menu. 
-
-
-
-![Dropdown of languages in Umbraco](/.github/img/contributing/uiCulture.png "Dropdown of languages in Umbraco")
-
-
-
-### **2. Find a Translation Error**
-
-
-
-1. Navigate through the Backoffice and check if everything is translated correctly. 
-
-2. When you find a translation error, right-click on it and select "Inspect." 
-
-3. Look for the nearest element that starts with `umb-` and has a name indicating something specific to the given location. 
- 
-    **Example:**  
-
-    * The closest parent element should be specific, such as `umb-document-type-workspace-view-settings` instead of a generic element like `umb-property-layout.`
-
-
-### **3. Find the Code in VS Code**
-
-
-
-1. Open VS Code and search for the nearest `umb-` element you identified. 
-
-
-
-![Search for nearest umb element in code](/.github/img/contributing/searchInVsCode.png "Search for nearest umb element in code")
-
-2. Scroll down to find `render() {` and look for the element label that needs updating. 
-
-
-![Find render and label in code](/.github/img/contributing/renderCode.png "Find render and label in code")
-
-3. If the label is hardcoded, it must be updated. 
- 
-    **Example:**  
-    `label="Vary by culture"`
-
-
-### **4. Find the Correct Translation**
-
-
-
-1. Open the `en.ts` or `en-us.ts` file and search for relevant keywords. \
- \
-    **Example:** 
-
-    * If the text is "Vary by culture," search for `vary`, `culture`, or `Vary by culture`. 
-
-
-2. Once you find the translation, take the element name and search for it in the target language file (e.g., `da-dk.ts` for Danish). 
-
-
-![Search for translation in language files](/.github/img/contributing/searchingThroughLanguageFiles.png "Search for translation in language files")
-
-3. If a translation exists, insert it into the label element found earlier. 
-
-
-
-### **5. Insert the Translation**
-
-To display the new translation correctly, insert the following code inside the label element:
-
-`${this.localize.term('action_key')}`
-
-Replace `action_key` with the correct translation key.
-
-**Example:**
-
-`${this.localize.term('contentTypeEditor_allowVaryByCulture')}`
-
-![Localization code snippet](/.github/img/contributing/localizationCodeSnippetInCode.png "Localization code snippet")
-
-
-Save the changes and return to the Backoffice to see the update.
-
-
-![Changes in backoffice after changes in code](/.github/img/contributing/changedBackofficeAfterLocalization.png "Changes in backoffice after changes in code")
-
-
-
-### **6. Commit and Push**
-
-
-
-1. Commit your changes to a new temporary branch (avoid committing directly to `main`). 
-
-2. Push the changes to your fork on GitHub.
-
-
-### **7. Create a Pull Request**
-
-
-
-1. In your forked repository on GitHub (`https://github.com/[YourUsername]/Umbraco-CMS`), a banner will appear stating that you pushed a new branch. 
-
-2. Click the button to create a pull request and follow the instructions.
-
-
-## **I Can’t Find the Correct Translation**
-
-If you can’t find the translation you need, it may not exist yet. In this case, you can create a new action with related keys.
-
-
-### **1. Ensure It Doesn’t Already Exist**
-
-Search thoroughly in `en.ts` or `en-us.ts` for all relevant keywords.
-
-
-### **2. Create an Action**
-
-
-
-1. Choose a meaningful name for the action to avoid confusion. \
- \
- **Example:** Translation for the Data Type "Color Picker." 
-
-    * **Good name:** `colorPickerConfigurations`
-    * **Bad name:** `colorpicker`
-2. A specific action name prevents unnecessarily long key names. 
-
-3. Define the action: 
-
-
-
-### **3. Create Keys**
-
-
-
-1. Use clear and descriptive key names. \
- \
- **Example:**
-    * **Good name:** `colorsTitle`
-    * **Bad name:** `colors`
-2. Add the necessary keys inside the action with proper translations. 
-
-
-
-![Action and related Keys in language files](/.github/img/contributing/actionAndKeys.png "Action and related Keys in language files")
-
-
-
-## **I Can’t Find a <code>render()</code> Code in VS Code**
-
-In some cases, such as Data Types, the label might not be inside `render()`. Instead, it may be in a manifest file.
-
-
-### 1. Search for the Text
-
-Copy the text from the Backoffice and search for it in the code.
-
-
-### 2. Open the Manifest File
-
-Once you find the relevant manifest file, open it to confirm you’re in the right place.
-
-
-### 3. Change the Label
-
-In Markdown files, localization is slightly different. Instead of:
-`${this.localize.term('action_key')}`
-
-Use: `#action_key`
-
-**Example:**
-`#colorPickerConfigurations_showLabelTitle`
-
-### 4. Change the Description
-
-For descriptions in Markdown files, use:
-`{umbLocalize: action_key}`
-
-**Example:**
-`{umbLocalize: colorPickerConfigurations_showLabelDescription}`
-
-
-### 5. Save and Verify
-
-Once all changes are made, your manifest should look something like this:
-
-
-![Localization changes to manifest files](/.github/img/contributing/finishedManifestAfterLocalizatonChanges.png "Localization changes to manifest files")
-

-

-
-            Do NOT use sticky/updating comments — post new individual comments.
-
-            After reviewing, apply labels to the PR based on changed files:
-            - `area/frontend` — if files under `src/Umbraco.Web.UI.Client/` are changed
-            - `area/backend` — if .cs files outside the frontend client are changed

-            - `category/localization` — if localization/language files are changed
-            - `category/test-automation` — if only test files are changed
-            - `category/refactor` — if the PR is pure refactoring with no new features
-            - `category/performance` — if performance-related changes are detected

-
-            You were triggered on issue/PR #${{ github.event.issue.number || github.event.pull_request.number }}.
-
-            Read the user's message and do what they ask. The trigger phrase
-            `@claude` is stripped before you see the message, so common requests
-            will look like:
-
-            - `review` — Review PR #${{ github.event.issue.number || github.event.pull_request.number }}.
-              Use `gh pr diff ${{ github.event.issue.number || github.event.pull_request.number }}`

-              to read the changes. Do NOT use git diff or the umb-review skill.
-              Focus on bugs, breaking changes, and architectural concerns.
-              Post inline comments for specific issues and a brief summary.
-            - `help` or a general question — Answer based on the codebase.
-              Read CLAUDE.md files for project structure and conventions.
-            - `fix ...` — Implement the requested fix on a new branch.
-            - `label` — Apply appropriate labels to the PR or issue.
-
-            If the message is empty or just whitespace, treat it as `review`
-            when on a PR, or `help` when on an issue.
-
-            If none of these match, read the user's message carefully and respond
-            to what they actually asked for.
-
-            ## Labeling
-
-            When labeling PRs (based on changed files):

-            - `category/test-automation`
-
-            When labeling issues (based on content):
-            - `area/frontend`, `area/backend`, `area/test`
-            - `affected/v14` through `affected/v17`, `affected/backoffice`
-            - `category/api`, `category/localization`, `category/performance`
-            - `category/ux`, `category/ui`
-
-            Only apply labels you are confident about. Never remove existing labels.

-            ## Tone
-
-            Be friendly and constructive. Frame feedback as suggestions.
-            Reserve firm language for genuine critical issues only.
-
-            ## Constraints
-
-            - Run fully autonomously. Do NOT ask questions.
-            - Do not suggest changes that would introduce breaking changes.

-
-            Your task:
-            1. Use mcp__github__get_issue to get details of the current issue (#${{ github.event.issue.number || inputs.issue_number }})
-            2. Search for similar existing issues using mcp__github__search_issues with relevant keywords from the issue title and body
-            3. Compare the new issue with existing ones to identify potential duplicates
-
-            Criteria for duplicates:
-            - Same bug or error being reported
-            - Same feature request (even if worded differently)
-            - Same question being asked
-            - Issues describing the same root problem
-
-            If you find duplicates:
-            - Add a comment on the new issue linking to the original issue(s)
-            - Apply the "duplicate" and "state/needs-investigation" labels to the new issue
-            - Be polite and explain why it's a duplicate
-            - Suggest the user follow the original issue for updates
-
-            If it's NOT a duplicate:
-            - Don't add any comments
-            - You may apply appropriate topic labels based on the issue content
-
-            Use these tools:

-            - mcp__github__search_issues: Search for similar issues
-            - mcp__github__list_issues: List recent issues if needed
-            - mcp__github__add_issue_comment: Add a comment if duplicate found
-            - mcp__github__update_issue: Add labels
-

-### Architecture Layers
-
-**Dependency Flow** (unidirectional, always flows inward):
-
-```
-Web.UI → Web.Common → Infrastructure → Core
-                ↓
-          Api.Management → Api.Common → Infrastructure → Core
-                ↓
-          Api.Delivery → Api.Common → Infrastructure → Core
-```
-
-**Key Principle**: Core has NO dependencies (pure contracts). Infrastructure implements Core. Web/APIs depend on Infrastructure.
-
-### Project Dependencies
-
-**Core Layer**:
-- `Umbraco.Core` → No dependencies (only Microsoft.Extensions.*)
-
-**Infrastructure Layer**:
-- `Umbraco.Infrastructure` → `Umbraco.Core`
-- `Umbraco.PublishedCache.*` → `Umbraco.Infrastructure`
-- `Umbraco.Examine.Lucene` → `Umbraco.Infrastructure`
-- `Umbraco.Cms.Persistence.*` → `Umbraco.Infrastructure`
-
-**Web Layer**:
-- `Umbraco.Web.Common` → `Umbraco.Infrastructure` + caching + search
-- `Umbraco.Web.UI` → `Umbraco.Web.Common` + all features
-
-**API Layer**:
-- `Umbraco.Cms.Api.Common` → `Umbraco.Web.Common`
-- `Umbraco.Cms.Api.Management` → `Umbraco.Cms.Api.Common`
-- `Umbraco.Cms.Api.Delivery` → `Umbraco.Cms.Api.Common`

-## 3. Teamwork & Collaboration
-
-### Branching Strategy
-
-- **Main branch**: `main` (protected)
-- **Branch naming convention**: `v<version>/<type>/<description>`
-
-**Format**: `v{major-version}/{type}/{kebab-case-description}`
-
-**Version**: Read from `version.json` in the repository root. Use the major version number (e.g., `v17` for version 17.x.x).
-
-**Types**:
-| Type | Use Case |
-|------|----------|
-| `feature` | New feature being introduced to the product |
-| `bugfix` | Fix to an existing issue with the product |
-| `qa` | Adding or updating unit, integration, or end-to-end tests |
-| `improvement` | Update to something that already exists but isn't broken (UI finessing, refactoring) |
-| `task` | Update that doesn't directly impact product behavior (dependency updates, build pipeline) |
-
-**Description**: A short, kebab-case description (a few words). This should be prefixed with the GitHub issue number if the update is related to resolving a tracked issue.
-
-**Examples**:
-```
-v17/bugfix/12345-correct-display-of-pending-migrations
-v17/feature/add-webhook-support
-v17/improvement/optimize-content-cache
-v17/qa/add-media-service-tests
-v17/task/update-ef-core-dependency
-```
-
-See `.github/CONTRIBUTING.md` for full guidelines.
-
-### Pull Request Process
-
-- **PR Template**: `.github/pull_request_template.md`
-- **Required CI Checks**:
-  - All tests pass
-  - Code formatting (dotnet format)
-  - No build warnings
-- **Merge Strategy**: Squash and merge (via GitHub UI)
-- **Reviews**: Required from code owners
-
-#### PR Naming Convention
-
-Use the format: `Area: Description (closes #IssueID)`
-
-**Examples**:
-| Area | Description | Issue |
-|------|-------------|-------|
-| Relations: | Move persistence of relations from repository into notification handlers | (closes #00000) |
-| Management API: | Correct the population of the parent for sibling items when retrieved under a folder | |
-| Docs: | Updated contributing guidelines to welcome contributions on bugfixes | |
-
-**Area**: The feature or aspect affected (e.g., UFM, TipTap, Docs, Segmentation, Migrations). Helps readers quickly understand what is being changed.
-
-**Description Best Practices**:
-- Include the area of change (Relations, Management API, etc.)
-- Describe the change and its impact
-- Be specific, not vague (describe "a golden retriever" not just "a dog")
-
-**Issue Linking**: Add `(closes #IssueID)` to the title for readability, AND include a closing keyword on its own line in the PR body (e.g., `Fixes #IssueID`) so GitHub actually auto-links and auto-closes the issue on merge. GitHub only parses closing keywords (`closes`, `fixes`, `resolves`) from the PR body or commit messages — the title suffix is cosmetic and does **not** trigger auto-close on its own.
-
-### Commit Messages
-
-Follow Conventional Commits format:
-```
-<type>(<scope>): <description>
-
-Types: feat, fix, docs, style, refactor, test, chore
-Scope: project name (core, web, api, etc.)
-
-Examples:
-feat(core): add IContentService.GetByIds method
-fix(api): resolve null reference in schema handler
-docs(web): update routing documentation
-```
-
-### Code Owners
-
-Project ownership is distributed across teams. Check individual project directories for ownership.
-

-
-## 4. Architecture Patterns
-
-### Core Architectural Decisions
-
-1. **Layered Architecture with Dependency Inversion**
-   - Core defines contracts (interfaces)
-   - Infrastructure implements contracts that need Infrastructure-owned machinery
-   - Web/APIs consume implementations via DI
-
-   **Where service implementations live**: Services whose dependencies are satisfiable from Core interfaces alone (repositories, scope, config, other Core services) live in `Umbraco.Core/Services/` — this covers the majority of domain services (`MemberService`, `ContentService`, `MediaService`, `ContentTypeService`, `EntityService`, `AuditService`, `ExternalMemberService`, etc.). Service implementations only live in `Umbraco.Infrastructure/Services/Implement/` when they genuinely need Infrastructure concerns — Examine indexes (`ContentSearchService`, `MediaSearchService`, `IndexedEntitySearchService`), log files (`LogViewerRepository`), packaging internals (`PackagingService`), webhook firing (`WebhookFiringService`), distributed-job coordination (`DistributedJobService`). When adding a new service, default to Core and only move to Infrastructure if a concrete dependency forces it.
-
-2. **Interface-First Design**
-   - All services defined as interfaces in Core
-   - Enables testing, polymorphism, extensibility
-
-3. **Notification Pattern** (not C# events)
-   - See `/src/Umbraco.Core/CLAUDE.md` → "2. Notification System (Event Handling)"
-
-4. **Composer Pattern** (DI registration)
-   - See `/src/Umbraco.Core/CLAUDE.md` → "3. Composer Pattern (DI Registration)"
-
-5. **Scoping Pattern** (Unit of Work)
-   - See `/src/Umbraco.Core/CLAUDE.md` → "5. Scoping Pattern (Unit of Work)"
-
-6. **Attempt Pattern** (operation results)
-   - `Attempt<TResult, TStatus>` instead of exceptions
-   - Strongly-typed operation status enums
-
-### Key Design Patterns Used
-
-- **Repository Pattern** - Data access abstraction
-- **Unit of Work** - Scoping for transactions
-- **Builder Pattern** - `ProblemDetailsBuilder` for API errors
-- **Strategy Pattern** - OpenAPI handlers (schema ID, operation ID)
-- **Options Pattern** - All configuration via `IOptions<T>`
-- **Factory Pattern** - Content type factories
-- **Mediator Pattern** - Notification aggregator
-

-
-## 5. Avoiding Breaking Changes
-
-No binary breaking changes are allowed within a major version. Three patterns are used:
-
-### 5.1 Obsolete Constructor + StaticServiceProvider
-
-When a public class needs new dependencies, obsolete the existing constructor and add a new one. The old constructor delegates to the new one, resolving missing deps via `StaticServiceProvider`.
-
-```csharp
-[Obsolete("Please use the constructor with all parameters. Scheduled for removal in Umbraco 19.")]
-public MyService(IDependencyA depA)
-    : this(
-        depA,
-        StaticServiceProvider.Instance.GetRequiredService<IDependencyB>())
-{
-}
-
-public MyService(IDependencyA depA, IDependencyB depB)
-{
-    _depA = depA;
-    _depB = depB;
-}
-```
-
-**Examples**:
-- `ContentCollectionPresentationFactory` - added `FlagProviderCollection`
-- `CacheInstructionService` - added `ILastSyncedManager`, `IRepositoryCacheVersionService`
-- `DocumentPresentationFactory` - added `FlagProviderCollection`
-
-**Rules**:
-- Old constructor marked `[Obsolete("... Scheduled for removal in Umbraco {current-major+2}.")]`
-- Old constructor calls new constructor via `: this(...)`
-- Uses `StaticServiceProvider.Instance.GetRequiredService<T>()` for new params only
-- DI registration must use the NEW constructor (old is for external consumers only)
-
-### 5.2 Obsolete Method + New Overload
-
-When a public method signature needs to change, add the new method/overload and obsolete the old. The obsolete method should call the new one with suitable defaults.
-
-```csharp
-[Obsolete("Use the overload taking all parameters. Scheduled for removal in Umbraco 19.")]
-public void DoThing(string name)
-    => DoThing(name, extraParam: null);
-
-public void DoThing(string name, string? extraParam)
-{
-    // Real implementation here
-}
-```
-
-**Rules**:
-- Old method marked `[Obsolete]` with removal schedule
-- DRY: old method calls new method, providing defaults for new parameters
-- All internal callers must be updated to use the new method
-- No callers should remain on the obsolete method within the codebase
-
-### 5.3 Default Interface Implementation
-
-When adding methods to a public interface, provide a default implementation so existing external implementations don't break.
-
-```csharp
-public interface IMyService
-{
-    // Existing method
-    void ExistingMethod();
-
-    // New method with default implementation
-    void NewMethod(string param)
-        => ExistingMethod(); // delegate to existing if possible
-}
-```
-
-**Strategies for the default** (in order of preference):
-1. **Use existing interface methods** to satisfy the contract (even if not optimal)
-2. **Return a sensible default** like empty collection, null, etc.
-3. **Throw `NotImplementedException`** if no reasonable default exists
-
-**Example**: `IContentService.SaveBlueprint` - new overload with `IContent? createdFromContent` has a default impl that calls the old method (ignoring the new param).
-
-**Example**: `IDocumentPresentationFactory.CreateCulturePublishScheduleModels` - full default implementation with logic, uses `StaticServiceProvider` for dependency resolution within the interface.
-
-**Rules**:
-- Add `// TODO (V{next-major}): Remove the default implementation when {obsolete method} is removed.` comment
-- Default impl should be functionally correct even if not optimal
-- If using `StaticServiceProvider` in a default impl, note this is temporary
-
-### 5.4 General Rules
-
-- **Removal policy**: Obsoleted members must remain for at least one full major version before removal. If obsoleted in version N, the earliest removal is version N+2. For example, something obsoleted in v17 is scheduled for removal in v19 (giving the whole of v18 as a deprecation period).
-- All `[Obsolete]` attributes must include **"Scheduled for removal in Umbraco {current+2}"**
-- Read `version.json` to determine the current major version
-- Suppress `CS0618` warnings where obsolete members must call each other:
-  ```csharp
-  #pragma warning disable CS0618 // Type or member is obsolete
-      => OldMethod(param);
-  #pragma warning restore CS0618 // Type or member is obsolete
-  ```
-- Update ALL internal callers to use the new API - no internal code should use obsolete members
-
----
-
-## 6. Project-Specific Notes
-
-### Centralized Package Management
-
-**NuGet package versions** are centralized in `Directory.Packages.props`. There are two `Directory.Packages.props` files in the source tree, with multi-level merging enabled so the test file inherits from the root:
-
-| File | Scope |
-|------|-------|
-| `Directory.Packages.props` (root) | Production source code packages — referenced by all `src/**` projects |
-| `tests/Directory.Packages.props` | Test-only packages (NUnit, Moq, Bogus, BenchmarkDotNet, etc.) — adds entries on top of the inherited root file |
-
-When updating dependencies, decide which file the package belongs in:
-- A package used only by test projects → `tests/Directory.Packages.props`
-- A package used by any production project (or by both production and tests) → root `Directory.Packages.props`
-
-```xml
-<!-- Individual projects reference WITHOUT version -->
-<PackageReference Include="Microsoft.AspNetCore.OpenApi" />
-
-<!-- Versions defined in Directory.Packages.props -->
-<PackageVersion Include="Microsoft.AspNetCore.OpenApi" Version="10.0.0" />
-```
-
-**Opt-out**: `src/Umbraco.Web.UI/Umbraco.Web.UI.csproj` sets `<ManagePackageVersionsCentrally>false</ManagePackageVersionsCentrally>` and specifies versions inline (for `Microsoft.EntityFrameworkCore.Design`, `Microsoft.Build.Tasks.Core`, `Microsoft.ICU.ICU4C.Runtime`, etc.). Update those versions directly in that csproj when bumping. Two further `Directory.Packages.props` files exist under `templates/` for the project/extension templates and have their own version sets — keep `Microsoft.AspNetCore.OpenApi` aligned between the root file and `templates/UmbracoExtension/`.
-
-### Build Configuration
-
-- `Directory.Build.props` - Shared properties (target framework, company, copyright)
-- `.editorconfig` - Code style rules
-- `.globalconfig` - Roslyn analyzer rules
-
-### Persistence Layer - NPoco and EF Core
-
-The repository contains BOTH (actively supported):
-- **Current**: NPoco-based persistence (`Umbraco.Cms.Persistence.Sqlite`, `Umbraco.Cms.Persistence.SqlServer`) - widely used and fully supported
-- **Future**: EF Core-based persistence (`Umbraco.Cms.Persistence.EFCore.*`) - migration in progress
-
-**Note**: The codebase is actively migrating to EF Core, but NPoco remains the primary persistence layer and is not deprecated. Both are fully supported.
-
-### Authentication: OpenIddict
-
-All APIs use **OpenIddict** (OAuth 2.0/OpenID Connect):
-- Reference tokens (not JWT) for better security
-- **Secure cookie-based token storage** (v17+) - tokens stored in HTTP-only cookies with `__Host-` prefix
-- Tokens are redacted from client-side responses and passed via secure cookies only (`[redacted]` placeholder)
-- ASP.NET Core Data Protection for token encryption
-- Configured in `Umbraco.Cms.Api.Common`
-- API requests must include credentials (`credentials: include` for fetch)
-
-**Load Balancing Requirement**: All servers must share the same Data Protection key ring.
-
-**Frontend auth pitfalls** — see `src/Umbraco.Web.UI.Client/docs/edge-cases.md` (Auth & Cross-tab section) and `docs/security.md`. Key points:
-- Never call `validateToken()` per API request — it revokes the previous reference token (ID2019 errors)
-- `window.opener` is set for ANY `window.open()` target, not only OAuth popups — scope guards to the pathname too
-- BroadcastChannel does not deliver messages to the sender's own tab
-
-### Content Caching Strategy
-
-**HybridCache** (`Umbraco.PublishedCache.HybridCache`):
-- In-memory cache + distributed cache support
-- Published content only (not draft)
-- Invalidated via notifications and cache refreshers
-
-### API Versioning
-
-APIs use `Asp.Versioning.Mvc`:
-- Management API: `/umbraco/management/api/v{version}/*`
-- Delivery API: `/umbraco/delivery/api/v{version}/*`
-- OpenAPI docs: `/umbraco/openapi/management.json`, `/umbraco/openapi/delivery.json`
-- Swagger UI: `/umbraco/openapi/`
-
-### Updating `OpenApi.json` (Management API)
-
-When a PR changes Management API controllers or models, the `OpenApi.json` file in the Management API project must be updated:
-
-1. Run the Umbraco instance locally
-2. Open Swagger UI and navigate to the swagger.json link (e.g. `https://localhost:44339/umbraco/swagger/management/swagger.json`)
-3. Copy the full JSON content and paste it into `src/Umbraco.Cms.Api.Management/OpenApi.json`
-
-**Important**: Commit only the substantive changes — not IDE-applied formatting (whitespace, reordering, etc.). Extraneous formatting diffs make PRs harder to review and merge-ups more error-prone.
-
-### Backoffice npm Package
-
-The backoffice is published to npm as `@umbraco-cms/backoffice`. Runtime dependencies are provided via importmap; npm peerDependencies provide types only. For full details on dependency hoisting, version range logic, and plugin development, see `/src/Umbraco.Web.UI.Client/CLAUDE.md` → "npm Package Publishing".
-
-### Known Limitations
-
-1. **Circular Dependencies**: Avoided via `Lazy<T>` or event notifications
-2. **Multi-Server**: Requires shared Data Protection key ring and synchronized clocks (NTP)
-3. **Database Support**: SQL Server, SQLite

-## 7. CI/CD — Claude AI Assistant
-
-Two GitHub Actions workflows powered by `anthropics/claude-code-action@v1`. Advisory only — does not block merging.
-
-### Workflows
-
-| File | Trigger | Purpose |
-|------|---------|---------|
-| `claude-review.yml` | `pull_request: [opened, ready_for_review]` | Auto-review every non-draft PR using the `umb-review` skill |
-| `claude.yml` | `@claude` comments, issue assign/label | Interactive assistant for PRs and issues |
-
-### Auto-Review (`claude-review.yml`)
-
-Runs the full `.claude/skills/umb-review/SKILL.md` procedure on every newly opened or un-drafted PR. Produces inline comments per finding and one summary comment with a verdict. Skips draft PRs. No turn limit.
-
-### Interactive (`claude.yml`)
-
-Responds to `@claude` mentions on PRs and issues. The trigger phrase is stripped before Claude sees the message, so:
-
-- `@claude review` → light review using `gh pr diff` (not the umb-review skill)
-- `@claude fix ...` → implements a fix on a new branch
-- `@claude help` → answers questions about the codebase
-- `@claude label` → applies labels
-- `@claude` (empty) → defaults to `review` on PRs, `help` on issues
-
-Also triggers on issue assignment to `claude` or adding the `claude` label. Gated: only runs when `@claude` appears in the comment/issue body. Max 25 turns.
-
-**Allowed Bash tools**: `gh`, `git`, `npm`, `dotnet` (interactive only; auto-review allows `gh` and `git`).
-
-### Labels
-
-Both workflows apply labels based on content:
-
-**On PRs** (based on changed files):
-
-| Label | Condition |
-|-------|-----------|
-| `area/frontend` | Files under `src/Umbraco.Web.UI.Client/` |
-| `area/backend` | `.cs` files outside the frontend client |
-| `area/test` | Only test files changed |
-| `category/api` | Management or Delivery API files |
-| `category/breaking` | Breaking changes detected |
-| `category/localization` | Localization/language files |
-| `category/test-automation` | Only test files changed |
-| `category/refactor` | Pure refactoring, no new features |
-| `category/performance` | Performance-related changes |
-| `category/ux` | User-facing changes |
-| `category/ui` | UI layer changes |
-
-**On Issues** (based on content): same `area/*` and `category/*` labels, plus `affected/v14` through `affected/v17` and `affected/backoffice`.
-
-Labels are only added, never removed. Claude applies only labels it is confident about.
-
-### Key Implementation Notes
-
-- **Checkout required** — the action internally runs `git fetch origin main` for trusted file restoration. Without `actions/checkout`, it fails with `fatal: not a git repository`.
-- **`id-token: write` permission** — required for OIDC token exchange with the Claude GitHub App.
-- **Trigger phrase stripping** — the action strips `@claude` from comments before passing to Claude. Prompts must reference commands without the prefix (e.g., `review` not `@claude review`).
-- **PR number injection** — the interactive workflow injects the PR/issue number into the prompt via `${{ github.event.issue.number }}` since Claude can't discover it from `gh pr view` when checked out on `main`.
-
----
-
-## 8. Code Comment Policy
-
-**Default to no comment.** Applies to all code in this repository — C#, TypeScript, Razor, build scripts. Well-named identifiers and small functions are the primary form of self-documentation; comments are a fallback for the rare cases where the code itself cannot carry the meaning.
-
-### When NOT to comment
-
-- **Don't restate what the code does.** A line calling `resetState()` does not need `// Reset state`. A method named `validateInput` does not need `// Validate input`.
-- **Don't narrate a sequence of calls.** If three lines run in order, the order is in the code — don't paraphrase it above.
-- **Don't reference the current task, fix, callers, or PR.** No `// Fix for X`, `// Used by Y`, `// Added for the Z flow`, `// See PR #1234`. That belongs in commit messages and PR descriptions; in source it rots as the codebase evolves.
-
-### When a comment IS justified
-
-Write a comment only when **removing it would leave a future reader confused**. Concretely:
-
-- **A non-obvious WHY.** A hidden constraint, business rule, or ordering requirement that is not visible from the code.
-- **A workaround for a specific bug or platform quirk.** Link the issue (`(#21996)`, `https://...`) so the comment can be deleted once the upstream fix lands.
-- **A subtle invariant** that the type system or method names do not enforce.
-- **An edge case the code intentionally handles** that would surprise a reader (e.g. "must run before X because Y").
-- **API documentation** — XML doc comments on C# members, JSDoc on exported TypeScript symbols. Required for the public contract; still keep them concise.
-
-### TODOs
-
-Allowed, but cheap to write and cheaper to leave behind. Keep them short and trackable: `// TODO (V19): remove once obsolete overload is gone` or `// TODO: pagination [NL]`. A TODO should have an author or a version trigger.

-## Quick Reference
-
-### Essential Commands
-
-```bash
-# Build solution
-dotnet build
-
-# Run all tests
-dotnet test
-
-# Run specific test category
-dotnet test --filter "Category=Integration"
-
-# Format code
-dotnet format
-
-# Pack all projects
-dotnet pack -c Release
-```
-
-### Integration Test Database Configuration
-
-Integration tests are configured in `tests/Umbraco.Tests.Integration/appsettings.Tests.json`.
-
-The `Tests:Database:DatabaseType` setting controls which database is used:
-- `"SQLite"` (default) - No external dependencies
-- `"LocalDb"` - Uses SQL Server LocalDB, required for SQL Server-specific tests (e.g., page-level locking, `sys.dm_tran_locks`)
-
-SQL Server-specific tests use `BaseTestDatabase.IsSqlite()` to skip when running on SQLite.

-### Project-Specific Documentation
-
-For detailed information about individual projects, see their CLAUDE.md files:
-- **Core Architecture**: `/src/Umbraco.Core/CLAUDE.md` - Service contracts, notification patterns
-- **API Infrastructure**: `/src/Umbraco.Cms.Api.Common/CLAUDE.md` - OpenAPI, authentication, serialization
-- **Backoffice Frontend**: `/src/Umbraco.Web.UI.Client/CLAUDE.md` - Lit web components, extension system, auth client
-
-**Important**: When working on backoffice client code (anything under `src/Umbraco.Web.UI.Client/`), read `/src/Umbraco.Web.UI.Client/CLAUDE.md` first. It contains action-specific checklists (deprecation, testing, security, etc.) that are not duplicated here.

-# MCP (Model Context Protocol) Setup
-
-This repository includes configuration for [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) servers, enabling AI tooling integration for Umbraco CMS development workflows.
-
-## Overview
-
-MCP allows AI assistants (like Claude) to interact with external tools and services. This repository configures two MCP servers:
-
-| Server | Purpose | Package |
-|--------|---------|---------|
-| **umbraco-cms** | Manage Umbraco content types, documents, and media | `@umbraco-cms/mcp-dev@17` |
-| **playwright** | Browser automation for testing and debugging | `@playwright/mcp@latest` |
-
-## Quick Start
-
-### 1. Start Umbraco Locally
-
-Ensure your local Umbraco instance is running at `https://localhost:44339` (or update the URL in your `.env.local`).
-
-### 2. Configure Environment Variables
-
-Copy the example environment file and customize it:
-
-```bash
-cp .env.example .env.local
-```
-
-Edit `.env.local` with your local settings:
-
-```env
-UMBRACO_CLIENT_ID=umbraco-back-office-mcp
-UMBRACO_CLIENT_SECRET=<your-client-secret>
-UMBRACO_BASE_URL=https://localhost:44339
-NODE_TLS_REJECT_UNAUTHORIZED=0
-UMBRACO_INCLUDE_TOOL_COLLECTIONS=data-type,document-type,document,media-type,media
-```
-
-### 3. Configure the OAuth Client in Umbraco
-
-Create an OAuth client in your Umbraco instance with:
-- **Client ID**: `umbraco-back-office-mcp`
-- **Client Secret**: The value you set in `.env.local`
-- **Grant Type**: Client Credentials
-
-## Environment Variables Reference
-
-| Variable | Description | Example |
-|----------|-------------|---------|
-| `UMBRACO_CLIENT_ID` | OAuth client ID configured in Umbraco | `umbraco-back-office-mcp` |
-| `UMBRACO_CLIENT_SECRET` | OAuth client secret (keep secure!) | `your-secure-secret` |
-| `UMBRACO_BASE_URL` | URL of your local Umbraco instance | `https://localhost:44339` |
-| `NODE_TLS_REJECT_UNAUTHORIZED` | Set to `0` for self-signed certificates (local dev only) | `0` |
-| `UMBRACO_INCLUDE_TOOL_COLLECTIONS` | Comma-separated list of tool collections to enable | `data-type,document-type,document` |
-
-### Tool Collections
-
-The `UMBRACO_INCLUDE_TOOL_COLLECTIONS` variable controls which Umbraco MCP tools are available:
-
-- `data-type` - Manage data types (property editors)
-- `document-type` - Manage document types (content types)
-- `document` - Manage content/documents
-- `media-type` - Manage media types
-- `media` - Manage media items
-
-## Security Considerations
-
-> **Warning**: This configuration is for **local development only**.
-
-### Self-Signed Certificates
-
-`NODE_TLS_REJECT_UNAUTHORIZED=0` disables SSL certificate validation. This is necessary for self-signed certificates in local development but:
-
-- **Never use in production**
-- Affects all HTTPS connections made by Node.js processes
-- Consider trusting your local development certificate instead
-
-### Client Secrets
-
-- Never commit real secrets to source control
-- The `.env.local` file is gitignored for this reason
-- Use strong, unique secrets even in development
-- The example value `1234567890` in `.env.example` is a placeholder only
-
-## File Structure
-
-```
-Umbraco-CMS/
-├── .mcp.json              # MCP server configuration
-├── .env.example           # Example environment variables (committed)
-├── .env.local             # Your local environment variables (gitignored)
-├── .claude/
-│   ├── settings.json      # Shared Claude AI permissions (committed)
-│   └── settings.local.json # Local Claude overrides (gitignored)
-├── .gitignore             # Ignores .env.local and settings.local.json
-└── MCP.md                 # This documentation (you are here)
-```
-
-## Claude AI Permissions
-
-The `.claude/settings.json` file configures which MCP tools Claude can use automatically without prompting. This is shared across the team for consistent developer experience.
-
-### Customizing Permissions Locally
-
-Create `.claude/settings.local.json` to override permissions for your environment:
-
-```json
-{
-  "permissions": {
-    "allow": [
-      "mcp__umbraco__get-all-document-types"
-    ]
-  }
-}
-```
-
-## Troubleshooting
-
-### "Connection refused" errors
-
-- Ensure Umbraco is running at the configured `UMBRACO_BASE_URL`
-- Check that the port matches your local setup
-
-### "Unauthorized" errors
-
-- Verify the OAuth client is configured in Umbraco
-- Check that `UMBRACO_CLIENT_ID` and `UMBRACO_CLIENT_SECRET` match
-- Ensure the client has appropriate permissions
-
-### "Certificate" errors
-
-- For local development, set `NODE_TLS_REJECT_UNAUTHORIZED=0` in `.env.local`
-- Alternatively, trust your local development certificate
-
-### MCP server not starting
-
-- Ensure Node.js is installed (v22+ recommended, matching .nvmrc)
-- Run `npx @umbraco-cms/mcp-dev@17 --help` to verify the package works

-
-### Design Patterns
-
-1. **Builder Pattern** - `ProblemDetailsBuilder` for fluent error responses
-2. **Options Pattern** - All configuration via `IConfigureOptions<T>`
-
----
-
-## 2. Commands
-
-See "Quick Reference" section at bottom for common commands.
-
----
-
-## 3. Key Patterns
-
-### Schema ID Generation (OpenApi/UmbracoSchemaIdGenerator.cs)
-
-Static utility class that generates OpenAPI schema IDs following Umbraco's naming conventions:
-
-```csharp
-// Add "Model" suffix to avoid TypeScript name clashes
-if (name.EndsWith("Model") == false)
-{
-    // because some models names clash with common classes in TypeScript (i.e. Document),
-    // we need to add a "Model" postfix to all models
-    name = $"{name}Model";
-}
-
-// Remove invalid characters to prevent OpenAPI generation errors
-return Regex.Replace(name, @"[^\w]", string.Empty);
-```
-
-**Generic Type Handling**: `PagedViewModel<RelationItemViewModel>` becomes `PagedRelationItemModel`
-
-### Polymorphic Deserialization (Serialization/UmbracoJsonTypeInfoResolver.cs:29-35)
-
-```csharp
-// IMPORTANT: do NOT return an empty enumerable here. it will cause nullability to fail on reference
-// properties, because "$ref" does not mix and match well with "nullable" in OpenAPI.
-if (type.IsInterface is false)
-{
-    return new[] { type };
-}
-```
-
-**Why**: Interfaces must return concrete types to avoid OpenAPI schema conflicts.
-
----
-
-## 4. Testing
-
-**Location**: No direct tests - tested via integration tests in consuming APIs
-
-**How to test changes**:
-```bash
-# Run integration tests that exercise this library
-dotnet test tests/Umbraco.Tests.Integration/
-
-# Verify OpenAPI generation
-# 1. Run the application: dotnet run --project src/Umbraco.Web.UI
-# 2. Navigate to /umbraco/openapi/ for Swagger UI
-# 3. Check schema IDs and operation IDs
-# OpenAPI JSON documents available at:
-#   - /umbraco/openapi/management.json (Management API)
-#   - /umbraco/openapi/delivery.json (Delivery API)
-```
-
-**Focus areas when testing**:
-- OpenAPI document generation (schema IDs, operation IDs)
-- Polymorphic JSON serialization/deserialization
-- OpenIddict authentication flow
-- Problem details formatting
-
----
-
-## 5. OpenIddict Authentication
-
-### Key Configuration (DependencyInjection/UmbracoBuilderAuthExtensions.cs)
-
-**Reference Tokens over JWT** (line 76-80):
-```csharp
-// Enable reference tokens
-// - see https://documentation.openiddict.com/configuration/token-storage.html
-options
-    .UseReferenceAccessTokens()
-    .UseReferenceRefreshTokens();
-```
-
-**Why**: More secure (revocable), better for load balancing, uses ASP.NET Core Data Protection.
-
-**Token Lifetime** (line 88-91):
-```csharp
-// Make the access token lifetime 25% of the refresh token lifetime
-options.SetAccessTokenLifetime(new TimeSpan(timeOut.Ticks / 4));
-options.SetRefreshTokenLifetime(timeOut);
-```
-
-**PKCE Required** (line 59-63):
-```csharp
-// Enable authorization code flow with PKCE
-options
-    .AllowAuthorizationCodeFlow()
-    .RequireProofKeyForCodeExchange()
-    .AllowRefreshTokenFlow();
-```
-
-**Endpoints**: Backoffice `/umbraco/management/api/v1/security/*`, Member `/umbraco/member/api/v1/security/*`
-
-### Secure Cookie-Based Token Storage (v17+)
-
-**Implementation** (DependencyInjection/HideBackOfficeTokensHandler.cs):
-
-Back-office tokens are hidden from client-side JavaScript via HTTP-only cookies:
-
-```csharp
-private const string AccessTokenCookieKey = "__Host-umbAccessToken";
-private const string RefreshTokenCookieKey = "__Host-umbRefreshToken";
-
-// Tokens are encrypted via Data Protection and stored in cookies
-SetCookie(httpContext, AccessTokenCookieKey, context.Response.AccessToken);
-context.Response.AccessToken = "[redacted]";  // Client sees redacted value
-```
-
-**Key Security Features** (lines 143-165): `HttpOnly`, `IsEssential`, `Path="/"`, `Secure` (HTTPS), `__Host-` prefix
-
-**Configuration**: `BackOfficeTokenCookieSettings.Enabled` (default: true in v17+)
-
-**Implications**: Client-side cannot access tokens; encrypted with Data Protection; load balancing needs shared key ring; API requests need `credentials: include`
-
----
-
-## 6. Common Issues & Edge Cases
-
-### Polymorphic Deserialization Requires `$type`
-
-**Issue**: Deserializing to an interface without `$type` discriminator fails.
-
-**Handled in** (Json/NamedSystemTextJsonInputFormatter.cs:24-29):
-```csharp
-catch (NotSupportedException exception)
-{
-    // This happens when trying to deserialize to an interface, without sending the $type as part of the request
-    context.ModelState.TryAddModelException(string.Empty, new InputFormatterException(exception.Message, exception));
-    return await InputFormatterResult.FailureAsync();
-}
-```
-
-**Solution**: Clients must include `$type` property for interface types, or use concrete types.
-
-### Schema ID Collisions with TypeScript
-
-**Issue**: Type names like `Document` clash with TypeScript built-ins.
-
-**Solution**: `UmbracoSchemaIdGenerator` adds "Model" suffix to all schema names.
-
-### Generic Type Handling
-
-**Issue**: `PagedViewModel<T>` needs flattened schema name.
-
-**Solution**: `UmbracoSchemaIdGenerator.Generate()` flattens generic types:
-- `PagedViewModel<RelationItemViewModel>` becomes `PagedRelationItemModel`
-
----
-
-## 7. Extending This Library
-
-### Adding Custom OpenAPI Transformers
-
-OpenAPI transformers are scoped per-document. To customize a document, implement `IOpenApiDocumentTransformer`, `IOpenApiOperationTransformer`, or `IOpenApiSchemaTransformer` and register with your OpenAPI options.
-
-For schema ID generation, use the static `UmbracoSchemaIdGenerator.Generate(Type)` method.
-
-### Customizing Problem Details
-
-```csharp
-var problemDetails = new ProblemDetailsBuilder()
-    .WithTitle("Validation Failed")
-    .WithDetail("The request contains errors")
-    .WithType("ValidationError")
-    .WithOperationStatus(MyOperationStatus.ValidationFailed)
-    .WithRequestModelErrors(errors)
-    .Build();
-
-return BadRequest(problemDetails);
-```
-
----
-
-## 8. Project-Specific Notes
-
-### Per-Document Transformer Scoping
-
-With Microsoft.AspNetCore.OpenApi, transformers are configured per OpenAPI document. This means custom transformers only apply to the documents they're registered with, not globally. Each API (Management, Delivery) configures its own transformers via `ConfigureUmbracoOpenApiOptionsBase` subclasses.
-
-### Performance: Subtype Caching
-
-**Why**: Cache discovered subtypes (UmbracoJsonTypeInfoResolver.cs:14) to avoid expensive reflection calls
-
-### Known Limitations
-
-1. **Polymorphic Deserialization**:
-   - Requires `$type` discriminator in JSON for interfaces
-   - Only discovers types in Umbraco namespaces
-   - Not all .NET types are discoverable
-
-2. **OpenAPI Schema Generation**:
-   - Generic types are flattened (e.g., `PagedViewModel<T>` → `PagedTModel`)
-   - Type names may need "Model" suffix to avoid clashes
-
-3. **OpenIddict Multi-Server**:
-   - Requires shared Data Protection key ring
-   - All servers must have synchronized clocks (NTP)
-   - Reference tokens require database storage
-
-### External Dependencies
-
-**OpenIddict**:
-- OAuth 2.0 / OpenID Connect provider
-- Version: See `Directory.Packages.props`
-- Uses ASP.NET Core Data Protection for token encryption
-
-**Microsoft.AspNetCore.OpenApi**:
-- OpenAPI 3.1.1 document generation
-- Custom transformers: `SchemaIdTransformer`, `OperationIdTransformer`, `MimeTypeDocumentTransformer`, `ServerTransformer`
-
-**Swashbuckle.AspNetCore.SwaggerUI**:
-- Swagger UI for browsing and testing API endpoints
-- Accessed at `/umbraco/openapi/`
-
-**Asp.Versioning**:
-- API versioning via `ApiVersion` attribute
-- API explorer integration for multi-version Swagger docs
-
-### Configuration
-
-**HTTPS**: `DisableTransportSecurityRequirement` for local dev only (ConfigureOpenIddict.cs:14). **Warning**: Never disable in production.
-
-### Usage Pattern
-
-Consuming APIs call `builder.AddUmbracoOpenApi().AddUmbracoOpenIddict()`
