+# Changelog page architecture
+
+This document describes the architecture of the Changelog page implementation in the `site/` directory.
+
+## Overview
+
+The Changelog page is a **hybrid static/dynamic** page. It renders all content
+statically on the server (SSG) for SEO and fast initial load, but includes a
+client-side JavaScript layer to handle interactive filtering and searching
+without requiring page reloads or server round-trips.
+
+## Key components
+
+### 1. Data model (`ChangelogEntry`)
+
++   **Location**: `site/lib/src/models/changelog_model.dart`
+
++   **Purpose**: Represents a single changelog item (version, date, area,
+    description, tags, etc.).
+
++   **Dual Parsing**:
+
+    +   **Server-side**: Parsed from the page's data map
+        (`context.page.data['changelog']`).
+
+    +   **Client-side**: Parsed *back* from the rendered HTML DOM elements using
+        `data-` attributes.
+
+### 2. Main page (`ChangelogIndex`)
+
++   **Location**: `site/lib/src/components/pages/changelog/changelog_index.dart`
+
++   **Type**: Stateless Server Component.
+
++   **Responsibility**:
+
+    +   Receives the raw changelog data.
+
+    +   Renders the initial HTML structure, including the sidebar and the list
+        of entries.
+
+    +   **Crucial Step**: Renders each entry as a `_ChangelogEntryCard` which
+        embeds the entry's data into HTML `data-` attributes (e.g.,
+        `data-version`, `data-area`, `data-tags`). This allows the client-side
+        script to "read" the data without needing a separate JSON payload.
+
+### 3. Filtering logic (`ChangelogFilters` & `ChangelogFiltersSidebar`)
+
++   **Location**:
+
+    +   `site/lib/src/components/pages/changelog/changelog_filters.dart`
+
+    +   `site/lib/src/components/pages/changelog/changelog_filters_sidebar.dart`
+
+    +   `site/lib/src/components/common/client/filtering.dart` (Shared UI
+        components: `CheckboxFilterGroup`, `CollapsibleFilterGroup`,
+        `FilterToolbar`)
+
++   **Type**: Client Components (`@client`).
+
++   **Responsibility**:
+
+    +   **Hydration**: On load, `ChangelogFilters` scans the DOM for
+        `.changelog-card` elements and reconstructs the list of `ChangelogEntry`
+        objects.
+
+    +   **State Management**: `ChangelogFiltersNotifier` (a singleton-like
+        notifier) manages the state of selected filters (tags, areas, versions)
+        and the search query.
+
+        +   **SSR Safety**: To prevent state leaks between requests during
+            development or static generation, `ChangelogIndex` calls
+            `disposeState()` on the notifier at the start of the build.
+
+        +   **Initialization**: `ChangelogFiltersSidebar` initializes the
+            available filters (by scanning the DOM) inside `initState` using
+            `addPostFrameCallback`. This ensures that DOM access only happens on
+            the client, preventing "Scheduling a frame" errors during
+            server-side rendering.
+
+    +   **Interaction**:
+
+        +   The **Sidebar** updates the notifier when checkboxes are toggled.
+
+        +   The **Search Bar** updates the notifier when text is typed.
+
+    +   **Rendering Updates**: When the notifier changes, `ChangelogFilters`
+        calculates which entries match the criteria and toggles the `hidden` CSS
+        class on the corresponding DOM elements.
+
+## Data flow
+
+1.  **Build Time**:
+
+    +   Changelog data is read from source (e.g., YAML/Markdown).
+
+    +   `ChangelogIndex` iterates over this data.
+
+    +   HTML is generated with all entries visible by default.
+
+    +   Data is serialized into `data-` attributes on each card.
+
+2.  **Client Load**:
+
+    +   The browser loads the static HTML.
+
+    +   `ChangelogFilters` component initializes.
+
+    +   It queries `document.getElementById('all-changelog-list')`.
+    +   It reads all children, parsing the `data-` attributes to build an
+        in-memory list of `ChangelogEntry` objects.
+
+    +   `ChangelogFiltersSidebar` also scans the DOM to populate the "Available
+        Filters" lists (e.g., finding all unique "Areas" present on the page).
+
+3.  **User Interaction (Filtering)**:
+
+    +   User clicks a checkbox (e.g., "Area: Language").
+
+    +   `ChangelogFiltersNotifier` updates its state.
+
+    +   `ChangelogFilters` listener fires.
+
+    +   It iterates through its in-memory entries, checking if they match the
+        new filters.
+
+    +   It updates the DOM: `element.classList.remove('hidden')` for matches,
+        `add('hidden')` for non-matches.
+
+## Benefits of this approach
+
++   **SEO Friendly**: All content is visible in the initial HTML.
+
++   **Performance**: No API calls are needed for filtering. The "database" is
+    the DOM itself.
+
++   **Simplicity**: No complex state synchronization between server and client;
+    the server just renders HTML, and the client treats that HTML as its source
+    of truth.
+
+## Managing changelog entries
+
+All changelog data is stored in a single YAML file. To add, edit, or remove
+entries, you will modify this file directly.
+
+### File location
+
+`src/data/changelog.yml`
+
+### Entry structure
+
+Each entry is a YAML list item with the following fields:
+
+```yaml
+- version: 3.10.0          # (Required) The SDK version number
+  releaseDate: 2025-11-12  # (Optional) YYYY-MM-DD or "TBD"
+  area: Language           # (Required) Broad category: SDK, Language, Libraries, Tools
+  subArea: Null safety     # (Optional) Specific feature or library name
+  description: |           # (Required) Multiline description of the change.
+    Null safety is now assumed...
+    Supports Markdown.
+  tags:                    # (Required) List of tags
+    - versioned
+    - changed
+  link: /path/to/docs      # (Optional) URL to further documentation or issue
+```
+
+### Common tasks
+
+#### Add an entry
+
+1.  Open `src/data/changelog.yml`.
+
+2.  Find the section corresponding to the relevant version (entries are 
+    typically ordered by version, descending).
+
+3.  Copy an existing entry block (including the separator comment
+    `# --------------------------------------------------`).
+
+4.  Paste it at the appropriate location.
+
+5.  Update the fields with the new information.
+
+#### Edit an entry
+
+1.  Open `src/data/changelog.yml`.
+
+2.  Search for the entry using keywords from its description or its
+    version number.
+
+3.  Modify the desired fields.
+
+4.  Save the file. The site will rebuild with the updated content.
+
+#### Delete an entry
+
+1.  Open `src/data/changelog.yml`.
+
+2.  Locate the entry block you wish to remove.
+
+3.  Delete the entire block, including the key-value pairs and the separator
+    comment above it.
+
+### Available tags
+
++   `new`: New feature added.
+
++   `breaking`: Breaking change.
+
++   `fixed`: Bug fix.
+
++   `changed`: Behavior change.
+
++   `experimental`: Experimental feature.
+
++   `versioned`: Language versioned change.
+
++   `deprecated`: Feature deprecated.
+
++   `removed`: Feature removed.
+
+## Builder guide: locating content
+
+This section provides instructions for builders on how to find and
+verify content on the Changelog page.
+
+### Source of truth
+
+The **absolute source of truth** for all changelog content is the YAML file:
+`src/data/changelog.yml`
+
+**Do not** try to parse the generated HTML or Dart code to find the *content*
+of a changelog entry. Always read the YAML file.
+
+### Find specific entries
+
+To find an entry for a specific version or feature:
+
+1.  **Read** `src/data/changelog.yml`.
+
+2.  **Search** the file content.
+
+    +   **By Version**: Search for `version: <number>`
+        (e.g., `version: 3.10.0`).
+
+    +   **By Keyword**: Search for keywords in the `description` field.
+
+    +   **By Area**: Filter mental results by the `area` field
+        (e.g., `area: Language`).
+
+### Verify rendering (if asked to check the UI)
+
+If you need to verify that an entry is *displayed* correctly on the site:
+
+1.  **Understand the Mapping**:
+
+    +   `version` -> Displayed prominently as a header or badge.
+
+    +   `area` -> Used for filtering and often displayed as a tag or
+        section header.
+
+    +   `description` -> Rendered as Markdown.
+
+    +   `tags` -> Rendered as colored badges (e.g., "Breaking", "New").
+
+2.  **Check the Component**:
+
+    +   The rendering logic is in `site/lib/src/components/pages/changelog/changelog_index.dart`.
+
+    +   Look for `_ChangelogEntryCard` to see how the YAML data is mapped to
+        HTML.
+
+3.  **Browser Verification**:
+
+    +   If you have browser access, navigate to `/changelog`.
+
+    +   Use `document.querySelectorAll('.changelog-card')` to find entries.
+
+    +   Check `dataset` attributes (e.g., `el.dataset.version`) to find the
+        specific entry you are looking for.

+    Dart 3.10 introduces dot shorthands for enums and other static members,
+    allowing you to omit the type name when the context makes it clear. It also
+    improves type inference for `sync*` and `async*` generator functions,
+    eliminating spurious `null` from their return types. The analyzer now
+    supports a new plugin system for custom rules and quick fixes, and several
+    new lints and assists have been added. Additionally, the Dart CLI has been
+    split from the Dart VM into a separate executable.

+    `sync*` and `async*` generator functions without a specified return now
+    correctly infer return types as non-nullable when no `null` value is

+    elements, such as an unnecessary null-aware access operator (`?.`).

+  description: |
+    Expanded type promotion to work on private final fields. Previously only
+    available for local variables and parameters, now private final fields can
+    promote to non-nullable types through null checks and `is` tests. For
+    example, the following code is now sound:
+
+    ```dart
+    class Example {
+      final int? _privateField;
+    
+      Example(this._privateField);
+    
+      void f() {
+        if (_privateField != null) {
+          // _privateField has now been promoted; you can use it without
+          // null checking it.
+          int i = _privateField; // OK
+        }
+      }
+    }
+    
+    // Private field promotions also work from outside of the class:
+    void f(Example x) {
+      if (x._privateField != null) {
+        int i = x._privateField; // OK
+      }
+    }
+    ```
