 *   **Naming Conventions:**
     *   **Python:** Follows PEP 8. Use clear, descriptive names following snake_case.
-    *   **C++:** Follows the Google C++ Style Guide with these specifics (following clang-tidy conventions):
-        - Function, method, and variable names: `lower_snake_case`
-        - Class/struct/enum names: `UpperCamelCase`
-        - Top-level constants (global/namespace scope): `UPPER_SNAKE_CASE`
-        - Function-local constants: `lower_snake_case`
-        - Protected/private fields: `lower_snake_case_with_trailing_underscore_`
-        - Favor descriptive names over abbreviations
-
-*   **C++ Field Visibility:**
-    *   **Prefer `protected`:** Use `protected` for most class fields to enable extensibility and testing. Fields should be `lower_snake_case_with_trailing_underscore_`.
-    *   **Use `private` for safety-critical cases:** Use `private` visibility when direct field access could introduce bugs or violate invariants:
-        1. **Pointer lifetime issues:** When setters validate and store pointers from known lists to prevent dangling references.
-           ```cpp
-           // Helper to find matching string in vector and return its pointer
-           inline const char *vector_find(const std::vector<const char *> &vec, const char *value) {
-             for (const char *item : vec) {
-               if (strcmp(item, value) == 0)
-                 return item;
-             }
-             return nullptr;
-           }
-
-           class ClimateDevice {
-            public:
-             void set_custom_fan_modes(std::initializer_list<const char *> modes) {
-               this->custom_fan_modes_ = modes;
-               this->active_custom_fan_mode_ = nullptr;  // Reset when modes change
-             }
-             bool set_custom_fan_mode(const char *mode) {
-               // Find mode in supported list and store that pointer (not the input pointer)
-               const char *validated_mode = vector_find(this->custom_fan_modes_, mode);
-               if (validated_mode != nullptr) {
-                 this->active_custom_fan_mode_ = validated_mode;
-                 return true;
-               }
-               return false;
-             }
-            private:
-             std::vector<const char *> custom_fan_modes_;  // Pointers to string literals in flash
-             const char *active_custom_fan_mode_{nullptr};  // Must point to entry in custom_fan_modes_
-           };
-           ```
-        2. **Invariant coupling:** When multiple fields must remain synchronized to prevent buffer overflows or data corruption.
-           ```cpp
-           class Buffer {
-            public:
-             void resize(size_t new_size) {
-               auto new_data = std::make_unique<uint8_t[]>(new_size);
-               if (this->data_) {
-                 std::memcpy(new_data.get(), this->data_.get(), std::min(this->size_, new_size));
-               }
-               this->data_ = std::move(new_data);
-               this->size_ = new_size;  // Must stay in sync with data_
-             }
-            private:
-             std::unique_ptr<uint8_t[]> data_;
-             size_t size_{0};  // Must match allocated size of data_
-           };
-           ```
-        3. **Resource management:** When setters perform cleanup or registration operations that derived classes might skip.
-    *   **Provide `protected` accessor methods:** When derived classes need controlled access to `private` members.
-
-*   **C++ Preprocessor Directives:**
-    *   **Avoid `#define` for constants:** Using `#define` for constants is discouraged and should be replaced with `const` variables or enums.
-    *   **Use `#define` only for:**
-        - Conditional compilation (`#ifdef`, `#ifndef`)
-        - Compile-time sizes calculated during Python code generation (e.g., configuring `std::array` or `StaticVector` dimensions via `cg.add_define()`)
-
-*   **C++ Additional Conventions:**
-    *   **Member access:** Prefix all class member access with `this->` (e.g., `this->value_` not `value_`)
-    *   **Indentation:** Use spaces (two per indentation level), not tabs
-    *   **Type aliases:** Prefer `using type_t = int;` over `typedef int type_t;`
-    *   **Line length:** Wrap lines at no more than 120 characters
+    *   **C++:** Follows the Google C++ Style Guide.

 ## 7. Specific Instructions for AI Collaboration
 
 *   **Contribution Workflow (Pull Request Process):**
-    1.  **Fork & Branch:** Create a new branch based on the `dev` branch (always use `git checkout -b <branch-name> dev` to ensure you're branching from `dev`, not the currently checked out branch).
+    1.  **Fork & Branch:** Create a new branch in your fork.
     2.  **Make Changes:** Adhere to all coding conventions and patterns.
     3.  **Test:** Create component tests for all supported platforms and run the full test suite locally.
     4.  **Lint:** Run `pre-commit` to ensure code is compliant.
     5.  **Commit:** Commit your changes. There is no strict format for commit messages.
-    6.  **Pull Request:** Submit a PR against the `dev` branch. The Pull Request title should have a prefix of the component being worked on (e.g., `[display] Fix bug`, `[abc123] Add new component`). Update documentation, examples, and add `CODEOWNERS` entries as needed. Pull requests should always be made using the `.github/PULL_REQUEST_TEMPLATE.md` template - fill out all sections completely without removing any parts of the template.

-        CORE.data[MY_FEATURE_KEY] = True

-        DOMAIN = "my_component"

-        If you need a real-world example, search for components that use `@dataclass` with `CORE.data` in the codebase. Note: Some components may use `TypedDict` for dictionary-based storage; both patterns are acceptable depending on your needs.
-
         **Why this matters:**
         - Module-level globals persist between compilation runs if the dashboard doesn't fork/exec
         - `CORE.data` automatically clears between runs
-        - Namespacing under `DOMAIN` prevents key collisions between components
-        - `@dataclass` provides type safety and cleaner attribute access
+        - Typed helper functions provide better IDE support and maintainability
+        - Encapsulation makes state management explicit and testable
 
 *   **Security:** Be mindful of security when making changes to the API, web server, or any other network-related code. Do not hardcode secrets or keys.

-## 8. Public API and Breaking Changes
-
-*   **Public C++ API:**
-    *   **Components**: Only documented features at [esphome.io](https://esphome.io) are public API. Undocumented `public` members are internal.
-    *   **Core/Base Classes** (`esphome/core/`, `Component`, `Sensor`, etc.): All `public` members are public API.
-    *   **Components with Global Accessors** (`global_api_server`, etc.): All `public` members are public API (except config setters).
-
-*   **Public Python API:**
-    *   All documented configuration options at [esphome.io](https://esphome.io) are public API.
-    *   Python code in `esphome/core/` actively used by existing core components is considered stable API.
-    *   Other Python code is internal unless explicitly documented for external component use.
-
-*   **Breaking Changes Policy:**
-    *   Aim for **6-month deprecation window** when possible
-    *   Clean breaks allowed for: signature changes, deep refactorings, resource constraints
-    *   Must document migration path in PR description (generates release notes)
-    *   Blog post required for core/base class changes or significant architectural changes
-    *   Full details: https://developers.esphome.io/contributing/code/#public-api-and-breaking-changes
-
-*   **Breaking Change Checklist:**
-    - [ ] Clear justification (RAM/flash savings, architectural improvement)
-    - [ ] Explored non-breaking alternatives
-    - [ ] Added deprecation warnings if possible (use `ESPDEPRECATED` macro for C++)
-    - [ ] Documented migration path in PR description with before/after examples
-    - [ ] Updated all internal usage and esphome-docs
-    - [ ] Tested backward compatibility during deprecation period
-
-*   **Deprecation Pattern (C++):**
-    ```cpp
-    // Remove before 2026.6.0
-    ESPDEPRECATED("Use new_method() instead. Removed in 2026.6.0", "2025.12.0")
-    void old_method() { this->new_method(); }
-    ```
-
-*   **Deprecation Pattern (Python):**
-    ```python
-    # Remove before 2026.6.0
-    if CONF_OLD_KEY in config:
-        _LOGGER.warning(f"'{CONF_OLD_KEY}' deprecated, use '{CONF_NEW_KEY}'. Removed in 2026.6.0")
-        config[CONF_NEW_KEY] = config.pop(CONF_OLD_KEY)  # Auto-migrate
-    ```
