 *   **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

+    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.

     *   **Component Development:** Keep dependencies minimal, provide clear error messages, and write comprehensive docstrings and tests.
     *   **Code Generation:** Generate minimal and efficient C++ code. Validate all user inputs thoroughly. Support multiple platform variations.
     *   **Configuration Design:** Aim for simplicity with sensible defaults, while allowing for advanced customization.
-    *   **Embedded Systems Optimization:** ESPHome targets resource-constrained microcontrollers. Be mindful of flash size and RAM usage.
-
-        **STL Container Guidelines:**
-
-        ESPHome runs on embedded systems with limited resources. Choose containers carefully:
-
-        1. **Compile-time-known sizes:** Use `std::array` instead of `std::vector` when size is known at compile time.
-           ```cpp
-           // Bad - generates STL realloc code
-           std::vector<int> values;
-
-           // Good - no dynamic allocation
-           std::array<int, MAX_VALUES> values;
-           ```
-           Use `cg.add_define("MAX_VALUES", count)` to set the size from Python configuration.
-
-           **For byte buffers:** Avoid `std::vector<uint8_t>` unless the buffer needs to grow. Use `std::unique_ptr<uint8_t[]>` instead.
-
-           > **Note:** `std::unique_ptr<uint8_t[]>` does **not** provide bounds checking or iterator support like `std::vector<uint8_t>`. Use it only when you do not need these features and want minimal overhead.
-
-           ```cpp
-           // Bad - STL overhead for simple byte buffer
-           std::vector<uint8_t> buffer;
-           buffer.resize(256);
-
-           // Good - minimal overhead, single allocation
-           std::unique_ptr<uint8_t[]> buffer = std::make_unique<uint8_t[]>(256);
-           // Or if size is constant:
-           std::array<uint8_t, 256> buffer;
-           ```
-
-        2. **Compile-time-known fixed sizes with vector-like API:** Use `StaticVector` from `esphome/core/helpers.h` for fixed-size stack allocation with `push_back()` interface.
-           ```cpp
-           // Bad - generates STL realloc code (_M_realloc_insert)
-           std::vector<ServiceRecord> services;
-           services.reserve(5);  // Still includes reallocation machinery
-
-           // Good - compile-time fixed size, stack allocated, no reallocation machinery
-           StaticVector<ServiceRecord, MAX_SERVICES> services;  // Allocates all MAX_SERVICES on stack
-           services.push_back(record1);  // Tracks count but all slots allocated
-           ```
-           Use `cg.add_define("MAX_SERVICES", count)` to set the size from Python configuration.
-           Like `std::array` but with vector-like API (`push_back()`, `size()`) and no STL reallocation code.
-
-        3. **Runtime-known sizes:** Use `FixedVector` from `esphome/core/helpers.h` when the size is only known at runtime initialization.
-           ```cpp
-           // Bad - generates STL realloc code (_M_realloc_insert)
-           std::vector<TxtRecord> txt_records;
-           txt_records.reserve(5);  // Still includes reallocation machinery
-
-           // Good - runtime size, single allocation, no reallocation machinery
-           FixedVector<TxtRecord> txt_records;
-           txt_records.init(record_count);  // Initialize with exact size at runtime
-           ```
-           **Benefits:**
-           - Eliminates `_M_realloc_insert`, `_M_default_append` template instantiations (saves 200-500 bytes per instance)
-           - Single allocation, no upper bound needed
-           - No reallocation overhead
-           - Compatible with protobuf code generation when using `[(fixed_vector) = true]` option
-
-        4. **Small datasets (1-16 elements):** Use `std::vector` or `std::array` with simple structs instead of `std::map`/`std::set`/`std::unordered_map`.
-           ```cpp
-           // Bad - 2KB+ overhead for red-black tree/hash table
-           std::map<std::string, int> small_lookup;
-           std::unordered_map<int, std::string> tiny_map;
-
-           // Good - simple struct with linear search (std::vector is fine)
-           struct LookupEntry {
-             const char *key;
-             int value;
-           };
-           std::vector<LookupEntry> small_lookup = {
-             {"key1", 10},
-             {"key2", 20},
-             {"key3", 30},
-           };
-           // Or std::array if size is compile-time constant:
-           // std::array<LookupEntry, 3> small_lookup = {{ ... }};
-           ```
-           Linear search on small datasets (1-16 elements) is often faster than hashing/tree overhead, but this depends on lookup frequency and access patterns. For frequent lookups in hot code paths, the O(1) vs O(n) complexity difference may still matter even for small datasets. `std::vector` with simple structs is usually fine—it's the heavy containers (`map`, `set`, `unordered_map`) that should be avoided for small datasets unless profiling shows otherwise.
-
-        5. **Detection:** Look for these patterns in compiler output:
-           - Large code sections with STL symbols (vector, map, set)
-           - `alloc`, `realloc`, `dealloc` in symbol names
-           - `_M_realloc_insert`, `_M_default_append` (vector reallocation)
-           - Red-black tree code (`rb_tree`, `_Rb_tree`)
-           - Hash table infrastructure (`unordered_map`, `hash`)
-
-        **When to optimize:**
-        - Core components (API, network, logger)
-        - Widely-used components (mdns, wifi, ble)
-        - Components causing flash size complaints
-
-        **When not to optimize:**
-        - Single-use niche components
-        - Code where readability matters more than bytes
-        - Already using appropriate containers
-
-    *   **State Management:** Use `CORE.data` for component state that needs to persist during configuration generation. Avoid module-level mutable globals.
-
-        **Bad Pattern (Module-Level Globals):**
-        ```python
-        # Don't do this - state persists between compilation runs
-        _component_state = []
-        _use_feature = None
-
-        def enable_feature():
-            global _use_feature
-            _use_feature = True
-        ```
-
-        **Bad Pattern (Flat Keys):**
-        ```python
-        # Don't do this - keys should be namespaced under component domain
-        MY_FEATURE_KEY = "my_component_feature"
-        CORE.data[MY_FEATURE_KEY] = True
-        ```
-
-        **Good Pattern (dataclass):**
-        ```python
-        from dataclasses import dataclass, field
-        from esphome.core import CORE
-
-        DOMAIN = "my_component"
-
-        @dataclass
-        class MyComponentData:
-            feature_enabled: bool = False
-            item_count: int = 0
-            items: list[str] = field(default_factory=list)
-
-        def _get_data() -> MyComponentData:
-            if DOMAIN not in CORE.data:
-                CORE.data[DOMAIN] = MyComponentData()
-            return CORE.data[DOMAIN]
-
-        def request_feature() -> None:
-            _get_data().feature_enabled = True
-
-        def add_item(item: str) -> None:
-            _get_data().items.append(item)
-        ```
-
-        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

-## 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
