-name: automations
-description: Write ESPHome automation building blocks - triggers (on_* keys), actions and conditions. Use when adding or changing an on_* trigger, an action such as my_component.do_something, a condition, a callback registration method (add_on_*_callback), or code that calls build_callback_automation, build_automation, register_*_action or register_*_condition.
----
-
-# Automations: triggers, actions and conditions
-
-Automations have three building blocks: **Triggers** (fire when something happens), **Actions** (do
-something), and **Conditions** (check if something is true). The helpers named here are documented in
-their docstrings in `esphome/automation.py`.
-
-## Triggers: callback method (preferred)
-
-Use `build_callback_automation()` for simple triggers. This eliminates the need for a C++ Trigger class by
-using a lightweight pointer-sized forwarder struct registered directly as a callback. No `CONF_TRIGGER_ID`
-in the schema.
-
-**Python:**
-```python
-from esphome import automation
-
-CONFIG_SCHEMA = cv.Schema(
-    {
-        cv.GenerateID(): cv.declare_id(MyComponent),
-        cv.Optional(CONF_ON_STATE): automation.validate_automation({}),
-    }
-).extend(cv.COMPONENT_SCHEMA)
-
-
-async def to_code(config):
-    var = cg.new_Pvariable(config[CONF_ID])
-    await cg.register_component(var, config)
-    for conf in config.get(CONF_ON_STATE, []):
-        await automation.build_callback_automation(
-            var, "add_on_state_callback", [(bool, "x")], conf
-        )
-```
-
-`build_callback_automation` arguments: `parent`, `callback_method` (C++ method name), `args` (template args
-as `[(type, name)]` tuples), `config`, and optional `forwarder` (defaults to `TriggerForwarder<Ts...>`).
-
-For boolean filtering (e.g. `on_press`/`on_release`), use built-in forwarders with `args=[]`:
-```python
-for conf_key, forwarder in (
-    (CONF_ON_PRESS, automation.TriggerOnTrueForwarder),
-    (CONF_ON_RELEASE, automation.TriggerOnFalseForwarder),
-):
-    for conf in config.get(conf_key, []):
-        await automation.build_callback_automation(
-            var, "add_on_state_callback", [], conf, forwarder=forwarder
-        )
-```
-
-When the callback's parameters differ from the automation's arguments, or the trigger should only fire for
-some values, pass `params`, `forward` and `when`; the helper then generates a capture-less lambda (stored
-inline, nothing allocated). Name the parent with `automation.parent_ref(var)` and build `forward` from
-`MockObj` calls, not f-strings of C++:
-```python
-parent = automation.parent_ref(var)
-index = cg.RawExpression("index")
-await automation.build_callback_automation(
-    var,
-    "add_on_state_callback",
-    [(cg.StringRef, "x"), (cg.size_t, "i")],
-    conf,
-    params=[(cg.size_t, "index")],
-    forward=[cg.StringRef(parent.option_at(index)), index],
-)
-```
-`build_parent_callback_automation`, `build_trigger_callback`, `build_callback_automations` and
-`build_trigger_automations` cover the other shapes; see their docstrings in `esphome/automation.py`.
-
-When every action in a callback automation is inline (see Actions below), no `Automation` or action objects
-are generated: the callback calls one generated function, at the same RAM cost as a hand-written lambda. A
-custom forwarder blocks this unless its filter is also given as `params`, `forward` and `when`, so always pass
-them together:
-```python
-automation.CallbackAutomation(
-    CONF_ON_IDLE,
-    "add_on_state_callback",
-    forwarder=StateEnterForwarder.template(State.IDLE),
-    params=[(State, "state")],
-    forward=[],
-    when=f"state == {State.IDLE}",
-)
-```
-
-**C++: no trigger class needed.** The callback registration method must be templatized to accept both
-`std::function` and lightweight forwarder structs (which avoid heap allocation):
-```cpp
-class MyComponent : public Component {
- public:
-  // Must be a template -- accepts both std::function and pointer-sized forwarder structs
-  template<typename F> void add_on_state_callback(F &&callback) {
-    this->state_callback_.add(std::forward<F>(callback));
-  }
- protected:
-  // Use CallbackManager when callbacks are always registered (e.g. core components)
-  CallbackManager<void(bool)> state_callback_;
-  // Use LazyCallbackManager when callbacks are often not registered -- saves 8 bytes
-  // (nullptr vs empty std::vector) per instance when no callbacks are added
-  // LazyCallbackManager<void(bool)> state_callback_;
-};
-```
-
-Never type a registration method's parameter as `std::function`; that forces a heap allocation for every
-forwarder struct:
-```cpp
-// Bad
-void add_on_state_callback(std::function<void(bool)> &&callback) {
-  this->state_callback_.add(std::move(callback));
-}
-```
-
-| Type | Idle overhead (32-bit) | When to use |
-|------|----------------------|-------------|
-| `CallbackManager<void(Ts...)>` | 12 bytes (empty `std::vector`) | Callbacks are always or almost always registered |
-| `LazyCallbackManager<void(Ts...)>` | 4 bytes (`nullptr`) | Callbacks are often not registered (common case) |
-| `AutomationList<N, Ts...>` + `build_automation_lists` | 4 bytes per automation + count, none when unused | A hub fires its own `on_*` automations with no filter (4 B per automation vs 8 B per `Callback`) |
-| `automation.new_automation(args, conf)` + the parent's own fixed table | the table entry (pointer plus its own data) | Like `AutomationList`, but each automation needs a stored value of its own, e.g. a threshold the parent compares against |
-
-Both live in `esphome/core/helpers.h` and accept `std::function`, lambdas and forwarder structs through
-their templatized `add()` method. `LazyCallbackManager` is a drop-in replacement for `CallbackManager` that defers allocation until the first
-callback is added. Prefer it for entity-level callbacks where most instances have no subscribers.
-
-## Triggers: Trigger class method
-
-Use `build_automation()` with a `Trigger<Ts...>` subclass only when the forwarder needs **mutable state
-beyond a single `Automation*` pointer** (e.g. edge detection tracking previous state, timing logic).
-
-**Python:**
-```python
-TurnOnTrigger = my_ns.class_("TurnOnTrigger", automation.Trigger.template())
-
-CONFIG_SCHEMA = cv.Schema(
-    {
-        cv.Optional(CONF_ON_TURN_ON): automation.validate_automation(
-            {cv.GenerateID(CONF_TRIGGER_ID): cv.declare_id(TurnOnTrigger)}
-        ),
-    }
-)
-
-
-async def to_code(config):
-    for conf in config.get(CONF_ON_TURN_ON, []):
-        trigger = cg.new_Pvariable(conf[CONF_TRIGGER_ID], var)
-        await automation.build_automation(trigger, [], conf)
-```
-
-**C++:**
-```cpp
-class TurnOnTrigger : public Trigger<> {
- public:
-  explicit TurnOnTrigger(MyComponent *parent) : last_on_{false} {
-    parent->add_on_state_callback([this](bool state) {
-      if (state && !this->last_on_)
-        this->trigger();
-      this->last_on_ = state;
-    });
-  }
- protected:
-  bool last_on_;
-};
-```
-
-## Actions
-
-```cpp
-template<typename... Ts> class MyAction : public Action<Ts...> {
- public:
-  explicit MyAction(MyComponent *parent) : parent_(parent) {}
-  void play(const Ts &...) override { this->parent_->do_something(); }
- protected:
-  MyComponent *parent_;
-};
-```
-Register it without writing a builder:
-```python
-automation.register_simple_action(
-    "my_component.do_something", MyAction, schema, synchronous=True
-)
-```
-The constructor receives the object named by `config[CONF_ID]`. Use `register_bare_action` for a
-no-argument constructor, `register_parented_action` for a class deriving from `Parented<T>`, and the
-`@automation.register_action(...)` decorator only when the builder must also set fields.
-
-Use `synchronous=True` for actions that run to completion inside `play()` without deferring. Use
-`synchronous=False` if the action may suspend/defer execution (e.g. `delay`, `wait_until`, `script.wait`)
-or store trigger arguments for later use.
-
-**Actions that only forward templatable values to their parent need no C++ class.** Register them with
-`register_apply_action`; do not write a `TEMPLATABLE_VALUE` class or a builder for this shape.
-```python
-automation.register_apply_action(
-    "my_component.set_gains",
-    schema,
-    automation.ApplyField(CONF_KP, "set_kp", cg.float_),
-    automation.ApplyField(CONF_KI, "set_ki", cg.float_),
-)
-```
-The `ApplyField`, `ApplyCall` and `register_apply_action` docstrings in `esphome/automation.py` cover the
-rest; `cover.control` and `cover.template.publish` are in-tree examples. An action whose input is a byte
-payload passes `automation.ApplyBytes(CONF_DATA, "send({})")` in the same call; a constant payload stays in
-flash and a lambda's vector is forwarded as data and size. `TEMPLATABLE_VALUE` with `cg.templatable` stays
-for actions whose `play()` has real logic beyond forwarding values.
-
-Adjacent `register_apply_action` and `lambda:` actions in a list merge into one generated function and one
-object, which saves 12 to 16 bytes of RAM per merged action. An action with its own C++ class ends the merged
-run, so prefer `register_apply_action` wherever the action allows it. Because of this, `build_action_list` can
-return fewer objects than the config has entries. A builder that wraps `apply_action_builder` may do other work
-first, but must return its result unchanged and not use it. A builder that must generate its own statements, and
-is registered with `automation.ApplyAction`, can call `apply_statements_action` and still merge; `script.execute`
-is an example. `if`, `choose`, `while` and `repeat` whose bodies are all inline become C++ control flow in the
-same function, and `register_apply_condition` and `lambda:` conditions become plain expressions there.
-
-## Conditions
-
-```cpp
-template<typename... Ts> class MyCondition : public Condition<Ts...> {
- public:
-  explicit MyCondition(MyComponent *parent) : parent_(parent) {}
-  bool check(const Ts &...) override { return this->parent_->is_active(); }
- protected:
-  MyComponent *parent_;
-};
-```
-Register with `automation.register_simple_condition("my_component.is_active", MyCondition, schema)`;
-`register_bare_condition`, `register_parented_condition` and the decorator follow the action rules.
-
-**Conditions that only test their parent need no C++ class either.** Register them with
-`register_apply_condition`; the expression is applied to the parent, and an `ApplyCall` compares against
-config values.
-```python
-automation.register_apply_condition("my_component.is_active", schema, "is_active()")
-automation.register_apply_condition(
-    "my_component.state_is",
-    schema,
-    automation.ApplyCall("state == {}", ((CONF_STATE, cg.bool_),)),
-)
-```
-`cover.is_open`, `rtttl.is_playing` and `component.is_idle` are in-tree examples.

-name: breaking-changes
-description: Decide whether an ESPHome change breaks public API and handle it - what counts as public C++ and Python API, the deprecation window, ESPDEPRECATED for C++, cv.rename_key and deprecation warnings for config keys, and the migration notes a PR needs. Use when removing, renaming or changing the signature of a config option, a public C++ member or a core Python helper.
----
-
-# Public API and breaking changes
-
-Full policy: https://developers.esphome.io/contributing/code/#public-api-and-breaking-changes
-
-## What is public
-
-- **C++ in components:** only features documented at [esphome.io](https://esphome.io) are public API.
-  Undocumented `public` members are internal.
-- **C++ core and 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).
-- **Python:** all documented configuration options are public API. Python code in `esphome/core/` that
-  existing core components use is stable API. Other Python code is internal unless explicitly documented
-  for external component use.
-- Changing the signature of a lambda that code generation injects is not a breaking change.
-
-## Policy
-
-- Aim for a **6-month deprecation window** when possible.
-- Clean breaks are allowed for signature changes, deep refactorings and resource constraints.
-- The migration path goes in the PR description (it generates the release notes).
-- A blog post is required for core/base class changes or significant architectural changes.
-
-Checklist:
-- [ ] Clear justification (RAM/flash savings, architectural improvement)
-- [ ] Explored non-breaking alternatives
-- [ ] Added deprecation warnings if possible (`ESPDEPRECATED` for C++)
-- [ ] Documented migration path in the PR description with before/after examples
-- [ ] Updated all internal usage and esphome.io
-- [ ] Tested backward compatibility during the deprecation period
-
-## Deprecating 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(); }
-```
-
-## Deprecating config keys
-
-For a renamed key, use the shared `cv.rename_key` validator with `removed_in` (and `component` for
-context); it warns and migrates automatically:
-```python
-CONFIG_SCHEMA = cv.All(
-    cv.rename_key(
-        CONF_OLD_KEY, CONF_NEW_KEY, removed_in="2026.6.0", component="my_component"
-    ),
-    cv.Schema({...}),
-)
-```
-For other deprecations, warn manually during validation:
-```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
-```
-Cover the old syntax with a `validate.*.yaml` test (see the `component-tests` skill), and keep the language
-schema correct (see the `config-validation` skill).

----

-# Reviewing ESPHome pull requests
-
-ESPHome parses YAML into C++ firmware for memory-constrained microcontrollers
-(ESP32, ESP8266, RP2040, LibreTiny). Review changes with that in mind: RAM and
-flash are scarce, and code runs unattended for months.
-
-`AGENTS.md` in the repository root is the contributor guide, and the skills it
-lists (`component-codegen`, `config-validation`, `automations`,
-`embedded-memory`, `component-tests`, `breaking-changes`) hold the detail. They
-are the authority when they disagree with this summary. The developer
-documentation at https://developers.esphome.io explains the component lifecycle
-and the reasoning behind these rules. This skill lists the concrete things worth
-flagging in a review; read the matching skill for the detail behind any item.
-
-Only raise findings that the diff actually introduces or changes. Do not ask for
-drive-by cleanup of pre-existing code the PR did not touch.
-
-## Scope: shared code does not ride a component PR
-
-Check the file list first. A PR titled for one component (`[ld2450] ...`) must
-not also change code other components build on: `esphome/core/`, the entity
-platform components (`esphome/components/sensor/`, `esphome/components/text_sensor/`
-including its `filter.*`, `binary_sensor/`, `number/`, ...), the buses
-(`esphome/components/{i2c,spi,uart}/`), `network/`, `socket/`, the shared
-constants (`esphome/components/const/`, `esphome/const.py`),
-`esphome/automation.py`, `esphome/cpp_generator.py` or `esphome/config_validation.py`.
-Flag it and ask for the shared change to move into its own PR, which lands first
-and is reviewed by that code's owners; the component PR then builds on it. This
-holds even when the shared change is small or only the component uses it today.
-The exception is a shared change that must update several components in the same
-PR so none of them breaks in between (a `[core]` or `[components]` PR that adds a
-helper and moves its callers at once).
-
-Not shared code: the component's own platform files (`esphome/components/<c>/sensor.py`,
-`text_sensor/__init__.py`, ...), its new `USE_*` lines in `esphome/core/defines.h`,
-and its `CODEOWNERS` entry.
-
-## Memory and embedded constraints (highest value)
-
-Heap allocation after `setup()` is treated as a reliability bug, not a
-performance nit, because it fragments a small shared heap. Flag:
-
-- New heap allocation on a hot path or after setup that could be avoided.
-- `std::vector` where the size is known at compile time (use `std::array`, or
-  `StaticVector<T, N>` when a `push_back` API is needed) or fixed at runtime
-  init (use `FixedVector<T>`).
-- Listener / child-entity registration lists stored as `std::vector`; these have
-  a compile-time-known count and should use `cg.slot_list()` plus
-  `SLOT_LIST` (or `cg.slot_counter()` plus `StaticVector`).
-- `std::vector<uint8_t>` for a byte buffer that never grows: prefer
-  `std::unique_ptr<uint8_t[]>` or `std::array`.
-- `std::map` / `std::set` / `std::unordered_map` for small datasets (1-16
-  elements): a `std::vector` of a small struct with linear search is lighter.
-- `std::deque` anywhere: it allocates 512-byte blocks and should be avoided.
-- `std::string` storing a value set once from config: prefer `StringRef` (the
-  literal already lives in flash).
-- `std::string` / `std::to_string` / string-returning helpers on hot paths where
-  a buffer or view API exists.
-- A `set_timeout` / `set_interval` / `defer` lambda whose captures exceed 8 bytes
-  on 32-bit or are not trivially copyable (`this` plus two 4-byte values, `this`
-  plus a member function pointer, a `std::string`, a `std::function`):
-  `std::function` then heap-allocates each time it is scheduled. Flag it on
-  retries, re-armed timeouts and hot-path `defer`; a `set_interval` set up once
-  in `setup()` is a single allocation. `[this]` plus one 4-byte value fits.
-
-## C++ conventions
-
-- Include what you use: a file referencing a symbol must include the header that
-  declares it, even if it currently arrives transitively. New or changed uses of
-  a symbol need the matching include.
-- Prefix all member access with `this->`.
-- Naming: `lower_snake_case` for functions/methods/variables, `UpperCamelCase`
-  for classes/structs/enums, `UPPER_SNAKE_CASE` for namespace-scope constants,
-  trailing underscore on protected/private fields.
-- `enum class` values must be prefixed with the enum name in `UPPER_SNAKE_CASE`
-  (e.g. `UARTFlushResult::UART_FLUSH_RESULT_SUCCESS`). Bare names like `SUCCESS`,
-  `FAIL`, or `OK` collide with SDK macros on some platforms and break the build.
-- Prefer `const`/`enum` over `#define`; `#define` is only for conditional
-  compilation and code-generation sizes.
-- Never call `millis()` in a `loop()` body; use
-  `App.get_loop_component_start_time()`. A rate-limit gate below ~16 ms (the loop
-  period) does nothing.
-- Pick the timing primitive by cadence: gated `loop()` under 250 ms,
-  `set_interval` at 500 ms and above.
-- Do not override a base method to return the value it already returns (e.g.
-  `get_setup_priority()` returning `setup_priority::DATA`).
-- Wrap string literals passed as printf `%s` args in `LOG_STR_LITERAL()`.
-- Required, invariant dependencies should be constructor parameters, not setters.
-- Callback registration methods must be templated (`template<typename F>`), not
-  typed as `std::function`, so lightweight forwarders avoid a heap allocation.
-- Two-space indent, `using` over `typedef`, wrap at 120 columns.

-New components often hand-write code a helper already covers. Ask for the
-helper; `AGENTS.md` section 4 and the `component-codegen` skill have the detail.
-

-| --- | --- |

-| set warning / `return` / clear warning around a bus result | `if (!this->status_comm_result(ok)) return;` |
-| hand-written `set_x_sensor()` plus `x_sensor_` member | `SUB_SENSOR(x)`, `SUB_BINARY_SENSOR`, `SUB_TEXT_SENSOR`, `SUB_SWITCH`, ... |
-| `if CONF_X in config: s = await sensor.new_sensor(config[CONF_X])` plus setter | `sensors = sensor.sub_sensors(config)` then `await sensors(CONF_X, hub.set_x_sensor)` |
-| hand-written `{"a": MyEnum.MY_ENUM_A, ...}` dict | `MyEnum.options("a", "b", prefix="MY_ENUM_")` |
-| loops on `available()` / `read_byte()` | UART `read_available(on_byte)`, `discard_available()`, `LineReader<N>`, `FrameReader<N, HEADER...>` |
-| hand-rolled CRC, checksum or bit loop | `crc8`, `crc16`, `xor_bytes`, `sum16_bytes`, `encode_uint16`, ... (`esphome/core/helpers.h`) |
-| integer split into buffer bytes by hand (`buf[0] = v >> 8; buf[1] = v;`) | `put_be16`/`24`/`32`, `put_le16`, `put_le32` (`esphome/core/helpers.h`) |
-| bare `mark_failed()`, or `ESP_LOGE` then `mark_failed()` | `this->mark_failed(LOG_STR("reason"))` or `LOG_STR(ESP_LOG_MSG_COMM_FAIL)` |
-| button/switch/number/select C++ class that only calls the hub | `ApplyButton`, `ApplySwitch`, `ApplyNumber`, `ApplySelect` with `apply=` |
-| action or condition class that only forwards to the parent | `register_apply_action` / `register_apply_condition` |
-| enum-to-string `switch` returning literals | `PROGMEM_STRING_TABLE` with `get_log_str` / `get_progmem_str` |
-| `if (x := config.get(CONF_X)) is not None: cg.add(var.set_x(x))` | `cg.add_optional(var.set_x, config.get(CONF_X))`, when the setter takes the value unchanged |
-
-## Python conventions
-
-- Type-annotate every new function signature (params and return), new dataclass
-  fields, and new module-level variables. Import `ConfigType` from
-  `esphome.types`.
-- Use the walrus operator to avoid a double lookup, e.g.
-  `if (blah := config.get(CONF_BLAH)) is not None:`.
-- Reuse existing validators from `config_validation.py` (`cv.rename_key`,
-  `cv.has_exactly_one_key`, etc.) via `cv.All(...)` instead of hand-rolling.
-- A new or changed validator function that wraps, chooses or builds a schema
-  must be decorated with `@schema_extractor(...)` and handle `SCHEMA_EXTRACT`,
-  or `script/build_language_schema.py` silently drops the keys behind it (see
-  the `config-validation` skill).
-- `esphome/const.py` is frozen: no new `CONF_` constants there. Define them in
-  the component's own `.py`, or in `esphome/components/const/__init__.py` when
-  shared. The same constant defined in three or more component files fails CI.
-- State that must persist during code generation goes in `CORE.data` namespaced
-  under the component `DOMAIN` (a `@dataclass`), not module-level mutable globals.
-- Prefer callback-based triggers via `build_callback_automation()`; only use a
-  `Trigger<Ts...>` subclass when the forwarder needs mutable state.
-
-## Testing and coverage
-
-- New and changed lines and branches need test coverage, including defensive
-  early-returns, error paths, and no-op guards. A mocked-out function is not
-  covered; exercise the real call path too.
-- Component YAML tests live in `tests/components/<component>/`. Never define
-  buses (uart, i2c, spi, modbus) directly in a test file: pull them from
-  `tests/test_build_components/common/` through dict-style `packages:` so CI can
-  group builds. List-style packages or top-level merge keys block grouping.
-- Config-only checks use the `validate.*.yaml` prefix; compiled checks use
-  `test.*.yaml`.
-
-## Naming user-facing functions
-
-Documented lambda methods, actions and config keys are public API, so a bad name
-is hard to fix once released. Flag:
-
-- A boolean where `true` means off (`display_off(true)`): name the positive
-  state, e.g. `set_power(bool on)`.
-- A name that differs from a sibling component's name for the same operation.
-
-Before a release, rename outright; after, follow the breaking-change policy
-below.
-
-## Breaking changes and public API
-
-- Base classes under `esphome/core/` and documented config options are public
-  API. Undocumented `public` members of a component are internal.
-- A breaking change needs justification, a migration path in the PR description,
-  and a deprecation window where feasible (`ESPDEPRECATED` in C++,
-  `cv.rename_key(..., removed_in=...)` in Python). Changing a codegen-injected
-  lambda signature is not a breaking change.
-
-## Process and PR hygiene
-
-- PR titles start with a `[tag]` prefix: the component name (e.g. `[uart] ...`)
-  or `[core]` for shared code.
-- Prose in docs, comments, and commit messages should be plain English. Keep
-  inline comments short and only where the code is not self-explanatory; do not
-  restate what the code says.
-- Verify the PR fills out `.github/PULL_REQUEST_TEMPLATE.md` and adds
-  `CODEOWNERS` entries for a new component.

-
-## Metadata
-
-- `DOMAIN`: required in every component's `__init__.py`, set to the component's own name as a plain string
-  (e.g. `DOMAIN = "my_component"`). Other code refers to the component through it, e.g.
-  `from esphome.components.my_component import DOMAIN`. Keep it in alphabetical order with the other
-  metadata constants. CI (`lint_component_domain`) fails without it.
-- `DEPENDENCIES`: list of required components.
-- `AUTO_LOAD`: components to automatically load. Not a way to put entities under the component's own key;
-  see "Entities of a hub" below.
-- `CONFLICTS_WITH`: incompatible components.
-- `CODEOWNERS`: GitHub usernames responsible for maintenance.
-- `MULTI_CONF`: whether multiple instances are allowed.
-
-## Basic pattern
-
-```python
-import esphome.codegen as cg
-import esphome.config_validation as cv
-from esphome.const import CONF_KEY, CONF_ID
-
-DOMAIN = "my_component"
-CONF_PARAM = "param"  # A constant that does not yet exist in esphome/const.py
-
-my_component_ns = cg.esphome_ns.namespace("my_component")
-MyComponent = my_component_ns.class_("MyComponent", cg.Component)
-
-CONFIG_SCHEMA = cv.Schema(
-    {
-        cv.GenerateID(): cv.declare_id(MyComponent),
-        cv.Required(CONF_KEY): cv.string,
-        cv.Optional(CONF_PARAM, default=42): cv.int_,
-    }
-).extend(cv.COMPONENT_SCHEMA)
-
-
-async def to_code(config):
-    var = cg.new_Pvariable(config[CONF_ID])
-    await cg.register_component(var, config)
-    cg.add(var.set_key(config[CONF_KEY]))
-    cg.add(var.set_param(config[CONF_PARAM]))
-```
-
-```cpp
-namespace esphome::my_component {
-
-class MyComponent : public Component {
- public:
-  void setup() override;
-  void loop() override;
-  void dump_config() override;
-
-  void set_key(const char *key) { this->key_ = StringRef(key); }
-  void set_param(int param) { this->param_ = param; }
-
- protected:
-  StringRef key_;
-  int param_{0};
-};
-
-}  // namespace esphome::my_component
-```
-
-When the setter takes the value unchanged, use `cg.add_optional(var.set_blah, config.get(CONF_BLAH))`; it
-is not awaited, and it skips only `None`, so `0` and `False` are still set. Required, invariant
-dependencies are constructor arguments to `cg.new_Pvariable()`, not setters.
-
-## Entity platforms
-
-**Sensor:**
-```python
-from esphome.components import sensor
-
-CONFIG_SCHEMA = sensor.sensor_schema(MySensor).extend(
-    cv.polling_component_schema("60s")
-)
-
-
-async def to_code(config):
-    var = await sensor.new_sensor(config)
-    await cg.register_component(var, config)
-```
-
-**Binary sensor:**
-```python
-from esphome.components import binary_sensor
-
-CONFIG_SCHEMA = binary_sensor.binary_sensor_schema().extend({...})
-
-
-async def to_code(config):
-    var = await binary_sensor.new_binary_sensor(config)
-```
-
-**Switch:**
-```python
-from esphome.components import switch
-
-CONFIG_SCHEMA = switch.switch_schema().extend({...})
-
-
-async def to_code(config):
-    var = await switch.new_switch(config)
-```
-
-## Entities of a hub
-
-A new component's entities go in platform files (`sensor.py`, `binary_sensor.py`, ...) that take the hub's
-id, never under the hub's own key with their platforms added to `AUTO_LOAD` to make that work. Auto loading
-a platform because the C++ uses its type is fine. See
-https://developers.esphome.io/architecture/components/#exposing-multiple-entities.
-```yaml
-# Bad - entities under the hub's key
-my_hub:
-  connected:
-    name: Connected
-
-# Good - the hub, then one platform entry that holds its entities
-my_hub:
-  id: hub1
-binary_sensor:
-  - platform: my_hub
-    my_hub_id: hub1  # optional with a single hub
-    connected:
-      name: Connected
-```
-
-**Optional child entities of a hub:** bind the config once with `sensor.sub_sensors(config)` (or
-`sub_binary_sensors`, `sub_text_sensors`, `sub_buttons`, `sub_switches`, `sub_numbers`, `sub_selects` in
-their domains), adding `parent=hub` for entities that derive from `Parented<T>`, then make one call per
-key, even when there is only one. A call creates the entity only when its key is configured, passes it to
-the setter and returns it (or `None`); extra arguments such as `min_value` or `options` go on the call.
-Always name the setter explicitly on the object that owns it, never with `getattr` and an f-string, and
-keep that variable short (`var` for the component itself, `hub` for one fetched with `cg.get_variable`) so
-the calls fit on one line. Loops whose setter also takes an index, such as `set_gate_threshold(x, n)`, stay
-as they are.
-```python
-# my_hub/sensor.py
-async def to_code(config):
-    hub = await cg.get_variable(config[CONF_MY_HUB_ID])
-    sensors = sensor.sub_sensors(config)
-    await sensors(CONF_TEMPERATURE, hub.set_temperature_sensor)
-    await sensors(CONF_HUMIDITY, hub.set_humidity_sensor)
-
-
-# my_hub/button.py
-async def to_code(config):
-    hub = await cg.get_variable(config[CONF_MY_HUB_ID])
-    buttons = button.sub_buttons(config, parent=hub)
-    await buttons(CONF_RESTART, hub.set_restart_button)
-```
-
-**Hub forwarding entities need no C++ class:** a button, switch, number or select that only calls its hub
-uses `button.ApplyButton` (`switch.ApplySwitch`, `number.ApplyNumber`, `select.ApplySelect`) in its schema
-and `apply=` on the `sub_*` call. The body is a call on the hub with `entity` and `state`, `value` or
-`index`/`option` in scope; on a switch, number or select `publish="before"` or `"after"` publishes the
-state, and `publish="on_success"` publishes only when the hub call returns true (a write the device can
-refuse). `publish="momentary"` is only for legacy action switches (restart, factory reset): it publishes off
-and runs the body only when turned on. Never use it for a new entity; an action is a button.
-```python
-switches = switch.sub_switches(config, parent=hub)
-await switches(CONF_BLUETOOTH, None, apply="set_bluetooth(state)", publish="after")
-```
-Restore an owned or standalone switch in `setup()` with `sw->restore()`, or `restore(default)` to still
-drive a state when the restore mode is disabled. A hub that applies its switches' restored states itself
-reads `sw->get_initial_write_state()`, which already applies `inverted`.
-
-**A hub that forwards data to its children:** when what each child does with the data is known at build time
-(decode a register field, match a key or tag, publish a value), declare a `cg.HubFunction` once in the hub's
-`__init__.py` and have each platform add one item per entity, built from codegen expressions. Code generation writes
-one function per hub. Pass `define=` and put the hub's `HUB_PUBLISHER(<name>, args...)` (in a public section; it
-ends on `public:`) and its call under that `#ifdef`; call the pointer only when it is not null. The children stay
-plain entities, with no listener class or list. A child that lost a `Component` base keeps its dump lines through
-a second hub function (`"dump"`, a `const char *` tag parameter, no define of its own) that the hub's
-`dump_config()` calls inside the value function's `#ifdef`; every child adds to both.
-
-**Entities that each watch a register field:** when every field (register, shift, mask, match) is known at
-build time, use the rule above (see `bq25186`). A binary sensor tests its field value against an on-values
-bitmap (`match`); a one-bit field reads the bit (simplified from bq25186's `_state_expression`):
-```python
-# hub __init__.py
-STATUS_PUBLISHER = cg.HubFunction(
-    "status",  # esphome__<hub>__status_fn, passed to HUB_PUBLISHER(status, ...)'s setter
-    cg.void,
-    [(BQ25186StatusRegisters.const_ref(), "status")],
-    define="USE_BQ25186_STATUS_PUBLISHER",
-)
-STATUS = STATUS_PUBLISHER.param("status")
-
-# platform to_code, per configured entity
-value = (STATUS[reg] >> shift) & mask
-if mask != 0x01 or match != 0b10:  # 0b10: a one-bit field that is on when set
-    value = (cg.MockObj(f"{match:#06b}") >> value) & 1
-STATUS_PUBLISHER.add(hub, parent_ref(var).publish_state(value))
-```
-Store a field description per entity (a struct in a `SlotList` sized by `cg.slot_list`) only when the
-field is chosen at run time, as in `sen6x`, where the status bit depends on the variant read in `setup()`.
-Never a template per bit or a virtual listener base (a second vptr per entity).
-
-## Other helpers
-
-- **Pins and referenced components:** set them with `await cg.add_pin(var.set_cs_pin, config[CONF_CS_PIN])`
-  and `await cg.add_variable(var.set_bus, config[CONF_BUS_ID])`; both skip a `None` value, so pass
-  `config.get(KEY)` for an optional key, and return what they created. Use `cg.register_parented` for
-  `set_parent`.
-- `uart.new_uart_component(config, *ctor_args)` (and `i2c.new_i2c_component`, `spi.new_spi_component`,
-  `modbus.new_modbus_client_component`, `ble_client.new_ble_node_component`) constructs, registers and
-  attaches in one call.
-- A fixed buffer sized from the config is a file-scope static (BSS, not heap):
-  `buf = cg.static_buffer(config[CONF_ID], cg.uint8, size)`, named after its owner so `esphome analyze-memory`
-  counts it there; pass `buf` to the constructor.
-  A buffer that may live in PSRAM takes `psram=True`: PSRAM builds get a zeroed `psram_buffer<T>(size)` allocation
-  instead, so pass `buf` once and mark the component failed in `setup()` if it is nullptr. `align=4` emits
-  `alignas(4)`, so a word-aligned byte buffer stays `uint8`. `size` may be an expression such as `MyClass.static_("buffer_size")(n)`, which renders
-  `ns::MyClass::buffer_size(n)`.
-- `display.add_writer(var, config)` sets the lambda.
-- `MyEnum.options("on", prefix="MY_ENUM_")` builds an enum dict.
-- `button.restart_button_schema(cls)` (and `factory_reset_`, `query_`) are button presets.
-- `fv.get_declaring_config(id)` finds a hub's config in final validation.
-
-## State during code generation
-
-Use `CORE.data` for component state that needs to persist during configuration generation, namespaced
-under the component's `DOMAIN` and held in a `@dataclass`. Avoid module-level mutable globals: they
-persist between compilation runs if the host process (e.g. device-builder) doesn't fork/exec, whereas
-`CORE.data` is cleared between runs.
-
-```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
-```
-
-Don't use flat keys such as `CORE.data["my_component_feature"] = True`. Some components use `TypedDict`
-instead of a dataclass; both are acceptable.

-Run them with `script/test_build_components`. Use `-c <component>` to test specific components and
-`-t <target>` for specific platforms.
-
-- **Keep build-test variants few:** one `test.<platform>.yaml` per platform the code actually differs on.
-  A variant per board for platform-identical code only adds CI time.
-- **Config-only test files (`validate.*.yaml`):** use this prefix when a YAML file only needs to exercise
-  schema/validation paths and does not need to be compiled. CI runs `validate.*.yaml` files with
-  `esphome config` only and skips them during compile. The grammar mirrors `test.*.yaml`:
-  - `validate.<platform>.yaml`: base config-only test
-  - `validate-<variant>.<platform>.yaml`: config-only variant
-
-  Use this for deprecated-syntax migration tests, schema edge cases, or platform-specific validation
-  branches where building firmware adds no signal. A component may have any mix of `test.*.yaml` and
-  `validate.*.yaml` files. Validate files never participate in bus grouping; each one runs as its own
-  `esphome config` invocation.
-
-  When a PR's only edits to a component are `validate.*.yaml` files (no source changes, no `test.*.yaml`
-  changes, and the component isn't pulled in as a dependency of another changed component), CI skips the
-  compile stage for that component and only runs config validation. This is decided in
-  `script/determine-jobs.py` via `_component_change_is_validate_only` and surfaced as the
-  `validate_only_components` output that the `test-build-components-split` job consumes.
-
-## Grouping with packages
-
-Components that use shared bus packages can be grouped together in CI to reduce build count. **Never define
-buses (uart, i2c, spi, modbus) directly in test YAML files**; always use packages from
-`test_build_components/common/`.
-
-All includes in test files must go through dict-style `packages:` so that batch grouping works; the
-grouping scripts only understand dict-style packages. Never use list-style packages
-(`packages: [- !include ...]`) or top-level merge keys (`<<: !include common.yaml`). Bus packages are keyed
-by the bus name; the component's `common.yaml` is keyed by the component name (e.g.
-`cst328: !include common.yaml`):
-```yaml
-# test.esp32-idf.yaml - everything included via named packages
-packages:
-  uart: !include ../../test_build_components/common/uart_115200/esp32-idf.yaml
-  my_component: !include common.yaml
-```
-```yaml
-# common.yaml - component config only, NO bus definitions
-my_component:
-  id: my_instance
-
-sensor:
-  - platform: my_component
-    name: My Sensor
-```
-Components that define buses directly are flagged as "NEEDS MIGRATION" and cannot be grouped, increasing
-CI build time. `!extend` and `!remove` in a `test.*.yaml` also make the component ungroupable; add a
-standalone entity with its own id instead.
-
-A test that needs a shared component in a particular state (`esp32_ble` security settings, an option that
-PSRAM rejects) cannot be grouped: the merged block wins and the whole batch fails. Add the component to
-`ISOLATED_COMPONENTS` in `script/analyze_component_buses.py`, or move the option to a `test-<variant>` file.
-
-To verify that all components can be tested together without ID conflicts or configuration issues:
-```bash
-./script/test_component_grouping.py -e config --all
-```
-This tests all components in a single build to catch conflicts that might not appear when testing
-components individually. Use `-e config` for fast configuration validation, or `-e compile` for full
-compilation testing.

-# Configuration validation
-
-ESPHome validates YAML with `voluptuous` schemas built from `esphome/config_validation.py` (`cv`). The
-same schemas are also walked by `script/build_language_schema.py`, which produces the JSON language schema
-that editors and the dashboard use for completion and checking. A validation change is only finished when
-both still work.
-
-## Writing schemas
-
-- **Type hints:** validators are typed like any other function: `def validate_x(config: ConfigType) ->
-  ConfigType:`, with `ConfigType` imported from `esphome.types`.
-- **One schema per model:** when a component's options depend on a `model` key, use
-  `cv.typed_schema({...}, key=CONF_MODEL, default_type=...)` with each model's own keys and defaults, not
-  one schema plus a validator that rejects keys and fills defaults afterwards.
-- **Reuse existing validators:** before writing a custom validator, check for an existing one in
-  `config_validation.py` and compose it in `cv.All(...)` rather than duplicating logic across components.
-  For example, rename a config key with `cv.rename_key(CONF_OLD, CONF_NEW, removed_in="2026.6.0")`, and
-  reject mutually-exclusive keys with `cv.has_at_most_one_key(...)` / `cv.has_exactly_one_key(...)`. See
-  how `api` composes `cv.has_exactly_one_key` + `cv.rename_key`.
-- **Common validators:** `cv.int_`, `cv.float_`, `cv.string`, `cv.boolean`, `cv.int_range(min=0,
-  max=100)`, `cv.positive_int`, `cv.percentage`.
-- **Complex validation:** `cv.All(cv.string, cv.Length(min=1, max=50))`, `cv.Any(cv.int_, cv.string)`.
-- **Platform-specific:** `cv.only_on(["esp32", "esp8266"])`, `esp32.only_on_variant(...)`,
-  `cv.only_on_esp32`, `cv.only_on_esp8266`, `cv.only_on_rp2040`.
-- **Framework-specific:** `cv.only_with_framework(...)`, `cv.only_with_arduino`. On the ESP32, Arduino is
-  built as a component of ESP-IDF, so an ESP-IDF API, sdkconfig option or version floor is there on both
-  frameworks: gate on `esp32.require_idf_version(cv.Version(5, 5, 3), "psram_dma")`, which checks the
-  platform and the ESP-IDF under either framework, as `spi`, `usb_host` and `wifi` do. Reserve
-  `cv.only_with_framework("esp-idf")` for a build that has been tried on Arduino and fails there, and write
-  the actual failure next to it (`sendspin`: arduino-esp32 below ESP-IDF 6.0 bundles a second libsodium,
-  and from 6.0 sendspin-cpp's enumerators collide with `Arduino.h` macros such as `DISPLAY`).
-- **Schema extensions:**
-  ```python
-  CONFIG_SCHEMA = cv.Schema({ ... })
-   .extend(cv.COMPONENT_SCHEMA)
-   .extend(uart.UART_DEVICE_SCHEMA)
-   .extend(i2c.i2c_device_schema(0x48))
-   .extend(spi.spi_device_schema(cs_pin_required=True))
-  ```
-- **Constants:** `esphome/const.py` is frozen; do not add new `CONF_` constants there. Define a
-  component-local constant in the component's own `.py`; for a constant shared by multiple components, add
-  it to `esphome/components/const/__init__.py`. CI (`lint_constants_usage`) fails if the same constant is
-  defined in three or more component files. Constants used in core files (those not under
-  `esphome/components`) may be added to `esphome/const.py` but will require adjustment to the CI check.
-- **Renamed or removed keys:** see the `breaking-changes` skill for `cv.rename_key` and manual
-  deprecation warnings.
-- **Config-only tests:** schema edge cases and deprecated-syntax migrations go in `validate.*.yaml` test
-  files (see the `component-tests` skill).
-
-## Schema extraction
-
-`script/build_language_schema.py` sets `esphome.schema_extractors.EnableSchemaExtraction = True` before it
-imports any component, then walks every `CONFIG_SCHEMA` (and platform schema) recursively. It understands
-`cv.Schema`, `cv.All`, `cv.Any`, dicts of `cv.Required` / `cv.Optional` keys, `.extend()`, `cv.ensure_list`,
-`cv.typed_schema`, registries and the known `cv` validators. **A plain function it cannot see into**: a
-custom validator that builds or picks a schema at validation time hides every key behind it, and the
-dumper silently emits nothing for them. CI only runs the script with `--check`, which does not compare the
-output, so a lost schema is not caught.
-
-When a validator function wraps, chooses or builds a schema (rather than checking a single value), make it
-visible to the dumper:
-
-1. Decorate it with `@schema_extractor("<type>")` from `esphome.schema_extractors`.
-2. At the top of the function, return the data for that type when it is called with `SCHEMA_EXTRACT`
-   instead of a config value. Compare with `is` (`value is SCHEMA_EXTRACT`); older code uses `==`.
-
-```python
-from esphome.schema_extractors import SCHEMA_EXTRACT, schema_extractor
-
-
-@schema_extractor("schema")
-def _outgoing_connection_schema(config: ConfigType | None) -> ConfigType:
-    if config is SCHEMA_EXTRACT:
-        return _OUTGOING_CONNECTION_SCHEMA
-    if config is None:
-        config = {}
-    return _OUTGOING_CONNECTION_SCHEMA(config)
-```
-
-The type names the dumper accepts, and what `SCHEMA_EXTRACT` must return for each, are in the
-`hidden_schemas` branch of `convert()` in `script/build_language_schema.py`. The common ones:
-
-| Type | Return for `SCHEMA_EXTRACT` | Example |
-|------|-----------------------------|---------|
-| `"schema"` | the schema (or a representative one) to walk | `api` `_outgoing_connection_schema`, `restore_state_schema` in `esphome/core/entity_helpers.py`, `model_schema_extractor` in `esphome/components/mipi/__init__.py` |
-| `"enum"` | the dict of options | `sensor_entity_category` in `esphome/components/sensor/__init__.py` |
-| `"one_of"` | the list of options | `cv.one_of` |
-| `"maybe"` | `(validator, key)` for a scalar shorthand | `cv.maybe_simple_value`, `maybe_conf` in `esphome/automation.py` |
-| `"templatable"` | the inner validator | `cv.templatable` |
-| `"automation"` | the automation schema | `automation.validate_automation` |
-
-Points to watch:
-
-- The dumper matches the function object by `repr`, so the decorated function must be the exact object
-  placed in the schema. In a factory that returns a new closure per call, decorate the inner function (as
-  `restore_state_schema` and `cv.maybe_simple_value` do), not the factory.
-- The decorator only records anything when extraction is enabled, and that flag is set before imports, so
-  the decorator must run at import time (module level or inside a factory called at module level).
-- A schema chosen per config value (for example by `model`) has no single answer: return a representative
-  schema, as `model_schema_extractor` does.
-- Plain value checks (`cv.All(cv.string, my_check)`) need nothing: the dumper still sees the surrounding
-  types and keys.
-- `cv.Schema`, `cv.typed_schema`, `cv.ensure_list` and the `cv` helpers are already handled; prefer
-  composing them over a custom function, which also avoids the extractor work.

-Build the language schema into a scratch directory and look at the component's JSON (it takes about ten
-seconds):
-
-```bash
-python3 script/build_language_schema.py --output-path /tmp/schema
-python3 -c "import json; print(json.dumps(json.load(open('/tmp/schema/my_component.json')), indent=1))" | less
-```
-
-Every key a user can write should appear under `config_vars` with a sensible `type`; compare against the
-same output from `dev` when changing an existing schema. If the script prints `Unknown extracted schema
-type` or raises, the decorator type or the value returned for `SCHEMA_EXTRACT` is wrong. Unit tests for
-the dumper live in `tests/script/test_build_language_schema.py`.

-description: Test an ESPHome display driver on a real panel with a camera. Use when a task asks to verify a display (LCD, e-paper, OLED, RLCD) on hardware, check orientation/rotation, partial updates, colours, contrast, or that text and shapes render correctly. Covers finding the USB port, flashing a test pattern, capturing the panel with any camera, and reading the photo.

-
-# Display testing with a camera
-
-Point a camera at the panel to get visual evidence that a driver renders correctly. Any camera
-and capture tool works; this skill covers the common ones. `$SKILL` below is this directory
-(`.agents/skills/display-test`).
-
-## Ask before using a camera
-
-A camera can show people and rooms, not only the panel. Before the first capture, ask the user
-for permission and for which camera to use. List the cameras the host has (the commands below
-show how), name the one you intend to use, and wait for the user to confirm it. Do not pick a
-camera yourself, and do not fall back to another camera if the chosen one fails; ask again.
-
-The permission covers this session and the camera the user named. Ask again for a different
-camera or in a new session. If the user declines, stop and report that the display was not
-checked visually.
-
-## Capturing a frame
-
-Grab a still image, skipping the first few frames so auto-exposure and white balance settle.
-Read the JPEG with the Read tool; the image is shown visually.
-
-### macOS
-
-The bundled Swift tool uses AVFoundation and avoids the frame-grabbing problems some USB
-cameras have with other tools:
-
-```bash
-mkdir -p /tmp/camsnap /tmp/display-test
-swiftc -O "$SKILL/scripts/camsnap.swift" -o /tmp/camsnap/camsnap
-/tmp/camsnap/camsnap <camera-name-substring> /tmp/display-test/after.jpg 30
-```
-
-The camera argument is a case-insensitive substring of the name AVFoundation reports. If it does
-not match, the tool lists the cameras it found, so a run with a name that matches nothing lists
-the cameras without capturing. Use a substring that matches only the camera the user approved.
-It creates the output directory if needed and reports encoding or write errors on stderr. Other
-options include `ffmpeg` with `avfoundation` input, `imagesnap`, or Photo Booth's still capture.
-
-### Linux
-
-Use `ffmpeg` with the v4l2 input, `fswebcam`, or `v4l2-ctl`. With `ffmpeg`, `-ss 2` after the
-input discards the first two seconds of frames while exposure settles:
-
-```bash
-mkdir -p /tmp/display-test
-ffmpeg -f v4l2 -i /dev/video0 -ss 2 -frames:v 1 -y /tmp/display-test/after.jpg
-# or
-fswebcam -d /dev/video0 --skip 10 /tmp/display-test/after.jpg
-```
-
-List devices with `v4l2-ctl --list-devices`.
-
-### Windows
-
-Use `ffmpeg` with the DirectShow input (`-ss 2` skips the first frames, as on Linux), or any
-camera application that can save a still image:
-
-```powershell
-mkdir C:\temp -Force | Out-Null
-ffmpeg -f dshow -list_devices true -i dummy   # find the device name
-ffmpeg -f dshow -i video="<device name>" -ss 2 -frames:v 1 -y C:\temp\after.jpg
-```
-
-### Camera caveats
-
-- The board may sit at an angle. Do not trust absolute pixel positions or aspect ratios from the
-  photo; judge orientation, ordering and approximate spacing, using the corner markers as
-  references.
-- Reflections or a glossy cover can brighten one side. Capture again if a region is unclear.
-- A moving pattern is caught at an arbitrary phase. Take several captures, or use a static marker
-  per position.
-
-## Board and port
-
-Find the port; names change on every replug:
-
-```bash
-python3 "$SKILL/../hardware-test/scripts/ports.py"
-```
-
-Native-USB ESP32-S3/C3/C6/H2 boards show up as `USB JTAG/serial debug unit` and need
-`logger: hardware_uart: USB_SERIAL_JTAG`.
-
-## Test pattern
-
-Write a scratch config outside the checkout. Use one `name:` per board and include:
-
-- a white background, a black border and a filled square at the centre, drawn in the first
-  update (full-window check and scale);
-- a 60x20 bar near each corner, one bar per later update with `auto_clear_enabled: false`, so
-  each bar is written by its own partial window. The bars are wider than tall, which shows a
-  90 or 270 degree rotation; the corners exercise the window alignment;
-- a 20x20 square under the left end of the top-left bar, drawn in the same update, which marks
-  the top-left corner and shows a 180 degree rotation or a mirrored image.
-
-Use `Color::BLACK` and `Color::WHITE` in lambdas. Do not use the old `COLOR_OFF`/`COLOR_ON`
-constants; black must mean black.
-
-A ready template is in `$SKILL/templates/display-pattern.yaml`. Substitute the display platform,
-pins and (for a driver with fonts) a font. The marker pattern needs no font.
-
-## Build, flash, capture
-
-Run from the worktree under test so `python -m esphome` imports the checkout, not an installed
-copy:
-
-```bash
-cd <worktree>
-python3 -c "import esphome; print(esphome.__file__)"   # must print the worktree path
-PYTHONUNBUFFERED=1 python3 -m esphome compile /tmp/display-test/display-pattern.yaml
-PYTHONUNBUFFERED=1 python3 -m esphome upload /tmp/display-test/display-pattern.yaml \
-  --device /dev/cu.usbmodemXXXX
-sleep 6   # boot plus a few update intervals
-<capture command> /tmp/display-test/after.jpg
-```
-
-The device path differs by OS and host; use the path printed by `ports.py`. If the USB console
-wedges during flashing (esptool `No serial data received`), replug the board and retry. A board
-powered only by a battery may need the USB cable for flashing; the panel keeps its image when
-power is removed, which is useful for checking that an image is bistable.
-
-## What to check
-
-1. **Orientation**: the extra square sits under the bar in the expected top-left corner. If it is
-   in another corner, the image is rotated or mirrored. Test `rotation:` values with the same
-   pattern. The logical width and height swap at 90 and
-   270 degrees, so the 60x20 corner bars should then appear taller than wide on the physical
-   panel.
-2. **Coverage**: the border touches all four edges, with no dead rows or columns at the edges.
-3. **Partial updates**: with `auto_clear_enabled: false`, draw one marker per update. Each should
-   appear exactly at its requested position with no smearing, offset or mirrored placement.
-   Include all four corners.
-4. **Text and contrast**: sharp glyphs, correct polarity (black text on white, not inverted), no
-   ghosting from the previous frame.
-5. **Speed**: if the driver logs transfer sizes, check that a full refresh and a partial window
-   take the expected times.
-
-Record the build commit, board, config, and the captured image path when reporting results.
-
-## When a partial update looks wrong
-
-Take a marker-only capture before assuming the mapping is wrong: the camera's perspective makes
-absolute positions deceptive. If markers land in mirrored positions, the controller's address
-order (`MADCTL` MX/MY/MV) or the RAM block mapping is inverted for the window; verify the
-full-frame path separately, then fix the window computation.
-
-## Add findings
-
-Add new capture tools, panel quirks, or recovery steps here so the next session starts ahead.

-description: Choose ESPHome C++ containers and storage that avoid heap use and fragmentation on microcontrollers - std::array, StaticVector with cg.slot_list/SLOT_LIST, FixedVector, std::unique_ptr byte buffers, StringRef, RAMAllocator, and what to avoid (std::vector growth, std::map, std::deque, std::string, new (std::nothrow)). Use when adding or changing C++ members, containers, buffers, strings or registration lists, or when reducing RAM or flash use.
----
-
-# Memory on embedded targets
-
-ESP devices run for months with small heaps shared between Wi-Fi, BLE, LWIP, and application code. Over
-time, repeated allocations of different sizes fragment the heap. Failures happen when the largest
-contiguous block shrinks, even if total free heap is still large. We have seen field crashes caused by
-this.
-
-**Heap allocation after `setup()` should be avoided unless absolutely unavoidable.** Every
-allocation/deallocation cycle contributes to fragmentation. ESPHome treats runtime heap allocation as a
-long-term reliability bug, not a performance issue. Helpers that hide allocation (`std::string`,
-`std::to_string`, string-returning helpers) are being deprecated and replaced with buffer and view based
-APIs.
-
-## Container guidelines
-
-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. It does **not** provide bounds checking or iterator support like
-   `std::vector<uint8_t>`; use it only when you do not need these features.
-   ```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;
-   ```
-   When the size comes from the config, declare it with `cg.static_buffer()` in `to_code` and pass the pointer
-   to the constructor, so it lands in BSS (see the `component-codegen` skill).
-
-2. **Compile-time-known fixed sizes with vector-like API:** use `StaticVector` from
-   `esphome/core/helpers.h` for compile-time fixed size with a `push_back()` interface (no dynamic
-   allocation).
-   ```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, no dynamic allocation
-   StaticVector<ServiceRecord, MAX_SERVICES> services;
-   services.push_back(record1);
-   ```
-   Use `cg.add_define("MAX_SERVICES", count)` to set the size from Python configuration.
-
-   **Listener and child-entity registration lists are the most common case, and the most commonly
-   missed.** When the hub only forwards data to its children and each child's handling is known at build
-   time, keep no list at all: use `cg.HubFunction` (see the component-codegen skill). When the hub must
-   store the children (it iterates them for other reasons, or picks fields at run time), a `register_*()`
-   method called once per child at code generation time has a count that is known at compile time, so it
-   should never be a `std::vector`. Declare the list with `SLOT_LIST` and register each child through the
-   call that `cg.slot_list()` returns, passing the hub's `DOMAIN`.
-   ```python
-   # hub component's __init__.py
-   register_listener = cg.slot_list(
-       "MY_COMPONENT_LISTENER_COUNT", "register_listener", DOMAIN
-   )
-
-
-   # a platform of the hub
-   async def to_code(config: ConfigType) -> None:
-       ...
-       hub = await cg.get_variable(config[CONF_MY_COMPONENT_ID])
-       cg.add(register_listener(hub, var))
-   ```
-   ```cpp
-   class MyComponent : public Component {
-    public:
-     SLOT_LIST(MyComponentListener, listeners_, register_listener, MY_COMPONENT_LISTENER_COUNT)
-   ```
-   Do not put `#ifdef` around the macro or the loops over the list. Put `#if MY_COMPONENT_LISTENER_COUNT`
-   only around code that needs a child's own component (its header, its entity type).
-   If registering does more than append, write the method under `SLOT_LIST_REQUIRES(count)` and store into a
-   `[[no_unique_address]] SlotList<Entry, count>` member.
-   If the C++ side adds itself to the list, or the define gates more than the list, use `cg.slot_counter()`
-   keyed by hub (`_request_slot(str(hub))`) and put the storage behind `#ifdef`.
-   Request slots from `to_code`, not from a job that runs after `CoroPriority.FINAL`; a late request
-   raises rather than silently undercounting.
-
-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
-   ```
-   This eliminates `_M_realloc_insert` and `_M_default_append` template instantiations (200-500 bytes per
-   instance), needs no upper bound, and is compatible with protobuf code generation when using
-   `[(fixed_vector) = true]`.
-
-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 is often faster than hashing or tree overhead, but this depends on
-   lookup frequency; in hot paths the O(1) vs O(n) difference may still matter. It is the heavy containers
-   (`map`, `set`, `unordered_map`) that should be avoided for small datasets unless profiling shows
-   otherwise.
-
-5. **Strings set once from configuration:** use `StringRef` (`esphome/core/string_ref.h`) rather than
-   `std::string`. Code generation passes a string literal that lives in flash for the life of the program,
-   so storing a `std::string` copies it onto the heap for nothing. `StringRef` is a non-owning pointer plus
-   length; it does not copy, and it must only ever refer to storage that outlives it (a string literal, or
-   a buffer owned elsewhere).
-   ```cpp
-   // Bad - heap copy of a literal that is already in flash
-   void set_keys(std::string keys) { this->keys_ = std::move(keys); }
-   std::string keys_;
-   ```
-   ```cpp
-   // Good - no allocation
-   void set_keys(const char *keys) { this->keys_ = StringRef(keys); }
-   StringRef keys_;
-   ```
-
-6. **Avoid `std::deque`:** it allocates in 512-byte blocks regardless of element size, guaranteeing at
-   least 512 bytes of RAM usage immediately. This is a major source of crashes on memory-constrained
-   devices.
-
-7. **Never use `new (std::nothrow)`:** on ESP-IDF exceptions are disabled, so a failed nothrow allocation
-   aborts instead of returning `nullptr`. Use `RAMAllocator` from `esphome/core/helpers.h`; CI rejects
-   `std::nothrow`.
-
-8. **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`)
-
-Callback storage (`CallbackManager` vs `LazyCallbackManager`) and templated registration methods are
-covered in the `automations` skill.
-
-## Where to spend effort
-
-Prioritize container optimization for core components (API, network, logger), widely used components
-(mdns, wifi, ble), and components causing flash size complaints. Avoiding heap allocation after `setup()`
-is always required regardless of component type; the priority list is about effort spent on container
-migration (e.g. `std::vector` to `StaticVector`).

-# Hardware testing
-
-The goal of a hardware test is evidence a reviewer can trust: which build ran on which board, what was
-driven, what the logs show, and the same flow on a `dev` build when a quirk could be pre-existing.
-`$SKILL` below is this directory (`.agents/skills/hardware-test`).
-
-## Ground rules
-
-1. **Serial ports cannot be shared.** One bounded capture per port, stopped before any flash on that
-   port, never an open-ended `esphome logs`. Stop a capture with `pkill -f "[s]erial_capture.py <port> "`,
-   naming the port so a capture on another board survives; the bracket keeps the pattern from matching
-   the shell that runs it. When more than one agent session shares the bench, run a copy of the script
-   under a session-specific name (`cap<topic>.py`) so another session's `pkill` cannot take your capture
-   down. Never run `esphome logs` in a `while true` loop: the loop respawns it and holds the port.
-2. **Credentials stay local.** Put a `secrets.yaml` next to the scratch configs and reference it with
-   `!secret`. A copy of a device's own config keeps using the secrets file next to that config: two
-   checkouts can hold different networks, and the wrong one leaves the device unreachable after the OTA. Never paste a config with credentials into a PR, never commit scratch configs or logs.
-3. **Build from the tree under test.** `python -m esphome` puts the current directory first on
-   `sys.path`, so run it with the checkout or worktree as the working directory and pass the yaml by
-   its absolute path. A venv `esphome` entry point may import an installed snapshot instead of the
-   checkout. Confirm with `python -c 'import esphome; print(esphome.__file__)'`, and for an A/B grep
-   the build's `src/` for the change before trusting any number. Tool calls sent together share one
-   shell, so a `cd` in one can land another's compile in the wrong tree: pass `PYTHONPATH=<worktree>` on
-   every compile and upload command and print `esphome.__file__` into the compile log.
-4. **PR build and baseline build get different `name:` values.** Builds share
-   `.esphome/build/<name>`, so the same name means `esphome upload` can flash the wrong binary. Saved
-   Wi-Fi credentials are keyed by the config hash when the config has `networks:`, so a test that must
-   start unprovisioned gets a fresh name every run. A config with `ap:` only and no `networks:` uses one
-   fixed key shared by every such config on the board, so a new name does not help there: wipe once at
-   boot with an `on_boot` lambda that resets the preferences and saves a marker key
-   (`templates/dut-ap-only-wipe-once-bk72xx.yaml`).
-5. **Flash and RAM deltas are measured against the PR's merge base** (`git merge-base origin/dev HEAD`
-   checked out in a throwaway worktree), with the baseline commit named in the table. When a delta
-   looks odd, diff symbol sizes (`nm -S -C --size-sort` from the matching toolchain) before quoting it.
-   When a change moves storage between the heap and static RAM, the static number alone misleads: also log
-   the free heap at the end of setup (`on_boot` at priority -100) over three boots of each build and report
-   the total in use (static RAM plus heap used).
-6. **Prove a quirk is pre-existing before blaming the PR:** run the identical flow on a `dev` build in
-   the same session and say so in the results.
-7. **Pipe safely.** Set `PYTHONUNBUFFERED=1` on any `esphome run` or `esphome logs` whose output is
-   piped, or lines land minutes late. Bound every long command with `timeout` (coreutils) or
-   `perl -e 'alarm shift; exec @ARGV' <seconds> <command>` on macOS without it. Save an exit code with `rc=$?`
-   right after the command: in `echo "$(date +%T) rc=$?"` the command substitution runs first and `$?` reads 0.
-
-## Workflow
-
-1. **Find the boards:** `python $SKILL/scripts/ports.py` (any Python with pyserial, for example the
-   ESPHome venv). Port names follow the USB hub port and change on every replug, so never reuse a name
-   from an earlier session. CH340 adapters (D1 mini, BW15 kit, BK7238, CB3S) all look the same; tell
-   them apart with a 10 s capture using `serial_capture.py --reset` (ESP8266 prints its ROM banner at
-   74880 baud, LibreTiny boards print `[LT]` and ESPHome lines, BK7238 prints its bootloader version).
-   `ports.py --wait 2e8a` blocks until a Pico re-enumerates.
-2. **Make a scratch directory** outside the checkout, with `secrets.yaml` and the templates you need.
-   One yaml per board per variant, file name equal to `name:`.
-3. **Compile** in the right tree:
-   `(cd <worktree> && PYTHONUNBUFFERED=1 timeout 1500 python -m esphome compile <abs yaml> > <name>-compile.log 2>&1)`.
-   Keep the RAM and flash lines at the end. Two ESP-IDF or two LibreTiny builds at the same time race
-   over tool caches; run them one at a time.
-4. **Flash** per chip family (table below). Stop the capture on that port first.
-5. **Capture** with `serial_capture.py PORT SECONDS OUT` in the background, then poll the file with
-   `grep` in an `until ... sleep 2` loop with a cap. USB CDC boards (Pico, nRF52, native USB ESP32)
-   drop the port on reboot; the script reopens it until its deadline.
-6. **Drive** the test: a second board running a client config, `curl`, an aioesphomeapi script that
-   presses a template button and subscribes to logs, MQTT publishes, or `interval:` and `on_boot:`
-   automations in the config itself.
-7. **Analyze** with `grep -a -c` counts over the capture and keep an `-events.txt` extract of the lines
-   that matter. Decode crashes with the platform's `addr2line` (see `reference/boards.md`).
-8. **Report** on the PR. Every result comment starts with this two-line GitHub alert, then a blank line:
-
-   ```
-   > [!NOTE]
-   > Automated testing results
-   ```
-
-   Then one short sentence saying what was tested (builds and SHAs, board, what was driven), a results table
-   (build SHA, board and framework, what was driven, counts, result, plus the `dev` control row), short bullets
-   for the findings, and the setup and exact flow in a collapsed `<details>` block. Answer any question asked on
-   the PR directly in the comment. No credentials, SSIDs, IP addresses, port names or other bench details.

-## Flashing by chip family
-
-| Board | Flash | Log |
-|---|---|---|
-| ESP8266 D1 mini (CH340) | `python -m esphome upload <yaml> --device <port>` | `serial_capture.py` at 115200; `esphome logs` on some CH340s emits garbage after the RTS reset. A failed esptool write can wedge the adapter until the board is replugged. `esptool erase_flash` before a test that needs an unprovisioned device: the preference sector survives a reflash |
-| ESP32 devkit (CP2102 or CH340) | `esphome upload --device <port>`, ESP-IDF or Arduino | `serial_capture.py`. Default Wi-Fi light sleep delays API driven actions by seconds; judge timing from device logs. `power_save_mode: none` for OTA overlap tests |
-| ESP32-S3, C3, C6, H2 native USB | `esphome upload --device /dev/cu.usbmodem*` | `logger: hardware_uart: USB_SERIAL_JTAG`. The USB console can wedge when the app takes over the console (0 bytes, esptool `No serial data received`); replug, or watch through `esphome logs --device <name>.local` |
-| Pico W / Pico 2 W | `esphome upload --device <port>` (1200 baud touch); first flash ever via BOOTSEL and `--device /Volumes/RPI-RP2` or `RP2350` | port re-enumerates after upload: `ports.py --wait 2e8a` then capture |
-| BW15 kit (RTL8720CF, rtl87xx) | `~/.platformio/penv/.libretiny/bin/python $SKILL/scripts/flash_rtl87xx_kit.py flash write -d <port> <build>/.pioenvs/<name>/*.uf2`. Plain `esphome upload` and plain ltchiptool time out because opening the port asserts DTR/RTS and holds the chip in reset | `serial_capture.py --released`, never `esphome logs` |
-| BW12 and other AmebaZ modules (RTL8710BX, rtl87xx) on a plain USB-UART | `~/.platformio/penv/.libretiny/bin/python -m ltchiptool flash write -B 115200 -b 115200 -t 120 -d <port> <uf2>`, started first, then strap by hand: CEN to GND, TX2 to GND, release CEN, release TX2. Without `-B 115200` the system data read at 1.5 Mbaud fails on CH340s (`Data read error at 0x9000`) and nothing is written. A 1 MB image takes about 80 s. A development board with DTR and RTS wired to CEN and the download pin needs no strap | `serial_capture.py`; a reset pulse does not reach CEN on a plain adapter, so a capture starts mid-run |
-| BK7238 / CB3S (bk72xx, RTS on CEN) | `~/.platformio/penv/.libretiny/bin/python $SKILL/scripts/flash_bk72xx.py flash write -d <port> <uf2>` (about 75 s) | logs are on UART2 by default; `logger: hardware_uart: UART1` puts them on the flashing adapter. `serial_capture.py --reset` gives a chip-enable reset; a plain open may or may not reset it, check for the bootloader banner |
-| LN882H | ltchiptool forces 1 Mbaud for writes; weak adapters need `LN882H_YM_BAUDRATE` patched to 115200 in the penv's `ln882htool.py`; short BOOT to GND while the tool connects | OTA after the first flash |
-| nRF52840 Dongle (PCA10059) | Nordic `nrfutil nrf5sdk-tools dfu usb-serial` on the bootloader port, or `dfu: true` in the config so the 1200 baud touch pin-resets into the bootloader; adafruit-nrfutil is refused | app has two CDC ports, ESPHome log on the second |
-| Adafruit-style nRF52 (UF2 bootloader) | `UF2BOOT` volume or adafruit-nrfutil; `dfu: true` works through GPREGRET | single CDC port |
-| Any reachable device | `esphome upload <yaml> --device <ip or name.local>`; `--file <bin>` for a prebuilt image | `esphome logs --device <ip>` bounded with `timeout` |
-
-ESP-IDF OTA image: `.esphome/build/<name>/build/firmware.ota.bin`. LibreTiny OTA port is 8892.

-## Scripts in `$SKILL/scripts`
-
-- `ports.py`: list ports with VID:PID, product, serial and a board guess; `--wait VID[:PID]`,
-  `--product NAME`, `--serial SN` (one specific board, whatever path it comes back under) and
-  `--serial-of PORT` (the serial number behind a path).
-- `serial_capture.py PORT SECONDS OUT [--baud] [--released] [--reset] [--append] [--ms]`: bounded timestamped
-  capture (`--ms` adds milliseconds for timing work), ANSI stripped, `LOG_SECRET` text written as `<secret>`, reopens a vanished port, exits at the
-  deadline. OUT is truncated unless `--append` is given, so counts over it cover one run.
-- `flash_rtl87xx_kit.py`: ltchiptool wrapper for the BW15 kit whose CH340 drives CEN (RTS) and the boot
-  strap (DTR). `flash read` needs the family `realtek-ambz2`; `flash write` does not.
-- `flash_bk72xx.py`: ltchiptool wrapper for BK72xx boards whose RTS drives CEN. It misses the link now
-  and then; retry up to three times.
-- `api_button.py HOST KEY list|press NAME [...]`: list a device's template buttons or press them over the API; the
-  recipes drive their test configs with it.
-- `apiconn.py`: `connect(host, tries)` (API connect and login with retries, `API_KEY` from the env) and `log_text()`
-  (an API log line without ANSI codes), imported by the newer API drivers.
-- `wifisave_hammer.sh KIND DUT_PORT DUT_YAML DUT_TREE CLIENT_PORT CLIENT_YAML CLIENT_TREE [SETTLE]`:
-  the fallback AP plus captive portal hammer end to end (compile, flash, capture, counts) with the
-  templates below. KIND is `esp`, `pico`, `bw15` or `bk`. It ends with `RESULT PASS` (exit 0),
-  `RESULT FAIL` (exit 3: a crash, a reboot after the AP came up, or the device never joined the network),
-  `RESULT INVALID`
-  (exit 2: a precondition was missed, the stimulus was insufficient, or a capture did not last the run)
-  or exits 1 when a build, flash or port step failed.

-## When the PR keeps moving
-
-Record every head in the stack (`gh pr view N --json headRefOid`), build, and recheck before flashing; if anything
-moved, wait five minutes and check again so the test runs on a settled head. When a head moved only by merging dev,
-compare the PR's own diff (`git diff $(git merge-base OLD origin/dev) OLD` against the same for NEW); if it is
-identical and the dev commits do not touch the code under test, earlier results still describe it, but rebuild so the
-comment quotes the exact commits. Fetch `origin dev` before computing a merge base.
-
-## When something looks wrong
-
-- A capture stopped early or a line is missing: check the timestamps before trusting it.
-- A script that pipes into `tee` never ends although its work is done: a background command written as
-  `(cd dir && server & echo $!)` backgrounds the whole `cd && server` list, so a shell stays behind holding the
-  pipe open and `$!` is that shell, not the server. Write `(cd dir && exec server > out 2>&1 < /dev/null) &`.
-- The client never joins the AP: another board may still run an AP with the same SSID, or the device
-  booted with saved credentials because the name was reused. One AP device at a time on the bench.
-- Builds come out byte-identical between branches: the wrong tree was imported (rule 3). The reverse
-  too: two binaries that differ only in the build timestamp and in `__LINE__` values of log calls below
-  the changed code are the same build; map the offsets with `objdump -h` and `addr2line` first.
-- A boot the host cannot capture (a power cut, an OTA-only board): keep the boot report in a flash
-  preference and repeat it in a periodic alive line, as `scripts/libretiny_prefs/ltprefs.hpp` does.
-- Multicast from the host never arrives on some access points: test it device to device. Broadcast
-  is lossy under Wi-Fi power save, unicast is not. Throttle UDP floods to a fixed packet rate.
-- The merge base comes from a freshly fetched `origin/dev`; a stale local `dev` puts dependency bumps into the
-  PR diff and builds the control from the wrong commit.
-- A `.local` name can stop resolving in the middle of a run; keep the address from the boot log and drive by it.
-- Never point `framework: source:` at a local `file://` copy of LibreTiny to try a patch: PlatformIO installs it over
-  the shared `~/.platformio/platforms/libretiny`, so every later build on the machine uses the patched copy. Patch
-  through the ESPHome side (a linker `-Wl,-wrap,<symbol>` or a define) instead, and if it happened, restore the
-  directory from a clean copy of the same release.
-- `wc -l` pads its count on macOS, so `tail -n +$n0` needs `$((n0+0))` or an arithmetic expansion.
-- `api:` reboots a board after 15 min without a client: `reboot_timeout: 0s` on `api:` and `mqtt:` for
-  soak tests.

-
-## ESP8266 (D1 mini, NodeMCU, CH340 or CP2102)
-
-- Opening the port usually resets the board through DTR, but not always; `serial_capture.py --reset`
-  pulses RTS to capture from boot. 74880 baud shows the ROM boot messages (`rst cause`, `boot mode`).
-- UART0 can be looped back onto itself (`USC0(0) |= (1 << UCLBE)` in an `on_boot` lambda) so a UART
-  component is testable without its device: frames written with `uart.write` arrive on RX. Log over the
-  API with `logger: baud_rate: 0`, since the serial port carries the component's bytes.
-- `esphome logs` on some CH340s emits thousands of duplicated garbage lines right after the RTS reset;
-  a plain pyserial capture at 115200 is reliable.
-- A failed esptool write can wedge the adapter (`termios` error 22, or an open that hangs) until replug.
-- The preference sector survives a reflash: a provisioned API key or saved Wi-Fi credentials stay
-  active. `esptool erase_flash` gives a clean device.
-- `Panic core_esp8266_main.cpp:191 __yield` with `ctx: sys` means a yield from lwIP context (a web
-  handler, an lwIP callback). Decode stacks with
-  `xtensa-lx106-elf-addr2line -e <build>/.pioenvs/<name>/firmware.elf -f -C -i <addr...>` from the
-  toolchain under `~/.platformio/packages/toolchain-xtensa/bin/` (PlatformIO builds) or the ESPHome
-  cache directory (native toolchain builds).
-- Constant data lives in RAM unless marked `PROGMEM`; with 80 KB of RAM a few hundred bytes are worth a
-  row in the PR.
-- AsyncMqttClient drops inbound topics over 128 characters; topics of 255 or more wrap a counter and
-  stall the link until the broker drops TCP.
-
-## ESP32 classic devkit
-
-- Takes ESP-IDF and Arduino. Default Wi-Fi light sleep delays API driven actions by up to 6 s; judge
-  timings from device logs, not from the host. `power_save_mode: none` for OTA overlap tests (an IDF web
-  upload of 739 KB took 107 s with power save and 45 s without).
-- Receives only a few percent of IPv6 multicast on some access points with power save on; a raw lwIP
-  socket loses the same, so that is the AP or driver, not a PR.
-- Decode with `xtensa-esp32-elf-addr2line` from the IDF tools directory against
-  `<build>/.pioenvs/<name>/firmware.elf` (PlatformIO) or `<build>/build/<name>.elf` (IDF native).
-- Clean reboot between runs with the capture stopped: `esptool --after hard_reset chip_id`.
-- Trigger a forced crash only after the app is marked valid (45 s after boot is plenty), never on an
-  image still pending OTA rollback.
-- Signed OTA testing: build with `esp32.framework.advanced.signed_ota_verification.verification_keys`
-  under a different name, sign with `python -m espsecure sign_data --version 2 --keyfile
-  tests/components/esp32/dummy_signing_key.pem`, upload with `esphome upload --file`. The verifier
-  refuses unsigned images afterwards, so restore with a signed plain build.
-- An ESP32 whose bootloader has no app rollback is protected only by `safe_mode` after a bad OTA. Before sending a
-  change to such a device that nobody can reach by hand, boot the same code on a devkit first and keep a fallback
-  image of the merge base built.
-
-## ESP32-S3, C3, C6, H2 with native USB
-
-- `/dev/cu.usbmodem*`, esptool works, `logger: hardware_uart: USB_SERIAL_JTAG`.
-- The USB console can die at the moment the app takes over the console during a reboot (log stops after
-  `Disabling RNG early entropy source`, then 0 bytes, esptool reports `No serial data received`). Only a
-  USB replug fixes it. Fallback: `esphome logs --device <name>.local` (API log stream, which drops lines
-  while Wi-Fi is off).
-- The ESP32-P4 before silicon revision 3 is bricked by rev3-only firmware (boot loop at bootloader entry). The
-  Waveshare ESP32-P4-WIFI6 rev1.3 board is such pre-rev3 silicon.
-- S3, C3 and C6 all enumerate as `303a:1001`; confirm the chip with `esptool --port <port> chip_id` before flashing.
-- ESP32-C6 test configs: set `wifi: power_save_mode: none`. With the default light sleep, API commands and state
-  updates arrived seconds late and a 1.2 s step check failed at random on base and PR alike (esphome#22339).
-- An S3 on Arduino with `logger: hardware_uart: USB_CDC` enumerates as TinyUSB CDC (`303a:0009`). If that build
-  crash loops (a FastLED plus NeoPixelBus build aborts in `check_rmt_legacy_driver_conflict`), esptool cannot catch
-  the port: hold BOOT, tap RST, keep BOOT held about 2 s, then flash with `--before no-reset`. A plain RTS hard reset
-  leaves it in the loader on USB JTAG; `--after watchdog-reset` boots the app. Keep Arduino LED tests on the classic
-  ESP32.
-- A board left in the ROM bootloader after an upload (BOOT held, or the USB JTAG reset landing in download mode
-  again) starts its app without a replug through `esptool --port <port> --after watchdog-reset chip-id`; flash a
-  minimal Wi-Fi plus API image first when recovering from a crash-looping one.
-
-## RP2040 / RP2350 (Pico W, Pico 2 W)
-
-- The CDC port re-enumerates after every reboot and after `esphome upload` (1200 baud touch). Re-detect
-  with `ports.py --wait 2e8a` before capturing; `serial_capture.py` reopens on its own if the port
-  vanishes mid-capture.
-- First flash ever: BOOTSEL, then `esphome upload --device /Volumes/RPI-RP2` (or `RP2350`).
-- arduino-pico creates the lwIP netif in `WiFi.begin()`, so any IGMP join during component setup fails;
-  joins must wait for `network::is_connected()`.
-- Parallel Pico builds race on package extraction after a PlatformIO package wipe; one at a time.
-- An RTS pulse from pyserial does not reset the board; reboot with `App.safe_reboot()` or the touch.
-- LEAmDNS re-enters `update()` from the receive handler on the Pico too (measured), so an ESP8266-only guard does
-  not cover it.
-- An image with only `ota: platform: web_server`, built from a tree without the fix for uploads of unknown size
-  (before 2026-10-19), cannot be updated again over the network; see `recipes/ota.md` before flashing one.
-- RP2350 `panic()` goes through `_exit()` and `__breakpoint()` to a HardFault, and ESPHome's rp2 crash handler
-  reboots within about a second (USB back 1 to 2 s after the panic). A panic during component setup therefore
-  boot-loops before USB CDC ever enumerates, which looks like a dead board: no port and no BOOTSEL drive. Recover
-  with BOOTSEL held on replug, then flash to the `RP2350` volume. To see the crash, trigger it after boot.
-- A Pico 2 W can sample any of its own GPIOs from a spare PIO block (PIO2) at 25 MHz while another peripheral
-  drives the pin, since PIO reads the pad without taking it. That decodes WS2812-style pulses with no wires or
-  LEDs. Turn a light on at full brightness before probing, or color correction writes zeros. The sample FIFO
-  overruns now and then; count only full captures.
-- A Pico 2 W also makes a byte-exact fake I2C sensor: a raw RP2350 I2C0 interrupt handler (GP4/GP5) that answers
-  each RD_REQ with one byte from a 256-byte register file, so any read length works (used for BME280/BMP280 in
-  esphome#22236). The ESP32-S3 I2C slave v2 driver is not usable for register emulation: answering from a task or
-  straight from the interrupt both gave shifted multi-byte reads.
-
-## BW15 kit (RTL8720CF, LibreTiny rtl87xx)
-
-- The kit's CH340 wires RTS to CEN and DTR to PA00 (boot strap). A plain pyserial open asserts both and
-  holds the chip in reset, which is why `esphome upload`, plain `ltchiptool` and `esphome logs` all fail
-  ("Timeout while linking", or silence). `scripts/flash_rtl87xx_kit.py` sets DTR high and RTS released
-  on every open, pulses RTS once so the ROM answers `ping`, and after the command drops DTR and pulses
-  RTS to boot the app. Run it with the PlatformIO LibreTiny penv Python.
-- `flash write -d <port> <uf2>` takes no family argument; `flash read -d <port> -s 0 -l <len>
-  realtek-ambz2 <out>` does.
-- Capture with `serial_capture.py --released`. The ESPHome log is on the flashing UART already.
-- The macOS CH340 driver only pushes DTR/RTS to the wire once a session has driven them, so the first
-  plain open after a replug streams logs and the second is silent; always open with the lines released.
-- Driver quirks seen on `dev`: `WiFi.begin` can refuse the real network on the first try after bogus
-  credentials (it connects after two cooldowns); right after connecting while the AP is still up the
-  driver can bus-fault in `rtw_is_adapter_up` (`R0 = 0xdeadbeef`) and reboot; the AP restarts on every
-  STA retry, so stations cannot stay joined; `WiFi.begin` fails synchronously for an absent network and
-  lands in a cooldown at once; connecting blocks the loop 2.5 to 4.1 s.
-- Decode faults with `arm-none-eabi-addr2line -e <build>/.pioenvs/<name>/raw_firmware.elf -f -C -i <PC>`
-  from `~/.platformio/packages/toolchain-gccarmnoneeabi/bin/` (`raw_firmware.elf`, not `firmware.elf`).
-  Fault dumps print PC, LR and R0 to R3.
-- The AmebaZ2 SDK sets `LWIP_TCPIP_CORE_LOCKING 0`.
-- The `rtw_is_adapter_up` bus fault after `Disabling AP` happens on LibreTiny 1.13.0 and 1.14.0 alike
-  (2 of 4 and 3 of 3 runs in #21531); run at least four rounds per build before blaming a PR for it.
-- On a fault the ROM handler (ram_vector_table entries 3 to 7) prints a dump of about 4 KB in 0.4 s and
-  then spins; only the watchdog resets the chip (10 s after `arch_init`, 1 s once the ESPHome crash
-  handler re-arms it). `.ram.bss.noinit*` (`.system_restore_data`) survives that reset. The core has no
-  FPU. For a crash that fires once, guard an `interval` lambda with
-  `!libretiny::crash_handler_has_data()`. For a handler mode (MSP) fault, point vector 16+11 (SDIOD,
-  unused) at a trapping function and set bit 11 in NVIC ISER and ISPR (0xE000E100, 0xE000E200).
-- OTA slots (esphome#22012): a serial `ltchiptool flash write` fills both OTA1 and OTA2, and the slot flag decides
-  which one boots (`OTA1 USE` or `OTA2 USE` in the ROM banner). Each OTA writes the other slot, so a test that needs
-  the OTA1 to OTA2 direction runs two OTAs in a row. On dev before #22111 a deflate OTA into OTA2 corrupted the
-  image, and the next restart hung at `System_Init1` until a serial reflash.
-- If the chip still waits in the ROM after a serial flash, pulse CEN to GND once (TX2 floating) to boot the app.
-  `expected ACK` failures at random blocks mid-transfer can come from one USB hub port; another port fixed them.
-- Its Wi-Fi is slow and drops (esphome#21742): a 300 KB deflate OTA takes 3 to 10 minutes, so give the uploader 30
-  minutes, not 10.
-- Wrong-MD5 OTA test without changing firmware: monkeypatch `espota2.hashlib.md5` so only the image checksum (data
-  over 64 KB) returns a wrong hexdigest. Give each build its own `name:` and read `device_info().name` after a
-  restart to see which image booted.
-
-## BK7238, WB3S, CB3S (BK7231N) (LibreTiny bk72xx, CH340, RTS on CEN)
-
-- Stock ltchiptool closes and reopens the port after its reset, and pyserial raises both lines on open,
-  holding CEN low through the BootROM window. `scripts/flash_bk72xx.py` opens with both released and
-  pulses the reset right before the link checks. A write takes about 75 s. Only a CEN or power reset
-  reaches the downloader; no software reboot does.
-- ESPHome logs on UART2 by default; `logger: hardware_uart: UART1` puts them on the flashing adapter.
-- Opening the port may reset the chip (bootloader banner on open) or may not, depending on the adapter and
-  what pyserial does with DTR and RTS; `serial_capture.py --reset` pulses RTS on CEN and always does, and
-  `lt_get_reboot_reason()` reports that as Power-On. Check for the banner at the start of a capture before
-  assuming either.
-- `flash_bk72xx.py` misses the link now and then (`Timed out attempting to link with chip`); retry up to 3
-  times before suspecting the board.
-- Crashes: `__builtin_trap()` and a call into unmapped memory both end as an undefined-instruction trap
-  (`bk_misc_get_start_type()` 6, `lt_get_reboot_reason()` Crash); reads, unaligned loads and stores to
-  unmapped addresses never fault on the ARM968. Without Wi-Fi the SDK trap handler spins with interrupts off
-  for 10 s and the hardware watchdog resets the chip. With Wi-Fi connected a dev build hangs forever after a
-  crash, and never resets from a plain `portDISABLE_INTERRUPTS(); while (1) {}` either: the boot-time
-  watchdog is dead once Wi-Fi is up, for any lockup. The crash handler fix (#21012) re-arms the watchdog
-  from its wrapper, after which the reboot comes within a second (BK7238 and BK7231N).
-- The SDK prints nothing on UART1 under `sdk_silent: all`; the bootloader then prints the banked
-  `cpsr/spsr/r13/r14` of SVC, IRQ, FIQ and SYS plus `ST:` (the retention register) before `go os_addr`.
-  A CEN or power reset wipes ITCM (reads `0xaaaaaaaa`), so only a watchdog reset keeps a record there. What
-  survives that reboot on the BK7238: ITCM (`0x3F0000..0x3F4000`) and the top 96 KB of SRAM
-  (`0x428000..0x440000`, the heap); the bootloader zeroes SRAM up to about `0x420000` and rewrites
-  `0x400024..0x4000FF` with its own register dump every boot, so neither a `.noinit` after `.bss` nor the
-  SDK's saved register banks are usable. Code is compiled Thumb, the SDK assembly is ARM; in an exception
-  handler only r0 to r3 are shared by all modes. BK7231N ITCM is `0x3FEE00..0x400000` (4.5 KB); a `.noinit`
-  placed there after `.itcm.code` works for a crash record.
-- Pick the board that matches the module's flash layout. A NiceMCU XH-WB3S (BK7238) needs `board: xh-wb3s` (plain
-  Beken layout, RF calibration at 0x1E0000). Built as `generic-bk7238-tuya` (calibration at 0x1E3000, download
-  partition over 0x1E0000) the firmware boots and may even join a known network, but scans come back empty and its
-  AP is invisible to clients, with no warning in the log. If scans are empty, check the layout first.
-- The BK7238 bootloader prints `App verify failed! Need to recovery factory firmware.` on every boot with any
-  build; it is harmless. Even with the right layout an ESP32 client did not see the BK7238 fallback AP on
-  LibreTiny 1.13.0 or 1.14.0, so the wifisave hammer cannot run on it.
-- Moving a BK7231N device (CB3S) that sits on its fallback AP to another network: join the host's Wi-Fi to
-  `<name>-fallback`, OTA to 192.168.4.1, then rejoin the host's own network. Moving it with `/wifisave` instead can
-  leave it in the captive portal's BLIND_RETRY state (no scan, `Beacon Timeout` every 46 s) until it reboots, and a
-  log-only serial adapter cannot reset it. Rejoining may change the host's address; update a syslog target that
-  points at the old one.
-- Callbacks run on the `async_tcp` task and log lines can lose a byte. Wi-Fi connect takes tens of ms;
-  radio enable 160 to 278 ms, disable about 200 ms.
-- OTA install: the BK7238 bootloader installs any complete download whose own CRC passes at the next restart, even
-  when ESPHome refused the update; an incomplete download fails `rt_ota_part_fw_verify` (`Verify firmware CRC32
-  ... !=`) and the old image stays.
-- Power save: on the BK7238, `power_save_mode: light` with LibreTiny 1.14.0 gives ping times of 3 to 6 s because
-  the BDK sets a listen interval of 30 beacons when `CFG_LOW_VOLTAGE_PS` is 1 (esphome#19491).
-
-## BW12 and other AmebaZ boards (RTL8710BX, LibreTiny rtl87xx)
-
-- On a bare module wired to a plain USB-UART (the bench's BW12), download mode is a hand strap: CEN to
-  GND, TX2 to GND, release CEN, release TX2. Such an adapter does not drive CEN, so neither ltchiptool nor
-  `serial_capture.py --reset` can reset the chip. A development board that wires DTR and RTS to CEN and the
-  download pin enters download mode from the tools, like the BW15 kit; the notes below on baud rates still apply.
-- ltchiptool links at 1.5 Mbaud and reads the system data at 0x9000 at that rate before it writes at
-  115200. A CH340 drops bytes there (`Data read error at 0x9000`, `Timed out waiting for Quiet-Handshake`)
-  and the run gives up without writing. `-B 115200 -b 115200` moves the link to 115200 first and works.
-  Start the command with `-t 120` so it is already polling while the board is strapped.
-- After a failed run the ROM may sit at another baud rate and no longer link; strap again.
-- The device builder frontend's AmebaZ flasher follows ltchiptool (link and system read at 1.5 Mbaud),
-  so it can hit the same read failure on the same adapters.
-- Power the module from the adapter's 5 V pin into its own regulator; the adapter's 3.3 V pin cannot
-  carry the Wi-Fi transmit peaks.
-- Capture with `serial_capture.py --released`. With DTR and RTS asserted on the open port, a software
-  reboot (`App.safe_reboot()`, the restart button) lands in the ROM downloader (`UARTIMG_Download 2`)
-  and stays there until CEN is pulsed. After a flash the chip also waits in the ROM until CEN is pulsed.
-- A full flash takes 50 to 220 s at 115200. While the board is on Wi-Fi, OTA (port 8892) saves the strap,
-  but the board's Wi-Fi latency (one to two seconds a ping) can make the upload time out.
-- `sdk_silent: none` under `framework:` keeps the Wi-Fi driver's join log (`start auth to`, `auth success,
-  start assoc`, `association success`, `sta recv deauth reason code(N)`); LibreTiny mutes it during the
-  connect otherwise. `wifi_get_last_error()` after a failed `WiFi.begin()` gives the SDK's reason
-  (1 no network, 2 connect failed, 3 handshake failed, 6 auth failed); LibreTiny only logs `ret=-1`.
-- Some modules ship with no RF calibration in efuse, only the chip ID and MAC. Dump the logical map with
-  the ROM's `EFUSE_LogicalMap_Read(buf)` (512 bytes): TX power indexes are at 0x10 to 0x1A, crystal trim
-  at 0xC9, MAC at 0x11A; 0xFF means the driver uses its default (trim 0x20). Linking with
-  `-Wl,-wrap,EFUSE_LogicalMap_Read_ACUT` lets a wrapper rewrite blank bytes before the driver parses
-  the map on each radio start. See `recipes/libretiny.md` for the per-boot trial harness used to A/B them.
-- Scan results report WPA2-AES access points as `WPA PSK`: LibreTiny truncates `rtw_security_t` to
-  `uint8_t` before mapping it. Cosmetic. Open networks come out as `WIFI_AUTH_INVALID` (255) on both
-  AmebaZ and AmebaZ2, so `auth != WIFI_AUTH_OPEN` marks them encrypted.
-- After a BSSID plus channel join, LibreTiny's `set_pscan_channel(ch, false)` leaves the driver with no
-  channel to scan, so the next SSID only join fails at once (no `start auth`), and the first scan after a BSSID
-  join comes back empty (no results in about 62 ms on the BW15). A `wifi_set_pscan_chan` list of channels 1 to 13
-  returns 0 but leaves only the last channel enabled, and re-applying the channel plan does not help either
-  (AmebaZ2 reports plan 0xFF; AmebaZ's `rtw_set_chplan_cmd` rejects plans above 0x58 except 0x7F). What works
-  (esphome#21749, BW15): set the one-channel pscan list yourself and pass channel 0, so the join's own scan
-  rebuilds the full list; setting a placeholder SSID `-` before narrowing (esphome#21754) kept joins as fast as
-  dev with the first scan full on every boot. Not yet confirmed on AmebaZ.
-- A 4-way handshake that never finishes after association is reported as `RTW_WRONG_PASSWORD` on AmebaZ
-  even with the right password; AmebaZ2 reports a real wrong password as a 4-way handshake timeout.
-- The driver also posts a SCAN_DONE (number 0) inside every join, on AmebaZ2 too.
-
-## BW16 kit (RTL8720DN, AmebaD)
-
-- The kit's own USB-C (CH340) is on LOG_UART and flashes fine. Its two-transistor circuit resets while
-  RTS alone is asserted and straps BURN while DTR alone is; both asserted does nothing. ROM entry is
-  esptool's classic sequence (`dtr:false,rts:true` 100 ms, `dtr:true,rts:false` 400 ms, both false); the
-  first pulse after a replug can be lost, retry up to three times.
-- Any reopen resets the chip, 460800 is flaky, 115200 is solid: one open per session, in-place baud
-  changes only. The ROM and the loader NAK continuously while idle, so ACK scans must drain first.
-- The AmebaD core has no mDNS responder (`mdns: disabled: true`).
-
-## LN882H
-
-- ltchiptool forces 1 Mbaud for writes; adapters that cannot hold it fail with "Timeout while linking"
-  or die mid-write. Patch `LN882H_YM_BAUDRATE` in the penv's `ltchiptool/soc/ln882h/util/ln882htool.py`
-  to 115200 (lost on reprovision). Weak 3.3 V from the adapter: feed the module's 5 V pad instead. Short
-  BOOT to GND while the tool connects. OTA afterwards.
-- `USE_WIFI_AP_EXCLUSIVE` (one radio mode at a time) exists only on LN882x; compile-check changes there.
-- The ESPHome OTA port on LN882x is 8820, not LibreTiny's 8892 (BK72xx, RTL87xx); helper scripts that hardcode
-  8892 get `Connection refused`.
-- WL2H-U modules with the Tuya flash layout: app at 0x007000 (0x113000 long), OTA at 0x11A000 (0xA8000 long). A
-  full OTA upload over a slow link takes 2 to 14 minutes.
-- UF2 block order differs per family: LN882H puts the device image first and the flasher image after it, BK72xx
-  puts the flasher image first and the device image last. The LN882H bootloader installs a complete, valid OTA
-  partition even when the upgrade state is still `UPG_STATE_DOWNLOAD_ING` (esphome#22111).
-- Without serial access to recover, never send a corrupted image; wrong-MD5 and cut-upload tests with valid
-  images are safe.
-
-## nRF52840
-
-- Nordic PCA10059 dongle: the factory Open DFU bootloader enumerates as `1915:521F` on its own port
-  name; the app as `2FE3:0100` with two CDC ports, ESPHome log on the second. Only Nordic
-  `nrfutil nrf5sdk-tools` works (`pkg generate --hw-version 52 --sd-req 0x00 --application-version 1
-  --application zephyr.hex app.zip`, then `dfu usb-serial -pkg app.zip -p <port>`); ESPHome downloads
-  it on the first build. GPREGRET does not enter the bootloader; a pin reset through P0.19 does, which
-  `dfu: true` wires up on this board. A pulsing red LED means bootloader; the side RESET button
-  re-enters it.
-- Makerdiary MDK USB dongle: UF2 bootloader without SoftDevice, app at 0x1000, `UF2BOOT` volume,
-  adafruit-nrfutil, GPREGRET 0x57 works. The running app enumerates as `1915:CAFE` or `239A:0029`. RGB LED
-  active low (red P0.23, green P0.22, blue P0.24), button P0.18.
-- Both boards reflash without a button once they run a `dfu: true` build: `esphome upload --device <any app CDC
-  port>` on the PCA10059, a 1200 bps open of the log port plus a copy of `zephyr.uf2` to the volume on the ItsyBitsy.
-- Adafruit ItsyBitsy nRF52840 Express (UF2 bootloader 0.9.0 with S140 6.1.1, bootloader port `239a:0051` plus an
-  `ITSY840BOOT` volume): the board DTS already has `cdc_acm_uart0`, so the logger port is the first CDC
-  port and a `usb_cdc_acm` interface 1 the second. A `dfu: true` build enters the bootloader on the
-  1200 bps touch (an app without it needs a double tap on RESET); `adafruit-nrfutil` over the bootloader
-  serial port can fail, copying `.pioenvs/<name>/zephyr/zephyr.uf2` to the volume works (the copy reports
-  an I/O error as the board reboots, which is normal). Reboot a running `dfu: true` app with a 2001 bps touch.
-- The PCA10059 board DTS already defines a `cdc_acm_uart` node, so every ESPHome CDC port is one USB port
-  later than its number (log on `cdc_acm_uart0` is the second port). A third CDC instance needs
-  `CONFIG_USB_MAX_NUM_TRANSFERS` above 4 or it never moves data (see `recipes/usb_cdc_acm.md`).
-- USB CDC boot output: the Zephyr legacy stack's `cdc_acm` TX ring is 1 KB and `uart_poll_out` drops when it
-  is full, so anything printed in one burst beyond about 1 KB (a coredump, a long table) is lost even with
-  the port open, and the logger warns `logger took a long time`. Print one line per `loop()` instead.
-- Zephyr settings survive a reflash: key a `restore_value` global by a `run` substitution when a test needs
-  a never-saved value.
-- Thread: nRF52 `openthread:` accepts only `tlv:`; the individual keys (network_key, channel, ...) are rejected at
-  validation. To list nearby networks with channel and PAN ID, call
-  `otThreadDiscover(InstanceLock::acquire().get_instance(), 0, 0xFFFF, false, false, cb, nullptr)` from an
-  `interval:` lambda in an included header; results arrive on the OpenThread thread and log fine.
-- A wrong network key on a real network's channel and PAN ID makes the device form its own partition as leader on
-  that PAN within about 30 s; take it off Thread at once. Never try guessed datasets against a network in use.

-## Waveshare ESP32-S3-ETH with the OV5640 camera module
-
-- Native USB console (`303a:1001`), ESP32-S3R8, 16 MB flash, 8 MB octal PSRAM, W5500 on SPI (MOSI 11,
-  MISO 12, SCLK 13, CS 14, INT 10, RST 9), TF card on 4..7, WS2812 on 21.
-- Camera header (vendor schematic): XCLK 3, SIOD 48, SIOC 47, VSYNC 1 (a 0 ohm link to GPIO1, alternative
-  GPIO16), HREF 2, PCLK 39, D0..D7 = 41, 45, 46, 42, 40, 38, 15, 18. PWDN is tied to GND and RESET is an RC to
-  3.3 V on the board, so no reset or power-down GPIO exists.
-- It can run from PoE and USB-C at once, so the USB-C can move from the host to a USB device for `usb_uart` or USB
-  host tests while the board stays up; flash and read logs over Ethernet while it is unplugged. In USB host mode
-  the USB-C is the host port after the first flash: log over the API with `logger: hardware_uart: UART0`.
-- A crash-looping image can wedge its USB console until a BOOT replug. Never force allocation failures on it by
-  hogging RAM: Wi-Fi then aborts in `operator new` or the loop task trips the task watchdog.
-- GPIO8 switches the camera 3.3 V rail through a P-channel MOSFET: LOW = camera powered, gate pulled up so
-  the camera is off by default. `power_down_pin: GPIO8` only pulls it low 10 ms before the probe, which is
-  not enough; use `switch: gpio GPIO8 restore_mode: ALWAYS_OFF setup_priority: 800` plus `on_boot:
-  priority: 700` with `delay(1200)` and `esp32_camera: setup_priority: 200`
-  (`templates/rtsp-waveshare-s3-eth-dut.yaml`). `esphome config` rejects a config that uses GPIO8 for both the switch
-  and `power_down_pin` (pin reuse), so it is one or the other.
-- The sensor at SCCB 0x3C answers only with XCLK running, so the ESPHome i2c scan at boot (before XCLK)
-  reporting no devices on 48/47 is expected. If the SCCB ID register (0x3100 = 0x78) reads fine but every
-  0x30xx register reads 0x00 (`Detected camera not supported`, 0x106), reseat the ribbon before blaming
-  software; `templates/waveshare-s3-eth-camdiag.yaml` runs that probe with LEDC XCLK and raw SCCB reads.
-
-## ESP Thread Border Router board v1.2 (S3 host + H2 RCP)
-
-- S3 host on USB JTAG serial, H2 RCP on its own USB. Spinel UART1 from the host: `rx_pin: GPIO17`,
-  `tx_pin: GPIO18`, RCP reset `GPIO7` active low, 460800. The config needs `network: enable_ipv6: true`.
-- The shipped H2 firmware fails `CheckRadioCapabilities` with IDF 5.5; build `examples/openthread/ot_rcp`
-  for esp32h2 with ESPHome's own IDF (`IDF_PATH` at the cached framework, its penv and tools,
-  `IDF_PYTHON_CHECK_CONSTRAINTS=no`) and flash with esptool at 0x0, 0x8000 and 0x10000.
-- A crash-looping S3 pulses the H2 reset every boot, so the H2 cannot be flashed and the S3 will not
-  enter its bootloader over USB. Hold S3 BOOT, tap S3 RST, flash the H2, release, then replug both.
-- `dns-sd -L <name> _meshcop._udp local.` shows the `omr` prefix; it disappears when routing is dead.
-  Keep one capture per chip; never reset the H2 over USB mid-test unless that is the test (the host
-  logs `Unexpected RCP reset: RESET_OTHER` and recovers).
-
-## Building against a patched LibreTiny
-
-- Clone LibreTiny at the tag ESPHome pins, commit the patch, and set `framework: version: <tag version>` plus
-  `source: file://<clone>` under `bk72xx:` or `rtl87xx:`. PlatformIO installs it as
-  `~/.platformio/platforms/libretiny` (the stock copy is `libretiny@src-<hash>` and is not touched).
-- A later commit in the clone is not picked up by the next build; patch the installed copy or remove it. Remove
-  `~/.platformio/platforms/libretiny` when done.
-- BDK headers such as `power_save_pub.h` have no `extern "C"`; wrap them when including them from the Arduino
-  core's C++ files.
-
-## LibreTiny crash and abort() facts (esphome#21596, #22288)
-
-- `abort()` on dev: the BK7238 hangs for good (the main loop stops and the watchdog never fires once Wi-Fi is up;
-  recover with an RTS pulse on CEN, `serial_capture.py --reset`). The BW15 (RTL8720CF) restarts with no crash
-  record. The LN882H reboots only after about 18 s through the watchdog (`WDT Reset`), with no record: the SDK's
-  `abort()` and `_exit()` (`components/libc/newlib_stub.c`) and its FreeRTOS `configASSERT` are spin loops. With
-  #22288 all three reboot in 1 to 2 s and log `Reason: Abort`, with the PC at the call site and no `LR:` line.
-- `assert()`, `std::terminate` and a failed `new` all reach `abort()` (nano libsupc++). `raise(SIGABRT)` returns,
-  because `_kill` is a nosys stub.
-- `__builtin_trap()` faults on every board. A store to `nullptr` or 0xDEADBEE0 does not fault on the BK7238. On
-  the BW15 a `nullptr` store does not fault, and loads and stores at 0xDEADBEE0 give only imprecise bus faults
-  (CFSR 0x400, no BFARVALID), so testing the fault address path needs another Cortex-M chip.
-- BK7238 safe mode: each quick crash reboot counts toward it (`Last reset too quick; invoke in N restarts`), so
-  back-to-back crash tests can drop the board into safe mode.
-- LN882H: the previous crash is replayed to every new API log client until the next crash; that is expected, not a
-  double record. Once, the first `__builtin_trap()` after a fresh OTA took about 12 s to reboot; retries took 2 to
-  3 s and it did not reproduce.
-- `~/.platformio/packages/toolchain-gccarmnoneeabi` can vanish between a build and the decode (it comes back with
-  the next LibreTiny build). Until then the `arm-none-eabi-addr2line` and objdump of
-  `toolchain-rp2040-earlephilhower` read any ARM ELF.
-- RTL8720C: a noreturn `bl abort` can be the last instruction of a function, so the raw return address points at
-  padding addr2line cannot place. Decode `(addr & ~1) - 2` to get the call line; #22288 records it that way.
-- Abort reports (#21596): early heads put LR 0x00000000 first in the address list; later heads drop a zero LR, so
-  an abort report starts with the backtrace.

-## Waveshare ESP32-C6-GEEK
-
-- Native USB JTAG serial (`303a:1001`), 16 MB flash, 1.14" ST7789 LCD and TF card; the vendor docs give no GPIO
-  numbers. Pins that read a fixed level against the internal pulls: 1, 2, 7, 20, 23 high, 6 low. Free for pad

-## Waveshare ESP32-P4-Module-DEV-KIT (USB host)
-
-- ESP32-P4 rev v1.3, 16 MB flash, console on a CH343 (`1a86:55d3`). Other boards use the same chip for their
-  console, so check with `esptool chip_id`.
-- USB host for `usb_host`: set the Host/Device jumper to HOST and use the bottom USB-A port nearest the Ethernet
-  jack (the high-speed OTG controller); the other USB-A ports and the USB-C marked "USB" do not reach it. The ports
-  are unlabelled. The port powers the device.
-- ESP-IDF programs the FIFO split only when a device connects: read `GRXFSIZ`, `GNPTXFSIZ` and `HPTXFSIZ` at
-  `DR_REG_USB2_BASE` + 0x24, 0x28 and 0x100 after enumeration. GHWCFG3 (0x4C, high 16 bits) reads 896 lines. The
-  default split is RX 512, NPTX 256, PTX 128.
-- Not every P4 board has a USB host port; check before planning a `usb_host` test on one.
-
-## Gelidus Research PS1 v2.3 (LD2420 presence sensor)
-
-- ESP32-D0WD-V3 rev 3.1 on a CH340 (`1a86:7523`); `esphome upload --device <port>` works directly.
-- LD2420 UART: TX GPIO17, RX GPIO16, 115200 (radar firmware v1.6.1). Status LED GPIO23, night light PWM on GPIO25.
-- The vendor package is at github.com/GelidusResearch/grps (`packages/grps-ld2420.yaml`); copy it locally for tests.
-- The radar needs a person in its field. Energy frames are `F4 F3 F2 F1 23 00 <presence> <range cm LE16> ...`; a
-  UART `debug:` block on RX shows them.
-
-## ESP32-C3 Super Mini (native USB, 4 MB XMC flash)
-
-- Shows up as `303a:1001`; confirm with `esptool --port <port> chip_id`. Board `esp32-c3-devkitm-1`,
-  `logger: hardware_uart: USB_SERIAL_JTAG`. Avoid GPIO2, 8 and 9 (strapping; 8 is the LED, 9 is BOOT).
-- A 6-pin BME680 breakout (CS, ADDR/MISO, SCL, SDA, GND, VCC) on SDA GPIO6 and SCL GPIO7 with CS and ADDR left
-  open answers at 0x77 through the breakout's pull-ups, and the `bme680` platform reads fine.
-- BME688 parallel mode never reads in `bme68x_bsec2` on dev: the read timer is re-armed by each 30 ms run before
-  its 41.6 ms delay ends. Entering parallel mode at all needs gas estimates subscribed at `BSEC_SAMPLE_RATE_SCAN`
-  and no IAQ outputs.
-
-## mDNS responder tests (#22267)
-
-- When the host's multicast does not reach the device, query its port 5353 directly as legacy unicast (a
-  python-zeroconf packet sent from a normal UDP socket) to dump records or hammer the responder.
-- On a crowded Wi-Fi channel, back-to-back query loss swung from 0 to 14% between builds for no code reason. Judge
-  responder timing on an Ethernet board.
-
-## nRF54LM20 DK (PCA10184, on-board J-Link)
-
-- The power switch must be ON or nothing enumerates. The ESPHome log (uart20) is on the second J-Link VCOM port;
-  the first is unused.
-- Flash with `esphome upload <yaml> --device JLINK` (sdk-nrf toolchain); the LM20 needs no west `--device` override.
-  The J-Link re-enumerates after the flash, so start the capture after the port comes back.
-- Reset without halting: JLinkExe `-device NRF54LM20A_M33 -if SWD -autoconnect 1` with `w4 0xE000ED0C 0x05FA0004`
-  (plain `r` and `g` halt and resume, no reboot).
-- LED0 P1.22, LED1 P1.25; BUTTON0 P1.26, BUTTON1 P1.09, BUTTON2 P1.08, BUTTON3 P0.05 (active low, pull-up). GPIO
-  P1 registers at 0x500D8200 (IN +0x00C, PIN_CNF +0x080), P0 at 0x5010A200.
-- Binary sensor state changes are not logged at DEBUG; log the states or count `on_press` to see button presses.

-length delimited strings and `int[]` as repeated sint32 (field 7); `ALLOW_MISSING=1` leaves arguments out on purpose
-(the device then drops the call). `templates/api-actions-dut.yaml` (D1 mini, three actions, optional variables with
-defaults) and `templates/api-actions-strings-dut.yaml` (required strings) log what arrived. String arguments are

-# Injecting BLE GAP and GATTC events (#21698)
-
-Some BLE paths (repeated connection parameter update failures, a disconnect in the middle of them) are hard to get
-from a real peer on demand. `scripts/ble_event_inject` feeds made up events straight into the ESP32 BLE handlers.
-
-- `ESP32BLE::gap_event_handler` and `gattc_event_handler` are protected statics and the class is `final`.
-  `cp_inject.hpp` reaches them through explicit template instantiation, where access checks do not apply. Its
-  `cpinject::run()` sends six labelled steps (`STEP1` to `STEP6`): four peers failing five times each, a success
-  followed by more failures, and disconnects between failures.
-- `cp-inject.yaml` is a package for a copy of a proxy config: it adds the include, a VERBOSE logger with the busy
-  tags back at DEBUG, and an `Inject conn param events` button. Press it with `scripts/api_button.py` while a
-  log capture (`esphome logs ... --device <ip>` under `timeout`) runs, then count the warning and verbose lines per
-  step on the PR and on dev.
-- The handlers push into a queue and event pool that take a single writer, normally the Bluetooth task. Injecting
-  from the main task while real events arrive can corrupt them, so the button stops the scan, waits for it to end,
-  injects and starts it again. Run it with no active proxy connections (no Home Assistant BLE client holding one).
-- Fake disconnects use `gattc_if` 0xFE: every client and proxy connection filters on its own `gattc_if_`, so the
-  queued event reaches only the shared handler. Do not use 0xFF (`ESP_GATT_IF_NONE`), which every client accepts.
-- The fake peers (`C0:FF:EE:00:00:0n`) are never connected, so a live proxy keeps serving its real connections;
-  put it back on its own config afterwards.

-# esp32_ble_server pairing and encrypted characteristics (#17562)
-
-`scripts/ble_server_security`: a classic ESP32 devkit runs the secure GATT server (`server.yaml`) and a second ESP32
-(an S3 here) runs `ble_client` as the central (`client.yaml`). The server has a `read_encrypt` battery level
-(`99.9`), a plain characteristic, a `write_encrypt` characteristic that logs what it receives, a `read_encrypt_mitm`
-characteristic and a `read_encrypt` characteristic that notifies every 2 s. `run.sh TAG IO AUTH` builds both with the
-pairing mode as substitutions, pairs once, reconnects twice, and `summary.py` prints PASS or FAIL. The server needs
-`esp32_ble_server` security from #17562 or later: point `SERVER_TREE` at that checkout (the client builds from
-`TREE`, dev is fine). `summary.py` needs each refused read to show an `Error reading char` reply, so a run where the
-client never connected fails instead of passing.
-
-- `ble_client` never starts pairing on its own (a phone does, after an `insufficient authentication` reply); the
-  client's `Pair` button calls `BLEClientBase::pair()`. Read errors show as `Error reading char at handle N, status=5`
-  (not authenticated: no bond) or `status=15` (not encrypted: bond known, link not encrypted yet).
-- The `ble_client` text sensor subscribes once, at connect, before any pairing, so a protected characteristic refuses
-  it. The `Subscribe` button writes the CCCD again after pairing; `ble_client` drops its service list after discovery,
-  so it writes the characteristic handle + 1 (where ESP-IDF's GATT server puts the CCCD).
-- Numeric comparison (`display_yes_no` with `sc_mitm_bond`) tells a fresh pairing from a bond reuse: the
-  `numeric comparison` line only appears on a fresh pairing. Just Works cannot show it.
-- ESP-IDF 5.5.6 drops the bond on the second disconnect on both roles (`Deleting unpaired device`), so that reconnect
-  pairs from scratch; 5.5.5 keeps it (`-s idf 5.5.5`).
-- The server keeps its bonds in NVS. One holding an authenticated bond for the client refuses a Just Works re-pairing
-  silently; erase the devkit's flash before switching from nc to jw.
-- `summary.py` failed both modes at 58636914ab: `read_encrypt_mitm` was readable with no pairing, because
-  `BLEService::create_characteristic()` took an 8 bit `esp_gatt_char_prop_t` and dropped the MITM bits (1 << 8 and
-  1 << 9). Check the generated `create_characteristic` call and the property type when a flag above bit 7 is added.

-comparison accepted automatically) and a classic ESP32 devkit runs `esp32central-cli.yaml` (`ble_client` with

-`bonds.hpp` logs the bond list Bluedroid loaded from NVS on both boards.

-- The server never starts pairing (a peripheral only answers a security request), and `ble_client` does not start
-  it on an insufficient authentication reply (status 5) the way Android does. The client's `on_connect` calls
-  `esp_ble_set_encryption(remote_bda, ESP_BLE_SEC_ENCRYPT_MITM)` instead.
-- `esp32central-flow.sh TAG` erases both boards, flashes them, captures a fresh pairing with three link cycles
-  (phase A), then resets both together so each loads its bond (phase B), and prints per phase the connects, numeric
-  comparisons (a fresh pairing), MITM reads, server writes and `Deleting unpaired device` lines. It passes when

-## Held GATT link after a half-open API session (#21256, #22077)

-When Home Assistant stops answering without closing its socket, the proxy must not keep the BLE link it opened for
-that session. `scripts/bluetooth_proxy_half_open/` reproduces it with:
-- `proxy.yaml`: the proxy under test on a classic ESP32 devkit (ESP-IDF, VERBOSE logger with the busy tags at DEBUG,

-  (`esp32_ble_server` takes one client by default), with manufacturer data `FF FF 21 56` so the client can find it.
-- `ha.py`: the Home Assistant stand-in (aioesphomeapi, `client_info` "Home Assistant test"). Roles: `owner` connects
-  to the peripheral through the proxy and idles, `observe` counts the peripheral's adverts and the slot report and can
-  ask for a connect at the end, `swap` connects at once and retries on the first advert. Every role stays subscribed
-  to advertisements: with no subscriber the proxy's loop disconnects every link at once, which hides the bug (an
-  early run failed with `disconnect while backend idle` for that reason).
-
-`cases.sh PROXY_HOST LABEL` (env `PROXY_PORT`, `PERI_PORT`, `SC`, `PY`, `API_KEY`) captures both boards and runs
-case C (old client killed, new client after 4 s), case H (old client frozen with `SIGSTOP`, so the socket stays open
-with no FIN; new client after 4 s, watched 300 s, then it asks to connect and releases) and case N (frozen and nobody
-reconnects for 200 s). `cases.sh PROXY_HOST LABEL swap` instead repeats H three times with the new client
-connecting at once (`ha.py ... swap ADDR`) and retrying on the first advert. Both end with PASS or FAIL: the cases
-fail when an observer exits non-zero, never sees the peripheral advertise (the held link) or the proxy resets, and
-swap fails when a round never connects. An owner that never got the link also fails (a rig problem, not a result).
-
-- The proxy drops a frozen session as unresponsive after about 144 s.
-- Before #22077, case H holds the link for good: 0 adverts, and the address stays in the slot report. With #22077 the

-# Fake I2C devices without a chip

-## Fake devices on an in-firmware I2C bus
-
-When there is no chip and no wiring, subclass `i2c::I2CBus` in an include, implement `write_readv()` only, answer
-the registers the driver reads and check each write. Point the component at it from an `on_boot` lambda that runs
-before the component's `setup()`: `id(x)->set_i2c_bus(&fake::bus)` at priority 950, which is ahead of every I2C
-component (hubs set up at IO, 900, sensors at DATA, 600). The configs here that use 700 to 1000 work for their
-components; use 950 for a new one. Keep a real `i2c:` block in the config so validation passes. Bulk
-loops in a button lambda must call `App.feed_wdt()` and keep their per-iteration logs below INFO: 2000 DEBUG lines at
-115200 baud trip the task watchdog, which is a fault of the harness and not of the PR.
-
-`templates/i2c_fake/` holds the fakes; each `*-common.yaml` or `*-test.yaml` is a classic ESP32 or ESP32-S3 config
-that includes its `.hpp` (add `esphome: name:` for the `-common` ones):
-- `ccsfake.hpp`, `ccs-common.yaml`: CCS811 at 0x5A (#21927). Answers setup and update reads and checks every
-  ENV_DATA write against the humidity and temperature the case set; "CCS Cases" runs edge values, "CCS Sweep" 2000
-  random ones and logs `SWEEP checked N bad M bad_reads R bad_writes W`. A read without a register, of a register
-  the fake does not model or of the wrong length gets a NACK and counts in `bad_reads`; a write other than the
-  driver's SW_RESET, APP_START, MEAS_MODE and BASELINE writes (each with its own length) gets a NACK and counts in
-  `bad_writes`. The CASES and SWEEP lines end in PASS only when something was checked and `bad`, `bad_reads` and
-  `bad_writes` stayed 0, and in FAIL otherwise.
-- `eefake.hpp`, `ee-common.yaml`: HTE501 (0x40) and TEE501 (0x48) with CRC words; "Next" steps through raw
-  temperature words and logs the value a signed hundredths decode should give (#21930). A command other than
-  identification and measure, and a read longer than the reply, gets a NACK and counts as `bad`. The DONE line
-  200 ms later, after both reads, shows the running `bad` total, the measure replies each driver read and the
-  published values; it ends in PASS only while `bad` is 0, both drivers read a reply this case and both published
-  the expected temperature (and HTE501 the fixed humidity).
-- `scdfake.hpp`, `scd-common.yaml`: SCD4x at 0x62 and 0x63 with Sensirion CRC; logs every `0xE000` ambient pressure
-  write, and the CASE and SHOW lines count writes with a bad CRC apart from the good ones. A command the scd4x driver
-  does not send, one sent with the wrong length (2 bytes bare, 5 bytes with one CRC word), or any other command with a
-  bad CRC, gets a NACK and counts as `bad writes`. A read after a command the fake does not answer, or one longer than the command's
-  reply, gets a NACK and counts as `unknown reads`. The second instance has a fixed `ambient_pressure_compensation`
-  to cover the setup path (#21935). Each CASE line ends in PASS only when bad CRC, bad writes and unknown reads did
-  not move, the `0xE000` writes match `expect_e000()` (none, or one with the expected value) and, for a source case,
-  CO2 was published. `RANGE_CHECKED` in `scdfake.hpp` picks the rule: false truncates as dev does, true skips values
-  outside 700 to 1200 hPa and rounds as #21935 did. The SHOW line ends in PASS when nothing bad was counted, neither
-  instance failed and 0x63 got exactly one write of its fixed value.
-- `sxfake.hpp`, `sx-common.yaml`: two SX1509 register files with reset values and the `7D 12/34` reset, recording
-  every write. Only a byte that lands on RegReset (0x7D) drives the reset, so a burst through it keeps the bytes for
-  0x7E and 0x7F. A read without a register, or a transfer past 0x7F, gets a NACK and `dump_log()` warns with the
-  count. Compare per address: hub setup order can legitimately move between hubs (#21897). Outputs of an Apply
-  platform are distinct template types, so a lambda list of them needs
-  `std::initializer_list<output::FloatOutput *>{...}`. Each case ends with an END line, PASS only while no write was
-  dropped and no transfer was bad; the writes themselves are judged by the diff.
-- `msfake.hpp`: eight MS8607 pressure/temperature fakes at 0x76 and up and humidity fakes at 0x40 and up, with faults
-  per device (reset NACKs, bad PROM CRC4, zero D1 every Nth read, humidity CRC8 errors, out of range D2, full scale
-  humidity). It counts every command, so skipped conversions show in `report()`, and an ADC read with no conversion
-  pending answers 0 like the real chip and counts as `adc_no_conv`, and a humidity read with no measure pending gets
-  a NACK like the real chip in no-hold mode and counts as `read_no_measure` (a reset aborts either); each injected
-  fault counts when it is delivered (`inj_reset_nack` with `reset_nack_left`, `inj_zero_d1`, `inj_bad_crc`), so a
-  run that never reached a fault path shows 0 there; a PROM read, conversion or humidity measure
-  before that device's first reset counts as `no_reset`; a humidity read of any shape but a bare
-  3 byte read, and a pressure/temperature read that is not a 2 byte read of a PROM word (even addresses 0xA0 to 0xAC) or
-  a 3 byte ADC read, gets a NACK and counts as `bad_reads`; a bare read answers the last PROM or ADC pointer and never
-  repeats a reset or conversion; a command write the fake does not know, or one longer than a
-  byte, gets a NACK and counts as `bad_cmds`. Point both the component and its `humidity_i2c_id` device at the bus. That
-  driver logs no values, so give each sensor an INFO `on_value` log (#16487).
-- `htfake.hpp`, `ht16k33-char-test.yaml`: HT16K33 chips at 0x70 to 0x77 (0x74 and 0x76 NACK) keeping the 16 byte
-  display RAM and a command trace, rendered back as text for the Adafruit 0.56" 7-segment backpack ("12:34",
-  decimal points, "!" for stray bytes); a read gets a NACK and counts as malformed. The test runs 64 checks (setup order, font, colon and dots, chained chips,
-  printf/strftime/clock, dimming, blink, standby, NACK) and ends with `ALL DONE pass=N fail=M` and PASS or FAIL (#8520). It found a
-  crash (null glyph table) when one display had `add_characters` and another did not.
-- `ssfake.hpp`, `seesaw-test.yaml`: Adafruit seesaw at 0x36 (ATtiny817), 0x49 (SAMD09) and 0x4A (NACK): status,
-  GPIO bulk with the pull latch, ADC, touch, encoder and NeoPixel with chunk offsets, and the write to read gap per
-  module. A read it does not model, a write without a register and a write to a module or register it does not model
-  (or with the wrong data length) get a NACK and count in `bad`. A 100 ms interval step machine drives it and ends with `ALL DONE` and PASS or FAIL (#13538).
-- `bldcfake.hpp` (three M5Unit-BLDC units at 0x65 to 0x67 with simple motor physics, one that never spins down),
-  `gtfake.hpp` (GT911 at 0x5D: switches, max values, touch points and key byte) and `sdpfake.hpp` (SDP3x/SDP8xx at
-  0x21 to 0x26: product IDs, an unknown product, a failing read every third time, a failing ID read, stop refused
-  while idle) have no config yet; wire them the same way. Each fake sets up its own faults in its constructor, so
-  there is no init step to call. Each NACKs a read it does not model or one of the wrong
-  length, and a write or command it does not know, and counts them as `bad_reads` and `bad_writes` (`bad_cmds` for
-  the SDP) in `report()`; check those are 0. The SDP report also counts each injected ID read NACK at 0x24 as
-  `id_fail`, so 0 there means the driver never reached that fault.

-## Pico 2 W as an I2C target (#22236)
-
-`scripts/pico_i2c_target/`: `picofake.hpp` is a raw RP2350 I2C0 interrupt handler on GP4 (SDA) and GP5 (SCL) at 0x76 that
-answers one byte per read request from a 256 byte register file, so any read length is byte exact. `picofake.yaml`
-plays a BME280 (`chip_id` 0x60) or BMP280 (0x58) with the datasheet calibration; every 15 s it switches between the
-datasheet example readings and the 0x80000 "no measurement" values, and logs `STAT` counters every 5 s. `bad`
-counts reads and writes of registers the drivers do not use (soft reset only with 0xB6, read pointer wrapping past
-0xFF). The DUT is
-an ESP32-C3 (`dut-common.yaml`, GPIO6/GPIO7) with two sensors on the one fake (`dut-bme280.yaml`,
-`dut-bmp280.yaml`), the second with oversampling NONE. `run.sh bme280|bmp280 LABEL` flashes the DUT, starts the
-fake capture and waits for a `STAT` line as the baseline, then resets and captures the DUT and prints the distinct
-values per sensor. The fake capture runs on until a `STAT` line arrives after the DUT capture ends, so that line
-covers the whole run. It prints PASS when every sensor gave a numeric state, that `STAT` line came, and the fake's
-`abrt` (read replies the controller aborted) and `bad` counts did not move from the baseline; diff the output of dev
-and the PR.
-
-The ESP32-S3 I2C slave v2 driver cannot emulate a register device: answering from a task and straight from the ISR
-both gave shifted multi-byte reads. Use the Pico.
-
-## DS2482-800 simulator (ds248x)
-
-`scripts/ds248x_sim/`: `dssim.yaml` with `sim.hpp` turns a Pico 2 W into a DS2482-800 at 0x18 (GP4 SDA, GP5 SCL)
-with four DS18B20s: channel 0 at 21.5 °C, channel 1 at 33.0 °C, channel 2 at -5.25 and 40.0 °C. The DUT is an
-ESP32-C3 (`dspd.yaml`, GPIO4/GPIO5 plus GND); the internal pull-ups are enough at 50 kHz. Faults are one character
-on the Pico's USB console: `c` NACKs the read pointer write after the next channel select, `z` NACKs the 9 reads
-after the next 0xBE, `b` and `k` stick busy with a failed reset or config write, `x` and `X` make it dead and alive.
-`SC=<serial_capture.py> python3 drive.py TAG SIM_PORT DUT_PORT [c,cd,z,b,k,dead]` (default `c,z,b,k,dead`; `cd`
-runs the `c` fault densely, 28 times about 3 s apart) resets the DUT per phase and prints
-readings, wrong values, log counts and the simulator's counters (`wrong_ch` counts ROM matches on the wrong
-channel). The DUT is captured with `--ms` so the log can be split at the last fault: the recovery window starts
-`SETTLE` (3) seconds after it. A phase fails when any of the four sensors got no correct reading in the recovery
-window, the DUT logged a CRC, held low, busy timeout or no response line in it, a temperature is wrong, a phase other
-than `dead` logged `recovery failed`, `DS248x hub failed` or a component marked failed, a ds248x warning is still
-set at the end of the phase, the DUT capture
-failed (stderr in `TAG-<phase>.err`), a fault moved its injection counter (counted when the DUT meets the
-fault, not when it is armed) by other than the number of faults sent (`arm_lost` counts arms that landed while one
-of the same fault was still pending and merged into it), a NACK fault never moved `nacked`, a write delivered data while a NACK was armed
-(`nack_miss`, also counted when the write is followed by a repeated start into a read; the NACK never reached the wire and stays pending), the DUT sent an address-only write (`empty_wr`), a write was cut off by a repeated start into another write and
-never processed (`dropped`),
-a fault is still pending (`pend=1`) at the end of the
-phase, the simulator counted a config write with a wrong complement (`cfg_bad`) or an unknown, short or overlong
-command (`bad_cmd`), a counter is missing from the simulator's CNT line, the simulator aborted a read reply
-(`tx_abrt`, not gated in the `dead` phase, which switches the controller off), a phase other than `b` and `k` (which
-reset the chip under the driver) counted `wrong_ch` or a 1-Wire command without the active pull-up bit (`ops_no_apu`),
-the simulator never logged `DEAD` for the `dead`
-phase, or the DUT log of the `dead` phase has no sign of the outage (`did not respond`, a ds248x warning,
-`DS248x hub failed` or a component marked failed). It ends with PASS or `FAIL:` and the failed phases. The whole
-phase CRC, held low, busy timeout and no response counts are printed for information: the faults cause them.
-
-- Sensors polled at the same interval go through the channels in blocks, so a stale channel cache never shows.
-  Poll them at different intervals, as `dspd.yaml` does (1, 1.3, 1.7 and 2.3 s).
-- The NACKs use the RP2350 `slv_data_nack_only` register, set at STOP.
-- A NACKed write and an address-only write both end with no data, so the simulator cannot tell them apart.
-  The ds248x driver never sends one, `dspd.yaml` sets `scan: false` and the simulator only sees STOPs after its
-  own address, so `empty_wr` (address-only writes outside a NACK window) stays 0; a nonzero count means `nacked`
-  may include writes that never carried a NACKed byte.
-
-## I2C fault injection in software (vl53l0x)
-
-`scripts/i2c_fault/`: `faultbus.h` wraps the real `I2CBus` and returns NACK for chosen transfers to one address. An
-`on_boot` priority 800 lambda swaps the sensor's bus (`id(d)->set_i2c_bus(&fb)`) before its setup, and an interval
-arms the faults. `vlpf.yaml` runs a VL53L0X on an ESP32-S3 (GPIO8/GPIO9) through quiet, fault A (the next
-measurement-in-progress read fails), quiet, fault B (the next measurement start fails) and quiet phases over 150 s,
-with a model ID probe every 10 s to tell a driver stall from a dead chip. `run.sh LABEL` builds, flashes, captures
-and runs `an.py`, which counts readings per `PHASE` line. Each `PHASE` line clears a fault that was armed and has
-not fired yet and logs the fired totals so far, so `an.py` counts the fires of each phase. It fails when the phases are not quiet, faultA, quiet,
-faultB, quiet (a short capture or a restart), the first quiet phase has no readings, a later quiet phase reads less
-than half as often as the first, a later quiet phase reads NaN (`nan` or `-nan`) or logs the driver's "update called before prior
-reading" warning when the first did not (a target out of range reads NaN in every phase), a quiet phase has a failed
-model ID probe, one that did not return 0xEE or no successful probe at all,
-anything crashed or rebooted, or a fault did not fire in its own phase or fired in another one.
-
-Prefer this to glitching the wire. Holding SDA low by rerouting the pin (`esp_rom_gpio_connect_out_signal` to
-`SIG_GPIO_OUT_IDX` and back to `I2CEXT0_SDA_OUT_IDX`) wedges the ESP-IDF controller, which then needs
-`i2c_master_bus_reset()` after each glitch, and glitches timed onto writes left the VL53L0X answering 0x00 until a
-power cycle.

-# HTTPS on web_server_idf (#22185)
-
-#22185 adds an HTTPS developer API to `web_server_idf` with no YAML option, so `scripts/https_idf/` brings a test
-component: `ext/httpstest` (`httpstest.hpp`) serves `/hw` (a status line with mode, request count and free heap),
-`/hw/big` (16 KB) and `/hw/switch/{http,https,https8443,bad}`. A switch runs on the main loop through `defer()`, or
-3 s later with a `/later` suffix (a stalled TLS client holds the server task, so its switch is armed first), and
-calls `set_ssl_credentials(cert, key, port)`: plain HTTP on 80, HTTPS on 443 or 8443, or a key that does not match
-the certificate. Its schema uses `web_server_idf.consume_ssl_sockets`. The run-time switch is the follow-up API; on a
-tree that only has #22185, drop the switch paths and set the credentials once before `init()`.
-
-Copy the directory into a scratch directory with a `secrets.yaml`, then `run.sh LABEL` (env `TREE`, `PORT`, `SC`,
-`PY`): it runs `make_certs.sh` (a self-signed P-256 certificate, its key and an unrelated key in
-`ext/httpstest/certs.h`; test material, never commit it), builds `https-dut.yaml` (ESP32-C3, logs on USB), flashes,
-takes the address from the serial log and runs:
-- `t1.sh HOST`: one GET with the TLS time, 20 sequential, 6 parallel three times and the 16 KB body. The fixture has
-  no event source, so the 501 that #22185 sends for an event stream on HTTPS is not covered here.
-- `stall.py HOST`: arms a switch to HTTP and to 8443, opens two idle TCP clients (no ClientHello) on 443 before it
-  runs, then switches back; every switch must be accepted and work, and the idle clients must be closed.
-- `t2.sh HOST`: HTTP and back, an armed switch to 8443 with a client open that sends a handshake record header and
-  never the rest, 60 requests that must all get a 200 for a heap check (compare the `/hw` heap before and after),
-  then the bad key. The server must log the error and stay off, without falling back to plain HTTP; reset the board
-  afterwards.
-
-The runner fails on any unexpected status, a missing key error for the bad key, a reset or a task watchdog. `https-soak.yaml` adds a switch between 443
-and 8443 every 20 s for a long run with clients attached. Each HTTPS connection takes about 26 KB of internal RAM

-
-`scripts/hx711`: classic ESP32, no wiring. SCK is GPIO32, DOUT GPIO33 (configured as an input with pull-up, so DOUT
-reads busy until the fake runs). `hxsim.hpp` starts from `on_boot` priority -100 (after the component has set up its
-pins), switches both pins to `GPIO_MODE_INPUT_OUTPUT` (it reads the clock and drives the DOUT level the component
-reads back) and runs a task pinned to core 0 (the ESPHome loop runs on core 1; core 0's idle task is removed from
-the task watchdog).
-
-- Ready means DOUT low; the task waits for the clock with interrupts off in 2 ms windows. Each rising edge puts the
-  next bit out and the 25th sets DOUT high; extra pulses pick the next conversion (25 A/128, 26 B/32, 27 A/64), and
-  each conversion takes 100 ms. Clock high for more than 60 us is power down (back to A/128), clock low powers up.
-- Values encode the conversion: A/128 is 128000+n, A/64 64000+n, B/32 -(32000+n), so a published value shows which
-  conversion it came from. `check.py CAP...` matches every `Got value` against the served values and exits non-zero
-  on an unmatched value, no values or a crash.
-- `mode`: 0 normal, 1 DOUT stuck high, 2 DOUT left low after the read.
-- The waiting and shifting code must run from IRAM. `IRAM_ATTR` on inline class members either gets inlined into
-  flash code or fails to link ("dangerous relocation: l32r: literal placed after use"); use static free functions
-  with `IRAM_ATTR __attribute__((noinline))` and check with `xtensa-esp32-elf-nm` that they sit at 0x4008xxxx. Run
-  from flash, the first transfer after boot lost one clock pulse (the value shifted right by one bit). Log from the
-  main loop (an interval drains an event ring), never inside the critical section.
-- Runs: `hxbase` (65 s), `hxpr1` channel B plus set_gain and power actions (115 s), `hxpr2`
-  power_down_after_reading (45 s). `hx-common.yaml` starts each run's `run_all` script and logs the `DONE` line.
-  `build.sh NAME TREE LABEL` writes `NAME<LABEL>.yaml` with its own name (so dev and the PR builds of the same config
-  do not share a build directory) and builds it; then `flashcap.sh DIR NAME<LABEL> TREE SECONDS` (`PORT`, `SC` in
-  the environment), which fails without a `DONE` line and runs `check.py`.
-- The configs have no Wi-Fi on purpose: the fake keeps core 0 busy with interrupts off in 2 ms windows, which would
-  starve the Wi-Fi task. Keep the harness without Wi-Fi, API or OTA.

-## Capture the wire, not the buffer (#21577)
-
-`templates/led_wire/wire.hpp` reads what the strips send, with no wiring:
-- RMT RX channels on the `esp32_rmt_led_strip` pads at 10 MHz, decoded with a high-time threshold per chipset
-  (ws2812 0.4/0.8 µs: threshold 7 ticks; sk6812 0.3/0.6 µs: threshold 4);
-- an SPI2 DMA slave fed from the `spi_led_strip` pads, with `spi: interface: spi3` for the strip.
-
-`led-wire-dut.yaml` (classic ESP32) drives a GRB ws2812 strip, a GRBW sk6812 strip, an SPI strip, an RGB light and a
-partition through steps S0 to S8 (on, `addressable_set`, lambda writes, partition, effect, power limit, off), logging
-the decoded `RMT`, `SPI` and buffer `GET` lines and `DONE` per step, then runs `stress_step()` over 300 shows and
-logs bad frames per strip. Diff the step lines of dev and the PR.
-
-- A comparison of the buffers alone missed a PR bug in which the start frame was not sent.
-- Give the captured strip `rmt_symbols` that hold a whole frame (192) and capture one RX channel at a time: with 64
-  symbols the TX refill interrupt stretches bits on dev and the PR alike while the capture runs. The substitutions
-  at the top of the config pick the strip.

-## rp2040_pio_led_strip: a self-sampling PIO probe (Pico 2 W)
-
-`scripts/pio_probe/pioscope.hpp` samples any GPIO from PIO2 at 25 MHz while another peripheral drives it (PIO reads
-the pad without taking the pin) and decodes WS2812-style pulses into bit timings and bytes; no wires or LEDs.
-`pa.yaml` probes five strips on PIO0 and PIO1 (WS2812 and two custom timings), `pc.yaml` one strip after claiming
-DMA channels 0 to 11. `run.sh pa|pc LABEL` builds, flashes, captures 40 s and prints the `RESULT` lines; a correct
-frame of two LEDs set to `Color(0xA5, 0x3C, 0x0F)` reads `3ca50f3ca50f`.
-
-- Turn the light on at full brightness before probing, or color correction writes zeros.
-- The probe FIFO overruns once in a while: count only full captures. `run.sh` fails unless every strip gave at least
-  one correct frame.
-- An RP2350 `panic()` escalates to a HardFault and the rp2 crash handler reboots within about a second, so a panic
-  during component setup boot-loops before USB CDC enumerates and the board looks dead (no port, no BOOTSEL drive).
-  Hold BOOTSEL while plugging it in and flash the UF2 drive. To see such a fault, trigger it after boot.

-## LibreTiny rtc preference emulation (#21007)
-
-The PR keeps `storage: rtc` preferences in FlashDB and deletes them on the first load or save after a boot
-whose `lt_get_reboot_reason()` is not software, watchdog, crash or sleep. Only the families listed in
-`_libretiny_rtc_supported()` accept the config keys; on others force the backend in with
-`platformio_options: build_flags: ["-DUSE_LIBRETINY_RTC_PREFERENCES"]` after confirming the rejection.
-
-- Harness: `scripts/libretiny_prefs/ltprefs.hpp` plus `templates/bk72xx-rtc-prefs-dut.yaml`. `ltprefs_boot()`
-  loads one rtc and one flash preference, a second pair that shares one key as rtc and as flash, and a third
-  rtc entry (so a hard reset drops three entries in one pass), logs the reason and both results, saves `100 + step`, syncs; after
-  a templated delay `ltprefs_exit()` bumps the flash-backed step and runs the step's action (`lt_reboot()`,
-  `__builtin_trap()`, `lt_reboot_wdt()` or idle). The last 8 boot reports are kept in a flash preference and
-  repeated in the 10 s alive line, so a boot missed by the capture (a power cut, an OTA-only board) is still
-  readable. Bump `run:` for fresh keys.
-- A store to an unmapped address does not fault on the ARM968, the board carries on: use `__builtin_trap()`
-  for the crash row. The SDK crash handler reboots about 10 s later. Works on BK7238 and BK7231N.
-- Hard resets: `serial_capture.py ... --reset` pulses RTS on CEN (reported as Power-On). A real power cut
-  needs a hand or a smart plug; the history in the alive line covers the boot the host cannot see. On the
-  Beken SDK a chip-enable reset and a power cut both report Power-On, there is no separate reset-pin source.
-- Step 0 and step 8 wait 30 s before acting so the host can open the port (and pulse a reset) after a flash
-  without losing the first boot; the flash tool's own reset starts the sequence immediately otherwise.
-- OTA-only board: keep the device's wifi, api and ota blocks verbatim, keep safe_mode, read logs with
-  `esphome logs <yaml> --device <name>.local` (the API attaches late, hence the history), and restore the
-  device's own config afterwards.
-- Plain-build comparison: `raw_firmware.bin` differs by the timestamp and by `__LINE__` in log calls of
-  functions below the added code; map offsets through `objdump -h` load addresses and `addr2line` before
-  calling a byte difference a code change.

-## BK72xx crash report on the next boot (#21012)
-
-Harness: `scripts/libretiny_crash/bkprobe.hpp` plus `templates/bk72xx-crash-probe-dut.yaml`. A flash
-preference holds the step; `on_boot` (priority -100) logs the reset reason, the SDK start type, two canaries
-and hex dumps of the low SRAM, a set of marker words and the record area after `.bss`, waits 30 s on step 0
-(so a capture can be opened after the flash) or 5 s, saves `step + 1`, syncs, then acts: 0 `__builtin_trap()`,
-1 call into unmapped memory, 2 unmapped and unaligned reads and a store (no fault on the ARM968), 3
-`lt_reboot()`. A `globals: restore_value` step counter does not work here: it is only saved from the global's
-loop, which a crash 50 ms later never reaches; save an `ESPPreferenceObject` and `global_preferences->sync()`
-first. Bump `run:` for fresh keys. Keep the `wifi:` block: the bug the fix addresses only shows with Wi-Fi up.
-
-Flow: `flash_bk72xx.py` (retry up to three times), one `serial_capture.py ... --reset` capture of 150 to 230 s,
-then `grep -a "libretiny.crash\|probe"`. Decode with
-`arm-none-eabi-addr2line -pfiaC -e .pioenvs/<name>/raw_firmware.elf <addr...>` (the ELF is `raw_firmware.elf`
-on LibreTiny), or run `scripts/libretiny_crash/decode_capture.py <yaml> <capture>` from the config directory
-to feed the capture through the CLI's `LogLineProcessor`.
-
-Expected: `*** CRASH DETECTED ON PREVIOUS BOOT ***`, `Reason: Undefined instruction`, PC on the `udf`,
-LR = PC + 1, BT0..BT7 walking the lambda, `StatelessLambdaAction`, `Action::play_complex`, `DelayAction`,
-`Scheduler::call`, `Application::loop`. The wild call reports where the core ended up (it executes zeros as
-Thumb NOPs until it wraps into real code), not the called address. Without the fix a dev build with Wi-Fi
-connected never comes back from the crash; see the BK72xx section in `boards.md`.
-
-OTA-only board: copy the device's own config, add the probe include and the step machine (step 0 crashes
-45 s after boot, later steps idle), keep its wifi, api, ota and safe_mode blocks and use the secrets file
-next to that config. A LibreTiny OTA is a 1.5 MB UF2 and takes minutes on a slow link, so do not wrap the
-upload in a short timeout. Read the replayed report with `esphome logs ... --device <name>.local` (an API

-## RTL8720C crash report on the next boot (#21648)
-
-`templates/rtl8720c-crash-buttons-dut.yaml` has one API button per case: `trap` (`__builtin_trap()`, usage fault),
-`bus fault` (store to 0x70000000, imprecise, CFSR 0x400), `wild call` (call to 0xFFFFFFF1, MemManage fault with PC
-0xFFFFFFF0 and LR in the caller), `isr trap` (a trap from a spare interrupt pended by software, hard fault), `hang`
-(interrupts off, the watchdog resets it and nothing must be reported) and `restart`. Every boot logs
-`boot reason N, crash record yes|no|n/a`; `n/a` means the handler is not built, as on a dev control build.
-
-Flow per build: flash with `flash_rtl87xx_kit.py`, start one `serial_capture.py PORT 600 OUT --released --ms`, then
-`scripts/libretiny_crash/rtl_drive.py HOST OUTDIR TREE YAML trap restart "bus fault" "wild call" "isr trap" hang restart`.
-The `restart` after the first crash checks the report shows only once. Time each reset from the serial capture
-(the ROM fault dump to the next `ROM Version` line), not from the API port: the board is back before an API client
-notices it went away. Compare the reported PC with the `PC  =` line of the ROM dump, and check the decoded lines in the
-`caseN-*.txt` files. Pass the UF2 by name (`firmware.uf2`): the build directory holds a second identically sized copy.
-
-Regression rerun of the same flow (#21728): `scripts/libretiny_crash/rtl_rom_vs_report.py CAPTURE` lists, for each ROM
-fault dump in a `--ms` capture, the ROM's CFSR and PC, the ms to the next `ROM Version` banner and the Reason, CFSR, PC
-and SP the next boot reported, so two builds compare line by line. The ROM lines start with a bare CR; split the
-capture on newlines only. The imprecise bus fault's PC moves between builds (it is wherever the core was when the
-fault was raised); compare it with that run's ROM dump, not with another build. SP stays the same per fault (8 word
-frame, no FPU). On the BK7238 time the reboot from the button press to the next `BK7238_1.0.14` banner (0.6 to 0.7 s).

-## BK7238 BLE and flash sector safety (#21735)
-
-The Beken BLE bond store reads its partition at boot and erases that sector when the CRC does not match; before
-LibreTiny 1.14 the partition was unmapped and pointed at sector 0, erasing the bootloader (#18646). To prove a change
-like this safe on a board that cannot be recovered without a dump:
-
-1. Take a full backup first: `scripts/bk72xx_flash/readback.sh full-before` (ltchiptool family `beken-7238`, about
-   190 s for 2 MB). Keep it until the board is back on a known build.
-2. Serial flash a build without the feature, then deliver the feature build by OTA (the path users take). Use
-   `bk72xx: framework: sdk_silent: none` with `logger: hardware_uart: UART1`, so the SDK's own lines (bootloader
-   banner, `CRC fail, remove bonded info`) show up in the capture.
-3. Soak with Wi-Fi up, OTA again from the new build, pulse CEN a few times (`serial_capture.py --reset`), and check
-   each boot comes back through the bootloader.
-4. Read the whole chip again and run `scripts/bk72xx_flash/partdiff.py full-before.bin full-after.bin
-   <libretiny>/boards/_base/beken-72xx.json`: bootloader, calibration and userdata must be unchanged; app, download
-   and one KVS sector change normally.
-
-Check what already sits in the target partition before the first boot: on an XH-WB3S that shipped with Tuya firmware,
-0x1E1000 (the `ble_bonding` partition of the generic Beken layout) held the Tuya `diff2ya` record (magic `ba dc cd
-ab`), which the bond store erased on its first boot. Nothing depended on it there, but say so in the results.
-
-## BK7238 OTA and the board layout (issue #18222)
-
-A BK7238 has one of two bootloaders, and the board in the YAML must match it: Beken OEM (`BK7238_1.0.14` in the
-boot banner, `generic-bk7238`, OTA as RBL to `download` at 0x132000) or Tuya T1 2.0.0 (`generic-bk7238-tuya`,
-`t1-*`, `download` at 0x12C000 plus a `diff2ya` record at 0x1E1000). `ltchiptool uf2 info` on `firmware.uf2` shows
-the layout an image targets (`FAL_PTABLE`, `OTA_PART_INFO`). Measured on the OEM bootloader (2026-10-27):
-
-| Running | Uploaded | Result |
-|---|---|---|
-| Tuya layout | Tuya layout | upload succeeds, bootloader prints `App verify failed! Need to recovery factory firmware.`, old build stays |
-| Tuya layout | OEM layout | applied |
-| OEM layout | Tuya layout | `End error: 9` (`UPDATE_ERROR_ACTIVATE`: no `RBL` at the running download offset), old build stays |
-| OEM layout | OEM layout | applied |
-
-Run it with a full backup first (`scripts/bk72xx_flash/readback.sh`), `sdk_silent: none` so the bootloader's lines
-show, and each result checked against `build_info.json` over the API. A Tuya-layout build on an OEM-layout module
-reads the RF calibration from 0x1E3000: copy the 0x1E0000 sector there for the test and erase it afterwards. The
-Tuya OTA writes up to about 0x1EF000 and its own settings at 0x1E4000, so write those sectors back from the backup
-and check with `partdiff.py`.
-
-## RTL8710B Wi-Fi join diagnosis (issue #21742)
-
-For a board that joins rarely: build `dev` with `sdk_silent: none`, log `wifi_get_last_error()` and
-`rtw_join_status` after each failed `WiFi.begin()`, and dump the efuse map once (see the AmebaZ section in
-`boards.md`). The driver log tells the stages apart: `start auth to` with nothing after it is the AP not answering,
-`auth success, start assoc` then `association success` then error 3 is a failed 4-way handshake, and
-`sta recv deauth reason code(6)` is the AP dropping the session mid-handshake. Tally per BSSID: if the share of
-auth frames answered falls with distance while receive stays strong, the board's transmit path is weak.
-
-A/B a value one boot at a time so time of day and AP state hit both sides equally. Keep the trial counter in a
-`restore_value` global, set the value in an `on_boot` lambda at priority 600 (before Wi-Fi starts), and reboot
-after a fixed window:
-
-```yaml
-esphome:
-  on_boot:
-    priority: 600
-    then:
-      - lambda: |-
-          // value under test, read by the code being measured
-          wifi::diag_value = (id(trial_idx) % 2) ? 0x3A : 0;
-          ESP_LOGW("trial", "TRIAL %d start value=0x%02X", id(trial_idx), wifi::diag_value);
-      - delay: 75s
-      - lambda: |-
-          bool ok = wifi::global_wifi_component->is_connected();
-          ESP_LOGW("trial", "TRIAL %d value=0x%02X result=%s", id(trial_idx), wifi::diag_value,
-                   ok ? "JOINED" : "FAILED");
-          id(trial_idx)++;
-          App.safe_reboot();
-```
-
-Turn off `api:` and `wifi:` `reboot_timeout`, and leave out `ap:` unless the AP is the variable under test.
-Do not cycle trials with `wifi.disable` and `wifi.enable`: doing that while connected reset the RTL8710B on the next
-scan. Results from 2026-10-27, on one BW12 with blank efuse calibration: crystal trim `0x20`, `0x30` and `0x38`
-all joined 20 of 20 trials, and boosted TX power indexes changed nothing against an AP that answered 0 of 43
-auth frames.
-
-Known LibreTiny behaviour seen here: after a join with a BSSID and channel, LibreTiny's partial-scan reset leaves
-the next SSID-only join with nothing to scan (`RTW_NONE_NETWORK` in about 18 ms). That is a firmware bug, not
-the board; passing channel 0 avoids it.

-Set `static_ip` to the board's own DHCP lease so nothing collides, and DNS2 to a server DHCP does not hand out
-(9.9.9.9), so the dump and `dns_getserver()` prove the manual values are in use. A missing SSID with its own

-## PPPoS modem component with no modem attached (#6721)

-A boot check on a classic ESP32 devkit with the modem UART pins left open. `templates/modem/modem-common.yaml` is

-WebSocket, so it subscribes on the plain listener of the same broker. Cases: `tcp` on 1883, `ws` on 9001, `wss` on

-## MAC suffix topics (#9315)

-`scripts/mqtt/mac_suffix/run.sh X BUILD` compiles (from `TREE`) and flashes variant X (a defaults, b custom `topic_prefix`, c explicit topics,
-d no suffix) of BUILD (`pr` or `base`) on an ESP32 and a D1 mini, records the broker with
-`mosquitto_sub -F '@H:@M:@S r=%r %t %p'`, presses Restart through the `cmd_t` found in the discovery payloads, then
-holds both chips in the bootloader for 40 s (`esptool --after no-reset chip-id`) so the broker sends the will; a
-plain reset only gives "session taken over" and no will. The two boards' configs live in separate folders because
-variants a to c share a `name` (the MAC suffix tells them apart), and the same name in one folder shares a build
-directory. A D1 mini CH340 can garble the serial capture after an RTS reset, so read its topics from the broker.
-`esphome logs --device MQTT` on a current tree needs paho-mqtt 2.x; an older venv with 1.6.1 fails, so use a venv
-made from the tree's requirements.txt. A Restart press never delivered the shutdown message on any build tested.

-## Shutdown message delivery (#21566)

-`scripts/mqtt/shutdown/`: `sd-common.yaml` sets birth/will/shutdown payloads `hello`/`dead`/`bye` so the shutdown
-message and the will cannot be confused, and takes `restart`, `disable` and `sleep` on `<name>/cmd`.
-`sdrun.sh V N` (`TREE`, `P32` and `P66` in the environment) compiles and flashes the ESP32 and D1 mini, restarts each N times, disables MQTT once and deep sleeps the ESP32 three
-times (never the D1 mini: without the GPIO16 to RST wire it never wakes); `match.py OUT` counts a `bye` within 5 s of
-each command. Dev: ESP32 0/10 restarts, D1 mini 1 to 3/10. Put the broker address (`broker_ip`) in the secrets.yaml next to
-the included package, and quote `"${name}/status"` inside flow mappings.

-boards and 3/3 deep sleeps, against 1/10, 3/10 and 0/3 on base. An earlier 100 ms hold gave 3/10, 6/10 and 2/3, so

-## MQTT discovery against a throwaway Home Assistant (#21956)
-
-Run a Home Assistant dev install with its own config directory (`hass -c <scratch>/ha`) holding `http:
-server_port: 8129`, `api:`, `config:`, `onboarding:` and MQTT debug logging, plus a local mosquitto on 1883. In
-`scripts/mqtt/ha_discovery/`, `onboard.py DIR` creates a generated test user (the credentials stay in DIR) and a
-token, `flow.py TOKENFILE` adds the MQTT entry (the `protocol` and `other_settings: {set_client_cert: false,
-set_ca_cert: "off", transport: tcp}` fields are required), and `hadrive.py TOKENFILE NAME` reads the device's time,
-date and datetime entities, calls `set_value` on each and reads again; it exits 1 on a missing entity, a failed
-call or a state that does not read back the value that was set. The three share the REST calls in `ha_rest.py`. `dt-common.yaml` is the device side (classic ESP32, three
-template datetime entities, `${broker}`).
-
-- The HA dev branch keeps a YAML port change as a pending HTTP config and reverts it after 5 minutes. Before
-  starting HA again, set `data.stable.server_port` to 8129 and `data.pending` to null in `.storage/http`.
-- ESPHome MQTT unique ids are name based: clear the previous build's retained discovery (`mosquitto_pub -r -n` on
-  each config topic) and expect the entity ids of the first build.

-## mqtt.disable and broker drops on ESP-IDF (#22230)
-
-`scripts/mqtt/disable/disable-common.yaml` disables MQTT for 30 s every 60 s (every third cycle starts with fast
-toggles, a disable while connecting), publishes a tick every 2 s and logs `EV CONNECT`, `EV DISCONNECT` and
-`EV MSG`. `run.sh LABEL outage|drop SECONDS` (env `TREE`, `PORT`, `SC`, `PY`, `BROKER`, `BROKER_PORT`) starts a
-private mosquitto so it can stop and start it, flashes and captures:
-- `outage` publishes to `md<LABEL>/in` every second and stops the broker inside a disabled window; `analyze.py`
-  prints per window the device connects, inbound messages, broker connects, ticks that reached the broker and the
-  time from enable to connect, and fails the run on a device connect or an inbound message inside a window.
-- `drop` stops the broker 6 s after every enable for 15 s. This is the case that found a watchdog reset: calling
-  `esp_mqtt_client_stop()` while the esp-mqtt task sleeps in WAIT_RECONNECT blocks the caller for up to
-  reconnect_timeout/2 (5 s), 6 of 6 task watchdog resets on an S3 and a C6.
-
-Both modes also fail when the device never connects or the broker was never stopped, and `outage` when no inbound
-message arrived.
-
-Use the host's current address for `BROKER`: a stale one gives `esp-tls select() timeout`. Before #22230 the client
-reconnects on its own during disable (14 of 16 windows). Results:
-https://github.com/esphome/esphome/pull/22230#issuecomment-6614854671
-
-## Retained message burst at connect (#22200)
-
-`scripts/mqtt/retained_burst/`: `burst-topics.yaml` (a package) subscribes 25 `on_message` topics plus 15 switch
-command topics, `burst-common.yaml` logs the counts 15 s after the connect, and `seed.sh BROKER_PORT` leaves all 40 retained on a local mosquitto (`seed.sh BROKER_PORT clear` removes them).
-`run.sh LABEL BOOTS` (env `TREE`, `PORT`, `SC`, `PY`, `BROKER`, `BROKER_PORT`, default board an ESP32-C3) resets the
-board BOOTS times and prints `RESULT got=x/25 switches_on=y/15` and any `Dropped` lines per boot; it passes only with
-40 of 40 on every boot. Before #22200 the C3 dropped exactly 49 events (80 events minus 31 slots): the main loop
-drains nothing during the burst.
-
-## Forced reconnect mid-burst (#22248)
-
-`scripts/mqtt/reconnect/`: `kick-common.yaml` includes the same `burst-topics.yaml` and counts per connection with
-a `mode: restart` script on `on_connect`, logging `RESULT` 6 s after each connect. It and `run.sh` use files from
-`../retained_burst/`, so copy the whole `mqtt/` directory to the scratch directory. `kick.py BROKER_LOG BROKER_PORT
-PREFIX CYCLES` tails the broker log and takes over the device's client id 0 to 400 ms after every other connect
-(mosquitto drops it with "session taken over"), then leaves the next connection alone for 8 s and ends it. It
-starts by kicking the connection that is already up and skips its own connections (from 127.0.0.1 with the same id).
-`run.sh LABEL CYCLES` (env as above plus `BROKER_LOG`) seeds, flashes, waits for the first connect and runs the
-kicker. The device counts its first connection as CONN 1, so the kicked ones are the even CONN numbers and the
-left-alone ones the odd numbers from 3 up; kick.py prints each left-alone connection with its time and CONN number,
-and `judge.py` pairs those with the RESULT lines by time and passes when every one has `got=25/25`. A reset after
-the first connect fails the run. Retained switch commands fire `on_turn_on` only on the first connection, so
-`switches_on` is not judged.

-`zephyr/scripts/build/uf2conv.py -f 0xADA52840 -c` and copy the .uf2 to the volume (the copy ends in an I/O error

-## zephyr_ble_server connection slot under reordered callbacks (#21723)
-
-`scripts/zephyr_ble_server`: the ItsyBitsy runs `server.yaml` (one connection slot) and an ESP32 runs `client.yaml`,
-which connects, drops the link 300 ms later and reconnects as soon as the server advertises again. `run.sh NAME 90`
-flashes the UF2, counts the server's `Connected`/`Disconnected`/`Advertising` lines and the client's connects,
-and ends with PASS (more than one server connection) or FAIL; an empty capture or a silent client fails the setup.
-
-- The connect and disconnect callbacks each `defer()` to the main loop and the bug needs the disconnect handled
-  first, which cannot be forced over the air. Force it with a test-only patch on both trees: replace the connect
-  callback's `defer(...)` with `set_timeout(5000, ...)`. A leaked reference then shows as one connection and nothing
-  after it (the dump still lists the closed link); a fixed build keeps cycling (17 in 90 s on #21723).
-- `dfu: true` makes the next flash a 1200 baud touch; an app built without it needs a double tap on RESET. The
-  Zephyr app enumerates as `2fe3:0100`, the bootloader as `239a:0051`, so find the board by its USB serial number.
-- macOS is a poor central here: it keeps old bonds with a board (`Peer removed pairing information` on connect)
-  and clearing them is a system setting. Use an ESP32 `ble_client`; the server's random static address comes from
-  its own log.

-## SMP over UDP OTA over Thread, with reset faults (#17245, #21910)
-
-Setup: a Thread border router (see openthread.md) whose OMR prefix the laptop routes to, and an ItsyBitsy nRF52840
-(the Adafruit bootloader carries the MCUboot layout; the nRF52840 Dongle's Open DFU bootloader is rejected for
-`zephyr_mcumgr` OTA). `scripts/smp_udp_ota/smp-udp-ota-dut.yaml` joins the network with `force_dataset: true` and
-logs its build label every 10 s. The first image goes in over UF2, every later one with
-`ota.sh MODE YAML VER ADDR` to the device's OMR address. A full image (about 380 KB) takes about 130 s.
-
-- An ESP Thread Border Router board running ESPHome `openthread: border_router: rcp:` works as the border router
-  (pins in `boards.md`). Give both it and the device a fixed dataset with `force_dataset: true`; each keeps an old
-  stored dataset otherwise. The host learns the route to the OMR /64 from the border router's RA; ping the
-  device's OMR address before the first upload.
-- Install the smpclient version pinned in requirements. An older one fails with `unexpected keyword argument
-  'timeout_s'` and a missing `get_max_cbor_and_data_size`, which looks like a PR bug. Check the version with the
-  Python of the venv that runs ESPHome, not a system pip.
-- The build holds two `zephyr.uf2` files. Copy `.pioenvs/<name>/zephyr/zephyr.uf2` (the app, from 0x26000 up,
-  about 827 KB). `mcuboot/zephyr/zephyr.uf2` (about 70 KB) lands on the app slot and the board stops enumerating;
-  double tap RESET and copy the right one.
-- To log the device's addresses, format `otIp6GetUnicastAddresses()` by hand: `network::IPAddress::str_to()`
-  does not link on nRF52 (no `inet_ntop`).
-- A new image refuses the next upload (`No free slot. Testing mode but not confirmed yet.`) until it confirms itself.
-  Wait about 4 minutes between uploads.
-- An image that is already in the secondary slot is only marked and reset (a few seconds). Change `ver` for every
-  upload that has to transfer, and expect a host-only change to rebuild byte-identical firmware.
-- `inject.py` faults the reset on the host: `lostreply` drops the reply of a reset the device got, `lostreq` drops the
-  first request, `lostreq2` drops every reset. The device resets after a short delay, so even after a lost reply the
-  client usually still finds the old image running with the new one pending and resends the reset to the old image,
-  which is safe. `lostreq2` must end in an error with the old image still running. `ota.sh` ends with `check.sh`,
-  which prints PASS or FAIL for the mode, and `inject.py` fails the run when no reset was faulted.
-- Without `libc_nano` the config overflows the 396,800 B slot by about 4 KB with Zephyr's TCP stack linked (about
-  11 KB of it, unused by SMP over UDP). With TCP left out (#21910) it fits with the full libc. A config with `api:`
-  keeps TCP.
-- **The real OTA size limit is lower than the link limit.** The nRF Connect SDK partition manager overrides the device
-  tree, so read `partitions.yml` in the build directory, not `zephyr.dts`. On the ItsyBitsy layout `mcuboot_primary` is
-  0x61000 (97 sectors of 4 KB, 0x2f000 to 0x90000) and the app partition 0x60e00 (396,800 B); `mcuboot_secondary`
-  is 0x90000 to 0xf1000 and `settings_storage` 0xf2000 to 0xf4000. MCUboot swap using move keeps one sector for
-  its trailer and one for the move, so it only swaps in an image up to (97 - 1 - 1) × 4 KB = 389,120 B
-  (`app_max_sectors()` and `app_max_size()` in bootutil `swap_move.c`). An image between 389,120 and 396,800 B links,
-  uploads and the CLI reports `Successfully uploaded program`, but MCUboot never swaps it in: it stays pending in the
-  secondary slot, and every later upload and the SMP image erase fail with `NO_FREE_SLOT`. OTA stays stuck until
-  the slot is cleared over USB. Measured: 388,787 B swapped in, 392,155 B did not. `ota.sh` checks `app_update.bin`
-  against this limit with `mcuboot_slot.py limit` before it uploads, and afterwards asks the device which image runs
-  (`mcuboot_slot.py active`, by the image's SHA-256), since the CLI's exit code alone is not proof. That check passes once the
-  new image runs and says whether it has confirmed itself; add `--expect confirmed --wait 300` to prove it stays.
-- With #17245 at 03d45d1aaa the build itself fails above the limit (`The application image is N bytes, but MCUboot
-  can only swap in L bytes on this board`), and after a confirmed reset the client waits for the device and logs
-  `runs the new image` or fails with `rebooted but did not swap in the new image`. After a dropped reset reply it still
-  ends with `The reboot of ... is not confirmed` without that wait, so `ota.sh`'s own image check is what proves those
-  runs.
-- Clearing a stuck pending image: the SMP image erase is refused while the image is pending, and resets do not help.
-  Over USB, touch the app's CDC port at 1200 baud to enter the UF2 bootloader, then copy the 16-block UF2 from
-  `mcuboot_slot.py blank-uf2 BUILD OUT`, which writes 0xFF over the secondary slot's header page (`mcuboot_secondary`
-  in `partitions.yml`, 0x90000 on the ItsyBitsy). The bootloader resets on its own once the last block is written
-  (`cp` may report an I/O error then, which is normal), MCUboot finds no image header and clears the slot, and the
-  image states show slot 0 only.
-- Over USB, the Adafruit UF2 bootloader only accepts blocks inside its app area (its `CURRENT.UF2` maps 0x1000 to
-  0xE9000). A UF2 with a block outside that area is never completed, and the bootloader then ignores every
-  later file, even a good app UF2, until a physical reset (double tap RESET or replug). Keep hand-made UF2 writes inside the app area.

-real multi-row PNG), a flat 640x480 PNG (1.6 KB for 307200 pixels), 231 KB of noise and a JPEG. The device is

-ESP32 without PSRAM) and `debug` loop time and heap sensors at 2 s; the 256 byte buffer image stays RGB565, so do
-not point big images at it (out of memory on every build). `scripts/online_image/pngdrive.py HOST KEY LOGFILE
-BASEURL LABEL` (default case set `png`; `CASES=short` for the six case list) calls the actions, waits for the
-finished or error line and reports the case time, the highest loop time and the lowest free heap. The per pass `online_image.image took a long time` values come from
-the serial capture and only print on a new maximum, so read the first fetch of each image. The pass that decodes a
-whole buffer is the decoder cost (before the change 510 ms gradient and 1980 ms flat, after it 77 and 140 ms); for
-the noisy PNG the longest pass is the blocking 64 KB read on both builds (0.7 to 3.7 s). Alternate PR, base, PR
-for a timing claim.
-
-For a replacement PR, compare against the parent PR head, not dev. `CASES=noise` fetches the noisy PNG three times
-(run it right after a boot, alternating builds); `CASES=end` runs flat and gradient as plain, `noclen_`, `chunked_`,
-`half_` and `stall_` through the prefixed server cases below.
-
-## JPEG decoded as it downloads (#21342)
-
-`oi_server.py` serves prefixed cases on any file: `half_<file>` (first half, matching Content-Length),
-`noclen_<file>` (close delimited), `chunked_<file>` (1 KB chunks), `stall_<file>` (a third, then the socket held
-40 s). `scripts/online_image/make_jpegs.py <www>` writes noise, gradient, 12 KB EXIF and progressive JPEGs. Device:
-`templates/online-image-dut.yaml` with `type: BINARY` on both entities and `buffer_size: 4096` on the second;
-`CASES=jpeg scripts/online_image/pngdrive.py HOST KEY LOGFILE BASEURL LABEL` runs the JPEG list; every case set
-prints case time, highest loop time and lowest free heap. Before the change a JPEG needs a contiguous block of its file size (233 KB never
-allocates on a classic ESP32, and after a few failures 69 KB does not either until a reboot); after it the 64 KB
-buffer stays 64 KB and 4 KB is enough for a baseline JPEG. The first pass still reads up to `buffer_size` in one
-blocking read, so the 64 KB entity blocks 1.7 to 4 s and the 4 KB one 272 ms at most; judge the decode budget on
-the small buffer entity. Already on dev: a JPEG without Content-Length (plain or chunked) ends with `Could not open
-image for decoding: 4` then `Invalid type`.

-## BMP and QOI decode time limit (#21392)
-
-Use a wired board (`templates/online-image-s3-eth-dut.yaml`: Waveshare ESP32-S3-ETH, W5500, PSRAM, `type: RGB565`)
-rather than a classic ESP32 on Wi-Fi: with a weak link the reads block up to the 4.5 s timeout and the per case loop
-numbers are noise. `scripts/online_image/make_bmp_qoi.py <www>` writes 1 bit BMP 640x480, 8 and 24 bit BMP 320x240,
-QOI 640x480 one colour (all runs) and checkerboard, QOI 320x240 gradient and noise. `pngdrive.py` with
-`CASES=bmpqoi` runs each as plain, `noclen_`, `chunked_`, `half_` plus stalls. The `loop_time` sensor sits at 75
-to 160 ms even for a 16x16 image, so for decode passes use `scripts/online_image/firstpass.py HOST KEY BASEURL
-LABEL IMAGE...`: it reboots the device before each fetch and reports that fetch's `took a long time` maximum. A
-`half_` file with matching Content-Length reports `download finished` with "not caching it" on dev too.

-
-`scripts/sim_buses/` and `scripts/static_buffer/`. Each header is added with `esphome: includes:` and wired in an
-`on_boot` lambda, so no chip is needed. The wrappers take the real bus or SPI delegate and pass through every
-address they do not simulate.
-
-- `lcdsim.hpp`: `LcdSimBus`, an `i2c::I2CBus` wrapper that plays PCF8574 backpacks (P0 RS, P2 EN, P4 to P7 D4 to D7)
-  driving HD44780 controllers. It decodes the EN-strobed nibbles and rebuilds the rows written after each 0x80 and
-  0xC0 address command. `add()` up to three addresses, hand it to each `lcd_pcf8574` with `set_i2c_bus()` at
-  `on_boot` priority 800, and call `report()` from an interval. `lcd_an.py SERIAL` checks the rows against the
-  patterns its docstring lists (0x27 20x4, 0x26 16x2, 0x25 64x4), and fails on a display whose frame count does not
-  grow between its first and last report, on a segment longer than its rows or on
-  data past the 128 byte segment buffer, which the report counts as `overflow`, on a report from an address it does
-  not expect, or on any read (`reads`; the driver never reads, so the simulator NACKs them). A 64x4 display hangs the
-  code before #22331 in
-  setup.
-- HT16K33: use `templates/i2c_fake/htfake.hpp` with its test runner (see [fake_i2c.md](fake_i2c.md)).
-- `mxsim.hpp`: `MxSniff`, an `spi::SPIDelegate` in front of the real one that keeps what each MAX7219 in a chain
-  latches. Swap it in at `on_boot` priority 399 through `DelegatePeek::of(id(x))`:
-  `auto &d = DelegatePeek::of(id(x)); d = new MxSniff(d, chips);`. `mx_an.py SERIAL CHAIN...`
-  summarizes the reports, CHAIN being each name passed to `report()`, and fails on a named chain with no report line,
-  on malformed transactions (byte count not two per chip, or a partial byte from `write()` or
-  `write_cmd_addr_data()`, which are recorded and forwarded too), on a named chain with fewer than two report lines,
-  or a chain whose transaction count stays 0 or stops growing, and prints PASS otherwise.
-- `spysim.hpp`: the same delegate trick (both headers carry `DelegatePeek`, so one config can include both), logging length and FNV-1a hash of every transaction over 1000 bytes (whole
-  frames, used for `pixoo`). `write()` and `write_cmd_addr_data()` are hashed and forwarded like `write_array()`;
-  a partial byte or a bus width other than 1 is hashed as whole bytes, so the SPY line carries `odd`, the count of
-  such transactions, and a dev vs PR hash match only holds when `odd` is 0 on both.
-- `pisim.hpp`: drives two `packet_interface` stacks on cross-wired UARTs through `top()`, with payloads whose bytes
-  are a function of their index so every byte is checked, and the index and length each side sent (last 256) so a
-  truncated or split packet, or one whose slot a later index reused, counts as `rx_bad`. Send indices 0, 1, 2 and so
-  on from each side: a skipped index counts as `rx_lost` and an old or repeated one as `rx_bad`. `report(tag, true)` once both links are idle ends each
-  line in PASS only when that side received every packet the peer sent intact and the peer had no send refused;
-  `missing` is the rest, packets still in flight or lost at the tail. `packet_transport` drops packets carrying its own device
-  name, so a one-board test must use the layers directly.
-- `hcsim.hpp`: a software SN74HC165 chain on ESP-IDF (data GPIO6, clock GPIO7, load GPIO10). A falling load edge
-  latches the pattern and each rising clock edge drives the next bit onto the data pad, which is in
-  `GPIO_MODE_INPUT_OUTPUT` so the component reads it from the same pin. Call `hcsim::report(label, loads0, clocks0)`
-  after each window with `hcsim::loads` and `hcsim::clocks` from its start; it logs `INVALID` instead of a result
-  when the GPIO or interrupt setup failed or the window saw no load or no clock edge, so a dead simulator cannot pass
-  as a wrong but steady pattern.
-- `ledprobe.hpp`: samples a status LED (or any output) pin every 2 ms from an `esp_timer`, off the loop task, and
-  prints blink count, on time, period and the longest gap per window. It measures `status_led` while the loop is
-  blocked (#16407). Pass `ledprobe::n` from the window start as the mark; a window with more than 400 edges logs
-  `INVALID` and no result line instead of passing for a stalled LED. So does every window when the pin or timer
-  setup failed or the timer has not sampled for 100 ms, so a dead probe cannot read as a quiet LED.
-- `fakeha.py HOST OUT_PREFIX`: an aioesphomeapi client standing in for Home Assistant for `homeassistant` select
-  mirrors. It answers state subscriptions from a table, pushes option and state changes (full, overfull, quoted,
-  unparseable), checks each step through a "Dump" button, captures the action calls, churns 600 option updates
-  while watching the heap, and checks the entity options after a reconnect. A step fails when either DUMP line is
-  missing, and a rejected update also needs the device's rejection log line, so an update that never arrived cannot
-  pass. Exits 1 on a failed step and prints PASS otherwise.
-- `wizard_drive.py HOST`: finishes the device wizard through aioesphomeapi 46.28 (`device_wizard`,
-  `wizard_input_set`), answers the subscriptions the inputs create and checks the values reached the entities.
-
-## Static buffers (`cg.static_buffer`)
-
-`scripts/static_buffer/` holds two local external components and `static-buffer-dut.yaml`, which loads them:
-- `sbtest` allocates three buffers with `cg.static_buffer` (37 `uint8_t`, 5 `uint32_t`, and `const char *` sized by
-  a C++ expression) and checks at setup that they are zeroed and aligned, then fills each completely; at
-  `dump_config()` it checks no other instance's fill reached them. Two instances prove the buffers are distinct.
-  Both `SBTEST` lines end in `PASS` or `FAIL`; the `dump_config()` one passes only when the setup checks passed too.
-- `sbpsram` asks for `psram=True` and uses the pointer codegen hands it: the static buffer without PSRAM, or a
-  zeroed `psram_buffer<T>()` with a `psram:` block, which logs `external=1` (nullptr if the allocation failed).
-  It also gets a plain 8 word `uint32_t` static buffer, which must be non-null, aligned and zeroed at start and read
-  back its fill (`plain=1`). Its `dump_config()` line ends in `PASS` only when both readbacks match, both buffers
-  were zeroed at start and, with PSRAM, the PSRAM one is in external RAM.
-
-## Gotchas
-
-- Some "classic" devkits with a CP2102N carry an ESP32-PICO-D4. GPIO16 and GPIO17 are its flash pins, and an
-  ESP-IDF build that drives them hits the interrupt watchdog. Use `board: pico32` and GPIO9/GPIO10.
-- An `addressable_light` display writes nothing until its light is turned on.
-- Before calling a rebased PR's change trivial, diff the PR's own diff (head against its parent) old against new: a
-  move that looks like a merge only can carry real commits from below.

-## Media player pipeline tasks (#21203)
-
-The `speaker` media player platform (`speaker/media_player/`) creates `ann_read`, `ann_decode`, `med_read` and
-`med_decode` FreeRTOS tasks on every play and deletes them after a stop. The AUX-2 and sendspin packages use the
-`speaker_source` player instead, which has its own pipeline and never runs that code, so a test of
-`speaker/media_player/*` has to swap the player: `templates/aux-2-preprod-speaker-player-dut.yaml` removes the
-package's `external_media_player` with `id: !remove` and adds a `speaker` platform player on the package's resampler
-speakers, plus a "Task names" button whose lambda calls `xTaskGetHandle()` on the four names and logs internal free
-heap. Serve FLAC files from the host (`ffmpeg -f lavfi -i "sine=frequency=440:duration=90" -ac 2 -ar 48000 -c:a flac
-media90.flac`, a 3 s mono one for announcements, `python3 -m http.server 8765 --directory www`); `audio_http`
-refuses WAV and MP3. `scripts/speaker_media_player/cases.sh HOST KEY MEDIA_URL ANN_URL CAPTURE LABEL` runs three
-cycles through `drive.py` (`play:URL | ann:URL | stop | press:NAME | wait:S` on one API connection) with the probe
-pressed idle, during media, during the announcement, after it and after the stop. Pass: idle none, media `med_*`
-only, announcement all four, after stop none, every cycle. API commands land a second or two late over Wi-Fi, so read
-the probe against the `State changed to` lines rather than the driver's timestamps. Internal free heap after a stop
-moved by 2.5 kB between two boots of the same build, so a heap delta needs more than one boot per build. Results:

-## Streamed TTS with a pause (#21090, #21091)
-
-Home Assistant streams TTS while it is still being generated, so the player must start on the first part instead of
-waiting for the whole file. `scripts/speaker_tts_pause/`:
-- `mk.py INTRO_AUDIO CONT_AUDIO www/s1.flac` builds one 48 kHz mono FLAC stream (the intro padded to a 4096-sample
-  frame boundary, then the continuation) and writes the byte offset of the split to `s1.flac.cut`. Make the intro
-  with any TTS, e.g. `say -o intro.aiff "..."` on macOS; build a short one (`s1`) and a long one (`s2`).
-- `srv.py PORT www` serves the file chunked: the header and intro at once, then it holds the connection open for
-  `PAUSE` seconds (8), then the rest.
-- `tts-common.yaml` swaps the AUX-2's `speaker_source` player for the `speaker` platform player and counts played
-  frames with `add_audio_output_callback` on both resampler speakers into the counters in `frames.h` (one `[frames`
-  log line per change, read over serial with `--ms`). Its `on_boot` must be a list entry: a dict `on_boot` replaces
-  the package's list and the AUX-2 never starts Wi-Fi or Ethernet.
-- `run.sh LABEL=TREE...` flashes each build and drives two short-intro and two long-intro announcements and one
-  media play through `scripts/speaker_media_player/drive.py` (set `DRIVE` when running from a scratch copy); `an.py`
-  prints first audio, the server's send times and how much of the intro played before the rest arrived, per request.
-  A request fails when it never played the whole intro or stopped short of 95 % of the stream.
-
-Before the two PRs the player waited for the rest of the stream (8.2 s) for both a 22.5 KB and a 50 KB intro; with
-both it starts at about 1 s.

-## Voice PE wake word audio (#21885)
-
-`scripts/voice_wake_word_audio/va.py HOST KEY OUTDIR accept,reject,timeout` stands in for Home Assistant
-(aioesphomeapi 46.27.0 or later, `wake_word_audio=True`), answers each run by mode and saves both channels as WAV;
-`locate.py OUTDIR` finds the played phrase in them by envelope cross-correlation against `wake16k.wav`.
-`run.sh HOST TAG [ROUNDS]` runs reject and timeout rounds while playing the phrase every 9 s, starting once `va.py`
-is READY. `va.py` fails a START before READY or during a run, and `run.sh`, `stale.py` and `mww.py` fail at once
-when the player fails or hangs for 30 s.
-
-- Give the test build its own API key so Home Assistant cannot hold the voice assistant subscription.
-- Make the phrase with any TTS (`say -o wake.aiff "Okay Nabu"`, then `ffmpeg -i wake.aiff -ac 1 -ar 16000
-  wake16k.wav`) and play it from the host near the device (`PLAY`, default `afplay`). On macOS the terminal needs
-  audio permission first; before that `afplay` hangs.
-- The PE mute switch only mutes samples. To stop microWakeWord, add `mww-buttons.yaml` (template buttons calling
-  `micro_wake_word.stop` and `start`); `mww.py` checks that no run starts while it is stopped.
-- Stale clip check: `stale.py` says a spoken marker word (`marker.aiff`), stops microWakeWord for 3 s, starts it and
-  says the wake word; `stalean.py` measures loud audio before the phrase in each clip and exits 1 above
-  `MAX_LOUD_MS` (default 100). The loud level has no default: calibrate `LOUD_LEVEL` on each setup from the phrase
-  and pre-phrase peaks it prints (a run without it prints them and fails), somewhere between room noise and the
-  marker's peak. A trial whose phrase peak is under twice `LOUD_LEVEL` fails as too quiet to judge. A steady 1 kHz
-  beep never reaches the PE stream (the XMOS processing removes it), so the marker has to be speech.

-
-- Push-style sensors: put the component on a UART, switch it to loopback in `on_boot`, and inject frames from
-  template buttons (`fra-parts.yaml`, `frb-parts.yaml`). ufm01 enters its active stream by itself when a 1 s

-
-- `ld6-parser-cases.yaml` (used by `ld6-common.yaml`, which turns the query answers off): good, byte by byte (one

-  (copy it with another name for the base build). `run.sh NAME TREE` builds, flashes over serial and captures,
-  and fails without a `CASE done` line.
-- Garbage that contains `01` right before a frame loses that frame on dev and on the PR (a false header, no rescan).
-- Full component A/B: `ld6sim.hpp` also answers every query with a fixed report (delay, sensitivity, trigger,
-  installation, Z range, low power, low power sleep, both area reports, version); `ld6x-common.yaml` has the full
-  entity set and runs the parser cases too (`ld6x.yaml` is its run file); `ld6drive.py HOST` presses every button,
-  sets every number and select and toggles every switch over the API. Run it with `ERASE=1 DRIVER=ld6drive.py
-  scripts/uart_sim/run.sh NAME TREE 100`: switch and select states and the area id are stored preferences, and a previous build's run changes the
-  next build's boot state.
-- `m4-common.yaml` and `m5-common.yaml` run the same fake against `ld6004`: target and area reports, work status and
-  radar on/off reports, malformed reports, and the point cloud and target display switches across a reboot
-  (`m5` reboots once and checks the restored switch states). `m4.yaml` and `m5.yaml` are the run files, and like
-  `ld6p.yaml` each can be copied with another name for the base build. Run m5 with `ERASE=1 run.sh NAME TREE 75`: the boot
-  counter and switch states are stored preferences that survive a flash, and the second boot's `CASE done` comes
-  about 49 s after reset. Only the second boot logs `CASE done`, so a skipped reboot fails the run.

-## Music Assistant through sendspin
-
-`templates/usb-audio-sendspin-s3-eth-dut.yaml` overlays the template above with the Apollo CAST-1 wiring: resampler
-speakers into a mixer whose inputs never time out, `speaker_source` media player with the sendspin source, and
-`sendspin: unpaired_access: true`. A `media_player: platform: speaker` is not a media-source consumer and gives
-"Player over its buffer", no audio. Music Assistant finds the device by mDNS within 15 s of boot.
-
-Read the result from the device, not only by ear: sendspin's sync task logs `Lost sync (N us off)` (DEBUG, tag
-`SsSync`) for every correction over 5 ms, a positive N inserts that much silence, and each one is an audible click.
-For the chunk lead histogram, edit the managed library in the build directory,
-`.esphome/build/<name>/managed_components/sendspin__sendspin-cpp/src/sync_task.cpp` (an `SS_LOGD` before the
-late-chunk skip in `decode_chunk()` printing the chunk's lead against `new_audio_client_playtime`), update only that
-file's `size` and sha256 `hash` in the component's `CHECKSUMS.json`, and compile again; deleting `.component_hash` or
-recomputing it makes the manager refuse or refetch. Check the edit is in the image with `strings firmware.ota.bin`.
-A lead below -5 ms makes the library skip the whole chunk; an I2S speaker keeps it within 0.1 ms of zero, which is
-the figure a USB speaker has to match.
-
-Gotchas: wait two minutes after a reboot before the measured stream (safe mode's boot counter write stalls the cores
-for about 140 ms once, 60 to 75 s after boot); with the serial console on, a DEBUG log line per report saturates
-UART0 and trips the task watchdog, so use `logger: baud_rate: 0` and the API log; two overlapping `esphome logs`
-captures double every count; and every audio test must include a pause and resume cycle, since a stream end that
-leaves less than one transfer parked in the driver was what hung the speaker after #11728 merged.
-
-## Controls
-
-Apollo CAST PRO-1 (`templates/cast-pro-1-sendspin-control.yaml`): `Core.yaml` next to it is
-`Integrations/ESPHome/Core.yaml` from ApolloAutomation/CAST_PRO-1, which also defines the `version` substitution.
-Keep its framework log level at ERROR (DEBUG floods driver output and trips the watchdog); the package reboots itself
-into Ethernet-only once it sees a link and appends the MAC suffix to the name. `wifi: enable_on_boot: false` keeps
-sendspin off Wi-Fi.
-
-Nabu Casa Connect AUX-2 (a pre-production unit): build from `packages/aux-2-pre-prod.yaml` at NabuCasa/aux-2 commit
-283f2e64 (dropped in bde41e01), not the public `aux-2.yaml`, whose W5500, codec and I2S pins differ (the public one
-reads W5500 chip ID 0x00 and fails the codec's I2C writes). Point its local `external_components` source at
-`github://NabuCasa/aux-2@main`. Templates `aux-2-preprod-stock-dut.yaml` (I2S codec) and
-`aux-2-preprod-usb-audio-dut.yaml` (the USB speaker as the mixer output via `!extend mixing_speaker`). The console is
-the CH343 (1a86:55d3); first flash over it, OTA after. Forcing the Wi-Fi flag off with `restore_value: no` boot-loops
-when Ethernet fails, so let the package switch itself.

-Covers every path that reads an entity's icon or device class: the native API listing, MQTT discovery, the web_server
-`/events` listing and REST endpoints, and `dump_config`. `templates/entity-icon-dut.yaml` (ESP8266 board with wifi,
-encrypted api, ota, web_server and mqtt against a local broker) carries a sensor with a 63 character icon, one with no
-icon or device class, an internal sensor, and binary_sensor, switch, button, text_sensor, number, select, event, cover
-and text entities with icons and device classes. The per-run file supplies `name` and `broker_ip` through
-substitutions. Flash the PR and base builds under different names, then from the scratch directory:
-
-```sh
-scripts/entity_icons/readback.sh DEVICE_IP KEY NAME BROKER_HOST cap-NAME.txt   # once per build
-scripts/entity_icons/compare.sh ic-base ic-pr                                   # api, web, mqttn, dump all identical
-```
-
-`readback.sh` takes about 25 s once the device is on the network: 12 s of `mosquitto_sub` on `homeassistant/#` and
-`NAME/#`, the API listing (`api_list.py`, one JSON line per entity with icon, device class, unit, options and event
-types) and `web_dump.py` (6 s on `/events`, keeping only the listing rows that carry `domain`, then a GET of each
-listed id with `?detail=all` and one retry, because the ESP8266 async server occasionally leaves a request unanswered
-within 5 s). The web ids are `domain/Name`, not object ids, and `/event/<name>` has no GET handler (404 on every
-build). `mqtt_norm.py` drops the `dev` block (compile time) and the `NAME/debug` topic (heap probe), so a clean run
-differs in nothing. `dump_config` prints icons and device classes only for some domains; button, event and
-binary_sensor icons never appear there.

-Found with this flow on 2026-10-21: since #19577 every ESP8266 `web_server` build that lists a cover, climate, lock,
-valve, update, alarm_control_panel or water_heater entity reboots with `Exception (3) LoadStoreErr` in
-`json::linked(const char *)` (the ROM `strlen` on a flash address), fixed by #21316. The cover in the template keeps

-  station came back; several reason 2 before one join are rejected reconnects.
-- DUTs (`wdbk.yaml` BK7238, `wdcb.yaml` CB3S, both on `wd-common.yaml`) list the AP at priority 10 and the main
-  network at 0, and reboot 30 s after joining the AP and 150 s after joining the main network. So they move to the

-  ends. `run.sh BUILD` flashes the AP, does OTA for the CB3S and a serial flash for the BK7238, then captures one AP

-  not switch to WPA2/WPA3 (`AP CONFIG FAILED`), a DUT missing from the AP events (`DUT_MACS`) or a BK7238 that never

-AP start. After 19 minutes the DUTs run `wifi.configure` to the main network; that keeps the static IP, so the next
-OTA needs the host to have an address on the bridge's subnet as well (an interface alias). The CB3S log is on UART1

-default; pick one your normal network does not use), and `dut-common.yaml` gives the device under test that AP at
-priority 10 plus your normal network, logs every `wifi_info` ssid and channel update (with the channel the component
-reports and whether it is connected), and cycles `wifi.disable` and `wifi.enable` every 90 s. `run.sh LABEL` (env
-`TREE`, `PORT`, `AP_PORT`, `SC`, `PY`, and `BENCH_CHANNEL` when the AP is not on 11) flashes the device and captures 420 s while it takes the AP down with
-`esptool --port <AP port> --after no-reset chip_id` (the board stays in the bootloader) and back with
-`--after hard-reset`. The channel sensor must follow every move between the two networks: the run passes when the
-connected channel starts and ends on the bench channel with another channel in between.
-
-- Dropping the AP under a connected device gives a `Beacon Timeout` link loss.
-- The 90 s interval fires once right after boot.
-- A `Disconnected ... Association Leave` right after `Connecting to` is the aborted attempt, not a missed connect.

-  tag every other cycle and a counter 0 boot frame. It models the old shared duplicate counter (`base`) and the per
-  device one (`pr`) and prints the expected publish counts.
-- `xbinject.yaml` (ESP-IDF devkit) includes `frames.hpp`; an `interval:` builds a `BLEScanResult` and calls
-  `global_esp32_ble_tracker->gap_scan_event_handler(r)`. `count.py` counts the `Got Xiaomi` blocks (sensor
-  publishes are not logged at DEBUG) and compares them with `expected.json`.
-- On ESP32 the tracker's own triggers sit in `listeners_`, which runs before `neutral_listeners_` (the
-  ble_device_base devices), so an `on_ble_service_data_advertise` never sees what a Xiaomi listener did to the
-  shared data. Check that directly: `xb_rewrite_probe(id(xa))` builds an `ESPBTDevice` with `parse_scan_rst()`,
-  calls the component's `parse_device()` and logs the service data before and after (`[probe` lines).
-- `run.sh inject pr|base` builds, flashes, captures and prints PASS when the counts match that build's model and,
-  on the PR build, the probe's service data is the same before and after `parse_device()`.
-  Base dropped a second device's frame with the same counter, the frame after a bad tag and a first frame with
-  counter 0, and rewrote the shared data in place; the PR fixed all of them.
-
-## Over the air with a second ESP32

-  `gen.py --ota`. Per frame: stop advertising, `esp_ble_gap_set_rand_addr`, `config_adv_data_raw`, start
-  non-connectable advertising with `own_addr_type` random, 20 ms interval, 250 ms dwell. Random static addresses
-  need the top two bits set, so these use C4:C1:38 instead of A4. `esp32_ble:` alone brings up the stack. The
-  web_server button starts a run: `curl -X POST -d "" http://<advertiser>/button/start/press` (no body gives 411).
-  Its `failed sends` sensor counts only GAP calls rejected when queued; a frame the controller drops later shows
-  up as missing publishes in `count.py`, the same as radio loss.
-- Receiver: `xbrecv.yaml` on the devkit, passive scan with window = interval = 100 ms. `run.sh ota pr|base` (with
-  `ADV` set) flashes it, resets it with a capture and presses start 18 s later, so the counter 0 boot frame is the
-  first one it hears.
-- Each frame arrives about 4 times; the counts matched the injection run exactly apart from one radio loss, so the
-  over the air comparison allows two missing publishes per tag.

-## zwave_proxy frame checksums on a live proxy (#20922)
-
-A Z-Wave proxy (ESP32-S3 with the module on `usb_uart`) is a live device: flash it over OTA and read logs
-over the API, there is no serial console because the native USB is the host port for the module, so the
-boot-time `GET_NETWORK_IDS` exchange is never captured. Home Assistant's Z-Wave JS holds the single API
-subscription (it polls `0x3B` every 30 s and resubscribes after every reboot), so do not subscribe from a
-script, and keep the device `name:` so it stays on Z-Wave JS; give each build its own scratch directory
-instead.
-
-1. `logger: level: VERY_VERBOSE` with `logs: zwave_proxy: VERY_VERBOSE` and DEBUG for the rest: the
-   `Sending:`, `Received frame:` and `CHECKSUM Received ... Calculated` lines are `ESP_LOGVV`, which needs
-   the compile-time level.
-2. `md5` the two `firmware.ota.bin` files to be sure the A and B builds differ, then `esphome upload
-   --device <name>.local` and a `timeout 330 esphome logs --device <name>.local` capture started right after
-   the OTA to catch the resubscribe traffic.
-3. `scripts/zwave_proxy/verify_checksums.py <captures>` recomputes the XOR (init 0xFF, LENGTH..payload) over
-   every logged frame and counts bad checksums and ACK/NAK sent and received; `scripts/zwave_proxy/devinfo.py
-   <name>.local` prints the firmware version, compile time and the Home ID from the API (a Home ID proves the
-   device-built `GET_NETWORK_IDS` frame was accepted at boot).
-4. Pre-existing: one `zwave_proxy took a long time for an operation` warning on the first frame after the
-   log client connects, caused by VERY_VERBOSE logging; it appears on dev too.
