-# 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 full contributor guide and the
-authority when it disagrees 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 `AGENTS.md` 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.
-
-## 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_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.
-
-## 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.
-
-## 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.
-- `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`.
-
-## 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.

Use this whenever a task asks to test, verify, reproduce, bench, A/B or soak a pull request, a branch or a crash on hardware, or mentions flashing, serial logs, esphome upload, a captive portal or fallback AP test, or results to post on a PR. Covers finding the serial ports, building from the right checkout, flashing each chip family (including the LibreTiny kits that stock tools cannot flash), bounded log capture, proven test flows and how to report results.

-# 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.
-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.
-
-## 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 as a table: build SHA, board and framework, what was driven, counts, result,
-   plus the `dev` control row and the exact flow in a `<details>` block. No credentials, no port names,
-   no IP addresses.

-## 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` |
-| 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]`: bounded timestamped
-  capture, 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.
-- `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.

-## Templates in `$SKILL/templates`
-
-- `dut-fallback-ap.yaml` (package): a device that never finds its network, falls back to its AP and
-  serves the captive portal. `example-dut.yaml` is the per-run file with the platform block.
-- `client-wifisave.yaml` (package): joins that AP, posts N bogus `/wifisave` requests, then the real
-  credentials from `!secret`. `example-client.yaml` is the per-run file. `bogus_saves: "1"` gives a
-  plain provisioning check.
-- Per-topic device configs, each described in `reference/recipes/<component>.md`: `online-image-dut.yaml`,
-  `usb-cdc-acm-dongle-dut.yaml`, `nrf52-preferences-dut.yaml`, `rtsp-waveshare-s3-eth-dut.yaml`,

-  `bk72xx-rtc-prefs-dut.yaml`, `bk72xx-crash-probe-dut.yaml`, `dut-ap-only-wipe-once-bk72xx.yaml`.
-
-## When something looks wrong
-
-- A capture stopped early or a line is missing: check the timestamps before trusting it.
-- 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.
-- `api:` reboots a board after 15 min without a client: `reboot_timeout: 0s` on `api:` and `mqtt:` for
-  soak tests.
-
-`reference/boards.md` has per-chip facts and crash decoding; `reference/recipes/` has the proven
-flows. Add new findings there.

-# Board facts
-
-Ports are not listed on purpose: they follow the USB hub port and change on every replug. Run
-`scripts/ports.py`.
-
-## 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`).
-- `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.
-
-## 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).
-
-## 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.
-
-## 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`.
-
-## 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.

-  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.

-
-- 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.

-## 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. RGB LED active low (red P0.23, green P0.22, blue P0.24),
-  button P0.18.
-- Adafruit ItsyBitsy nRF52840 Express (UF2 bootloader with S140, 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.
-
-## 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, 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.
-- 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).

-Counts that matter: `Requested WiFi Settings Change` (saves received), `Exiting cooldown early`, crash
-markers, boots (`Log initialized`), and the client's `bogus save status 200` and `real save status 200`.
-A healthy run: every save answered 200, one cooldown exit per save (two on the BW15, whose retry enters
-the adapter restart), no panic, and the real credentials connect the device within about 10 s.

-## 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

-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`.

-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

-
-`templates/usb-cdc-acm-dongle-dut.yaml`: logger on USB_CDC port 0, `usb_cdc_acm` interface 0 disabled,
-interface 1 echoing from a 20 ms lambda, 0x01-prefixed commands for burst, stream, flush, peek, line coding
-and counters. Build and flash with `dfu: true` through the app port; the dongle then shows three CDC ports:
-the board DTS node `cdc_acm_uart` (unused), `cdc_acm_uart0` (log) and `cdc_acm_uart1` (data), in that order.
-Capture the log port with `serial_capture.py`, drive the data port with `scripts/usb_cdc_acm/drive.py
-DATA_PORT` (11 cases, prints PASS/FAIL and a summary) and grep the log for `Opened`, `Closed`, `buffer full`,
-`flush result`, `line coding`. Boot lines are held in the driver's 1 KB ring until the host opens the port, so
-a capture started later still shows the first 1 KB of the boot and then a truncated line.
-
-With three CDC instances the Zephyr legacy stack's `CONFIG_USB_MAX_NUM_TRANSFERS=4` starves the last instance
-(each instance holds an OUT read and an IN ZLP), so interface 1 shows DTR changes but moves no data.
-`scripts/usb_cdc_acm/cdc_probe.hpp` (include it, call `cdc_probe()` from an interval) reads the Zephyr driver
-directly to tell a dead endpoint from a component bug. Raising the transfer pool to 8, or disabling the
-board's `cdc_acm_uart` node, fixes it. Design limit of the driver: `fifo_fill` holds `tx_ready` until the
-write callback and `write_array` drops when the ring is full, so a 64 KiB full-duplex echo loses one 64 byte
-tail on every buffer size.

-over the API, there is no serial console because the native USB is the host port for the module, so 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

-Lines are written as [HH:MM:SS]text with ANSI colour stripped and flushed one by one, so a shell
-loop can grep the file while the capture runs. If the port is missing or disappears (USB CDC boards
-re-enumerate on reboot) the script retries until the deadline, and follows the board by its USB serial
-number when it comes back under another device path.
-
-Never run an open-ended serial session: every capture has a deadline, and a flash on the same port
-needs the capture stopped first (pkill -f "[s]erial_capture.py" does not match the killing shell).

-        ## Use of AI in bug reports
-
-        AI tools are good at carrying out well-defined tasks, but they are not good at troubleshooting.
-        Please do NOT paste an AI-generated wall of text into the issue template - if the AI hasn't solved
-        your problem, its wild guesses are not likely to help.
-
-        Please DO include your own words and observations, compile/boot logs, and
-        especially a minimal reproducible example of your YAML configuration that demonstrates the problem.
-
-        It is however quite acceptable to use AI to translate your *own* report,
-        if you aren't a competent English speaker.
-
-        If you really think it will be useful to include an AI's analysis, preferably wrap it in a `<details>` block which will be collapsed by default.
-
-        If you are using AI to help solve a problem, rather than asking it to speculate about what the problem is,
-        it can be more useful to ask it to create a step-by-step troubleshooting procedure.
-        AI is also useful for generating boilerplate code, such as a minimal reproducible example of your YAML
-        configuration that demonstrates the problem.
-
-        Used properly, AI can be a useful tool to help you solve your problem, but don't let it get in the way.

-        On other platforms they are a plain `memcpy` and dereference, so no `#ifdef` is needed. Declare log tags with

-        end of `setup()` when the entities need a state at boot.
-    *   **A multi-step command sequence** leaves the step pending when the answer is malformed, so the existing

-    *   **Entities that each watch a register field:** one class taking register, shift, mask and match from a Python
-        tuple table, in typed `StaticVector`s sized by `cg.slot_counter`; not a template per bit, not a virtual
-        listener base (a second vptr per entity).
-    *   **A global feature define** says the code is compiled in, not that this instance uses it: keep the
-        per-instance check (`if (this->aux_device_ == ...)`) inside the `#ifdef`.
-    *   **Model-specific code** sits behind a define the Python side emits only for configs that use that model
-        (`cg.add_define("USE_SELEC_METER_EM4M")`), so the other models' builds leave it out; the runtime model check
-        stays inside the `#ifdef`.
-    *   **Failures after `setup()`:** `mark_failed()` is for `setup()` only. A runtime read or write failure
-        sets `status_set_warning()` and the next success clears it; writes skip work when `is_failed()`.
