Simplify the while check and name its condition in one helper

The condition's name and place in the file come from one helper, also for a list condition, without the private config location formatter. The fix text is shared by the error and the warning, and the check stops at the first action that waits.

- Real output rate: INT edges per 10 s window. Forced mode gives one edge per update.
- Settling: the bench cannot make a pressure step, but the soft reset in setup restarts the IIR filter with an
-  offset, so the first readings after boot show its step response (50 Hz with 128x settled in about 8 s).
- Reset behind the driver: `--reset-at` writes CMD 0x7E = 0xB6 at those seconds; a driver that handles it logs that
-  the sensor was reset and restores the registers.
- Start write faults (`--fault --kinds`, one letter per event at 30 s and then every 20 s): `N` the next start write

-## Counting
-
-Replace the global `operator new` in an `esphome: includes:` header on ESP32 (Arduino or ESP-IDF) and log the
-delta from an `interval`. Compare a PR build with its base on the same flow; the rate per second shows churn.
- The ESP8266 core defines `operator new` non-weak. `-Wl,--wrap=_Znwj` worked in a sensor-only config but
-  boot-looped a neopixelbus config (alignment fault in the wrapper), so report free heap only there.
- `vec = {}` keeps a std::vector's capacity (it is an initializer_list assignment); only
-  `std::vector<T>().swap(vec)` or `clear()` plus `shrink_to_fit()` frees it. Seen as heap that did not come back
-  after a WLED effect stopped.
-
-## Callers
-
-`scripts/heap_alloc/`:
- `allocring.hpp` counts every `operator new` and, once armed, keeps the first 1024 with their size, time and
-  five caller PCs, about 28 KB of RAM. It disarms itself when full. The frame walker
-  (`esp_backtrace_get_next_frame`) exists only on Xtensa (ESP32, S2, S3); on RISC-V chips entries keep size and
-  time without callers. Aligned `operator new` (`std::align_val_t`) is not replaced, so it is not counted;
-  nothrow `new` goes through the replaced one.
- `allocring.yaml` (package, substitution `alloc_arm_s`) arms it that many seconds after boot and adds a
-  "Dump allocations" button that logs what was kept. The press stops recording until the next reboot, so
-  reboot (or reflash) before each run; a second press returns the same entries.
- `alloc_marker(a, b)` from a lambda writes a marker entry, for example on each cover operation change, so the
-  dump splits into phases.
- `dump.py HOST OUT` presses the button and writes the dump to a fresh OUT, pressing again until the header
-  and every entry arrived (a late log subscription or dropped log lines). `decode.py LOG ELF [ADDR2LINE]` prints each entry with its callers as function and file:line, and exits 2
-  when the recorder never armed, an entry was still being written, entries are missing, repeated or out of
-  range, no Xtensa entry has a caller, the ELF is from another build (the buffer address in the header differs), or the buffer
-  filled. A PR build and its base can share that address, so copy each build's `firmware.elf` next to its dump. On RISC-V it prints sizes and times only. It reads only the newest dump in the file. The ESP-IDF ELF is `.esphome/build/<name>/build/firmware.elf`.
- `cycles_cover.py HOST N OUT` waits for the "Allocation recorder armed" binary sensor, then moves the first
-  cover to the far end and back N times (`cover_command(position=...)`, waiting for idle each way) with a states-only API client, then saves the dump the same way. It exits 2 when a move
-  never reached its position.
-
-Findings:
- Arm well after boot: the scheduler regrows its storage once after the freelist trim (see `scheduler.md`).
- Repeat the action several times in one session and count only what comes back. On a ratgdo cover (an external
-  component, ESP32 ESP-IDF) the first door open after boot allocated 18 times: four 36 B SchedulerItems,
-  `to_add_` and `items_` growth, and the API `DeferredBatch` vector. Cycles 2 and 3 allocated nothing.
- Keep the API client out of the count (see `api.md`): connect before the run, subscribe to states only, and

- `v6hf.yaml` adds a `HighFrequencyLoopRequester` (a busy main loop, as with a display or audio).
- `v6inject.yaml` links with `-Wl,--wrap=esp_netif_action_connected` and defines `V6_INJECT`; the wrapper in
-  `v6probe.hpp` sleeps 300 ms in the event task before esp-netif brings the station interface up, after the wifi

-  boots without link-local, SLAAC or a connection, connection timeouts, and median and worst times.
-
- Check the network first: a computer on the same network shows an `autoconf` IPv6 address when a router advertises
-  a prefix. SLAAC arrived about 2 s after link-local on the test network.
- The natural race did not show: no failure in about 160 boots on the S3 (normal and busy loop) and the C3 without
-  the fix. esp_event runs handlers in registration order and the wifi component registers before esp-netif, but the
-  event task reaches esp-netif's handler within microseconds. Only the injected delay reproduced the failure.
- An extra event handler registered from `on_boot` cannot inject the race: it runs after esp-netif's handler, when
-  the interface is already up. Wrap the esp-netif call instead.
- `wifi.disable` removes the addresses, so the reconnect phase creates link-local again on the same path.
- Count failures by the probe's `ll=0` too, not only by the warning: the USB console drops lines.

-Bench: ESP32-PICO-D4 (`board: pico32`, ESP-IDF) wired to an MCP2518FD module with an ATA6563 transceiver: SCK GPIO25,
-SDI GPIO26, SDO GPIO27, nCS GPIO32, INT GPIO33, module 3V3/GND, CLK pin to GPIO34. No second CAN node, so everything
-runs in `LOOPBACK`, or with the controller forced into internal loopback behind the driver.
-
- **Read the crystal.** The module's can is marked `H20.00` (20 MHz) even though listings say "8 Mbps"; the PR default
-  is `40MHZ`. Loopback never leaves the chip, so a wrong `clock:` still passes at half the configured rates. Measure it:
-  `pulse_counter` on the CLK pin with `internal_filter: 0us` reads SYSCLK/10 (2 MHz) at reset. Older heads wrote 0 to
-  `OSC` byte 0, which set `CLKODIV` to /1 (CLKO = 20 MHz, still countable by PCNT).

-  cannot drain RX: FD depth 20, CLASSIC depth 32 + one overrun) and a PCNT unit on the CS pin, which counts SPI
-  transactions while the pin stays an output (`cs_mark`/`cs_report`: idle cost per second).
- `common-can.yaml` is the package; each config adds its `canbus` block and a `phases` script: `can-loopback.yaml`

-  then burst 48 and RTR inside the next 5 s check interval), `can-normal-busoff.yaml` (no node acknowledges, so the

-  `run.sh CONFIG LABEL [SECONDS]` builds, flashes, captures and prints the summary lines.
- Gotchas found: a refused `REQOP` (LISTENONLY or Restricted from LOOPBACK) leaves `OPMOD` unchanged and stalls TX;
-  the chip refuses LOOPBACK to CLASSIC directly (go through Configuration); after a chip reset TREC reads `0x00200000`

-## ESP8266 interrupt locks under Wi-Fi load (#22452, #22453)
-
-Code that holds interrupts off for long on the ESP8266 starves the Wi-Fi interrupt handler (reset signatures in
-`reference/boards.md`). `scripts/esp8266_lock_load/` is the shared harness for any component that takes such locks:
-
- `base.yaml` is the shared DUT base: reset reason and info logged at boot, `power_save_mode: none`, `web_server` for
-  the HTTP load, `api: reboot_timeout: 0s`.
- `one-wire.yaml` reads a DS18B20 on GPIO4 every 2 s and runs a bus search every `search_interval`; `busy_control:
-  "true"` replaces the search with the same busy time (13 ms) and no 1-Wire traffic.
- `ir-one-pin.yaml` is the remote_transmitter case (see [remote_base.md](remote_base.md)).
- `wifi_load.py HOST SECONDS PPS` sends 512 byte UDP datagrams to port 9 at a fixed rate plus back to back GETs of
-  the web_server page.
- `run.sh` builds and flashes a DUT, captures the serial log, runs the load and prints every reset reason (usage in its
-  header). A clean run has one BOOT line.
-
-Make one file per build with `substitutions: {name: ...}` and `packages: {t: !include one-wire.yaml}`, with
-`secrets.yaml` next to it, and give dev and the PR different names.
-
-Notes:
- Run each build for 45 minutes at 500 packets per second. Shorter or lighter runs often show no reset on either
-  build: one search every 5 s survived on both.
- The busy-wait control separates the lock from the CPU time. On #22452 it had no Hardware Watchdog in 45 minutes,
-  while the PR still had 2 (dev had 6), so the remaining resets came from the slot locks. All three builds had one
-  Software Watchdog, which is the busy time plus the load.
- A search with no sensor answering is much shorter than one with a sensor (about 190 slot locks per search with
-  one DS18B20), so test with a real sensor on the bus.
- A stale `secrets.yaml` gives `No networks found` and the run has no IP to load.
- The 1-Wire bus code is shared by every platform, so check a lock change on an ESP32 too: the same DS18B20 search
-  config on ESP-IDF with `bluetooth_proxy` scanning and the same load gave 0 resets and no missed searches on dev and

-Matches ha-all-common.yaml: one fixed entity_id entity and one wizard-linked entity per platform. The client
-subscribes to entity states, Home Assistant actions and Home Assistant state subscriptions, then:
-  A  sends Home Assistant states for the fixed entities (and for a wizard ID that is not set yet), commands every
-     writer, and checks that the wizard-linked ones send nothing;
-  B  sets every wizard input (WizardInputSetRequest), records the subscriptions the device sends for it, sends
-     states for the new IDs and commands the writers;
-  C  changes every wizard input to a second ID: old IDs must be ignored, new ones followed;
-  D  sends an invalid ID, which the device must reject.
-Prints canonical lines (SUB, STATE, ACTION, CHECK) so two builds can be diffed, and PASS or FAIL at the end.
