-- `scripts/xiaomi_ble/gen.py` writes `frames.hpp` and `expected.json`: plain MiBeacon (0x50), encrypted v5 23 byte
-  with MAC and 19 byte without, real AES-CCM (`cryptography` AESCCM, tag 4, AAD 0x11, nonce = MAC reversed + pid +
-  cnt + 3 byte ext counter), ATC (13 byte, big endian) and PVVX (15 byte, little endian) 0x181A frames, a corrupted
-  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
-
-- Advertiser: an ESP32-S3 with Ethernet (OTA over Ethernet), `xbadv.yaml` with `adv_frames.hpp` from
-  `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.
