+
+No MIDI hardware needed: `templates/ble_midi/midiperi.yaml` turns a second ESP32 (an S3 with ethernet, so the
+API stays reachable while BLE is busy) into a BLE MIDI peripheral with `esp32_ble_server`: the MIDI service
+advertised, the MIDI characteristic with read, write, write without response and notify, an `on_write` that logs
+the bytes, buttons that notify hand built packets (channel messages, two messages in one packet, running status,
+SysEx in one packet, split over two, oversize, cut short, clock, aftertouch, orphan data bytes, a 50 packet burst)
+and a restart button for the disconnect test. `midicli.yaml` is the component test config on a classic devkit with
+`wifi:`, `api:`, the peripheral's BLE address in the `peri_mac` substitution, given on the command line with
+`-s peri_mac <mac>` (the base MAC plus 2, printed by `esp32_ble` in `dump_config`), `on_sysex` and `on_message` lambdas that print the bytes, debug sensors and out of range send
+buttons. Drive both over the plaintext API with `scripts/modem/mdrive.py HOST LOGFILE press:NAME wait:S` 3 s
+apart and compare the peripheral's `TX` and `RX` lines with the client's decoded lines. Gotcha:
+`ble_server.characteristic.set_value` latches the value of its first play and re-applies it before every notify,
+so the peripheral script sets the value from a lambda (`id(midi_io).set_value(std::vector<uint8_t>(pkt));
+id(midi_io).notify();`). At VERBOSE the client logs four lines per message, so a burst shows an
+`esp32_ble took a long time` of a couple of seconds that is the serial port, not the parser.

+## Interrupt driven base class (#21469, #21468)

+Any device with a PCF8574 input expander whose INT line goes to an ESP32 GPIO works; the inputs should change
+during the test (end switches on a gate or cover are ideal). Before flashing, check with `nm` that
+`gpio_expander::interrupt_pin_isr` lands in IRAM (0x4008xxxx on a classic ESP32). Then confirm `dump_config` lists
+the interrupt pin and the input states match reality, and that the `pcf8574` entry is absent from the runtime stats
+while idle (its loop is disabled). Drive the inputs (for a cover, `cover_command(position=1.0)` and then `0.0` over
+the API, waiting for each end state): every input edge should log, `pcf8574` should show a small count in that
+minute's stats and vanish in the next. For a device that cannot be reached physically, boot the same code on a
+bench board first and keep a merge base image built as the fallback; an ESP32 bootloader without rollback support

+## PNG decode time limit (#21364, #21391)
+
+The same server also serves any plain file in its www directory by name (404 for a missing file or a path
+outside it). `scripts/online_image/make_big_pngs.py <www>` (after `make_images.py`) writes a 320x240 gradient (618 B, also as `ok.png` so the misbehaviour cases carry a
+real multi-row PNG), a flat 640x480 PNG (1.6 KB for 307200 pixels), 231 KB of noise and a JPEG. The device is
+`templates/online-image-dut.yaml` with `type: BINARY` on the main image (a 640x480 RGB565 does not fit a classic
+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/remote_base/run.sh LABEL B N` (`TREE`, `P32` or `P66`, `SC` in the environment) writes the run file from the
+template, builds and flashes it from `TREE` (`esphome run --no-logs`), finds the IP and runs `rbdrive.py IP N`, which segments the API log by the
+markers and prints what each sent frame decoded as.
+
+- ESP32: `remote_transmitter` and two `remote_receiver`s on the same GPIO (`allow_other_uses`), carrier 100%, no
+  inversion. RMT reads its own output, every frame decodes. Second receiver `dump: [nec, raw]` shows raw runs only
+  where no primary matched.
+- ESP8266: the transmitter sends with interrupts off, so a receiver on the same pin sees nothing. `softtx.hpp`
+  bit-bangs frames built with each protocol's `encode()` with interrupts on, and an `interval` sets the pin back to
+  OUTPUT after the receiver's setup. Bit-banged NEC decodes as NEC about 2 of 3 times (timing), on every build.
+- Dish never decodes in loopback on dev either. Pronto matches every frame, so raw on `dump: all` never prints.
+- API log lines can drop under bursts; rerun with more rounds before calling a shortfall.
+- `register_dumper()` returns nothing, so the config logs `ext dumper register called`, not whether it stuck. On dev
+  the list has a fixed size and a dumper beyond it is dropped with `No dumper slot` (ERROR); judge by that line and by
+  `ext dumper saw` counts in the `rbdrive.py` table, which only appear when the dumper is really registered.
+  `rbdrive.py` exits 1 when the external dumper saw no frame, so a build that rejects the registration fails the
+  drive; set `EXPECT_REGISTER=1` on `run.sh` to also fail the run on any `No dumper slot` line.

+# Simulated UART sensors on a classic ESP32 (#21449, #21446)
+
+No sensor needed. `templates/uart_sim/sim.hpp` (included with `esphome: includes:`) has frame builders for wts01,
+ds1603l, sm300d2 and ufm01, `sim::loopback(id(uart))` (ESP-IDF `uart_set_loop_back` on the component's own UART),
+`sim::send()` that logs the bytes, and `sim::probe`, a SEN0465 responder polled from a 10 ms interval. The run files
+`fra.yaml`, `frb.yaml` and `frc.yaml` set the name and include `fr-common.yaml` plus their `fr*-parts.yaml` as
+packages; copy them with a different name (`frabase` and so on) for the base build.
+
+- 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
+  interval streams frames during its 2 s startup wait.
+- Request/response sensors: cross-wire two UARTs through the GPIO matrix (UART1 tx 25 rx 26, UART2 tx 26 rx 25,
+  `allow_other_uses: true` on all four pins); the second UART runs the simulated device (`frc-parts.yaml`).
+  A select sets the probe's misbehaviour (tail, FF tail, silent, split, wrong gas).
+- Polled readers: run `update()` from a script and log `micros()` around it to measure blocking
+  (sm300d2 on dev blocks about 104 ms on an empty buffer).
+- The logger stays on UART0, so three builds cover five components. Drive with `scripts/uart_sim/frdrive.py HOST
+  LOG press:NAME sel:NAME=OPT num:NAME=V wait:S`, or `scripts/uart_sim/run.sh NAME TREE SECONDS OPS...` (build
+  and flash from TREE with `esphome run --no-logs`, capture, drive; `PORT` and `SC` in the environment).
