ESP32-family app and bootloader images (magic 0xE9) had no reader, so open_binary refused OTA downloads, app partitions and bootloaders. Add the esp-image container format behind inspect_artifact and extract_artifact. A pure decoder reads each byte once and keeps only fixed-size fields. Derived facts cover the chip, from a table cited to ESP-IDF v6.1; segment classification as ESP-IDF's should_map and should_load; checksum and appended SHA-256 results; app and bootloader descriptors; Secure Boot v2 signature blocks, observed and unverified; and undescribed trailing byte ranges. Truncation and undescribed bytes make coverage unknown. ESP8266 images are refused with a specific reason, and ciphertext stays unrecognized. Add the format to every target, Evidence, snapshot, live-summary and artifact vocabulary, document it, and add an optional verify:esp-images lane that compares esptool-built images with esptool image-info and espsecure signature-info-v2.
