m.image events in delivered messages are fetched as the receiving Persona, classified by magic bytes, bounded by size and header pixel count, and stored under IMAGE_STORE_ROOT/<persona>/<room hash>/<bytes hash>[.ext] (0640, dirs 2750). The delivery tuple gains index 11, nil or [path, mime, size, sha256]; the pending kind becomes gamecult.persona.chat_pending.v2 with Huginn's v3 golden bytes. Refusals keep the typed text line plus a fixed-word reason. The mouth test homeserver is answered in-process so the suite runs under a capped address space.

// Header-only image bytes for tests: just enough of each format for the mouth to sniff its type and size.
