Two independent defects, both found by the audit and both silent. ⛔ IMAGES NEVER REACHED BLUESKY. hpp returned `blobs: null` from a booted node unless the DID used the overlay backend — favela-host sets none, so that is every DID it mints — while the real store sat in scope already serving three other surfaces. Only an IN-PROCESS consumer reads that field, and the projector is the first one. Measured: 11 posts in the atproto repo, none with an image; the same posts on the fediverse with their jpegs attached, because that projection never asks for a blob store. ⛔ BANNERS NEVER REACHED ANYTHING. The banner shares the avatar's store on purpose and inherited its 512 KiB cap, which the source itself calls a thumbnail policy. A banner is a wide header and does not fit, so the upload threw — after the avatar in the same submission had already saved, which is why it read as "the avatar works". The live fediverse actor had `icon` set and `image` null, and the atproto profile had no banner. Every link in the chain was correct; only the cap was wrong.
