Brain pattern marketplace

Starter patterns from the teams and people who opt in. Install a pack and your fresh repo gets a baseline of fingerprints to match against. Once your own repo hits one of those patterns, the "N orgs have hit this pattern" line appears, and the count grows as you import more signers.

Team pattern packs are cryptographically signed by their publisher (ed25519), and your local installer refuses any pack whose signer key is not in your trust list. Creator brains, listed further down, carry no signature yet: they graft into your own brain as proposals you review, and each card says whether a signer identity was checked.

Packs are trust-ranked by default. Click any trust chip to see the four components a rating is built from: signature verdict, install count, install success rate, post-install survival. A team pack shows its install count only once five separate teams have installed it; a creator brain shows a plain total from the first install on. Only the first two components carry evidence today, so packs read unrated rather than showing a fabricated zero, and the default order falls back to the listing order until a pack is rated.
