The settled model: a community is a co-owned GROUP account (like bsky.art / blacksky) that OWNS its feed record; the record's `did` field is the getFeedSkeleton SERVICE, which — like every real feed (Discover→ did:web:discover.bsky.app, Artists→did:web:api.graze.social) — is a shared `did:web` (favela-web), NOT the group's own DID. The old code set `did: communityDid` (the group serving as its own feed engine) — the one thing no real feed does, and what made loser-club look like a feed-that-is-a-service. publishFeedGenerator now takes `service` (the did:web); the group stays the OWNER + name, the did:web is the invisible compute backend. Falls back to communityDid for legacy callers (back-compat). Full suite green. The co-owned-DID / StateBase machinery stands — loser-club is correctly a co-owned group; only this one record field changes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
