// bsky-inbound.test.js — a Spacedust link on a bound DID's post becomes an observation (hyper-social #82, I2b).
//
// ⛔ THE SAME OBSERVATION SHAPE AS THE FEDIVERSE (I1), so nothing on the node changes: kind, actor, subject (kept as
// observed), target (inverted to the identity's own favela post), activity (the identity the observation is undone
// by — here the linking record's at:// URI, which is what a Spacedust `delete` names).
//
// ⚠ The favela post behind an at:// rkey is found by recomputing tidFor over the identity's posts — tidFor is
// one-way (favela-bridge tid.js), so the caller supplies `postName(rkey)`.
