Gives stable names to what issue #134 showed gets conflated: Trusted peer
(invite-verified, operator decision), Discovered peer (learned from a
Trusted peer's advertisement, hard-capped at Observer — TRUST IS NOT
TRANSITIVE), Routing hint (what a Discovered peer actually contributes:
reachability, not trust), and Peer advertisement (the mechanism itself,
a feature not a leak).
Records the two rules that make the model sound (trust requires a
traceable operator decision; discovery is transitive, trust is not), why
advertisement exists (one invite makes a node reachable to the trusted
set without granting anything), and the deferred open questions: the
'don't advertise my peers' privacy toggle and UI tier vocabulary.
