What the layers do
- QLink
- Cryptographic adjacency. Neighbours are proven, not guessed from ARP.
- DNI
- Self-certifying, expiring topological identifiers — locators / handles, not forever-who from a path.
- QRoute
- Intra-realm link state and inter-realm path vector.
- QResolve
- DID / content / resource resolution without DNS-as-who. Optional domain names remain handles only.
- QPolicy
- Consent, capability, deontic authorization.
- QSession / QSync
- Encrypted datagrams and streams; signed bounded Q42 / CRDT exchange.
