Reorganize FIPS design documentation from implementation-centric structure (routing, gossip protocol, wire protocol, transports) to protocol-layer organization with clear service boundaries. New documents (8): - fips-transport-layer.md — transport layer spec - fips-link-layer.md — FLP spec (peer auth, link encryption, forwarding) - fips-session-layer.md — FSP spec (end-to-end encryption, sessions) - fips-ipv6-adapter.md — IPv6 adaptation (TUN, DNS, MTU enforcement) - fips-mesh-operation.md — routing, discovery, error recovery - fips-wire-formats.md — consolidated wire format reference - fips-spanning-tree.md — tree algorithm reference - fips-bloom-filters.md — bloom filter math reference Rewritten (2): - fips-intro.md — breadth-first intro with layer model diagrams - fips-software-architecture.md — slimmed to stable decisions Updated (3): - spanning-tree-dynamics.md — removed stale root refresh, aligned terminology - fips-configuration.md — fixed priority type (u16 → u8) - fips-state-machines.md — synced code examples with codebase Deleted (6): fips-transports.md, fips-wire-protocol.md, fips-gossip-protocol.md, fips-session-protocol.md, fips-routing.md, fips-tun-driver.md (content absorbed into new structure)

# FIPS Design Documents
|
|
|
|
Protocol design specifications for the Federated Interoperable Peering
|
|
System — a self-organizing encrypted mesh network built on Nostr identities.
|
|
|
|
## Reading Order
|
|
|
|
Start with the introduction, then follow the protocol stack from bottom to
|
|
top. After the stack, the mesh operation document explains how all the
|
|
pieces work together. Supporting references provide deeper dives into
|
|
specific topics.
|
|
|
|

|
|
| [fips-link-layer.md](fips-link-layer.md) | FIPS Link Protocol (FLP): peer authentication, link encryption, forwarding |
