Wire format diagrams:
- Add 24 SVG diagrams covering every FMP and FSP wire format: common
prefix, established frame headers, Noise IK handshake messages,
handshake flow, TreeAnnounce, AncestryEntry, FilterAnnounce,
LookupRequest/Response, SessionDatagram, Disconnect, SenderReport,
ReceiverReport, FSP complete message, SessionSetup/Ack/Msg3,
PathMtuNotification, CoordsRequired, PathBroken, and MtuExceeded
- Replace ASCII art in fips-wire-formats.md with SVG references
- Apply text edits to fips-mesh-layer.md, fips-mesh-operation.md,
fips-transport-layer.md, and fips-ipv6-adapter.md
Spanning tree dynamics:
- Add 12 topology SVG diagrams: node join (overview + 3-panel steps),
three-node convergence (4-panel), link addition with depth labels,
link removal, partition formation, and 6 real-world example diagrams
(office, mixed-link, two-site WAN topologies)
- Rewrite all code blocks to narrative prose with diagram references
- Add inline prior art attributions distinguishing Yggdrasil-derived
concepts from FIPS-novel contributions
- Add 3 new references (De Couto ETX, IEEE 802.1D, RFC 2328 OSPF) and
Prior Art summary
- Remove outdated sections: indirect partition note, integration test
gaps, DHT-based lookup reference
- Change "must elect a new root" to "must rediscover its new root"
Spanning tree design review (fips-spanning-tree.md):
- Rename "Root Election" to "Root Discovery" across docs
- Add "What Is a Spanning Tree?" introductory section
- Add parent selection intro explaining self-organization role
- Fix tree distance example: 4 hops, not 2
- Clarify timestamp field as advisory only
- Remove unimplemented ROOT_TIMEOUT and TREE_ENTRY_TTL from timing
parameters and implementation status tables
Bloom filter design review (fips-bloom-filters.md):
- Add "What Is a Bloom Filter?" intro section
- Rewrite Purpose section to frame filters as routing path identification
- Correct FPR analysis (old values were 3-50x overstated)
- Add Filter Occupancy Model based on network size and tree position
- Fix filter expiration to describe actual MMP-based cleanup
- Combine Scale Considerations with Size Classes after Wire Format
- Fix stale FPR values in src/bloom/mod.rs comments
Session layer review (fips-session-layer.md):
- Add inline prior art attributions: Noise Protocol Framework, WireGuard,
DTLS (RFC 6347), IKEv2 (RFC 7296), RFC 1191 PMTUD, Yggdrasil, NIP-44
- Replace warmup state machine ASCII art with SVG diagram
- Convert CoordsWarmup wire format code block to prose
- Add External References section with full citations
Level 5 implementation doc cleanup:
- Delete fips-software-architecture.md (redundant with protocol layer docs)
- Delete fips-state-machines.md (Rust tutorial, not protocol design)
- Add fipsctl command reference to README.md
- Update cross-references in fips-intro.md, docs/design/README.md,
fips-transport-layer.md, fips-configuration.md
Fixes:
- Correct fd::/8 to fd00::/8 in fips-session-layer.md,
fips-identity-derivation.svg, and fips-node-architecture.svg
- Fix config example MTU: 1197 → 1472 in fips-configuration.md
File organization:
- Move all SVG diagrams into docs/design/diagrams/ subdirectory
- Update all diagram references to use new paths
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.
