Rework top-level README: add badges, status/roadmap section, config
search path docs, minimal two-node example with transports, DNS setup
instructions with systemd-resolved and resolv.conf examples, and
connectivity test walkthrough.
Replace ASCII document-relationship diagram with SVG in design docs.
Change DNS resolver default from disabled to enabled (port 5354).
Update config merge to allow higher-priority configs to disable it.
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- Remove outdated sections: indirect partition note, integration test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
