swaitsandClaude Opus 4.7 d785e35919 feat(mdbook): publish spec via mdBook on GitHub Pages
Set up the protocol spec as an mdBook and add a GitHub Actions
workflow that builds it on every push/PR and deploys to GitHub
Pages on main. The repo is now both a machine-readable corpus and
a browsable, searchable site.

Structure changes (one-time, mechanical):

- Rename the spec source directory from `spec/` to `src/` to match
  mdBook's default convention. All 21 chapter files move; their
  internal relative cross-links are unchanged.
- Add `src/SUMMARY.md` as the mdBook table of contents, grouping
  chapters under Wire Format, Payloads, Cryptography & Identity,
  and Routing & Higher-Layer Protocols.
- Add `book.toml` at repo root: title, author, search enabled,
  fold enabled, edit-on-GitHub links, navy theme.
- Add `.github/workflows/mdbook.yml`: build on push + PR, deploy
  on push to main only (configure-pages + upload-pages-artifact +
  deploy-pages from actions/).
- Add `/book/` to .gitignore.

Reference updates so the old path is fully retired:

- Every `spec_ref` in `corpus/**/*.json` rewritten from `spec/` to
  `src/` (54 files).
- Schema description text and example path in
  `corpus/schema/test-vector.schema.json`.
- `README.md`: prominent link to the published site near the top;
  "What's Here" updated for the new layout.
- `CONTRIBUTING.md`: spec-editing instructions point at `src/`
  and note the SUMMARY.md requirement.
- `CLAUDE.md`: directory-layout notes updated.

CHANGELOG.md historical entries intentionally keep their `spec/`
paths since those record what the paths were at the time of those
commits.

After this lands, the user needs to enable GitHub Pages in repo
settings with source = "GitHub Actions" (one-time, manual). The
workflow will then publish to https://swaits.github.io/meshcore-spec/
on every push to main.

Verified locally: `mdbook build` produces a clean book/ tree with
all 21 chapters rendered and the SUMMARY-driven sidebar populated.

MeshCore Spec — Project Guide

What This Project Is

A specification and conformance test suite for the MeshCore mesh networking protocol. It contains:

  1. RFC-style spec documents in src/ (Markdown, using RFC 2119 language; this is also the mdbook source root)
  2. JSON test vector corpus in corpus/
  3. Validation tooling in tools/

Conventions

  • All binary data in JSON is uppercase hex (e.g., "0D00EFBEADDE"). Whitespace in hex strings is allowed and stripped on parse.
  • All multi-byte integers are little-endian unless explicitly noted otherwise.
  • Test vector IDs use the format {category}-{NNN} (e.g., ack-001, kiss-hw-003).
  • Spec sections are numbered 00- through 20- and use RFC 2119 keywords.
  • The C++ reference implementation at github.com/meshcore-dev/MeshCore is the source of truth for protocol behavior.

Key Protocol Constants

  • MAX_PACKET_PAYLOAD: 184 bytes
  • MAX_PATH_SIZE: 64 bytes
  • CIPHER_MAC_SIZE: 2 bytes
  • PATH_HASH_SIZE: 1 byte (default)
  • PUB_KEY_SIZE: 32 bytes
  • SIGNATURE_SIZE: 64 bytes
  • MAX_TRANS_UNIT: 255 bytes

File Organization

  • src/NN-topic.md — Spec sections, numbered for reading order (mdbook root)
  • src/SUMMARY.md — mdbook table of contents; new chapters MUST be added here
  • corpus/schema/ — JSON Schema for test vector validation
  • corpus/{layer}/{type}/ — Test vectors organized by protocol layer
  • tools/ — Python validation and generation scripts

Working With Test Vectors

Each JSON file validates against corpus/schema/test-vector.schema.json. Vector types: encode_decode, decode_only, invalid.
