## Coverage summary

- **88 footnotes total** in the Brief.
- **87 footnotes have at least one direct index reference.**
- **1 gap:** `[^70]` (rust-libp2p binary size GitHub issue #1051) — no index entry directly references that issue URL. The topic (rust-libp2p binary size) IS covered indirectly via `repos/rust-libp2p.md` §Binary size knobs + `articles/INDEX.md` dev-to-ahaoboy (general Rust shrinking), but the specific GH issue tracking libp2p sizing is not in the corpus. Refetch if precise issue evidence needed.

## Multi-coverage hot footnotes (≥3 index files)

These footnotes are referenced from many angles — useful when looking for a topic across mapper perspectives:

- `[^5]` (iroh FAQ / 90% direct) — `docs/INDEX.md` + `repos/iroh.md` + Brief §1 Rank 1
- `[^11]` (libp2p DCUtR 60% number) — `forums-wikis-videos/INDEX.md` + `docs/INDEX.md` + `repos/rust-libp2p.md` + `articles/INDEX.md`
- `[^28][^29][^30][^34]` (Magic Wormhole stack) — `articles/INDEX.md` + `docs/INDEX.md` ×2 + `repos/magic-wormhole.md`
- `[^35][^36]` (Ford 2005 P2P NAT paper) — `papers/INDEX.md` ×2 + `articles/INDEX.md` (cross-ref) + `forums-wikis-videos/INDEX.md` HN
- `[^41][^42]` (Quinn) — `repos/quinn.md` + `forums-wikis-videos/INDEX.md` HN (note: not in docs/INDEX.md — see README gap)
- `[^47]` (snow Noise) — `docs/INDEX.md` + `rfcs-specs/INDEX.md` + `forums-wikis-videos/INDEX.md` 34c3
- `[^58]` (Tailscale) — `articles/INDEX.md` (stub) + `docs/INDEX.md` + `forums-wikis-videos/INDEX.md`
- `[^82]` (2025 NAT measurement) — `papers/INDEX.md` (load-bearing for caveats #3 + #4 in README)

## Brief Open Questions (§4) — coverage check

The Brief lists 8 Open Questions. None of these have dedicated index entries (they're forward-looking design questions, not citable prior art), but adjacent material exists:

- Q1 (relay operator commitment): `repos/iroh.md` §Relay self-hosting answers the "how"; the "will we" is unresolved.
- Q2 (libp2p bootstrap strategy): `articles/INDEX.md` blog-ipfs-tech + `docs/INDEX.md` `docs-ipfs-tech-how-to-modify-bootstrap-list.html` show patterns.
- Q3 (pairing UX scope): `repos/magic-wormhole.md` (short codes) + `articles/INDEX.md` briarproject (QR) span the design space.
- Q4 (delivery semantics): `docs/INDEX.md` `handbook-scuttlebutt-nz-concepts-gossip.html` + `repos/vpn-cluster.md` headscale `change.Change` events show eventual-consistency models.
- Q5 (Nostr signaling relay set): `docs/INDEX.md` `nostr-watch.html` + `docs-rs-nostr.html`.
- Q6 (Veilid bandwidth): `repos/veilid.md` §Bandwidth/CPU profile (defaults inferred from config).
- Q7 (Windows code signing): no direct coverage.
- Q8 (CGNAT user UX): `papers/INDEX.md` arxiv-2510-27500 + `forums-wikis-videos/INDEX.md` HN birthday-paradox math.
