linxiv-p2p

P2P project sharing for linXiv: iroh transport + Keyhive capabilities + Beelay encrypted sync. The full protocol stack is implemented and tested behind feature flags so linXiv is ready the day Keyhive stabilizes.

Warning

This code is a personal implementation of a pre-alpha technology, always review code yourself before relying on it for any confidentiality or security reasons.

Layers

Module	Flag	What
sync	(default)	Persistent device identity, ALPN linxiv/sync/0, pasteable share tickets, plain automerge sync. Ship-quality fallback path.
auth	auth-keyhive	keyhive_core 0.5.0: per-project groups, signed delegations (Role::{Relay,Read,Edit,Admin}), revocation + PCS rotation, dual cross-signed device keys, access-check hook.
beelay	sync-beelay	beelay-core alpha moves keyhive-encrypted automerge changes as opaque commits over iroh, plus an iroh-blobs path for encrypted file transfer.

Test

cargo test                            # phase 1 (3)
cargo test --features auth-keyhive    # + capability layer (15)
cargo test --features sync-beelay     # + encrypted sync e2e (14, +1 ignored)
cargo test --features sync-beelay --release -- --ignored   # 5/25 MiB blob timings

Tests are offline (no relay/discovery). tests/beelay.rs::e2e_toy_project is the gate: create → delegate → sync → edit both sides → revoke → new content "undecryptable".
