Three deterministic vector files complete the test-vectors/ bootstrap.
Each regenerator pins every random source so output is byte-identical
across runs against a fixed upstream RNS / LXMF version.
- announces.json: two vectors (no-ratchet + with-ratchet) signed by
Alice. Determinism via patched Identity.get_random_hash + module-
local time.time shim inside RNS.Destination.
- lxmf.json: two opportunistic-LXMF vectors Alice -> Bob, captures
full plaintext (S5.2 layout) plus Token-encrypted ciphertext (S3).
Determinism via fixed LXMessage.timestamp, ephemeral X25519 priv,
and Token CBC IV.
- links.json: full Link handshake — LINKREQUEST + LRPROOF wire bytes,
derived link_id, ECDH shared secret, and HKDF-derived session key
that both initiator and responder MUST agree on. Determinism via
three queued ephemeral priv-key blobs (initiator X25519, initiator
Ed25519, responder X25519) consumed in source-call order at
RNS/Link.py:285, :286, :278.
Status table in test-vectors/README.md and tools/README.md updated to
reflect the completed bootstrap. todo.md cleaned up to reflect actual
state (the previous "Open ⚠️ items needing a runtime verifier" section
was stale — all three verifiers were completed earlier).

"_about": "Link handshake test vectors. Each vector records a full Reticulum Link handshake: LINKREQUEST (initiator -> responder) and LRPROOF (responder -> initiator). The ephemeral X25519/Ed25519 keys are pinned via the `inputs.*_priv_hex` blobs; both Ed25519 signatures are RFC 8032 deterministic so the resulting wire bytes are reproducible. A clean-room implementation can verify by: (a) packing a LINKREQUEST from the recorded initiator ephemerals and confirming bytes match `linkrequest_raw_hex`; (b) computing `link_id` per SPEC.md S6.3 (N=2 for HEADER_1) and matching `link_id_hex`; (c) packing an LRPROOF as the responder, with bob's identity Ed25519 sig over `link_id || responder_X25519_pub || responder_long_term_Ed25519_pub || signalling`, and matching `lrproof_raw_hex`; (d) running ECDH+HKDF on either side and matching `derived_key_hex`. Regenerate with `generator_script`.",
