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).

Verifier scripts
Self-contained Python scripts that test claims in ../SPEC.md against the upstream RNS / LXMF Python stack.
Conventions
- Each script verifies one claim or one related cluster of claims.
- Exit code 0 on PASS, non-zero on FAIL.
- Print a one-line PASS/FAIL summary plus a unified diff or hex dump on mismatch.
- Reference the SPEC.md section the script verifies in a docstring at the top.
Required environment
pip install rns lxmf
The scripts read RNS.__version__ at startup and print it in their output so a future reader can tell which RNS version a verification ran against.
Status
Populated against RNS 1.2.0 / LXMF 0.9.6:
