Verifiers:
tools/verify_proof_packet.py — locks in §6.5. Toggles
Reticulum.__use_implicit_proof to test both modes; confirms
Identity.prove emits 64B (implicit) or 96B (explicit) proof
body; PacketReceipt.validate_proof accepts both lengths and
rejects an 80B body.
tools/verify_link_handshake.py — locks in §6.1, §6.2, §6.3, §6.6.
Most importantly verifies the previously-corrected §6.2 LRPROOF
body order (signature(64) || responder_X25519_pub(32) ||
[signalling]) and §6.3 link_id offsets (N=2 for HEADER_1) by
actually building a Link initiator-side, capturing the
LINKREQUEST raw bytes, computing link_id by the spec recipe,
running validate_request inline (since the upstream wrapper
swallows exceptions), and confirming the responder's LRPROOF
bytes match the spec layout. This was the single most
interop-critical correction we made.
tools/verify_rnode_split.py — locks in §8.3. Pure-function
re-implementation of the canonical TX and RX state machines
from RNode_Firmware.ino:359-446 + 716-742; tests header-byte
layout, single-frame TX, split-frame TX (300B → 254+46 with
shared header byte), all four RX state-machine cases (a/b/c/d
from the spec table), and end-to-end TX/RX round-trip at
sizes 50, 254, 255, 300, 508.
tools/verify_msgpack_quirk.py — locks in §9.3. Confirms umsgpack
distinguishes str (fixstr/0xa5) from bytes (bin8/0xc4); confirms
LXMF.display_name_from_app_data parses bytes-encoded display
names correctly and silently returns None (not crash) on
str-encoded ones, matching the bug-tolerance documented in §9.3.
All 11 verifiers pass against RNS 1.2.0 / LXMF 0.9.6.
Plus:
- SPEC.md frontmatter: 'Last verified against' line per agent.md §7.
- flows/receive-propagated-lxmf.md: closing half of the propagated
LXMF lifecycle. /get listing query, fetch query, ack-and-purge
via the have_ids slot, message-bundle unpack and dispatch
through lxmf_delivery.
- tools/README.md status table refreshed; flows/README.md flips
receive-propagated-lxmf.md to ✅.

# Verifier scripts
|
|
|
|
Self-contained Python scripts that test claims in [`../SPEC.md`](../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:
