Rob cfd0d8249b Re-anchor against RNS 1.2.4 / LXMF 0.9.7 + track upstream distribution shift 
Upstream RNS 1.2.4 (2026-05-07) announces it is "probably the last
release that is also published to GitHub" — pip continues until rnpkg
is complete and RNS is self-hosting. All 13 verifiers pass against
1.2.4 / 0.9.7; no wire-format, signing, or protocol behavior changed
between 1.2.0 and 1.2.4, so the changes here are purely currency:

- Pin tools/requirements.txt to rns==1.2.4 / lxmf==0.9.7 so the
  verifier stays reproducible if upstream stops mirroring to PyPI
  before the migration is ready.
- Add an "Upstream distribution shift" watch-list to todo.md (local
  Reticulum node, repo destination hash, rnpkg install/upgrade
  commands, rsg signature verification, mirroring source citations).
- Bump SPEC.md frontmatter and re-anchor ~50 line citations across
  Identity.py, Transport.py, Resource.py, Link.py, Reticulum.py,
  Packet.py, and LXMF/* (Identity.py drift was the heaviest at +13
  to +31 lines; Transport.py was variable). Fix one numeric
  (MAX_RANDOM_BLOBS = 32 → 64) and one semantic (§6.6.3 LRPROOF MTU
  clamp citation pointed at the wrong location — corrected to point
  at the transit-relay clamp at Transport.py:1539-1556).
- Update §10.4 decompression-bomb hazard to note upstream's 1.1.9 cap
  adoption, with citations to Resource.py:686-691 and Buffer.py:95-97
  plus a "do not use one-shot bz2.decompress()" warning.
- Re-anchor 11 flows/ files (version pins + ~30 line citations).
- Bump version labels in tools/README.md, test-vectors/README.md, and
  4 verifier docstrings + 2 hardcoded print strings.

README.md

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
