Adds a new §5.9 "LXMF field constants and helper specifiers" that documents every numeric allocation in upstream LXMF/LXMF.py — the 20 top-level fields dict keys (0x01..0x0F + 0xFB..0xFF), the 20 FIELD_AUDIO mode bytes (Codec2 + Opus families), the 4 renderer bytes, the 7 propagation-node metadata keys, and the SF_COMPRESSION capability flag. Each entry is cross-referenced against the section that describes its byte-level shape where one exists (e.g. §5.9.2 for FIELD_IMAGE, §5.9.4 for FIELD_RENDERER). Verifier in tools/verify_lxmf_fields.py loads upstream LXMF (0.9.7 in this run) and confirms every constant numerically — and fails if upstream adds a new FIELD_/AM_/RENDERER_/PN_META_/SF_ constant that isn't yet enumerated in the spec. Per agent.md §1, this promotes the inventory from "implicit in code" to "verified against upstream." The byte-level value shapes for fields whose contents are application-defined (FIELD_EMBEDDED_LXMS, FIELD_TELEMETRY*, FIELD_FILE_ATTACHMENTS, FIELD_COMMANDS, FIELD_RESULTS, FIELD_GROUP, FIELD_EVENT, FIELD_RNR_REFS) are marked UNVERIFIED — future PRs should pin them with captured test vectors.

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 1.2.4 / LXMF 0.9.7:
| Script | Verifies SPEC.md section | Status |
|---|---|---|
