lxmf-update	Check upstream LXMF and RNS implementations for changes affecting the LXMF specification, run local verifier tools, and propose spec updates with citations.

LXMF update skill

Use this skill when asked to check whether the LXMF specification is current with upstream LXMF or RNS.

Sources of truth

Prefer, in order:

1. Upstream LXMF source code at a pinned release or commit.
2. Upstream RNS source code where LXMF behavior depends on Reticulum behavior.
3. Reproducible local traces and test vectors.
4. Upstream prose documentation, only when consistent with source behavior.

Required workflow

1. Determine the currently pinned upstream LXMF and RNS versions from SOURCES.md.
2. Check whether newer upstream releases or commits exist.
3. Identify changed files relevant to:
   • message packing
   • fields and flags
   • destination handling
   • identity/signature behavior
   • encryption behavior
   • propagation
   • delivery semantics
   • storage format if externally observable
4. Run the verifier tools in tools/.
5. Compare observed behavior against SPEC.md.
6. Produce a report with:
   • changed upstream files
   • affected specification sections
   • proposed edits
   • test-vector impact
   • unresolved ambiguities
7. Do not modify SPEC.md unless explicitly asked.
