lwIP-CE is a fork, a port, and a pile of platform-specific glue. This page keeps
the people, reference implementations, and standards links in one place.

Upstream lwIP
-------------

lwIP-CE is forked from lwIP. The upstream project remains the best reference
for general lwIP behavior and raw API concepts that still apply here.

AI-Assisted Tooling
-------------------

AI-assisted tooling has been used for limited engineering and drafting work,
including code review support, selected debugging sessions, and explanatory
prose organization. It is not treated as an authority for cryptographic claims,
standards compliance, or empirical results.

Human review, implementation decisions, test interpretation, and final
responsibility remain with the project author.
