AXLink v0.1.0-alpha.1 – simulator prerelease

The first experimental AXLink simulator state (Codex phase): ordinary UDP and HTTP applications
communicate over two separate Linux TUN/pdn-net/pdn stacks and an AFSK1200 audio simulator. The
IP packets appear as AX.25 UI/PID 0xCC on both sides. With the channel paused the requests time
out; after it resumes they work again with fresh test IDs.

• Pinned Packet.NET/pdn-net sources and SDK 10.0.107.
• 13,295 Packet.NET tests passed, 48 skipped; 40 pdn-net baseline tests passed.
• The receive destination filter defect reproduced; 49 tests pass with the local patch.
• Eleven Python tests for audit guardrails, UDP retries and negative controls of the traces.
• Raw frames, routes, counters and test reports in the evidence package.

Start: bash scripts/setup-host.sh, then python3 scripts/test-two-nodes.py.

A simulator prerelease without bundled upstream binaries or container images. Hardware, Windows,
discovery, chat and mesh are not covered. The documents of this tag are in German.
