Third-party material
Every line in this repo that came from someone else is listed here, with the upstream file and the commit it was read at. An empty section is a claim: it says we looked and took nothing, and it is as much a statement as a filled one.
The rule that makes this file worth keeping: a port is added here in the same commit that adds the ported code, never afterwards. A retroactive attribution sweep cannot be verified by anyone, including us.

What we take, and how: a dependency, not a port. Every crate in that workspace publishes to crates.io under the same licence, so the wire model is imported rather than transcribed:
ts_control_serde 0.5.0— thetailcfgwire model (MapResponse,Node,DerpMap,RegisterRequest/Response). Used bycrates/tunnr-tailscale/src/netmap.rs.- transitively,
ts_keys,ts_capabilityversion,ts_hexdump,ts_nodecapability,ts_peercapability,ts_packetfilter_serde.
Depending on it rather than reimplementing it is deliberate: their coordination protocol is a version-coupled contract documented mostly by that source, so a hand-written parser would be a second definition of it that drifts silently.

What we deliberately do NOT take, measured 2026-09-05 with
cargo tree -e normalover a resolved crates.io closure:ts_transport(and sots_derp,ts_control) — depends unconditionally ondyn-eq 0.1.3, MPL-2.0. No feature gate removes it. This workspace takes no copyleft of any strength, andcrates/tunnr-licenceenforces that on every build.ts_tls_util(and sots_control,ts_derp,ts_http_util) — hardcodestokio-rustls { default-features = false, features = ["aws-lc-rs"] }, draggingaws-lc-sys(a BoringSSL fork built with cmake + cc) in. Not selectable.

Vendored test data, BSD-3-Clause, same commit:
crates/tunnr-tailscale/tests/fixtures/map_response.json— verbatim fromts_control_serde/tests/data/map_response.jsoncrates/tunnr-tailscale/tests/fixtures/node.json— verbatim fromts_control_serde/tests/data/node.json
These are real documents recorded from Tailscale's coordination server. We hold no auth key for any tailnet, so they are the only captured bytes this lane could assert against, and every test that uses them is named captured_* so it never reads as a live proof.
BSD-3-Clause requires the copyright notice and the disclaimer be retained. Nothing in this repository is a copy of their source — the crates are linked from crates.io and the two JSON files are data — so the notice lives here and in the module docs rather than in a file header we would have had to invent.
No endorsement is implied and none exists. "Tailscale" is Tailscale Inc.'s trademark; this crate is compatible with their protocol and is not a Tailscale client.
