The bump itself is fine, and the "4 → 7" jump is smaller than it looks: on main, actions/checkout@v7 is already at seven call sites and v4 survived only at ci.yml:152, the STANDARD.md matches upstream job — added with v4 hardcoded while the rest of the file had moved. This is the last straggler coming into line on a version this repo's CI already runs. (Same straggler, same cause, as serialize.go#12 earlier today.)

I checked the one v7.0.0 behavior change that could actually bite — it refuses to check out fork PRs under pull_request_target / workflow_run. ci.yml uses neither event, and cla.yml does use pull_request_target but never checks anything out. No exposure.

The red check is not this PR. VersionFull matches upstream is failing identically on main (bb28672), so it arrived before the bump and the bump cannot have caused it — nothing in a checkout version reaches that job.

Its cause, verified against the source rather than inferred: upstream cut v1.4.2 at 2026-07-26T00:00:28Z and netcode.h now says NETCODE_VERSION_FULL "1.4.2", while netcode.go:45 still says 1.4.0. The drift check is doing exactly the job it was written for.

What the two intervening releases imply here, as far as I can see from the release notes and this tree:

• 1.4.1 is spec-only — netcode.c/netcode.h byte-identical to 1.4.0, the change being STANDARD.md scoping the nonce guarantee to a server run plus optional restart mitigations. This repo's vendored STANDARD.md already matches upstream (that check is green), and the restart nonce fix is ported and pinned here already — restart_test.go, and the retract block in go.mod.
• 1.4.2 is the vendored libsodium 1.0.21/1.0.22 hardenings in the C tree's sodium/ subset. This port has no vendored crypto — it's golang.org/x/crypto — so there is no direct analogue to carry across.

So this looks like a version-constant bump (VersionFull and VersionPatch at netcode.go:45,48) rather than a port of behavior — but the job's own instructions say read what changed and port whatever it implies, and that read is the maintainer's, not mine. Flagging it rather than making it, since it's a separate change from this PR.

Not merging: netcode.go is one of the flagship ports, so it goes to Glenn even when the diff is one line and the rest of CI is green.
