npm `playwright` is pinned to the flake's `PLAYWRIGHT_VERSION`. `just freshness` fails when that pin drifts or a lock file is committed. Bump the toolchain with `nix flake update` and the pin together.

P1 Badge Keep published MoQ packages on latest

Every rust-legacy run defaults to installing moq-token-cli 0.5.38, but this repository explicitly requires MoQ packages to remain on latest and identifies Playwright as the sole version pin. This compatibility-floor cell therefore changes the repository's testing contract and makes a historical artifact gate CI; remove the pin or obtain an explicit policy change before adding this lane.

Require a current-format subtree token before testing exact-pattern rejection.

The subtree setup signs with rust-legacy. It proves only that the legacy verifier accepts its own format. If the legacy verifier rejects all current-format tokens, the exact-pattern check still prints PASS for a format failure rather than an exact-pattern rejection. The reported cross-format failure makes this case concrete. Sign a subtree token with exact_gen and require rust-legacy to accept it before testing the exact token.

In `@token.sh` at line 466, Update the subtree setup around `sign rust-legacy` to
generate the subtree token with `exact_gen`, then require `rust-legacy` to
accept that token before testing exact-pattern rejection.
