`nix develop` now yields the toolchain the repository actually needs — Node, `git`, `tea`, and `curl` — giving a declarative answer to "what do I need to work on this", which the repository previously specified nowhere. The shell takes its Node from the package's `passthru` rather than naming `pkgs.nodejs` a second time, so development and the shipped artifact cannot drift onto different majors and cannot be set independently. `package.nix` declares that `passthru` as an interface rather than leaving the shell to read an incidental build attribute; it does not enter the derivation, so the store path is unchanged. The checks output aliases the package, so `nix flake check` builds it and thereby runs both its verification phases instead of being a silent no-op. No per-stage checks: the only stage adding coverage is the full typecheck, which spans `test/` and `bench/` and would drag the benchmark harness into the derivation's inputs, undoing the source filtering. It stays in CI. The shell deliberately omits `gitea-axi` itself. The benchmark's arm resolves that binary by name off PATH and must get the locally built `dist/main.js`, so supplying the packaged one would silently substitute the wrong artifact.
