- nix/checks.nix: 'hyperhive#3685' in a source comment trips the
tracker-tag lint (prose-only, per hive-rules.md) — argus caught it on
review. Reworded without the ref.
- frontend/npm-deps-hash: the earlier scaffold commit
(be18f460) added preact/typescript to agent/package.json, which
regenerated package-lock.json but never re-derived this hash in
lockstep — nix flake check's frontend derivation was failing on a
hash mismatch. Regenerated via
'nix run nixpkgs#prefetch-npm-deps -- frontend/package-lock.json'.
