# reference-docs derivation (nix/reference-docs.nix, shipped into
# every agent container via claude --add-dir) builds from ../docs,

# Kept (build needs them): .nix, .rs, Cargo.*, branding/,
# frontend/, prompts/, flake.lock. docs/ is deliberately dropped:
# it is shipped to agent containers as its OWN narrow
# meta-flake input (`hyperhiveDocsSource`, below), threaded through
# hive-c0re → the meta flake → `hyperhive.docs.source`. Keeping docs/
# out of THIS source means a doc edit only re-hashes the docs input
# (a cheap re-link), not the whole flake source (which would rebuild
# every agent container). The old `nix/reference-docs.nix` build from
# `../docs` stays only for standalone `nix build .#reference-docs`
# from a full checkout — the meta path never evaluates it.
