# Named, explicitly-filtered source views of this repo. Each real

# Filtered view of this repo handed to hive-c0re as the `hyperhive`
# meta-flake input. Drops files no nix or cargo derivation reads —
# shell helper scripts and root-level markdown — so editing them
# does NOT change the store path and therefore does NOT force a
# rebuild of every agent container.
#
# Dropped: scripts/, docs/, root-level *.md (README/CLAUDE/TODO/…).
# 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 `reference-docs` build from `../docs`
# stays only for standalone `nix build .#reference-docs` from a
# full checkout — the meta path never evaluates it.

# here on the host where docs/ exists — it cannot be derived from
