Summary

This branch adds the ./nix/pikaci directory to the Nix flake's Rust source inputs so that pikaci nix fragments are included in the Rust build's source-filtering logic. Without this change, files under nix/pikaci were invisible to the Nix build, meaning any Rust code that referenced or embedded those fragments at build time would fail or produce stale results. The fix is a single-line addition duplicated across the two source-filter lists in flake.nix.

Tutorial Steps

Add `./nix/pikaci` to the first Rust source filter list

Intent: Ensure the first source-filtering block in `flake.nix` (used by one of the Nix build expressions) includes the `nix/pikaci` directory so its contents are available during the Rust build.

Affected files: flake.nix

Nix flakes use explicit source-filter lists to decide which paths are copied into the build sandbox. The first list (around line 83) enumerates every directory the Rust workspace needs.

By adding ./nix/pikaci between ./fixtures and ./pikachat-openclaw/…, the pikaci nix fragments are now part of the filtered source tree. This keeps the list in alphabetical order, consistent with the surrounding entries.

  ./config
  ./crates
  ./fixtures
+ ./nix/pikaci

Add `./nix/pikaci` to the second Rust source filter list

Intent: Mirror the same inclusion in the second source-filter block (around line 100) so that both derivations that consume Rust sources have access to the pikaci nix fragments.

flake.nix contains two parallel source-filter lists — one per build variant or derivation that compiles the Rust workspace. Both must stay in sync; omitting the path from either list would cause that particular build to lack the pikaci fragments.

The identical one-line addition is applied here:

  ./config
  ./crates
  ./fixtures
+ ./nix/pikaci
  ./pikachat-openclaw/openclaw/extensions/pikachat-openclaw

After this change, running nix build (or any CI job that evaluates the flake) will copy nix/pikaci/** into the sandbox for both derivations, allowing Rust include_bytes!, include_str!, or build-script logic to reference those files successfully.
