Stand up document retrieval as shared, client-agnostic primitives rather
than locking it inside Open WebUI:
- Qdrant as the LAN-reachable vector store
- LiteLLM gains a bge-m3 route so sgx:4000 also serves /v1/embeddings
- a thin `rag` CLI (ingest/query, optional coder synthesis) usable from
any machine and from scripts
Embeddings and synthesis run on halo via the gateway; the CLI is
configured entirely through RAG_* env vars.
Vendors the npm tarball + lockfile and wraps the `pi` binary with `fd` and
`ripgrep` on PATH. Also installs it on the m4 darwin host.
`buildNpmPackage` is pulled from `inputs.unstable` because nixos-25.11's
`prefetch-npm-deps-0.1.0` panics on cacache index entries that contain
either multiple lines or JSON values with embedded spaces (npm's
`accept: application/...; q=1.0, ...` headers). For this lockfile,
`@esbuild/netbsd-arm64` and `@rollup/rollup-linux-x64-musl` trigger
both conditions and `--map-cache` fails with `EOF while parsing a
string at line 1 column 369`. Fixed upstream in nixos-unstable, which
now uses `lines()` + `split_once('\t')`.
- Replaced `host.pkgs.system` with `host.pkgs.stdenv.hostPlatform.system` in `default.nix` for consistent attribute referencing.
- Aligns with recent changes in Nixpkgs attribute structure and improves compatibility.
Replaces `[[ $# > 0 ]]` with `(( $# > 0 ))` for clarity and correctness. This ensures improved readability and adherence to best practices in Bash scripting.
This commit adds support for the Brother DCP-L2530DW printer driver. The new file, dcpl2530dw-cups/default.nix, includes necessary build inputs and sets up installation paths. Currently, this build only supports the x86_64 platform.
