# subtext

Rust FSKit backend with a toy reverse filesystem (`src/reverse.rs`): files are stored bytewise-reversed on disk, but read normally.

The active backend is picked at compile time (`src/backend/`):

- default → real FSKit mount via `fskit_rs::mount`.
- `--features dev` → socket-only daemon on `127.0.0.1:$SUBTEXT_DEV_PORT` (default `8080`); no FSKit, no `mount(8)`.

**Prereqs:** stable Rust, `protoc` on `PATH` (e.g. `brew install protobuf`).

```sh
cargo run --features dev                  # start the daemon
cargo run --bin fsclient -- smoke         # end-to-end round-trip
cargo run --bin fsclient -- put a.txt --content hi
cargo run --bin fsclient -- ls
cargo run --bin fsclient -- cat a.txt
```

`fskit-rs` is vendored in `vendor/fskit-rs` (changelog there if you re-bootstrap from the registry).
