# Voice Scribe — CrispASR runtime, macOS arm64

Pre-built CrispASR runtime for the Voice Scribe Apple Silicon stack. Mirror of
[`CrispStrobe/CrispASR`](https://github.com/CrispStrobe/CrispASR.git) `v0.6.0`
(commit `a471a3c6f93a69dd2f13b9b828312aa9bf99ebd7`) built with Metal + CPU GGML
backends, for use as the `crispasr` binary backing the `parakeet-tdt-0.6b-v3`
GGUF Q5 lane on macOS.

This is a **runtime bundle**, not a model. Voice Scribe downloads it on first
run when the user picks Parakeet in Settings → ASR (or first PTT after
selection). Layout:

```
bin/crispasr                           1.9 MB  arm64 binary
lib/libcrispasr.0.6.0.dylib            3.0 MB  primary runtime
lib/libggml-base.0.10.2.dylib          0.7 MB  GGML core
lib/libggml-cpu.0.10.2.dylib           0.8 MB  GGML CPU backend
lib/libggml-metal.0.10.2.dylib         ?  MB  GGML Metal backend
lib/libggml.0.10.2.dylib               ?  MB  GGML facade
manifest.json                                   sha256 + size per file
```

(Symlinks `lib*.dylib`, `lib*.0.dylib`, `lib*.1.dylib` rebuild client-side from
the canonical files via `parakeet/scripts/download_models_apple.py --runtime
crispasr`.)

## Provenance

| Field | Value |
| --- | --- |
| Upstream repo | `https://github.com/CrispStrobe/CrispASR.git` |
| Upstream ref | `v0.6.0` |
| Upstream commit | `a471a3c6f93a69dd2f13b9b828312aa9bf99ebd7` |
| Build host macOS | (see `manifest.json`) |
| Target arch | `arm64` |
| GGML backends | Metal + CPU (BLAS off) |
| Compatibility | macOS 13.0 + Apple Silicon |
| Signing | ad-hoc (Developer ID + notarization land via `release.yml`) |

Authoritative file hashes are in `manifest.json`. Voice Scribe verifies sha256
of every downloaded file against the manifest at first-run install time.

## Verification

```bash
shasum -a 256 bin/crispasr lib/*.0.6.0.dylib lib/*.0.10.2.dylib
```

Expected hashes match the `files[].sha256` entries in `manifest.json`.

## Smoke test

```bash
DYLD_FALLBACK_LIBRARY_PATH=/path/to/lib bin/crispasr --version
```

Should print:

```
=== build info ===
  version       : 0.6.0
  git sha       : a471a3c6
```
