# Local Parakeet ASR evidence

Date: 2026-06-07

This note separates local Parakeet ASR artifact availability from a real local ASR proof. Artifact availability is not proof that the app has used Parakeet audio or that the local/off-grid audio path is ready.

## Artifact status

- Model repo: `nvidia/parakeet-rnnt-1.1b`
- Revision: `a07b19e98a26c1873a3f2622c446a4a1ca6316cb`
- Local snapshot path: `/Users/drake.thomsen/.cache/huggingface/hub/models--nvidia--parakeet-rnnt-1.1b/snapshots/a07b19e98a26c1873a3f2622c446a4a1ca6316cb`
- Local artifact: `parakeet-rnnt-1.1b.nemo`
- Artifact size: `4283105280` bytes
- Artifact SHA-256: `535896f014953d945b287ac533560e20da8103c6781b152de4645528e2b60738`

## Evidence helper

Use the helper to capture local ASR evidence:

```bash
PYTHON_DOTENV_DISABLED=true \
python3 scripts/run_local_asr_evidence.py \
  --audio <source-audio.wav> \
  --transcribe-audio \
  --provider-note "<device/runtime command>"
```

If a provider payload was captured by a separate local runtime, pass it directly:

```bash
PYTHON_DOTENV_DISABLED=true \
python3 scripts/run_local_asr_evidence.py \
  --provider-payload <local-parakeet-provider-output.json> \
  --audio <optional-source-audio.wav> \
  --provider-note "<device/runtime command>"
```

The helper writes a timestamped evidence directory under `traces/local_asr_parakeet_evidence_*`:

- `artifact_metadata.json`: Parakeet `.nemo` presence, size, and hash
- `audio_metadata.json`: optional source-audio metadata and hash only; raw audio is not copied into the evidence bundle
- `provider_payload.json`: provider output generated by `--transcribe-audio`, when that path is used
- `provider_payload_metadata.json`: provider output file hash
- `audio_draft.json`: Figment draft generated from the provider payload under `AUDIO_BACKEND=parakeet_nemo` and `ALLOW_LOCAL_ASR=true`
- `draft_checks.json`: evidence-gated checks for Parakeet provenance, confirmation status, and raw-audio handling
- `asr_evidence_manifest.json`: compact manifest with artifact status, provider-payload hash, configured route, draft summary, raw-audio handling, and proof flags
- `summary.json`: top-level proof flags

Exit codes are evidence-gated:

- `0`: provider payload passed all local ASR draft checks
- `2`: artifact exists but provider payload is missing or not proof
- `1`: artifact missing

## Current result

The artifact-only helper run succeeded in finding the Parakeet `.nemo` file but exited `2` because no real local ASR provider payload was supplied:

```text
status=artifact_present_provider_payload_required
counts_as_local_asr_artifact=true
counts_as_local_asr_proof=false
raw_audio_stored=false
asr_evidence_manifest_path=/tmp/figment-local-asr-artifact-only-manifest-check/asr_evidence_manifest.json
```

This means artifact presence alone remains insufficient. The app now has a Parakeet ASR adapter path; the proof upgrades only after a real audio run produces a provider payload and the helper records `counts_as_local_asr_proof=true`.
