# Loko Release Gate Records

Public, third-party anchored **Release Gate** decision artifacts for pinned vision model revisions.

This repository publishes two runs that demonstrate the difference between:
- **Run A (Baseline Repro):** reproducible benchmark surface on COCO
- **Run B (Production Gate):** class-scoped operational gating under low-light conditions

This is not a benchmark leaderboard claim. It is an audit-friendly release record pattern.

> Note: Hugging Face’s Dataset Viewer may show a warning because this repo is an artifact record store (reports, manifests, receipts), not a dataset split intended for browsing.

## What a “Release Gate Record” contains

Each run includes:
- Pinned **model repo + exact commit revision**
- Pinned **dataset repo + exact commit revision**
- Declared **release predicate** (the gate)
- Deterministic **PASS/FAIL** container (certificate)
- Metrics JSON (filled when the run is executed)
- Offline HTML report + receipt bundle
- Checkout manifest + signature
- Full folder manifest (hash index)

---

## Runs

### Run A — Baseline Repro (COCO)

**Goal:** Bind a release decision to pinned, reproducible inputs on a benchmark surface.

- Model: `Ultralytics/YOLOv5` @ `553ca28641b8c2129596b0ecc50fc0902f7bd7ac` (`yolov5s.pt`)
- Dataset: `rafaelpadilla/coco2017` @ `7d5136d6952da2df12d99106e2cce2a65324617d` (split: `validation`)
- Gate: `coco_baseline_map50_floor_v1` (mAP@0.50 >= 0.36)

Artifacts:
- Report: [run-a-baseline-repro/report.html](run-a-baseline-repro/report.html)
- Certificate: [run-a-baseline-repro/release_certificate.json](run-a-baseline-repro/release_certificate.json)
- Metrics: [run-a-baseline-repro/evaluation_metrics.json](run-a-baseline-repro/evaluation_metrics.json)
- Checkout manifest: [run-a-baseline-repro/checkout_manifest.json](run-a-baseline-repro/checkout_manifest.json)
- Signature: [run-a-baseline-repro/checkout_manifest.sig](run-a-baseline-repro/checkout_manifest.sig)
- Full hash index: [run-a-baseline-repro/loko_manifest.json](run-a-baseline-repro/loko_manifest.json)

---

### Run B — Production Gate (Low-Light, class-scoped)

**Goal:** Demonstrate production-style gating: PASS/FAIL is defined by operational predicates, not benchmark bragging.

- Model: `Ultralytics/YOLOv5` @ `553ca28641b8c2129596b0ecc50fc0902f7bd7ac` (`yolov5s.pt`)
- Dataset: `SatwikKambham/ex-dark` @ `f2a15374dae8c90395f461c5ba0546c034751665`
- Scope: class-scoped to `person`
- Gate: `exdark_person_operational_gate_v2_strict` at confidence 0.5  
  - precision >= 0.85  
  - recall >= 0.80  

Artifacts:
- Report: [run-b-production-gate/report.html](run-b-production-gate/report.html)
- Certificate: [run-b-production-gate/release_certificate.json](run-b-production-gate/release_certificate.json)
- Metrics: [run-b-production-gate/evaluation_metrics.json](run-b-production-gate/evaluation_metrics.json)
- Checkout manifest: [run-b-production-gate/checkout_manifest.json](run-b-production-gate/checkout_manifest.json)
- Signature: [run-b-production-gate/checkout_manifest.sig](run-b-production-gate/checkout_manifest.sig)
- Full hash index: [run-b-production-gate/loko_manifest.json](run-b-production-gate/loko_manifest.json)

## Quick verify in 30 seconds

1) Open the **certificate** and confirm the decision:
- Run A: PASS  
- Run B: FAIL  

2) Confirm the **receipt bundle** is fully indexed:
- `checkout_manifest.json` lists `receipt_bundle/**` with sha256 + sizes

3) Confirm the folder is fully indexed:
- `loko_manifest.json` lists the full run folder (including the manifest + signature files) with sha256 + sizes

4) Confirm the signer identity is pinned:
- `PUBKEY_PIN.txt` contains the pinned pubkey hash
- `operator_ed25519_public.pem` provides the demo public key used for signing

## Offline package (ZIP + .loko payload)

This repo also publishes a single Windows zip that contains:
- the two `.loko` payloads (Run A + Run B)
- their `.loko.sha256` receipts
- a lightweight verifier script
- `sha256.txt` for the zip contents
- `RUNME.txt`

Download:
- `ReleaseGate_win.zip`
- `ReleaseGate_win.zip.sha256`

### Windows (PowerShell)

```powershell
Expand-Archive .\ReleaseGate_win.zip -DestinationPath .\ReleaseGate -Force

# Verify Run A
python .\ReleaseGate\bin\verify_release_gate_loko.py --loko .\ReleaseGate\incoming\run-a-baseline-repro.loko --out .\REVIEW_run_a --pubkey-pin 1f61014bc8bf5bedc9389c5950d9a46c703c8d91701d762b892fd1a924dcd367

# Verify Run B
python .\ReleaseGate\bin\verify_release_gate_loko.py --loko .\ReleaseGate\incoming\run-b-production-gate.loko --out .\REVIEW_run_b --pubkey-pin 1f61014bc8bf5bedc9389c5950d9a46c703c8d91701d762b892fd1a924dcd367
```

Verification performs:
- `.loko.sha256` validation
- Safe extraction
- Pinned signer identity check (pubkey pin)
- `checkout_manifest.sig` signature validation
- `loko_manifest.json` file index verification (sha256 + size)

Expected result:
- Run A → PASS
- Run B → FAIL (strict operational gate not satisfied)
