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
• Certificate: run-a-baseline-repro/release_certificate.json
• Metrics: run-a-baseline-repro/evaluation_metrics.json
• Checkout manifest: run-a-baseline-repro/checkout_manifest.json
• Signature: run-a-baseline-repro/checkout_manifest.sig
• Full hash index: 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
• Certificate: run-b-production-gate/release_certificate.json
• Metrics: run-b-production-gate/evaluation_metrics.json
• Checkout manifest: run-b-production-gate/checkout_manifest.json
• Signature: run-b-production-gate/checkout_manifest.sig
• Full hash index: 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)

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)
