# Biomol External Non-AdK MD Evidence Gate — NhaA

## Status

PASS.

## Purpose

This gate validates MD Evidence against an external non-AdK trajectory path after protected result ownership, pilot keys, counters, quotas, and artifact protection were already operational.

## Dataset

- System: NhaA membrane protein
- Source class: public external MD trajectory
- Topology format: GRO
- Trajectory format: XTC
- Validation chunk: 20 frames
- Source atoms: 60,702
- Source residues: 1,314

## Protected workflow

The job was created through the protected website gateway using the internal validation pilot key.

The access registry registered the job and incremented the MD Evidence counter.

## Result

- Job ID: `stage2_20260502_090924_4r3swx6m`
- Result page: `https://protein.neoamorfic.ai/md-evidence/jobs/stage2_20260502_090924_4r3swx6m`
- Status: complete
- Completed files: 3
- Failed files: 0
- MD metrics computed: true
- Parse status: parsed

## Computed summary

| Metric | Value |
|---|---:|
| Frames | 20 |
| Atoms | 60,702 |
| Residues | 1,314 |
| Selection | protein |
| Selection atoms | 11,624 |
| Frames analyzed | 20 |
| RMSD mean Å | 2.759966 |
| RMSF mean Å | 2.064565 |
| Radius of gyration mean Å | 31.295446 |

## Errors and warnings

- Errors: none
- Warnings: none

## Counter update

After this gate:

- Total registered jobs: 3
- MD Evidence jobs: 2
- Structural Triage jobs: 1
- Internal validation key jobs used: 3 / 20
- MD Evidence upload bytes used: 29,656,921

## Interpretation

This confirms that MD Evidence is not limited to the earlier AdK validation path. It can process a protected, counted, external non-AdK GRO+XTC trajectory package and generate a protected evidence result with descriptive MD summaries and downloadable artifacts.

## Scope

This gate validates file handling, protected job creation, parsing, descriptive metric computation, and evidence packaging. Scientific interpretation of the trajectory remains the responsibility of expert review.
