# Free sample — Neuro Signal Processing

**Skill ID:** `neuro-signal-processing`  
**Full unlock:** $8.49 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=neuro-signal-processing  
**Outline JSON:** https://lvlltd.com/skills/neuro-signal-processing/outline.json

## Summary

Build reproducible neuro/biosignal processing pipelines: filtering, artifact handling, feature extraction, and audit logs — research tooling only.

## When to use

- EEG/EMG research pipelines
- Need artifact strategy
- Reproducible feature extraction

## Decision criteria (buy vs skip)

- You need this when: EEG/EMG research pipelines
- You get capability: Define sampling and montage notes
- Budget fits: full unlock is $8.49 USDC on Base
- You can automate unlock via HTTP 402 without a browser
- You only need teaser/outline first — sealed src/ops stay locked until payment

1. Define sampling and montage notes
2. Filter plan
3. Artifact rules
4. Features
5. Export and provenance

## Capabilities (preview)

- Define sampling and montage notes
- Filter plan
- Artifact rules
- Features
- Export and provenance

## What you get after payment

- SKILL.md (teaser public)
- agent-install.json (public meta)
- src/index.js (stub public; full after unlock)
- Full sealed: src/, schemas/, ops/* (when present) after verified X-PAYMENT

# Neuro Signal Processing

Build reproducible neuro/biosignal processing pipelines: filtering, artifact handling, feature extraction, and audit logs — research tooling only.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Neurotech |
| Unlock | $8.49 USDC (x402 Base) |
| Triggers | neuro signal processing, EEG pipeline, biosignal features, /neuro-signal-processing |

## When to use
- EEG/EMG research pipelines
- Need artifact strategy
- Reproducible feature extraction

## Core workflow
1. Ingest raw with metadata
2. QC and artifact labels
3. Filter and epoch
4. Extract features
5. Validate reproducibility
6. Export with provenance

## Procedures (non-obvious)
### Reproducibility
Pin library versions; store random seeds; never silently drop channels without QC log.

### Not clinical
Outputs are research features, not diagnostic scores.

## Edge cases
- Motion-heavy ambulatory data
- Missing impedance logs

## Failure modes
- Silent channel drop
- Overfitting features as diagnosis

## Verification
- QC log present
- Pipeline params pinned
- Disclaimer present

## Artifact outputs
- `pipeline.md`
- `params.json`
- `qc-report.md`

## Super Alignment Contract
- Scalable oversight method: process supervision + human+AI critique before high-blast actions
- Corrigibility guarantees: shutdown, steerability, non-deception; operator may abort mid-run
- Value model: Partnership Agreement + 5 Behavioral Protocols
- Drift detection: flag invented evidence, skipped verification, or revenue-over-truth optimization
- Red-team surface: prompt injection via retrie
