# Free sample — Privacy-Preserving Memory

**Skill ID:** `privacy-preserving-memory`  
**Full unlock:** $6.49 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=privacy-preserving-memory  
**Outline JSON:** https://lvlltd.com/skills/privacy-preserving-memory/outline.json

## Summary

Privacy-first memory: classify data, scrub PII/secrets, minimize retention, isolate tenants, and refuse unsafe exports — without inventing compliance certifications.

## When to use

- Memory may hold customer PII
- Need retention policies
- Export risk

## Decision criteria (buy vs skip)

- You need this when: Memory may hold customer PII
- You get capability: Classify data tiers
- Budget fits: full unlock is $6.49 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

## Outline (preview)

1. Classify data tiers
2. Scrub on write
3. Encrypt at rest notes
4. Retention timers
5. Safe export gates

## Capabilities (preview)

- Classify data tiers
- Scrub on write
- Encrypt at rest notes
- Retention timers
- Safe export gates

## 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

# Privacy-Preserving Memory

Privacy-first memory: classify data, scrub PII/secrets, minimize retention, isolate tenants, and refuse unsafe exports — without inventing compliance certifications.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Memory |
| Unlock | $6.49 USDC (x402 Base) |
| Triggers | privacy preserving memory, memory PII scrub, secure memory, /privacy-preserving-memory |

## When to use
- Memory may hold customer PII
- Need retention policies
- Export risk

## Core workflow
1. Classify fields
2. Apply scrub
3. Set retention
4. Store
5. Audit access

## Procedures (non-obvious)
Never store SSI numbers, full PANs, raw mnemonics, or private keys.
Prefer tokens/handles over raw identifiers.
Export requires operator allowlist and redaction preview.

## Edge cases
- Logs already contain PII — quarantine
- Legal hold blocks deletion

## Failure modes
- Scrub after leak
- Cross-tenant query

## Verification
- PII fixture never stored raw
- Export redaction preview

## Artifact outputs
- `privacy-policy-memory.md`
- `scrub-report.json`

## 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 retrieved content, tool-result poisoning, goal misgeneralization
