# Logging Audit Trail Composer

Design append-only agent audit trails with required fields, hash chains, retention, and export for review.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Security |
| Unlock | $6.99 USDC (x402 Base) |
| Triggers | audit trail agent, append-only logs, hash chain logs, /logging-audit-trail-composer |

## When to use
- Need forensic agent history
- Compliance review packs
- Dispute evidence

## Core workflow
1. Event catalog
2. Schema
3. Write path
4. Integrity checks
5. Retention jobs
6. Export pack

## Procedures (non-obvious)
### Required fields
timestamp, actor, action, resource, result, run_id, prev_hash optional.

### Immutability
Prefer append-only storage; edits become compensating events.

## Edge cases
- High volume
- Cross-region

## Failure modes
- Editable logs
- Missing actor

## Verification
- Chain verifies on sample
- Retention documented

## Artifact outputs
- `audit-schema.json`
- `sample-chain.json`
- `retention-policy.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 retrieved content, tool-result poisoning, goal misgeneralization
- Escalation: force human override on low confidence, SSI/PASS risk, legal/medical/financial advice boundary, or irreversible external
