# Form Filling Protocol

Reliable form automation protocol: field mapping, validation recovery, multi-step wizards, file uploads, and never logging full payment numbers.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Browser |
| Unlock | $5.99 USDC (x402 Base) |
| Triggers | form filling protocol, automate form, browser form agent, /form-filling-protocol |

## When to use
- Multi-step signups
- Repetitive admin forms
- QA data seeding via UI

## Core workflow
1. Discover fields
2. Build map
3. Fill in order
4. Resolve validation
5. Assert success

## Procedures (non-obvious)
Prefer getByLabel / getByRole. Payments use test tokens only; never log card numbers.
Multi-page checkpoint after each page. OTP steps escalate to human.

## Edge cases
- Custom dropdowns
- Shadow DOM
- OTP human handoff

## Failure modes
- Invalid submit loops
- Logging PII

## Verification
- Success selector visible
- No PII in logs

## Artifact outputs
- `field-map.json`
- `fill-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 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 s
