# Harden code security
## Contract
| Field | Bound contract |
|---|---|
| Trigger | Handling untrusted input, auth/authz, data storage, external integrations, files/uploads/payment. |
| Authority | Reversible local: writes only security controls added to code during construction, plus a verification report beside those controls; rollback is version control. No remote mutation. |
| Side effect | Local-write: changes to code files plus a verification report; no credential, deployment, or remote mutation. |
| Done | Security-relevant code passes the always-do checks and verification checklist. |
## Not for
- Auditing a diff or change set for vulnerabilities: use security-review.
