Operating context
Financial code changes must satisfy functional, security, privacy, supervisory, and resilience requirements. Repeated full reviews by every stakeholder create long lead times.
The objective is not to remove review, but to structure the evidence so each accountable owner can focus on the controls they own.
Deployment design
Patty Code uses repository rules and prior incident or audit patterns to propose implementation and tests together. Payment, identity, and entitlement modules can be excluded from autonomous execution.
PCCP separates developer and approver roles and applies distinct approval chains to merge and deployment. External packages, production data, and infrastructure changes require separate policy decisions.
Operating flow
- 01
Requirements are decomposed into changed files and validation items. Security reviews data and entitlement changes while the service owner reviews functional impact and rollback.
- 02
Every approved tool call is recorded with its policy decision. Repository checks, security scans, tests, and deployment approval share one execution ID.
- 03
Auditors can follow one record from requirement to release instead of manually reconciling logs from separate systems.
Pre-deployment validation
- Separation of duties applied to both merge and deployment
- Disallowed calls and data access were blocked before execution
- Requirements and tests remained linked to one change unit
- Rollback conditions and owners were declared before release
