Cross-Platform Contract Propagation Audit

Overview

Audit a contract change from its source through every transformation and consumer before release. Treat a field that exists in one schema as incomplete until its meaning, defaults, wire behavior, rollout controls, client handling, analytics, and tests are proven across all relevant paths.

This is a read-only evidence workflow. It reports propagation gaps; it does not implement them.

When to Use This Skill

• Use when adding or changing a field, enum value, status, capability, or feature flag shared by multiple components.
• Use when database, backend, API, Web, Android, iOS, jobs, events, or analytics may interpret the same value differently.
• Use when a change must preserve existing records, older clients, or a default-off rollout.
• Use when a change looks complete in one endpoint but may be missing from alternate entry points or generated models.
