Seam verification validates producer and consumer contracts to ensure data crossing API, UI, or internal boundaries remains consistent. You need it after making multi-file changes to confirm integration points are intact and prevent broken data flow.

You find integration seams by using HelixDB to locate data producers and consumers across boundaries, then applying Repo Prompt to inspect contracts and usages. This process identifies where data crosses API, UI, and internal function call boundaries.

You check for contract mismatches by comparing producer and consumer definitions using Repo Prompt to inspect usages. This surfaces inconsistencies and optionality issues between modified files and their downstream consumers across API and UI boundaries.

Yes, seam verification works with HelixDB and Repo Prompt for static analysis. HelixDB locates producers and consumers across boundaries, while Repo Prompt inspects contracts and usages to flag mismatches and generate a remediation-ready verification report.

The best way to generate a seam verification report is by running the seam verification workflow after finishing a multi-file change. It extracts producer and consumer contracts, compares definitions, flags mismatches, and produces actionable remediation fixes.

Multi-file changes break integration points when producer and consumer contracts have mismatches or optionality issues that standard tests miss. Seam verification extracts and compares these contracts across boundaries to surface hidden data flow inconsistencies.
