vertical-slice-contract-repair

Fix contract drift by aligning cross-layer contracts and placeholder mappings across desktop host, service, and frontend layers, enforcing canonical vocabularies and removing duplicate DTOs during integration recovery.

Order integration placeholders by dependency using a host seam to service call to UI action to result rendering sequence, which orchestrates vertical slice repair and ensures a runnable solution entry point.

Yes, you can deduplicate DTOs when domain shapes already match bridge payloads, removing duplicate transport objects to standardize message types and harmonize cross-layer contracts before UI polish.

Define explicit failure boundaries for integration reviews by gating reviewers with stable failure codes such as empty-run or invalid-input, bounding failure modes to stabilize cross-layer contract alignment.

Promote skipped tests into real tests during a refactor once a host seam exists, uplifting test coverage to validate dependency-ordered placeholder mappings across the vertical slice.

Yes, vertical slice contract repair requires a runnable solution entry point to ensure all real projects and tests are included, validating that host, service, and frontend contracts are harmonized.
