Sprint 98 Plan: Multimodal Evidence and Artifact Verification

Context

Some migrations involve diagrams, protocol specs, and non-code artifacts. Sprint 98 extends verification to multimodal evidence.

---

Goals

1. Normalize non-code artifacts into verification evidence model
2. Link multimodal artifacts to semantic claims and risks
3. Improve confidence for architecture-level migrations
4. Prevent evidence gaps caused by code-only evaluation

Steps

Step 1209: Multimodal evidence schema extension (12 tests)

Step 1210: Diagram/spec artifact ingestion adapters (10 tests)

Step 1211: Architecture claim linkage engine (10 tests)

Step 1212: Cross-artifact consistency checker (10 tests)

Step 1213: Multimodal evidence completeness scoring model (10 tests)

Step 1214: Verification gate integration for architecture artifacts (8 tests)

Step 1215: whetstone_attach_multimodal_evidence MCP tool (8 tests)

Step 1216: whetstone_verify_architecture_consistency MCP tool (8 tests)

Step 1217: Multimodal verification dossier template (8 tests)

Step 1218: Sprint 98 integration summary + regression (8 tests)

Evidence Rule

• High-level architecture claims must include linked supporting artifacts.
