 ## Notes
 
-> To be filled by implementation agent
+All schemas follow the TypeBox-as-single-source-of-truth pattern. WorkflowCostTaskEntry is an internal schema (not exported) used within WorkflowCostResult's tasks array. EvConfig fields use `Type.Number({ default: 0 })` per architecture spec for defaults. The `WorkflowCostOptions.propagationMode` is correctly a `Type.Union` of two `Type.Literal` values as specified. Results.js was already re-exported from index.ts.
 
 ## Summary
 
-> To be filled on completion
+Implemented all 7 analysis result TypeBox schemas with `Static<typeof>` type aliases.
+- Created: `src/schema/results.ts` (7 schema constants + 7 type aliases + 1 internal WorkflowCostTaskEntry)
+- Modified: `test/schema.test.ts` (46 new tests: 39 runtime validation + 7 compile-time type alias verification)
+- Tests: 137 total, all passing; `tsc --noEmit` clean
