Motivation

• Replace ad-hoc @seamapi/types-based parameter and response shapes with types derived from the @seamapi/blueprint so documented endpoints expose accurate parameter optionality, nullability, lists, nested objects and enums.
• Provide a single source of truth for resource response shapes to avoid duplicated, inconsistent resource declarations across generated routes.
• Preserve legacy @seamapi/types route types for undocumented endpoints and action-attempt responses where the blueprint cannot be used without breaking existing helpers.

Description

• Codegen now renders endpoint parameter types and shared resource types from the blueprint by extending codegen/lib/layouts/route.ts and codegen/lib/connect.ts and updating templates to conditionally use blueprint-derived types; undocumented endpoints and action-attempt responses keep @seamapi/types-based signatures.
• Introduced a generated src/lib/seam/connect/routes/blueprint-resources.ts that contains exported resource types (e.g., DeviceResource, AccessCodeResource, ActionAttemptResource, etc.) and updated route files to import and reference these types where appropriate.
• Updated codegen templates/partials to emit either RouteRequest/RouteResponse usage for legacy/undocumented cases or inline/declared blueprint-derived types for documented endpoints; added helpers (getResourceTypeName, renderBlueprintResources, object/enum renderers) to render TypeScript types from blueprint metadata.
• Regenerated the Connect route sources under src/lib/seam/connect/routes/... so many route signatures now reference blueprint-derived parameter and response types while retaining legacy types where needed.

Testing

• Ran generation with npm run generate and formatting/ESLint fixes as part of the pipeline, which completed successfully.
• Performed static checking with npm run typecheck (TypeScript tsc) and npm run lint, both of which passed after the generator updates and template fixes.
• Executed the test suite with an extended timeout using npx c8 ava --timeout=2m, which completed successfully; note that the default npm test run exceeded AVA’s default timeout, but the same suite passed with the explicit two-minute timeout.
• Verified code formatting checks (prettier --check) and generation output consistency during the postgenerate step (no formatting errors reported).
