📝 Changes Description

This PR defines the domain model and TypeScript types for the "credit credential" in the credit-history product, unblocking the subsequent UI and mock issues.

Specifically, it adds:

• CreditCategory: Union of credential categories with comments (INCOME, EMPLOYMENT, etc.).
• CreditStatus: Explicit app-level status representing valid, revoked (with date), and invalid.
• CreditCredential: The main app-level interface independent of the @acta-team/credentials SDK.
• CreditProfileSummary: Interface for the summary view tracking totals and status counts.

Location Decision:
The types were intentionally placed in apps/credit-history/src/types/index.ts instead of @acta-products/types. This is because these types are strictly specific to the credit-history product, whereas @acta-products/types is intended to remain cross-product and free of product-specific domains.

🌌 Comments

Code compiles successfully with pnpm lint, pnpm typecheck, and pnpm build at the app level. No visible UI strings added, pure domain models.

📝 Walkthrough

Walkthrough

A new barrel file apps/credit-history/src/types/index.ts is created with 40 lines, adding four exported TypeScript types: CreditCategory (union of five credential categories), CreditStatus (discriminated union of valid, revoked, and invalid app-level states), CreditCredential (core credential interface), and CreditProfileSummary (aggregated counts and totals interface).

Summary

Credit domain type declarations apps/credit-history/src/types/index.ts

Adds CreditCategory (five-member string union), CreditStatus (discriminated union with optional revokedAt on the revoked variant), CreditCredential (core credential shape with id, category, issuerName, issuerDid, issuedAt, status, and loosely typed claims), and CreditProfileSummary (per-category totals, valid/revoked/invalid counts, and oldestIssuedAt). No external SDK dependencies are introduced.

Poem

🐇 A barrel of types, fresh and new,
CreditCategory — five paths to construe,
valid, revoked, invalid in a row,
The credential shape all set to glow,
No SDK chains, just pure domain dew! ✨
