feat(epc): EPC integration foundation by chrismaz11 · Pull Request #150 · TrustSignal-dev/TrustSignal

chrismaz11 · 2026-05-11T00:07:16Z

Builds the complete EPC integration skeleton: OAuth2 client with token caching, 5 Prisma models for transaction lifecycle, origin request endpoint, Elli-Signature webhook receiver, AES-256-GCM per-lender credential storage, and product registration documentation. All 19 tests passing. All sandbox-dependent behavior marked with TODO comments. Additive only — zero changes to existing production routes or auth.

…igin endpoint, webhook receiver, credential storage, 19/19 tests passing

Pull request overview

Builds the initial EPC (eMortgage Partner Consortium) integration scaffolding in the API (feature-flagged routes, webhook verification, credential encryption, and Prisma models), adds EPC-focused unit tests + documentation, and tightens several workflows and tests.

Changes:

Adds EPC modules (auth, origin, webhook, credentials), new EPC Prisma models + migration, and EPC product registration documentation.
Wires EPC routes into apps/api/src/server.ts behind EPC_ENABLED, and adds/updates multiple test suites (EPC unit tests + API E2E tweaks).
Updates CI/workflows (pinned actions + reduced permissions) and repo-consistency tooling behavior.

.github/workflows/ci.yml:16

The CI workflow no longer runs the existing npm run test:skip-policy check (scripts/enforce-skip-policy.mjs). That policy currently guards against accidental .skip usage in tests; removing it makes it easy for skipped tests to land unnoticed. Consider re-adding a lightweight job/step to enforce the skip policy.
