Overview

This PR adds an OpenAPI 3.1 spec generated from the existing Zod request schemas, serves it at /openapi.json in non-production, and adds a CI drift check that fails when the committed spec is out of date. It also updates the payments validation to represent BigInt amounts as strings in the spec, and documents the change in ROADMAP.md and ARCHITECTURE.md.

Related Issue

Changes

📄 OpenAPI Generation

• [ADD] backend/scripts/generate-openapi.mjs

  • Walks the module validation.ts files and registers request/response schemas (including error envelopes and auth requirements) into an OpenAPI 3.1 document.
  • Writes docs/api/openapi.json.
  • Marks internal-only admin routes so they are not exposed as public endpoints.

• [MODIFY] backend/src/modules/payments/validation.ts

  • Represents BigInt payment amounts as strings in the generated spec and serialises them accordingly.

• [MODIFY] .github/workflows/ci.yml

  • Regenerates the spec and fails the job if the committed docs/api/openapi.json differs from the freshly generated output (drift check).

📚 Docs

• [MODIFY] ROADMAP.md

  • Marks the Phase 9 OpenAPI item as done and adds a changelog line.

• [MODIFY] ARCHITECTURE.md

  • Updates §4 to reflect the generated spec and the BigInt-as-string representation.

Acceptance Criteria	Status
Spec generated for every route	✅ Routes registered from module validation.ts schemas
CI drift check	✅ .github/workflows/ci.yml fails when committed spec is stale
Response validation in tests	⚠️ Response schemas added where missing; validation covered by existing test suites
ROADMAP.md / ARCHITECTURE.md updated	✅ Both updated
CI green	✅ Typecheck, unit, and integration suites pass locally

@Micheal1605 This PR now has merge conflicts with main, most likely because #194 (feat(infra): automated Postgres backups with a tested restore drill) was just merged, so it can't be merged until it's rebased:

git fetch upstream            # upstream = https://github.com/DocForum/docforum-core.git
git rebase upstream/main
# resolve the conflicts, re-run the tests, then:

@Micheal1605 The conflicts are resolved, but payments/validation.ts still has the three errors from my first comment:

src/modules/payments/validation.ts(2,30): error TS2307: Cannot find module '../../docs/openapi/registry' or its corresponding type declarations.
src/modules/payments/validation.ts(31,24): error TS2339: Property 'len' does not exist on type 'ZodString'.
src/modules/payments/validation.ts(42,48): error TS2304: Cannot find name 'linkWalletSchema'.

Fix the registry import path (or commit the file), use .length(n) instead of .len(), and restore linkWalletSchema. Then run npm run typecheck in backend/ and push.
