fix: enforce API-layer DB access boundary across billing-service, admin-service, and core-api controllers by Copilot · Pull Request #333 · NickLetts2/Curvit

Copilot · 2026-05-30T04:10:42Z

billing-service and admin-service were writing directly to core-api-owned tables via SQLAlchemy, and four core-api controllers were injecting CurvitDbContext directly instead of going through the repository layer. This eliminates all violations and adds pre-commit guards to prevent regression.

core-api

New repository interfaces + implementations

IAuthUserRepository, IAppConfigRepository, IDpaRepository, ISystemSettingsRepository in Curvit.Application.Interfaces
Implementations in Curvit.Infrastructure.Persistence.Repositories
IUserAccountRepository extended with FindSubjectIdByIdAsync

Controllers refactored off CurvitDbContext

AccountSettingsController → IAuthUserRepository
ConfigController → IAppConfigRepository
ScreeningController → IUserAccountRepository + IDpaRepository + ISystemSettingsRepository
AdminDataExportController → IUserAccountRepository

New internal HTTP adapters (legitimate CurvitDbContext users — these are the boundary)

InternalBillingController — billing plan, subscription, webhook dedup, audit log writes
InternalAdminController — plan changes, restrictions, DSARs, retention settings, system settings, activity audit log

billing-service & admin-service

Both services now communicate with core-api over HTTP via a typed core_api_client.py using httpx.AsyncClient with X-Internal-Api-Key auth. SQLAlchemy session.add() / session.commit() calls are gone from all write paths.

# Before
account.plan_tier = plan_tier
account.stripe_subscription_id = None
session.commit()

# After
await core_api_client.update_account_plan(account_id, plan_tier, audit_ctx)
await core_api_client.clear_account_subscription(account_id, audit_ctx)

Pre-commit enforcement

Two new checks added to .githooks/pre-commit:

Python write guard — fails if session.add( or session.commit( appears in billing-service/app/ or admin-service/app/ (tests excluded)
C# controller guard — fails if CurvitDbContext appears in any Controllers/*.cs file that isn't prefixed Internal

Pull request overview

This pull request enforces a stricter service boundary around core-api–owned database tables by moving billing-service/admin-service write paths to core-api internal HTTP endpoints and refactoring core-api controllers away from direct CurvitDbContext usage. It also introduces a new unified content platform (ContentItems) with cms-service routes/tests/docs and an EF Core migration.

Changes:

Added core-api repository interfaces/implementations and refactored controllers to use repositories instead of injecting CurvitDbContext.
Added core-api internal adapters (InternalBillingController, InternalAdminController) and updated billing-service/admin-service to use typed httpx clients instead of SQLAlchemy writes.
Introduced a unified content platform (new ContentItem entity/table + cms-service API + tests + documentation) and added pre-commit guards to prevent boundary regressions.

This is intentional. The content platform (new ContentItems table + EF entity/config + migration + cms-service routes/tests/docs) is a deliberate part of this PR. The PR description has been updated to explicitly call it out as a separate section alongside the API-layer boundary enforcement work, so reviewers are aware of the full migration and data-model scope.

@copilot resolve check failures

The CI Observability failure was in step [8/8] of validate-observability.sh — the dev docker compose config check was running without an env file, but docker-compose.yml declares REDIS_PASSWORD and GRAFANA_ADMIN_PASSWORD as required variables (:? syntax). The root .env.example already contains placeholder values for both, so I added --env-file .env.example to that command. All 8 validation steps now pass locally.
