Igny8 Tenancy System — Final Gap Analysis & Fixes

1. Payment Method & Subscription Model Gaps

Gap:

• Subscription and Account models only support Stripe (stripe_subscription_id is required/unique).
• No support for payment_method (bank transfer, PayPal) or external_payment_id.
• Docs and UI show bank transfer as active, but DB and API do not support it.

Fixes:

• Add payment_method (enum: stripe, paypal, bank_transfer) to both Subscription and Account (nullable, default stripe).
• Add external_payment_id (nullable) for bank transfer/PayPal reference.
• Make stripe_subscription_id nullable and drop unique constraint.
• Update serializers, admin forms, registration/subscription endpoints to accept and store payment_method.
• Backfill payment_method='stripe' for existing Stripe subscriptions.

2. API-Key Authentication Bypasses Plan/Status Validation

Gap:

• APIKeyAuthentication sets request.account but does not validate account/plan status.
• API-key clients (WordPress bridge) can access tenant endpoints even if account is suspended or plan inactive.

Fixes:

• Extract _validate_account_and_plan() from middleware to a shared helper (e.g., auth/utils.py).
• Call this helper in APIKeyAuthentication.authenticate() after resolving account.
• On failure, raise AuthenticationFailed with correct HTTP status (402/403).
• Add tests for API-key access with suspended/inactive accounts.

3. System Account/Role Handling

Gap:

• is_system_account() and related user methods remain, but bypasses are removed.
• Residual special-casing may exist; system accounts need explicit, controlled privileges.

Fixes:

• Decide: keep system accounts with tightly-scoped features, or remove hard-coded slugs and use explicit boolean/feature flags.
• Update code to use explicit privilege checks, not slug-based bypasses.
• Document system account handling in 00-system.

4. Throttle Policy

Gap:

• DebugScopedRateThrottle bypasses throttling for any authenticated user.
• No per-tenant rate limits; DoS risk.

Fixes:

• Only bypass throttling in DEBUG or for system/developer roles.
• Add per-account throttle keys (bucket by account.id).
• Add tests for throttle enforcement.

5. Middleware & Error Handling

Gap:

• Middleware skips validation for /api/v1/auth/ and /admin/.
• Silent fallback on JWT decode errors; may allow unvalidated access.

Fixes:

• Harden error handling: log token decode errors, fail requests explicitly.
• Ensure all endpoints require validated request.account for tenant access.
• Remove silent fallback in production.

6. Credit Deduction & Pre-Check

Gap:

• Credit deduction is centralized and correct, but pre-check for sufficient credits must always run before AI calls.

Fixes:

• Ensure every AI operation (Planner, Writer, etc.) calls CreditService.check_credits() before invoking external APIs.
• Add/verify tests for insufficient credits blocking AI calls.

7. Registration & Initial Credits

Gap:

• Registration flow seeds credits, but atomicity and idempotency must be guaranteed.

Fixes:

• Wrap registration in a DB transaction.
• Move credit seeding into an idempotent service method.
• Add tests for atomic User+Account+Subscription creation and credit seeding.

8. Bank Transfer Confirmation Endpoint

Gap:

• No admin API to confirm bank transfer payments; manual DB edits required.

Fixes:

• Add POST /api/v1/billing/confirm-bank-transfer/ endpoint (admin-only).
• Accepts: subscription_id|account_id, external_payment_id, amount, payer_name, proof_url/file.
• Marks subscription active, sets renewal dates, stores payment method and reference, tops up credits.
• Add CreditTransaction entry and update Account.credits.
• Add tests for bank transfer confirmation flow.

9. Tests & CI Coverage

Gap:

• No test coverage for strict tenant filtering, API-key gating, or bank transfer flows.

Fixes:

• Add unit tests for:
  • AccountModelViewSet filtering by account.
  • PermissionDenied on missing account context.
  • APIKeyAuthentication denying access for suspended/inactive accounts.
  • Throttle enforcement.
• Add integration tests for:
  • Registration and credit seeding.
  • Bank transfer confirmation endpoint.
• Add to CI pipeline.

10. Documentation & Admin UI

Gap:

• Docs and admin UI do not reflect new payment fields or flows.

Fixes:

• Update Final_Flow_Tenancy.md and 02-MULTITENANCY-MODEL.md to match new model.
• Update admin UI to show payment_method and allow bank transfer confirmation.
• Mark Stripe/PayPal as "coming soon" in UI.

---

Rollout Plan

1. Create DB migrations for new fields (nullable, default to Stripe).
2. Deploy code that tolerates nulls; backfill Stripe subscriptions.
3. Update API and admin UI to support new payment flows.
4. Add bank transfer confirmation endpoint.
5. Add and run tests; enable stricter logging/monitoring.
6. Gradually enable bank transfer in registration/checkout UI.

Rollback Guidance

• Revert UI → backend code → DB (reverse migration only if safe).
• Use feature flags for bank transfer flows.

---

Final Checklist

• Payment method fields and logic added everywhere (DB, API, UI)
• API-key validation enforced for plan/status
• System account logic explicit and documented
• Throttling per tenant, not blanket bypass
• Middleware and error handling hardened
• Credit checks before all AI calls
• Registration atomic and idempotent
• Bank transfer admin endpoint implemented
• Full test coverage for all flows
• Documentation and admin UI updated
