A generic multi-client payment gateway so FlatRender, meezi.ir and bargevasat.ir can all pay through ZarinPal's single verified callback domain (pay.flatrender.ir). New Go service services/payment (clones the notification skeleton + vendored deps): - migration 31_payment_broker.sql — `payment` schema: client_apps, transactions, webhook_deliveries. - ZarinPal v4 client ported from the proven identity PaymentService (request.json -> StartPay -> verify.json; codes 100/101). - client API: POST /v1/pay/request + /v1/pay/inquiry, authed by X-Api-Key + HMAC body signature; GET /callback/zarinpal (the single verified endpoint) verifies, then 302s the user back to the site's return_url (signed) and fires a signed, retried webhook. - per-client ZarinPal merchant override (default = shared merchant); amount stored canonically in Rial, unit to ZarinPal env-configurable. - admin API /v1/admin/* (FlatRender admin JWT): client-app CRUD + key issue/rotate + transactions list. Deploy wiring: payment-svc in docker-compose.v2.yml (host port 1607), pay.flatrender.ir server block in mirror-nginx conf, ENV_FILE + README updates (cert SAN + manual migration note). Admin UI: src/components/admin/PaymentsAdmin.tsx (client apps with one-time key reveal + rotate, transactions table) + /admin/payments page + nav link + fa/en strings; pay-admin proxy route to payment-svc. Docs/SDK: deploy/PAYMENTS.md (integration contract) + deploy/sdk/flatpay.js (zero-dep Node client + webhook verifier) for meezi/any site. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Schemas
| Schema | Owner Service | Purpose |
|---|---|---|
identity |
Identity Service (.NET) | tenants, users, auth, plans, payments, gamification |
content |
Content Service (.NET) | templates, scenes, presets, blogs, CMS |
studio |
Studio Service (.NET) | user's saved projects + audio (music/voiceover/sfx) |
render |
Render Orchestrator (Go) | jobs, nodes, frame jobs, snapshots, exports |
file_mgr |
File Service (Go) | user files, folders, quotas, cleanup |
notification |
Notification Service (Go) | in-app, push, email, SMS, telegram |
Cross-schema design
Schemas are loosely coupled. Where it matters for integrity (within a service), FKs are used. Across services, FKs are deliberately omitted so services can evolve independently — referential integrity is enforced via service code and events.
Hard FKs across schemas (intentional)
identity.earned_gifts.notification_id→notification.notifications.id
Everything else uses soft references (column documented but no FK).
Multi-tenancy
identity.tenants is the root of multi-tenancy. The default FlatRender
tenant has UUID 00000000-0000-0000-0000-000000000001.
Every user, project, render job, file, and notification carries a
tenant_id. Resellers (B2B API customers) are tenants. White-label
branding, API keys, webhooks, and usage metering all hang off
identity.tenants.*.
New features (vs V1)
- Multi-tenancy / Reseller API:

music_volume,sfx_volume,voiceover_volume - Scene snapshots:
render.snapshotswith cache key - AE crash tracking:
render.node_crashes+ auto-recovery - Frame repair jobs:
render.frame_repair_jobs - AEP local cache on nodes:
render.node_template_cache(LRU) - SVG color previews:
content.template_svg_previews(drop image → traced SVG) - PWA push subscriptions:
identity.push_subscriptions - MFA:
identity.mfa_factors - Multipart uploads:
file_mgr.upload_sessions - Cleanup scheduler:
file_mgr.cleanup_schedules - Per-user / per-channel notification preferences:
notification.notification_preferences
Partitioning
Time-series tables are partitioned monthly (initial partition for 2026-01 created; ops creates new ones via cron):
identity.tenant_api_request_logsrender.node_health_logs
Service user grants
Each microservice connects with its own DB role limited to its schema.
See top of 00_setup.sql for the recipe.
