- Webhooks: HMAC-signed, replay-protected, idempotency keys
- Retries: exponential backoff + DLQ via Redis streams
- Audit: append-only store, tamper-evident hash chain, export to SIEM
- Policy: PII masking, RBAC, least-privilege secrets, key rotation

Deliverables:
- Code (NestJS/TypeScript) + OpenAPI
- Docker + Helm charts
- CI: tests, SAST, SBOM, license checks
- Runbooks + dashboards (Prometheus/Grafana)

Starting full implementation with example connectors, sandbox mode, and integration tests.

- AuthZ: RBAC + tenant scoping
- Tooling: proto + client SDKs, contract tests

Outputs:
- Services + Dockerfiles + Helm

[Assistant]
Solution:
- Isolation: per-tenant Postgres schema or cluster + RLS; KMS key per tenant; secrets via Vault
- Rate limits: token bucket per tenant via Redis; burst + sustained quotas
- Residency: region-specific data stores + routing via geo-aware gateway
- Observability: per-tenant metrics, logs with scrubbed PII
- Deploy: Helm values per region; CI pipeline for per-tenant config

Deliverables: diagrams, IaC templates, policy-as-code (OPA), and tests validating isolation and limits.
