What it supports
The mechanics can fit together.
- Lifecycle, customization, and company-content actions passed through one gateway and policy implementation.
- Exact approvals, idempotency, append-only receipts, provenance, projection rebuild, and replay stayed coherent.
- Two local payload shapes implemented the contract without reducing everything to one database.
- Adversarial fixture tests covered tenant boundaries, injection-as-data, retries, failures, restore staging, and evidence tampering.
