Payroll is not available yet. Its statutory outputs have not been reviewed by a chartered accountant and are not described as compliant, so no plan and no trial includes it. The engines compute EPF, ESI, professional tax by state, labour welfare fund and TDS, and a review is the next thing scheduled before it is released.
The cross-tenant access log is best-effort rather than fail-closed. A support session that could not write its log entry proceeds anyway, because a logging failure taking down an engineer mid-outage is the worse trade. It means “every access is logged” is true in practice rather than guaranteed under failure.
Each deployment publishes its own list. Inside the product, at Settings → Security, is every guarantee that particular deployment is not currently keeping — the email driver, the file scanner, the job runner, the storage backend. It is generated from the running configuration rather than maintained by hand.
