Public discovery is open. Execution is bounded, quoted and separated by trust level.
9192 is designed around narrow public routes, explicit paid execution gates, signed releases, receipt verification and operator-local secret storage.
Current controls.
These controls are already represented in the public product surface or local operational tooling.
Controls to harden next.
These are the measures to finish before inviting broader external usage.
External readiness checklist.
This maps the product to familiar security expectations without claiming certification.
Define owner, abuse contact, incident process, backup cadence, rotation cadence, dependency review, API limit policy, release signing policy and uptime target.
Use OWASP API risk review for authorization, authentication, resource limits, object-level access, mass assignment, SSRF, unsafe consumption and misconfiguration.
Prepare a control matrix for security, availability, confidentiality and processing integrity. Keep proof of probes, deployment changes, release signatures and incident drills.
Keep financial language narrow: 9192C remains an internal accounting reference unit, and paid execution is explicit quote plus funded account only.
