Private model + frontier fallback

Goal

Design private model + frontier fallback with explicit authority, deployment, evidence, and recovery boundaries.

Architecture

Place MC-1 between the application and eligible execution paths. Apply hard policy and authority constraints before optimization, then retain decision evidence.

Prerequisites

• An authenticated organization and project with the required entitlement.
• A server-side MC1_API_KEY and deployed MC1_BASE_URL.
• Named owners, accepted data classes, success criteria, and rollback authority.

Code

curl "$MC1_BASE_URL/providers/health" -H "Authorization: Bearer $MC1_API_KEY"
curl "$MC1_BASE_URL/policies" -H "Authorization: Bearer $MC1_API_KEY"
curl "$MC1_BASE_URL/usage" -H "Authorization: Bearer $MC1_API_KEY"
# Validate these deployed facts for: Design private model + frontier fallback with explicit authority, deployment, evidence, and recovery boundaries.

Explanation

The example establishes a bounded starting point. Replace fixture identifiers with authorized project resources, inspect the returned route or workflow evidence, and promote only after the acceptance checks pass.

Where the implemented repository exposes no public mutation API, the code verifies current evidence and the named mutation must be completed through the authenticated console or deployment-controlled operator workflow. The documentation does not invent an unsupported endpoint.

Security considerations

• Keep all credentials server-side and redact them from logs.
• Minimize input data and enforce tenant, region, provider, identity, and tool boundaries.
• Require exact, time-bound approval before consequential writes.

Cost considerations

• Set a request or workflow ceiling before execution.
• Count retries, evaluation, human review, and provider costs separately.
• Treat forecasts and modeled savings separately from measured outcomes.

Testing

• Run against an owned synthetic fixture first.
• Test success, denial, timeout, cancellation, and unavailable-provider paths.
• Assert output or workflow evidence, route attribution, and unchanged unauthorized resources.

Production notes

• Pin client and integration versions.
• Canary the smallest reversible scope.
• Monitor policy decisions, quality, latency, spend, and rollback signals.
• Retain an accountable runbook and evidence window.
