U04554 Experiment Design For Accessibility Services

Preflight:

• Validate mission scope, contracts, and required inputs.
• Verify feature flag posture, dependencies, and approval prerequisites.

Execution:

• Execute experiment design workflow with deterministic scoring and trace capture.
• Track posture transitions and preserve reproducible evidence artifacts.

Recovery:

• Apply rollback strategy if posture is critical or guardrails fail.
• Escalate blocked execution to oversight with incident packet and trace references.

Handoff:

• Publish outcome report, scorecard, and telemetry links.
• Queue follow-up tasks for unresolved risks, approvals, or optimization work.

Guardrails

• [quality] Require unit and integration validations before promoting Experiment Design for accessibility services. -> run-validation:unit+integration+simulation+regression-baseline
• [reliability] Trigger rollback on critical posture or repeated failures. -> rollback:rollback-to-last-stable-baseline
• [cost] Respect bounded resource pressure and execution budget during scaling. -> budget-guard:resource-pressure-cap
