Record blocked operational-value design for setup security audit

[Copilot]

The daily setup-action security audit requires a deterministic direct operational-value metric with replayable historical assignment. The workflow’s free-form finding reports do not provide a stable finding-to-remediation binding.

• Study record

  • Adds the required operational-value study JSON.
  • Records a blocked outcome and the evidence limitation.
  • Documents rejected activity/output proxies, assignment ambiguity, and unavailable comparable baseline evidence.

• Scope

  • Does not add an evaluator or alter workflow behavior, avoiding a non-defensible remediation metric.

Original prompt

[operational-value-study:paper-v1] daily-action-setup-security-audit

Use the repository's .github/skills/operational-value-designer/SKILL.md to design
and verify one deterministic operational-value grader for github/gh-aw
workflow daily-action-setup-security-audit. This is a fresh research run; do not copy another
workflow's metric or contract.

Requirements:

• Recover adoption-time intent and pre-adoption evidence independently.
• Use exactly one direct primary attainment metric in [0,1]. Keep diagnostics separate.
• Treat unavailable evidence as null, never zero. Make maturation explicit and stable.
• Support historical assignment reconstruction when case and event are null.
• If no direct operational metric is defensible, create only the study record below with designOutcome "blocked" and explain why. Never substitute activity, output volume, traces, or agent judgment.
• Change only .github/workflows/daily-action-setup-security-audit.md, its generated lock file,
  .github/graders/daily-action-setup-security-audit-operational-value.sh, and .github/graders/daily-action-setup-security-audit-operational-value-study.json.
• Do not add generated historical reports to the pull request.

Write .github/graders/daily-action-setup-security-audit-operational-value-study.json as JSON with this exact top-level shape:

}]
}

For blocked/rejected designs, rejectionReason must be a non-empty string. Record
observable contract choices and alternatives only; do not record chain-of-thought.

Validation for accepted designs:

1. .github/skills/operational-value-designer/scripts/verify-operational-value-evaluator.sh .github/graders/daily-action-setup-security-audit-operational-value.sh
2. gh aw compile .github/workflows/daily-action-setup-security-audit.md

Keep the pull request limited to this workflow. The local study runner will replay
history and archive reports after this task completes.
