Eval Governance: Gates and Sign-off — Guardrails and Fix Patterns

🧭 Quick Return to Map

You are in a sub-page of Governance.
To reorient, go back here:

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

Evaluation disclaimer (governance gates)
Governance checks and scores here are example patterns for one org and threat model.
They support decision making but are not legal guarantees or formal safety certifications.


A governance control page for evaluation pipelines, approval gates, and release sign-off.
Use this page when models are shipped without evaluation, when sign-offs are missing, or when evaluation metrics drift without detection.


When to use this page

  • Model released with no reproducible evaluation.
  • Evaluation set not tied to lineage or version.
  • Sign-off done informally or not logged.
  • Thresholds vary arbitrarily across teams.
  • Failures pass through without regression detection.

Acceptance targets

  • Coverage ≥ 0.70 of target section in eval set.
  • ΔS(question, retrieved) ≤ 0.45 across governed evals.
  • λ_observe remains convergent across three paraphrases and two seeds.
  • Every sign-off has owner, date, thresholds, and waiver expiry.
  • Regression gates block release when ΔS ≥ 0.60 or coverage < 0.70.
  • Sign-off artifact immutable and joinable to lineage.

Typical breakpoints and WFGY fix


Minimal governance checklist

  1. Immutable eval set with versioned hash tied to release.
  2. Threshold contract documented in governance policy.
  3. Dual sign-off required (technical + governance approver).
  4. Waivers expire and are linked to a risk register entry.
  5. Regression gates enforced in automation, not manual process.
  6. Audit trail: stored in lineage, accessible for inspection.

Example: Sign-off schema

{
  "model_id": "v2.1.4",
  "eval_set_hash": "f89a1c3e...",
  "ΔS_threshold": 0.45,
  "coverage_threshold": 0.70,
  "signoff": [
    {"role": "tech lead", "name": "Alice", "date": "2025-08-25"},
    {"role": "governance officer", "name": "Ravi", "date": "2025-08-26"}
  ],
  "waivers": [
    {"risk_id": "R-223", "expiry": "2025-12-31"}
  ]
}
