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

🧭 Quick Return to Map

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.

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

No evaluation attached to release
→ policy_baseline.md
Require canonical eval policy before model moves forward.
Unlogged or informal approvals
→ audit_and_logging.md
Enforce immutable sign-off records.
Eval sets drift or vanish
→ data_lineage_and_provenance.md
Track provenance of datasets and eval snapshots.
Thresholds applied inconsistently
→ regulatory_alignment.md
Align thresholds with governance policy and external compliance.
Regression passes undetected
→ regression_gate.md
Block deployment on failing ΔS or λ.

Minimal governance checklist

Immutable eval set with versioned hash tied to release.
Threshold contract documented in governance policy.
Dual sign-off required (technical + governance approver).
Waivers expire and are linked to a risk register entry.
Regression gates enforced in automation, not manual process.
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"}
  ]
}
