Evaluation Auditability
Build a defensible evaluation and audit layer for agents in science, civic systems, and other high-stakes workflows.
8 skill artifacts · Draft · GROW-S2 (Systems cluster)
What this module contains
8 reusable skill artifacts.
Each artifact is a standalone, versioned build deliverable — templates, registers, policies, specs, checklists, matrices, playbooks, and maps — wired to the rest of the GROW stack by explicit contracts.
The Evaluation Charter declares what a GROW-built system must prove before it is allowed to act on behalf of a user, a constituent, or an operating business.
Builds on: s1-failure-mode-register
This schema is the contract with GROW-S3 (Data Provenance).
Contract: Produces C3 → Provenance
Builds on: c9-execution-accountability, e6-routing-policy, s2-evaluation-charter
The roster names who — human or automated — is allowed to sign off on what, when they are invoked, the scope of their authority, what artifacts their sign-off produces, and where escalation goes when they cannot or should not decide alone.

A test architecture is conformant when:

The Scoring System turns raw test verdicts and provenance records into a single, defensible scorecard with explicit pass thresholds, severity weighting, confidence handling, and drift indicators.
Builds on: s1-failure-mode-register, s2-audit-trail-schema, s2-eval-test-seed-matrix, s2-evaluation-charter, s2-evaluator-roster, s2-test-architecture, s3-decision-traceability, s3-provenance-metadata-schema, s3-provenance-package-templates, s3-source-inventory-template
Regression discipline is how GROW prevents the most common operational failure: a "small change" that quietly breaks a previously-passing behavior.
Builds on: s2-evaluation-charter, s2-test-architecture, s2-audit-trail-schema, s2-scoring-system, s2-evaluator-roster, s3-reproducibility-controls
Six fillable scaffolds.

Build & gate status
Where this module stands.
Status
Systems cluster — validated by the v2 integration gate (READY WITH CORRECTIONS).
How it composes
This module plugs into the four-cluster GROW stack (Systems → Execution → Trust → Coordination) through versioned interface contracts C1–C12. See the full wiring in the library registry.
Open access
GROW-S2 is free and open.
Every artifact, worksheet, and template in this module is free to use — no membership, no paywall.
