LADDEREVIDENCE MATURITY
Evidence Ladder
A lifecycle for producing review-ready evidence artifacts.
The ladder defines maturity. Reviewers apply standards externally and determine conclusions.
Steps
Capture → Normalize → Lineage → Governance → Outputs → Verify
L1 — Capture
Ingest measurements with identity, timestamps, and basic validation.
CONTINUITY
Ladder steps describe artifact maturity — not regulatory acceptance.
L2 — Normalize
Stabilize fields/units and define review windows for reproducibility.
INTEGRITY
Ladder steps describe artifact maturity — not regulatory acceptance.
L3 — Lineage
Fingerprint artifacts and make transformations inspectable.
LINEAGE
Ladder steps describe artifact maturity — not regulatory acceptance.
L4 — Governance
Record readiness posture, exceptions, and disclosure boundaries.
DISCLOSURE
Ladder steps describe artifact maturity — not regulatory acceptance.
L5 — Outputs
Produce packs and reports suitable for audit and disclosure workflows.
ARTIFACTS
Ladder steps describe artifact maturity — not regulatory acceptance.
L6 — Verify
Expose receipts and integrity references (optional anchoring).
VERIFICATION
Ladder steps describe artifact maturity — not regulatory acceptance.
