- Execution and observation records
- Reconciliation outcomes
Runtime and execution assurance
Certification and Audit Ledger
Linked records, not a certification badge.
Per-component hash-chained decision, permit, execution and outcome records with lifecycle reconstruction and explicit evidence boundaries.
Responsibility
What Certification and Audit Ledger is responsible for
The Certification and Audit Ledger keeps ordered, hash-linked records for decisions, permits, execution attempts and reconciliation outcomes. It verifies component chains and builds a lifecycle reconstruction artefact. The name is architectural: no certification, WORM storage or external audit attestation is claimed.
Accountability requires records that can be reviewed after the fact. Each component keeps an ordered, hash-linked chain; the ledger verifies those chains and reconstructs the transaction from decision to outcome.
What the ledger is not matters as much as what it is. It is not a certification authority, not immutable WORM storage, not an external anchor and not a single signed envelope. Those boundaries are stated wherever the ledger is described.
Lifecycle position
Where it sits in the governance lifecycle
Stage numbering is canonical across the site. Open the interactive lifecycle to see every component with responsibilities at each stage.
Evidence and audit
Keep linked, ordered, reviewable records.
Conformance
Evaluate outcomes against the original obligations.
Verified capabilities
What is verified today
Capabilities are drawn from the product register. Each one is bounded by the limitations stated further down this page.
- Per-component hash-chained audit records
- Chain verification and ordered lifecycle reconstruction
- Correlation of decision, permit, execution and outcome by identifier
- Anchor publisher client for future external anchoring
Outputs
- Verifiable component chains
- Lifecycle reconstruction artefact
- Evidence references for conformance
Evidence and maturity
What the evidence supports
Maturity describes verified engineering evidence in a bounded environment. It is not a production-readiness statement.
Maturity note
Both component chains were verified and a lifecycle reconstruction artefact was produced on the recorded chain. The ledger is tamper-evident per component, not WORM, and no single signed envelope spans every component.
Not production-qualified
This label describes verified engineering evidence only. No production deployment, certification, benchmark or customer outcome is claimed.
Evidence recorded
- Acceptance step 12: both component chains verified and lifecycle reconstruction written.
- Audit integrity cases passed with durable ordering and restart recovery.
- Anchor publisher/verifier client exists; no external anchor destination configured.
Dependencies
- Control Plane
- Gatekeeper
- NARG
- Reconciliation
Dependencies are stated as the product register records them. A dependency is not automatically production-qualified; see its own product or component page for its maturity and limitations.
Limitations
What this product does not do (yet).
Limitations are stated before the evaluation questions so they cannot be missed, downplayed or treated as future-work footnotes.
Limitations — read before evaluating
- Hash chaining is tamper-evident, not WORM storage.
- No external anchor destination is configured, and no third-party auditor validates the chains.
- No single signed lifecycle envelope spans every component; correlation is by identifier.
- The name 'Certification and Audit Ledger' is architectural and does not imply a certification.
No capability on this page should be read as production qualification. If a limitation is material to your use case, it belongs in the evaluation scope — not after it.
Relationship to the platform
How it fits
The ledger is the evidence spine consumed by conformance evaluation and AIOps findings. It does not create authority or prove business correctness by itself; it makes the records inspectable and linked.
Evaluation questions
- Which records must be retained for your review obligations?
- Can a reviewer reconstruct the whole transaction from records?
- What would external anchoring or third-party audit require?
Next step
Evaluate Certification and Audit Ledger against a real control problem.
Bring a system boundary, an action class and a failure mode. The first step is to agree what should be governed and what evidence would count.
