Shared Evidence Layer

Evidence Fabric: the proof layer behind AI-assisted work.

Evidence Fabric is the shared evidence layer across CloudSeals applications. It records source context, model/agent details, purpose, policy/authority context, outcomes, approvals/overrides, downstream actions and final results.

Evidence Fabric example record linking source data, AI agent, policy context, human approval, downstream action and retained evidence.
Illustrative evidence record.

Evidence record fields

Source context

System, file, sensor, ledger or workflow source used by the AI-supported process.

Policy context

Applicable rule, operating procedure, approval threshold or regulatory reference.

Human decision

Reviewer, approval status, exception reason and final action separated from AI recommendation.

Model and agent details

Which model or agent produced the recommendation, so a reviewer knows what they are looking at.

Purpose

What the AI-supported step was for — the reconciliation, the safety rule, the carbon figure.

Authority context

Who was entitled to approve, and the limits that applied to them.

Outcome, approvals and overrides

What the AI proposed, what the person decided, and any override with its reason.

Downstream actions and final results

What was carried out after approval and what the final result was.

Retention, access, export and review

Retention

A configured decision per deployment, not a fixed default, because reporting and audit obligations differ by organisation and jurisdiction. See Security.

Access

Controlled through identity and access management; use of the record is itself recorded.

Export

Records are readable in the application and exported where the workflow needs it — for example, CarbonSight exports evidence for assurance and reporting.

Review

Written for someone who was not there: an internal reviewer, an auditor or a regulator can follow what happened and on what basis.

Who it is for, and how it is obtained

Evidence Fabric is used by the reviewers who make decisions in LedgerSight, CompliSight and CarbonSight, and read by the auditors and regulators who check them. It is not purchased separately: it comes with each application, and the deployment model is agreed per engagement. It is the evidence layer of what CloudSeals calls an accountable AI platform.

Evidence Fabric connects source information, policy context, human review and workflow outcomes in a reviewable record.

Where this is heading

CloudSeals research is extending TrustOps and Evidence Fabric into governed digital twins — how policy, simulation, human authority and evidence could govern increasingly autonomous cyber-physical operations.

Research direction, not a product. Not a separate product. Not currently offered as a production capability.

Why a shared layer

If each application keeps its own notes, an auditor has to reconcile three stories. A shared evidence layer means a finance exception, a safety alert and a carbon figure are all recorded the same way — same fields, same shape, one place to look.

One record shape

Source, purpose, policy context, decision and outcome are recorded the same way across applications.

Written as work happens

The record is produced by the workflow, not assembled afterwards from memory.

Readable by a reviewer

The point is that someone who was not there can follow what happened.

What Evidence Fabric is not

Worth stating plainly, because evidence claims attract scrutiny.

Not a separate product

It is the shared layer underneath LedgerSight, CompliSight and CarbonSight.

Not a compliance guarantee

It records what happened. Whether that satisfies a given regulation is a judgement made by your auditors and regulators.

Not a replacement for your systems of record

It records the decision context around the systems you already run.

Questions we get asked

What is Evidence Fabric?

Evidence Fabric is the shared evidence layer across CloudSeals applications. It records source context, model/agent details, purpose, policy/authority context, outcomes, approvals/overrides, downstream actions and final results.

What exactly is recorded?

Source context, model and agent details, the purpose of the action, the policy and authority context that applied, the outcome, approvals and overrides, downstream actions and final results.

Is Evidence Fabric something I buy separately?

No. It is the shared layer beneath the CloudSeals applications rather than a separate product.

Does an evidence record prove compliance?

It gives a reviewer what they need to follow a decision. Whether that meets a particular obligation is decided by your auditors and regulators, not by the software.

Who is the record written for?

Someone who was not in the room — an internal reviewer, an auditor, a regulator — reading it after the fact.

How does this relate to TrustOps?

TrustOps is the operating discipline for accountable AI and requires that a record exists. Evidence Fabric is where that record lives.
