Evidence Infrastructure

ARAF does not treat evidence as a documentation appendix. Evidence is governance infrastructure: the operational layer that allows institutions to answer the accountability questions that matter under board review, insurance analysis, regulatory inquiry, and litigation.

Why Evidence Infrastructure Matters

Autonomous decisions are produced through a Decision Supply Chain, not a single actor. Governance claims are therefore only as strong as the records that follow decisions across the full chain.

Without evidence continuity, accountability becomes narrative.

With evidence continuity, accountability becomes demonstrable.

The governing test remains the same for every consequential decision:

who was responsible
what did they know
what did they do

The Four Evidence Categories

ARAF evidence architecture is organized into four categories that map to governance lifecycle stages.

Category	Governance Question	Typical Records
Design Evidence	Was governance architecture adequate at design time?	Classification record, scope boundaries, training data provenance, pre-deployment risk assessment
Deployment Evidence	Was deployment approved under defined governance conditions?	Environment assessment, integration governance record, oversight assignment, production readiness decision
Operational Evidence	Was governance exercised during live operation?	Monitoring logs, anomaly records, escalation records, reassessment triggers, AIOC decisions
Outcome Evidence	Can adverse outcomes be investigated and attributed?	Incident record, accountability determination, response actions, remediation record

Coverage across all four categories is required for reconstructability.

1. Design Evidence

Design evidence establishes what was built, what governance assumptions were made, and what risk posture existed before production operation.

Minimum design evidence should include:

ARAF dimensional profile and initial GBI reasoning
declared autonomy scope and out-of-scope boundary definitions
training and fine-tuning data provenance basis
pre-deployment governance risk assessment
design-time accountability assignments

If design evidence is absent, later claims about intended governance controls are difficult to verify.

2. Deployment Evidence

Deployment evidence proves that production authorization was a governance decision, not only an engineering event.

Minimum deployment evidence should include:

deployment environment assessment
integration risk and control mapping
named accountability holders for live operation
production readiness determination with date and approver
applicable contractual and jurisdictional controls at go-live

If deployment evidence is absent, institutions cannot reliably determine whether governance was exercised at the point risk became real.

3. Operational Evidence

Operational evidence demonstrates that governance remained active after go-live as systems changed and decision volume scaled.

Minimum operational evidence should include:

periodic governance monitoring records
threshold breach and anomaly records
escalation and intervention records
reassessment trigger logs
AIOC or equivalent oversight decisions

Engineering telemetry alone is not sufficient. Operational evidence must show governance action, not only system performance metrics.

4. Outcome Evidence

Outcome evidence supports investigation and attribution when decisions are challenged.

Minimum outcome evidence should include:

incident timeline linked to decision IDs
accountability analysis by chain link
response actions and responsible parties
remediation actions and closure verification
post-incident governance adjustments

If outcome evidence is produced only after an event from fragmented sources, the record is reconstructed rather than contemporaneous.

Evidence Continuity Across the Decision Supply Chain

Evidence continuity means records remain linked across every material Decision Supply Chain link, including data inputs, model interaction, human review, and execution.

Evidence continuity requires:

stable decision identifiers across chain stages
link-level accountability assignment records
handoff records between systems and actors
time alignment across records (event chronology)
cross-entity record availability under contractual terms

A chain with one unrecorded link is accountability-incomplete.

Governance Records: Quality Requirements

ARAF governance records should satisfy the evidence quality requirements used in assessment:

Authenticity: record origin is verifiable
Integrity: tampering is detectable
Traceability: record is linked to decision, system, and accountable party
Exportability: record can be produced for independent review

These properties determine whether institutional audiences can rely on the record without reproducing the underlying governance process.

Reconstructability Standard

A decision is reconstructable when an independent reviewer can, from records created during operation, determine:

what decision was made
which inputs and controls governed the decision
which actors/systems participated in the chain
which accountability holder approved or supervised the relevant link
what response occurred after anomalies or adverse outcomes

Reconstructability is the operational proof condition for institutional reliance.

Relationship to Assessment and Certification

Evidence Infrastructure supports assessment and certification but is not identical to either.

Assessment evaluates governance posture using evidence inputs
Certification communicates assessment outputs as an institutional signal
Evidence Infrastructure produces the records that make both credible

No evidence infrastructure means low confidence governance claims, even where policy statements exist.
