+# Data-Center / AI Infrastructure Governance Profile
+
+**Status**: APPLIED PROFILE DRAFT  
+**Scope**: evidence surfaces for AI infrastructure and data-center public-benefit claims  
+**Implementation status**: NOT_IMPLEMENTED  
+**Core mutation**: NONE
+
+## Purpose
+
+AI infrastructure is not only compute. It can affect energy systems, water systems, land use, heat flows, grid flexibility, public benefit, and local accountability.
+
+This profile uses Riverbraid's claim-versus-evidence pattern to make those claims inspectable.
+
+## Core question
+
+```text
+What public-benefit claims are being made, and what evidence supports each claim?
+```
+
+Riverbraid does not decide the politics of infrastructure. It can help prevent public-value claims from hiding inside fragmented paperwork.
+
+## Evidence surfaces
+
+| Surface | Question | Example evidence |
+|---|---|---|
+| Energy use | How much power is consumed and when? | metered load data, utility reports, interconnection records |
+| Water use | What water source is used and how much? | potable/reclaimed/closed-loop data, permits, water reports |
+| Heat reuse | Is waste heat reused? | thermal delivery records, heat reuse contracts, metered MWh thermal |
+| Grid flexibility | Can the site reduce load or support the grid? | demand response records, battery dispatch logs, response time evidence |
+| Compute commons | Is public or research compute offered? | allocated hours, user groups, access policy, usage logs |
+| Public benefit | What benefit is claimed and who receives it? | public ledger, community agreements, benefit reports |
+| Agency responsibility | Who is responsible for each claim? | agency map, owner map, escalation route |
+| Transparency | What is visible to public reviewers? | dashboard, audit packet, public reports |
+
+## Suggested metrics
+
+- PUE / WUE / CUE where relevant
+- MWh consumed
+- MWh thermal reused
+- percentage of water from non-potable or closed-loop sources
+- MW of flexible load
+- response time for grid events
+- battery capacity available for public/grid support
+- public compute hours allocated
+- local ratepayer cost impact
+- unresolved community burden reports
+
+## Claim record format
+
+```yaml
+claim_id:
+claim_text:
+claim_owner:
+evidence_required:
+evidence_available:
+verification_status:
+known_limitations:
+non_claims:
+responsible_agency:
+review_cadence:
+```
+
+## Failure behavior
+
+If a public-benefit claim lacks evidence, the claim should move to:
+
+```text
+CLAIM_UNSUPPORTED_PENDING_EVIDENCE
+```
+
+If a metric is promised but not measurable, the profile should mark:
+
+```text
+MEASUREMENT_SURFACE_ABSENT
+```
+
+## Non-scope
+
+This profile does not:
+
+- approve or reject a data center
+- claim environmental compliance
+- replace local permitting
+- replace utility review
+- certify public benefit
+- guarantee community consent
+- prove climate benefit
+
+## Boundary
+
+This is an applied profile draft. It does not create a live dashboard, legal status, infrastructure approval, or external audit claim.
