Evidence Architecture Layer
A neutral layer that defines how truth flows across hydrogen, water, energy, cooling and contractor-heavy operations.
What the layer is
RGRA is neutral evidence architecture, not software.
It sits above operations and systems, defining how events, responsibilities and proofs should connect.
There is no data access, no integrations and no disruption to existing IT.
The layer is designed to work alongside existing advisors and vendors – including Big4, boutiques and OEMs – without replacing or competing with them.
Four pillars
Identifying the critical operational flows that must be defensible under audit, regulation or board scrutiny.
Clarifying who is accountable at each step and how their actions are evidenced and locked.
Ensuring when things happened is provable, tamper-resistant and replayable across days, weeks and quarters.
Documents, logs and checks sealed into daily evidence states that can be replayed without rework.
Evidence domains
| Domain | Evidence chain | Typical pressure |
|---|---|---|
| Green Hydrogen | Production → storage → offtake | Certification, claims, reporting and assurance. |
| Water & Desalination | Abstraction → treatment → delivery → billing | Non-revenue water, leakage, billing integrity. |
| District Cooling | Capacity → flows → outages → customer impact | SLAs, penalties, outage traceability. |
| Contractors & Mega-Projects | Scopes → hand-offs → approvals → claims | Disputes, delays, variations and overruns. |
What an evidence chain contains
An RGRA evidence chain specifies, in plain language:
- Operational events and their required sequence.
- Roles and responsibilities tied to each event.
- Documents, logs and artefacts accepted as proof.
- Rules – what must happen before or after each step.
- End-of-day locks that freeze the state for audit and replay.
How it lands
Each deployed chain is engineered to be operated locally, under your governance, without introducing new platforms.
The output is an audit-ready blueprint your teams can run in their own environment, with or without further RGRA involvement.
