One operating spine
Each stage preserves the context created by the one before it.
- 01
Capture
A person, meter, import or sensor creates the source record.
- 02
Control
Ownership, review, exceptions and factor lineage stay attached.
- 03
Close
The period locks and a signed, independently verifiable pack leaves.
Field capture & asset operations
The operating record starts at the equipment—not in a reporting template.
Locations, assets, work orders and inspections establish who did what, where and when. Fuel and service evidence inherit that context instead of arriving as an orphaned receipt.
- Role-specific My Work for technicians and supervisors
- Offline-ready inspections and evidence replay
- Asset, location and custody history on one timeline

Scope 1 & 2 control
Every number keeps its source, decision and explanation.
Fuel, refrigerants and purchased energy flow into a governed ledger. Reviewers work the exceptions, retain factor provenance and can see whether the period is actually ready to close.
- Fuel, refrigerant and electricity activity records
- Factor version, method and reviewer retained
- Close readiness and unresolved exceptions visible together

Evidence & assurance
The hand-off to an auditor is a workspace, not an email attachment hunt.
Assurance engagements, sample requests and evidence responses remain connected to the closed records. Exports carry a signed PDF, structured data and a public verification path.
- Engagement and sampling workflow
- Append-only audit history and evidence hashes
- Ed25519-signed packs verifiable without an account
