Latest update April '26 - New Registered Flow

From Systems to System Models

As part of this update:

• Systems pages are now renamed to Models
• This reflects their role as structured, reusable representations of carbon data. 

Registered Flow Benefits

Before this release, Models had a risk of change while being used for registration, reporting or verification.

Now:

A verifier cannot issue an opinion on a system whose inputs are still mutable.

The Registered flow solves this by:

• Locking data to initiate the verification and/or registration process
• Creating a clean, auditable snapshot
• Enabling reliable Carbon Receipt (CAP) issuance and Verification at a point time statement

Key Features Introduced

1. Registered Tab created

• A dedicated space where all registered models are stored
• Acts as a central hub for:
  • Verification
  • Carbon Receipts (CAPs)
  • Status tracking

2. New Action: Register

Found in the three-dot menu on Models.

Conditions:

• Model must be in Ready status
• All Properties fields must be completed (even if not required for Ready)

To Register a Model

When a user clicks Register:

Model Behavior

• The Model is copied with new IDs
• Original model remains unchanged
• The Registered version becomes:
  • Read-only (locked)
  • Used for:
    • Carbon Receipts
    • Verification

Important Rules

• Comments are NOT copied
• There is no unlock option
  • Exception: if status changes to Revisions Requested

Handling Linked Systems

Without Subsystems

Simple confirmation modal:

• Explains model will be copied and locked
• Lists next steps (CAP + Verification)

With Subsystems

Pop-up window displays:

• List of all linked systems
• All are:
  • Copied
  • Locked together
  • Assigned new IDs

Status Flow & Available Actions

Each registered model follows a defined lifecycle:

Verification Flow Updates

Request for 3rd Party Verification

• Opens right sidebar
• Initiates verification process

Add Verification Information

• Opens right sidebar
• Uses fields previously in Systems/Output node:
  •  Verification tab (now deprecated)

Behavior Change

• Once verification info is added:
  → Status automatically becomes Verified

Cleanup & Deprecations

• Verification tab removed from Outputs
• All verification now centralized in Registered flow

What This Means for You

This update enables:

• ✅ Reliable verification workflows
• ✅ Immutable audit-ready data
• ✅ Clear separation between modeling and reporting
• ✅ Scalable foundation for verifier roles & engagement

In Short

Before:
Editable systems → unclear verification readiness

Now:
Editable Models → Registered (locked) → Verification → Certified outputs
