# Session validity, separate from reimbursement

Platform v26.9.1 · Released 7 Sept 2026 · Feature

CPO sessions now separate two questions that used to be tangled together: is the session valid, and should it be reimbursed to the operator. Each carries its own status and its own reason, so it is always clear why a session was or was not paid out.

## What changed

### Added
- A Validity status (Valid / Invalid) on each CPO session, with the reason shown on hover (for example, started with an unauthorised token). Invalid sessions are always excluded from reimbursement.
- Reimbursement is tracked separately: a session can be valid yet still not reimbursed to the operator when Road did not acquire the funds for it, and each such session carries a reason.

### Improved
- A reworked sessions filter: grouped sections, multi-select dropdowns, filters on total cost and kWh, and filters on validity and reimbursement status.
- 'External Calculated Price' is now 'Total Cost - External', with tooltips explaining the difference from Total Cost.

## Rollout

Available to operators in the sessions overview.
