Data source truth
Charging surfaces depend on real charge sessions, energy, state-of-charge changes, and any owner-provided cost context. EVStreak should not fabricate savings.

Charging
Charging becomes a ledger, not another spreadsheet.
Charging sessions become a quiet ledger for energy, cost-ready context, and ownership rhythm once real sessions exist.
Failure and empty state
Before a charging session exists, the page explains what will be captured later and avoids fake ledger rows.
Privacy note
Charging context can imply home, route, and routine patterns. EVStreak should summarize sessions without exposing sensitive raw telemetry publicly.
What it does
Charging turns sessions into a useful ledger: when energy was added, what changed, and where cost context belongs when available.
Claim rules
The first public MVP should sell clarity, not fake savings. Cost and carbon claims require real data or user-supplied values.
Empty state
If no session exists, the page should hold the space and state exactly what unlocks after the first real charge.
