How it counts

• USD is what /cost reports, counted per turn from the moment the mod loads.
• Each session writes its own s:<session-id>:<day> key to the plugin store (~/.claude/plugins/store/cost-pane_inline-*.json). Daily totals sum every session; keys older than 30 days are pruned.
• Days are Vietnam time (UTC+7), set in dayOf in hooks/register.tsx.
