Why it matters for cost
JP reads Codex used_percent automatically and Claude's only via the opt-in statusline capture — never an estimate.
How JP the Cat surfaces it
JP the Cat reads the real token counts behind this from the local logs on your Mac and prices them at the shipped rates — so it shows up in your actual cost, not an estimate.
