What

• Each turn item keeps tokens (input, cacheWrite, cacheRead, output) from the usage of Claude Code's result, which is the sum of that turn's requests. costUsd is gone.
• The chat's turn line shows the tokens ("Done in 4.2 s · 2.5k tokens"); its title gives new read, written and reread.
• New usage.tokens {since} sums turns per bot (archived bots included). The usage dialog gets a "Tokens by bot" part: today, 7 days, 30 days, all time, with the total.
• The headline count is new input + cache written + output; the conversation reread from the cache is shown apart, as it weighs much less.
• Migration 0011 adds a partial index for turn items by time.
• Spec: new 8.7; 8.1, 8.2, 11.2, 12 and 19 updated.

Why no money

total_cost_usd is API list price and adds up the whole process, not the turn, so the old tooltip was wrong after the first turn; plan users do not pay it either.

Checked against real Claude Code (2.1.284)

A claude -p stream-json process with two turns, one using Read: result.usage is the sum of the turn's requests (input_tokens 18 = 10 + 8, cache_read_input_tokens 46703 = 21692 + 25011) and starts over each turn; modelUsage and total_cost_usd accumulate. Not verified: whether subagent tokens are in that usage (listed in spec 19).

Manual test

1. Send a bot two messages, one after the other finishes.
2. Each turn line shows its own token count; hover shows new, written and reread.
3. Account menu > Usage > Tokens by bot: the bot shows both turns added up; switch periods.
