 - **The headline total** adds session cost that no collector record carries, so newly priced trials reach the gate's `cost $X` line exactly once.
 
 ### Tests
-- `test/paid-report-cost.test.ts`: pricing arithmetic, streamed dedupe, `caseCost`, `recordE2E`'s `cost_case_id`, a two-case shard whose label-named records bind by cost without changing the failed record, class or model. `test/paid-report-census.test.ts`: a record-less trial's streamed cost reaches the trial and the verdict total once. It also prices a PTY session, its inline sidechains and subagent files once per message id, leaves a foreign session, a missing or unreadable transcript or an unpriced model unknown, and claims only the one new transcript for a launch's cwd. `test/helpers/claude-pty-runner.launch.unit.test.ts`: a real launch prices the transcript it created without adding an argument, and an opted-out launch prices nothing.
