# Story 300: Show token cost badge on pipeline board work items

## User Story

As a project owner viewing the pipeline board, I want to see the total token cost for each work item displayed as a badge, so that I can quickly spot expensive stories at a glance.

## Acceptance Criteria

- [ ] Each work item on the pipeline board shows its total cost in USD as a small badge
- [ ] Cost is fetched from the token_usage.jsonl data via a new API endpoint
- [ ] Items with no recorded usage show no badge (not $0.00)
- [ ] Cost updates when the pipeline refreshes (e.g. after an agent completes)
- [ ] Expanded work item detail panel shows per-agent cost breakdown (coder, QA, mergemaster) with token counts

## Out of Scope

- TBD
