A Claude Code statusline that measures real work time, SubAgent speedup, and code-churn pace — not just tokens and cost.

What makes it different

Five things set cc-tempo apart from the ~15 existing Claude Code statuslines on GitHub:

• ⏱ 2h 15m Active work time — parsed turn-by-turn from the transcript JSONL. Excludes user-idle gaps and waits on interactive tools (AskUserQuestion, ExitPlanMode). Cumulative api_duration_ms inflates under parallel SubAgents; this doesn't.
• [1.8×] Speedup ratio — API cumulative time ÷ active wall-clock time. Surfaces only when the ratio reaches 1.2, so when you see it, SubAgent parallelism is actually helping.
• /clear-resilient timing — PID-keyed /tmp accumulator; /clear inside the same claude process does not reset the clock. A new claude invocation starts clean. claude --continue inherits the dead PID's accumulated total.
• Quality: ▁▁▂▃▅▆▇█ ↑ Code-churn sparkline — 8-char velocity track of added+removed lines per tick, zero-separate + log₂ min-max normalized, with a trend arrow after three data points.
• 2 active Multi-instance detection — surfaces concurrent claude processes on the same project directory.

Plus the table stakes: 20-char context bar, cache hit rate, lines-per-dollar efficiency, git diff stats, and 5h/7d rate-limit gauges with reset countdowns.
