durability
bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal
- Shifts software development toward spec-first workflows that are auditable and repeatable.
- Bridges human intent and machine implementation by encoding requirements as executable artifacts.
- Provides a practical path for enterprises to ensure compliance, governance, and quality in AI-assisted coding.
under the hood
- CLI built around specify, /constitution, /plan, /tasks, and /implement commands.
- Works with multiple AI coding agents (Claude, Copilot, Cursor, Gemini, Qwen).
- Licensed under MIT, with maintained support from GitHub engineers.

- now 129k + 100k since first covered
curve is sampled from GitHub's star history, plus our own daily readings since we covered it; the dashed stretch is before we first covered it, the solid line since. figures at coverage are the numbers we printed then (approx.), current count is live.
understory
Output and attention are roughly in balance.
- output, commits & releases
- clout, star velocity
output = commits & releases; clout = star velocity, both 0 to 100 monthly indices; the gap where output runs above clout is the understory. The understory →
