Stars

Organic, confidence high

Bursts

• Feb 27, 2025 to Mar 7, 2025: about 68 more stars than usual, peak 15 in one day, a spike that tapers off. We couldn't check for an outside explanation.
• Oct 17, 2025 to Oct 20, 2025: about 174 more stars than usual, peak 93 in one day, a spike that tapers off. Outside explanation: a jump in forks.

Anyone can buy stars for any repo; bursts alone don't prove the owner did.

• The star history looks organic.
