## Content

Legal analysis of California AB 316 (signed by Governor Newsom October 13, 2025; in force January 1, 2026).

Key provisions:
- Prohibits any defendant who "developed, modified, or used" AI from raising the defense that the AI autonomously caused the harm
- Applies to the entire AI supply chain: foundation model developer → fine-tuner → integrator → enterprise deployer
- Does NOT create strict liability: causation and foreseeability still required by plaintiff
- Explicitly preserves other defenses: causation, foreseeability, comparative fault
- Does NOT apply to military/national security contexts

The "autonomous AI" defense that AB 316 eliminates: "the AI system made this decision on its own, without my meaningful participation or control; therefore I should not be held liable."

Baker Botts analysis: AB 316 forces courts to ask "what did the company build?" rather than accepting "the AI did it" as a liability shield. This aligns precisely with the architectural negligence theory: defendants can no longer hide behind AI autonomy; they must defend the design choices that enabled the AI behavior.

Supply chain scope: "This language encompasses the entire AI supply chain — the foundation model developer, the company that fine-tunes or customizes the model, the integrator that builds it into a product, and the enterprise that deploys it." Each node in the chain loses the autonomous AI defense for its contribution.

## Agent Notes

**Why this matters:** AB 316 is the strongest example of substantive governance convergence found in any Leo research session. Unlike HITL requirements (form without substance) or Congressional accountability demands (information requests without mandates), AB 316 creates an enforceable, in-force legal change that eliminates the primary accountability deflection tactic.

**What surprised me:** That this is a California state law — exactly the level of governance the Trump federal preemption framework was designed to override. AB 316 survived because it's narrowly framed (removes a specific defense, not a general AI duty of care) — harder to preempt than broad "AI safety standards."

**What I expected but didn't find:** Federal preemption analysis of AB 316 specifically. The Trump AI Framework preempts "ambiguous content liability standards" — AB 316 is procedural (removes a defense), not substantive (creates a duty). This distinction may be AB 316's protection against federal preemption.

**KB connections:** Directly pairs with Nippon Life v. OpenAI (architectural negligence theory). AB 316 + Nippon Life is a compound mechanism — removes deflection defense + establishes affirmative design defect theory. Connects to the governance convergence counter-examples for Belief 1.

**Extraction hints:** Two claims: (1) "California AB 316 eliminates the autonomous AI defense across the entire AI supply chain, establishing that AI-caused harm is attributable to system design decisions rather than AI autonomy — the first in-force statutory codification of architectural negligence logic." (2) "AB 316's procedural framing (removes a defense) rather than substantive framing (creates a duty) may protect it from Trump AI Framework federal preemption targeting 'ambiguous content liability standards.'"

**Context:** California has historically led US state-level AI governance (alongside Washington and Illinois). AB 316 was signed while federal AI governance remains minimal. The law became effective January 1, 2026.

## Curator Notes (structured handoff for extractor)

PRIMARY CONNECTION: design liability / architectural negligence convergence mechanism — strongest substantive governance counter-example to governance laundering thesis

WHY ARCHIVED: AB 316 is in force, applies to entire AI supply chain, and eliminates the primary accountability deflection tactic — this is the most concrete example of mandatory AI governance working where voluntary mechanisms failed

EXTRACTION HINT: Extract two claims: the AB 316 mechanism itself (what it does) AND the scope limitation (doesn't apply to military/national security — which is exactly where governance matters most in the governance laundering pattern)
