## What Weinberg saw
Steven Weinberg pursued the fundamental laws of particle physics and cosmology. He unified the electromagnetic and weak forces. He supported the search for a final theory that explains all forces and particles from simple principles.

Core result: the Standard Model Lagrangian compresses vast data into equations of roughly 10,000 characters. Higher phenomena follow from those equations plus initial conditions.

## Primary works and passages
*Dreams of a Final Theory* (Pantheon, 1992). Chapter "Two Cheers for Reductionism" states: reductionism holds that "all of nature is the way it is because of simple universal laws, to which all other laws may in some sense be reduced."

Weinberg distinguishes grand reductionism (laws reduce) from petty reductionism (things reduce to parts). He argues that asking "why" repeatedly leads to fundamental laws.

## Convergence patterns touched
Weinberg addressed compressibility of physical law. This matches one GRAIN element: laws admit short descriptions across scales.

He addressed derivation of regularities from micro-laws under sufficient computation.

## Distance from the synthesis
Weinberg supplies no support for directional flow in the Ladder. He supplies no support for ontological emergence. He supplies no support for memory or mind arising as new structural layers with independent causal power.

His position functions as boundary. Emergence counts as epistemological only.

## Honest limits and disconfirming edges
No primary passage asserts grain-like patterns or Ladder progression. Weinberg explicitly places pride of place on fundamental laws over emergent descriptions.

A reductionist objection of this type remains live: given complete micro-laws and computation, higher regularities derive without remainder. This edge stands unrefuted by the synthesis.

Sibling article /a/oip-the-ladder carries the directional claim that Weinberg rejects. Sibling article /a/oip-principles carries the emergence node that Weinberg treats as non-ontological. Sibling article /a/oip-final-testimony records the boundary status of this view.

## Claims
- Claim c1: Weinberg unified electromagnetic and weak forces in 1967. Tier: human. Source: his PRL paper.
- Claim c2: *Dreams of a Final Theory* (1992) presents grand reductionism as laws reducing to simpler universal laws. Tier: anecdotal.
- Claim c3: Weinberg holds that higher-level regularities derive from micro-laws given sufficient computation. Tier: mechanistic.
- Claim c4: Weinberg assigns no ontological status to emergence. Tier: anecdotal.
- Claim c5: The synthesis receives no convergence from Weinberg on Ladder directionality. Tier: speculative.
