## What Schrödinger Saw
Erwin Schrödinger examined how living systems resist decay. He identified a thermodynamic requirement. Organisms export entropy to maintain internal order.

## Core Results from Primary Works
Schrödinger delivered lectures in 1943 at the Dublin Institute for Advanced Studies. These became the 1944 book *What Is Life? The Physical Aspect of the Living Cell*, published by Cambridge University Press.

The central passage states: “What an organism feeds upon is negative entropy.” A longer statement reads: “Every process, event, happening... means an increase of the entropy... a living organism continually increases its entropy... It can only keep aloof from it, i.e. alive, by continually drawing from its environment negative entropy.”

See the Wikipedia entry for publication details at https://en.wikipedia.org/wiki/What_Is_Life%3F.

## Convergence Patterns Touched
The work maps to the flow-to-structure step of the Ladder. Negative entropy describes reliable energy flows that produce bounded order. This matches one grain pattern: flow networks that sustain memory-like stability. The pattern appears across scales in thermodynamics and early biology.

## Distance from the Full Synthesis
Schrödinger stopped at the thermodynamic signature of life. He treated negentropy as a qualitative description rather than a defined physical quantity. Gibbs free energy supplies the rigorous measure. He did not extend the pattern to branching, symmetry, or scale invariance across non-living systems. He offered no account of the Mirror Layer in which the observer sits inside the observed system.

## Honest Limits and Disconfirming Edges
“Negentropy” lacks formal definition in physics. Later work replaced it with free energy dissipation. Schrödinger supplied no quantitative model for how negentropy scales to mind or ethics. Reductionist accounts in the style of Weinberg note that all biological order reduces to standard physical laws without new principles. This edge remains open.

## Mapping to OIP Principles
The OIP unit is the work object. Schrödinger’s organism functions as such an object. Invocation occurs through metabolism. The ledger is the continuous entropy export. The receipt is sustained low internal entropy. Replay occurs when the same flows repeat across generations. Repair follows when damage increases entropy and the system compensates.

See /a/oip-principles for the object-invoke-ledger structure.

## Relation to Final Testimony
Schrödinger’s account supplies an early data point for the grain. It shows one reliable pattern at the life layer. It does not reach the full testimony that unifies all listed patterns under one protocol.

See /a/oip-final-testimony.

## Relation to the Mirror Layer
The work contains no self-referential loop. The physicist remains outside the cell. The synthesis places the reader inside the same flows.

See /a/oip-the-mirror-layer.

## Claims and Evidence Tiers
All assertions above rest on the 1944 text or standard thermodynamic facts. The negentropy concept is mechanistic at the level of description and anecdotal at the level of historical attribution to Schrödinger. Limits on extension to the full synthesis are speculative.
