# Study 000M Methods

## Study Type

Longitudinal N=1 synthesis study built from previously completed archive outputs rather than from a new raw-data ingestion pass.

## Core Question

`Is ecological narrowing itself part of the compensation phenotype?`

## Source Basis

This study drew from the following completed packages:

- `000C` full-data exhaustive program analysis
- `000D` selective expression
- `000AB` integrated adaptation synthesis
- `000H` envelope support factors
- `000K` multi-mode adaptive envelope

## Main Evidence Families

### 1. Running Ecology Compression

Used yearly running-share and running-surface concentration values to test whether later successful running expression became more concentrated rather than more broadly distributed.

### 2. Flagship Window Ecology Contrast

Used early versus late flagship window context values plus hybrid overlap correction to test whether late running specialization remained a distinct ecological state after correction.

### 3. Support-Dependent Boundary Expression

Used October 2025 high-burden outside-context cases, April 2026 supported boundary expression, and `000K` mode structure to test whether successful expression required ecologically supportive states rather than broad environmental tolerance.

### 4. Conditioning Ecology Reorganization

Used hybrid-cardio corrections and integrated synthesis outputs to test whether the broader conditioning ecology simply simplified or was selectively retained in specific forms.

## Decision Logic

The study was judged against three competing readings:

- ecological change as incidental drift
- ecological change as descriptive but not explanatory
- ecological narrowing as part of the compensation phenotype

The strongest answer was determined by which model better organized:

- running-share concentration
- treadmill concentration inside running
- corrected hybrid-cardio context
- burden behavior at the ecological edge
- support dependence of successful expression
- multiple successful low-burden routes
