D08-F01-A11 · LEVEL 2 GUIDED LAB · SYNTHETIC DATA

Fractal Support and Resistance

Which swing levels are actually knowable after causal pivot confirmation? Walk the evidence clock one stage at a time. This lab teaches the publication contract; it does not simulate returns, platform parity, or trade performance.

Selected expression

confirm pivot high/low only after r right-side bars; carry the latest confirmed level forward

Availability rule

A level derived from a prior session becomes available only after that source session is final; a confirmed pivot becomes available only after its declared confirmation lag.

Verified synthetic fixture

This lab is paired with datasets/implementation-fixtures.json: 96 deterministic, oldest-to-newest observations spanning oscillating, rising, and moderating regimes. It is teaching data—not market history or predictive evidence.
