D06-F04-A13 · LEVEL 2 GUIDED LAB · SYNTHETIC DATA

Mat Hold

Does a gapped, contained pause preserve the original trend structure before continuation? 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

long trend candle -> gap -> shallow multi-candle pullback above support -> continuation breakout

Availability rule

The label becomes available only after the final candle in the selected pattern has closed; prior-trend context must use observations available before that close.

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.
