How the evidence informs this component

The gate asks whether the proposed response addresses the diagnosed cause. The multi-barrier account and the OLPC outcome counterexample explain why a visible input is not enough. They justify causal questioning; they do not directly validate this gate as an effectiveness instrument.

Follow the connections

Model → Master research themes → Themes → Categories → Descriptive codes → Evidence

Master research themes group the connected recorded themes. Master theme, theme, and category definitions are explanatory reading guides. Code definitions reproduce the codebook. Master grouping is a browsing aid. Branches preserve each code’s exact taxonomy; they do not imply a causal or chronological sequence.

5 distinct works in the focused alignment

Wider quoted source material · 230 passages from 156 reference entries

These are the stored quotations attached to this component’s 5 aligned descriptive codes. They broaden the material available for inspection; each passage is not automatically a separate confirmation of every model requirement. The focused argument and element-level alignment remain explicit below.

Trace 1 element through codes, categories, themes, and sources

Every code link opens its quotation, source, locator, recorded category, and recorded theme. The final alignment to the model is explained in the rationale column.
