Observation

Published official-adjacent models disagree on pancake vs bowing-column initiation of the tower collapses.

Interpretation

Uncertainty inside the fire-and-impact family (H003), not automatically support for H004.

Source text

OBSERVATION: Two official-adjacent engineering stories differ on the initiation morphology. Alternative investigators note that if even the official camp changed morphology, the mechanism is less settled than press summaries imply.

This is not a demolition finding. It is a reminder that 'the official explanation' is a moving engineering product.

Hypothesis linkage

    Official-adjacent pancake vs bowing-column disagreement shows the fire family is not internally unique.
