Structural Threat Infection Chain Hash
A content-independent fingerprint of the infection method: successive formats, internal objects and MITRE techniques from the initial file to each final payload.
STICH Path = the fingerprint (canonical chain with techniques)
STICH Shape = structure only
Only determinant branches produce STICH Paths.
