Frame Report

ISAAC's own SOURCE_PATH_VIA_GOAL fine-tunes SOURCE_PATH_GOAL by naming an intermediate, passed-through waypoint. Rather than minting SOURCE_PATH_VIA_GOAL as its own MOTION-family schema, the waypoint gets its own thin schema — Test 6 over VALUE, sibling to SOURCE/GOAL, licensed the identical way (a frame whose LU denotes the via-point itself, independent of any one traversal, can ground here directly). Distinct from GOAL: a via-point is explicitly not the final position. SOURCE_PATH_VIA_GOAL itself resolves via multiple grounding (SOURCE_PATH_GOAL for the traversal + VIA for the named waypoint), the same device already used for entrar and REVOLVING_MOVEMENT (redesign_proposal.md §10.3).
