decrements `pathfinding_remaining_route_steps`, so origin minus target is the route-step distance used
by M006/007/015.
The formerly unnamed `G[0xc6077]` stride-27 table closes the other half of that pathfinding ABI. It is
the reserved `1000 × 27` `selected_movement_route_steps` grid, not another search surface. MVRTN,
FIELD, and SETROUTE each clear all 27,000 cells. SETROUTE begins at `map_target_tile_x/y`, copies the
matching `pathfinding_remaining_route_steps` value, then walks the four `cardinal_tile_delta_x/y`
neighbors until it finds the cell whose score is one greater; it copies that score and repeats until
reaching the acting entity. The result is a one-cell-wide monotone route from actor to destination.
FIELD reads that trail both to draw direction-specific route markers and to drive movement along
successive scores. SELACT checks whether an action target follows movement, while every provider from
RTN_M002 through RTN_M018 tests its candidate endpoint for a nonzero selected-route cell. Across the
corpus the grid has exactly 51 two-dimensional lookups and five clears in 21 scripts. INIT2 proves the
shared cardinal vectors as `[0, 0, -1, 0, 1]` for X and `[0, 1, 0, -1, 0]` for Y. The target coordinate
pair is broader than routing: 55 scripts also pass scripted map locations through it to LOOK, which
centers the battlefield camera on the selected tile.
`movement_steps` now carry these selector-scoped semantic fields beside the original
`movement_parameter_1..4`, and top-level `movement_provider_parameter_schemas` records the reusable
mapping, target-selection rules, zero/unwritten behavior, and authored fields proven unread by their
