@ -225,6 +225,9 @@ Current pure planner status:
only after space exists, and orthogonal growth happens in the final phase.
- Same-axis size redistribution is handled as a single scale phase when the
exact validator proves adjacent windows stay non-overlapping.
- Nested size redistribution can use hierarchy metadata to decompose two-axis
resizing into parent-axis then child-axis scale phases, but only when the
source/target ancestor split depths give a deterministic order.
- Every produced plan is checked analytically for overlap over the full duration
of each phase before it is accepted. This solves the linear edge inequalities
for each pair of moving rectangles instead of relying on sampled frames.

groups can still use multiphase animation when another group falls back to
linear motion.
- Planner requests now carry per-window hierarchy metadata for source/target
parent, depth, sibling index, split axis, mono state, and transition kind.
The current planner records this information but does not yet use it to order
nested-container phases.
parent, depth, sibling index, split axis, nearest ancestor split depth per
axis, mono state, and transition kind. The current planner uses this for
parent-before-child scale ordering, but not yet for full nested move planning.
- Multiphase planning has a diagnostic entry point used by live fallback logs.
It distinguishes request validation errors, missing patterns, shrink-bound
rejections, invalid phase steps, and exact validation failures such as stale

- horizontal swaps shrink, move, then grow without overlap
- extraction from a stack creates space before moving the extracted window
- nested size redistribution scales the parent axis before the child axis
- nested containers do not produce simultaneous cross-axis motion
- interruption restarts only affected phase groups
- reversing direction produces equivalent motion in reverse
