- Remove dead ternary in getPreferredEdges (always returned undefined; the
all-false object was never reached by Object.values().some(Boolean))
- Document why drawWithFeather descriptors zero the feather field in the
compositor (analytical renderer handles softness itself; zeroing prevents
a second JFA feather pass)
- Remove legacyType from V30→V31 migration (not consumed anywhere; a
down-migration can map type:"freeform" back to "custom" directly)
- Add V30→V31 test coverage: skip-guard branches, freeform passthrough,
elements without a masks array
- Add snap tests for vertical-edge (bottom) and uniform-scale handle paths
