Use the component sync result only as a geometry proposal when settling
reflections and swapped placement. Correct existing shapes without pulling
pending library content, styles or structure into a transformed copy.
Keep path geometry and the primary action's exact undo/redo group.
Generate source transforms, letters and all twelve text style units with
separate source histories and explicit consumer acceptance. Add dropped
source-edit controls and portable/frontend regressions for the accidental
pull. Register the new portable namespace in the JavaScript runner.
The complete original program and both reductions pass unchanged.
Common JVM passes 1,919 tests/31,313 assertions. Full JS passes
1,845/29,770; the newly registered source namespace adds 5/135 passing
checks. Frontend passes 1,566/11,119, backend 1,610/8,104 and exporter
14/32. Lint and formatting pass; browser ShapeProxy replay passes.
No golden data changes.
Benchmark ratios against the unchanged baseline: mains 10/100/1000
0.57/0.65/0.61, levels 0.52, chain 0.51, library 0.52, many shapes 0.47,
variant switch 0.60. No regression flag.
