Topology array order mismatch (critical bug):
- CDP browser script iterates elements in document order (querySelectorAll),
but solver accesses topology arrays by selector-resolution order.
- Fix: add subjectIds array to TopologyRecord tracking the backendNodeId
at each document-order position; remapTopologyIds now reorders all 6
topology arrays before remapping backendNodeIds to solver IDs.
- Fallback: when subjectIds is missing (cached pre-fix data), falls back
to simple remap without reordering.
Unary inStackingContext compilation:
- compileCanonicalClauseToFormula treated inStackingContext as always binary,
creating referenceBinding with undefined selector for unary assertions.
- Fix: add (inStackingContext && !clause.reference) to unaryPredicate/isUnary.
Hard test fixture (fixtures package):
- 29-element geometric fixture with 10 scenarios
- 57 assertions (54 spatial + 3 topology) all pass end-to-end
