neato imagemap (cmapx/imap) parity dashboard
Differential survey of @knowvah/dot-engine neato imagemap (cmapx/imap) output vs the native dot -K neato oracle (test/corpus/map-walk.ts), semantic comparison per docs/conformance.md (±0.01 deterministic tolerance, ±0.5 for the iterative engines). Regenerate: npx tsx test/corpus/map-walk.ts neato && npx tsx test/corpus/parity-report.ts.

2621 | 5044 | area[0].coords[0] | A1 iterative-solver drift (class) — membership computed from attribution-neato.json: injecting the oracle's pre-routing node positions makes the port reproduce the oracle with zero diffs, so the residual is the solver's fp-chaotic positions alone.
