sfdp imagemap (cmapx/imap) parity dashboard
Differential survey of @knowvah/dot-engine sfdp imagemap (cmapx/imap) output vs the native dot -K sfdp 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 sfdp && npx tsx test/corpus/parity-report.ts.

1447 | 88 | area[0].coords[1] | layout drift inherited from the sfdp xdot engine track: id diverged there with the documented accepted mechanism; imagemap re-emits the same layout as rounded hotspot coords. Journal 2026-07-24. |
1447_1 | 590 | area[0].coords[1] | layout drift inherited from the sfdp xdot engine track: id diverged there with the documented accepted mechanism; imagemap re-emits the same layout as rounded hotspot coords. Journal 2026-07-24. |
1879 | 2118 | area[0].coords[0] | A1 sfdp chaotic drift (2026-07-24): whole-layout basin divergence on a huge graph (maxDelta 7.6kpt), the documented sfdp spring chaos regime — same class as fdp 1879 (chaos proven by perturbation A/B on the fdp family; sfdp is the measured chaotic engine). |
2619_1 | 12 | area[1].coords[0] | A1 sfdp spring drift (diagnosed 2026-07-24): 6 nodes, positional drift 0.7-1.3pt — the documented chaotic-engine regime, mildly above the 0.5 bar on a small graph. Same class as the sfdp engine track's 232-id tail. |
2621 | 4961 | area[0].coords[0] | A1 iterative-solver drift (class) — membership computed from attribution-sfdp.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. See known-divergences.md#a1-drift-iterative-engines. |
