json parity dashboard

Differential survey of @knowvah/dot-engine render(g, 'json') vs the native dot -Tjson oracle over the SVG-conformant corpus set, sorted by input size. -Tjson (not -Tjson0) is the oracle: the port structurally emits the doXDot=true shape ("_draw_": [] present on every node/edge — see the AD note atop test/golden/compare-json.ts). Semantic comparison (draw-op arrays at ±0.01, colors/fonts canonicalized, positional strings numeric-tolerant — see test/golden/compare-json.ts). Regenerate: npx tsx test/corpus/json-walk.ts --survey && npx tsx test/corpus/json-dashboard.ts.

Summary

• Oracle: dot 15.1.0 (-Tjson) · corpus: ~/git/graphviz/tests
• Walked (conformant SVG set): 905
• json-conformant: 903 (99.8%)
• diverged (tracked, will-fix): 0 · accepted (documented, won't-fix): 2
• port-error: 0 · timeout: 0 · oracle-error: 0 (excluded from scoring)

json-conformant (903)

Port json is conformant with the oracle: every object/attr/draw-op matches, numeric payloads within ±0.01 and canonicalized colors/fonts/text equal.

Conformant ids (903) are omitted for brevity — the full roster is in json-parity.json.

Tracked diverged (0) — worst-first

id	opClass	delta	rationale
share-Latin1	node:label / ldraw T.text [mixed-encoding]	0	Input is Latin-1 with NO charset declaration, so the bytes are invalid UTF-8. Native dot's -Tjson then emits a MIXED-ENCODING document: attribute values (e.g. node label) are echoed as RAW Latin-1 bytes (0xe1 0xe2 ... unconverted), while the DRAWN label text (ldraw T op, via make_label) is UTF-8 (0xc3 0xa1 ...). No single decode reads both halves correctly: Latin-1 recovers the attribute but mojibakes the text, UTF-8 does the reverse (and the attribute bytes are not valid UTF-8). The port decodes the input once (utils.c latin1ToUTF8 fallback) and is internally consistent valid UTF-8 on BOTH surfaces, so it cannot reproduce the oracle's split encoding. A4 class: the oracle output is an encoding bug; the port declines to emit invalid/mixed-encoding JSON. The DECLARED charset=latin1 case (graphs-Latin1/b60) IS handled via the stoj double-encode fix; only the UNDECLARED-charset case is irreducible.
windows-Latin1	node:label / ldraw T.text [mixed-encoding]	0	Identical mechanism to share-Latin1: undeclared-charset Latin-1 input makes native -Tjson emit raw-Latin-1 attribute bytes alongside UTF-8 drawn text (mixed, invalid). The port's consistent-UTF-8 output cannot match both halves. A4 class.

2095_1	edge:1083->1084#0/draw/op[1].b[0]	66.11999999999898	A1 irreducible (proven by injection A/B 2026-07-24): circo getRotation's closest-node selection (circpos.c:79-91) is an exact-tie knife edge for this graph's three copies of a symmetric 5-node block — the cut vertex and its mirror node are equidistant from the rotated origin in real arithmetic. V8's trig chain yields an exact FP tie (both 1.9333108975227196) so strict < keeps the neighbor (rot=0); Apple libm gives the neighbor +1 ULP so the mirror wins (rot 0.15/0.09/0.03 rad), rigidly rotating 3 blocks / 55 nodes by up to 5.2deg / 66pt. Injecting libm's ~2-ULP y asymmetry into just the 3 cut vertices makes the port match the oracle EXACTLY (2197 diffs -> 0 at 0.01): every port stage downstream is exonerated. Same class as the twopi 1855 radial mirror.
