R7b batch 4 #4 — the FINAL R7b language (docs/design/dart-kernel-port-checklist.md is the authoritative quirk list). The fourth vendored-grammar-C language, with a twist: production dart resolved its wasm from tree-sitter-wasms, whose dart dependency is an UNPINNED github:UserNobody14/tree-sitter-dart — a routine dependency update would have silently changed dart's grammar. This PR byte-copies the shipping 0.1.13 artifact into src/extraction/wasm/ (VENDORED_WASM_LANGS += dart) and compiles the same-commit (d4d8f3e337d8) parser.c/scanner.c in the kernel — table identity proven by the kernel-grammar-parity row. crates.io tree-sitter-dart is the nielsenko fork (different lineage) — rejected. The center of gravity is THE SIBLING-BODY DOUBLE-WALK, reproduced bug-for-bug: dart attaches every function/method body as a NEXT SIBLING of its signature, and the TS walkers consume each body TWICE — once via resolveBody (attributed to the function/method) and once via the enclosing generic walk (attributed to the file/class). Duplicate local-function nodes with the SAME id under different parents, duplicated calls/instantiates refs, and file/class-attributed fn-ref twins all emit in the exact observed interleave (a dedicated fixture pins the duplicate-id rows; the bloc kind-census spot-check pins the counts). Also preserved (probe-pinned): the extractBareCall selector matrix (the first callTypes=[] language — cascades completely invisible, `?.` encodes like `.`, the `ConfigT.load()` calls+references double emission with no callee-of-call skip, capitalized-chain `Foo.create().run` re-encode, const-object callee names); the constructor hooks (unnamed ctor skipped, named ctors/factories renamed to the CTOR name with the class as returnType, `@override (T) m()` record-misparse rescued by class-name validation); operator methods minting `method "<anonymous>"`; static_final_declaration constants via the visitNode hook while instance fields mint NOTHING; the prefixed-return-type prefix bug (`other.OtherClass f()` → returnType `other`); enum `with` mixins silent vs `implements` working; anonymous extensions named after the ON type; deferred imports invisible; named-argument callbacks NOT fn-ref-captured (the Flutter `onPressed:` idiom — future accuracy PR, TS-side first); `async*`/`sync*` NOT async; value-refs with the LIVE dart sibling-body pull and the `$X`-vs-`${X}` interpolation asymmetry; dartdoc kept in all three comment forms with the annotation-broken chain. Gates: parity sweeps first-run 0-diff on shelf/bloc/flutter — 5,815 clean files byte-parity, deferrals 10/21/1341 ≈ the survey's 10/21/~1340 (both-arm grammar reality: empty object patterns — the sealed-class idiom — and unnamed `library;` dominate; --max-deferral 0.3); full-init dumps byte-identical ×3 (shelf 7,959 / bloc 40,026 / flutter 1,855,319 dump lines); bloc per-kind node census identical across arms (the double-walk duplicate rows survive the store identically); kernel-dart-parity suite (7 fixtures + in-memory CRLF variants + double-walk duplicate-id pin + generated-file skip pin + two defer pins); full suite 2,688 green ×2 with CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += dart (20 langs — R7b COMPLETE). Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
