R7b batch 4 #3 (docs/design/scala-kernel-port-checklist.md is the authoritative quirk list). The third vendored-grammar-C language and the biggest grammar in the tree (35MB parser.c): the vendored wasm is tree-sitter/tree-sitter-scala master@0aca5d0a6f — a post-v0.26.0 generation sync that is not a release (the 0.26.0 crate is 30 states BEHIND, so a crate pin would be a silent downgrade). NO wasm change: production has parsed with this exact revision since #91 — the kernel-grammar-parity row (ABI 15, 26,650 states, 32 fields, id-by-id tables) is the whole alignment proof. Preserved bug-for-bug (all probe-pinned): the leak-through asymmetries — extension methods mint NO nodes (first def's body calls leak to the enclosing scope, later defs invisible, and the braced form resolves its body field to the `{` TOKEN via first-match-wins field lookup → whole extension invisible); anonymous `new T { … }` template_body members leak to the enclosing scope (findAnonymousClassBody misses template_body); the bodied-vs-bodiless class asymmetry (bodiless headers walk class_parameters → default-value calls emit FROM the class; bodied ones never see them) — plus first-segment import names (`import com.example.C` → `com`), the val/var hook keyed on the enclosing-definition NODE TYPE (object vals → constants/value-ref targets, class/trait/enum/given vals → fields) with consumed initializers, every def routed through extractMethod with the top-level function fallback, nested defs in bodies minting NOTHING (the inverse of kotlin) while body-local classes extract fully, curried signatures keeping only the FIRST parameter list (type params win the `parameters` field), enum cases positioned at the CASE node with invisible params/extends tails, extends with-chains via scalaBaseTypeName, `@deprecated(args)` decorates, the #750 capitalized-chain re-encode (`WidgetS.create().render`), literal-receiver silence, static-member reads AND writes, infix invisibility, `derives` silence, scaladoc retention with the CRLF `\r` pin, full value-reference machinery (shadow prune, last-wins same-name targets, `$X`/`${X}` interpolation reads), and SCALA_SPEC fn-refs (bare ids + postfix eta unwrap + varinit, var-init non-capture). Gates: parity sweeps first-run 0-diff on os-lib/cats/scala3-compiler-src/ scala3-library-src — 1,935 clean files byte-parity, deferrals 0/15/57/116 matching the survey's predictions exactly (scala-3's PHANTOM hasError files — flag-true, zero ERROR nodes, capture-checking `^` — defer on the FLAG); full-init dumps byte-identical ×3 (os-lib, cats, scala3 whole-repo 950,889 dump lines); kernel-scala-parity suite (9 fixtures + 9 in-memory CRLF variants incl. Scala-3 indentation through the external scanner + phantom/real-error defer pins + first-segment/namespace/value-ref pins); full suite 2,669 green ×3 with CODEGRAPH_KERNEL_EXPECT=1 (kernel-scaffold's stays-wasm example moved scala → pascal). DEFAULT_ROUTED += scala (19 langs). Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
