fix(kernel): guard the native walkers against stack overflow and defer deep files to wasm (#1581)
A C/C++ (or any other kernel-routed) file with extremely deep nesting — clang's 16,384-brace `parser_overflow.c`, fuzzer corpora — parsed fine (tree-sitter is iterative) and then overflowed the native stack of the kernel's recursive walker. A native overflow is uncatchable: the parse worker is a thread of the `codegraph` process, so the SIGSEGV took the whole indexer down with no message, no partial index and no per-file fallback. Worker threads get Node's 4 MiB default stack; the 8 MiB main thread only moved the cliff (100k levels still died), so a bigger `resourceLimits.stackSizeMb` was never a fix. The walkers now guard their own recursion against the CALLING THREAD's real stack bounds (`codegraph-kernel/src/stack.rs`: glibc/musl `pthread_getattr_np`, macOS `pthread_get_stackaddr_np`, Win32 `GetCurrentThreadStackLimits`; one thread-local load + one compare per recursive entry, inserted by the `stack_guard!` macro at all 150 self-recursive / on-cycle walker functions). Within 256 KiB of the limit the walk stops descending and latches a flag; `stack::run_guarded` turns a tripped walk into the kernel's existing `defer:` routing signal, so the file takes the wasm path — whose walker catches its own JS `RangeError` per file — and lands as a partial result with a recorded parse error while the rest of the repository indexes normally. Platforms without a bounds query fall back to a fixed descent budget that is safe on any stack ≥ 2 MiB. No Worker stack bump; no new crates beyond `libc` (already in the lock file transitively). Validated: the reporter's `deep.c` inside a default 4 MiB worker goes from rc=132/139 to a clean `deferred` exit; `codegraph init` on a repo holding it exits 0 with the file recorded; 60k-deep expressions in every default-routed language survive on the main thread and in a worker; Rust unit tests drive the walkers on a 1 MiB thread; all 15 existing kernel parity suites unchanged; index wall-clock on express and redis within run-to-run noise with identical node/edge counts; Linux verified in Docker (node:22-bookworm, glibc bounds path).

feat(kernel): R7b Lua+Luau walker — one lua module, vendored-grammar-C lua v0.4.1, tree-sitter-luau 1.2.0 pin, both default-routed (#1384)
R7b batch 4 #2 (docs/design/lua-luau-kernel-port-checklist.md is the authoritative quirk list). ONE walker for both dialects (ccpp precedent) — the differences are exactly four: luau's type_definition aliases, the `export `-slice isExported hook, the return-type signature suffix, and the grammar handle. Grammar prep is kernel-side only, no wasm change: lua is the SECOND vendored-grammar-C language (the vendored wasm is the v0.4.1 tag, a revision not on crates.io — tag artifacts compiled via build.rs, shas pinned); luau is a plain crate pin =1.2.0 whose tarball is sha-identical to the tag (the swift tag≠crate divergence does not recur). Grammar-parity rows replace the bump gate entirely. Preserved bug-for-bug (all probe-pinned): the require/visitNode-hook ASYMMETRIES (top-level requires — including inside top-level if/for/while — mint import nodes while the identical body-level statement emits `calls "require"`; top-level `local x = foo()` initializers are invisible while global `x = foo()` calls emit), the BFS string-win inside require args (`require(script:WaitForChild("Kid"))` → import Kid) and Roblox instance paths, receiver-QN methods (`M.sub.deep::chained`, `_G::installed`, stack-QN nested globals like `render::leakedGlobal`), the raw-text callee world (colon forms with `self` never stripped, bracket callees, newline-glued chains byte-verbatim, the `(handler)` paren-conversion), LUA_SPEC function-as-value capture with the `M.cb = cb` param-storage skip and first-occurrence dedupe, LuaDoc `---` keeping a leading `- ` plus `--!strict` joining docstring chains (block-comment docstrings keep interior CRLF bytes), variable nodes at the IDENTIFIER with positional value pairing, duplicate same-(kind,name,line) ids, and the lua↔luau isExported wire divergence (lua functions: flag absent; luau functions: present-false; methods: absent in both; variables: present-false in both; `export type`: true). Gates: parity sweeps first-run 0-diff on kong/lazy.nvim/lua-resty-core (lua) + lune/Fusion (luau) — 1,734 clean files byte-parity, deferrals 1/0/0/3/8 matching the survey's both-arm predictions exactly (kong's 1 = a deliberately invalid fixture; luau's = grammar-inherent generic type packs and default type params); full-init dumps byte-identical kernel-vs-wasm ×4 (kong 157,650 dump lines); kernel-lua-parity suite (both torture fixtures + in-memory CRLF variants + glue-chain, duplicate-id, and cross-dialect defer pins + kernel-arm wire-flag pins); full suite 2,647 green ×2 with CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += lua, luau (18 langs). Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

feat(kernel): R7b R walker — rlang module, tree-sitter-r 1.2.0 crate pin, r default-routed (#1383)
R7b batch 4 #1 (docs/design/r-kernel-port-checklist.md is the authoritative quirk list; survey + probe record therein). The lightest-shared-surface, heaviest-hook port: languages/r.ts works entirely through the visitNode hook (every type list empty except callTypes:['call']), so the walker is a file node + a faithful hook transcription + the generic extractCall + pre-order recursion — four shared machineries (value-refs, static-member reads, type annotations, fn-ref capture) are dead by language gates and stay dead. Grammar prep is the first true no-op of the arc: the crates.io tree-sitter-r 1.2.0 tarball ships parser.c AND scanner.c sha-identical to the r-lib v1.2.0 tag the vendored wasm was built from — crate pin only, no wasm change, no bump gate; kernel-grammar-parity gains the r row (ABI 14, same-revision). Preserved bug-for-bug (all probe-pinned): calls "return" on every return(x) (named node in v1.2.0), the import quintet's silent dynamic-arg consumption vs class/generic fall-through asymmetry, library(help = pkg) importing the named arg, class-idiom variable suppression by callee name, chained/right- assign/precedence-ghost gaps, env$fn body-leak-to-file, raw-text callees verbatim (pkg::fn, obj$meth, "strfn" quotes kept, (handler) conversion), duplicate same-(kind,name,line) ids, roxygen dropped entirely, UTF-16 columns/slices. Gates: parity sweeps first-run 0-diff on AnomalyDetection/dplyr/ggplot2/ shiny (838 files; deferrals exactly 0/0/0/1 — the 1 is the moustache- template pseudo-R file, both-arm) — kernel-parity.mjs gained lowercased- extension matching so .R files sweep (matches detectLanguage routing); full-init dumps byte-identical kernel-vs-wasm on dplyr/ggplot2/shiny; kernel-r-parity suite (torture fixture + in-memory CRLF + BOM variants + defer pin + kernel-arm quirk pins); full suite 2,638 green ×2 with CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += r (16 langs). Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

feat(kernel): R7b Kotlin walker — kotlin module, vendored-grammar-C build, kotlin default-routed (#1382)
Sixth R7b port — the T1½ batch finale. Checklist-first recipe
(docs/design/kotlin-kernel-port-checklist.md, 1,121 lines, dist-extractor
ground truth); parity passed FIRST RUN on all three repos.
THE NOVEL MECHANISM — vendored-grammar-C (the §4 tracker's prescription,
first use): the crates.io tree-sitter-kotlin 0.3.8 pins `tree-sitter >= 0.21,
< 0.23` (the kernel links 0.25) and tree-sitter-kotlin-ng is a DIFFERENT
grammar (8 fields vs 0, renamed kinds — extractor-breaking), so no crate dep
is possible. The fwcd 0.3.8 tag's sha-matched parser.c + scanner.c are
vendored into codegraph-kernel/grammars/kotlin and compiled by build.rs (cc),
exposed via tree-sitter-language::LanguageFn. The wasm re-vendor is
behavior-NEUTRAL (0 CST/error disagreements across 1,984 gate-repo files;
old-vs-new full-init dumps byte-identical ×3) — a reproducibility re-vendor,
ABI stays 14.
Walker firsts: extension-function receivers (getReceiverType →
`WidgetK::extend` QN OVERRIDE with no package prefix, the qualified-receiver
`com::qext` first-segment bug, and the owner-contains fallback that excludes
`interface` kinds and is source-order dependent) and extractModifiers
(expect/actual platform modifiers → the node DECORATORS wire field on every
created node — the KMP synthesizer's feed, incl. `actual typealias`).
Preserved bug-for-bug: the FIELD_COUNT-0 dead cluster (no signatures, ZERO
type-annotation refs), hook-consumed property initializers emitting nothing
(incl. `by lazy {}`), the bodiless-vs-bodied class header asymmetry, enum-
entry bodies being invisible, KDoc never a docstring AND chain-breaking,
comment-gluing into import/package extents, `@Anno(args)` emitting nothing
while `@Marker` decorates, zero instantiates refs, the paren-then-lambda
`trailing()` garbage callee, text-includes visibility/suspend false
positives, and the packaged-file value-ref target drop. The fun-interface
misparse-recovery hook is DEFER-SHIELDED (every such file has_error) and
deliberately not ported. The swift-sweep lesson pre-applied: the shared
`assignment` shadow-prune case is implemented alongside the
property_declaration case.
Gates: sweeps 0-diff okio 299/322, okhttp 531/580, kotlinx.coroutines
1031/1082 (deferrals exactly the predicted 23/49/51 — both-arm grammar
reality incl. PHANTOM hasError files with complete CSTs; the kernel trusts
the flag); full-init dumps byte-identical ×3 (46.5k/108.9k/92.3k lines); KMP
expect/actual synthesis IDENTICAL across arms (412 edges on
kotlinx.coroutines — the tracker's KMP validation); kernel-kotlin-parity
suite (torture reflowed off the phantom shapes + .kts script + CRLF variants
+ fun-interface and phantom defer pins) + kotlin grammar-parity row (the
C-build ↔ wasm table identity proof); full suite 2,633 green ×2 under
CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += kotlin (15 langs).

feat(kernel): R7b Swift walker — swift module, tree-sitter-swift 0.7.3 bump, swift default-routed (#1381)
Fifth R7b batch-3 port, checklist-first recipe (docs/design/swift-kernel-port-checklist.md, 1,056 lines — the largest of the arc, with a built-extractor-validated emission pin and a childForFieldName truth table). Grammar bump first, validated standalone: tree-sitter-wasms ^0.4.0 (ABI 13) → crate 0.7.3 — with a provenance twist: the wasm is built from the CRATE TARBALL's src/ (alex-pinkus keeps generated files off main and the 0.7.3-with-generated-files tag ships an older ABI-14 generation that can never sha-match; grammar.json rules are JSON-equal; the tarball is byte-for-byte what the kernel's cargo build compiles — table identity by construction). Older crates evaluated and rejected: clean-parse shapes are byte-identical on 0.7.3 (53-line CST battery diff, all inert), so an older pin buys nothing and loses the macro-era wins. Delta = error-set membership (63 old-error files parse clean: swift-testing #expect, #Preview/#GET macros, package access, typed throws — vapor 23.1%→9.3%; 21 NEW-only regressions in 3 probed construct classes) + two gate-found categories: docstring boundaries near #if directives (7 clean files, docstring-field-only — verified mechanically) and array-literal-callee call refs (2 refs, 1 file). Every hunk classified via the error-union rule + parked-ref↔edge ripple pairing. Walker (the arc's biggest) centers on the #1020 DEDICATED property branch: computed properties → property nodes with the getter walked under the property (SwiftUI body), static let/var → constant/variable, stored → field, decorator/type-annotation/@Siblings-attr-arg refs all attached to the ENCLOSING TYPE, stored initializer calls attributed to the class. Preserved bug-for-bug: the never-resolving 'parameter' field (zero param type refs, zero signatures), present-false isAsync, open→internal visibility, everything-is-extends inheritance (first type_identifier per specifier), no instantiates refs ever, subscript reads as `calls arr`, `defer` as `calls defer`, multi-case enum entries minting only the first case, /** */ block docs ignored AND chain-breaking, init/deinit/subscript minting no nodes with visitNode-routed bodies (calls → class, static reads → nothing), multi- segment extension resolveName, sugar extension names, the #selector shapes, and the value_argument label-forward skip. ONE fix found by the sweep (then pinned in the fixture + checklist): the shared `assignment` shadow-prune case is swift-live — declared-then-assigned `let X: T` prunes X as a value-ref target. Gates: sweeps 0-diff Alamofire 89/98, vapor 224/247, swift-nio 407/554 (--max-deferral 0.3 — swift error incidence is 9–27% on BOTH arms, structural; every deferral count matches the survey's table exactly); full-init dumps byte-identical ×3 (31.9k/20.7k/126.3k lines); the Alamofire census reproduces property=348 (the #1020 number) on the kernel arm; kernel-swift-parity suite (206-line torture + CRLF + the #if-between-enum- cases defer fixture) + swift grammar-parity row; full suite 2,626 green ×2 under CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += swift (14 langs). Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

feat(kernel): R7b PHP walker — php module, tree-sitter-php 0.24.2 bump, php default-routed (#1380)
Fourth and final R7b batch-2 port, checklist-first recipe (docs/design/php-kernel-port-checklist.md). Grammar bump first, validated standalone with the diff ENUMERATED + CLASSIFIED (unlike rust/ruby the php bump is NOT graph-neutral): tree-sitter-php ^0.22 (tree-sitter-wasms, 2023) → v0.24.2, the full HTML-interleaving `php` variant (the walker calls LANGUAGE_PHP, never PHP_ONLY) — crate pinned =0.24.2, wasm built from tag 5b5627f's checked-in php/src/parser.c + scanner.c + shared common/scanner.h (all sha-matched against the crates.io tarball, ABI 14→15). Old-vs-new full-init diffs decompose completely into: (1) the anonymous_class wrapper shape (anon-class nodes/methods re-shape — 2,532 rows), (2) grouped nested-clause skip (absent in the gate repos, fixture-pinned), (3) 32 formerly-erroring files parsing clean (monolog Level.php, symfony Request/Response with 8.4 property hooks), (4) a survey-missed category found at gate time: the 8.4 parenthesis-free `new X()->m()` chaining misparse fix (86 garbage instantiates refs disappear, precision-positive), plus resolution RIPPLE proven mechanically (every remaining ref-table flip pairs 1:1 with a resolved edge on the opposite side; node rows byte-stable outside 1/3/4). Walker (java.rs chassis + the php specifics) preserves bug-for-bug: the visitNode hook (const_declaration at ANY scope → bare `constant` nodes, values never walked; trait-use → implements refs WITH filePath via the ruby port's REF_FLAG_FILE_PATH wire slot), FIRST-namespace whole-file scoping (braced namespaces scope nothing; namespaced files DROP top-level const value-ref targets), the import trio (single/aliased/grouped incl. the nested-clause skip, include/require static-literal-only, `Foo\Bar::Baz` use refs), the call-encoding zoo (DOT-joined scoped calls, `this->prop.m` #1251 encoding, `Cls::factory().m` fluent with inner args dropped, nullsafe `?->` emitting nothing, unsuppressed literal receivers), interface multi-extends first-base-only drop, anon-class methods as file-level functions (top) or vanishing (in-body), property type-hints emitting no field refs, the final-modifier-as-type signature quirk, HOF-gated string callables (skipGate) + array callables, and the `name`-node value-ref reader. Gates: sweeps 0-diff monolog 217/217, laravel-framework 3007/3008, symfony 10726/10737 (13,950 files byte-parity; 12 deferrals = exactly the predicted genuinely-broken fixtures, ≈0–0.1%); full-init dumps byte-identical ×3 (16.1k/354.2k/702.8k lines); kernel-php-parity suite (torture + drupal .module + leading-HTML fixtures, CRLF variants, wire-flag pin, defer) + php grammar-parity row; full suite 2,622 green ×2 under CODEGRAPH_KERNEL_EXPECT=1.

feat(kernel): R7b Ruby walker — ruby module, tree-sitter-ruby 0.23.1 bump, ref-flag wire slot, ruby default-routed (#1379)
Third R7b port, checklist-first recipe (docs/design/ruby-kernel-port-checklist.md). Grammar bump first, validated standalone (the rust pattern): tree-sitter-ruby ^0.20.1 (tree-sitter-wasms, 2024-02) → v0.23.1 — crate pinned =0.23.1, wasm built from tag 71bd32f's checked-in parser.c/scanner.c (both sha-matched against the crates.io tarball; content bump, ABI stays 14). Old-vs-new full-init dumps: sinatra/jekyll byte-identical; rails = exactly the one classified hunk (the `recv&.!=` safe-nav operator misparse fix, `table_name.!` → `table_name.!=`, precision-positive). Walker (python.rs chassis + the six ruby divergences) preserves bug-for-bug: the importTypes:['call'] funnel (class-body DSL — attr_accessor, has_many, define_method incl. its block, sinatra route blocks — emits NOTHING at non-body scope), hook-handled module multiply-capture (nested modules re-scan their subtree per level after popping — `this.hooked` fn-refs from class AND module AND file), the sibling-scan visibility trio (bare `private` invisible; `private :sym`/`private def` poison all later defs; the inner def stays public), bare-call statements (do…end body_statement emits, brace-block block_body doesn't), `.new` instantiates with last-`::`-segment names, constant-receiver references refs, require/require_relative path refs (posix-normalized, `.rb`-suffixed, `Kernel.require` and interpolated-path quirks included), `=begin` docstring marker survival, and the reverse-order value-ref DFS. Wire v2: the hook's mixin `implements` refs carry `filePath: ctx.filePath` — the ONE extraction-ref denormalized field (php's trait-use refs share the shape). RefRow's first pad byte becomes a flags slot (REF_FLAG_FILE_PATH); decode re-attaches its own filePath parameter; KERNEL_ABI_VERSION 1→2 on both sides (mismatched dist/.node pairs degrade to wasm, as designed). Gates: sweeps 0-diff sinatra 147/147, jekyll 164/164, rails 3452/3452 (3,763 files, 0 deferrals — ruby error incidence 0.00%, any deferral = walker bug); full-init dumps byte-identical ×3 (7.2k/9.4k/375.6k lines); kernel-ruby-parity suite (torture + CRLF + wire-flag pin + defer) + ruby grammar-parity row; full suite 2,613 green ×2 under CODEGRAPH_KERNEL_EXPECT=1 (one unrelated mcp-initialize timing flake under parallel load, passes solo 3/3 ×3).

feat(kernel): R7b C# walker — csharp module, tree-sitter-c-sharp 0.23.5 pin, csharp default-routed (#1378)
Second R7b port, checklist-first recipe (docs/design/csharp-kernel-port-checklist.md; parity passed FIRST RUN again). No grammar bump — the #717 vendored wasm verified table-identical to crate 0.23.5 (ABI 15, STATE_COUNT 8053, node-kind + field tables); first port with no grammar-prep step. The #237 #if-blanking preParse stays TS-side via the existing route-point hoist. Walker preserves bug-for-bug: the single-namespace-node quirks (second namespace nests under the first, nested namespaces leave no trace, import refs hang off the namespace node), raw member-access callee texts (this./base./literal receivers, multi-line fluent chains) with unconditional chain re-encode, deliberate emission holes (property accessor/expression bodies, ctor initializers, delegates/events/ operators/indexers/local functions, top-level locals), garbage extends refs ((repo) primary-ctor args, BaseDto(Name) record bases, enum : byte), the alias- import moduleName quirks, nameof-as-call, CSHARP fn-ref spec (+= subscription, this.X bare-name form, argument layer, initializer lists), C# type-ref engine (nested-generic returnType failure included), and value-ref shadow pruning. Gates: sweeps 0-diff serilog 211/216 / Newtonsoft.Json 914/945 / jellyfin 2104/2105 (deferrals match the survey's per-repo predictions — both-arm #if damage; default --max-deferral 0.1 holds, no c/cpp exemption); full-init dumps byte-identical ×3 (14.0k/109.1k/210.8k lines); kernel-csharp-parity suite (torture ×3 + CRLF variants + 8 micro-pins + defer) + csharp grammar-parity row; full suite 2,608 ×2 under CODEGRAPH_KERNEL_EXPECT=1.

feat(kernel): R7b Rust walker — rustlang module, tree-sitter-rust 0.24.2 bump, rust default-routed (#1371)
First R7b language port. Grammar: tree-sitter-rust pinned =0.24.2 + wasm vendored from tag 77a3747 (parser.c/scanner.c sha-matched against the crates.io tarball), replacing the 2023 ABI-14 tree-sitter-wasms build — the bump alone is precision-positive on the wasm path (receiver-qualified instance-method resolutions replace ambiguous bare-name matches; node sections byte-identical on ripgrep/tokio). Walker mirrors the TS reference bug-for-bug per docs/design/rust-lang-kernel-port-checklist.md (survey artifact): dead-code isAsync, impl-pushes-no-scope, the impl-Trait-for-Generic<T> trait-receiver quirk, phantom const identifiers, use-binding triple emission, wildcard-use-emits-nothing, scoped-supertrait drop, chained-call re-encode gated on scoped_identifier, Rocket route macros body-only. Gates: parity sweeps 0 diffs — ripgrep 101/101, tokio 790/790, rust-analyzer 1217/1488 (271 deferrals are token-macro-table sources that error on BOTH arms — grammar-inherent); full-init dump-diffs byte-identical on all three (3,857 / 13,440 / 39,030 nodes); kernel-rustlang-parity suite (torture + CRLF + defer) in npm test; full suite green x2 with CODEGRAPH_KERNEL_EXPECT=1.

feat(kernel): R7a C/C++ walker — dual-lang ccpp module, preParse hoist, 7 new blanks, c/cpp default-routed (#1346)
Parity: 0 diffs on redis/git/fmt/protobuf/ALS sweeps; full-init dumps byte-identical on all five + linux at kernel scale (10.4M dump lines, same sha256 both arms). Linux 2c/6GB envelope: kernel-arm 19.1min vs wasm-arm 22.9min (parse 356s vs 435s) on a much richer graph (the new blanks recover error-swallowed code: git 2x nodes, linux kernel/+mm/ 3x). Deferral guard corrected by measurement (C/C++ error incidence 9-42%; --max-deferral flag); defer-reuse memo kills the 3x re-blank/re-parse cost deferred files paid.

feat(kernel): R5 — Python and Go ports, gates passed, default-on
Python (codegraph-kernel/src/python.rs) and Go (src/go.rs) join the native kernel, mirroring the wasm extractors bug-for-bug. Python: decorated_definition docstrings/decorators (decorates refs only for bare-identifier decorators — the call-kind quirk), function-in-class → method, module-level assignments always extract as variable, from-import per-name binding refs, self.x fn-ref candidates as bare names. Go: receiver methods with Recv::name qualified names + contains edges to the first earlier struct of that name, type_spec struct/interface classification with embedding→extends and interface method nodes, composite-literal instantiates keeping the package qualifier, top-level var/const initializer walks attributed to the declared symbol (#693), 2-hop field chains (#1276), New().Method() re-encode (#645/#608), and the GO_SPEC fn-ref layers. Grammars: tree-sitter-python 0.23.6 + tree-sitter-go 0.23.4 crates, with wasm vendored from the same tags (parser.c sha-matched) — both were 2023-era in tree-sitter-wasms. Gates: extraction sweeps 100% (flask 83/83, django 3,035/3,038 +3 error-file deferrals, gin 99/99, prometheus 978/979 +1); full-init dump-diffs byte-identical on flask (10,833 rows), gin (17,540), django (360,794), and prometheus (213,758); torture fixtures enforced in npm test. DEFAULT_ROUTED now covers typescript/tsx/javascript/jsx/java/ python/go. Full suite: 2,471 tests pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

feat(kernel): R4 — Java port with Lombok synthesis, gate passed, default-on
Java joins the native kernel (codegraph-kernel/src/java.rs), mirroring the wasm extractor's Java paths bug-for-bug: package namespaces, imports, javadoc, annotations→decorates, type_list inheritance, static-final constants, enum constants, anonymous classes (including the TS side's 0-based-line quirk on the extends ref), method_invocation calls with the this.field unwrap and the Foo.getInstance().bar() chain encoding (#645/#608), static-member value reads, method-reference fn-refs (#756), value-reference edges, and the full Lombok member synthesizer (#912: Getter/Setter/Data/Value/Builder/ToString/ EqualsAndHashCode/Slf4j-family with taken-member dedup). The shared docstring/textutil modules moved to crate level. Grammar: tree-sitter-java 0.23.5, with the wasm grammar vendored from the same tag (parser.c sha-matched) replacing tree-sitter-wasms' 2023-era build. Gate (plan §4c): extraction sweeps 100% — gson 262/262, retrofit 341/341, dubbo 4,048/4,048 — plus a Java torture fixture in npm test; full-init dump-diffs byte-identical on gson (49,766 rows), retrofit (62,735), and dubbo (441,266 rows); all R2/R3 repos re-verified; Linux container runs all 23 kernel tests green under CODEGRAPH_KERNEL_EXPECT=1. The gate caught a real cross-language bug: fn-ref dedupe and value-ref self-target checks must compare node ID STRINGS, not node-table rows — ids collide for same-(kind, name, line) nodes, which minified one-line bundles hit routinely (retrofit's website JS exposed it; latent in the TS/JS walker since R2, never released). Fixed in both walkers. Benchmark honesty: dubbo fresh-init on an 11-core Mac is ~flat (parse-loop wall 5,020→4,394ms; total ~11.3s both arms) because that wall is main-thread-bound (reads + store), not worker-CPU-bound — the §6 expectation assumed otherwise. Where worker CPU binds the kernel delivers: dubbo on a 2-CPU/6GB container drops 27.8-28.6s → 22.3-22.8s (~1.25×). The identified lever for the many-core headline is decoding kernel buffers directly into store rows (skipping per-node JS object materialization); the buffer contract already carries everything. DEFAULT_ROUTED now includes java. Full suite: 2,467 tests pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

feat(kernel): R2 — full TypeScript/JavaScript extraction port, byte-parity with the wasm path
Replaces the R1 seed .scm emitter with a bespoke Rust walker (codegraph-kernel/src/tsjs/) that mirrors TreeSitterExtractor's TS/JS paths function-for-function: declarations (incl. #808 field/property classification), qualified names, docstrings (#780 wrapper climbs), signatures, imports/re-exports + per-binding refs, calls with receiver-qualified callees (#1230 literal-receiver skip), instantiations, decorators, inheritance, type annotations (#381), type-alias members + tuple contracts (#359/#634), React component recognition (#841 forwardRef/memo/styled), object-of-functions / zustand-through-middleware / RTK Query endpoints + generated hooks / vuex + pinia store shapes, function-as-value capture with the flush gate (#756), and value-reference edges with the shadow prune (#895/#897). The generic query emitter is deleted — extraction parity needs logic .scm can't express; future languages get walkers too (migration plan §4a). Positions and JS string-slice semantics are emitted in UTF-16 code units natively, so kernel output is byte-identical to web-tree-sitter's — no column diff class exists. Parity evidence (macOS): scripts/kernel-parity.mjs (full-object multiset diff per file) — this repo 353/353 files, excalidraw 643/643 (10,650 nodes / 10,726 edges / 68,307 refs), plus torture fixtures checked into __tests__/fixtures/kernel-parity/ and enforced in npm test by kernel-tsjs-parity.test.ts. The strict compare caught one real decoder bug the loose harness missed: refs must NOT carry denormalized filePath/language at the extractFromSource seam (the store fills them). Perf: extraction 2.6× single-thread on excalidraw (487ms vs 1,255ms, identical outputs). Routing stays opt-in (CODEGRAPH_KERNEL_LANGS) until the R3 equivalence gate (large repo, DB dump-diff, retrieval invariants, agent A/B, Linux/Windows) passes.

feat(kernel): R1 scaffold — napi-rs extraction kernel, buffer contract, routing + fallback, grammar-parity CI
Phase 0 of the Rust extraction-kernel migration (docs/design/ rust-kernel-migration-plan.md, now checked in with §3a recording the shipped state): - codegraph-kernel/ napi-rs crate: extractFile(path, content, language) → five flat buffers (meta/nodes/edges/refs/arena), one JS boundary crossing per file. Node ids computed Rust-side, byte-identical to generateNodeId (pinned by test vector). Reserved per-node metrics slot for the Arc 3.2 code-metrics work. - Generic .scm-driven emitter (@def.<kind>/@name/@ref.<kind> captures, byte-range scope stack → ::-joined qualified names, contains edges, refs attributed to the innermost enclosing symbol). Seed TS/JS queries are smoke-level; R2 replaces them with the full port. - Routing seam in extractFromSource with per-file wasm fallback. DEFAULT_ROUTED is empty — no behavior change until a language passes its equivalence gate (R3). Dev opt-in: CODEGRAPH_KERNEL_LANGS. Kill switch: CODEGRAPH_KERNEL=0. Loader verifies ABI + kind tables before routing; EDGE_KINDS became a runtime array because kind order is now wire contract. - Grammar-source parity: vendored TS/TSX/JS wasm grammars built from the exact crate revisions (tree-sitter-typescript v0.23.2, tree-sitter-javascript v0.25.0, checked-in parser.c, ts-cli 0.25.10) — the tree-sitter-wasms builds were 2023-era, which the new kernel-grammar-parity test caught on day one. Production TS/JS parsing gets 2.5 years of grammar fixes; full suite green (2456 tests). - Build/release wiring: scripts/build-kernel.sh + npm run build:kernel; release.yml kernel prebuild matrix (continue-on-error — the kernel is optional everywhere, bundles fall back to the wasm path); bundles stage lib/kernel/codegraph-kernel.node; release job runs the kernel suites with CODEGRAPH_KERNEL_EXPECT=1.
