Colby MchenryandClaude Opus 5.5 9c4794d694 fix(rust): a call keeps its whole receiver chain, and links through method calls in it (#2846)
A Rust method call made through more than one field, or on what another
method returns, was recorded by its bare method name in both extractors:
self.services.store.put("a") became `put`, as did self.store().put("m").
Only a single field kept its receiver (self.store.put). The edge's
refName then said nothing of which value the call goes through, and a
call on a method call's value was never typed, so self.store().put("m")
stayed unresolved. PR #2831 had already made the field-chain calls link
by reading the receiver from the source text, but their names stayed
bare.

Both extractors now keep a receiver that is a chain of fields and method
calls on `self` or on a name, a call written `name()` with its arguments
and turbofish dropped, up to 16 links: self.services.store.put,
self.store().put, vis.map.get, self.0.len, x.get().put. The shapes that
already kept a receiver (x.m, self.m, self.<field>.m, Foo::new().m) are
unchanged; a parenthesized receiver, `?`, `.await`, an index and a longer
chain rooted at a path keep the bare name. The kernel's receiver_chain
mirrors the wasm extractor's rustReceiverChain byte for byte.

Resolution reads such a call as the bare-named call was read before
(rustChainedCallByName, at the top of resolveOneIn), so the frameworks,
the strategies and the scope gates see what they saw, and the edge keeps
the call as written. The chain goes along: the written-receiver hook
reads the receiver the chain names where the call is written
(rustChainedReceiver), so a method call's value is typed from that
method's signature, and a later link that calls the same name again is
told apart instead of being left to a guess by the name.

Validation:
- New __tests__/rust-receiver-chains.test.ts (10 tests): the issue's
  workspace verbatim plus self.store().put("m"), chains whose links call
  the same name through self, a tuple field and a parameter, a call on a
  method's std return value, the recorded shapes and the 16-link cap,
  and a sync that adds the missing method. Red on main's sources, 7 of
  10 failing on both the wasm and the kernel path; green with the fix.
  The Rust kernel parity suite gains a chain case. The extraction test
  that pinned the old collapse now pins the chains.
- A/B against main 865ddf4a (same groups against d8338275), both arms
  with the native kernel, every changed call edge read. Per repo: edges
  that only gained their receiver in refName / same target now by type /
  wrong removed / right added / wrong to right:
  ripgrep 3fce3b5b: 159 / 45 / 6 / 6 / 15
  axum 86aa6153: 115 / 25 / 0 / 14 / 7
  tokio 8a2408ed: 1039 / 124 / 36 / 29 / 27, and 1 right link lost
  lemmy 92e077b5: 190 / 24 / 3 / 1 / 3, 1 right lost, 1 wrong added
  The two lost links and the wrong one follow rules the typed-receiver
  reading already applies to typed locals on main: a function-local glob
  `use` does not shadow a file-level named `use` (tokio), a call on a
  dependency's type reaches only impls of project traits, and `x.into()`
  takes the type's explicit `impl Into` (lemmy). Controls gin and
  express: byte-identical dumps. Nodes are identical on every repo.
- Kernel parity (Rust), ripgrep, axum, tokio, lemmy: 1752/1752 files at
  byte parity, 0 deferred.
- Index cost, interleaved median of 3 (wall): ripgrep 3.15 s -> 3.15 s,
  axum 3.39 s -> 3.42 s, tokio 10.48 s -> 10.54 s, lemmy 5.14 s ->
  5.15 s; CPU within noise.

Fixes #2836

ed1a89fb0f fix(rust): a variant path references the enum that declares it (#2328) (#2354)
Using an enum only through its variants (`mode::Mode::A` in an expression,
`mode::Mode::A => 1` / `Mode::B => ...` in a match, a `Mode::C(x)` or
`Mode::D { .. }` pattern) recorded no reference to the enum, so code that
builds or matches variants was missing from the enum's callers and impact.
Only a type annotation (`fn takes(_m: Mode)`) produced one.

Cause: Rust was not in the static-member pass, which turns `Enum.value` /
`Type::CONST` reads into references for Java, C#, Kotlin, Swift, Scala,
Dart, PHP and C++, and a path to a variant that is not a call or a struct
literal reaches no other extractor.

Fix:
- Extraction (wasm extractor and native kernel, mirrored): a path whose
  last segment is capitalized emits a `references` ref named by its
  receiver (the segment before it; `Self` read as the impl's type, nothing
  in a trait), positioned at the receiver, so a `mode::` prefix scopes it
  exactly as it scopes a type annotation. Covers value reads, match arms,
  `|` / `if let` patterns, tuple- and struct-variant patterns and a variant
  passed as a value. A call's callee (`Mode::C(1)`, `Foo::new()`), a struct
  literal, a longer path's prefix, a `use` tree and a lowercase receiver or
  member emit nothing.
- Resolution (isRustNameInScope): a reference written `Name::Variant` or
  `Self::Variant` lands only on an enum that declares that variant, after
  the usual Rust scoping (module path, `use`, glob, prelude, std and
  dependency imports). ripgrep's `Match::None` reaches `ignore`'s enum, not
  the matcher's `struct Match`; std variants (`Ordering::Less`,
  `Option::Some`) never reach a same-named project enum; associated consts
  and functions (`Limits::MAX`, `Mode::ALL`, `Foo::new()`) reference no
  type. `Self::X` is read as the impl's type, never through a path written
  elsewhere on its line.

Adapted from #2330 by @danusha2345: the extraction half (both walkers) and
most of the tests are theirs. Changed here:
- The resolver accepts a declared variant only. #2330 also accepted any type
  whose file holds a variable or const of the item's name; impl consts are
  file-level variables in the graph, so that cannot tell a type's associated
  const from another type's or a top-level one.
- The walkers check the node kind before looking at its parent, and the
  body walk hands the parent down: #2330 called `parent()`, which walks down
  from the tree's root, for every node of every body, which nearly doubled
  the kernel's Rust extraction time on tokio (2.1 s -> 3.9 s); now within
  noise of main.
- EXTRACTION_VERSION is not bumped again (already 28 on main).

Verification: __tests__/rust-enum-variant-reference.test.ts (10 tests):
6 fail on main in wasm mode, in kernel mode, and with this TypeScript over
main's kernel binary; 10/10 pass in both modes. The kernel parity case
covers every shape and asserts the refs exist; the kernel-parity sweep over
ripgrep, alacritty and tokio is 1004/1006 files byte-parity, 0 diffs (2
parse-error files defer to wasm by policy).

Validation (native kernel loaded, main -> branch, edges keyed by
QN/kind/file/line): ripgrep +822/-0, alacritty +917/-0, tokio +665/-0, all
`references -> enum`, node counts unchanged. Every added edge's source
reads `Name::Variant` / `Self::Variant` at its column and its target enum
declares that variant; no std enum targets. New symbol->enum pairs:
ripgrep +220, alacritty +253, tokio +254; enums with no referencer before
and one now: 31 / 13 / 31. One wrong target on tokio
(`oneshot::error::TryRecvError::Empty` -> mpsc's `TryRecvError`) comes
from the existing path rule that checks only the last module segment, which
type annotations share. Index time on tokio stays within noise of main
(interleaved runs; resolveOne time 27.7 s vs 31.2 s summed over workers).

Colby MchenryandClaude Opus 5.5 87e79c6ee8 fix(dead-code): exclude annotated Tauri commands (#1543) (#2019)
Rust command attributes were not retained as decorators, so runtime entry points could appear as dead code.
Preserve tauri::command metadata in both native and fallback extraction and reuse the existing decorated exclusion.
Add SQLite regression coverage and native/fallback parity checks, including negative cases.

71d049cd28 fix(rust): index unit structs — bodiless is a definition, not a forward decl (#1800)
Land upstream PR #1514 for issue #1513 by cherry-picking
ctype_lab's a94c9dc94e.

Keep allowBodilessStruct as a Rust-only opt-in, with matching behavior in
the wasm/TypeScript walker and native kernel. Create the node before
checking for a body and walk members only when present. Resolve against
main's shared struct/union walker while retaining its stack guard, kinds,
fields, and existing impl-receiver fixes.

Verified FAIL to PASS on Linux x64 with Node 22.19.0 after rebuilding via
tsc, copy-assets, and build:kernel. The identical fixture on main 7b339373
had two structs and two implements edges; fresh wasm (CODEGRAPH_KERNEL=0)
and native indexes now have three of each. UnitStruct and its Greet
implements edge are recovered; tuple and brace structs remain intact.
The native run loaded the rebuilt kernel and completed without fallback.

Focused extraction.test.ts and kernel-rustlang-parity.test.ts runs:
645 tests passed with the kernel disabled, and 645 with it enabled;
all three parity tests ran in each configuration, with no skips.

(cherry picked from commit a94c9dc94e)

Colby Mchenry 12f7a59f26 fix(rust): qualify generic/lifetime impl methods by the implementing type, not the trait (#1588) (#1596)
Fixes #1588.

## What was wrong

The receiver of an `impl` block — the name that qualifies its methods, owns the `contains` edge, and sources the `implements` edge — was found positionally: the **last bare `type_identifier` child** of the `impl_item`. That works for `impl Source for FileSource`. But once the implementing type carries parameters it parses as a `generic_type`, and the only bare identifier left is the **trait's**:

```rust
impl Source for FileSource         →  FileSource::read   ✓
impl<T> Source for BufSource<T>    →  Source::read       ✗  (should be BufSource::read)
impl<'a> Iterator for Parents<'a>  →  Iterator::next     ✗
impl Trait for &Foo                →  Trait::method      ✗
```

Two consequences, both reproduced on `main`:

- `BufSource::read` did not exist in the graph, so `resolveMethodOnType("BufSource", "read")` and "who calls `BufSource::read`" had no answer, and every generic implementation of a trait collapsed onto the same trait-qualified name.
- Because the impl's method carried the trait's qualified name, the interface-impl synthesizer treated the impl **body** as a second trait declaration and emitted a dispatch edge from it (`Source::read -> FileSource::read`, registered at the generic impl's line — a body of `{ 0 }` containing no call at all).

The native kernel (`rustlang.rs`) mirrored the positional rule deliberately, bug-for-bug, to hold byte-parity with the TS walker — its header said "preserve, never fix via the grammar's trait:/type: fields". So the fix has to land on both sides at once.

## What this does

Both extractors now read the grammar's **named fields** instead of scanning children. One shared rule (`rustImplTypeName` in `languages/rust.ts`, `impl_type_name` in the kernel), applied to `impl_item.type`:

| implementing type | node | receiver |
|---|---|---|
| `Foo` | `type_identifier` | `Foo` |
| `Foo<T>` / `Foo<'a>` | `generic_type` → its `type` field | `Foo` |
| `m::Foo` | `scoped_type_identifier` → its `name` field | `Foo` (was: no receiver) |
| `&Foo` / `&'a mut Foo` | `reference_type` → its `type` field | `Foo` |
| `(A, B)`, `dyn Tr`, `*const T`, `u32`, fn types | anything else | none — extracted as plain functions, exactly as before |

The `implements` back-reference reads `impl_item.trait` (full text, so `fmt::Display` and `From<u32>` keep their spelling) and bails when the field is absent (inherent impl). Everything else — the no-scope impl quirk, the source-order `contains` owner scan, method extraction — is untouched; the `contains` edge simply lands on the implementing type now instead of the trait.

The kernel header comment, the parity test's description, and the two design docs that documented the quirk as "preserve" are updated to say what changed.

## Measured on ripgrep (110 `.rs` files, `main` build vs this branch)

| | main | this PR |
|---|---|---|
| nodes / methods | 4029 / 2202 | 4029 / 2202 |
| impl methods qualified by a **trait** name (node outside that trait's extent) | 61 | **0** |
| `Iterator::*` methods | 2 | 0 |
| duplicate method qualified names | 77 | 42 |
| synthesized `interface-impl` edges originating **outside** any trait declaration (the phantom fan-outs) | 38 | **0** |
| synthesized `interface-impl` edges originating at a real trait declaration | 33 | **52** |
| plain (non-heuristic) `calls` edges | 9098 | 9098 |

So the synthesizer lost every phantom edge and *gained* 19 legitimate fan-outs to implementations it could not previously see as implementations. `contains` edges went 5237 → 5224: the 13 removed were trait→impl-method edges produced by the mis-qualification.

The issue's repro now gives `BufSource::read` at line 12, `BufSource -> Source`, and both synthesized edges registered at the declaration (line 2) — identical on the kernel path and with `CODEGRAPH_KERNEL=0`. (The remaining `UsesFile::go -> BufSource::read` exact-match guess there is the separate `self.field.method()` receiver problem, #1585, which stacks on this.)

## Tests

- `__tests__/extraction.test.ts` (Rust Extraction): method qualified names for generic / lifetime / reference / scoped / generic-trait impls; the trait's qualified name names exactly one node; `implements` refs come from the implementing type for every shape; the `contains` edge lands on the type; tuple / `dyn` impls keep producing plain functions with no `implements` ref.
- `__tests__/resolution.test.ts` (end-to-end): `Source::read` names only the declaration; dispatch fans out to **both** `FileSource::read` and `BufSource::read`, every synthesized edge registered at line 2; neither impl body sprouts a synthesized call.
- `__tests__/fixtures/kernel-parity/torture.rs` grows all the new impl shapes; `kernel-rustlang-parity` (LF + CRLF) passes against the rebuilt kernel.
- `CODEGRAPH_KERNEL_EXPECT=1 npx vitest run __tests__/kernel-*.test.ts` — all 15 suites, 147 tests pass.
- Full `npm test`: 3180 passed, 9 skipped, 1 failed — `mcp-daemon.test.ts > daemon idle-times-out after the last client disconnects`, a 30 s timing test that passed on re-run in isolation (the machine was running four parallel suites and kernel builds at the time); unrelated to extraction.

Re-index after upgrading to pick up the corrected names.

Colby MchenryandClaude Fable 5 f1ca991943 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.
