Every TS `public_field_definition` / JS `field_definition` extracted as a
method-kind node, so a plain field (`public fonts: Fonts;`) was reported
as callable: class shape was misrepresented, kind-based filtering was
defeated, and bare-name call resolution landed on data fields — typeorm's
boolean `ColumnMetadata::isArray` field was soaking up Array.isArray(...)
call edges (685 such wrong edges on typeorm alone).
Classification now follows the VALUE (classifyMethodNode hook, mirroring
resolveBody's callable detection): arrow-function / function-expression
fields and HOF-wrapped ones (`onScroll = throttle(() => {…})`) stay
methods with their bodies walked; everything else becomes a property that
keeps its type-annotation references edge, visibility, static-ness, and
decorators. Field initializers are now walked too (`history =
createHistory()` attributes the call to the property — previously
invisible), and JS class fields — whose name lives in the grammar's
`property` field, so they never extracted a symbol at all — now appear in
the graph (resolveName on the JS extractor).
With fields correctly kinded, `this.X` callback registration is re-enabled
for TS/JS (removed in #807 because field pseudo-methods made it mostly
wrong): `this.<member>` candidates resolve CLASS-SCOPED
(resolveThisMemberFnRef) — the target must be a function/method sharing
the from-symbol's qualified-name class prefix, same file, no fallback —
so `addEventListener("online", this.onOfflineStatusToggle)` and API-object
wiring (`{ mutateElement: this.mutateElement }`) produce registration
edges to the enclosing class's own method, while `this.fonts` (a
property) and inherited/unknown members yield no edge.
A/B (baseline = #807 main): excalidraw / typeorm / express — node counts
identical on all three; kinds shift method→property only (typeorm: exactly
7,406 swapped; excalidraw also corrects 5 anonymous-class mock fields that
were function-kind); every one of the 736 dropped call edges targeted a
node that is now a property (calls into data fields — verified 100%);
gains are retargets to real callables, initializer-call attributions, and
+74/+7 class-scoped this.X registration edges (sampled: addEventListener/
removeEventListener wiring, imperative-API method maps). Full suite green
(1386).

Ports the #645/#608 chained-receiver mechanism to Pascal/Delphi — which I'd
previously mis-scoped as blocked. The paren'd chained form extracts fine; it just
hit the chained-call gap like the others (with a decoy, `TFoo.GetInstance().DoIt()`
mis-resolved to a same-named method on an unrelated class).
- pascal.ts: getReturnType reads the method's `typeref` (a `function GetInstance:
TBar` returns TBar; an interface return `IFoo` is captured too).
- tree-sitter.ts: extractPascalCall now re-encodes a chained call `TFoo.GetInstance().DoIt`
(the exprDot's receiver is an exprCall) instead of collapsing it to bare `DoIt`.
Gated on the Delphi type-naming convention (`TFoo`/`IFoo`) so a capitalized
VARIABLE chain (Pascal capitalizes locals too — `Curve.X().Y()`, `Self.X().Y()`)
stays bare and keeps its existing bare-name resolution.
- name-matcher.ts: `pascal` joins the dotted-chain gate + CHAIN_LANGUAGES +
CONSTRUCTS_VIA_BARE_CALL (a `TFoo(x)` typecast yields a TFoo). When the factory's
return type wasn't captured (a `constructor Create` has no `: TBar` but returns
its class), resolve the method on the factory class itself. resolveMethodOnType
validates, so a wrong inference yields no edge.
Validation: 4 synthetic tests (factory+decoy, constructor chain, typecast chain,
absent-method safety). Real-repo A/B on PascalCoin (772 files): +19 / -18 — 15 of
the -18 are correct class→interface retargets (`GetInstance(): IAsn1OctetString`
resolves `.GetOctets` on the declared interface, not baseline's concrete-class
guess); 3 are negligible drops (0.02%). EXTRACTION_VERSION 15->16. Full suite green.

Ports the #645/#608 chained-receiver mechanism to Objective-C. A message send
whose receiver is itself a message send — `[[Foo create] doIt]` — used to drop
the receiver, so `doIt` name-matched a same-named method on an unrelated class
(commonly a test helper's `init` or an Apple-SDK method).
- objc.ts: getReturnType reads the method's `method_type`, SKIPPING nullability /
ARC qualifiers (`nonnull instancetype` must yield instancetype, not `nonnull`).
- tree-sitter.ts: the message_expression branch now re-encodes a chained send
`[[Foo create] doIt]` as `Foo.create().doIt` when the inner receiver is a
capitalized class and the outer selector is unary.
- name-matcher.ts: `objc` joins the dotted-chain gate + CHAIN_LANGUAGES. A
class-message factory returns an instance of the RECEIVER class by convention
(`instancetype`), so when the factory's own return type isn't recoverable
(`alloc`/`new`/`shared…` return instancetype, or aren't user nodes), the
receiver's type is the class itself — this resolves the ubiquitous
`[[X alloc] init]` and singleton chains. resolveMethodOnType validates against
the class and its supertypes, so a wrong inference yields no edge.
Validation: 4 synthetic tests (factory+decoy, superclass conformance, absent-method
safety, the nonnull-instancetype singleton). Real-repo A/B on SDWebImage (208 files):
+35 / -75 — all corrections (the -75 are wrong `init` mis-matches to a test helper /
wrong class, retargeted to the right class's init in the +35, plus 2 Apple-SDK chains
on unindexed classes). db stable, no node explosion. EXTRACTION_VERSION 14->15.
Full suite green.

Ports the #645/#608 chained-receiver mechanism to Dart, plus makes Dart factory
and named constructors first-class so their chains can resolve at all. A call
whose receiver is itself a call — `Foo.create().bar()` (static factory or
factory/named constructor) — used to drop the receiver to a bare `bar`, which
name-matched a same-named method on an unrelated type (commonly a stdlib
`Option`/`Iterator` `.map`/`.where` mis-tied to the project's own class).
- dart.ts: extractBareCall now re-encodes `Foo.create().bar` when the chain
starts with a capitalized type; getReturnType captures the return type (generic
`List<Foo>` → `List`); factory (`factory Foo.create()`) and named (`Foo._()`)
constructors are indexed as `Foo::create` / `Foo::_` with return type = the
class (via resolveName + getReturnType + constructor_signature in methodTypes).
- The UNNAMED ctor `Foo()` is deliberately NOT extracted (isMisparsedFunction),
so plain construction stays an `instantiates` edge to the class rather than a
call to a phantom `Foo::Foo` method.
- dartCtorInfo validates a "constructor" against the enclosing class name, so a
method tree-sitter MISPARSES as a constructor — `@override (A, B) m()`, where
the annotation swallows the record return type and `m()` looks like a one-id
constructor_signature — is still extracted as the method it is (regression
found on localsend; covered by a new test).
- name-matcher.ts / index.ts: `dart` joins the dotted-chain gate,
CONSTRUCTS_VIA_BARE_CALL (case construction), and CHAIN_LANGUAGES (conformance
for superclass/mixin methods). resolveMethodOnType validates, so a wrong
inference yields no edge.
Validation: 7 synthetic tests (static factory, factory/named ctor, construction,
conformance, absent-method safety, the misparse regression, instantiation-not-
hijacked). Real-repo A/B on localsend (368 Dart files): hand-written +17/-10 — all
corrections (the -10 = 7 wrong stdlib/extension misattributions removed + 3 ctor
source-renames), plus additive factory/named-ctor call resolution. Instantiation
preserved; no node explosion. EXTRACTION_VERSION 13->14. Full suite green.

Ports the #645 (C++) / #608 (PHP) chained-receiver mechanism to Scala. A call
whose receiver is itself a call — `Foo.create().bar()` (companion factory),
`Builder(cfg).bar()` (case-class apply), or a fluent chain — used to drop the
receiver to a bare `bar`, which name-matched a same-named method on an unrelated
type. The most common wrong edge was a stdlib `Option`/`Iterator` `.map`/`.flatMap`/
`.foreach` mis-attributed onto the project's own same-named class.
- scala.ts: `getReturnType` reads the `return_type` field — generic `List[Foo]`
→ container `List`, qualified `pkg.Foo` → `Foo`, `this.type` left undefined.
- tree-sitter.ts: re-encode `Foo.create().bar` when the inner call's receiver chain
starts with a capital (companion factory / case-class apply); instance chains
(`list.map().filter()`) stay bare.
- name-matcher.ts: `scala` joins the dotted-chain gate + CONSTRUCTS_VIA_BARE_CALL
(case-class `apply` constructs the class); resolveMethodOnType validates, so a
non-conventional `apply` returning another type yields no edge, not a wrong one.
- index.ts: `scala` joins CHAIN_LANGUAGES so trait-inherited methods resolve via
the conformance second pass.
Validation: 4 synthetic tests (factory+decoy, case-class apply, trait conformance,
absent-method safety). Real-repo A/B on gatling (750 Scala files): +14 / -59 unique
edges — all corrections. The +14 are retargets (e.g. `HttpProtocolBuilder(cfg).baseUrl`
now resolves to HttpProtocolBuilder::baseUrl, not the same-named private BaseUrlSupport
helper); the -59 are wrong edges removed (stdlib Option/Iterator monad calls
mis-tied to the project's Validation::*, self-loops, decoy collisions) — zero genuine
factory chains dropped (verified: gatling has no real Validation.success().map() chains).
db stable at 40 MB. EXTRACTION_VERSION 12→13. Full suite green.

* fix(go): resolve chained factory-function calls New().Method() (#750)
A Go call through a chained factory function — `New().Method()`,
`With(cfg).Build()` — dropped the receiver to a bare method name, which then
attached to a same-named method on an unrelated type (a wrong edge) or didn't
resolve. Ports the #645/#608 mechanism for Go's bare-factory receivers:
- Part 1: capture Go return types; a pointer `*Foo` -> `Foo`, a multi-return
`(*Foo, error)` -> its first result, qualified `pkg.Foo` -> `Foo`.
- Part 2: encode a bare-factory chain (`New().Method`), gated to an `identifier`
receiver so instance chains (`obj.Method().Other()`) keep bare-name.
- Part 3: matchDottedCallChain bare-inner Go branch looks up the FUNCTION's
return type, then resolves+validates the method on it. Wired into the
conformance pass so a method promoted from an embedded struct (`type Widget
struct{ Base }` -> the existing `extends` edge) resolves. FALLBACK: when the
inner isn't a resolvable function (a package-level VARIABLE holding a function
value, e.g. gin's `engine()`), fall back to bare-name so the edge isn't dropped.
Validated: synthetic decoy + args + multi-return + embedded-conformance + absent
safety tests (4/4); full suite green. Real-repo A/B on gin (99 .go): pre-fallback
-40 = 25 wrong self-loops removed (good) + 15 correct `Engine::ServeHTTP` dropped
(gin's ginS variable-factory `engine()`); the fallback recovers the 15. gin A/B
re-confirm with the fallback is PENDING (local index flakiness, not a code issue).

* fix(go): stop the chained-call fallback from looping the batched resolver
The Go variable-inner fallback (for chains like `engine().ServeHTTP()` whose
inner is a package-level var, not a factory function) resolved the method via
a synthetic bare-name ref and propagated THAT ref as `.original`. Its
`referenceName` was the bare `ServeHTTP`, not the stored `engine().ServeHTTP`,
so `resolveAndPersistBatched`'s keyed `deleteSpecificResolvedReferences` no-oped,
the offset-0 batch never drained, and the loop re-resolved + re-inserted the
same rows forever — a runaway that grew a 99-file repo (gin) to 5,050,206 edges
/ 1.4 GB before filling the disk.
- name-matcher.ts: tie the bare-name match back to the original `ref` so the
batch-cleanup delete matches the stored row and the loop drains.
- index.ts: add a non-progress guard to resolveAndPersistBatched — if the
unresolved_refs table doesn't shrink after a batch, stop instead of growing
the graph without bound (defense-in-depth for any future keyed-delete mismatch).
- resolution.test.ts: regression test for the variable-inner chain — asserts the
fallback edge resolves AND the edge count stays bounded (no explosion).
gin A/B (post-fix): db 5.8 MB / 3,699 calls edges; net-zero unique-edge diff vs
main (the fallback recovers the dropped edges, adds no wrong ones). Full suite green.

A Rust call through a chained associated function — `Foo::new().bar()`,
`Foo::with(cfg).build()` — dropped the receiver to a bare method name, which
then attached to a same-named method on an unrelated type (a wrong edge) or
didn't resolve. Ports the #645/#608 mechanism for Rust's `::` receivers:
- Part 1: capture Rust return types; `-> Self` yields the `self` marker (resolved
to the impl's own type, like PHP), references/generics are unwrapped/reduced.
- Part 2: encode an associated-function chain (`Foo::new().bar`), gated to a
scoped_identifier receiver so instance chains (`x.foo().bar()`) keep bare-name.
- Part 3: resolve via matchScopedCallChain (PHP's `::` resolver, generalized),
validated by resolveMethodOnType. Wire Rust into the conformance second pass
(matchScopedCallChain variant) so a chained method provided by a trait the type
implements (`impl Trait for Type` → existing implements edges) resolves too.
Validated: synthetic decoy + args + Self + trait-default-conformance + absent
safety tests; full suite green (lone failure is the known-flaky #662 daemon test,
passes in isolation). Real-repo A/B vs main: clap (329 .rs) a net precision win —
**+937 added (96% correct builder methods), 622 wrong->right retargets**
(`Command::new().arg()` was mis-resolving to `ArgGroup::arg`, now `Command::arg`),
+162 net unique edges; the pure-drops are largely wrong bare-name edges the fix
correctly stops emitting. tokio-rs/bytes 0/0 (no regression). Known limit: the
single-hop mechanism re-encodes only the first hop of a chain (deeper hops keep
bare-name) — clap's unusually deep builder chains are partly covered.

Completes Swift in the #750 chained-call series (after Java #751, Kotlin #752,
C# #753, conformance #754). Two parts:
1. Swift chained-call resolution (the #645/#608 mechanism): capture Swift return
types (positional, member types -> last segment), encode capitalized-receiver
chains `Foo.make().draw()` / `Foo(args).draw()`, resolve+validate via the
shared matchDottedCallChain (+ constructor branch). Fixes the decoy wrong-edge
bug where a chained method dropped to a bare name and attached to a same-named
method on an unrelated class.
2. Nested-type extension naming fix: `extension KF.Builder: KFOptionSetter` parsed
as a class_declaration named `KF.Builder` (dot) — inconsistent with the type's
own declaration `KF::Builder` (name `Builder`) — so the extension's conformances
and members were invisible to a chained call on the type. A Swift resolveName
now names a nested-type extension by its last segment (`Builder`), so its
`implements`/`extends` edges and methods are found by the supertype walk
(conformance #754) and the simple-name method match.
Validated: synthetic decoy + args + constructor + absent-method tests; full suite
green; nested-extension repro (`KF.url().onSuccess()` resolves via conformance to
the protocol method). Real-repo A/B vs main (conformance) — Alamofire and
Kingfisher both **0 added / 0 removed, node count unchanged**: NEUTRAL and SAFE.
The prior -168 Kingfisher regression (from the naming inconsistency) is eliminated;
Swift's unique-named fluent methods already resolved by bare name, so the chain
path lands the same edges — the value here is decoy-collision correctness, the
nested-extension naming fix, and consistency with the other four languages.
EXTRACTION_VERSION 9 -> 10.

A C# method called through a static factory or fluent chain —
`Foo.Create().Bar()`, `JObject.Parse(s).Property(...)`,
`Instant.FromUtc(...).InZone(zone)` — lost the receiver's type, so the chained
method didn't resolve and the call was invisible to callers/impact/trace. Ports
the #645/#608 mechanism to C# (additive, like Java #751):
- Part 1: capture C# return types in the extractor, reading the `returns` field
(`static Foo Create()` -> `Foo`); predefined/array/generic/nullable/namespaced
types are normalized or skipped.
- Part 2: encode a chained `member_access_expression` receiver
(`Foo.Create(args).Bar()`) as `inner().Bar` with normalized empty parens, so
factory calls that take arguments still split. Non-chained member calls keep
their existing `recv.Method` text.
- Part 3: resolve via the shared matchDottedCallChain (now Java/Kotlin/C#),
validated by resolveMethodOnType so a wrong inference yields NO edge.
Known limitation (safe): C# extension-method chains don't resolve, since the
method lives on the extension class, not the receiver's type — no edge, never a
wrong one.

A Kotlin method called through a companion-object factory, fluent chain, or
constructor — `Foo.getInstance().bar()`, `Config.create(opts).build()`,
`STMTransaction(f).commit()` — dropped the receiver to a BARE method name, which
then name-matched a same-named method on an unrelated class (a wrong edge) or
failed to resolve. Ports the #645/#608 mechanism to Kotlin:
- Part 1: capture Kotlin return types in the extractor. tree-sitter-kotlin
exposes no field names, so the return type is read positionally (the type node
after function_value_parameters); inferred/Unit/Nothing returns yield none.
- Part 2: encode a CLASS/companion-factory call-receiver chain as `inner().method`.
Gated to a capitalized receiver (`Foo.getInstance()` / `Foo(args)`) so instance
chains (`list.filter{}.map{}`) keep their bare-name behavior — re-encoding those
would only drop the edge, regressing recall in fluent codebases.
- Part 3: generalize matchJavaCallChain -> matchDottedCallChain (shared by the JVM
dot-notation languages); resolve the method on the factory's return type, or on
the constructed class for a Kotlin `Foo(args).method()` receiver. Validated via
resolveMethodOnType, so a wrong inference yields NO edge.
Validated: synthetic decoy + args + absent-method safety tests; full suite green;
real-repo A/B on arrow-kt/arrow (734 .kt) — node count identical (no explosion),
+49 validated-correct chained edges, and the removed edges are wrong bare-name
guesses the fix correctly stops emitting (419/438 from test/doc files; the 18
from product code are stdlib `.apply{}`, self-loops, and bare-name mismatches) —
a net precision improvement, ~0 correct product edges lost. Java path unchanged

A Java method called through a static factory or fluent chain — `Foo.getInstance().bar()`,
`Config.create(opts).build()` — lost the receiver's type, so the chained method either
didn't resolve at all or (when a same-named method existed on an unrelated class) attached
to whichever class was indexed first. Ports the #645 (C++) / #608 (PHP) 3-part mechanism:
- Part 1: capture Java return types in the extractor (skip void/primitives/arrays,
unwrap generics, strip package qualifier).
- Part 2: encode a chained-call receiver as `inner().method` with normalized empty
parens, so factory calls that take arguments still split.
- Part 3: matchJavaCallChain resolves the chained method on the factory's return type,
validated via resolveMethodOnType so a wrong inference yields NO edge (never a wrong one).

A method called through a PHP fluent static factory — `ApiClient::for($c)->createOrder()`,
the canonical Laravel per-credential/per-tenant client idiom — produced no
`calls` edge: the receiver of `->createOrder` is the `Cls::for(...)` static
call, whose result type was never recovered, so the edge was dropped and
`codegraph_callers` returned nothing.
Same shape as the C++ singleton/factory fix (#645), reusing its return_type
column + the chained-call mechanism:
- Capture PHP return types (getReturnType): `: self` / `: static` / `$this`
stored as the `self` marker, a concrete `: Type` as its short name,
primitives/unions dropped.
- Encode the chained scoped-call receiver as `Cls::for().method` so the
resolver can split it (PHP-gated, in extractCall).
- New matchPhpCallChain: look up the factory's return type (`self` → the
factory's own class; concrete → that class), then resolve AND validate the
method on it — a wrong inference yields no edge, never a wrong one.
EXTRACTION_VERSION 4->5 (re-index to populate PHP return types + chained edges).
Validated on koel (1383 PHP files): node count identical (no explosion),
0 edges lost, +80 chained-call edges recovered; synthetic tests cover the

PHP's importTypes only captured namespace_use_declaration, so
include/require(_once) — the dependency mechanism in procedural and
script-style PHP — never produced edges. callers, impact, and trace
missed the entire file-include graph; only namespace `use` became a
dependency edge.
Capture the four include/require expression types and emit file→file
imports edges, reusing the path-based resolution that C/C++ #include
already goes through. Only static string-literal paths are resolved
(relative to the including file); dynamic forms (include $var,
require __DIR__ . '/x', interpolated strings) are skipped.
Include PATHS are distinguished from namespace `use` symbols by shape: a
path contains '/' or '.', which PHP identifiers and FQNs never do. A
path-shaped include that doesn't resolve to a known project file is left
unresolved and does NOT fall back to the symbol name-matcher, which would
otherwise mis-connect "inc/db.php" to an unrelated db.php elsewhere — a
wrong edge is worse than a missing one.

A C++ method call whose receiver is another call's result — `Foo::instance().bar()`,
`WidgetFactory::create().draw()`, `openSession()->run()`, or the same stored in an
`auto` local first — lost the receiver's type during extraction. The callee degraded
to a bare method name, so when two classes shared a method name the call silently
resolved to whichever was indexed first (or not at all), corrupting callers / impact /
trace with a plausible-but-wrong edge.
Three parts:
- Capture C++ return types (new nodes.return_type column, schema v5): the
function_definition's `type` field, normalized — smart-pointer pointee unwrapped,
void/primitives dropped.
- Preserve the inner-call receiver in extraction: a C/C++ field_expression whose
receiver is itself a call is encoded `inner().method` instead of dropping to the
bare name. Other languages keep the existing behavior.
- New resolution strategy (matchCppCallChain): infer the receiver's class from the
inner call's return type, then resolve AND validate the method on it. Handles
singletons/accessors, factories returning a different type, free-function
factories, make_unique/make_shared/new/direct construction, single-level member
chains, and namespace-qualified inner calls. A wrong inference yields no edge,
never a wrong one.
EXTRACTION_VERSION 2->3 (re-index to populate return types).
Validated on the issue repro + spdlog: node count stable (no explosion),

Batch of small, localized fixes from an open-issue triage:
- .codegraph/.gitignore now ignores everything but itself, so the database,
daemon.pid, sockets, and logs stop showing up in git status (#492, #484)
- MCP server answers resources/list and prompts/list with empty lists instead
of -32601, clearing scary log lines in opencode/Codex (#621)
- index SAP HANA .xsjs/.xsjslib as JavaScript (#556) and TS .mts/.cts (#366)
- visit anonymous AMD/CommonJS/IIFE wrapper bodies so their inner functions and
calls are indexed instead of coming up empty (#528)
- batch the changed-file lookup so a huge first sync no longer hits
"too many SQL variables" (#540)
- list files with `git ls-files -z` so non-ASCII/CJK paths survive
core.quotepath and are no longer silently skipped (#541)
- attach Go methods on generic receivers (*T[P]) to their type (#583, RC1)
- impact no longer climbs the structural `contains` edge, so a leaf symbol
stops dragging in its sibling methods (#536)

Wrap top-level declarations of `.kt` / `.java` files in an implicit `namespace` node carrying the file's `package`, then resolve `import com.example.foo.Bar` through that qualifiedName index — so a Bar in Models.kt resolves correctly regardless of filename, a top-level function import binds to its declaration, Java↔Kotlin interop crosses cleanly, and same-name classes across packages no longer collide. Wildcard imports still go through name-matcher.
Also extracts Java/C# anonymous-class overrides (`new T() { ... }`) as first-class class nodes with their override methods. Phase 5.5 interface-impl then bridges T's abstract methods to the anonymous overrides automatically — including the lambda-returned `new T() { ... }` pattern common in guava (Splitter, CacheBuilder).
Concrete impact on macrozheng/mall (524 .java files, multi-module Spring + MyBatis): 524 namespace nodes, 862 imports edges newly resolve to Java symbols, 76 distinct `Criteria` classes preserved across packages with no merge. On google/guava (3,227 .java): 3,608 anonymous classes extracted, +2,534 interface-impl edges reach overrides hidden in `new T() { ... }` blocks.
Agent A/B playbook on small (spring-petclinic-kotlin, 38 .kt), medium (mall, 524 .java), large (guava, 3,227 .java) — 3 flow prompts × 2 runs/arm × 2 arms = 36 runs, claude-opus, headless. Spring repos: 0/0 Read/Grep with-arm, −27% wall-clock vs no-codegraph. Guava: 1.8 Read avg with-arm (vs 2.0 without) — improved by the anon-class extraction; residual is a lambda→SAM coverage gap orthogonal to FQN imports (filing follow-up).
Indexing any C# project produced zero `references` edges, so
`codegraph_callers SomeDto` returned no hits even when the DTO was used
as a param/return type across the codebase, and `codegraph_callees` on
a service class only saw its `using` imports — the headline structural
query silently degraded to text-search on half of every typical backend
stack.
Two root causes:
1. `csharp.ts` was missing `returnField` (default `'return_type'` doesn't
exist on C# AST; the field is `'type'`) AND had
`paramsField:'parameter_list'` (the node TYPE, not the field NAME
`'parameters'`) — so parameter type extraction silently no-op'd.
2. `extractTypeRefsFromSubtree` only emitted refs for `type_identifier`
leaves. C# tree-sitter doesn't produce `type_identifier` — it uses
`identifier`, `predefined_type`, `qualified_name`, `generic_name`,
`array_type`, `nullable_type`, `tuple_type`, etc.
Fix:
- `csharp.ts`: `paramsField:'parameters'`, `returnField:'type'`.
- Route C# through a dedicated `extractCsharpTypeRefs` +
`walkCsharpTypePosition`. Descends ONLY into known type fields
(`parameter.type`, `method.type`, `property.type`,
`variable_declaration.type`, `tuple_element.type`), so parameter
NAMES like `request` in `Build(UserDto request)` never leak as type
refs.
- Hook `extractField` and `extractProperty` to call
`extractTypeAnnotations` so property/field type refs land in the graph.
Validation on dotnet/eShop (527 .cs files):
C# `references` edges: 35 -> 925 (+26x)
No regression in calls/imports/instantiates/extends/implements.
Closes#381.
`pkga.FuncX(...)` cross-package calls in Go monorepos were dropping
through the import resolver — `isExternalImport(go)` flagged any
non-`/internal/` import as third-party because the resolver had no idea
what the project's own module path was. Resolution fell back to name
matching with path-proximity scoring, which on a layered codebase picks
one accidental candidate per call site (~<1% recall per #388's
5,303-vs-1 figure).
- `src/resolution/go-module.ts` (new) parses the `module ...` directive
from project-root `go.mod`, exposed via `getGoModule()` on
`ResolutionContext`.
- `isExternalImport(go)` treats `<module-path>/...` imports as in-module;
the existing `/internal/` escape hatch is preserved for repos without
a parsed go.mod.
- `resolveViaImport` gets a Go cross-package branch that strips the
module prefix to a project-relative directory, then resolves the
qualified member via `getNodesByName(member)` filtered to that exact
directory and `isExported=true`. Sub-packages don't collide with their
parents; same-name funcs in different packages don't false-merge.
- Go extractor sets `isExported` from the identifier's first character
(Go's universal uppercase=exported convention). The resolver depends
on this to filter candidates.
Validation on gRPC-Go (1,031 .go files, layered package tree):
total `calls` edges: 23,803 -> 34,105 (+43%)
cross-pkg `calls`: 10,880 -> 19,929 (+83%)
fmt/strconv/etc. stdlib calls: stay external (no false positives)
Tests cover in-module disambiguation with same-name funcs in two
packages, aliased imports, and stdlib calls not being false-resolved to
in-project nodes.
Closes#388.
Resolves typed member-pointer method calls like `m_cpAlg->Processing()` so `codegraph callers CDetect::Processing` returns the expected callers.
- Extract C/C++ `field_expression` member calls as receiver-qualified references, so `ptr->method()` is preserved as a receiver-aware reference.
- Surface out-of-line C++ method definitions (`int CDetect::Processing() {...}` in `.cpp` with class in `.hpp`) as proper method nodes with the correct qualified identity.
- C++ receiver-type inference: declarator regex requires a terminator after the receiver (rules out matching `return m_cpAlg->...`), handles `Type*x`/`Type *x`/`Type* x` uniformly, and rejects C++ keywords as a final guard.
- `resolveMethodOnType` matches by `Class::method` qualified-name suffix, so out-of-line definitions across files resolve (typical `.hpp`/`.cpp` split).
Validated on bitcoin-core (1306 .cpp files): 38,180 → 40,503 cpp method incoming-call edges (+6.1%), deterministic across re-indexes. Regression test added for the ambiguous-name + `return ptr->m()` / `Type x = ptr->m()` patterns.
Closes#445

Adds tree-sitter-objc extractor for `.m`/`.mm` files and `.h` files
that content-sniff as Objective-C (`@interface`/`@implementation`/`@protocol`/`@synthesize`).
Extraction covers:
- `@interface` / `@implementation` (deduplicated into a single class node)
- `@protocol` (as `protocol` nodes via new `interfaceKind` config)
- Methods with full multi-part selectors (`doThing:with:`, not just `doThing`),
including `+`/`-` static distinction
- `@property` declarations
- Inheritance (`extends`) and protocol conformance (`implements`)
- C-style `function_definition` and `#import` (both `<system>` and `"local"` forms)
- Call edges from both `call_expression` and `message_expression`,
with `self`/`super` skipped on qualified callee names
Two new generic hooks on `LanguageExtractor` (`resolveName`,
`extractPropertyName`) handle the cases where the default name walk
doesn't fit; usable by future languages with similar shape.
Import resolver tries `.h`, `.m`, `.mm` for `objc` imports.
Validated on AFNetworking (84 files, 100% file coverage), RestKit
(282 files, 99.6%), and Texture (926 files, 100%, heavy `.mm`
content) — multi-keyword selectors preserved up to 7 parts, no parse
failures on ObjC++.
Known limitations (disclosed in README):
- Categories produce duplicate class nodes (one per category file)
- Chained/nested message sends record only the innermost method
- `[Class alloc]` patterns don't emit `instantiates` edges
- `@protocol Foo <Bar>` refinement lists not yet wired to `implements`
- Heavy C++ in `.mm` files may parse incompletely under the ObjC grammar
Addresses PHP traits extracted as classes, missing class properties, skipped constants, and invisible trait usage. Adds classifyClassNode to distinguish traits from classes, fixes property extraction for PHP's property_element AST structure (added 4,366 field nodes), and adds visitNode hook for class constants and trait use declarations (increased trait edges from 636 to 1,514). Also improves Liquid schema name handling and file path reference resolution. Verified against Laravel codebase.
Addresses two tree-sitter misparse patterns: (1) fun interfaces with @Throws annotations parse as function_declaration > ERROR instead of user_type, (2) parent interface bodies become ERROR nodes when containing nested fun interfaces, causing methods to be skipped. Updates isFunInterfaceNode to check ERROR-nested user_type children and resolveBody to prefer ERROR bodies starting with `{`.
Addresses Kotlin interfaces/enums extracted as classes, zero function calls, and missing `fun interface` declarations. Adds classifyClassNode to distinguish interfaces/enums from classes, resolveBody hook for non-field grammar, navigation_expression call handling, getReceiverType for extension functions, and visitNode hook to detect `fun interface` misparse patterns from tree-sitter-kotlin's lack of Kotlin 1.4+ syntax support. Verified against Koin and LeakCanary codebases.
Addresses Dart method calls like `obj.method()` and `runApp()` that parse as identifier+selector combinations instead of dedicated call nodes. Adds extractBareCall hook to detect selector nodes with argument_part, handling simple function calls, method chains, constructor calls (new/const), and super/this method calls. Enables proper call relationship tracking for Dart's selector-based call syntax.
Addresses TypeScript abstract classes missing by adding abstract_class_declaration to classTypes. Fixes single-expression arrow functions being silently dropped by preventing extractName from searching identifiers in arrow_function/function_expression bodies, ensuring they return for proper parent name resolution instead of incorrectly using body identifiers.
Addresses arrow function class fields like `field = () => { ... }` where the function body is nested inside field_definition nodes. Adds resolveBody method to traverse field_definition → arrow_function/function_expression → body and handles HOF wrapper patterns like `field = throttle(() => { ... })` by searching call_expression arguments. Enables proper function body extraction for class field functions in both JavaScript and TypeScript.
Addresses Ruby bare method calls like `reset` that parse as identifier nodes instead of call expressions. Adds extractBareCall hook to detect statement-level identifiers that represent method calls, filtering out keywords, literals, and constants. Enables proper call relationship tracking for Ruby's parentheses-optional method syntax.
Addresses Ruby methods inside modules missing owner in qualified_name by adding visitNode hook to extract module AST nodes. Methods inside modules now get Module::method qualified names with proper containment relationships. Includes ExtractorContext wiring with pushScope/popScope for language hooks and updates isInsideClassLikeNode to include module kind for nested method handling.
Addresses C#'s property_declaration nodes (public string Name { get; set; }) by adding propertyTypes support and extractProperty method. Improves field extraction to handle C#'s nested variable_declaration > variable_declarator structure. Adds base_list handling in extractInheritance for C#'s `: Parent, IInterface` syntax where base class and interfaces are combined in a single colon-separated list.
Addresses C++ macros like NLOHMANN_JSON_NAMESPACE_BEGIN that cause tree-sitter to misparse namespace blocks as function_definitions. Adds isMisparsedFunction hook to filter macro artifacts while still visiting their bodies to extract legitimate class/struct/enum definitions hidden inside the misparsed "function" scope.
Addresses C/C++ typedef syntax where anonymous enum/struct definitions are wrapped in typedef declarations (e.g. `typedef enum { A, B } MyEnum;`). Adds resolveTypeAliasKind to identify inner enum_specifier and struct_specifier nodes within typedefs, enabling proper extraction of enum members and struct fields from the inner anonymous definitions rather than treating them as simple type aliases.
Addresses PHP's base_clause syntax for class inheritance (extends) and implements clause for interface implementation. Adds trait_declaration support and separates property_declaration into fieldTypes. Improves PHP method call extraction by handling member_call_expression and scoped_call_expression with proper receiver name processing, including $ prefix stripping and self/this/parent/static receiver filtering.
Addresses Rust's impl block syntax where trait implementations (`impl Trait for Type`) and trait supertraits (`trait Sub: Super`) create inheritance relationships. Adds getReceiverType to extract method receiver types from impl blocks, enabling proper method-to-struct relationships and qualified name resolution. Verified against Deno codebase and moved from "Needs Verification" to completed language support.
Addresses Go's tree-sitter parsing where structs and interfaces are wrapped in type_spec nodes rather than appearing as direct node types. Moves struct_type and interface_type detection from direct node type matching to a new resolveTypeAliasKind resolver that examines the inner type field, ensuring proper extraction with field visiting and inheritance detection.
Adds nameMatchBonus scoring to prioritize results where node names exactly or partially match query terms. Implements dedicated field extraction for Java/C# to properly categorize class fields vs variables. Optimizes BM25 search with column weights favoring name matches and increased result fetching before post-processing. Refines stop words list to preserve common programming terms like "get", "find", "list".
Extends AST parsing to identify and extract individual enum members/cases for better code analysis. Adds enumMemberTypes configuration to each language extractor with language-specific node types (e.g., 'enum_variant' for Rust, 'enum_case' for PHP, 'enum_entry' for Swift/Kotlin). Implements flexible member name resolution supporting both field-based and identifier-based extraction patterns.
Improves search accuracy by boosting results when multiple query symbols appear in the same file, addressing cases where common names like "run" return too many results. Adds Go method receiver type extraction to qualified names for better searchability (e.g., "scrapeLoop.run"). Optimizes database queries with two-pass approach to handle distinctive vs common symbol names efficiently.
Splits the monolithic tree-sitter.ts (3,358 lines) into modular files:
- 14 language config files under src/extraction/languages/
- 3 standalone extractors (Liquid, Svelte, DFM)
- Shared helpers and types modules to avoid circular imports
Also fixes a bug where Java's extractImport hook incorrectly set
handledRefs: true, preventing unresolved reference creation and
degrading codegraph_explore results for Java codebases.
