A member call was read only when its callee ended in the method's name, so
`reflection->GetRaw<RepeatedPtrField<T>>(…)` and
`factory->GetOptions<BlockBasedTableOptions>()` gave the `auto` locals they
initialize no type. Such a call now reaches the class's template overloads,
and when each is declared to return the same one of its own template
parameters (`template <typename Type> const Type& GetRaw(…)`), it returns the
call's argument for it. A macro body's `\`-spliced lines are read as one
statement.

Receiver inference read a declaration a line at a time, so a receiver whose
type began on a line above (protobuf's `const
google::protobuf::internal::ExtensionIdentifier<` over `FeatureSet,
TypeTraitsT, field_type, is_packed>& extension`) or sat alone on the line above
its name (rocksdb's `autovector<…>` over `cf_sv_pairs;`) declared nothing it
could read, and the call fell to name matching. Such a line is now read with
the lines it began on: joined until the template brackets pair, or with the
type line above, as class members already were.

A `nullptr` argument fitted any pointer parameter better than a
`std::nullptr_t` one, which counted as a class, so protobuf's
`ptr.reset(nullptr)` on an `Arena::UniquePtr` took `reset(T*)` over
`reset(std::nullptr_t)`. That `reset(T*)` is declared `= delete`, as is
`RepeatedPtrField::Add(const Element&)`, which `field.Add("foo")` reached.
`nullptr` now fits `std::nullptr_t` exactly and a pointer by conversion, and
an overload declared deleted is taken only when every overload is.

Splitting a call's arguments counted every `<` as a template's, so protobuf's
`p->Emit({{"declare", has_bit_word_index < 0 ? … : ""}, …}, "…")` and
`WriteVarint(num << 3, s)` read as one argument and took the wrong overloads.
A `<` now opens template arguments only right after a name and when a `>`
closes it before the bracket around it does, and the splitter closes the list
at exactly that `>`. A declared type's template arguments now pair their
brackets and may be empty, so `const std::vector<A*>& a, std::vector<B>& b`
and fmt's `parse_context<>& ctx` are read. A line that ends a declaration
begun above, like `std::unique_ptr<Blob>>>& reqs`, still declares the
receiver there.

The line-at-a-time C++ declaration scans took any line starting with `*` for
a comment continuation, skipping rocksdb's `const auto& el =` /
`*reinterpret_cast<std::shared_ptr<EventListener>*>(jhandle);`, and read code
commented out in `/* … */` and the text of string literals (protobuf's
`[[deprecated("Please use SpaceUsedLong() instead")]]`) as declarations.
Block comments are now found in the per-file pass that finds raw strings, and
every scan blanks them, with string contents, before reading a line.

A TEST_F / TEST_P body is a member function of a class derived from its
fixture, so its unqualified names find the fixture's nested types (its bases'
included) before the enclosing namespaces'. And since the index names a
function's local class after the function, every TEST_F body's local `FakeWF`
or `MyManager` shared one qualified name: a class local to a function is now
visible only from inside that function, and a namesake class's methods are
its own body's.

protobuf's `using ConformanceRequestSetting =
BinaryAndJsonConformanceSuite::ConformanceRequestSetting;` names a class the
suite inherits from `ConformanceTestSuite`. An alias was followed only to a
class declared under exactly the name it spells, so constructions through it
stopped at the alias. Its target is now looked up a segment at a time through
each class's bases, as C++ does.

The class-name and capitalized-receiver strategies took any method of the
call's name whose qualified name contained the class's name, so protobuf's
`descriptor->file()` reached `Descriptor::ExtensionRange::file` and rocksdb's
`CompositeEnv::IsInstanceOf(name)` reached `CompositeEnvWrapper::IsInstanceOf`,
while an explicit base call like `PessimisticTransaction::PopSavePoint()`
never found the method the class inherits. In C and C++ a method is now the
class's only when its qualified name is the class's plus the method's, and a
call written through a class asks C++ lookup, bases included.

A class, struct or union whose declaration writes its name in a scope —
leveldb's `struct SkipList<Key, Comparator>::Node { … }`, rocksdb's
`struct BlockBasedTable::Rep { … }` — was indexed as `<anonymous>`, so its
members belonged to no class anyone names and a call on a `Node*` or `Rep*`
was guessed by the method's name. Such a class now takes its own name,
qualified under the written scope the way an out-of-line method is, and its
members are qualified under it, in the TS extractor and the kernel alike. A
specialization (`struct fmt::formatter<Answer>`) stays unnamed: named after
its template, it stood in for the template and every other specialization.
Constructions are recorded by the type's last name, so with `DBImpl::Writer`
named, leveldb's `new log::Writer(…)` in `DBImpl` methods went to it. A C++
construction now makes the class C++ lookup finds for the type as written at
the construction (matchCppConstruction): read with its template arguments
(`new Outer<int>::Inner(…)` makes an `Outer::Inner`), at 0.9, or 0.7 when it
is only the class of that name the file can see; an enum lookup finds; through
an alias the calling function declares, the class it names; and nothing for a
template parameter, a member of a type from outside the project or a local
alias of one. Of several classes or aliases the file declares under one
qualified name (the local classes of separate gtest TEST_F bodies, the members
of unnamed specializations), the one declared around the construction. A `<`
or `>` in parentheses inside template arguments is now read as a comparison.

Overloads of a C++ class's method were told apart by argument count and
string literals only, for a call without a receiver; a call on a typed
receiver always took the first one declared. rocksdb's `db->Get(ro, key,
&value)` reached the five-parameter `Get(…, std::string* timestamp)`, and
`Insert(ch)` on a `char ch` reached `Insert(const std::string& key, …)`.
- cppOverloadFor takes the overloads the count fits best, then the one the
arguments' types fit (cppArgumentTypeFit): a char, number, bool, null or
zero literal; the written type of a name the calling function declares,
of `&name` and of `name[i]`; or an expression's type (cppExpressionType).
The same type scores, as does the same kind of type; a character,
number or pointer for a string, a string or pointer for a number, and a
character or number for a pointer count against.
- cppMethodOf picks among a typed receiver's overloads the same way, of
the class C++ found when namesake classes share its name (leveldb's two
`RandomGenerator`s); a chained call `inner(…).name(…)` keeps the first,
since the arguments at its position are the inner call's.
- cppOverloadParameters reads an out-of-line method's defaults from its
declaration in the class (protobuf's `Printer::Annotate`, whose
`semantic` defaults only there).
- cppOverloadFit: a string literal, raw ones too, counts against a pointer
to anything but characters, a number and a character; comments are
dropped from argument and parameter lists (cppWithoutComments).

Name matching linked C and C++ names to declarations no other
translation unit can name: a class or alias a `.cc` file declares for
itself, its members, and what a source file's unnamed namespace
declares. In rocksdb, other test files' bare `Put(…)`, `Flush()` and
`dbfull()` reached column_family_test.cc's `ColumnFamilyTestBase`
thousands of times, and inlineskiplist.h's `Node*` receivers reached the
`Node` hash_linklist_rep.cc declares in `namespace { … }`.
- isVisibleAcrossFiles rejects such a candidate for a C or C++ ref
(isCppTranslationUnitLocal), as it does a `static` C function: a type
only source files declare; a member written inside such a class; an
out-of-line member of a type the member's own file sees only source
files declare (a scope its file sees no type of may be a namespace:
fmt's posix-mock-test.cc defines posix-mock.h's `test::close` beside
ostream-test.cc's own `struct test`); and, for the rest, what an
unnamed namespace of a source file holds. An alias of the scope keeps
the member, since the class may be declared anywhere.
- A source file's declarations are still seen by the file itself, by a
file that includes it, and by a header it includes below them
(rocksdb's version_set.cc includes version_set_sync_and_async.h after
its `FilePicker` classes).
- The unnamed-namespace spans come from a scanner that skips comments,
preprocessor lines (continued past a CRLF too) and string, character
and raw string literals.
- The typed lookups (cppMethodOf, resolveMethodOnType) take the
candidates the call's file can see first (cppVisibleFirst): rocksdb's
db_stress_shared_state.h and two benchmark `.cc` files each declare a
`SharedState`, and a call in db_stress_common.cc is the header's.

Two gaps in C++ member lookup. In protobuf, `absl::StatusOr<FeatureResolver>
resolver = …; resolver->MergeFeatures(…)` was guessed by the method's name:
the declared type's last name, `StatusOr`, is no class of the project's,
and only std's smart pointers and optional were followed to what they
hold. In rocksdb's typed_cache.h, `using
BasicTypedCacheHelperFns<TValue>::DownCastValue;` makes a bare
`DownCastValue(v)` the base's, but a bare name skipped every base that
depends on the class's template parameters.
- cppHeldType (was cppStdHeldType) also reads `absl::StatusOr`,
`absl::optional` and `absl::NoDestructor` as holders, and
matchCppHeldTypeCall takes one whose name no project type has
(isCppLibraryHolder) — std's holders as before.
- cppUsingDeclares reads the `using Base::name;` declarations a class body
writes. cppScopeMethod and cppInheritedDataMember look a bare name up
in a dependent base when the class brings it in from that base.

The index holds a gtest `TEST_F(Fixture, Name)` / `TEST_P` body as a
function named `TEST_F`; gtest makes it a method of a class derived from
`Fixture`. #2533 gave such a body the fixture's data members
(cppTestFixture), not its methods. rocksdb's tests call `DBTestBase`'s
`Put(…)`, `Flush()`, `Key(i)` and `NewIterator(…)` bare, and those calls
were guessed by name, often reaching a namesake in another class at 0.4
(`ColumnFamilyTestBase::Put`); `auto iter = NewIterator(…)` gave `iter`
no type, so `iter->SeekToFirst()` reached the nested
`MemTableRep::Iterator`.
- cppImplicitThisMethod is #2479's lookup, taken out of
matchCppImplicitThisCall: the caller's class, its bases, the classes
around it, with cppTestFixture as the owner of a gtest body.
matchCppImplicitThisCall keeps the local-shadowing check for the link.
- cppExpressionType types a bare call by the same lookup, as on `this`,
instead of the class's first declaration. Of two classes sharing a name
in different test files it reads the caller's own, and in a template a
dependent base a using-declaration names still counts, as before
(protobuf's `using RepeatedFieldWrapper<T>::MutableRepeatedField;`).
`this` in a gtest body points to the fixture.
- A `->` call on a value of a type from outside the project no longer
takes the type's last name for the class it is in
(isCppArrowThroughOutsideType); the name strategies decide.
matchCppDeclaredTypeCall steps aside for `->` on a value before #2532's
outside-type check, so typing JsonTest's `auto m = ToProto<Any>(…)` (an
`absl::StatusOr<Any>`) had sent `m->value()` to protobuf's own
`hpb::StatusOr::value` at 0.9.

Receiver inference had no type for a name a structured binding declares,
for what a `std::function` returns, or for a class member whose type is
written on the line above its name. rocksdb's MultiCfIteratorImpl writes
`for (auto& [cfh, iter] : cfh_iter_pairs_) { iter->Valid(); … }` over a
member declared across two lines as a
`std::vector<std::pair<ColumnFamilyHandle*, std::unique_ptr<Iterator>>>`;
the calls were guessed by the method's name.
- cppStructuredBindingType reads a binding's type at the name's place: an
element of the range a range-for over the binding iterates, when the
call is in its body, or of a declaration's initializer the calling
function makes, a `std::pair` or `std::tuple` (cppBindingElements). A
map's range elements are pairs of its key and value (CPP_LIBRARY_MAPS).
- cppStatementFrom reads a statement on to its `;`, for a binding's
initializer and an `auto` local's.
- The declarator regex reads `std::function`, `std::move_only_function`,
`std::copyable_function`, `absl::FunctionRef` and `absl::AnyInvocable`
types, whose template argument is a function type, and
cppExpressionType gives a call on such a variable what the function
type returns (cppWrapperReturnType).
- cppDataMemberIn reads a member whose type is the whole line above its
name (CPP_TYPE_LINE), so a default member initializer continued on the
next line (`bool ready_ = flag_ &&` above `it_;`) isn't taken for one.

Receiver inference reads a C++ declaration as a type followed by the
name. What may stand between them was read as the type: in rocksdb's
`Iterator* const iter = iter_guard.get();` the type was `const`, which
names nothing, so the scan went on to an earlier function's `iter`, and
in protobuf's `io::EpsCopyOutputStream* PROTOBUF_NONNULL stream` the
type was a class named `PROTOBUF_NONNULL`. A name an annotation follows
(leveldb's `MemTable* imm_ GUARDED_BY(mutex_);`) was not read at all.
- The declarator regex (and the range-for type tail) reads past a cv-
qualifier or `__restrict` before or after a `*` or `&` (`T* const`,
`T const&`), the nullability annotations after one (abseil's and
clang's, and the ALL-CAPS macros c-cpp.ts already blanks for the
parser), and an ALL-CAPS annotation macro's call after the name.
- matchCppDeclarator hands the readers the type without those
annotations (cppDeclaratorType); cv-qualifiers stay, since what reads
a type reads past them. An ALL-CAPS word counts as an annotation only
after a `*` or `&`, so a type's own name stays (`OS_HANDLE* const h`),
and template arguments are kept as written.
- The call's own file, its same-named header, a class's members and a
range-for's variable are read that way; the local-name check for bare
calls reads past the qualifiers too.
- #2533's test that a method's parameter is no member used `T* const`
locals, which the scan couldn't read; it now declares no local, since
one the scan reads decides first.

Receiver inference read back through the call's file and the header of the
same name only, so a member of a class declared elsewhere — rocksdb's
DBImpl is declared in db_impl.h, its methods in db_impl_write.cc,
db_impl_compaction_flush.cc, db_impl_open.cc and more — was never read, and
calls on it (`versions_->GetColumnFamilySet()`, `mutex_.Lock()`) were
guessed by the receiver's name.
- Where the scan leaves the calling function, the name is looked up as a
data member of the function's class before anything outside it
(cppCallersMember): the class's own declaration lines wherever it is
declared (the declaration in the caller's own translation unit, of
classes sharing a name), then the classes it derives from through their
base edges, skipping a base that depends on the template's parameters.
A gtest `TEST_F` / `TEST_P` body is a method of a class derived from its
fixture, so `db_` there is the fixture's.
- The member goes into the declaration record as the caller's own, with
its class as the lookup site, so #2493's lookup, the library-type gate and
#2440's held-type path apply. A member of a template parameter's type,
or of an alias of one, and a name the scan saw an unreadable declaration
of, stay as before. (isCppTemplateDependentType now also counts a std
trait of a parameter: protobuf's `using MapFieldBase =
std::conditional_t<kIsMutable, …>`.)
- cppDataMemberIn reads only declarations outside parentheses and not
followed by an argument list (method declarations have no nodes, so their
parameters are in the class's lines), skips nested functions and classes,
follows block comments across lines, and blanks string literals.
- A member declared below an inline method that uses it, and a member of
the class itself rather than of a class nested in it, are found the same
way; cppExpressionType's own member fallback became redundant.

#2493 resolved calls on declared pointers, values and references by C++
lookup. Calls whose receiver type came from an initializer or a return
type still went by the type's last name:
- An `auto` local now has the type its initializer has, as written where
that is declared: a cast or smart pointer written out
(`std::unique_ptr<Iterator>(…)`, `static_cast<InstrumentedMutex*>(arg)`),
`new` / `std::make_unique` / a construction of a class, or what a
function or method is declared to return (`txn->GetIterator(…)`), with
the initializer read to its `;` across lines. Its calls then go through
matchCppDeclaredTypeCall from that site. A type that depends on a
template parameter (`T*`, `std::shared_ptr<T>`) is left to the old path.
- A chained call `a->b()->c()` looks `c` up on the class C++ finds for the
written return type of `b`, through a smart pointer too
(matchCppChainOnWrittenType), before the last-name path.
- A type from outside the project gets no project method: a std/abseil
library type (#2413's gate, now applied before the last-name match, so a
namesake class like fmt's own `ostream` no longer wins), and a
capitalized type under a namespace the project declares no type in
(`absl::Status`, which reached `upb::Status::ok`).
- A bare call in a method types an `auto` local from the class's own or
inherited method; a `template <…>` header followed by macros or
specifiers still names its parameters; a trailing annotation macro
(`T* PROTOBUF_NONNULL`) is no part of a return type; and memoized
`auto` types are worked out with a fresh depth budget, so a deep chain
that reads a local first no longer leaves it untyped for its other calls.

C++ receiver inference reads back from a call for a line that declares
the receiver, blanking comments (cppCodeOf) but not string literals. Text
inside one was taken for the declaration:
- protobuf's upb generator emits C code from raw strings:
`GenerateRepeatedSetters(upb::FieldDefPtr field, …)` writes
`upb_MiniTableField field = $field_init$;` inside an `R"cc( … )cc"`,
then calls `field.ctype()` on its own parameter. The scan found the
template's line first, and the call got no edge (a C struct has no
methods).
- rocksdb's log messages read as declarations: `"… in WriteBatch handler;
…"` made `handler` a `WriteBatch`, and `"… remote compaction (…"` gave
`compaction` the type `remote`, so calls fell to guesses by the method's
name.
New cpp-raw-strings.ts reads a file once, when it holds `R"`, as the
compiler does (comments, string and character literals, raw strings with
their delimiters), and keeps the column ranges each raw string takes per
line. The receiver scan, in the file and its header, blanks those and the
contents of the line's ordinary string and character literals before
cppCodeOf. A character literal holding a quote (`'"'`), a digit separator
(`1'000`) and an `R"(` inside a comment don't hide the code after them.

matchCppHeldTypeCall (#2440) returned null (no edge) for a `->` call on a
`std::unique_ptr`/`std::shared_ptr`/`std::optional` whose held class
lacks the method, unless that class is a class template. #2493 found the
gap in the same rule for raw pointers and values: a base the index can't
link may declare the method. protobuf's `class FlatAllocator : public
decltype(ApplyTypeList<FlatAllocatorImpl>(…))` has no extends edge to
`FlatAllocatorImpl`, and rocksdb's `WritePreparedTxnDB` derives from an
alias each `#if` arm declares differently.
Both paths now share one verdict, cppLacksMethod: no class template, and
cppBasesKnown (every base on the way is linked to a class, or is a library
type). Otherwise the call goes on as before.

An import written without an extension that resolved to one file, `./button`
to `button.vue` while `button.ts` was missing, kept that edge and what it
binds when `button.ts` was added beside it, though the resolver now finds
`button.ts` first: sync only retried imports that had failed. A fresh index
links the added file.
When a sync adds a file, the module edges into the files an import of the
same name finds instead (`dir/name.*` under another extension, the folder's
own `dir/name/index.*` or `dir/name/__init__.py`) whose specifier now
resolves to the added file go back to the sweep, and their importers join
the added module's importers with that statement, so the names it binds are
re-resolved too.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
An import statement's own module reference linked nothing in two cases,
even when its bindings resolved through the file: a Vue, Svelte or Astro
component's import (`isJsPathImportRef` covered only the script languages),
and a bare scoped package that a `tsconfig` path or a workspace package maps
to a project file (`isJsPathSpecifier` excluded `@scope/pkg`). So a barrel or
a side-effect module showed no dependency from those files, and sync's
importer discovery, which follows the module edge into a changed file,
never found them when a barrel they import through was deleted or added.
Both now resolve through `resolveImportPath`, as a script's path import
does; an outside scoped package still names no file. Component imports
written with an extension, which a basename match linked before, now link
through the resolver too. When a sync adds a file, it also retries the
failed imports that now resolve to it but wait under no key its path gives:
a scoped package parked under its last segment (`common` for
`@excalidraw/common`, mapped to `packages/common/src/index.ts`, whose keys
are `src` and `index`), under the module ceiling, and an import of the
importer's own folder or the one above (`.`, `..`), parked under no tail.

An `export … from './x'` statement emitted one `imports` reference per
re-exported name and nothing for the module itself; `export * from` emitted
nothing at all. So a barrel made only of `export *` lines had no dependency
on what it re-exports (no dependent for `affected`), and sync could not find
an `index.ts` that re-exports another barrel: when the inner one was deleted
or added, the outer one's importers kept their stale or name-matched edges.
A re-export now imports its module the way `import … from` does, in both
extractors (TS and the Rust kernel): an import node named by the specifier
and a module reference that links the barrel to the file it names. Sync's
importer discovery follows such modules to their own importers, carrying
the names each passes on (`export *`, a named or renamed re-export, an
`export * as ns`), as deep as the resolver chases a re-export; an ES
namespace import reads whatever its module passes on. A re-export's import
node does not count as a symbol for the "parse produced no symbols" warning,
so a barrel with an unparseable line still reports it.

Deleting a module that re-exports what it imports (a package's
`__init__.py`, an `index.ts` barrel) left every file importing through it
linked to the symbols it re-exported: those edges point into files that
stay, so the removal cascaded none of them. When such a module was added or
came back, its importers kept the edges a name lookup had made in its
absence, or stayed failed; and in a large Python project the failed import
of the module itself stayed failed, because the failed-import retry skips a
stem with more than 500 imports waiting (Django's `test`, `models`).
Sync now re-opens, as pending references for its sweep, what the files
importing a removed or added module bind through those imports: before the
removed files are deleted, and after the retries for the added ones (with
their failed references and the module's own failed import). Importers are
found by the import edge into the file, by Python import nodes naming the
module or its package, and through what the module passes on (an import
inside a function has no node); in Python, a package or star import
re-exporting a changed module leads on to its own importers, as deep as the
resolver chases a name. All changed files are handled in one pass, with
importer edges and failed references filtered by the bound names in SQL.
Python and the ES-module family only; no schema or extraction change.

`from fastapi import FastAPI` reaches `fastapi/applications.py` through
`fastapi/__init__.py`, which re-exports it and declares no node named
`FastAPI`. While that `__init__.py` was missing, or before it gained the
re-export, the calls through the name failed and were parked under the
name, which the package file that then appears or changes never carries.
A fresh index linked them; a sync never did.
An unaliased from-import of a module in the project's own folders is now
parked under the module's key, as an aliased one is (#2501): a relative
import, or an absolute one whose dotted path, or the package holding it,
is a project folder at any depth. An outside package's names (`from
django.db.models import Q`) keep their tails, since on netbox they would
crowd 'module:models', 'module:urls' and others past the retry ceiling.
#2450's by-name lookup still finds every parked ref by its own name.
Two limits made the restored package's importers wait anyway:
- A module key gets a retry ceiling of its own, 5,000 rather than the 500
a name tail has. A large population under a module key is every
importer of a package that was missing, not noise: fastapi's 1,069
`from fastapi import ...` refs, Django's 2,257 under 'module:urls'.
- The CG-33 rebind's per-name ceiling counts only the edges that existed
before the retry. Relinking every `from django.urls import path` pushed
`path` over it, so the `path` edges the sync's new definitions moved
were never rebound; the retry's own edges are still rebound under a
name that stays below it, as before.

`from .models import User as UserModel` and `from . import helpers as h`
bind a name their module declares under another: `User`, `helpers`. Every
reference through the alias (the import, a call, a base class, the class
or function passed as a value) was parked under the alias, which no file
a sync adds or changes carries. So a module added after its importers were
indexed, restored after a delete, or given the name in a later edit never
relinked them, while a fresh index did. #2450 fixed the same gap for ES
modules.
Such a reference is now parked under its module's key. A Python import
names its module by a dotted path, counted from the importing file's own
package when it starts with dots: `.models` in app/main.py is
'module:models', `.` is 'module:app', `..pkg` the package above's
'module:pkg'. #2450's lookup still finds it by its own name, which is how
a fresh index links an alias its module never declares. A package's
`__init__.py` also carries the key of the package above it, as a module
file beside it does through its folder, so `from app.pkg import sub as s`
relinks when the subpackage appears.

Receiver typing resolved a C++ call on a variable, parameter or member by
the declared type's last name: `Iterator* iter; iter->Valid()` became
resolveMethodOnType('Iterator', 'Valid'), which takes any class named
`Iterator` that declares `Valid`. facebook/rocksdb has 22 such classes,
and the `Iterator` the code means inherits `Valid`, `Next` and `key` from
`IteratorBase`, so nested namesakes like `MemTableRep::Iterator` took the
calls (google/leveldb's went to `SkipList::Iterator`).
A declaration the calling function or its class writes, called with the
operator it takes (`->` on a pointer, `.` on a value or reference), now
goes through the same C++ lookup #2440 uses for smart pointers'
held types (cppClassWritten from the caller's scopes, then the file's
`using`s, aliases followed) and cppMethodOf (the class's own method, else
one through its own base edges):
- An alias #2399 followed from the caller (function-local typedefs
included) is the class it names, by qualified name. An `auto` loop's
element type (#2492) is looked up where its range's type is written.
- A class found only as the one class of that name the file can see, a
template parameter's type, a library type, or a type nothing visible
declares: the call goes on as before.
- A class with no such method gets no edge, unless it is a class template
or a base on the way is one the index doesn't link (a `decltype(…)`
base, an alias each `#if` arm declares differently), which may declare
it: then as before.
- Declarations read from elsewhere, or past one the scan couldn't read,
are unchanged.
cppClassWritten now tries the file's `using`s before the global scope:
protobuf's upb generator writes `using google::protobuf::Descriptor;`
inside its namespace, and the PHP extension declares a global C struct
`Descriptor` in a header.

#2439 typed a range-for variable when the loop names its type. A loop
over `auto` elements names none, so receiver inference kept scanning as
for an `auto` local with an unreadable initializer: it reached an earlier
declaration of the same name, often another variable's, or fell through
to the guess by the receiver's name. facebook/rocksdb's db_impl_write.cc
loops `for (auto cfd : cfds)` over a `const autovector<ColumnFamilyData*>&`.
The loop's range is now read from its header and typed as written,
template arguments and all, since the index keeps only a return type's
last name:
- a name the calling function declares, or a data member of its class
read from the class's own lines (`versions_` from db_impl_write.cc);
- an `auto` local's initializer;
- `*x`, `x.m`, `x->m`, `this`, and calls whose declaration writes their
return type, free or on the object's class (own or inherited);
- aliases followed with their template arguments (cppAliasedTypeWritten);
- the element: a standard or abseil sequence container's first template
argument, protobuf's RepeatedPtrField and rocksdb's autovector's, or what
a project class's begin() returns, dereferenced (ColumnFamilySet's
iterator's operator* gives ColumnFamilyData*). Nullability annotations
are dropped.
The element goes through the same declaration record as any declared
receiver, so the typed path, #2413's gate for a standard-library element
and #2440's held-type lookup for `->` on a smart-pointer element apply
unchanged. Classes are looked up with #2440's cppClassWritten, methods
through its cppMethodOf, and matchCppHeldTypeCall now reads its held type
through the shared cppStdHeldType.
A/B on main 8a5ba3d0, site-keyed: leveldb identical; fmt +1 / 3
retargeted; rocksdb -68 / +173 / 104 retargeted / 231 confidence only;
protobuf -13 / +25 / 7 / 59. Every removal and retarget was a wrong
guess; 4 of rocksdb's additions reach MemTableRep::Iterator through the
typed path's last-name lookup, as a declared `Iterator* it` does on main.

isBuiltInOrExternal dropped every dotted Go ref whose first segment is in
GO_STDLIB_PACKAGES before any resolution, so a call through a parameter or
local of that name linked to nothing: gin's `context.AbortWithError(…)` in
`func(context *Context)`, harbor's `context.IsAuthenticated()` after
`context := NewSecurityContext(…)` and `log.Errorf(…)` after
`log := log.G(ctx)`, etcd's `printer.DBHashKV(…)` and `trace.Step(…)`.
Such a call now gets past the package list when #2448's scope reader finds
the name declared in the function around it, unless the declaration says it
holds no project method: a type from outside the project or a predeclared
one, or what an outside package's function hands out
(`scanner := bufio.NewScanner(r)`, `url, err := url.Parse(raw)`). #2478's
exemption for locals bound from a type assertion stays beside it.
matchMethodCall resolves these calls by the declaration alone, never by the
receiver's name, which fits dozens of a big tree's types (kubernetes'
`printer := NewTablePrinter(…)` is no kubeadm `Printer`):
- a written or asserted project type (goWrittenType) calls its own method,
an interface's or a promoted one, or nothing;
- a value a project function hands out calls a method of that function's
package: the type named like the variable, or the only one of the name;
- anything else calls only a method no other type declares, never one with
a standard-library method name.
The scope reader also records `x := T{…}` / `new(T)` types and the
own-package function a `:=` calls. GO_STDLIB_PACKAGES moves to name-matcher.
A/B against main 1d3619d6, natural-key edge diffs with identical nodes and
no edge removed: gin +2, prometheus 0, etcd +44, harbor +60, kubernetes
+508, every one triaged correct. The first version, which let these calls
reach name matching, added 811 on kubernetes, 346 of them guesses by the
receiver's name.

isTestPath knew `tests/`, `test/`, `__tests__/`, CamelCase source sets and
`foo-test/` modules, but not the folders LLVM, Clang, clangd, lldb, offload
and Breakpad keep their unit tests in (`unittests/`), nor glog's
`dcheck_unittest/`-style test programs: `/unittests/` holds `tests/` only
after a `t`, and the `foo_test/` form wants a separator right before `test`.
So a helper there with no test-like name (LLVM's CountCopyAndMove.h,
SelectionDAGTestBase.h, Breakpad's dump_analysis.cc) read as production code.
isTestPath now also counts a `unittests/` folder and a `foo_unittest/` or
`foo-unittests/` one. A bare `unittest/` stays production: CPython's
`Lib/unittest/` is the framework, and LLVM vendors googletest under
`third-party/unittest/`.
isTestSuitePath counts the same folders as suites, as it counts `tests/`:
their files build into test binaries and never link into the program, and
glog builds each `foo_unittest/` folder as a test program of its own (a
`foo-test/` module stays out, as shipped test support). That matters for
C/C++ because the suite rule's CamelCase file names skip `.cpp`, so on main
none of LLVM's `*Test.cpp` files were suites and production locals named
`Ctx`, `KV`, `V` or `OpInfo` linked to what a unit test declares.

#2432 made a default import read the module's own `export default`
statement, and its merge pointed #2433's `require('./x').default`
fallback (esmDefaultExport) at the same reading. Nothing in the suite
pinned that path with a guessable helper above the default: #2433's
fixture keeps its helper unexported.
Two cases:
- React Native's AnimatedColor shape, an exported helper above
`export default class AnimatedColor`, loaded with
`require("./AnimatedColor").default` and
`const { default: Color } = require("./AnimatedColor")`. With the
first-exported guess both `new` calls instantiate the helper.
- `export default abstract class Repository` below an exported
`connect()`, extended by `class Users extends Repository`. With the
guess the `extends` edge is missing.
Both fail with e47cb258's resolver (before #2432). On main, putting the
guess back on the require path fails only the first, and dropping
`abstract` from the declaration pattern fails only the second.
The CHANGELOG's default-import bullet now says `require('./x').default`
is read the same way.

A data-router `lazy` loader resolves to the route's properties, and many
pick their page from the module they load: luci-go milo/ui's
`lazy: async () => { const { TestTab } = await import('…/tabs'); return
{ Component: TestTab }; }`, `const { default: Component } = await
import('./pages/Login')`, `import('./x').then((m) => ({ Component: m.Page }))`,
`({ Component: (await import('./x')).Page })`, React Router 7's
`lazy: { Component: async () => (await import('./x')).Page }`. scanRoutes
recorded only the first `import('…')` as `lazy-import:<spec>`, and
resolution linked the module's default export, else its `Component`: a
different page, or nothing (milo/ui's tabs barrel has neither).
lazyRouteReference reads the loader: its `Component`, or the page its
`element` shows, followed through the loader's bindings (destructured
`await import`, a module binding, `.then` callbacks, `Promise.all`, the
v7.5 object form), and the one lazily imported export a guard shows
(`<AgeGate><FireworksPage /></AgeGate>`). A loader that returns the module
keeps `lazy-import:<spec>`; one this does not read (a helper's, `.then(convert)`)
keeps its first import, as before; one that hands over only a `loader`
renders nothing. `async lazy() { … }` methods, which scanRoutes skipped as
entries, are read too, and comments no longer hide an import's specifier.
The picked export is named the way Vue Router and Angular name a lazy
component, `import:<path>#<export>`, so sync's module-tail retry (#2422)
parks and retries it unchanged, and it resolves through #2436's
exportedComponent, barrels included. React is registered before Vue Router
and Angular, so it answers only its own routes' references (tsx or jsx,
which theirs never are). lazyModules (#2452) names the files a picked
export is read from, so a sync that moves it redraws the route.

A C++ call written with no receiver, or through `this->`, inside a method
was matched by its name alone, so another class's method of that name won
by file proximity: protobuf's generated `Api::operator=` calling
`InternalSwap(&from)` reached `Any::InternalSwap`, `Any::InternalSwap`'s
inherited `GetArena()` reached `Arena::InternalHelper::GetArena`, and
googletest's `~linked_ptr() { depart(); }` reached `linked_ptr_internal::depart`.
matchMethodCall now resolves C++'s implicit `this` the way it resolves a
typed receiver: the calling method's class, then the classes it derives
from (its own base edges, through #2440's cppMethodOf), then the classes it
is nested in, with the overload the arguments fit. The call's shape is read
at its column (the extractor drops `this->` and some receivers it can't
spell). A free function, a parameter or local of the name, a dependent base
reached by a bare call, a namesake class in another translation unit and a
member a macro may declare all leave the call to the name strategies.

Receiver inference read `v := T{}`, `var v T` and parameters, never a
local bound from a type assertion. So `flusher.Flush()` after
`flusher, ok := w.(http.Flusher)` went to whichever project method name
matching picked, and calls like etcd's `fi.Action()` after
`fi := s.kvindex.(*fakeIndex)` linked to nothing.
A Go local whose declaration in scope at the call binds the value of a
type assertion (`v := x.(T)`, `v, ok := x.(T)`, `var v, _ = x.(T)`) now
has the asserted type, found where Go finds it, as #2444 does for a call
made through the assertion itself (`x.(T).M()`). Calls, method values and
field chains through the local (`wr.job.Start()`) reach the type's own
method, its interface's, or one embedding promotes into it. The binding is
the one the scope reader from #2448 finds in scope at the call: an `if`
header's ends with its statement, and a nearer declaration in a block that
has ended does not hide it. A type switch's variable and a value that only
starts with an assertion (`x.(T).field`) resolve as before.
A type from outside the project, a predeclared type or an alias of an
outside type links nothing, as for the assertion itself. A type the index
can't tell is left to name matching, as before: a type literal
(`interface{ GetDeadline() time.Time }`) or a type declared inside a
function (grpc-go's `internalInfo` and `grpcstatus`). A local bound from an
assertion and named like a standard-library package
(`parser, ok := builder.(balancer.ConfigParser)`) is no longer dropped as
a call into that package.
On etcd, harbor, kratos and grpc-go, 358 call sites change. 216 gain a
link, 38 move to the asserted type's method and 89 keep their target, now
resolved through the asserted type. 15 lose a link that went through a
type from outside the project, or from a field read to a same-named
function.

The jsx-render pass read a tag's name only where whitespace, `/` or `>`
ended it, so a generic component's tag, whose type arguments follow its
name, was never read: outline's `<PaginatedList<Document> items={…} />`
and excalidraw's `<DropdownMenuItemContentRadio<"contain" | "overlap">`
left the parent with no edge to the component it renders. The tag pattern
now also ends a name at `<`, as a lookahead, so that `<` still opens the
next match, which `opensTag` (#2442) reads as a type argument, not a tag.
This lands after the package-import gate for JSX tags (#2475). On main alone the
same change also linked 5 package tags to project namesakes by name
(refine's react95 `<Select<number>>`, antd `<Table<IPost>>` and
`<Form<ILoginForm>>`; signoz's antd `<Form<…>>` ×2 to a styled `Form`),
which the gate declines.
Fresh before/after indexes with the gate as the base: 22 jsx-render edges
added and nothing else changed (outline 10 to `PaginatedList`, signoz 8,
excalidraw 2, mastodon 2). Each target is what the file's import or own
declaration binds, checked with the TypeScript checker with module
resolution. refine-examples, bulletproof-react, mantis, proshop_mern,
next-saas-starter and create-t3-turbo are byte-identical.

A JSX tag the file imports from a package (antd's `<Button>`, react-router's
`<Link>`, `@mui/material/Typography`'s default) renders that package's
component, which the index does not hold. `jsxChild` took a project node of
the same name anyway: a unique name without looking at the file's imports at
all, and a repeated one by language and order, because a package import never
resolves to a file. On SigNoz, antd and @signozhq/ui `<Button>`s rendered
`export const Button = styled(Link)` from a 404 page's styles.
- `jsxChild`: a component the file declares itself still comes first. Then a
tag the file imports from a package binds nothing: the import's specifier
passes `ctx.isOutOfRepoImport`, the test the name matcher applies to calls
and values (no project file answers it, and a package.json on the file's
way to the root declares it). An alias that reads like a package
(`components/Modal`), an undeclared bare specifier and a workspace package
keep the old rules.
- Vue templates (`vueTemplateEdges`'s `resolve`): the same rule for a
PascalCase or kebab-case tag, a handler, and the composable a destructured
handler comes from. A package-imported tag no longer falls back to a Nuxt
auto-imported component either.
Fresh before/after indexes of 35 repos on main b635dd46: 6,550 jsx-render
edges removed, and one added: a same-file component (refine's win95
`AddButton`) that the 30-children cap had crowded out. A script that reads
each parent's import and the package.json chain, independent of the
resolver, confirms every removed edge is a tag imported from a declared
package. Nodes, refs, files and every other edge are unchanged, and 13 React
and 5 Vue repos are byte-identical.

A C++ call made with `->` on a receiver the calling function or its class
declares as a `std::unique_ptr<T>`, `std::shared_ptr<T>` or
`std::optional<T>` now resolves on `T`: on the class C++ name lookup finds for
it where the call is written, or on a class that class derives from. Before,
receiver inference read the type as `unique_ptr`, found no method, and the
call fell through to the guess by method name: rocksdb's
`std::unique_ptr<Iterator> iter; iter->Valid()` reached
`ArenaWrappedDBIter::Valid`.
The held type goes through #2407's lookup (`cppClassWritten`, extracted from
`matchCppSupertype`), not `resolveMethodOnType` on its last name: rocksdb has
22 classes named `Iterator`, and the one the calls mean inherits its methods
from `IteratorBase`, so a last-name lookup reaches `MemTableRep::Iterator`.
The method is taken from that class or its bases through the class's own
extends edges (`getSupertypeNodes`). A template parameter, a library type or
an alias of one gets no edge; a type the project doesn't declare, or an alias
the lookup can't follow, leaves the call as it was.
The namespace-macro helpers move from name-matcher.ts to cpp-namespaces.ts
unchanged, so name-matcher can import cpp-supertypes without a cycle.

A default import resolved to the module's first exported function or
component whenever the `export default` statement wrote a declaration
(`export default function Vans()`, `export default class Store`): only a
separate `export default NAME` statement was read. A React Router 6.4+
data-router page exports its `loader` or `action` above the page
component, so `import Vans, { loader as vansLoader } from './Vans'` bound
the route `/vans` (and every call through `Vans`) to `loader`.
The resolver now reads the file's own `export default` statement from
comment-stripped code. A declaration it writes is found by position, a
binding it names by name, and an anonymous function, class or arrow
function is no node at all (the guess took an exported function beside it,
or one nested inside it). The statement also beats an exported styled/memo
component above it. Every line-initial statement is read and the first one
that names a node of the file wins, so template text that only reads like
a statement names nothing. Strings are not masked: a masker loses step on a
template whose `${…}` holds another template or a regex with a backtick,
and on outline it blanked the real statement below one. Only an expression
default (`memo(Card)`, `new Service()`), a binding the file doesn't
declare, or no statement keeps the old guess.
`require('./x').default` (#2433) reads the same statement first, so it
reaches the declared default too.

C++ receiver inference read a declaration only when the declared name was
followed by `;`, `=`, `,`, `)`, `[`, `{` or `(`, so a range-based for's
`Type name :` was never read. In protocolbuffers/protobuf's conformance
runner, `suite->SetVerbose(…)`, `suite->RunSuite(…)` and
`suite->GetFailureListFlagName()` inside `for (ConformanceTestSuite *suite :
suites)` fell through to Strategy 3's guess by the receiver's name, and in
RocksDB `log->file()` on a `log::Writer` loop variable went to
`BlobLogWriter::file`.
A line the declarator regex doesn't match is now read as a range-based for
when its `for (` header declares the receiver before a single `:` (not
`::`), and the loop's variable is taken only when the call is inside the
loop's body: past the header, up to the `}` closing a braced body or the end
of a single-statement body, with comments and literals skipped. After the
loop, or in a later function, the same name is another variable, and the
scan goes on as before. A loop over `auto` elements has nothing to read and
keeps the existing fallback. Bit-fields and the scope operator are never
read as a loop's declaration.
A loop's declaration is recorded like any other (#2413's
noteCppDeclaration), so the std-type gate applies to
`for (const std::string& s : …)` too, and a loop that doesn't enclose the
call still marks the receiver as shadowed. With #2421, the 13 conformance
runner calls reach ConformanceTestSuite's methods at 0.9.

A route that renders `const Docs = lazy(() => import('./pages/Docs'))` binds
to the component that module exports, and to the declaration while the module
is missing or exports none (#2400's declaredComponent). The reference had
resolved, so no failed-ref retry saw it, and CG-33's rebind reached it only
when the module's component shared the declaration's name: a sync that added
the module, gave it its default export or moved that export left the route
on its old answer. A data router's `lazy` route kept a moved default export
the same way.
FrameworkResolver.lazyModules names the modules a route's answer reads,
including the files a barrel forwards it through (#2436); React implements it
for lazy-import references and the same-file lazy values Pattern 1 reads.
After the CG-33 rebind, sync puts back the route references whose modules it
added or changed (reopenRouteModuleReaders), in the order their edges were
written, for the orphan sweep.
The jsx-render refresh read only each changed file's own content, so a new
component without JSX of its own never got the edge from `<Team />` in an
unchanged file. A sync whose definition delta holds a JSX-renderable node now
refreshes synthesis.

Two surfaces label a synthesized (dynamic-dispatch) `calls` hop:
codegraph_explore's Flow and dynamic-dispatch links plus the
codegraph_node trail (`dynamic: interface → impl @file:line`), and
ContextBuilder's "## Call paths", which `codegraph context` prints
(`→[…]`). Each kept its own list. The call paths' list stopped at
callback, react-render, jsx-render, vue-handler, http-client, queue-job
and socket messages, so every other synthesizer fell through to
`event ${m.event ?? ''}`: an interface-impl hop read
`→[event @src/pdf-exporter.ts:5]`, and so did a C++ override, a redux
thunk, a gin middleware chain or a closure collection.
The wording now lives once, in src/graph/synthesized-hop.ts
(`describeSynthesizedHop`: a summary, the detail only the call paths
print, and the wiring site), as AGENTS.md asks of a derivation two
surfaces render. ToolHandler renders `dynamic: <summary> @site`, the
call paths `<summary><detail> @site`. Explore and the node trail print
exactly what they printed before; the call paths keep their wording for
the kinds they already labelled, including the queue name, a socket's
direction and the HTTP clause, and now name the rest the way explore
does. A bus event reads `bus event` there too, and the section's
footnote no longer says hops are marked `[callback/event …]`.
The helper also holds the wording #2414 gives a Go method a struct gets
by embedding (`metadata.promotedInto`), so that arm moves here too. The
unused long `label` form of ToolHandler.synthEdgeNote (last read by the
removed codegraph_trace) is dropped.

tree-sitter-go puts the comment above `type Foo struct{}` before the
`type_declaration`, but the node is made from the spec inside it, so both
extractors found no docstring for an ungrouped struct, interface, defined
type or alias. A type inside a `type ( ... )` group kept its own comment,
which sits beside it in the parentheses.
Go's docstring is now read from the declaration when the declaration
holds one spec and nothing precedes that spec inside it. The leading
comment of a group with several members stays the group's.
Reading from the declaration exposed comments that trail the line above:
`const _ = proto.GoGoProtoPackageIsVersion3 // please upgrade the proto
package` would have become `type MetricType int32`'s doc. For every Go
declaration, a comment that begins after code on its line, and one that
begins on the line such a comment ends, is now left out, as go/parser
reads them. Seven function docstrings on etcd and prometheus lose one.

A default, namespace or aliased import binds a name its module never
declares: `import tagsController from './tag/tag.controller'`,
`import { Component as GroupsPageWrapper } from './groups_page'`. Every
reference through that name (the import, a call, `new`, a base class, a
JSX or template tag, an Express mount) was parked under the name, which
no file a sync adds or changes carries. So a module added after its
importers were indexed, restored after a delete, or given its export in a
later edit never relinked them, while a fresh index did.
Such a reference is now parked under its project module's key
(`module:tag`), which sync already looks up for every file it adds or
changes (#2422), and it is still found by its own name: a binding its
module never resolves is linked by that name alone, as vben's
`{ VbenFormSchema as FormSchema }` from a workspace package is. Schema
v15 adds the partial index that by-name lookup needs; its leading
`status` keeps the planner off idx_unresolved_status, which read 830K
rows on vscode's index.

`const Wrapper = styled.div<WrapperProps>` + a template literal came out as a
`constant`, so the JSX-render synthesizer skipped it: `<Wrapper>` got no
render edge, or bound to a same-named component in another file.
tree-sitter's tagged-template call takes no type arguments, so when the type
argument also reads as an expression the initializer parses as comparisons,
`(styled.div < WrapperProps) > template`, not as a call. (A type argument
that can't be an expression, `<{ open: boolean }>`, error-recovers into a
call on the tag, which #841 already took.)
reactComponentHoc now also takes that comparison chain: the leftmost operand
is the `styled` tag against a `<`, the rightmost is the template against a
`>` (`>>` when the type argument ends in its own `<...>`), and operators in
between belong to the type argument (`<A & B>`). Mirrored in the kernel's
TS/JS walker.

The resolver's name-existence pre-filter read no leading `::`: its `::`
branch wanted the separator past the first character, and the single-`:`
loop skips names holding `::`. So `::leveldb::RepairDB(…)`,
`::ROCKSDB_NAMESPACE::RepairDB(…)` or protobuf's `::_pbi::…` calls were
dropped before any strategy ran, unless a detected framework claimed them.
protobuf's got through only because it ships three Swift files: the
Swift ↔ Objective-C bridge claims any name with a `:` in it, which is why
#2415 left claimsReference() universal.
- The pre-filter checks a C or C++ name without its leading `::`.
- claimsReference() is asked only of the frameworks that resolve the
reference's language (frameworksFor), like resolve() since #2415.
- matchByQualifiedName takes a global-qualified C/C++ name as exactly
that qualified name. Its suffix match took a namesake nested in another
namespace or class: with the pre-filter alone, 23 of the 24 edges it
added on leveldb, fmt and rocksdb were wrong, mostly wrappers like fmt's
mock `test::open` linked to the `::open(…)` they wrap, and protobuf's
`::operator delete` went to `DynamicMessage::operator delete`. A
declaration inside a namespace a macro opens (fmt's `struct pipe`) only
looks global in the index, so it is skipped; step 5 still reads those.
- `::std::…` and `::memset` count as `std::…` and `memset` for the
built-in check, and step 5 returns early for a single-segment name.

`struct Foo { … } foo;`, `class Bar { … } bar;` and `static struct { … } SPT;`
outside any function or class body went to the variable extractor, which
skipped the declaration's children, so the type, its methods and its
enumerators were never indexed in either extraction engine.
Both engines now walk such a type before the variables: in C always, and in
C++ when the tree has no errors or the file is walked in brace scopes. This
converges with #2426's walk for erroring C++ files; a C++ file whose braces
don't balance is still left alone, since error recovery can run a class past
its own `}` there. The declaration's function-as-value scan skips the walked
type, which captured its own. An unnamed struct, union or enum takes the name
of the first variable its declaration declares (also inside function bodies,
where it was `<anonymous>`), as `typedef struct { … } Name;` already takes the
typedef name, and the comment above the declaration is the type's docstring.
cDeclaratorIdentifier moves to languages/c-cpp.ts.

Explore's named walk is breadth-first, and the first callee listed claimed
each node it reached. An interface method calls every implementation at the
same depth, so when several of them call the next named symbol, the Flow went
through whichever implementation the index listed first, even when the query
named another one. On prometheus, `Engine.execEvalStmt Queryable.Querier
fanout.Querier NewMergeQuerier` went through the TSDB's `DB.Querier`; on gin,
once defined types count as implementers, `setter.TrySet` went through
`headerSource.TrySet` when the query named `formSource.TrySet`.
A node reached again from the same depth now takes the route that ends on
fewer unnamed hops, then the one through more named symbols, and keeps the
first otherwise. Of two equally deep named ends, the seed keeps the one whose
route passes more named symbols. The expansion order, the visited set and the
NAMED_VISIT_CAP bound are unchanged, so the walk makes the same callee lookups.

normalizeCppTypeName cut each `<…>` at its first `>`, so a declared type
with template arguments nested in its template arguments kept debris:
`autovector<std::pair<int, FileMetaData*>>` read as `autovector >` and
`Striped<CacheAlignedWrapper<port::Mutex>>` as `Striped >`. No class has
such a name, so the call was never resolved on the receiver's class. A
capitalized debris name made isUndeclaredTypeName take the type for an
outside one and silence the call (rocksdb's `mutex_.Get(key)`), and a
lowercase one fell to a guess by the receiver's words (rocksdb's
`files_marked_for_compaction_.clear()` reached `CompactionInputFiles::clear`).
Template arguments are now stripped with their nesting by
cpp-type-aliases' depth-tracking helper, exported as
stripCppTemplateArguments; cpp-supertypes' identical private copy now
imports it. A `>` that closes no `<` is the end of a declaration begun on
an earlier line (`std::unique_ptr<BlobContents>>>& blob_reqs` under
`autovector<std::pair<…,`): a depth strip alone would read the argument's
type there, so such text names no type. The scan back to the receiver's
declaration then marks it shadowed (#2413), as it does for a declaration
whose type it can't read, so a member or earlier variable of the same
name found further up doesn't decide the call.

goImplementsEdges matched method names only, so a struct whose same-named
method takes or returns a different number of values, which Go can never
accept, was linked as an implementation (etcd's watch cache as a
peerGetter), and enough such look-alikes filled the per-interface cap
before the real implementer (grpc-go's xDS TransportBuilder).
Each wanted method now also needs a declaration with its parameter and
result counts, read off the stored signature text; a signature that
doesn't read rules nothing out. A gRPC client interface (every method
takes `opts ...grpc.CallOption` last) also accepts its RPCs' server
arities, so `KVClient.Range -> kvServer.Range`, the bridge explore
follows from a client call to its handler, stays. Defined types (#2419)
are held to the same counts.

A data router's `lazy: () => import('@/pages/invocation_page')` loads the
folder's `index.ts`. When that file only forwards the page, with
`export * from './invocation_page'`, `export { default } from './page'` or
`export { Page as Component } from './page'`, the route linked nothing: the
module was read for an export of its own and none was found. The lookup now
follows the module's re-exports a few hops to the file that declares the
page, the way JavaScript resolves them (`export *` never forwards the
default, a name two `export *` modules both forward is exported by
neither), and reads a module's own `export { Page as Component }` clause.
`React.lazy` values in a route file, which go through the same lookup,
follow such barrels too.
On luci-go's milo/ui, 51 of 91 failed lazy route refs now link; the rest
load a file under `src/build/` (not indexed), export only a `loader` or a
`handle`, or pick a named export in an async loader. Sync links a page
added or edited behind its barrel the way a fresh index does.

A Go defined type (`type WatchChan <-chan WatchResponse`, gin's
`type HandlerFunc func(*Context)` and `type HandlersChain []HandlerFunc`)
is a `type_alias` node, and it referenced nothing: only an `=` alias
(#2417) named the types on its right-hand side. Impact on
`WatchResponse` or gin's `Context` missed the declarations built from
them, and everything that uses those.
Fix (TS extractor and the Rust kernel, mirrored): goAliasTypeNames /
alias_type_names walk the `type` field of every type_alias node, a
defined type's as well as an alias's, so each type it names becomes a
`references` ref on that name, where resolution reads the package
qualifier back. Still skipped: the declaration's own type parameters,
Go's predeclared types, and now its own name written bare, which in a
recursive type (prometheus' `type stateFn func(*Lexer) stateFn`) is the
declaration itself: no self-edge, and no failed row that would make
dead code treat every namesake as referenced. A qualified name is never
skipped (`type PutResponse pb.PutResponse` names pb's).
Resolution is unchanged. A defined type is a new type: goAliasTarget
still follows `=` aliases only, so a method called on a defined type
is not looked up on its underlying type. The gateTargetKind rule that
leaves a type_alias's reference written through a package the index
doesn't know unresolved now covers defined types too; without it, every
such name bound to the same-file declaration of its name (`type Op
clientv3.Op` linked itself).
