… type of its range (colbymchenry#2492) colbymchenry#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, colbymchenry#2413's gate for a standard-library element and colbymchenry#2440's held-type lookup for `->` on a smart-pointer element apply unchanged. Classes are looked up with colbymchenry#2440's cppClassWritten, methods through its cppMethodOf, and matchCppHeldTypeCall now reads its held type through the shared cppStdHeldType. A/B on main 8a5ba3d, 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.

…e class its type names, not a namesake (colbymchenry#2493) 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 colbymchenry#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 colbymchenry#2399 followed from the caller (function-local typedefs included) is the class it names, by qualified name. An `auto` loop's element type (colbymchenry#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.

…ears later (colbymchenry#2501) `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. colbymchenry#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'. colbymchenry#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.

…for and declared-type receivers Ports upstream's C++ auto range-for element typing (colbymchenry#2492) and declared-type receiver lookup (colbymchenry#2493) into the native resolver, and takes the Python import-alias sync retry (colbymchenry#2501). The deleted TypeScript resolver files stay deleted. Three upstream assertions that expect a name-based guess are adapted to the fork's no-guess policy: a call on a template-parameter-typed receiver stays unlinked, a known class without the method gets no namesake fallback, and the text scan's existing earlier-function local read is unchanged.

A type written `::Registry` is looked up at global scope, not in the classes around the code. Overloads that take different parameters and return different types give no element type, since which one a call picks is not read; a const and non-const pair with the same parameters still gives one. In the line scan, a nearer declaration of the receiver inside the loop body hides the loop's variable.

Merges upstream

import-resolver.tsby hand next to the fork's external-import check. The upstream test passes unmodified.autoelements has the element type of its range colbymchenry/codegraph#2492 (for (auto x : container)element type) and fix(cpp): a call on a declared pointer, value or reference reaches the class its type names, not a namesake colbymchenry/codegraph#2493 (receiver declared as a project class): the fork deleted upstream's TypeScript resolver, so both are ported to the Rust kernel. Newcpp_range_for.rs, plus changes tocpp_receivers.rs,receivers.rs,cpp_aliases.rs,cpp_implicit_this.rs.name-matcher.ts,cpp-supertypes.ts,cpp-type-aliases.tsstay deleted.Differences from upstream tests
Three assertions in
cpp-declared-type-receiver.test.tsare changed, each with a comment: a template-parameter receiver stays unlinked, a known class without the method gets no name-only fallback, androcksdb::Stepstill reads an earlier function's local through the older text scan (fixing that cost about 115 correct rocksdb links). One regression test is added to each of the two C++ test files.Evidence
The 5 lost rocksdb links were wrong before (name-only matches); 30 of the gained links were checked against source and were correct. Full suite: 694 files, 8878 passed, 39 skipped, no worker crash lines. Kernel tests 67 passed. Golden dumps unchanged. Precision: json 11/11 absent held and 7/7 present held; jq has no cases. The gtest example in the CHANGELOG fork note is reasoned from the code path, not measured.

mainthrough5171a6aaintofork/consolidated, unblocking the hourly deploy timer that upstream has been holding back since4d15b680. It takes three upstream fixes: C++ range-for-over-autoelement typing (colbymchenry#2492), declared-type receiver lookup (colbymchenry#2493), and the Python import-alias sync retry (colbymchenry#2501).Ported fixes
