- Around line 2596-2609: Update the object_creation_expression handling in the
graph-symbol extractor to mark creation edges with their type name as the callee
qualifier, then update the C# branch in resolveCallSites to recognize these
creation edges and resolve either the explicit constructor or the class-like
symbol. When qualified lookup finds no match, use the project-wide csTypesByName
index so same-namespace types outside the dependency graph resolve.
- Around line 2632-2636: Update the identifier loop around safeFindAll and
pushTypeRef so every identifier in a nested qualified_name qualifier is skipped,
while the terminal type identifier is retained. Determine qualifier membership
by comparing node ranges and walking through enclosing qualified_name nodes,
rather than comparing identifier text; add a focused helper near
csTypeHeadIdentifier and use it in the loop.
- Around line 2566-2594: Update the C# member-access handling in the
invocation_expression loop to preserve the qualifier for namespace-qualified
calls such as Namespace.Calc.Compute(). Handle a member_access_expression
receiver by extracting its type-head identifier and using it as calleeQualifier
when it begins with an uppercase letter; retain the existing identifier and
generic_name behavior.

…d types Review of giancarloerra#209 at ee109c5 found the C# edges still lost identity the source writes out: - A namespace-qualified call (`Billing.Calc.Compute()`) emitted a bare `Compute`, and a qualified type (`Billing.Calc`) a bare `Calc`, so both bound local-first to a same-named declaration. Calls and type references now carry the whole written path as `calleeQualifier`, and every C# symbol its namespace-qualified `csFullName`; resolution matches the path against the full name's trailing segments. - `new Calc()` took the generic path and stayed unresolved outside the file graph. A creation now carries the type path as its qualifier (a member cannot share its class's name) and resolves to the declared constructors, or to the type when it declares none. - Qualifier segments were skipped by text, which emitted `Collections` for `System.Collections.Generic.IList` and dropped the terminal of `Order.Order`. They are now identified by byte range. - The framework-name filter dropped a project's own `Task` at extraction. Framework names are now recorded and marked `engine` at resolution only when no project type matches. - Owners came from line numbers, so two classes on one line shared members. Owners and full names now come from range containment. - Delegates (`type`) and properties (`variable`) are recorded, as giancarloerra#208 asks. A member-access receiver may end in static members (`Config.Instance.Load()`), so `csMemberReceiver` lets resolution fall back to the longest prefix that names a type; a type position is matched whole.

…evidence `csMemberReceiver` let `Billing.Rates.Load()` fall back to any class named `Billing` when the whole path named no type, although `Billing` may be a namespace the project does not declare: the same-named binding giancarloerra#209's review asked to rule out. A shorter prefix is now accepted only for a type that declares the next segment: a member symbol with that full name, or a name in the type's new `csMembers` (fields, constants, events, enum members, which are not symbols). Otherwise the edge stays unresolved. `UserStatus.Active.Id` (a static readonly field) still resolves; `Site.GroupSiteId.ToString()` narrows from four classes named `Site` to the one that declares it; a `using` alias such as `Fixture.Supplier` no longer binds unrelated nested `Fixture` classes.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Fix the null qualifier check. With the current ??, the extern-alias guard never runs.
written stores null for a path that is not a plain name path. Two cases do this: an extern alias such as Ext::Foo, and a qualifier rooted in one, such as Ext::Ns.Foo. The comment at Lines 2534-2536 says that no reference is drawn for these cases. writtenQualifier returns written.get(...) ?? "", and ?? converts the stored null to "". The qualifier === null check in pushTypeRefAt at Line 2759 therefore never succeeds. Foo is then emitted as a bare type_reference. The resolver's project-wide find binds a bare Foo to any project type of that name and can report it as unique.
Separate a missing key from a stored null.

…, creation and qualified-call edges
The C# extractor named every declaration by the first identifier under it, which
is an attribute or a return type whenever one precedes the name: on a 19 000-file
solution 48 551 symbols were recorded as `Fact`, 22 044 as `Task`, 1 730 as
`HttpGet` and 859 as `ApiController`. It captured only `invocation_expression`
edges, so no class, interface, record, struct or enum could ever be a dependent,
and `extractCalleeInfoJs` kept the last segment of `A.B.C(`, so a static call
`Other.M()` was answered by a same-named `M` in the caller's own file.
- Declarations are named from `field("name")`, with the first identifier as the
fallback; `enum_declaration` is extracted; members carry `Owner.Name` as their
qualified name.
- Invocations through a `member_access_expression` whose receiver is a PascalCase
identifier carry it as `calleeQualifier` (`this`, `base` and fields do not).
- `object_creation_expression` is a call to the type, as `new Foo()` is for
TypeScript, and a `type_reference` to it.
- `type_reference` edges for base lists, parameter / field / property / local /
return types, type arguments, `typeof`, casts, attributes (`[Foo]` names
`FooAttribute`) and the receiver of a qualified member access — the C#
counterpart of the import edge a TypeScript `import { Foo }` gives a class,
since `using` names only a namespace. BCL names are left out, as
`TS_BUILTIN_TYPES` does for TypeScript.
- Resolver: a C# edge with a qualifier is matched by `Owner.Name`, a C#
`type_reference` by name against class-like symbols — in the caller's file,
its dependencies, then the whole project through two lazily built indexes,
because a same-namespace target needs no `using` and is outside the file
graph. A name no class declares stays unresolved.
Measured on the same solution, same commit: unresolved symbol edges 94.2 % →
62.6 % (the rest are BCL and LINQ calls); the four misnamed buckets above are
gone; `codebase_impact` on a static helper class 0 → 5 files at depth 1, and its
caller list names every file `git grep` finds except one whose only mention is
a comment; on one of its methods, previously recorded under its return type's
name, 0 → 4 files; on a widely shared class, 0 → 164 files.
Review of giancarloerra#209 at ee109c5 found the C# edges still lost identity the source writes out: - A namespace-qualified call (`Billing.Calc.Compute()`) emitted a bare `Compute`, and a qualified type (`Billing.Calc`) a bare `Calc`, so both bound local-first to a same-named declaration. Calls and type references now carry the whole written path as `calleeQualifier`, and every C# symbol its namespace-qualified `csFullName`; resolution matches the path against the full name's trailing segments. - `new Calc()` took the generic path and stayed unresolved outside the file graph. A creation now carries the type path as its qualifier (a member cannot share its class's name) and resolves to the declared constructors, or to the type when it declares none. - Qualifier segments were skipped by text, which emitted `Collections` for `System.Collections.Generic.IList` and dropped the terminal of `Order.Order`. They are now identified by byte range. - The framework-name filter dropped a project's own `Task` at extraction. Framework names are now recorded and marked `engine` at resolution only when no project type matches. - Owners came from line numbers, so two classes on one line shared members. Owners and full names now come from range containment. - Delegates (`type`) and properties (`variable`) are recorded, as giancarloerra#208 asks. A member-access receiver may end in static members (`Config.Instance.Load()`), so `csMemberReceiver` lets resolution try a shorter prefix of the written path — but only for a type that declares the next segment: a member symbol, a field / constant / event / enum member among its new `csMembers`, or either inherited from a project base. Otherwise the edge stays unresolved, so a namespace segment never binds a same-named class. A file's `using` aliases are written out to the path they name before any edge is recorded. Types record their written bases (`csBases`); a base is looked up as C# looks it up — an exact full name under each enclosing type and namespace, innermost first, then under the file's imported namespaces, an ambiguous import followed by neither — never by name across the project. Qualified calls use it for static methods a type inherits. Members of a base outside the project stay unresolved, and a primary-constructor argument (`X` in `: Base(X)`) is no longer recorded as a type reference.

Follow-up, folded into 4041e70 (the branch is now two commits: d0aac8d for the first round, 4041e70 for the review):
|
A C# path is now answered only by a symbol whose exact full name C# would bind from the caller: its enclosing types and namespaces, innermost first, then what is imported at that line. The suffix fallback is gone, so a path no visible symbol matches stays unresolved instead of binding a same-named type in another namespace. - `global::` anchors are kept on the written path and looked up in the global namespace alone; a file-level alias target is anchored the same way. - `using`s and aliases inside a namespace block apply to that block only. - An extern-alias path (`Legacy::X.Y`) is not resolved. - `this.` and `base.` calls resolve to the caller's own type and its bases; any other receiver (a variable, a call result, `?.`) stays unresolved. - A static call on a .NET framework type is `engine` unless a project type of that name is visible, in which case a missing member stays unresolved. Tests: regressions through extractor and resolver for each case above, each checked red against a mutation of the code it covers.
A base is looked up from its type's enclosing types, whose own bases are looked up in turn, so nested types made the walk exponential in their depth: ten nested classes with four bases each took 20 s to resolve, twelve over two minutes. Each (type, base) lookup is now cached; a lookup still under way answers nothing, which also ends a cyclic hierarchy and replaces the depth counter. Results on a 20,223-file solution are unchanged. The extern-alias regression now pins the exact edges instead of a negative.
The call keeps its written namespace and resolves by it; an unknown lowercase namespace stays unresolved rather than reaching a same-named local method.

All four are addressed at 59943a5. Each case you listed has an extractor → resolver regression, and each one fails when the code it covers is mutated.

… usings to their file A framework type name now counts as .NET's only alone or under `System`. After a variable or a type the same name is a member (`item.Action`, `Settings.Environment`), so such an edge stays unresolved instead of being hidden as `engine`. A tuple element's label (`Total` in `(int Total, Order Item)`) is no longer drawn as a type reference. A `global using` now applies to its own file only. The directory-prefix guess at which files share a compilation is removed: that is a project-system fact the graph does not read.
C# looks a name up namespace by namespace, innermost first: at each level the namespace's own types, then the imports of the block declaring it. The file's imports come only after the global namespace's types. Resolution now walks that order instead of trying every scope before any import, so a namespace block's `using` beats a global-namespace type of the same name. A block's `using` is resolved from the block's namespace outward (`using Billing;` inside `namespace App` names `App.Billing` when the project declares it) unless `global::` anchors it. A file-level one is resolved from the global namespace. An import brings in types, not namespaces, so `X.Y` is taken from one only when `X` is a type it imports. Imports now belong to the exact block that declares them. Each importing block is recorded with its full namespace and its enclosing importing block, and each declaration records the innermost one it sits in. A C# edge's caller is now the innermost declaration containing it by byte offset, not by line. Blocks and classes written on one line therefore no longer share imports or callers.
C# looks a simple name up as a value before a type: first a local or parameter, then a member of each enclosing type, innermost first. A parameter `Report` therefore hides a project type `Report`, and `Report.Print()` is an instance call. The extractor now records such a receiver as `?`, an instance receiver that stays unresolved. This covers a local, a parameter, a pattern or range variable, and a field, property, constant or event of an enclosing type declared in the file. Its member access draws no type reference. The resolver does the same for a member that the caller's type declares in another file or inherits from a project base. A nested type of the same name, declared nearer, still wins. A value whose declared type has its own name (`Status Status`) may be read as either, so it hides nothing and the type lookup decides. Types record these in `csSelfTypedMembers`. A member access is now flagged `csMemberReceiver` whatever its length.

…type identity An alias declared in a namespace block now has its target looked up as C# resolves it. The lookup starts at the block's namespace and goes outward, without the block's own imports. It never starts from where the alias is used, so a nested namespace at the use site can no longer redirect it. The written path keeps the declaring namespace as its anchor (`App.Shop::Billing.Calc`); `global::` stays as written. When that lookup finds nothing, the reference stays unresolved. A value whose declared type ends in its own name is read as the type only when both readings name one type. `csSelfTypedMembers` now keeps the declared type, and resolution compares it with what the name finds from the caller. A qualified type naming another type (`Other.Status Status`) or a nullable value type is still a value. For a local or parameter, only a plain `Status Status` qualifies. A switch expression arm now scopes its pattern variables, so a variable in one arm no longer hides a type in a sibling arm.

This names declarations fromfield("name"), records each one's namespace-qualified full name, adds creation / type / base-list / qualified-member edges that keep the path the source writes, and resolves each written path as C# looks it up from the caller: an exact full name under its enclosing types, then each enclosing namespace, innermost first, with the imports C# consults at that namespace's level.

Aglobal::path is looked up in the global namespace alone; a path through an extern alias is not resolved. Ausingalias is written out with the place it is declared as its anchor (global::for a file-level one,App.Shop::for one in a namespace block), and its target is looked up from there outward, without that block's own imports, never from where it is used; a target not found there stays unresolved.this.andbase.calls resolve to the caller's own type and its bases; a call result or?.names no target and stays unresolved. A receiver that names a value is an instance receiver (receiver: "?"), unresolved, and draws no type reference: a local, parameter, pattern or range variable, or a field / property / constant / event of an enclosing type, as C# looks a simple name up — the extractor sees those declared in the file, the resolver those in another part of the type or inherited from a project base, and a nearer nested type of that name still wins. A value whose declared type ends in its own name (Status Status) hides nothing only when both readings name one type: a member's declared type, looked up where it is declared, must be the type the name finds from the caller (csSelfTypedMembers); a qualified type naming another type, a nullable value type, or one either reading cannot find keeps it a value. A pattern variable is scoped to its block, switch section or switch-expression arm. A creation resolves to the type's declared constructors, or the type itself when it declares none. A member-access receiver falls back to a shorter prefix only for a type that declares the next segment (a member, a field / constant / event / enum member incsMembers, or one inherited from a project base). A static call on a .NET type isengineunless a visible project type of that name shadows it; then a member it lacks stays unresolved.types.ts:SymbolNode.csFullName,csMembers,csSelfTypedMembers,csBases,csUsings,csBlockUsings,csBlock,SymbolEdge.csMemberReceiver, and the C# meaning ofreceiver(this/base/?); graphs persisted without them resolve byqualifiedNameas before.Type of change
