… shape PHP FQCNs, regexes and date formats no longer become PathLiteral nodes. Closes FU-2026-10-22-912dc51dcfc2.
Negative numeric literals now parse too, so [-1] and WHERE x > -3 work. Closes FU-2026-10-22-fcf7c6599d5d.
…the superseded generation Every sweep takes a dry_run flag; a forced index sweeps the repo's stale same-SHA generations while keeping the one it just published. Closes FU-2026-10-22-3277e4242b4e, FU-2026-10-22-d4d7cda5555d.
…quences
An escape splits a double-quoted string into several content children.
PHP kept the last one ("C:\\x\\f.txt" read as f.txt); Ruby and Swift
kept the first (C:), so the path was dropped. Found by the 14-language
backslash tests of FU-2026-10-22-912dc51dcfc2.
…orpus_digest A flow on a 589-file corpus spent ~35 KB of a 38 KB payload on hashes of files it never mentions. corpus_digest is one hash over every file, so the edit hook still sees a change to a file outside the map. Closes FU-2026-10-22-5f880544b34a.
… call
call_user_func('App\\Rows::hero'), [Rows::class, 'hero'], [$this, 'm'] and
Ruby send(:helper) / obj.send(:helper) record the callee an ordinary call
would; an invalid literal keeps its blind spot.
Closes FU-2026-10-22-cae46d5c7b80.
…ions only at Global Laravel's global config() bound a private test method config() at 0.7 (896 edges, 191 from prod). JS/TS/Go stay unchanged: their parsers still write some member calls as a bare name. Refs FU-2026-10-22-dd27e2561be2.
…P self::/static::/parent:: fallbacks are member calls The overlay re-resolver now drops methods from a bare PHP/Python/Rust/C call's Tier-3 candidates, as the index does. A scoped call whose class does not declare the method (a trait method, an unknown parent, $cls::m()) now records an untyped member call instead of a bare name, which the new rule would no longer bind. Closes FU-2026-10-22-dd27e2561be2.
…ites A receiver call never binds a top-level def, so the receiver forms target a class method; bare `helper` without parentheses is no call in Ruby.
…ed as an argument get edges A: a read of a module-level/static constant emits ReadsField reason value_read (same-file 1.0, import 0.95, global-unique 0.7). B: a function passed by name (callback, method reference) emits References reason function_reference from the registering function, never a Calls edge. Parameters and locals shadow. 14-language tests. Closes FU-2026-10-22-211bb553d7e3, FU-2026-10-22-593f351f77cf.
…attr fan-out FastAPI Depends(get_db) now also yields a certain function_reference edge, so it no longer isolates a low-confidence path. Drop an unused import.
…llee's return type
Parsers record Foo.create().bar() as CallSite::ChainedMember{inner, fallback};
the resolver binds bar on create's declared return type through the
receiver ladder, else resolves the old entry. The overlay reads return
types from graph.bin's FunctionMeta; no stored format changed. Generic
returns (Promise<Foo>, Vec<Foo>) keep today's behaviour. 13 languages with
methods, plus a C nested-call test.
Closes FU-2026-10-22-67874c602c84.
…egment; Dart methods carry their return type The JS parser writes a chained fallback as the whole callee text (new Foo().bar). Dart method_declaration nests function_signature under method_signature, so methods had no return type; a written-type-less static method put `static` in the return_type field.
The value-read scan compared each node's kind and each child's field name against up to 30 strings. On vscode that added about 35% to the field-read walk (2.74s vs 2.00s CPU over 8000 files). A per-file table indexed by kind_id and field_id now holds those classes, so the walk compares strings once per distinct kind and field. The walk now costs 2.04s, and the graph is unchanged: same node and edge counts, same sorted dump of the 20,345 value_read and function_reference edges.
…ty; subscript columns name their index collect(x)[0] used to parse into a per-row Subscript that the executor did not group, and the aggregate's eval error became Null on every row. It is a parse error again, naming the WITH ... AS xs RETURN xs[0] form. n['name'] now reads the property as n.name does instead of Null. Two subscripts of one base got the same default column name (xs[]), so ORDER BY sorted by the wrong one; the name now carries the index.
The in-flight guard skipped every dir younger than 10 s except the one just published, so two forced builds within 10 s kept both generations. A lower generation of the published SHA is superseded, not in flight; a build still writing that SHA keeps its .building marker, which skips the whole SHA. The test now publishes twice without ageing the first dir.
…fixes win over metacharacters; PHP interpolation yields no value
An escaped FQCN with a leading backslash ("\\App\\Models\\User") passed the
UNC rule. A drive-prefixed path holding + or $ (Notepad++, c$ admin
shares) was rejected as a regex. A PHP encapsed string with a member,
subscript or braced interpolation copied that code into the value; it
now yields no value, as a plain $var interpolation already did.
…sure is no chain in Go, Python, Swift A JS chained site kept the whole receiver text as its fallback, so a 200-call builder chain stored 72 MB in one file's parse cache. The fallback is now the member name, as in TypeScript; resolve_chain took the last segment anyway. In Go, Python and Swift a chain whose inner callee is a local or parameter closure took a same-named module function's return type; it is now the plain site, as Kotlin and Dart already did.
… and class constants resolve by owner
Name scan (calls.rs + per-language specs):
- a method reference keeps scanning field reads below it (F2)
- PHP $var is never a constant (F3); JS/TS destructuring declares (F4)
- Kotlin named-argument labels, Python global statements (F6, F7)
- Go map-literal keys are expressions (cx7); aliased imports pass the prefilter (cx5)
- C# tuple / LINQ let, Java type / record patterns, Python case captures,
*rest and keyword-pattern labels declare names (F11)
- PHP string callables (array_map('fmt'), usort($x, 'Cls::m')) reference the function (S9)
- Ruby send(:name=) / operator symbols are valid method names (F13)
Resolver (builder.rs resolve_name_ref):
- a bare name reaches a constant its class inherits (HeritageScoped) (cx6)
- Go import names never resolve to a global value (F5)
- a type-owned constant is no bare read outside languages that allow it (R4);
PHP class constants now carry their class as owner
…s type library returns as external - The free-only rule (PHP/Python/Rust/C bare call reaches no method) now holds at the same-file and heritage tiers, not only global (R3); the overlay keeps it across its retry (R5) - A chained call types its receiver with the callee file's imports (Python/TS/JS); other languages bind only a type the callee's directory declares, so a library return type never binds a project namesake (R1) - Python sym.attr.m() is an untyped member call, not a bare call (R2)
…ack target The type-member guard rejected every owned target, and a function declared inside another (TypeScript 'function update' handed to 'r.map(update)') carries the enclosing function as its owner. vscode lost 976 such function_reference edges. The guard now applies only when the owner is not a callable of the target's file.
…ction_reference reasons
Giving PHP class constants their class as owner_class dropped their File -Defines-> edge (scope_defines skips owned nodes) while class_membership linked only Property members, so 428 constants of a Laravel repo had no incoming edge. An owned Const now gets HasProperty from its enclosing class / interface / trait; enum constants stay unowned and keep Defines.
…ructuring targets
- A bare function name in PHP/Python/Rust/C (array_map('fmt', $xs))
names no method at the own-type, inherited, same-file or global tier.
- passed_callable reads a named `callback:` argument, keeps the string's
namespace, and yields nothing where the file declares the builtin's name.
- A JS/TS destructuring assignment (`({ data: current } = res)`) neither
reads nor declares the names it writes; a default value is still read.
- Two types of the owner's name in one file skip the inherited tier.
- A PHP 4 constructor no longer exempts its class's constants from R4.
- Share the string-callable parse between call_user_func and array_map;
stamp PHP const owners only when a const lacks one; fix NameRefSpec docs.
…pick - CallSite::reaches_free_only in ecp-core replaces the index and overlay copies. - lookup_call_in_file filters methods in its iterator instead of collecting decls_in_file for every free-only bare call. - declares_type_beside drops its redundant same-file pre-check. - The overlay converts a callee file's imports once, not per chained call. - Chained-member docs state that a type from another directory binds nothing.

The title names three of the main change areas (constant readers and callback references, chained calls, free-only bare calls, cypher list indexing) and matches the PR objectives. It is long, at 112 characters and 14 words, and packs several features into one line. It is still specific and related to the changeset.

A Dart callee file reaches the fallthrough return-type arms only without imports. It is a part file, whose types come from its library's scope, or a library that sees no other project library. Neither a same-directory file nor a unique project namesake is visible to it, so return Unknown and leave the call to the parser fallback, as main did. This covers URI and named part-of directives without a new import representation. Adds named part-of negatives and a library-type recall control in the index and overlay suites.
…-type edges F5: an include that resolves but does not declare the type now falls back to a same-directory declaration for C++, as a precompiled header or a transitive include reaches a header the graph does not follow. An ambiguous include stays conclusive: imported_file_type reports Unique, Missing or Ambiguous instead of collapsing the last two. F6: rustc rejects a name two globs both supply (E0659), so a local glob hit outranks a direct glob the graph cannot open. Named external imports and external re-exports stay authoritative. R1: assert the Namespace -> Const Defines edge for a braced PHP namespace.
… no name Go: `import _ "x"` and `import . "x"` kept the marker as imported_name, so imports_edges resolved a symbol named `_` (stringer's `func _()`) as the import target. The marker stays in alias only; imported_name is the package path's last segment again. Rust: a bare first-hop `use config::T` beside `mod config;` is anchored as `self::config`, as the nested hop already was (one helper for both). Both hops stop at the first module file that exists, so the overlay no longer probes the parent-directory fallback after a hit and reports a crate-root namesake as ambiguous. Dart: correct the guard comment; sibling parts are in library scope.

- Around line 327-334: Update collect_scope_body to record bindings from
range_clause and receive_statement left sides, and type_switch_statement
aliases, in values so binds_local recognizes them as shadowing import names. Use
record_names for left-side bindings and store the type-switch alias name
directly; add a regression test based on
test_resolve_call_go_local_and_parameter_shadow_import_alias_return_no_edge that
verifies a range variable matching an import alias emits no receiver call edge.
Review comments at @crates/ecp-analyzer/src/javascript/receiver_types.rs:
- Around line 123-127: In `resolve_call`’s receiver-type handling, use
`CallSite::untyped_member(prop_name)` for both the unknown inner-chain fallback
and the `None` `call_expression` case, preventing untyped call members from
resolving through imports, heritage, or free functions. Preserve
`FromReceiver("this", ..)` on the separate `this` path, and add a test
confirming `fetch(u).json()` creates no `Calls` edge to a project-level `json`
function.
Review comments at @crates/ecp-analyzer/src/resolution/resolver.rs:
- Around line 978-981: Update the resolver handling of ImportedFileType::Missing
so repository-owned Dart package: imports are resolved through the project
package mapping instead of being treated as conclusive when unprobed. Preserve
unresolved behavior for external packages and filtered imports; do not change
all skipped imports to Unknown. Add coverage for a chained call through a
project-local package: import.

…project package imports Three regressions against 0.16.2, found in review of PR 861: - Go: names a `:=` range clause, receive case or type switch declares now shadow an import of the same name. An `=` assignment keeps the outer variable and its type; a type-switch alias takes effect after its guard. - JavaScript/TypeScript: a call or `new` receiver whose type stays unknown falls back to UntypedMember, so no import, base class or free function binds `fetch(u).json()`. - Dart: `package:<name>/<path>` resolves to `<root>/lib/<path>` under the importer's nearest ancestor holding that file; otherwise the import stays external.

Summary
ecp impactnow sees bare constant reads and functions passed as values in all 14 mainstream languages, and a member call on a call's result (make().run()) binds through the callee's declared return type. Bare calls in PHP, Python, Rust and C stop binding unrelated same-named methods. Cypher gains list indexing and slicing.Door: two-way.
git revertrestores the old behaviour. The builder fingerprint (+schema20) and the parser fingerprint make every cachedgraph.binrebuild on upgrade and again after a revert; no NodeKind, RelType or rkyv discriminant changes, so no stored data needs a migration.Blast radius (
ecp impact --baseline origin/main, non-test direct callers):PickFacts30,ModuleFacts28,kind_predicate28,TypeFacts19,chained_member18. All sit on the resolution path shared by the index (resolver.rs) and the overlay (session/view.rs); every resolver change below lands in both adapters and is pinned by an overlay parity test.What changed

An independent check attributes the ratio to two changes together (the directory index and the duplicate-import fix), not to the directory index alone; no single-change control build was run.
Calls corpora against 0.16.2 (gin, fd, slim at pinned commits, measured at
8279a9a7), matched by endpoints:Every removed gin edge checked was a name-fallback false edge (
errors.New→gin.New,io.Copy→Context.Copy,http.Dir→gin.Dir,c.Writer.Header().Set→Context.Set); added edges are mostly typed handler-closure calls (c.String,c.JSON). Go parse costs about 21% more per file (new literal-key and scope walks; FU-2026-10-23-09951e9055ed).Review: four source-review rounds, a final opus review and a cross-family codex review of the last delta.
