The Rust LSP types `root: &Path` and dispatches `root.join(..)` to std.path.Path.join, a registered seed method with no graph node. Both call resolvers treated "LSP row without a gbuf target" like "no LSP row" and fell back to the textual registry, which bound the call to the only project method named `join` (EvidenceTier::join via unique_name). Every std/seeded-crate call whose leaf name a project method shares was fabricated this way. cbm_pipeline_rust_external_target() (lsp_resolve.h) recognises a Rust row whose strategy emits a registered target (method/trait/deref/bound dispatch, direct, ufcs, constructor) and whose QN lies outside the project prefix. Project defs are registered under project-prefixed QNs, so such a target is a std/core/alloc or seeded-crate symbol by construction. pass_calls.c and pass_parallel.c skip the registry fallback for those rows (in lockstep), and the parallel route-method fallback no longer turns a skipped `map.get(k)` into a source->source self-call. Project-prefixed rows, unknown-receiver rows and every other language are unchanged. The call-expression receiver (`root.to_path_buf().join(..)`) needed type facts: Path::join/to_path_buf/with_extension/with_file_name now return PathBuf, PathBuf::as_path returns Path, and PathBuf derefs to Path. Measured on BurntSushi/ripgrep @ 3fce3b5 (fresh index, two runs each, byte-identical): CALLS 5371 -> 5014; 357 removed (307 suffix_match, 45 unique_name, 5 field_type_hint), 0 added, no lsp_* edge touched. Removed samples are all std receivers (String::new -> State.new, msg.contains -> ByteSet.contains, alts.push on a Vec -> TSeq.push). Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>
