`check` walks the base graph's call sites to find callers of a removed or renamed symbol, so each dangling caller kept its base line: deleting a function above its caller reported the call past the end of the file or at another function's line, while the same report's `signature_changes` used working-tree lines. MCP write tools and the `no_dangling` contract repeat the same keys. For a caller the check re-parsed, the site moves with the caller: when the edit left the caller's body alone (same fingerprint and length) its call moved by the caller's own line shift, exactly; when the body changed, the base line is kept and marked `line_from: "base"`. Callers in untouched files are unchanged, since their lines did not move.

Check name Status Explanation Description check The description includes the required summary, demo, change type, issue link, test plan, and checklist. It documents the implemented behavior and test results clearly. Linked Issues check The description links issue #3171with Fixes syntax, and the implementation directly addresses that issue's requested dangling-caller reporting behavior.Out of Scope Changes check The changes remain within scope. They update dangling-caller line handling, contract formatting, constants, and related tests. Title check The title clearly identifies the dangling-caller reporting fix and matches the primary change in the pull request. Out of Scope Changes check The production changes adjust dangling-caller locations and expose the base-line marker. The contract and tests support issue #3171. No unrelated change is demonstrated.

Explanation
Issue
#3171requires working-tree locations for re-parsed dangling callers, aline_from: "base"marker when the line cannot be moved safely, unchanged locations for untouched files, and deletion and rename regression tests. The implementation shifts unchanged callers, marks changed or unverifiable callers, preserves untouched callers, and adds deletion coverage. The reviewed tests do not include the required rename scenario with lines removed above a re-parsed caller.Resolution
Add an automated rename regression test for a caller in the edited file. Remove lines above the caller, retain the old call, and assert the working-tree line and
renamed_tovalue.

failure details include the dangling caller’s line_from value when present,
preserving the existing path:line format for other findings.
- Around line 714-720: Update the dangling-line mapping branch in the code
around the shown fingerprint-and-span comparison: do not treat matching AST
fingerprints and spans as proof that the call position is stable. Compare the
call’s position in the re-parsed source before applying the caller start-line
delta; if it cannot be mapped, keep the base line and set line_from to "base".

The skeleton drops comments and keeps a string literal whole, so a `# helper()` comment (or a string line) that traded lines with the call left the caller's fingerprint and span equal, and the text check read the callee's name there: the comment's line was reported as the call's working-tree line, without `line_from`. The shifted line is now taken only when the working tree's syntax tree puts that position outside a comment's or a string's text; otherwise the base line stays, marked.

After `from util import helper as h` the call reads `h()`, so checking the shifted line for the definition's name kept the base line; the names the caller's file imports the target as are accepted too.

The skeleton drops names, so with the target imported as `a` and `b` an `a()` could trade lines with a `b()` that a parameter shadows and the shifted line still read as the call; likewise a shadowed `helper()` next to an aliased `h()`. The shifted line is now read for the one name the caller's file spells the target by (its import alias, else its own name) and, when the file imports it under two names, keeps the base line.

Summary
cgr checkreported each dangling caller at the line the call had before the edit. Deleting a function usually removes lines above its callers, so:app.py:10for a 6-line file in the issue);brace()reported atsrc/lib.rs:20, the line ofuses_point'stoo_fewsite).signature_changesuse working-tree lines, the MCP write tools append this delta to every result, and theno_danglingcontract formats the samepath:linekeys. An agent or CI annotation that jumps there edits the wrong place._danglingwalksbefore.sites, the base graph's call sites, and emits theirline/col. The re-parsed caller's new position is never used, because the call no longer resolves and so has no site inafter.sites._move_to_working_tree, for a caller the check re-parsed (the issue's suggested steps 2 and 3):start_lineshift. This is exact, and is the common case of a deletion above.line_from: "base". A newNotRequiredkey, present only then.Demo
