+- **C# reference extraction now suppresses common qualified member-call overmatches (#3894)** — `Path.Combine`, `Math.Max`, `string.Join`, `JsonElement.GetString`, and similar receiver-qualified common calls no longer appear as references to unrelated same-name local functions, while direct and `this.` local calls remain indexed.

+- **C# 参照抽出で一般的な qualified member call の過剰一致を抑制しました (#3894)** — `Path.Combine`、`Math.Max`、`string.Join`、`JsonElement.GetString` などの receiver 付き共通呼び出しが、同名の無関係なローカル関数への参照として扱われなくなりました。一方で direct call と `this.` 経由のローカル呼び出しは引き続き index されます。

+- **C# symbol range regression coverage now locks small method spans (#3912)** — regression tests cover C# methods near local functions, lambdas, generic helpers, and later partial-class members so `definition`, `goto`, `symbols --sort size`, and `outline` keep using tight method end lines instead of class-level EOF ranges.
+
+## 日本語

+- **小さな C# method の symbol range を固定する回帰テストを追加しました (#3912)** — local function、lambda、generic helper、後続の partial class member の近くにある C# method をカバーし、`definition`、`goto`、`symbols --sort size`、`outline` が class 末尾まで伸びた range ではなく正しい method 終端を使い続けるようにしました。

+- **`inspect --path --line` now returns exact or enclosing symbols (#3915)** — file-line inspect resolves a symbol on the requested definition line first, then the smallest enclosing symbol for body lines, so JSON results include `definitions`, `nearby_symbols`, and body-capable symbol context instead of only a source excerpt.

+## 日本語

+- **`inspect --path --line` が exact または enclosing symbol を返すようになりました (#3915)** — file-line inspect は指定行が定義行ならその symbol を優先し、body 行では最小の enclosing symbol を解決するため、JSON 結果が source excerpt だけでなく `definitions`、`nearby_symbols`、body 取得可能な symbol context を含むようになりました。
