+## [Unreleased]
+
+### Bug Fixes
+
+* **hook:** respect Claude Code deny/ask permission rules on rewrite — hook now checks settings.json before rewriting commands, preventing bypass of user-configured deny/ask permissions
+* **git:** replace symbol prefixes (`* branch`, `+ Staged:`, `~ Modified:`, `? Untracked:`) with plain lowercase labels (`branch:`, `staged:`, `modified:`, `untracked:`) in git status output
+
+### Features
+
+* **gradle**: add Gradle command support with sub-enum routing (test/build/other) — 75-90% token savings
+* **maven**: add Maven command support with Surefire test parser (test/compile/package/other) — 70-90% token savings
+* **gradle**: auto-detect ./gradlew wrapper with fallback to gradle on PATH
+* **maven**: intelligent Surefire output parsing — failures only with compact error messages
+* **discover**: add Gradle/Maven rewrite rules for transparent hook integration
