● Here are the results:

---

Phase 1: Truly Unused Code (UnusedDeclaration / UnusedSymbol)

Only 7 warnings in one file:

src/main/kotlin/.../mcp/McpToolSetting.kt

• Two constructors never used
• setToolId, getToolName, setToolName, getDescription, setDescription — all unused

---

Phase 2: Methods Only Used in Tests (93 found)

Checked 4,747 methods/functions across 801 files. Notable findings:

High-value candidates to review (many test refs = well-tested but dead in production):

┌───────────────────────────────────────────────┬───────────┐
│ Method │ Test refs │
├───────────────────────────────────────────────┼───────────┤
│ DoctrineMetadataModel#getField │ 107 │
├───────────────────────────────────────────────┼───────────┤

Parsers only called from tests (likely should be internal/test helpers):

• ConsoleCommandServiceParser#parser, DomainMappings#parser, EntityNamesServiceParser#parser, TwigPathServiceParser#parser, XmlTagParser#parser, etc.

Interface implementations called only from tests (the interface contract may prevent deletion):

• TwigBlockSymbolContributor#processElementsWithName/processNames
• TemplateReference#bindToElement/handleElementRename
• AddServiceXmlArgumentLocalQuickFix#startInWriteAction

Kotlin-only:

• SymfonyConsoleRunAnythingProvider#getMainListItem/getValues
• SymfonyEndpointProvider (5 methods)
• SymfonyShellCommandSpecsProvider#getCommandSpecs

Note: Some of these are interface/extension point implementations that IntelliJ calls via reflection — those shouldn't be deleted even if no direct code references them. Focus cleanup on parser helpers and utility methods first.
