- Extract shared utils: asSafeChunkSize (validation.ts), S3 detection (s3-detection.ts) - Remove dead _handleMaybeS3Root from index.ts and routes/index.ts - Remove dead _asArray from file-controller.ts - Consolidate maybeCompressChunk into shared compress.ts - Extract checkConditionalHeaders helper, remove ~120 lines dupe in s3-controller - Remove 500+ lines dead code from s3-object.ts (unused use cases + helpers) - Delegate upload-file.ts chunked path to ChunkedStorage, remove dupe - Fix broken dynamic import in file-controller.ts → proper DI - Fix test/files.test.ts import path and mocks [skip ci]
