-- [ ] MinIO running in compose.yaml — integration tests need the local S3 endpoint

+- [x] `backend/internal/files/store_test.go` — compile-time interface assertion (TestStoreImplementsFileStorer), skip-if-no-endpoint live test
+- [x] `backend/internal/files/store_unit_test.go` — pure unit tests: byteCountReader behavior, content-type sniff + body reconstruction
+- [x] `backend/templates/files_helpers_test.go` — pure unit tests: formatBytes boundary cases
+- [x] `backend/internal/web/handlers_files_test.go` — integration stubs for FILE-01..FILE-06 (TestFileUpload, TestFilesList, TestFileDownload, TestFileDelete, TestFileOwnership, TestFilesTab)

 ## Validation Sign-Off
 
-- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
-- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
-- [ ] Wave 0 covers all MISSING references
-- [ ] No watch-mode flags
-- [ ] Feedback latency < 60s
-- [ ] `nyquist_compliant: true` set in frontmatter
