Filer-level tests (filechunk_manifest_test.go): - TestManifestRoundTripPreservesChunks: create -> serialize -> deserialize preserves fileId, offset, size, and timestamp for all sub-chunks - TestCompactResolvedOverlappingManifests: two manifests covering the same range, older sub-chunks correctly identified as garbage after compaction - TestDoMinusChunksWithResolvedManifests: old manifest sub-chunks detected as garbage when compared against new clean chunks (mirrors filer cleanup) - TestManifestizeSmallBatchWithRemainder: batch=3 with 7 chunks produces 2 manifests + 1 remainder, all data recoverable after resolve - TestCompactMultipleOverlappingManifestGenerations: 5 generations of full-file manifests, compaction keeps only the newest generation - TestManifestBloatDetection: with N overlapping manifests, merge triggers at N >= 2 (stored > 2x file size) Mount-level test (weedfs_file_sync_test.go): - TestFlushCycleManifestAccumulation: simulates the flushMetadataToFiler pipeline over multiple cycles with a small manifest batch (5 chunks). Verifies merge triggers at cycle 2 when accumulated manifests exceed the 2x threshold. Uses SeparateManifestChunks + CompactFileChunks + shouldMergeChunks to mirror the real code path.
