The JSON mirror fast path avoided file replacement but still dirtied directory metadata on every save through chmod. Check the current permissions before repairing them, retaining correction of unsafe modes. A Linux regression reproduces the ctime change and verifies unchanged metadata and permission repair. This is a narrow contributor to #1966, not a claim that aggregate write amplification is resolved.
