- Add resharding load simulation model with real router hash functions
- Benchmark confirms storage amplification is exactly 2.0× and dual-write
amplification is exactly 2.0× across all test matrix scenarios (1KB/10GB,
10KB/100GB, 1MB/1TB), with hash distribution CV < 5% in all cases
- CLI window guard: resharding.allowed_windows config restricts resharding
to named time windows (e.g. "02:00-06:00 UTC"), CLI refuses outside
windows without --force
- Integration tests confirm rejection outside window, --force override,
no-restriction mode, and disabled config handling
