Learning: LesnyRumcajs prefers to rely on BufWriter's Drop implementation for automatic flushing rather than explicit flush() calls in Forest codebase.
⏰ Context from checks skipped due to timeout of 90000ms. You can increase the timeout in your CodeRabbit configuration to a maximum of 15 minutes (900000ms). (9)

45-45: Mainnet checkpoint added — placement matches monthly cadence.

Epoch 5,270,400 is correctly inserted above 5,184,000, preserving descending order and 86,400-epoch spacing.

Please also validate the new CID against tool output:

  • timeout 15s forest-tool archive checkpoints mainnet | head -n1
  • Ensure epoch=5,270,400 and the CID matches line 45.

10-10: Approved: top-of-list cadence verified for calibnet and mainnet

Cadence check passed for both networks; no further changes required.
