Chronicle World Replacement

The complete fail-closed checklist that must pass before Aterra's outgoing world can be replaced.

Last updated Jul 18, 2026 by Chronicle Wiki Importer

Chronicle World Replacement 🚦🌍

Replacing Aterra is the most sensitive part of the Chronicle lifecycle. The system therefore uses a fail-closed readiness gate. Every required condition must pass before the live world can be changed.

Required gates

World replacement is permitted only when all of the following are true:

  • the outgoing Chronicle legitimately finalized
  • The Last Bell was delivered and acknowledged
  • the configured Final Stand elapsed, with an absolute minimum of eight hours
  • a staged .mcworld package exists
  • the staged package passed validation
  • an authorized administrator explicitly approved the package
  • the stored file still matches its approved SHA-256 checksum
  • no replacement for that Chronicle already completed

One red light means the cart stays parked. 🛑🛒

Fail-closed behavior

When any condition fails, the system must not:

  • stop BDS
  • move or replace world directories
  • change PvP settings
  • activate the next Chronicle
  • invoke a world-operation relay
  • mark replacement complete

The current world remains online, and the administration page explains every blocking reason individually.

Expected replacement sequence

Once all gates pass and a separately authorized production operation begins, the expected sequence is:

  1. announce the maintenance boundary
  2. save the outgoing world
  3. create and verify a recoverable final backup
  4. stop BDS cleanly
  5. install the exact approved staged package
  6. verify the installed checksum and world structure
  7. start BDS
  8. verify server health and player connectivity
  9. activate the new Chronicle through the authorized lifecycle path
  10. retain durable completion and rollback evidence

Packaging proof is not gameplay proof. A successful file operation does not prove spawn, menus, behavior packs, Realm behavior, death behavior, or actual play. Minecraft always gets the final word. ⛏️
