Summary

  • After the startup entity scan, an owned animal that is not in any saved chunk of a fully scanned world is deleted instead of left as Missing on /animals.
  • Each drop is logged with the animal name, type, uuid, owners, and last seen coordinates. An incomplete scan, or a last world that was not scanned, keeps the row. A failed delete still marks the animal Missing.

Test plan

  • HusbandryLocatorTest covers the ghost rule and that a drop removes the animal, both owners, and the loaded cache
  • CI development build on the pull request succeeds
  • After deploy, a ghost row is removed at startup and the console logs Dropped ghost animal

Made with Cursor

Summary by CodeRabbit

  • Bug Fixes
    • Confirmed animal records that are no longer present are now removed after a complete scan, along with their associated owner information.
    • Records are left unchanged when a scan is incomplete or does not cover the animal’s stored world. Animals without a stored world can be confirmed after a complete scan.
    • Failed deletions are reported rather than counted as successful, and removed animals are cleared from tracking state.

An owned animal that the startup chunk scan cannot find is only a leftover record. Remove that row and log who owned it, and leave the record when the scan is incomplete.

📝 Walkthrough

Walkthrough

The locator now deletes absent animals when a complete scan confirms their stored world was scanned, or when their stored world is null or blank. It removes animal and owner records, clears cached and missing state, and reports successful drops and deletion failures.

Ghost animal cleanup

Layer / File(s) Summary
Ghost confirmation and scan handling
src/main/java/net/tfminecraft/cooking/husbandry/HusbandryLocator.java, src/test/java/net/tfminecraft/cooking/husbandry/HusbandryLocatorTest.java
The locator confirms absent animals only after a complete scan and when the stored world was scanned, or the stored world is null or blank. It skips unconfirmed animals. Tests cover the confirmation conditions.
Record deletion and logging
src/main/java/net/tfminecraft/cooking/husbandry/HusbandryLocator.java, src/test/java/net/tfminecraft/cooking/husbandry/HusbandryLocatorTest.java
The locator deletes confirmed animal and owner records, evicts the animal from the entity cache, removes its missing marker, and formats a log line with sorted owner details. Scan summaries report dropped ghosts and failed deletions. Tests verify deletion effects and log content.

A ghostly record, then, is gone
Its owners leave the ledger too
The cache is cleared; the count is new
Sorted names shine in the log

Add a second animal owned by the same player.

This is material coverage for deleteGhost. The current fixture cannot detect a deletion that removes another animal or its owner row for ownerId.
