It updates stored locations and missing status from scan results and loaded-entity events. The husbandry roster displays missing animals and their last recorded locations when available.

Merge Risk: ⚪ Minimal · up to The previously identified scanner failures appear addressed. The change is mergeable after normal checks. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to An incomplete or invalid saved-entity file can be treated as fully scanned, causing an owned animal to appear Missing when its location has not been reliably checked. The scan does not appear to expand who can view an animal’s roster, but this failure mode weakens the new tracking behavior. Retained concerns

incomplete result when the region data is shorter than the two-sector header, so
truncated files cannot cause absent targets to be reported as missing.
In @src/main/java/net/tfminecraft/cooking/husbandry/HusbandryLocator.java:
- Around line 94-98: Update the scan completion flow in HusbandryLocator to pass
the captured worlds list into apply, and update apply to mark an animal Missing
only when the scan is complete and its non-null stored world matches a world in
that captured list. Do not use the current Bukkit world registry for this
decision.

- Around line 183-187: In the UUID INT_ARRAY parsing path in
HusbandryEntityScan, validate the declared size is nonnegative and no greater
than the remaining bytes divided by four before allocating parts. Treat an
invalid size as unreadable chunk data so the scan result remains incomplete.
- Around line 43-50: Update the world scan loop in HusbandryEntityScan so a null
result from listFiles() marks the scan incomplete when the entity directory
already exists, while preserving the current behavior for a missing directory.
Use the existing complete state and avoid treating an unreadable directory as an
empty successful scan.
- Around line 110-125: Bound decompressed data in the chunk-reading method of
HusbandryEntityScan before it is fully materialized. Replace the unbounded
readAllBytes call on the decompression InputStream with a bounded read, and
reject chunks exceeding a fixed maximum size with an IOException; retain the
existing stream cleanup.

Line 114 uses
intarithmetic. If a region record has a valid offset andlength == Integer.MAX_VALUE,offset + 4 + lengthoverflows, so the bounds check passes. Line 117 then attempts a nearly 2 GiB allocation.scanRegiondoes not catchOutOfMemoryError, so a corrupt region can terminate the scan.
