claudeandClaude Opus 5.5 1a1fb93da8 Phase 4: veins in every chunk, drops for the mobs the island lacks
Ore veins: make_world.py loads the island again row by row until
Regenerating Ore Veins has filled every chunk (/cobblesurvival veins
unfilled), cave tiers sit at their biome's depths, small zones get denser
veins, showcase veins are full size. The world report checks surface
tiers against the zone grid, cave tiers within two biome cells of their
cave, and fails on unfilled chunks; the template passes (37,689 chunks).

Drops: tools/drop_audit.py checks every creature drop a recipe or brewing
needs (docs/pokemon-drops.md). Blaze rods, ghast tears, breeze rods,
shulker shells and nether stars now drop from Pokemon through species
additions (self-test drop_additions_apply). The field guide counts vanilla
mobs as absent, applies species additions and reads the veins as sources.

Cobblebase tried (loads, self-tests pass) and left out until Adrian
decides its scope. Phase 4 checklist with the open questions.

"""Create or update a Prism Launcher instance from build/stage/full.
Writes instance.cfg and mmc-pack.json (Minecraft + NeoForge from pack.toml),
then syncs the client-side files with packwiz-installer. Run tools/build.py
first. Run it again after changing the pack; options and saves in the
instance are left alone. Close the instance in Prism before syncing.
When build/world-template exists (tools/make_world.py), it is copied into the
instance as the save "Cobblemon Survival Island" unless that save already
exists; --replace-world overwrites it, --save-name puts it into another save
folder instead (e.g. next to a save someone has played).
Usage: tools/prism_instance.py [--name NAME] [--prism-dir DIR] [--memory MB] [--replace-world] [--save-name NAME]
