Summary

  • pack_format 15 → 71 to target Minecraft 1.21.5
  • Fix broken tropical_aquarist advancement (1.20.5 breaking change): replaced "nbt": "{BucketVariantTag:...}" item predicates with "predicates": {"minecraft:bucket_entity_data": {"Variant": ...}} in all 22 fish criteria
  • Fix broken enchantment-based advancements (1.21 breaking change): added minecraft: namespace prefix to all enchantment IDs across 12 files; renamed sweepingsweeping_edge
  • New enchantments (1.21 mace): added wind_burst, breach, density to all_enchantments
  • New biomes: cherry_grove, pale_garden in biomes_explore_all
  • New wood types: cherry_wood, cherry_log, bamboo_block in item tags
  • New building blocks (1.20–1.21.4): 6 new stair, slab, and wall types (cherry, bamboo, tuff variants, resin brick)
  • 8 new advancements: armadillo scute, wolf armor, mace, breeze kill, bogged kill, crafter, copper bulb, trial key
  • Cosmetic icon fix: 8 advancement icons updated from legacy nbt to components format

Test plan

  • Install yajsv and run CI validation locally per CLAUDE.md
  • Load pack in a 1.21.5 world and verify tropical_aquarist triggers when catching tropical fish variants
  • Verify enchantment-based advancements fire (e.g. all_enchantments, perfect_sword)
  • Visit cherry_grove and pale_garden biomes to confirm biomes_explore_all progresses
  • Confirm new advancements appear in the advancement tree and trigger correctly

- actions/checkout v3 → v4
- actions/setup-go v4 → v5, Go 1.20 → 1.22
- actions/cache v3 → v4
- actions/setup-python v4 → v5, Python 3.10 → 3.12
- Schema cache key now rotates weekly (date +%Y-%U) so schemas
  auto-refresh rather than being stale indefinitely
- Schema fetch is now conditional on cache miss (was always running,
  making the cache pointless)
- curl uses -fsSL so fetch failures are caught rather than silently
  producing empty schema files

The schemastore minecraft-tag.json schema now requires resource
locations to match '^[a-z0-9_.-]+:[a-z0-9_.-]+', rejecting bare
names like 'oak_log' or '#frog_food'. Fix all 63 failing tag files
by adding the minecraft: namespace to every unqualified value and
#unqualified tag reference.
