Phase 5: Cobblebase jobs take back gated work, dig only zone ores

From Adrian's Mining test (2026-10-31):

- A gated job assigned to a pastured Pokemon that doesn't pass its gate
  is taken back at once (BaseManager assignment cleared, Cobblebase's
  assignment sync sent, owner told what the Pokemon needs), so it no
  longer sticks or shows under Buffs -> Active.
- Mining, Ore Finder and Evolution-item Finder only give the ores and
  evolution stones of the pasture's zone: new loot condition
  cobblesurvival:in_zone, the pack's versions of the 12 Cobblebase
  tables (tools/cobblebase_loot.py), Cobblebase's built-in copies
  removed at server start (ore/BaseLoot.kt). Mining adds quartz and the
  evolution stones, drops the type gems.
- Mining's loot reaching the chest needs an Item Gatherer in the same
  pasture (Cobblebase's design); documented, not changed.
- Self-tests gated_jobs_are_taken_back, base_jobs_dig_their_zones_ores;
  docs, balance table, licenses, Phase 5 checklist.

+**Cobblebase Mining, from Adrian's play-test (2026-10-31):**

+- *Loot on the ground.* Cobblebase's Mining never fills a chest: it drops what it digs at the Pokémon's feet, tagged with its pasture. A second Pokémon in the same pasture working as **Item Gatherer** (open from the start) picks up items tagged with its pasture and puts them into the best container within 12 blocks of it. Untouched, the loot despawns after 5 minutes like any dropped item. Left as Cobblebase designed it; direct delivery would be a change in the companion mod.
+- *Gated jobs don't stick.* Cobblebase lets the player assign one job per pastured Pokémon in its Skills tab, and the Buffs tab's "Active" list shows the assigned jobs. A job the Pokémon doesn't pass the gate for is now taken back the moment Cobblebase ticks it: the assignment is cleared, every client gets Cobblebase's assignment sync (so it leaves the Active list), and the owner is told what the Pokémon needs (`progress/CobblebaseGate.kt`). The job's button still shows in the Skills tab. Hiding it per Pokémon would need the gate tables sent to clients and a client mixin into Cobblebase's `SkillsPanel` (the screen already knows each pastured Pokémon's level and held item); not built, offered to Adrian.
+- *Ores from the pasture's zone only* (Adrian: only the items of the zone the pasture is in). Mining, the Ore Finder and the Evolution-item Finder roll Cobblebase's tables `mining_*`, `finder_ore_*` and `finder_evo_*`. Cobblebase rolls its own built-in copy of a table (without loot conditions) and only falls back to the data pack's table when it has none, so the companion mod removes its copies of those twelve tables at server start (`ore/BaseLoot.kt`) and the pack ships its own versions (`datapacks/core/data/cobblebase/loot_table/`, written by `tools/cobblebase_loot.py` from Cobblebase's): every ore and evolution stone carries the loot condition `cobblesurvival:in_zone` (`zone/InZoneCondition.kt`) naming the zone of its tier in `world/zones.json`, checked at the Pokémon's position. Mining also gets the zone ores Cobblebase leaves out (quartz, the evolution stones) and loses the type gems, which are crafting shortcuts to gate materials (a Fire Gem makes a Heat Rock); ruins archaeology still has the gems. Cobblestone, gravel, flint, tumblestones and fossils stay everywhere. A table an operator edits in Cobblebase's own loot editor still wins.

 ## Notes for Phase 6 (researched 2026-10-31)
 
 Adrian asked for existing mods for the multiblocks, or at least their logic. Phase 6's machines need a pattern-checked structure with a controller, a Pokémon stored inside (keeping its data, visible), safe return when the structure breaks, and state that survives unload and restart. Power is already Poke Power's (Phase 4), so the first machine is the Large Furnace. Nothing on NeoForge 1.21.1 puts a Pokémon into a multiblock; the structure part has several options:
