Adrian (2026-10-31): add Cobbreeding without a gate; only Ditto should
be rare, in an endgame area or gated behind something else.
- Cobbreeding 2.4.1 (Modrinth only) and Cloth Config (client) in the
pack; Cobblebase's hatchery takes Cobbreeding's eggs.
- Ditto moved from Button Isle to the Deep Dark with both of Cobblemon's
entries (rare in slime chunks, ultra-rare elsewhere): zone_spawns.py
pins take {"zone", "all_entries"}; Deep Dark target +1, Button Isle -1
so no other line moved; Southwold and Frostpeak guardians pinned (they
tie on base stats and flipped between runs).
- HMs' Trainer Ditto is made uncatchable; it still trades.
- check_deps.py skips other-side dependencies; Cobbreeding's harmless
client-mixin log line allowlisted.
- Self-tests cobbreeding_eggs_fit_the_hatchery, trainer_ditto_cant_be_caught;
docs, balance table, Phase 5 checklist.
