The source Gen2 battle model lacks its public round clock, and native battler data construction is coupled to picture/animation allocation. Expose the existing native counter (initially zero) and extract data construction into Battler.new; BattleState.makeBattler hydrates that same table through the existing sprite and animation factories. There is no second round counter, RNG stream, turn simulator, copied party Pokemon or replacement artwork.

This is a stacked draft on the separately offered model/RNG/friendship work (#395, #394 and their listed prerequisites). Party/move/stat/registry identities, badges, sleep, form-personal records and the older host's existing Gen2 bindings/poison defaults are retained. It does not depend on the newer fork-only HeldItemRead module.

Validation:

• Actual older offered-host extraction source281e5185:577/577 fresh plain-Lua checks without LOVE and with presentation modules rejected;810/810 actual wild-constructor and switch checks over the host's15 advertised editions, invoking the real sprite and animation factories.
• Previous offered-host clock source3e85ef0b:400/400 clock,7951/7951 RNG,210/210 actual native link participant/spectator and262/262 model checks pass independently. Its queue test executes real planner-owned closures in the older host's native insertion context; it does not invent the newer runQueueAction helper. That checkout lacks the newer semantic-checkpoint prerequisite, so the fork-only checkpoint test is not copied here.
• Development-fork extraction source8025abc7:691/691 no-LOVE and972/972 actual native-construction checks over18 editions; an independent original-versus-extracted native constructor comparison matches all270 data/identity/art-selection cases. Separate fork clock negative probe failed295 of400 before the reader; clock400,link210,checkpoint57 and RNG7951 pass after it.

The latest offered head67a05ea1 adds documentation to the tested extraction. Complete current combined-host/regression/GPU qualification remains pending; the previous complete older-host baseline had11 unrelated existing failures. This draft does not claim upstream CI is green, full source Battle.new/standalone turn execution, arbitrary writable model fields, complete unchanged-VASC presentation or release acceptance. No mod changes and no upstream merge is performed.
