Ch. 0191 — Failure-mode resolved: combat mode is on the reverse side of the manual
Ch. 0193 — Failure-mode fully resolves: Tornado Tempo lands the first real hit

Cashes the Ch. 0168 Climate-Baton invention into combat-deployment — and operationalizes the prototype-fails register. The weapon mechanically works (CHAK, POOF, KA-CHAK trigger-grammar) but the payloads are magic-trick gags. Pre-loads the forward-canon Clima-Tact upgrade-arc where the true weather-attack mechanism activates. The according to the instructions, this is a rifle / no I have to trust him line foreshadows that Usopp’s instructions are operationally-correct-but-incomplete; the Nami-learns-to-weather-attack training-arc is forward-canon.
