Borrowed-Blade Three-Sword Style

The seed-chain

The chapter installs borrowed-blade-three-sword-style as a temporary register with three operational properties:

Discipline is not blade-specific — the three-sword-style can be operationalized with any three katana-class swords. The discipline is philosophy-not-stance (cf. Ch. 33 articulation).
Wado Ichimonji is held in reserve — the Kuina-blade is still with Nami; the chapter does not test the Wado-specifically dimension. The forward-tell: when Zoro recovers Wado, the borrowed-blade register ends and the own-blade register restarts.
The swords-as-interface-vulnerability axiom operates in reverse — the vulnerability of the discipline (can be disarmed) is matched by its strength (can be re-armed by borrowing). The two are the same property.

Recovery of Zoro’s own three blades in the Arlong arc — the borrowed-blade register ends; the own-blade register restarts.
Recurring blade-confiscation beats — Mr. 1, Tashigi, Enma — every later sword-theft / sword-acquisition beat keys to this Ch. 84 register-canonization.
Late-series Wado-specific combat-feats — when Wado Ichimonji is wielded specifically (vs. just any-three-katana), the Wado-as-irreplaceable register operates as the inverse of the Ch. 84 any-three-katana-is-fine register.
