Reframes the conventional question. Discharges naturally follow the E
field gradient; branching arises from specific randomizing mechanisms
(low frequency cooling reset, simultaneous multi-channel inception,
inter-pulse memory erasure, stochastic perturbations). QCW eliminates
the randomizers, revealing the default straight-line behavior.

Three mechanisms explain sword spark straightness: axial field
concentration at the leader tip, directional thermal pre-conditioning
of gas ahead, and cold-air confinement restricting lateral breakout.
Connects to the "too long ramp" regime where forward bias disappears
and branching returns. Prompted by external reviewer question.

Catalogs what is known (radial expansion, buoyancy, electron/ion drift,
ion wind) vs unknown (net axial flow under AC drive, tip gas dynamics,
acoustic signatures). Prompted by external reviewer question.

Steve Conner's "short bursts outperform long bursts" finding was
presented adjacent to QCW's lower epsilon without clarifying these
are different comparisons. Now explicitly scoped: peak power advantage
is within-mode (burst vs burst, threshold effect), while QCW's lower
epsilon is cross-mode (leader vs streamer plasma type).
