A single millisecond delay in reciprocating a bow can register internally as a breach of tacit agreement, even when verbally affirmed.

回礼鞠躬哪怕延迟一毫秒，也会在内心被感知为对默示协议的违背，即便口头已明确确认。
This formality persists because it efficiently resolves ambiguity in high-stakes contexts where verbal clarification would cost cognitive bandwidth.
