live outbound and inbound 通道 directional views

# =============================================================================
# 发送 — live outbound and inbound 通道 directional views.
# =============================================================================
#
# What this teaches:
#   • Directional 通道 views — `发送<T>` for outbound frames, `接收<T>` for
#     inbound frames on a 通道 connection
#   • Cursor iteration — `遍历 取自 t.cursor()` consumes inbound frames
#   • Accipe reception — `accipe()` pulls a single 帧 from the inbound
#     队列
#
# Common mistakes:
#   • confusing `发送` (outbound) and `接收` (inbound) 通道 directional views, or mixing accipe/cursor/exhauri without intentional ordered consumption
#
# See also: 调用, 通道, 接收, 帧, 迭代器, accipe
# =============================================================================

# Live `发送<T>` / `接收<T>` directional views
#
# runtime:echo returns one inbound 文本 frame per conversation.
# accipe, 迭代器, and exhauri may share one 接收 队列; mix them only when
# ordered consumption is intentional.
