- wire row: a client close on a served pipe row fires the per-channel
cancel (kill-on-drop witnessed before teardown, no exit report
fabricated, ended lifecycle event) and releases the cap (over-cap
open refused at 1, re-open admits + routes after the close)
- wire row: the Closed no-exit-chunk close shape, constructed through
the real path (an oversized shim chunk dies at alktty's own
ChunkWriter validation -> bridge EOF, scripted exit never forwarded,
plain close, nothing fabricated); Break's frame classification
pinned by a unit row (wire-unreachable through the validated writer
at this pin - recorded)
- module docs: the stdout write_all no-deadline known limit recorded
(the gate's disposition: bounded backpressure, inactivity-timeout
liveness; a deadline would be a behavior change)
Verification: cargo test (default/session/session+git/git/tunnel/sftp/
--all-features, tty rows 5x repeat), clippy x2 -D warnings, fmt, doc,
taskgraph validate
