* perf(ports): run lsof without blocking on dead network mounts
Without -b, lsof stat()s every mounted file system before answering. A
hard-mounted network share that stops responding blocks that call in the
kernel, so each port scan left an unkillable lsof behind. Pass -b -w to
the lsof queries that name no file (port list, process cwd, executable
path); their output is unchanged. The -U and +D queries keep stat
because -b makes lsof reject named-file arguments.
Linear: STA-9017, STA-9716
* perf(ports): name the stuck lsof helper in the comment; plain readiness test name
* test: query a known child executable in lsof readiness smoke test
* fix: recover from an alternate shell install, and close the relay echo gap
#18768: a startup profile that `exec`s a second install of the same shell keeps
the pid but loses the wrapper's ready marker, and the recovery probe rejected the
replacement's different canonical path -- costing plain Codex the full 15s
barrier. The probe now also accepts an install that the pane's own PATH resolves,
so a binary merely named bash/zsh outside it stays rejected.
#18767: the SSH relay left plain Codex on early startup delivery, displaying the
launch twice under a slow profile. The shell is the host's to know, so the relay
now folds it into the same rule the daemon uses, and the SSH background client
waits for the marker on any Codex launch. Bracketed paste is now gated on an
observed marker rather than on the intent to wait, so a fallback release on a
host shell that never publishes one submits raw.
The non-daemon local provider needs no change: it hands Codex to the wrapper's
own prompt hook and never writes it into the PTY.
* review: correct an overclaiming comment, announce a silent skip, drop a shim
Readiness review of #18796. The delivery comment claimed waiting "costs nothing",
which is only true on a host that arms the marker -- fish, sh, Windows and hosts
predating #18767 release on the fallback instead. Say so.
The alternate-install recovery tests skip on usrmerge hosts, where /usr/bin/bash
resolves back to /bin/bash; announce that rather than reading as coverage that
does not exist.
Import the line-editor predicate from shared directly instead of through a
re-export left on daemon/shell-ready.
