open_jobs reports a live pending record nobody signals on as `injected`: its producer registered and injected it without a waiter (create --onboard, a job sent by hand), so it holds the session like a running or admitted job, and a waiter of the same second with a lower job id, or one registered a moment earlier and still in its preflight, no longer passes it in the FIFO. The waiter signals on its own record before its first scan, so its record is never mistaken for one. lib_py.pane_lock resolves the shim's ambient target (no -L, HERDR_SESSION_NAME empty or `default`) to the server of the pane the caller runs in - HERDR_SESSION, else HERDR_SOCKET_PATH's layout, as lib.sh _herdr_caller_server reads them - so an ambient and a named call into one server claim under one lock; outside a pane it stays the default server's. Tests: u2h (the tie, the later-registered onboarding, the signalled control), u1/u4 labels, c10 forces the same-second registration, p1b, s2 (real herdr: held lock stops both call forms; mixed concurrent calls take distinct panes). Two FIFO fixtures now carry a waiter's signal. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

"""Issue #50, against a real herdr 0.9.3 server: the registry decides whether a
|
||
session is free (C), and three `create --onboard` at once do not contend (A).
|
||
|
||
Each test gets a one-off herdr server (a session named t50-<uuid>) under a
|
||
short mkdtemp HOME - herdr's sockets, logs and server config live there, the
|
||
user's herdr config is never touched, and a scratch HOME under tmp_path would
|
||
exceed the unix socket path limit. The pane runs a fake claude (a claude-like
|
||
welcome, then it echoes its input), which herdr 0.9.3 reports as `idle`; the
|
||
fake never shows `working`, so `agent prompt --wait` times out and the
|
||
injection is judged by the job's own `started` (Issue #18), which these tests
|
||
publish as the agent would, through the real publish_event.py and the suite's
|
||
local broker. The box is torn down after every test.
|
||
|
||
Measured on 2026-10-10 (job 51ccd800, herdr 0.9.3, a real claude): herdr
|
||
reported `working` only while a job ran and `idle` ~10 s after `completed`,
|
||
background subagent (`← 1 agent`) or not, and a second job was dispatched;
|
||
so the herdr idle wait stays and the registry wait runs before it.
