Two defects in the started-based verdict, both found by the full suite.
The first was destructive. No `started` within T exited 1, which fired the
rollback trap and killed the session. That is worse than the bug being fixed:
create_session already has a rule for "the agent is not responding but the
process is alive" one step earlier - a TUI that never signalled ready is
preserved for diagnosis - and an onboarding that is merely slow is the same
situation. The job is marked `error` and warned about loudly; the session, its
row and the pane stay. MULTI_AGENT_RULES §6 has the GM gate on this job
anyway, so an unacknowledged onboarding still blocks real work.
It also broke 21 tests across 8 modules (create/sanity/tier2/tier3/tier4/
issue15/issue19/issue21) and added roughly an hour to the suite: no sandbox
has an agent to publish `started`, so every create_session test sat out the
full 180 s and then failed on the rollback. MAM_ONBOARD_ACK_S shortens that
wait, and the sandbox fixture sets 3 s. It is deliberately not the wrapper's
MAM_INJECT_ACK_GRACE_S - that is a different wait whose own tests assert on
the value they pass, and reusing it made issue18's acceptance2 read "within
3s" instead of "within 4s".
The second: the delivery failure published `error` and then the rollback
published `cancelled` on the same job, which the registry refuses
("conflicting cancelled after terminal error"). Terminal events are published
exactly once, so the trap now skips a job this run already closed.

Plan commits 3 and 4 landed together: both rewrite the same region of
create_session.sh and share one test file, and splitting them afterwards would
have meant hunk-level surgery on already-verified code.
Delivery verdict (item 3). create_session --onboard called a healthy agent a
failure three seconds after registering the job: inject_instructions ->
send_keys_safe returns rc 4 when `agent prompt --wait --until working` fails
and the pane is still not working two seconds later, which is exactly where a
TUI that is still starting up lands. It never got the ISSUE-18 confirmation the
delegate-job wrapper has. rc 4 is a warning now and the agent's own `started`
decides, within the job's own ack timeout; rc 1/2/3 stay hard failures, since
they say the pane never quiesced, a dialog was blocking, or the text never
appeared, and no later `started` repairs those.
The self-published `started` had to go first. create_session published it on
the agent's behalf right after injection, so the registry showed a started job
whether or not the agent ever saw the prompt - with that line in place, no
started-based verdict can mean anything.
delegate_wait_started is lib.sh's counterpart to the wrapper's _wait_started
(plan item D10-b). The wrapper's own `submit` was the first choice, but it
blocks until the job reaches a terminal state, and create_session must return
as soon as delivery is confirmed; the on-disk evidence it reads - registry
status past `pending`, or a started line carrying this dispatch token - is
written by publish_event before its wire publish, so no broker is involved.
Rollback integrity (item 4). The trap ran `_herdr kill-session -t
"$SESSION_NAME" 2>/dev/null || true`, so a kill that closed nothing still
printed "rolling back" while the session kept running, and the row stayed
`running` pointing at the job the same rollback had just failed (#23 symptom
5). With item 1 in place this check is finally trustworthy: the kill used to
fail because the caller's workspace id hid the pane.
The trap now reads the kill's rc, confirms with has-session, closes the
onboarding job as `cancelled` (a terminal transition the registry knows, and
the truthful one - the job was never dispatched), and marks the row. A session
still alive exits 43 with the manual cleanup command, distinct from 42 (TUI
never ready).
The row keeps a schema-valid status rather than the plan's `error`, which
atomic_yaml.py rejects: `terminated` once the session is really gone, and
`running` when the kill failed, because it is still running. What makes that
case legible is the note, the cleared delegate_job_id and exit 43 - not a
status claiming the opposite of the truth. The row is never deleted; a deleted
row takes the evidence with it.

handle_startup_dialogs was a claude-only string ladder called only when
AGENT=claude, and wait_for_tui_ready does not treat a dialog screen as ready.
So agy, grok and codex sat on their directory-trust prompt for the full
readiness timeout, the session was recorded as tui-ready-timeout, and
onboarding injection was disabled (create_session.sh:313-314) - a human had to
accept each dialog by hand.
The signatures and accept keys move to the adapters as `startup_dialogs`
(pattern, keys, kind), published through the existing `facts` eval contract as
MAM_STARTUP_DIALOGS. claude's ladder moves over verbatim; agy takes Enter, grok
y, codex Enter, and codex's update notice takes 2 (Skip), which blocks a start
just as hard while changing nothing. kind is `trust` or `notice`:
--no-auto-trust leaves trust dialogs to a human and still answers notices,
since trusting a directory makes codex load its project-local config, hooks and
exec policy.
Re-sending is gated by time (MAM_DIALOG_RESEND_S, default 5s), not by frames.
#24's comment reports that `--source visible` keeps showing an accepted dialog
for a while, and _pane_capture hardcodes that source, so "still on screen" is
not evidence the keys were missed; acceptance is judged by the ready tokens
alone.
Two existing tests asserted the old shape and are updated, not weakened:
b19's "Escape branch stays" now looks for it in claude's adapter, and c1b's
"Enter once per iteration" becomes "never twice for one frame", which the
cooldown satisfies strictly more tightly.

A MAM script often runs inside one herdr server's pane (the orchestrator's)
while targeting another (the isolated MAM server). The pane exports
HERDR_WORKSPACE_ID, HERDR_PANE_ID and HERDR_TAB_ID, and those ids only mean
something on the server that issued them. They reached the scope filters as a
foreign workspace, whose fail-closed miss (ISSUE-3 / F-2b) reports a live
session as absent: has-session, kill-session, agent prompt and the delegate-job
preflight all answered "no such session". Reproduced on Linux and macOS in the
#23 comments, worked around until now with `env -u` at every call site.
mam_herdr drops the three ids for a call aimed at a named server other than the
caller's own. Scope then falls back to .mam/herdr_workspace_id and finally to
server-global, which is what _herdr_ws_scope already does. `default` is not a
crossing: it is the sentinel for "pass no session flag", so herdr answers on
the ambient server, which for a caller in a pane is that caller's own. A caller
outside any pane keeps an exported scope, so H-18/H-21/H-23 keep their meaning.
The fix lives in mam_herdr, not in the shim heredoc: that heredoc is
materialised into $WORKSPACE_ROOT/.mam/shim/herdr, one file shared by every
checkout bound to a control plane and rewritten on every herdr call, so editing
it would put unreviewed code in the control root and let two checkouts
overwrite each other. S11 fixes that invariant.
lib_py/loop/watcher.py builds its own herdr argv and is the one path that does
not go through mam_herdr, so it applies the same rule via scoped_env.
