* wip(layout): applyDefaultTabs command in the layout model (dark)
* wip(layout): applyDefaultTabs takes the window's proposed ids; main refuses a taken one
* wip(layout): main closes or keeps an exited split pane by the window's rule (dark)
* wip(layout): a create or split sent again after its close is refused (dark)
* wip: typed test doubles
* wip(layout): main writes a worktree's default tabs in one command and starts them, window or none (dark; twin e)
* wip(layout): main writes a worktree's default tabs in one command and starts them, window or none (dark; twin e)
* wip(layout): main provisions setup and default tabs even when the agent fails to start; no window takes over (dark)
* wip(layout): pane start status in frames; a failed start keeps its pane; a terminal close stands after a failed write (dark)
* wip: lint fixes (max-lines, test throws)
* test(layout): a terminal close stands after a real failed profile write; switch off still refuses
* fix(layout): checked types in the close-failure rule and its tests
* fix(layout): a failed start keeps its pane whatever failed; default tabs start once; a tab's last pane keeps its card (dark)
* test(layout): the agent's kept pane counts as the workspace's terminal; main starts it whatever failed
* fix(layout): the switch-off create path gains no await
* fix(layout): a failed start never writes back a pane the user closed (dark)
* fix(layout): a failed start's pane goes through main's create rules, so a closed tab stays closed (dark)
* test(layout): D1a's switch-on close tests assert the intent main receives (both builds)
* test(layout): the close fixture answers main's command without naming the method
* fix(layout): a re-created pane binds as designed; the id-only ratchet reads a shared import (dark)
* fix(layout): a pane's start status may sit on a pane still bound to its old terminal (dark)
* fix(layout): a pane's start status ends when its pane binds again by any path (dark)
* test(layout): same-id restore ends a status; a replayed split brings back a closed pane by design
* fix(terminal): keep shipped exit and default-tab behaviour with the layout switch on
An exited pane closes through the legacy retirement unless the keep rule holds; the
default tab's title and color still reach the window and the phone's live tabs.
* fix(terminal): one id guard for every pane write; keep panes on an unvouched -1
Main's taken and closed-id guard now runs where every pane write goes, so a runtime create
replayed after its tab closed is refused before it spawns. An exit code nothing vouches for
keeps the pane, as the window does; a kept pane sends the phone no retirement. Converts the
switch-on tests that asserted the deleted window hand-off and title bridge.
* fix(terminal): keep the closed-tab guard on every pane write, held-id checks on client commands
A paired host starts each pane of a client's tab as a create under the tab's id, so a held tab
id is refused only for a client's own layout command.
* fix(terminal): a provider-reported -1 keeps the pane, as the window does
Only a requested stop or a host-confirmed death closes a pane on a negative exit code. Pins that
the closed-tab guard never fires in the shipped build.
* chore(terminal): satisfy the exhaustive-switch and test typing checks
* test(terminal): give the replay test's live process a cwd
