Every expandable tool row shares one interaction (whole-row toggle,
icon-to-chevron hover preview) and one expanded body: an IN/OUT
gutter-labeled card with per-section 150px scroll caps and sticky labels.
toolRowModel derives result output and the error first line, terminalFailed
surfaces a failing exit as the collapsed row's red dot, a hover Inspect
pill jumps to the call's trajectory record through a one-shot store
handoff, and the chat view keeps its scroll offset across view switches.
The seat's height publisher needs a ResizeObserver stub in every spec that
renders ConversationRoot (jsdom has none), and the two branch-tail StatsLine
assertions move to the grouped detail-row output.
The #921 selector change and the duplication gate both first ran against
this branch after the merge made it MERGEABLE: assembly-surfaces still
queried the retired data-sample="todo-row" hook (the composed TodoRow
carries ToolRow's data-tool attribute instead), and the redesigned
QuestionComposer duplicated the custom-draft onChange/onKeyDown pair
across its inline input and optionless textarea. The spec now anchors on
data-tool="todo_write", and the composer shares one draftCustom /
continueFromCustom handler pair (Enter continues, Shift+Enter stays a
newline, IME composition stays inert).
Sink the behavior previously held only by the apps/web jsdom snapshots
into the owning packages, each bench mounting the real apply on the
production slot machinery with fixture-fed data:
- ui-conversation/assembly-surfaces: the todo_write turn reaches both
product surfaces (keyed toolview row + dock plan strip via the todos
projection) and the strip follows projection retirement; the keyed
bash row carries its resident terminal card while the fallback row
reaches one through expand; the locked no-session view state; the
composer textarea surviving the blank→active conversion as the same
DOM node; the promptError alert strip with the machine-restored
draft; one summary update re-labeling the breadcrumb.
- ui-workspace/rename-assembly: the session-rename chain (row menu →
dialog → the injected renameSession hop → ISession.rename with the
edge-trimmed draft → dialog close and row re-label from the list),
plus the rejected arm keeping the dialog open with the error.
- runtime/workspaces-service: startInitialSelection — connects the
recent Workspace once both baselines are ready and opens the session,
stays idle with a current session or no recent target (double start
fails loud), and a failed connect returns to waiting and retries on
the next list change.
Component-level arms stay in the existing package suites; these files
prove only the assembled wiring.
