The session-title snapshot exposed a real activation race: ui-trajectory
and ui-question register into conversation-declared slots but only
injected 'slots', so nothing ordered their applies after ui-conversation's
— register() into the undeclared slot threw and the entry FAILED. Both now
inject 'conversation' as an ordering edge (documented as such; specs stub
the service where the bench declares the slot itself).
Review-bot findings, all three applied: the module loader's load sink
cross-checks the handoff id against the arriving row (a mis-stamped bundle
can no longer register under another entry's identity); the default
execute seam removes the inline script node right after its synchronous
execution (repeated HMR rebuilds no longer accumulate dead nodes); a
throwing onRebuilt subscriber is contained per-listener and routed to
onError instead of escaping the fs.watchFile callback.
The composer seat lives in a fixed-height conversation column with
overflow hidden, so a long question batch pushed the footer actions out
of reach (review r3635427112). The card now flexes with a viewport-
relative max-height, the option list is the scrollable region (ChatView
list pattern: min-height 0 + overflow-y auto), and header/footer are
flex-shrink 0 so progress, navigation, skip, submit, and cancel stay
reachable.
Verified in headless chromium against this sheet (900x600 viewport,
30-option batch): card capped at 360px (60vh), the option list scrolls
(scrollHeight > clientHeight), and the footer submit/skip buttons stay
inside the viewport. jsdom cannot assert layout; the playwright smoke
follow-up tracks composer scrolling with the existing debt.
AskUserQuestionItem.detail is part of the user-interaction seam contract
but the web frame schema dropped it and the composer never rendered it
(review r3635427108). askUserQuestionItemSchema now forwards detail, the
composer renders it under the title in the description text style, and
the fixture's multi-select question carries one.
ClientContext types ctx.slots as always present (inject-declared service);
the unnecessary-condition lint rule rejects the dead guard and its
fail-loud test premise. Load-order failure still surfaces loud through
the undeclared-slot registration path, covered by the remaining case.
Contract face moves to contract/slots.ts (PropsRuntime composition off the
conversation SlotMap entry, flat answer/cancel injected share); apply takes
the ui-sidebar terminal form (strict need() service reads, ctx.effect-wrapped
single register, framework-resolved sessionId); tests upgrade to the terminal
style (props-direct component specs with standard-kit stubs, real-registry
apply spec with children-declared slot, fiber-teardown case).
