- Added transcriptMessageComponents to every InteractiveMode ctx test literal; #6033's reuse cache made the field required and addMessageToChat populates it unconditionally.
- Wired setTodoPhases into the eager-todo ToolSession fixture to mirror sdk.ts; the test relied on the stale message_end todo replay #6148 removed.
- Omit Next from the guest multi-select ui-request options until at least
one option is checked or a custom answer exists, mirroring the local
dialog's disabled-Next gating. The remote select has no disabled-row
concept, so Next is omitted rather than dimmed (PRRT_kwDOQxs0bc6OFbDW).
- Add the bottomBorder(1) term to the ask dialog's fixed-row budget so the
rendered dialog no longer overflows the viewport by one row
(PRRT_kwDOQxs0bc6OFbDY).
- Add focused tests: guest wire-level Next gating round trip, and dialog
height <= viewport assertion.
- Replace #requestGuestUiString's string|"unavailable"|undefined channel
with a tagged GuestUiResult ({answered}|{cancelled}|{unavailable}) so a
guest answer literally equal to "unavailable" no longer collides with
the transport-unavailable sentinel (PRRT_kwDOQxs0bc6OE3gN).
- Cap in-body question header rendering to MAX_HEADER_ROWS with ellipsis
truncation so long/multiline questions cannot push options off-screen
(PRRT_kwDOQxs0bc6OE3gS).
- Guest Other editor cancellation now continues the loop (multi) / re-shows
the select (single) instead of cancelling the whole ask
(PRRT_kwDOQxs0bc6OE3gU).
- Disable the Next row on a single-question multi-select until at least one
option or custom input is chosen, preventing empty-result submission
(PRRT_kwDOQxs0bc6OE3gY).
- Introduced the `CollabGuestUiResult` type to distinguish between answers and unavailable states during guest UI requests.
- Updated the remote dialog race logic to ignore unavailable guest results and fallback to the local host dialog.
- Centralized the `FakeWebSocket` and `InMemoryRelay` test infrastructure into a shared test helpers file.
- Cleaned up duplicate mock implementations and updated existing test suites to utilize the shared in-memory relay helpers.
- Prevents connection hangs during initial join by immediately failing when a host rejects a guest prior to welcome.
- Short-circuits the connection welcome timeout upon receiving a pre-welcome error frame.
- Surfaces exact protocol mismatch and hello rejection reasons directly to the joining guest interface.
- Ensures `CollabGuestLink` and `GuestClient` transition immediately to ended/failed states with host error details.
- CollabGuestLink now handles ui-request/ui-request-end frames via the existing hook selector/editor dialogs and round-trips ui-response; cancellation, resync replay, and read-only peers are handled.
