Danny Avila b39ec16ff0 🔌 fix: Preserve Ephemeral MCP Selections Across Model Switches (#13697) ... The no-spec branch of `useApplyModelSpecEffects` (added in #11796) reset `ephemeralAgentByConvoId` to null on every `newConversation` call when model specs are configured. On in-place model/endpoint switches (modular chat, same conversation or new-chat draft), BadgeRowContext never refills from localStorage — its init effect only re-runs when the storage suffix or spec changes — so the MCP selection (and tool toggles) were silently dropped from subsequent request payloads while the MCP badge kept displaying them. Reset now only happens on context transitions (leaving a spec, or moving to a different conversation key), where a BadgeRowContext refill is guaranteed; in-place non-spec switches preserve the ephemeral agent. - Gate the no-spec reset on `prevSpecName` / `prevConvoId`, passed from `newConversation` via a snapshot read of the pre-switch conversation - Add jest coverage for all five branches of the no-spec path - Add e2e spec asserting `ephemeralAgent.mcp` stays in the chat payload after a new-chat model switch and after regenerate on a switched conversation (verified failing before the fix, passing after) - Add non-spec "Mock Provider D" endpoint to the e2e config so tests can switch between two real ephemeral endpoints; widen `MockEndpoint` type		2026-06-11 18:13:41 -04:00
