… real #221 made the solver toggle do a real switch: the extension watcher sees {status:"switching"}, re-preps the session config, and restarts the opencode server. The webview survives that; its SSE stream does not. Nothing narrated the gap, so a deliberate tier change looked like a hang — the reconnect loop retries silently, which reads as an endless "thinking" wave. The old ConnectionBanner used to cover this, but it was unmounted on 2026-08-07 (f696388, a03aa04) after opencode#132's stuck pill, and the component has been dead code since. This does NOT reinstate it: the new banner speaks only for a switch the app itself requested, so a transient blip can never strand it, and whether general drops deserve a warning again stays an open question rather than one this change answers by the back door. - solver-switch.ts: the phase contract as pure helpers (requested → restarting → ready), matching solver-toggle.tsx's decision-helper split so it is testable without a DOM. sawDrop is latched — once the server has gone down, coming back up is the switch completing, not the request still waiting to be picked up. - Two expiry windows, not one. A request that has not taken the server down inside 12s is not going to (no extension host, stale binary, a write that never landed) and is abandoned quietly; a restart in flight gets the full 90s ceiling inherited from the stale #14 wizard's safety valve. Collapsing them into a single timeout would either strand the pill or cut a slow restart off mid-flight. - beginSolverSwitch() only MIRRORS a request, it never causes one. hp still rides the validated credential and piccolo rides POST /amicode/solver-mode — a banner that could initiate a flip would be the duplicate writer ADR 0001 forbids. Progress renders neutral and completion renders as the brand chip (--accent fill, near-black --accent-ink). That is the design system's rule, not a preference: #fff676 is ~1.1:1 on white, so yellow may never be a foreground on light — if it needs to be yellow there, it has to be a filled chip. Not included: the staged multi-step overlay from the stale #14. It polled GET /amicode/solver-mode, which does not exist (only POST shipped), and its hp stages assume an hp flip from a button — which #221 removed by design. Closes #78 follow-up.
📝 WalkthroughWalkthroughThe app now tracks solver-mode changes through shared phase helpers and displays a connection-aware status banner. HP and Piccolo selection paths announce transitions before sending existing mode requests. ChangesSolver switch status
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Consecutive solver-switch requests may cause the banner to show completion too early or disappear before the restart finishes, making a real switch appear complete when it is not. The changed CSS also has a lint error, so the PR is not merge-ready until these bounded issues are addressed. Sequence Diagram(s)sequenceDiagram

Reset lifecycle state for each solver-switch request.
beginSolverSwitch only updates target and startedAt. A second request can inherit sawDrop === true from a completed request.
If the target changes while connected, solverSwitchPhase returns "ready" immediately. If the target is unchanged, the existing ready timeout remains active because no effect tracks startedAt; it can clear the new request before the server drops.
Associate sawDrop, elapsed time, and the completion timeout with a request generation. Reset them for every beginSolverSwitch call. Add a lifecycle test for consecutive requests.
