Garry Tan 104652578b feat(sidebar): silent re-attach with scrollback replay (Commit 3 client side) ... Closes the v1.44 long-lived-sidebar loop end-to-end. When the WS dies for a transient reason (wifi blip, MV3 panel suspend, brief Chromium pause), the sidebar now silently re-attaches to the SAME claude session inside the server's 60s detach window. Scrollback replays cleanly; the user keeps typing without noticing anything happened. State machine: * New STATE.RECONNECTING covers the in-flight re-attach window. setState transitions out of this state reset reattachInFlight so a concurrent user action (Restart click, panel navigate) short-circuits cleanly. * Backoff schedule REATTACH_BACKOFF_MS = [1000, 2000, 4000, 8000] then 8s steady until REATTACH_WINDOW_MS (60s) elapses. Past that point the server has disposed our session and /pty-session/reattach returns 410 Gone. startReattachLoop(prevSessionId): * Posts /pty-session/reattach with sessionId. * On 200 with a valid 4-tuple, opens the post-reattach WS directly. * On 410 (lease expired) — short-circuits to ENDED. No retry; the user clicks Restart for a fresh session. * On 401 — sticky-aborts the auto-connect loop. Same defense as 25ef24e9 so we don't spam "Auth invalid" every 2s. * On network failure or other non-OK status — schedules the next backoff tick. openReattachWebSocket(terminalPort, attachToken, sessionId): * Mostly a clone of connect()'s attach wiring. Reuses the live xterm element — RIS clears the buffer cleanly when the agent's {type:"reattach-begin"} arrives, so the visual flash is minimal. * Handshake: on `{type:"reattach-begin"}` text frame → write `\x1bc` (RIS) to xterm + set nextBinaryIsReplay = true. The next binary frame IS the server-built replay payload (DECSTR soft-reset prefix + optional alt-screen re-enter + ring buffer contents). * If THIS reattach WS also dies uncleanly, recurses into another re-attach loop with the same sessionId — the server's detach window may still be open. State guard prevents runaway recursion. connect() + forceRestart() close handlers (existing): * Both updated to call startReattachLoop on transient close codes (anything other than 1000 / 4001 / 4404). Was just setState(ENDED). * Clean codes still bypass — re-attaching to a force-restart's pre-restart session would be the bug we're avoiding. Test (browse/test/sidepanel-reattach.test.ts): * 8 static-grep tripwires for the load-bearing properties: state constant, backoff schedule, /pty-session/reattach wiring, 410 short-circuit (no retry past lease window), 401 sticky-abort, reattach-begin → RIS handshake, all three close handlers route through the loop, clean-code bypass.
