 - ACP/session history: persist transcripts for successful ACP child runs, preserve exact transcript text, record ACP spawned-session lineage, and keep spawn-time transcript-path persistence best-effort so history storage failures do not block execution. (#40137) thanks @mbelinky.
 - Browser/CDP: normalize loopback direct WebSocket CDP URLs back to HTTP(S) for `/json/*` tab operations so local `ws://` / `wss://` profiles can still list, focus, open, and close tabs after the new direct-WS support lands. (#31085) Thanks @shrey150.
 - Browser/CDP: rewrite wildcard `ws://0.0.0.0` and `ws://[::]` debugger URLs from remote `/json/version` responses back to the external CDP host/port, fixing Browserless-style container endpoints. (#17760) Thanks @joeharouni.
+- Browser/extension relay: wait briefly for a previously attached Chrome tab to reappear after transient relay drops before failing with `tab not found`, reducing noisy reconnect flakes. (#32461) Thanks @AaronWander.
 - Context engine registry/bundled builds: share the registry state through a `globalThis` singleton so duplicated bundled module copies can resolve engines registered by each other at runtime, with regression coverage for duplicate-module imports. (#40115) thanks @jalehman.
