* reland(opencode): session continuity without the command-finished deferral (STA-4557) Relands #14866 (reverted in #14943) minus its `orca-runtime.ts` change, which is what caused the revert. ## Why the original runtime change was wrong `retirePtyAgentLaunchAuthorityAfterCommandFinished` deferred launch-authority retirement behind an async foreground read, on the premise that OpenCode emits `command-finished` while still in the foreground. Raw PTY capture disproves it: OpenCode emits no OSC 133 of its own, and Orca's shell wrappers emit exactly one `133;D` per pane — at OpenCode's exit — under both zsh and bash. The event being deferred past only ever fires at exit, which is exactly when authority should be retired. Both call sites stay on the synchronous `retirePtyAgentLaunchAuthority`. ## Why the deferral was unsafe `confirmPtyAgentExit` uses the same async-foreground pattern four lines away, but its early return means "don't record an exit" — conservative. The deferral copied that shape into a site where the early return means "don't revoke a secret". Same code, inverted consequence: every guard failed open, so a stale or racing read silently kept a finished session's authority alive, and the pane's persisted `launchTokenHash` was never scrubbed — so it rehydrated as `restored` authority after an app restart. ## Why the deferral's guards could not have worked `ORCA_AGENT_LAUNCH_TOKEN` lives in the PTY environment, so every process started in that shell inherits it — both sessions in a reused pane post the same token. A pane-lifetime bearer secret cannot be a session identity baseline, by construction, and `incarnationId` tracks the PTY, not the agent. The only field that separates sessions is the provider `sessionID`. ## What lands - Status/session-boundary work from #14866: opencode emits `SessionStart` for root sessions (mimo-code does not), launch-token fencing, and `SessionStart` as an opencode turn boundary. - The two `server.ts` fixes from #14941: re-fence a still-authorized pane on a tokened `SessionStart`, and restore mimo-code's explicit-prompt restart boundary (mimo emits no `SessionStart`, so opencode-only stranded its panes). #14941's re-poll hunk is dropped along with the code it patched. - Five regression tests in `opencode-finished-session-authority.test.ts`. They pass here and all five go red if the deferral is re-added. * chore: drop incidental reformatting of files unrelated to this PR
