Conversation
On a sandbox chat's host mirror the details panel read lineage from the host thread, which has none of the chat's subagents or delegated tasks; they are child threads on the sandbox's own server. The panel showed no Lineage section, so a long run looked stuck. When the sandbox's own thread is listed, the panel now reads its lineage from that thread on the sandbox environment this client is paired with.

Problem
A sandbox chat's details panel showed no Lineage section, so its subagents and delegated tasks were invisible and long runs looked stuck.
Change
The panel read lineage from the host mirror, which has no child threads. On a mirror whose sandbox thread is listed, it now reads lineage from that thread on the paired sandbox environment.
Scope and approval
Requested by the fork owner in a T3 Code session. Part of stack pingdotgg#43 on
feat/sandbox-environments; each PR is one fix and builds on the one below it.Verification
ThreadRelationshipsControl.browser.test.tsx: 10 tests passvp run check:changed omar/feat/sandbox-environmentspasses format, lint, knip, typecheck (42 packages) and react compiler; 582 of 583 tests pass, and the one failure (tailscaleScriptinsandboxSetup.test.ts) fails the same way on the base branchNot yet run in a real client; UI before/after captures will follow once the stack is installed.
