# Issue 15136: current-main runtime reproduction SHA: e27a03e94d (origin/main fetched 2026-10-21). Linux x64; Node 24.21.0; Codex CLI 0.163.0. Command: `env -u T3CODE_HOME ./node_modules/.bin/vp run dev --home-dir /home/ubuntu/wt/issue-15136/.t3 --no-seed` Ports: web 8038, server 16078. Paired real web client through the T3 Browser panel. Codex gpt-6.1-sol parent delegated Claude claude-opus-5-5 and Codex gpt-6.1-sol children asynchronously with shared isolation. Each called worktree status then handoff; continuation requested pwd and one proof file. The tools selected managed paths under .t3/worktrees/server; supplied sibling path did not determine destination. No implementation changes or manual recovery. ## Child runs | Provider | Run | Status | Requested | Started | Completed | Queue held | |---|---|---|---|---|---|---| | claudeAgent | 1 | failed | 2026-10-21T10:06:10.250Z | 2026-10-21T10:06:10.331Z | 2026-10-21T10:06:28.704Z | None | | codex | 1 | interrupted | 2026-10-21T10:06:10.392Z | 2026-10-21T10:06:10.568Z | 2026-10-21T10:06:26.067Z | None | | codex | 2 | completed | 2026-10-21T10:06:26.014Z | 2026-10-21T10:06:32.602Z | 2026-10-21T10:06:39.881Z | None | | claudeAgent | 2 | queued | 2026-10-21T10:06:28.682Z | None | None | True | ## Observed task_status over time - 2026-10-21T10:06:10.580Z: Claude: status=running, hasPendingChildRuns=False, latestTerminalStatus=None, summary=None - 2026-10-21T10:06:10.746Z: Codex: status=running, hasPendingChildRuns=False, latestTerminalStatus=None, summary=None - 2026-10-21T10:06:34.371Z: Claude: status=failed, hasPendingChildRuns=False, latestTerminalStatus=failed, summary=The provider event stream closed unexpectedly.

Codex: initial run interrupted; continuation completed and proof file contained destination cwd. Parent received a premature failed result for Claude, and a completed result after Codex run 2. After capture, the owned dev server was stopped and its two throwaway worktrees removed.
