Two issues the Stacks supervisor reported after the move: its observations o-20261104-174501777 and o-20261104-185328718, both verified in its log.

What

• scripts/devteam.mjs, worker/planner launch: the typed agent command is prefixed with env -u … for each agent-session marker found in this process's environment or tmux's global or session environment. SESSION_MARKERS matches CLAUDECODE, CLAUDE_CODE_* and CLAUDE_PID. Owner settings such as CLAUDE_CONFIG_DIR and CLAUDE_EFFORT aren't markers and stay. env -u works whatever the window's shell is (sh, zsh, fish). Both agent_command and resume_command are covered.
• process/supervisor.md §3 step 8: the approval and ruling acts are written as act --class approve-spec --refs <id> (and likewise for approve-plan, contract-ruling and approve-design-change), not as commands of their own. The refusals the line describes are act's own checks (devteam.mjs cmdAct).
• test/kit.test.mjs: the fleet-park test starts its new-machine worker from a supervisor environment carrying CLAUDECODE and CLAUDE_CODE_CHILD_SESSION, then asserts that the pane's command strips both and keeps CLAUDE_CONFIG_DIR.

Why

• On the new machine, the supervisor created the devteam tmux server from inside its Claude Code session. Every worker inherited CLAUDE_CODE_CHILD_SESSION and the messaging-socket variables, so Claude Code treated each worker as a child session and saved no transcript. Spend went unmeasured until the supervisor unset the variables by hand and relaunched the three workers.
• A supervisor following §3 literally ran devteam.mjs approve-spec and got "unknown command".

Authority

This adds no new path. It removes inherited variables from a worker's agent process, and the worker's role and policy still come from the DEVTEAM_* export and the --settings file, as before.

Harness-agnostic

The marker list names Claude Code's variables because those are the ones observed. Codex and OpenCode markers join SESSION_MARKERS as they're found. An unknown harness is unaffected.

Migration

None.

Review (upstream loop, author's own PR):

• Claims verified against the Stacks log (o-20261104-174501777, o-20261104-185328718) and the kit. cmdAct holds the refusals that supervisor.md §3 describes; no approve-* command exists.
• Authority: this only removes inherited variables from a worker's agent process. Role and policy still come from the DEVTEAM_* export and --settings. No path to the owner.
• env -u is shell-independent. Owner settings (CLAUDE_CONFIG_DIR) are kept, and the test asserts it.
• Tests: CI 18/20/22/24 green; local Node 24.14.1 42/42.
