# Dispatch — codex/pi arm Spawn a worker via `doctrine worktree fork --worker` + subprocess spawn. Drive loop lives in the [`/dispatch` router](../dispatch/SKILL.md). ## Spawn — codex arm ```sh doctrine worktree fork --base "$B" --branch "$BR" --dir "$D" --worker \ || { echo "fork failed: $?" >&2; exit 1; } env -C "$D" DOCTRINE_WORKER=1 codex exec "<pre-distilled prompt>" ``` Confined (bwrap); run the fork, check `$?`, then spawn. The worker inherits the ambient env and compiles into its own in-tree `$D/target` (no env contract). ## Spawn — pi arm (RPC mode) ```sh doctrine worktree fork --base "$B" --branch "$BR" --dir "$D" --worker \ || { echo "fork failed: $?" >&2; exit 1; } cp AGENTS.md "$D/" \ || { echo "AGENTS.md copy failed: $?" >&2; exit 1; } PI_FIFO=$(mktemp -u) && mkfifo "$PI_FIFO" { printf '%s\n' \ '{"type":"set_auto_retry","enabled":false}' \ '{"type":"prompt","message":"<pre-distilled prompt>"}' sleep 300 } > "$PI_FIFO" & timeout 300 env -C "$D" DOCTRINE_WORKER=1 \ pi --mode rpc --thinking off --session-dir "$D/.pi-session" \ --no-extensions --no-skills --no-themes \ --offline --approve --tools read,bash,edit,write,grep,find,ls \ < "$PI_FIFO" rm -f "$PI_FIFO" ``` Same confinement as codex arm; fifo keeps stdin open (pi RPC exits on EOF). `sleep 300` keepalive, `agent_end` gives typed completion. Ignore `extension_ui_request` widget events from installed packages. ## Boundary recording At the `conclude` prescription (`doctrine dispa
