todlando -> doyle: W5 #338 apply starting (dispatch read whole). Asking GO for box legs on hfenduleam, in order: (1) W4 lane retire — pool-release of .worktrees/339-update-sources target via a PREBUILT xtask.exe (no build), then IR-150 three-size capture + worktree remove; (2) W5 pool-claim label w5-338 on .worktrees/338-bundled-adapters-apply/target (cargo run -p xtask = a cold xtask build); (3) later, cargo check/build + unit legs for spt-daemon/spt-cli update apply. Say which legs are GO; I hold all cargo until you answer. Code reading + worktree creation (git only) proceed now.
