# Stop hooks only. When the host named the project and that site is cold,
# do not read stdin or load the library. Claude and Cursor release by
# silence. Codex documents JSON on every Stop that exits 0, so an unarmed
# Codex stop prints {"continue":true} and leaves. Only the layout table is
# loaded, to find the markers wherever the workspace's layout keeps them.
# Set NS_COLD_STOP_HOST=claude|codex|cursor before sourcing.
#
# No host project env means the payload cwd must be read; do not guess $PWD.
