# Run the claw and the web UI together against scratch state — the quick
# debug loop. Nothing here touches your real rhema config or sessions:
# the daemon gets a throwaway config under $RHEMA_DEV_DIR (default
# /tmp/rhema-dev), persisted across runs so sessions survive a restart
# of the script; wipe the directory for a clean slate.
#
# Usage:
#   scripts/dev.sh            # real provider (CLAW_DEV_PROVIDER, key from
#                             # the provider's env var; default google)
#   scripts/dev.sh --mock     # zero credentials: canned streamed replies
#
# The UI proxies /v1 to the claw, so one URL matters:
#   http://localhost:3000
