# Install joule-coded as a launchd *user agent* in the GUI (Aqua) domain.
#
# Why the GUI domain and not `nohup … &`: on macOS a process detached from a
# login session is denied permission to *initiate* outbound local-network
# connections (it can still bind/accept). The headless worker's federation
# transport (Phase 3) needs to dial peers, so it must run session-attached or as
# a launchd agent in the GUI domain. `launchctl bootstrap gui/$(id -u)` gives it
# that context; `nohup`-over-SSH does not (we root-caused this — see
# open-standards lockstep-quic/MACOS_LAUNCH_CONTEXT.md).
#
# Usage:
#   JOULE_CODE_ROOT=/path/to/repo \
#   JOULECLAW_L3_MODEL=/path/to/model.gguf \   # optional; enables the L3 tier
#   ./install-joule-coded.sh
#
# Override any of: JOULE_CODED_BIN, JOULE_CODE_ROOT, JOULE_CODE_SOCK,
# JOULECLAW_L3_MODEL, JOULE_CODE_GRANT_TIERS.
