Nerves Gate firmware

The nerves_gate device application: network, Tailscale, equipment, bus, LED and SSH domains, the gateway LiveView UI, the device SDK backend and the trusted OTP application runtime. EC100 (MIX_TARGET=ec100) and QEMU (MIX_TARGET=x86_64) build the same application. Host builds provide shared gateway UI modules for simulator tools, quality checks and assets; they start no device services.

The Hex package is consumed on the host by nerves_gate_sim. Device firmware builds run from the product checkout and resolve only their selected system's Git source and GitHub artifact. Target-specific tailscaled binaries are not included in the Hex payload. Firmware releases provide a separate x86_64 .fw image for app-development workspaces.

Use repository-root mix setup and mix dev for product development. Firmware-specific commands run inside this directory, never through a root firmware alias. Set NERVES_GATE_LOCAL_DEPS=1 to use the repository's SDK and systems:

NERVES_GATE_LOCAL_DEPS=1 mix ci                 # quality gates
NERVES_GATE_LOCAL_DEPS=1 mix assets.build       # commit priv/static/assets/
NERVES_GATE_LOCAL_DEPS=1 MIX_TARGET=ec100 MIX_ENV=prod mix firmware
NERVES_GATE_LOCAL_DEPS=1 MIX_TARGET=x86_64 mix firmware

Integration scenarios live in test/scenarios/ and run on the QEMU simulator. See the repository README and guides.

This package has its own VERSION and CHANGELOG; releases use firmware/vX.Y.Z tags.
