# desklock — one entry point for a three-component repo.
#
#   firmware/   ESP-IDF application for the device. No tests, no release flow.
#   gateway/    Python service on :8600. The only component with a test suite.
#   sim/        a static page that mimics the device face in a browser.
#
# This lives at the root and the components have no Makefiles of their own, so
# `make test` means the same thing wherever you are standing. A per-component
# Makefile makes it mean "some of the tests" depending on your working
# directory, which is the `git -C` failure in another costume (D-27).
#
# Paths resolve here rather than in callers (D-10). Two of them bite:
#
#   ESP-IDF is invisible until export.sh is sourced, so `idf.py` is
#   "command not found" for anyone who forgets — the same class of failure as
#   the four tool-resolution misses recorded in D-24. The firmware targets
#   source it themselves.
#
#   `python3` on this host is 3.8, which cannot parse the gateway's sources.
#   PYTHON names 3.12 explicitly and is overridable for other machines.
