# Cheap static gate for this library (no database, no coverage). Runs from the
# root `make check`, which loops app then blogex.
#
# Sensor slot: add `credo` once the "credo strict, tuned config (both apps)"
# yak lands blogex's credo dep + .credo.exs. Do not list it before then — a
# gate that claims a check it did not run is worse than no gate.
check: compile format

# Per-app precommit loop: same target name and alias shape as app/, so both
# apps share one habit (compile --warning-as-errors, format, test).
precommit:

# Sync dependencies
deps:
	$(MISE_EXEC) mix deps.get

# Compile the project (warnings are fatal)
compile:
	$(MISE_EXEC) mix compile --warnings-as-errors

# Run the test suite
test: deps
	$(MISE_EXEC) mix test

# Run the suite once with coverage exported, so the coverage floor check (and,
# later, CRAP) reads the export instead of running the suite a second time.
# Stale exports are removed first: the floor must never report an older run.

	rm -f cover/*.coverdata
	$(MISE_EXEC) mix test --cover --export-coverage default

# Enforce the coverage floor (mix.exs -> test_coverage) from that export. No
# test run. `mix test.coverage` exits 0 when it finds no export at all, so the
# guard below is load-bearing: a floor check that did not run must not pass.

# Sensor slots, cheapest first. Add a sensor as its yak lands, both as a target
# and to VERIFY_SENSORS — that variable is the single source of truth for what
# this target reports as wired.
#   - coverage   (yak: coverage floors + framework-glue exclusions policy)
#                  WIRED below (test.coverage + coverage).
#   - crap       (yak: CRAP scores with ex_crap (both apps))
#   - mutation   (yak: mutation testing with muex — a sensor, not a gate)
#
# The suite runs FIRST: it is what produces the coverage export that the
# sensors below read. (Sampling and reporting are separate steps because
# `mix test --cover --export-coverage` exports instead of printing a summary,
# and reporting through `mix test.coverage` keeps it to one suite run.) Sensors
# still run cheapest-first among themselves.
