# golangLAKEHOUSE — task runner.
#
# Sprint 0 acceptance gate (R-004): smokes are no longer documentation
# only — `just verify` is the single command that runs vet + tests +
# the 9 smokes. The pre-push hook calls this; CI calls this; reviewers
# call this. One source of truth.
#
# Usage:
#   just                  # alias for `just --list`
#   just verify           # vet + test + all 9 smokes (full gate)
#   just smoke <day>      # single smoke (d1..d6, g1, g1p, g2)
#   just smoke-all        # all 9 smokes only
#   just doctor           # dependency probe
#   just fmt / vet / test / build

# Go lives at /usr/local/go/bin per ADR-001 §1.x; prepend so every
# recipe sees it without depending on the parent shell's PATH.
export PATH := "/usr/local/go/bin:" + env('PATH', '')

# Default recipe shows the menu so `just` alone is a discoverable entry point.
