# _smoke-root.sh  -  resolve the pipeline tree for a smoke that must run in BOTH
# the repo checkout and an end-user install.
#
# Why this exists: the repo and an install have different shapes.
#

# A smoke that hardcodes `REPO_ROOT="$(dirname "$0")/../.."` and then reads
# `$REPO_ROOT/pipeline/...` resolves to `$HOME/pipeline/...` once installed, so
# every path check fails. Whoever ran it sees a red report and concludes the
# install is broken. Source this file instead and read the MA_* variables.
#
# Usage (from any script in pipeline/scripts/):
#   . "$(dirname "${BASH_SOURCE[0]}")/_smoke-root.sh"
#   grep -q needle "$MA_REFS/phases/phase-4-review.md"
#
# Exports:
#   MA_LAYOUT     "repo" | "install"
#   MA_ROOT       repo root, or the install root (~/.claude)
#   MA_SCRIPTS    directory holding this script
#   MA_SCHEMAS    JSON schemas
#   MA_REFS       multi-agent-refs
#   MA_COMMANDS   slash-command tree
#   MA_SKILLS     skills tree
#
# Every exported directory is verified to exist; a missing one is left empty so
# the caller can skip that check rather than report a false failure.
