# CASAN path resolver — single source of truth for harness / state / governance roots.
|
|
#
|
|
# Plan-01 restructure: physical file moves (`.specify/` -> `packages/casan-harness/`,
|
|
# domain -> `apps/okr/domain/`) are absorbed HERE. Callers must reference the
|
|
# CASAN_*_ROOT variables below instead of hardcoding ".specify/...", so a move only
|
|
# changes this file, not the 37+ scripts that consume the paths.
|
|
#
|
|
# Resolution rules (per root):
|
|
# - An explicit env override always wins (e.g. CASAN_HARNESS_ROOT=... bash foo.sh).
|
|
# - CASAN_HARNESS_ROOT derives from THIS file's own location: casan-paths.sh always
|
|
# lives at <harness-root>/scripts/bash/casan-paths.sh, so `../..` is the harness
|
|
# root wherever the tree is moved. No edit needed when the package relocates.
|
|
# - CASAN_APP_ROOT is found by walking UP for the `.specify` state marker.
|
|
# NEVER use `git rev-parse --show-toplevel`: in this checkout the git root is the
|
|
# repo PARENT, not the app dir, which would shift every path up one level.
|
|
#
|
|
# Idempotent and `set -e` safe: sourcing multiple times is a no-op; nothing here
|
|
# returns a non-zero status to a caller running under `set -euo pipefail`.
