# Substitutions are applied most-specific-first so a broad rule cannot

# NOTE: this script only sees git-TRACKED files (via git grep). Git-ignored
# trees — notably /deploy/ (see .gitignore) — are out of its reach and were
# scrubbed separately, by hand, with the same substitution set. A git-based
# completeness gate likewise cannot see them; verify those trees with a plain
# `grep -rniI scadalink <dir>`.

# Carve-outs (migration records): prior rename tooling/design, the DB-rename
# helper, this script itself, and the rename design + plan docs (which document
# the old→new mapping and would be self-corrupted by the substitution).
