# Fail when an agent-instruction or architecture document references a
# repository file path that no longer exists. Keeps CLAUDE.md / AGENTS.md /
# ARCHITECTURE.md / docs/ honest after refactors move code.
#
# Checked files: all tracked AGENTS.md, CLAUDE.md, ARCHITECTURE.md, and every
# Markdown file under docs/ (architecture, operations, testing, and the index).
#
# A reference is any token starting with crates/, rustfs/, scripts/, docs/,
# helm/, deploy/, .github/ or .config/ (at a word boundary, so helm/rustfs/...
# is not misread as rustfs/...) that ends in a known file extension. Tokens containing
# globs or placeholders, extensionless tokens (HTTP routes, directory
# references, org/repo shorthands), and lines containing URLs are skipped.
