# Seam: documentation completeness.
# Every service defined in a compose.yaml must have a matching documentation
# page in serverAppConfigs-docs/ and must be reachable from the index. This is the "docs first"
# contract of this repo: no service ships without documentation.
# The vault's second law, added 2026-10-18: ONE page per live LLM endpoint.
# A payload swap is an Eras row on that endpoint's page, never a page of its
# own -- a second file holding the same shape is the next thing to go stale.
