validate-content.yml

# Content validation (Phase 60 / v1.44.0, D-108; EXP-039).
#
# Runs the validator on every pull request (and on pushes to main)
# so no broken or low-quality lesson set can land. The structural
# fields are validated against the canonical JSON Schema vendored
# under schema/ (a mirror of the pinned learn-content-engine
# release; source-of-truth chain: engine (canonical) -> this
# mirror), the quality minimums are read from
# schema/quality-rules.json, and the content-repo specifics
# (language pair, directory structure, non-Latin scripts) stay in
# the validator. Everything here reads only committed files — the
# validation itself works fully offline.
