llm-exports-sync.yml

# Deterministic sync from .cursor to .llm/exports (see scripts/llm/ and docs/development/llm/).
# Does not use cloud LLM APIs. Export is plain Node (no root npm install); see package.json llm:exports:sync.
# PRs to develop are not gated on .llm/exports matching; after merge, this workflow (push to develop) updates branch `llm` and its rolling PR. Use `npm run llm:exports:check` locally if you want to assert a branch is in sync.
