# next/tests/http_publish_fold.sh — Step 9-pre-fold integration.
#
# Proves the full POST → publish → broadcast → projection-fold
# chain through HTTP without a real TCP socket. The kernel
# orchestrator threads :projections into the publish Context,
# so outbox:publish broadcasts the signed activity to every
# registered projection process and each fold runs.
#
# Step 9a/b smoke tests will exercise the same path via curl
# once Step 8b-start lights up actual TCP. 10 cases.
