# next/tests/smoke_app_pure.sh — Step 9b-pure smoke test.
#
# Mirrors §Step 9b structurally without TCP/curl/JSON. A trigger
# projection (Erlang fun) matches Note activities tagged
# "smoketest", constructs a derived TestEcho activity carrying
# the Note's CID via :echoes, and captures it into projection
# state. Proves the reactive-application mechanism — match-then-
# derive — works end-to-end through nx_kernel's broadcast.
#
# Cascade publication (the trigger actually publishing the
# derived activity back through outbox) is sidestepped to avoid
# gen_server reentrancy; the projection state is the proof point.
# 12 cases.
