# Decision test for `sf-context feedback-nudge` + `record-feedback-decision` (#277).
#
# The feedback loop is the suite's first step toward an off-machine data path, so
# its gate must be provably default-OFF and its trigger provably self-limiting.
# This test asserts, fully offline (no org, no model):
#   - gate OFF (SFDX_FEEDBACK unset) → always silent, regardless of transcript
#   - gate ON + substantive work in the transcript → exactly one nudge
#   - gate ON + same session again → silent (one nudge per session)
#   - gate ON + no substantive work → silent
#   - every response is non-blocking (continue:true, no permissionDecision)
#   - record-feedback-decision persists the opt-in choice
#
# Run: bash plugins/sfdx-core/test/feedback-nudge.test.sh
