# scripts/dev/cli_smoke.sh — v2.0.17 N.47 (TSK-N.31 closeout)
#
# Comprehensive real-CLI smoke matrix for the scheduler orchestrator.
# Codifies the 30-command sweep that surfaced G19/G20/G21/G22/G29 in v2.0.15.
# Each step is tagged with the FR / G-finding it covers.
#
# Usage:
#   ./scripts/dev/cli_smoke.sh           # run against localhost:8005
#   VDS_SCHEDULER_BASE_URL=http://other:8005 ./scripts/dev/cli_smoke.sh
#
# Prerequisites:
#   - Running scheduler container (docker compose --profile scheduler up -d)
#   - VDS_SCHEDULER_ENABLED=true (kill switch on)
#   - VDS_SCHEDULER_CAPABILITY=admin (for write ops; falls back to error path)
#
# Each test step prints PASS / FAIL / SKIP and a one-line summary. The script
# exits 0 only if every PASS-required step passed. Cleanup uses the platform
# capability to delete test artifacts.
