idx-cli/scripts/live-smoke.sh

#!/usr/bin/env bash
# Live provider drift check: runs shipped commands against real MSN, Yahoo,
# and IDX endpoints and validates the JSON output shape. Deterministic CLI
# behavior is covered by tests/cli.rs and tests/golden.rs; this answers "do the
# upstreams still look the way our parsers expect?"
#
# With --compare <old-idx>, every case also runs the old binary back to back
# and fails on any difference in exit code or JSON structure, and on any value
# difference for slow-moving data (see "Live A/B check" in docs/DESIGN.md).

Usage: scripts/live-smoke.sh [options]

Options:
  --group <stocks|ownership>  Restrict to a group. Repeatable. Default: both
  --symbol <ticker>           Primary ticker. Default: BBCA
  --bin <path>                Use an existing idx binary (skips cargo build)
  --compare <old-idx>         Also run an older idx binary and diff the results
  --dry-run                   Print cases without running them
  --help                      Show this help
