Phase 0 of docs/DESIGN.md, before any refactor code:
- tests/golden.rs runs every case in tests/golden/cases.toml (126
outputs across help, completions, config, cache, all stocks commands
on MSN and Yahoo mocks, error paths, and ownership queries on a seeded
fixture DB) and compares exit code, stdout, and stderr byte for byte.
Regenerate only with UPDATE_GOLDEN=1 for a reviewed output change.
- scripts/live-smoke.sh --compare <old-idx> runs each live case with
both binaries and fails on differing exit codes, added/missing/retyped
JSON keys, or changed values for slow-moving data.
- Exclude golden files from the whitespace/EOF pre-commit fixers, which
would otherwise rewrite pinned help output.
Both gates were fault-injected: a one-word table change fails exactly
the three history goldens, and a binary dropping profile.long_name fails
only the profile live comparison.

Accepted design for extracting idx-core as the shared data layer, the
agent-native CLI output contract, idx-mcp tools, packaging, and the
parity gates (golden output tests plus live A/B check) that the
refactor must pass before merging to main.
