Phase 1 of docs/DESIGN.md:
- Output format resolves -o > IDX_OUTPUT > general.output > auto; auto
is a table on a terminal and JSON when stdout is piped or captured.
`config init` now writes output = "auto".
- JSON is pretty only on a terminal and compact otherwise. New `-o
jsonl` prints one array item per line with the same key order.
- No ANSI color when stdout is not a terminal (direct owo-colors calls
now go through output::style).
- `stocks quote -` and `stocks compare -` read symbols from stdin.
- Exit codes by class: 2 invalid input/config, 3 not found or cache
miss, 4 upstream unavailable, 5 unsupported, 1 other.
Golden changes are limited to those documented kinds and were verified
mechanically: JSON goldens are semantically identical, tables differ
only by removed ANSI codes and the column padding comfy-table had
reserved for them (cell contents identical), exit codes match each
error's class, and help/completions only gain the new --output values.
17 new golden cases cover auto, jsonl, stdin, and the new errors.
tests/cli.rs now pins IDX_OUTPUT=table in its harness (its tests assert
table text and run piped) and parses discover JSON instead of matching
pretty-printed whitespace.
Live A/B against main: 16/16 stocks cases identical; ownership discover
got IDX 403 on both binaries, now exiting 4 instead of 1 as intended.

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.
