`idx stocks flow SYMBOL` shows what foreign investors bought and sold of a
stock, session by session, from IDX's own daily trading summary: foreign
buy, sell and net volume, net value at the session's average price, and
the share of value traded outside the regular board, with range totals.
Latest 10 sessions by default (--days, at most 60) or --from/--to. The MCP
server exposes it as get_foreign_flow.
- api/idx: pure parser for GetStockSummary (rows dated another session
are dropped) and a provider over curl-impersonate's profile fallback
with a 30 s limit; Cloudflare passes only some fingerprints.
- flow: each session is cached whole by date, so other stocks' flows for
the same sessions need no request. Weekends are never requested.
- Idx::idx_code is shared by broker and flow for the .JK-only check.

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.

The 43-case mock smoke duplicated tests/cli.rs, which already runs the
real binary against fixture providers. Replace the flake's smoke-mock
check with a small packaged-cli check (version JSON, bash completions,
one mock quote), and cut scripts/live-smoke.sh from 672 to ~170 lines:
it now only runs shipped commands against live MSN/Yahoo/IDX and
validates output shape. Rewrite docs/SMOKE.md around the Nix gate and
the drift check.

Run deterministic installer and publisher checks in Nix, align dev and release dependency artifacts, narrow derivation inputs, and use content-aware CI cache keys. Replace duplicate Cargo gates with a Nix pre-push gate; validate JSON streams and cache data in representative packaged-binary smoke cases.
Clear the smoke cache before each cache-group warm case so the following offline and stale-cache checks always start from a fresh baseline instead of earlier group state.
Document the runner behavior in the smoke guide to make the cache-group sequencing explicit.
