From the 0.4.0 release review (Codex):
- IPOT pages with a short row, a rank out of order or a broker after a
blank row are parse errors; skipping a row shifted later brokers up a
rank and could flip a bandar reading (-2425 bps to -66 bps).
- A tbody end before its start is a parse error, not a panic.
- An IPOT page that echoes other dates than requested is rejected before
it is cached, so one session's figures never pass as another's.
- An IDX trading summary with rows for other days only is an error, not
an empty session cached for 30 days.
- Empty sessions count toward a flow's fetched_at and stale.
- The bandar imbalance uses checked i128 arithmetic: past i128 there is
no reading instead of a wrapped one.
- The bandar table prints "No trades." only when no broker traded.

`idx stocks flow` now reads IPOT by default, which needs nothing installed:
per session, the all-investor broker summary gives the value traded and
the foreign one gives foreign buying (its footer), the foreign net and
selling (buying less the net), across all boards, through the broker
summary cache. IPOT's foreign net matched IDX's estimate within 0.3 B on
BBCA 2026-10-12 to 16.
`--source idx` (and `source` on get_foreign_flow) keeps IDX's trading
summary: exact share counts, close and the non-regular share, behind
curl-impersonate and Cloudflare.
- ForeignFlowDay gains foreign_buy_value, foreign_sell_value and
foreign_share_bps for both sources (estimated at the session average
for IDX); ForeignFlow gains source, the value totals and rounded.
- The table lays out each source's figures; the live smoke runs both.

IDX's Value is regular-board turnover, so NonRegularValue / Value gave
non-regular over regular (BBRI 2026-10-14: 50.91%) instead of the share of
all trading (33.74%). non_regular_bps now divides by regular plus
non-regular value, with a regression test on that fixture. The docs now say
volume, value and the foreign figures are the regular board: IPOT's
regular total matches Value, and in a week of every stock no foreign figure
exceeded regular volume, even with non-regular volume above twice it.

`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.
