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.

The cache stores normalized summaries, so one written before buy_value and
sell_value existed read back without them: bandar gave null readings (the
table said "No trades.") for a week, and an investor-filtered entry lacked
its totals. Summaries now cache under ipot-broker-v2, so an old-shape entry
is never served; offline it is a cache miss, online it is fetched again. A
CLI test seeds an old entry and checks both, in JSON and table output.

IPOT's investor filter splits each broker row by client domicile, but its
footer then gives only that side's buying (BBCA 2026-10-16: foreign 1.7 T,
domestic 4.9 T of 6.6 T). The foreign net gives the selling on all boards:
foreign 1.7 + 2.3 = 4.0 T (IDX: about 3.95 T regular), domestic
4.9 - 2.3 = 2.6 T.
- BrokerSummary gains buy_value and sell_value: the total for all
investors, the footer and the derived selling for one side (selling is
null with a board filter, where the net covers other boards).
- Bandar weighs the top N buyers' share of the value bought against the
top N sellers' share of the value sold, so `--investor foreign|domestic`
reads that side alone; for all investors the readings are unchanged.
One side on one board is refused, as there is no selling to weigh.
- Tables print what the side bought and sold; fixtures for foreign and
domestic on all boards were recorded from IPOT.

`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.

`idx stocks broker SYMBOL` shows the top 10 buyers and sellers of a stock
by lots for the latest session with trades, one `--date`, or a
`--from`/`--to` range, filtered by `--investor` and `--board`. The MCP
server exposes the same as get_broker_summary.
- Range and filter parsing lives in idx-core (BrokerRange::from_args,
FromStr for the filters), so both frontends accept the same input.
- Without dates, the latest session is found by walking back over
weekdays; offline, uncached days are skipped.
- Table output lists foreign and state-owned brokers, and says when the
source rounded figures.

With fd=F or fd=D, IPOT's footer covers only that side's buying: BBCA's
foreign/regular summary for 2026-10-16 gives T. Val 1.6 T while its top
seller alone sold 2.0 T. Passing it through as the range total gave
consumers a denominator smaller than one listed broker, so total_value,
total_lots and average_price are now null for an investor-filtered summary.
The page-to-summary step is a pure function, tested on both fixtures.

Adds a BrokerSummaryProvider capability served by Indo Premier's public
broker summary page: the top 10 buyers and sellers of a stock by lots over
a date range, with totals. No login or key.
- api/ipot: pure parser (decimal scaling of `1.6 M`-style figures), a
client that retries the server's spurious 404s, and a fixture mock.
- broker: Broker::summary/latest over the cache (7 days for closed ranges,
5 minutes for today), range checks, and IDX member names bundled from
GetBrokerCodeList.
- foreign_net_value is null for filtered summaries: the source does not
apply the filters to it.
The endpoint's behavior was first mapped by fzn0x/idx (MIT).
