`idx stocks bandar SYMBOL...` reads the broker summary: for the top 1, 3,
5 and 10 brokers per side, buy value minus sell value in basis points of
value traded, with a signal from big accumulation to big distribution on
the headline tier (--top, default 5). Several symbols give a screen ranked
by that figure (at most 100, one request each), which pipes from
`stocks screen`. The MCP server exposes it as analyze_bandar (20 symbols).
- analysis/bandar.rs is pure and versioned (`top_concentration_v1`):
integer basis points, no figure missing counted as zero, buy/sell VWAP
from exact averages, and the brokers on both sides listed because their
gross figures overstate their direction.
- Thresholds (±5%/±15%) follow fzn0x/idx (MIT); docs call them heuristics.
- Invalid input fails a screen at once; other errors fail one symbol and
are warned about on stderr.

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).

Phase 2 of docs/DESIGN.md, no behavior change:
- crates/idx-core (library): api, analysis, cache, config file handling
and provider selection, curl_impersonate, error, ownership, runtime,
plus the shared test fixtures. clap derives are behind an optional
`clap` feature so the library does not require clap.
- crates/idx-cli (binary `idx`): cli/, output/, and IdxConfig (output
format and color resolution). Package and binary names are unchanged.
- config.rs is split: file read/write and validation move to core; a
CLI test keeps core's OUTPUT_VALUES in sync with OutputSetting.
- ownership::db::open_db/db_path drop their unused IdxConfig argument.
- One workspace version; shared dependency versions; no third-party
version changes in Cargo.lock. LICENSE is symlinked into each crate.
- flake: workspace version, new source paths, and a per-crate package
check (idx-cli is built from its tarball against packaged idx-core,
since idx-core is not on crates.io yet). CI cache key, release path
filter, and the golden whitespace-hook exclusion follow the new layout.
Parity: all 143 golden outputs match byte for byte without
regeneration; 157 core + 17 CLI unit tests (173 before plus the new
OUTPUT_VALUES sync test), 62 CLI tests pass. Live A/B against main:
16/16 stocks cases identical; ownership discover got IDX 403 on both
(exit 4 vs 1 is the phase 1 exit-code change).
