IDX stopped posting the monthly above-1% list as an announcement after
the 2026-05-29 report; June/July/August are only on the Data
Kepemilikan Saham page. `ownership discover` could not see them, and
IDX's Cloudflare now rejects curl_chrome142 on that page and on the
/Media/ XLSX files.
- remote: parse the page's Nuxt payload (Description/Prospectus pairs,
/ escapes), classify above-1% XLSX as supported and above-5% /
investor-type workbooks as unsupported, derive as_of_date from the
Indonesian description. Keep all above-1% entries, only the newest
of the other series. Merge with the announcement results.
- discover JSON gains `format` (xlsx|pdf) and `as_of_date`; page
entries use the as-of date as publish_date (the page shows none).
- import --url accepts .xlsx and downloads via the XLSX validator.
- curl_impersonate: run_owned_with_fallback tries several browser
profiles until the body validates (JSON / page payload / %PDF / PK);
IDX_CURL_IMPERSONATE_BIN still pins one.
- Tests: page fixture parsing, date parsing, payload validation, CLI
discover via a local page server; existing discover tests now point
IDX_OWNERSHIP_DATA_PAGE_URL at a closed port so no test hits IDX.
- Docs: ARCHITECTURE discovery section, AGENTS ownership inputs.
