The information-table exhibit is **not** at a fixed path like `infotable.xml` — it is named by an arbitrary accession-local number (e.g. `56757.xml`), different for every filing, discoverable only by reading the accession's own `index.json`. 2. A single issuer/CUSIP is not guaranteed one row. A multi-manager filer (one 13F covering several affiliated advisers/sub-managers) reports the **same issuer multiple times**, once per manager holding it, cross- referenced only by an `` code resolved against a *separate* `otherManager2` list on the filing's own cover page (`primary_doc.xml`). ## Reproduce ``` GET https://www.sec.gov/Archives/edgar/data/1067983/000119312526352200/index.json directory.item[].name = [ "0001193125-26-352200-index-headers.html", "0001193125-26-352200-index.html", "0001193125-26-352200.txt", "56757.xml", <- the information table, numeric, unpredictable "primary_doc.xml" ] GET .../56757.xml -> 89 rows total, only 29 distinct values CUSIP 02005N100 (Ally Financial) alone appears 6 separate times, each with a different code combination (e.g. "4", "2,4,11", "4,5", "4,8,11") and a different share count — none of them the filer's full position alone. GET .../primary_doc.xml -> 14 entries, each a + (e.g. sequenceNumber 4 -> file number 28-554) resolving what each infoTable row's codes actually refer to. ``` ## Why it matters Counting `len(infoTable rows)` as "number of distinct positions held" over- counts by roughly 3x here (89 rows, 29 real issuers). Summing `` by CUSIP gives the filer's *aggregate* reported position correctly, but attributing it to a specific sub-adviser, or reconciling it against that sub-adviser's own separately-filed 13F, requires joining two different XML documents inside the same accession by a code (`otherManager`) that means nothing without the second file. None of this is discoverable from the information table alone.
