# `13FCONP` exists, is real, and a `form=='13F-HR'` filter silently skips it

**Claim:** Bridgewater Associates, LP (CIK 1350694) — a pure asset manager,
no public equity, no XBRL companyfacts — files `13F-HR`, `13F-HR/A`, and
also `13FCONP` ("combination report," used when part of a manager's
reportable holdings are filed jointly with/by another manager) and `N-PX`
(mandatory proxy-vote-disclosure filing since the SEC's 2023 rule), all
under the one CIK.

## Reproduce

```
GET https://data.sec.gov/submissions/CIK0001350694.json
  entityType: "other", name: "Bridgewater Associates, LP"
  distinct forms observed in filings.recent: {"N-PX","13FCONP","13F-HR","13F-HR/A"}

GET https://data.sec.gov/api/xbrl/companyfacts/CIK0001350694.json
  -> 404, application/xml, <Error><Code>NoSuchKey</Code>
     <Message>The specified key does not exist.</Message>
     <Key>api/xbrl/companyfacts/CIK0001350694.json</Key></Error>
```

The 404 itself is clean and consistent with the rest of this corpus's
findings about EDGAR's S3-shaped XBRL error pages — stated here as
confirmation, not a new claim. The new claim is `13FCONP` as a real,
present, easy-to-miss form value.

## Why it matters

Code written to answer "does this manager have 13F activity" by checking
`form == "13F-HR"` (or even `"13F" in form`, which *would* catch `13FCONP`
but not if someone instead checks `form.startswith("13F-")`) can silently
conclude a filer like Bridgewater has fewer or different 13F-type filings
than it actually does, because `13FCONP` doesn't share the `13F-HR` prefix
pattern most people reach for. It is also a trap for "find all 13F filers
with XBRL financials" — asset managers like this one will never have
companyfacts at all, by design, not by error.
