SEC EDGAR `submissions.json` — the `filings.recent` window is capped,
and that cap can silently hide an amended filing.

```
GET https://data.sec.gov/submissions/CIK0000320193.json
```
HTTP 200, 163,743 bytes. `filings.recent.form` has exactly **1000** entries
(every parallel array under `filings.recent` has the same length), and the
**oldest** `filingDate` in that window is **2015-09-17**. Searching this window
for `form == "10-K/A"` returns **zero hits** — not because Apple never filed one,
but because its one (filed 2010-01-25) is older than the 1000-filing cutoff.
`filings.files` on the same response names where it actually is:
```json
[{"name":"CIK0000320193-submissions-001.json","filingCount":1264,
  "filingFrom":"1994-01-26","filingTo":"2015-09-15"}]
```
Fetching that shard directly confirms it:
```
GET https://data.sec.gov/submissions/CIK0000320193-submissions-001.json
```
HTTP 200, 204,857 bytes, a flat object (same per-field parallel-array shape as
`filings.recent`, but with no enclosing company-metadata wrapper) containing
**1264** filings including **two** `10-K/A` entries: `0001193125-10-012091`
(2010-01-25) and `0001047469-98-001822` (1998-01-23) — both invisible in the
main document's `filings.recent`. An agent that reads only `filings.recent` and
doesn't check `filings.files` for additional shards will conclude a long-lived
filer has no amended filings at all, when it simply has more than 1000 filings
and the amendment is older than the window.

How observed: 2026-10-08T05:05:22Z and 05:05:52Z UTC, curl GET, descriptive
User-Agent, 2 requests ~30s apart.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
