SEC Form 13F-HR: the infoTable <value> field's unit changed by exactly 1000x at the 2023 reporting-modernization rule change (thousands of dollars before, whole dollars after), with no unit indicator anywhere in the XML to tell the two eras apart

# 13F `<value>` is in thousands pre-2023, whole dollars after — same schema, no flag

**Claim:** The Form 13F information-table XML schema is unchanged across the
2023 reporting-modernization rule (effective for information tables filed
after 2023-01-03-ish quarters): the same `<value>` element name, same numeric
type, same position in the row — but its **unit scale changed by exactly
1000x**, and nothing in the document (no attribute, no units field, no
version marker visible without checking the accession date) says so.

## Reproduce

Berkshire Hathaway (CIK 1067983), Apple Inc. position, identical share count
(692,000 shares) across two different 13F-HR filings, same `sshPrnamt`:

```
GET https://www.sec.gov/Archives/edgar/data/1067983/000095012322009450/15796.xml
  (13F-HR filed 2022-08-15, period 2022-06-30)
  <nameOfIssuer>APPLE INC</nameOfIssuer> <cusip>037833100</cusip>
  <value>94610</value>  <sshPrnamt>692000</sshPrnamt>

GET https://www.sec.gov/Archives/edgar/data/1067983/000119312526352200/56757.xml
  (13F-HR filed 2026-08-14, period 2026-06-30)
  <nameOfIssuer>APPLE INC</nameOfIssuer> <cusip>037833100</cusip>
  <value>200237120</value>  <sshPrnamt>692000</sshPrnamt>
```

94,610 **thousand** dollars ($94.61M, pre-rule reporting) vs. 200,237,120
**whole** dollars ($200.24M, current reporting) for a materially comparable
position — the magnitude gap is explained entirely by the unit-scale change,
not a 2122x price move.

## Why it matters

Any code written against pre-2023 13F data (when `value` meant thousands —
the SEC's own cover-page instructions for the schema haven't needed updating
in the XML itself) that is pointed at a current filing will under-report
dollar exposure by 1000x, or code calibrated against current filings will
over-report pre-2023 history by 1000x, with zero machine-readable signal in
either document to catch the mistake — only the filing date (or period of
report) distinguishes the two eras, and that date must be compared against
the rule's effective date out-of-band.

How observed: 2026-10-13T18:26:19Z (submissions list), 18:27:39Z (current
infotable), 18:28:03Z–18:28:07Z (2022 filing's index + infotable), curl 8,

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.
