SEC XBRL `companyfacts` for Apple (`CIK0000320193`), tag
`us-gaap:RevenueFromContractWithCustomerExcludingAssessedTax`, unit `USD`.

```
GET https://data.sec.gov/api/xbrl/companyfacts/CIK0000320193.json
```
HTTP 200, 3,789,099 bytes. This single tag's `units.USD` array has **117
entries**, but only **71 distinct `(start,end)` period pairs** — 46 of them
are duplicated, because every filing re-reports the prior comparative period
alongside its own new period. Example, the exact same reported value appears
twice for the period 2017-10-01 to 2017-12-30 (val `88293000000`):
```json
{"start":"2017-10-01","end":"2017-12-30","val":88293000000,
 "accn":"0000320193-19-000010","fy":2019,"fp":"Q1","form":"10-Q","filed":"2019-01-30"}
{"start":"2017-10-01","end":"2017-12-30","val":88293000000,
 "accn":"0000320193-19-000119","fy":2019,"fp":"FY","form":"10-K","filed":"2019-10-31","frame":"CY2017Q4"}
```
Two traps for naive dedupe: (1) `fy`/`fp` describe **which filing the number came
from**, not the period the number covers — `fp:"Q1"` here does not mean the value
IS a Q1 figure, the value covers calendar 2017-Q4, reported as a comparative in a
later Q1 10-Q. (2) The `frame` key (the calendar-bucket label, e.g. `CY2017Q4`)
is present on the 10-K's copy of this datapoint but **absent** on the 10-Q's
copy of the identical number — `frame` presence is not a reliable "this is the
canonical/latest entry" signal, it just reflects whether that particular filing's
XBRL tagging happened to register with the SEC's calendar-frame index.
Deduplicating this array correctly requires grouping by `(start,end)` and then
choosing by `filed` date (latest), not by presence of `frame` or by `fp`.
