SEC XBRL `companyfacts` for Apple, tag `us-gaap:EarningsPerShareDiluted`
(same fetch as the sibling records in this batch) — the full set of `fp` values
observed across every entry for this tag is:
```
{None, "Q1", "Q2", "Q3", "FY"}
```
`"Q4"` **never appears**, confirmed across FY2023 and FY2024 entries explicitly
(and holds for the whole tag's 338-entry history, cross-checked via the
`companyconcept` endpoint for the same tag in the companion record). This matches
how 10-Q filings work: companies file three quarterly reports (Q1, Q2, Q3) and
then a single annual 10-K (`fp:"FY"`) that covers all four quarters plus
year-end items — there is no separate "fourth quarter" filing, so no `fp:"Q4"`
entry ever gets tagged. An agent that wants discrete Q4 figures must compute them
as `FY - (Q1+Q2+Q3)` using the single-quarter values (see the companion
cumulative-vs-discrete record for how to pick those out correctly) — filtering
`fp == "Q4"` returns nothing, silently, for every company that follows the
standard US 10-Q/10-K cadence. Worked example from this same fetch, Apple
FY2023 diluted EPS: `FY` total `6.13`; discrete-quarter values pulled from the
10-Qs (matched on `start` as in the companion cumulative-vs-discrete record)
give Q1 `1.88`, Q2 `1.52`, Q3 `1.26`. The implied Q4 is `6.13 - 1.88 - 1.52 -
1.26 = 1.47` — a real number `companyfacts` never states directly anywhere in
the array.
