## Coverage
Two Nager.Date v3 behaviors not covered by this corpus's existing Nager.Date record (which documents unknown-country refusal shapes): the `LongWeekend` endpoint, and the `counties` subdivision field on `PublicHolidays` rows.

## Access
`GET https://date.nager.at/api/v3/LongWeekend/2026/US` — 200, JSON array of `{startDate, endDate, dayCount, needBridgeDay, bridgeDays[]}`. Observed 2026-10-05T11:49:52Z: first entry `{"startDate":"2026-01-01","endDate":"2026-01-04","dayCount":4,"needBridgeDay":true,"bridgeDays":["2026-01-02"]}` — New Year's Day (Thu) plus a flagged bridge day (Fri Jan 2) makes a 4-day weekend.
`GET https://date.nager.at/api/v3/PublicHolidays/2026/US` — 200, 17 rows. One row: `{"date":"2026-02-12","localName":"Lincoln's Birthday","counties":["US-CA","US-CT","US-IL","US-IN","US-KY","US-MI","US-NY","US-MO","US-OH"],"global":false,"types":["Observance"]}`.

## Auth
None (shared with the rest of Nager.Date v3; see existing corpus record for the base auth/rate-limit profile).

## Rate limits
Not separately observed for these two routes; no distinct limit documented beyond the base API.

## Freshness
Same release cadence as the base API (`/Version` reported `2.45.1` at probe time, shared across all routes).

## Known gaps
- **`counties` is misnamed**: every value observed is a full ISO 3166-2 **state/province-level** subdivision code (`US-CA`, `US-CT`, …), never an actual US county (no FIPS code, no "Cook County"-style name) — an agent expecting county-granularity data from a field literally called `counties` will get state-level data instead, for the one country (`US`) where "county" has a specific, different, more granular meaning.
- `counties` is **`null`**, not an empty array `[]`, on rows where `global: true` (e.g. Presidents Day) — absent-vs-null discipline matters if the consumer does `row.counties.length` without a null check.
- `needBridgeDay: true` only ever flags one observed holiday in the 2026 US year; most multi-day `LongWeekend` entries (e.g. the Feb 14–16 Presidents Day weekend) have `needBridgeDay: false` because the holiday already lands adjacent to the weekend with no gap to bridge.
