The person-week grid that [add_lmed_v20230509()] and [add_lmed_v20250909()] write their exposure columns into. One row per person per ISO week, with no payload columns: the entry points add every derived column themselves.
Format
A [data.table::data.table] with 5616 rows (18 persons x 312 ISO weeks) and 2 columns:
- id
integer. Person identifier, 1 to 18, matching the identifier column of [fake_lmed_2023] and [fake_lmed_2026].
- isoyearweek
character. ISO year and week as `"YYYY-WW"`, from `"2015-02"` to `"2020-52"`, sorting correctly as a string.
Source
Synthetic. Generated by `dev/generate_fake_lmed.R` with `set.seed(42)`, from the same weekly grid as [fake_lmed_2023] and [fake_lmed_2026]. The grid deliberately spans 312 ISO weeks (2015-W02 to 2020-W52, six ISO years) so that the 156-week minimum-duration rule is reachable within the fixture.
