Workstream E of the UK-migration master epic #665; child of #145. Rescoped 2026-08-19 per the vintage decision on #723: the migration now targets FRS 2024-25 directly, so this issue — formerly "FRS 2024-25 refresh after the 2023 swap" — inverts into the deferred option it displaced.
Scope (if ever activated)
Materialize the 2023 vintage from the microcosm pipeline, only if a concrete consumer needs it (e.g., historical comparability against populace_uk_2023 / the June release):
Where the old E11 scope went
Not on the August path. No owner. Unscheduled — close outright at decommission (WS-J) if no consumer has claimed it by then.
