# Latest COMPLETE calendar year. The current year's transactions are only
# partially reported (Land Registry lags ~2-3 months), so a sector's thin
# partial-year repeat-sale set produces wild index betas (e.g. +334% in a
# single sector). The index is SOLVED only on complete years (<= this) and
# forward-filled/trend-extrapolated to CURRENT_YEAR, so current-value
# projections follow the established trend instead of a partial-year spike.
