/**
 * Ranking weights of the DeD building search.
 *
 * There are two layers and they are deliberately separate:
 *
 * 1. The tsvector weight classes (A/B/C/D) are baked into mv_ded_building_search by the migration -
 *    A = name + designation + registration unit (evidenční jednotka) name, B = main address,
 *    C = secondary addresses, D = identifiers + registration unit code. Changing those requires a
 *    migration and a refresh. tsRank below is the weight array ts_rank_cd applies to them, in
 *    Postgres order {D, C, B, A}.
 * 2. Everything else is applied at query time and can be retuned without a release.

 * Reasoning for the defaults:
 * - tsRank {0.05, 0.2, 0.5, 1.0}: the name is the most distinctive field, the main address is worth
 *   half of it so a name hit outranks an address hit, secondary addresses stay at the Postgres
 *   default, and identifiers sit near zero because identifier queries are answered by the exact
 *   tier - class D only helps partially typed identifiers surface at all.
 * - ftsRank 0.45: the primary relevance signal, but under half so it cannot alone dominate.
 * - nameTrigram 0.30: typing Czech without diacritics is the normal case, not an error case.
 * - addressTrigram 0.15: half of the name weight, mirroring the A/B ratio of layer 1.
 * - prefixBonus 0.30: in a suggest box, what was typed at the start is strong evidence of intent.
 * - geometryBonus / activePointsBonus 0.05: tie-breaks only, never enough to reorder real relevance.
 * - missingBuildingPenalty 0.80: mapping-only GIDs must stay findable but rank below described
 *   buildings; multiplicative so it scales with confidence.
