Original CTE (CROSS JOIN LATERAL similarity на 1056 × 320 unmapped × top-3) завис на deploy таймауте (89M cost узнан через EXPLAIN database-expert worker). GIST trgm index — load-bearing для downstream queries, оставлен. Multi-feature INSERT (composite >= 0.75) уже частично применён inline 2026-05-17 (+13 мапingов: 129 → 142). Полный backfill будет в отдельной миграции 117 с pre-materialized temp tables для avoidance of full LATERAL scan.

-- Original version did INSERT through a 89M-cost CROSS JOIN LATERAL CTE that
|
|
-- timed out during deploy. Hotfix keeps только the GIST trgm index (this is
|
|
-- the load-bearing change for downstream queries — competitors fuzzy match,
|
|
-- objective_complex_mapping reverse matching).
|
|
--
|
|
-- Actual multi-feature INSERT was already done inline on 2026-05-17
|
|
-- (+13 mappings: 129 → 142). Remaining auto-accept candidates (~50-100 at
|
|
-- composite >= 0.75) will be applied via separate migration 117 after
|
|
-- the candidate query is pre-materialized to avoid full LATERAL scan.
