 * Conflict target for upserting into `oee_records` (KAR-704 O8).
 *
 * After migration #63 / KAR-698 G2 the row is unique per
 * `(project_id, line_name, calendar_week, year)` via the constraint
 * `oee_records_project_line_kw_year_key` (the old global
 * `(line_name, calendar_week, year)` key was dropped).
 *
 * Every write path — the web OEE calculator and the v1 API — MUST upsert on
 * exactly this target so that iOS and web writes for the same line/week stay
 * idempotent instead of producing duplicates (or a 23505 constraint error).
