// Fixture: MPE_X_SEARCH, a 1000-row demo table built by the mock data builder
// (sas/mocks/sasjs/services/admin/makedata.js).  It is deterministic, so every
// count below can be derived by hand:
//   - 1000 rows, PK 1001-2000, columns in demo order: PRIMARY_KEY_FIELD,
//     SITE_NAME, VESSEL, SAMPLE_COUNT, DEPTH_M, SPECIES, CRUISE_DATE,
//     EXPEDITION_ID, NOTES
//   - 300 rows have a site name containing "Trench" (case sensitive, so
//     "trench" matches nothing)
//   - 280 rows contain "Halcyon": the site Halcyon Trench (100 rows) plus the
//     vessel RV Halcyon (200 rows) less the 20 rows that are both
//   - 3 rows carry "siphonophore" in the middle of their NOTES text, in the
//     sites Oceanus Rise, Nereid Trench and Halcyon Trench
//   - 100 rows observed Vampire squid (species is picked by (site+vessel)%10)
//   - 100 rows are at Oceanus Rise (site is picked by (n%50)/5)
//   - 9 rows have an expedition id starting EXP-000 (EXP-0001..EXP-0009)
//   - the first row (PK 1001) is the only one with EXPEDITION_ID EXP-0001
//   - 12 rows were sounded at exactly 1000m (DEPTH_M = 1000 + (n%90)*37)
//   - 2 rows have SAMPLE_COUNT 4210 (the only numeric value that is not a
//     primary key, a depth or a date)
//   - PK 2000 is the last row of the table
//   - 200 rows were surveyed by RV Halcyon, 60 of them at a Trench site
