/**
 * Narrow row-check read for the formula check-column polling gate.
 *
 * Reads ONLY three single-column bands of each requested User_Input tab —
 * the identity (business-key) column, the system row-id (anchor) column,
 * and the row-check formula column — in ONE paced `spreadsheets.get` with a
 * values-only mask. At the 300-row/3-data-column stub scale the gated read
 * is ~500 bytes/row (dominated by the formula text the provenance check
 * transfers) versus ~1.25 KB/row for the historical whole-table
 * metadata-preserving observation on the same fixtures — and the REAL
 * observation read carries far heavier per-cell format wrappers (the live
 * polling pass measured 2.95 MB before this gate). The polling side diffs
 * each returned check string against the value derived from canonical
 * SQLite state and escalates ONLY mismatched rows to a targeted full-field
 * snapshot read, so clean tabs never read a data column.
 *
 * Row mapping uses the visible identity column: it is the key inbound
 * inspection already resolves by (business key → entity → canonical state),
 * and unlike the system row-id column it exists for every system-written
 * AND human-typed row, keeping unknown/duplicate-identity detection exact.
 * The anchor band is read ALONGSIDE it so a clean poll can still prove the
 * system row-id cell was not deleted, duplicated, or moved off its row —
 * the provider reports the observed anchor value and the polling gate
 * escalates any anomaly to the whole-table observation (the authoritative
 * row-mapping/orphan-evidence path).
 *
 * Check evidence carries FORMULA PROVENANCE: a row's check string is
 * reported ONLY when the check cell still holds the EXACT system-generated
 * formula for that row. A human (or paste) that replaced the cell with a
 * literal equal to the current expected string, a foreign formula, or a
 * blank cell yields NO check evidence, so the gate can never be satisfied
 * by a stale copy and the row falls through to the full-field read.
 *
 * `status` is `checks_unavailable` when the tab has no provisioned check
 * column (the cell directly after the registered range does not carry the
 * `__hikoutei_row_check` header); callers then fall back to the historical
 * whole-table observation for that tab (mixed mode). A missing tab or a
 * malformed payload fails closed like every other provider read.
