pub const WRITE_BATCH: usize = 19;Expand description
How many aliased writes one request of a copy’s board field values and blocked-by edges
carries: graphql::WRITE_FIELD_VALUES, graphql::ADD_BLOCKED_BYS and, for a request
holding both kinds, graphql::WRITE_FIELDS_AND_EDGES.
Nineteen is the most aliases the feasibility spike
(board-copy-gaps-2026-10-24-spike-feasibility-report) sent in one mutation request and
saw GitHub price at the one point every mutation request costs; no larger request was
established, so a copy holding more is split.
