Overview

One call-site’s calldata record. Mirrors the on-disk shape at research/cruby/ibf-format.md §4.1 “call info (ci) entries”: per-cd: mid_idx, flag, argc, kwlen, kw_indices.

mid_idx and kw_indices are OBJECT-TABLE indices (ID refs), not resolved symbols — that mirrors how other operands are stored and preserves byte-identical round-trip. Resolution to Symbol happens via the passed object table (see IR::CallData#mid_symbol).
