Answer "what changed in the core API between two core versions": symbols added, deprecated, removed, as ranked groups with counts. One symbol: lookup_core_symbol. Human write-ups: list_change_records. Every row of one bucket: flat=true with bucket, paged; every row of the whole diff: the result's bulk block (attach + sql for the published catalog, rows to disk not context). - Bounds inclusive; forms 11.2, 11.2.x, 11.2.0, 11, 11.x; same version twice = one minor; upgrading 11.2 → 11.4 means from=11.3. Buckets are independent. - Grouped (default): a head entry is a symbol group (grouped_by: change_record | name_prefix | singleton); head counts groups (≤ 5), count symbols, group_count groups; members ≤ 3 per group, highest usage first; group fields appear only when every member agrees. Rank: max_projects_using desc, then member_count magnitude, tier, count, key (ranked_by). head_covers_all_callers false → narrow with kind / min_projects_using or page with offset. - Flat (flat=true, bucket=added, deprecated, removed): rows by projects_using then fqn: fqn, kind, subsystem, stamp, projects_using, removal_in, removal_kind, replacement when the catalog names one, change_record_nids. count = public symbols in the bucket after filters; limit ≤ 100, next_offset absent on the last page. - Filters apply to every count. internal_excluded and test_theme_excluded are counted apart and left out; unplaceable_symbols have no minor in their stamp. - Usage = contrib development branches only, evidence rollup as of usage_evidence_built_at; 0 = no caller observed. - change_record_nids → get_change_record. removal_kind observed = gone, scheduled = promised and still present (say "scheduled for removal in 13.0").
