heap-sql

Load before the first heap_executeQuery call, whichever skill is driving the analysis: the schema of a Jeffrey heap-dump index (class, instance, outbound_ref, class_instance_field, string_content, gc_root, dominator, retained_size) and the traps that return a wrong answer without an error — the string table is the name pool, not the String contents; outbound_ref.field_id counts the whole field layout; retained sizes need the current tree. Use for what the purpose-built heap tools do not answer: what objects' fields or strings hold across a class, a count or join they do not shape.
