// TestTransformChunkFields_IngestionShape is the T0 unit-tier read-back
// baseline for the Infinity engine (issue #17371). Unlike Elasticsearch, which
// stores the suffixed field names verbatim, Infinity reverse-maps the
// ingestion-emitted names to its own base names inside transformChunkFields.
// This test calls that transform directly (the engine requires a live Infinity
// instance, so it cannot be exercised via httptest) and asserts the mapping
// stays stable. It guards T2: when the suffixing is moved out of ingestion into
// the engine write boundary, transformChunkFields must keep producing the same
// base-name document.
//
// The input mirrors the shape produced by indexdoc.ProcessChunksForPipeline
// after T1 (kb_id is a plain string).
