//! Per-call `FieldResolver` construction for `test_method.rs`.
//!
//! Extracted out of `test_method.rs`, which sits at the file-size ratchet's frozen ceiling
//! (`tests/file_size_baseline.txt`) and may not grow. Behavior is otherwise unchanged from the
//! block this replaces, plus `with_ir_result_fields`/`with_anchored_optional_paths`: without
//! `with_ir_result_fields`, `FieldResolver`'s `ir_result_field_map` keeps its default `root_type:
//! None`, which makes `with_anchored_optional_paths` an unconditional no-op (it early-returns on
//! an unresolved root) regardless of what paths it is given. With both wired in, an
//! `Option<Vec<T>>` segment field reached through an array-projected path (e.g.
//! `entries[0].sections`) — which never matches `with_ir_fields`'s bare-name-only optional set
//! once the path crosses more than one segment — resolves correctly, and
//! `with_anchored_optional_paths` materializes that IR-anchored answer for this fixture's own
//! assertion paths into the lookup set the per-segment accessor renderer consults, mirroring
//! `presentation.rs`'s existing use of it.
