Tasks 1-2 of the bench-harness plan (refs #251): the new dev-only workspace bin crate with the report-only comparison core (BaselineDoc serde, per-metric relative drift, 10% NOTICE threshold, fingerprint-equality exit code) and the deterministic synthetic inputs (seeded LCG price walk, the proven 48-byte Delphi-record M1 zip archive writer, self-deleting scratch dirs). The archive writer is deliberately a third copy of the test-fixture packer (aura-cli tests / aura-ingest each carry one), byte-compatible by construction and pinned here by a round-trip test through the real ingest reader. The binary refuses debug builds (exit 2) — wall-clock numbers from a debug profile measure the profile, not the code — pinned by an E2E spawn test. Temporary #![allow(dead_code)] markers cover the not-yet-wired core until the CLI glue lands; the surfaces and driver follow.
