…erator + conformance tests The wire contract's executable spec, published at its canonical source (tests/fixtures/wire_contract/): Track-A shard (zip: y_pred (6,4) float32 + identifiers + byte-pinned §2 header), Hop-A manifest (E1: sidecar_sha256 null), Hop-B arrow shard (views_frames.io.arrow; sample column = the §4.5(b) ordering oracle), the §5.1 sidecar (9 pinned columns, NaN-GAUL row preserved), and the Hop-B run manifest (one per run, sidecar hash lives here per E1). Deterministic generator (scripts/build_wire_fixture.py): injected provenance literals (§10.2), fixed seed, pinned zip timestamps — rebuild reproduces the bytes (verified). Root hash pinned in the fixture README + ADR-013 post-adoption record: b1f3878df9ef74b25dce53a070e1711db39dfdf1c6ca3e1f5a716875ceb32f44. Consumers vendor + hash-test per §10.1; the committed bytes are canonical. Deliberate pins: values row 0 draw-degenerate (§6 per-row rule), lr_ged_sb vocabulary (§7a), header parity across both envelopes tested byte-level. 7 conformance tests; ruff clean; 152 passed, 43 xfailed.

Build leg 2e — the contract's executable spec, at its canonical source (§10.1). Both other repos build against these bytes: pipeline-core's vendored fixture-parity test (flagged on closed #269) and faoapi epic S8.
