+- [ ] **§6.7** SOTA-bar reproduction (§4.3): **definitively OPEN** — cannot be
+  closed transitively via the parity harness. Investigated; three concrete reasons:
+  1. **The native SOTA numbers aren't reproduced by any committed, runnable-today
+     test.** ADR-152 ~96% PCK@20 is a frozen result in
+     `benchmarks/wiflow-std/results/eval_retrained.json` that points at an **external
+     checkpoint** (`/home/ruvultra/wiflow-std-bench/upstream/test/best_pose_model.pth`,
+     not in the repo); the only relevant test `test_wiflow_std_parity.rs` is
+     `#![cfg(feature = "tch-backend")]` **and** `#[ignore]`d (needs gitignored
+     fixtures + LibTorch). ADR-027's `eval.rs::CrossDomainEvaluator` tests are pure
+     unit-math on hand-coded 2–3-element vectors, not dataset accuracy. ADR-024's
+     only accuracy-ish test asserts Spearman > 0.90 on **synthetic random**
+     embeddings (not real CSI, not the published > 0.95 bar); no room-ID / mAP /
+     anomaly-F1 test exists at all.
+  2. **Decisive structural blocker:** the bound AETHER surface is **structurally
+     untrained**. `EmbeddingExtractor`/`ProjectionHead` use random Xavier init
+     (`Linear::with_seed(…, 2024/2025)`, `embedding.rs:97–98`) and the binding
+     exposes **no weight-loading mechanism** (a grep of `aether.rs` for
+     `weight`/`load`/`checkpoint` returns nothing). So even if labeled data existed,
+     there is no way to load a real trained checkpoint into the binding — it cannot
+     validate mAP > 80% or any trained-model bar today.
+  3. **No committed labeled CSI input/pose-pair data exists** to reuse (MM-Fi/NTU-Fi
+     appear only as config-default subcarrier counts / external paths;
+     `benchmarks/wiflow-std/results/*.npy` are corruption masks + result summaries,
+     not labeled fixtures).
+  The §4.1 parity harness proves the **strongest claim available today** — the
+  Python binding is bit-identical to native Rust for the bound (untrained) surface.

+Closing it requires three steps, in dependency order:
+
+- **(a) Add trained-weight loading to the AETHER/pose bindings.** The binding needs
+  an API to accept a real checkpoint (e.g. an RVF/safetensors path) into
+  `EmbeddingExtractor`/`ProjectionHead`, replacing the current `with_seed` random
+  init. This is an **engineering task, tractable independent of data** and likely a
+  **near-term follow-up** — nothing can validate accuracy until it exists.
+- **(b) Commit or source a small labeled CSI fixture** (input CSI + ground-truth
+  pose/identity/room labels). Genuine **data-acquisition scope**.
+- **(c) Build a real eval harness** computing PCK / mAP / room-ID / anomaly-F1 /
+  Spearman on (a)+(b) and asserting the published bars.
+
+(a) is plausibly a single follow-up session; (b) and (c) are genuine research /
+data-acquisition scope beyond one session. This is a data/model-availability +
+missing-eval-infra problem, **not** a binding defect. Status stays **Proposed**
+until (a)–(c) land and §4.3 is run for real.
