 Allocates the 9 ISV slots that drive the SP17 dueling-Q identifiability diagnostic chain. **Additive infrastructure only — no consumer wiring in this commit.** The Phase 1 mean-centering producer (atomic across `compute_expected_q` + `c51_loss` + `c51_grad` + `mag_concat_qdir`) lands in the next 4 commits per `feedback_no_partial_refactor`.
 
+**Fixup (post-quality-review):** `ADVANTAGE_CLIP_SAFETY_FACTOR` and `ADVANTAGE_CLIP_EMA_ALPHA` added to `sp17_dueling_slot_layout_locked` for assertion-coverage symmetry with the other named constants in the SP17 block. No code-path or contract change.

 ### Why SP17
 
 The codebase has separate V-head (`on_v_logits_buf`) and per-branch A-head (`on_b_logits_buf`) buffers, but combines them naively as `logit = v_row[z] + adv_a[z]` — no `A − mean_a A` subtraction. This is over-parameterization without identifiability: the optimizer is mathematically free to learn the degenerate `V ≈ Q(Flat), A ≈ Q(a) − Q(Flat)` decomposition, which IS the Q(Flat) attractor we have been fighting since SP11. The fix is small and surgical: insert mean-zero projection at 4 existing aggregation sites (Phase 1-3). PP.2 lays the ISV slot infrastructure for the diagnostics that observe whether the projection is doing real work.
