docs(sp22): smoke scope — α ACTIVE β DEAD (B6 not landed)

Auditing the β reward shaping path revealed a producer gap:
- experience_kernels.cu:3614-3628 correctly computes r_aux_align from
  scale_β = isv_signals[537]
- But slot 537 has NO PRODUCER — SP11 controller still emits 6 components
  (N_COMPONENTS=6.0f), Phase B6 extension to 7 components hasn't landed
- → scale_β stays at alloc_zeros 0 → r_aux_align = 0 → β no-op

Current smoke validates α atom-shift mechanism ONLY. β remains dormant.

Updated verdict outcome table: WR-shift implies α works alone; WR-stable
with dist-shift implies α active but β needed (land B6 next, ~1-2hr).

Phase B6 scope documented (single-kernel edit to SP11 controller +
launcher update for N_COMPONENTS).

 **Diagnostic to add for next smoke** (deliberately deferred this run):
 - W[0..4] direct readback per epoch via mapped pinned [4] f32 + DtoD copy outside captured graph + HEALTH_DIAG log line. Would directly show Adam updates on W.

+#### Smoke scope clarification — α ACTIVE, β DEAD (2026-05-13)
+
+While preparing the verdict template, audited the β reward shaping path's producer chain. Finding:
+
+**β producer wired but UNFED**: `experience_kernels.cu:3614-3628` correctly computes `r_aux_align = scale_β × alignment × profit_pos` and writes to `reward_components_per_sample[out_off * 7 + 6]`. But `scale_β = isv_signals[SP22_AUX_ALIGN_SCALE_INDEX=537]` and slot 537 has NO PRODUCER — the SP11 `reward_subsystem_controller_kernel.cu` still treats `N_COMPONENTS = 6.0f` (popart/cf/trail/micro/opp_cost/bonus). Phase B6 (extend SP11 controller to 7 components with w_aux_align anchor) hasn't landed.
+
+**Net effect**: slot 537 stays at alloc_zeros sentinel 0 throughout training → `r_aux_align = 0` always → β reward shaping is a runtime no-op.
+
+**Implication for smoke verdict**: This smoke validates the **α atom-shift mechanism ONLY**. The β reward bonus (aux-aligned profitable trades earn extra reward) is dormant. If WR shifts off baseline, α is the cause; if it doesn't, the verdict is α alone is insufficient — β extension (Phase B6) becomes the next priority before investing in Phase D.
+
+**Phase B6 scope** (deferred): Extend `reward_subsystem_controller_kernel.cu`:
+1. `N_COMPONENTS: 6.0 → 7.0`.
+2. Read 7th component magnitude from `ISV[REWARD_AUX_ALIGN_EMA_INDEX=536]` (EMA already produced by reward_component_ema_kernel.cu's extended 0..7 loop — Phase B3 landed).
+3. Compute w_aux_align via the same blend formula as other components (winner × improving + diversifier × stagnant); anchor target = ~10% of total reward magnitude; bounds `[0.05, 2.0]`.
+4. Write to `ISV[SP22_AUX_ALIGN_SCALE_INDEX=537]`.
+
+Estimated ~1-2 hr engineering (single-kernel edit + launcher update if N_COMPONENTS is kernel-arg vs constant).
+
+**Updated outcome table** (replacing "Possible outcomes" in the verdict template):
+
+| Pattern | Interpretation | Next action |
+|---------|----------------|-------------|
+| WR ≥ 53% epoch 3, dist shifts | α atom-shift alone moves WR | Land B6 for β + Phase D for eval validation |
+| WR 50-53%, dist shifts | α partial effect | Tune W magnitudes OR land B6 to add β reward signal |
+| WR ~46%, dist shifts | Mechanism active but no WR translation | β probably necessary — land B6 next |
+| WR ~46%, no dist shift | α inactive (state_121 not flowing) | Investigate aux head + state_121 wiring |
+| Training collapse | Loss landscape unstable | Reduce W init magnitude or revert |
