+
+### Smoke result (2026-05-12) — H6 FALSIFIED
+
+Workflow `train-cr9hl` dispatched on `sp20-aux-h-fixed` @ `7fc979934`:
+
+```
+argo submit  dqn --baseline --branch sp20-aux-h-fixed \
+  --epochs 3 --gpu-pool ci-training-l40s
+```
+
+Terminated at `epoch=1` end after 36m58s wall-clock (saved ~1h35m of L40S
+time per `feedback_kill_runs_on_anomaly_quickly`).
+
+**Verification chain (pre-smoke gates, all clean)**
+
+- `CAPTURE_PHASE_AUX_DONE` + `CAPTURE_PHASE_POST_AUX_DONE` — the new
+  `aux_softmax_to_per_env_kernel` launched inside the captured forward
+  graph without breaking graph recording. This was the highest-risk
+  failure mode (per `pearl_no_host_branches_in_captured_graph` host
+  branches would have broken capture); the kernel is pure per-thread
+  gather with no host branches and capture worked end-to-end.
+- 13 child graphs captured + parent composed; step 0 = 540ms (capture),
+  steps 1-50 replaying at 0-486ms (graph replay nominal).
+- No CUDA errors, no panics, no OOM through epoch 1.
+- `fill_f32` cold-start + (one-shot, since we only ran 1 epoch) seemed
+  to leave the buffer correctly initialized — no init-related failures.
+
+**Epoch 1 outcome (cycle 1 verdict)**
+
+```
+GPU trades=489959 wins=245998 losses=243961 PF=0.947
+```
+
+Win Rate = 245998 / 489959 = **50.21%**
+
+This sits **squarely in the runbook's pre-declared falsification band**
+(50.1–50.2%) — same plateau observed across all v5–v11 baselines pre-H6.
+
+**Aux head telemetry at HEALTH_DIAG[0]**
+
+```
+aux_dir_acc target=0.5500 short=0.2798 long=0.2801 pred_tanh=0.6626
+aux [next_bar_mse=5.686e-1 regime_ce=3.044e0 w=1.175]
+aux_b1_diag dir_acc_short=0.2798 dir_acc_long=0.2801 n_down=0 n_up=0 n_skip=0 mask_frac=0.0000
+sp20_isv [wr_ema=0.3911 hold_pct_ema=0.2004 hold_reward_ema=-0.2044]
+```
+
+The `pred_tanh=0.6626` (batch mean of `softmax[1] - softmax[0]`) shows
+the aux head was producing strongly directional predictions (biased
+"up") at cycle 0. So the **signal content was there** — the bridge
+was conducting non-trivial directional data. The policy just couldn't
+turn that into a directional Q-gap.
+
+`dir_acc_short/long = 0.28` with `n_up = n_down = n_skip = 0` at
+HEALTH_DIAG[0] is the cold-start sentinel-decay path (labels hadn't
+flowed yet at the moment HEALTH_DIAG fired); the eventual epoch-1
+trade-stats `WR = 50.21%` is the post-warmup ground truth.
+
+**Other corroborating signals**
+
+`LOW EXPOSURE DIVERSITY at epoch 1` warnings:
+```
+S_Small 3.8% (309619/8192000)
+H_Half  0.4% (33713/8192000)
+H_Full  0.8% (63340/8192000)
+L_Small 4.2% (341432/8192000)
+F_Half  1.7% (141220/8192000)
+F_Full  3.5% (283700/8192000)
+```
+
+The policy is concentrating on a few branches. This is the same pattern
+documented in `project_dueling_va_unidentifiable` — Q(Flat) attractor,
+V parking at Q(Flat), A reducing to deltas. When the action distribution
+is degenerate, state slot 121 has no leverage to differentiate Q-values
+*regardless* of its content. Implies the bottleneck is upstream of the
+state-bridge wire.
+
+**What the smoke ruled in vs. out**
+
+| Hypothesis | Status |
+|---|---|
+| H6 wiring crashes capture / breaks training | Ruled out (clean capture, clean run) |
+| Aux head produces zero-information predictions | Ruled out (`pred_tanh = 0.66`, strongly directional) |
+| Aux→state bridge moves policy WR off 50% in ≤3 epochs | Ruled out (50.21% at epoch 1) |
+| Policy can't gradient-couple to a new directional state dim under current rewards | **Supported** (consistent with reward-density + V/A pathology hypotheses) |
+
+**Phase 1 close-out**
+
+- Phase 1 H6 wiring **stays merged** per `feedback_no_functionality_removal`.
+  The state slot is allocated, the buffer is initialized to a neutral
+  sentinel via pure-GPU fill, and the copy kernel runs inside captured
+  graphs. None of this is harmful; if H3 or a V/A fix lands and the
+  policy starts gradient-coupling to directional features, slot 121 is
+  already wired.
+- A2 (eval-side aux integration) is **deferred indefinitely** — A3 NULL
+  fallback works correctly for the eval and there is no production
+  justification to add an eval-side aux trunk forward until training-side
+  evidence shows the bridge is doing useful work.
+
+**Next-investigation framing**
+
+The smoke supports the "policy can't gradient-couple under current
+rewards" branch. Two upstream candidates:
+
+1. **H3 — reward density alignment** (per
+   `pearl_event_driven_reward_density_alignment`): event-driven
+   objective (trade close) with per-step shaping creates exposure-positive
+   bias. Per-step micro/opp_cost rewards dominate sparse directional
+   alpha. The cycle-1 telemetry has `hold_reward_ema = -0.2044`,
+   `hold_pct_ema = 0.2004` against `target_hold_pct = 0.1151` — the
+   policy is holding ~74% above target and the hold-reward is strongly
+   negative; cost dominance pattern.
+
+2. **V/A unidentifiability** (per `project_dueling_va_unidentifiable`):
+   structural; the LOW EXPOSURE DIVERSITY pattern at cycle 1 is a direct
+   tell. The dueling architecture lets the optimizer park V at Q(Flat),
+   degenerating the action distribution regardless of state content.
+
+**Sequencing**: H3 first, V/A second. Reasoning: if rewards aren't
+producing directional gradient pressure, then "fixing" V/A is optimizing
+the same degenerate objective with a different head shape. Heal the
+gradient signal upstream, then re-test whether V/A still pathologizes
+with healthy rewards.
+
+If H3 lands and the WR moves but action-space stays narrow, V/A is
+binding and gets fixed next. If H3 doesn't move WR either, V/A goes
+first and we re-test in combination.
