Bundles 2 feedback rules and 16 pearls. Read-only; cites memory file by name on every finding.

Numeric literals used as anchor/target/cap/floor for adaptive behavior must derive from an ISV slot. Suggest a slot index and name. +2. **First-observation bootstrap on EMAs** (`pearl_first_observation_bootstrap.md`). EMA initialized to `0.0` (sentinel); first observation replaces directly, not blended. Flag any EMA initialized to a tuned constant. +3. **Wiener-α floor in non-stationary loops** (`pearl_wiener_alpha_floor_for_nonstationary.md`). Wiener-optimal α is MSE-optimal for stationary signals only. Where the target co-adapts (control loops), α must have a permanent floor (≥ 0.4 typical). +4. **Blend formulas use `max(real, floor)`** (`pearl_blend_formulas_must_have_permanent_floor.md`). Never `α·real + (1−α)·floor` — that deadlocks if real → 0. +5. **Controller ratios over magnitude-asymmetric signals z-score-normalized** (`pearl_zscore_normalization_for_magnitude_asymmetric_signals.md`, `pearl_controller_amplifies_dominant_magnitude_trap.md`). Ratios like `winner_weight = mag[c] / sum(mag)` over branches with intrinsically different magnitudes always elect the largest. Use `z[c] = mag[c] / sqrt(var[c])` instead. +6. **Per-branch C51/IQN/CQL/Ens budgets** (`pearl_per_branch_loss_budget.md`, `pearl_per_branch_c51_atom_span.md`, `pearl_per_branch_iqn_tau_schedule.md`, `pearl_per_branch_noisy_sigma.md`). Budgets and atom spans derived per-branch from per-branch flatness/skew/entropy-deficit; never shared across branches. +7. **Per-group Adam hyperparams** (`pearl_per_group_adam_hyperparams.md`). β₁/β₂/ε per param-group from grad direction-stability, not global. +8. **Kelly floors signal-driven, cross-fold-persistent** (`pearl_kelly_cap_signal_driven_floors.md`). Kelly floors derive from a cross-fold-persistent signal; sentinel-bootstrap is incompatible (don't reset at fold boundary). +9. **Trail-stop distance signal-driven** (`pearl_trail_stop_signal_driven.md`, `pearl_trail_fire_pre_vs_action_mag.md`). Per-direction trail distance signal-driven; trail filter on `pre_mag`, not `action_mag`. + +## Output format + +``` +[isv-discipline-auditor] reviewed: + +Findings: N +1.
