+## Low-baseline step-response — the hedonic asymmetry is EMERGENT, not primitive
+Ran ±impulse step-response on forseti (P0.239) and mimir (P0.615), up-headroom
+baselines. Series: `r29-pad-step-{forseti,mimir}-{pos,neg}.{json,csv}`.
+
+| agent (baseP) | POS impulse (max above baseline) | NEG impulse (isolated, neg−pos min) | decay retention/turn |
+|---|---:|---:|---:|
+| lofn (0.809)   | +0.000 (ceiling) | −0.175 | ~0.92 both signs |
+| mimir (0.615)  | +0.000 (decay-masked) | −0.175 | ~0.90 both signs |
+| forseti (0.239)| **+0.034** | **−0.034** | ~0.93 both signs |
+
+- **Positive impulse gain is small but real (~+0.03)** — visible above baseline only
+  when the baseline is low enough that decay-to-0 doesn't immediately mask it
+  (forseti shows +0.034; at higher baselines the same push is swamped by faster
+  absolute decay). The "positive can't move" symptom is **gain + decay competition**,
+  not only the positive_p_cap ceiling.
+- **Decay τ is symmetric across signs** (~0.9 retention/turn both) — no sign-dependent decay.
+- **Near a neutral baseline the raw gains are ~symmetric** (forseti +0.034 vs −0.034).
+  The large apparent asymmetry at high baselines is the **decay-to-neutral ×
+  positive-baseline interaction** — decay OPPOSES positive excursions and REINFORCES
+  negative ones when baseline > 0.
+
+**→ Calibration-fork answer (asymmetric decay vs ESM offset+bias):** the data supports
+**neither** an asymmetric-decay parameter (τ symmetric) **nor** a strong negative-bias
+primitive (raw gain ~symmetric near neutral). The Frijda "negatives loom larger" here is
+**emergent** from the neutral anchor + non-zero baselines, not a primitive to calibrate.
+The two real levers stay: **overall emotion→PAD gain** (too low, both signs) and the
+**neutral decay anchor** (which manufactures the apparent valence asymmetry for any
+persona whose trait baseline ≠ 0). Caveat: no base agent has a truly neutral baseline;
+forseti (0.239) is closest and shows near-symmetry — a definitive gain-symmetry isolation
+would need a neutral-baseline persona.
