From 9f896878e0f85bebffd978463a4b9cdca2b6aa38 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Fri, 17 Apr 2026 08:30:12 +0200 Subject: [PATCH] =?UTF-8?q?feat:=20plan=20conviction=20scales=20reward=20?= =?UTF-8?q?=E2=80=94=20plan=20head=20learns=20from=20epoch=201?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Plan conviction (ISV-attention-driven) directly scales reward signal. Low conviction → dampened reward, high → amplified. No hardcoded constants. The plan head's forward path (h_s2 → ISV feature gate → Mamba2 temporal → plan MLP → conviction) is fully attention-driven. Learning flows: conviction → reward → Q-value → C51 loss → gradients. Plan learns planning, holding, strategic positioning throughout training.
