From 453b9574c36ee1cfe0b079d556f28408c2e4aabe Mon Sep 17 00:00:00 2001 From: Ammar Date: Tue, 17 Feb 2026 14:01:15 -0600 Subject: [PATCH 01/28] =?UTF-8?q?=F0=9F=A4=96=20feat:=20add=20end-to-end?= =?UTF-8?q?=20actor-critic=20mode=20loop?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement actor-critic mode across command parsing, send options, backend stream orchestration, and UI rendering. - Add /critic toggle command and workspace-scoped critic prompt persistence. - Add backend actor↔critic automatic turn loop with strict /done termination and critic-only tool disable policy. - Persist actor/critic message source metadata and transform request history for critic role-flip + actor feedback. - Render critic reasoning/assistant output with dedicated source badges and styling. - Expand mock router/player plumbing and add comprehensive UI coverage for looping, /done semantics, context recovery, and interrupt behavior.
