From 85481c7f4ee046ee2ce06d508115ec16b3603d68 Mon Sep 17 00:00:00 2001 From: zbigniew sobiecki Date: Thu, 19 Mar 2026 10:41:37 +0100 Subject: [PATCH] docs: add architecture diagram with factual corrections and visual polish MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rewrite docs/architecture.d2 to accurately reflect the codebase topology: - Nest worker manager and cancel listener inside the Router process - Show both BullMQ queues (cascade-jobs, cascade-dashboard-jobs) - Rename "api" to "Dashboard API (:3001)" with port number - Label DB as PostgreSQL, show Redis as explicit infrastructure - Add LLM Providers (Anthropic, OpenAI, OpenRouter) as external dependency - Show cancel flow (Dashboard → Redis pub/sub → Router → kill container) - Use dashed borders for ephemeral Docker worker containers - Consolidate worker1/2/N into a single representative worker box Render to SVG and embed in README.md under the Architecture section.
