From 21052bc646905c8b11f2ec038bf715028eefcd6a Mon Sep 17 00:00:00 2001 From: Nick Tabeling Date: Mon, 13 Apr 2026 10:41:10 +0200 Subject: [PATCH] feat(DIS-152): mapped project paths (host:virtual) for agents Adds optional path_mappings to agent.yaml so host directories are transparently mapped to virtual paths in agent responses and CLAUDE.md. Sanitizer replaces host paths (longest first, both slash styles) before repoRoot/home substitutions. /new-agent accepts a host:virtual path option with Windows-safe splitting and fs.existsSync validation.
