From 3f0c95a6821ca2784bd15697717684c6e576e717 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 11 Jun 2026 06:55:00 +0000 Subject: [PATCH] Incorporate real field case studies from the forensics portfolio MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The three anonymized client engagements that motivated this tool lived only on the external Vercel site, not in this repo.
