From a2da014936a05e426f018939544166e4d821b578 Mon Sep 17 00:00:00 2001 From: jedarden Date: Thu, 28 May 2026 02:12:35 -0400 Subject: [PATCH] docs(pdftract-2wdjp): add verification note for pages range flag The --pages RANGE CLI flag implementation was already complete in the codebase. All required functionality was present including: - Range parser in pages.rs with comprehensive tests - CLI integration in main.rs - HTTP serve support in serve.rs - MCP tools integration - PyO3 bindings in pdftract-py All acceptance criteria verified PASS.
