 <li>Added regression coverage for signed bit-length boundaries, deterministic Intel/Motorola extraction, lookup failures, runtime validation, PGN, comments, file formatting, metadata copying/lifetime, and <a class="el" href="classTypeFactory.html" title="Registry-based factory for creating objects by runtime identifier.">TypeFactory</a> behavior.</li>
 <li>Added direct-handler and resolver tests for unsupported comments and ambiguous <code>VAL_</code> references in manually constructed databases.</li>
 <li>Documented GCC/gcov/LCOV instrumentation, Qt Creator setup, and HTML reports. Coverage after the added tests: 98.4% of lines and 71.4% of branches with GCC 14.2 and Qt 6.8.2, including the standalone tree test.</li>
+<li>Added a reusable post-build coverage report script and step-by-step Qt Creator configurations for model tests, strict warning checks, coverage, core-only, standalone tree tests, and the demo. Machine-specific <code>.user</code> settings stay outside version control.</li>
 <li>Basic <code>M</code> / <code>mN</code> multiplexing metadata in parsed, tree, and runtime definitions.</li>
 <li>Deferred selector and overlap validation with source locations: one unsigned selector, representable branch values, and overlaps only between exclusive branches.</li>
 <li>Selector-first decoding using exact raw values, preserving definition order and unconditional signals. Explicit statuses distinguish inactive branches, missing selector data, insufficient payloads, and malformed runtime metadata.</li>
