 #### Added
 
+- Added regression coverage for signed bit-length boundaries, deterministic
+  Intel/Motorola extraction, lookup failures, runtime validation, PGN, comments,
+  file formatting, metadata copying/lifetime, and TypeFactory behavior.
+- Added direct-handler and resolver tests for unsupported comments and ambiguous
+  `VAL_` references in manually constructed databases.
+- 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.
+- 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 `.user` settings stay
+  outside version control.
 - Basic `M` / `mN` multiplexing metadata in parsed, tree, and runtime definitions.
 - Deferred selector and overlap validation with source locations: one unsigned
   selector, representable branch values, and overlaps only between exclusive branches.

 #### Changed
 
+- Qt-dependent targets now require the installed Qt 6.8.2 through a shared qmake
+  version check; removed Qt 5 compatibility instructions. Core remains Qt-free.
+- Used explicit local types in the additional coverage and model tests. Functions
+  retain explicit return types, and runtime handler selection uses TypeFactory
+  without lambdas or extra factory layers for concrete objects.
+- Coverage documentation now describes the selected open GCC/LCOV toolchain.
 - Overlapping unconditional signals are now rejected during parsing.
 
 #### Fixed
 
+- Linked QtGui only in the optional model tests and used QGuiApplication with an
+  offscreen default, resolving the QAbstractItemModelTester invalid QPixmap
+  metatype warning without adding QtGui to the adapter library.
+- Accepted tabs after `CM_` by using the comment parser's keyword extraction
+  instead of requiring a literal-space prefix.
+- Removed test compiler warnings by using `QVERIFY_THROWS_EXCEPTION` and
+  explicitly discarding `nodiscard` return values in exception checks.
 - Reject duplicate frames by normalized CAN ID and frame type, including
   equivalent extended ID encodings, and duplicate signal names within a frame.
   Errors report the file path and line of the repeated definition. Standard and
