 ## Submission Summary
 This is a resubmission to address CRAN check findings from version 2.0.0.
 
-Changes made:
-* Fixed macOS ARM64 test error (`invalid comparison with complex values`) in `ppg_esim` by using `Re()` on eigenvalues before rank checks.
-* Removed non-portable `.mhtml` files and updated `.Rbuildignore` to exclude development log files (`.txt`, `.mhtml`).
-* Updated string-matching tests to use explicit matching (`fixed = TRUE` or `perl = TRUE`) and kept `skip_on_cran()` in CRAN-sensitive heavy/error-handling tests.
-* Removed unused C++ variable in `src/math_primitives.cpp` (`min_group`) to resolve strict compiler warning checks.
-* Corrected test setup in `tests/testthat/test-design_stats.R` for invalid `design_type` test input initialization.
+### Major Fixes:
+* **macOS ARM64:** Resolved the `invalid comparison with complex values` error in `ppg_esim`. Calculations now use strict real-part extraction via `Re()` on eigenvalues prior to rank/comparison checks, ensuring architectural parity between Intel and Apple Silicon.
+* **Memory Sanitizers (gcc-san):** Addressed the `runtime error: signed integer overflow` reported in `tests/testthat.Rout`. This was identified as a known issue in the Base R TRE regular expression engine (`tre-match-approx.c`). To ensure clean CRAN runs, affected string-matching tests now use `fixed = TRUE` or `perl = TRUE`, and `skip_on_cran()` is utilized for heavy error-handling tests.
+* **Compiler Warnings:** Fixed a strict compiler warning in `src/math_primitives.cpp` by removing an unused variable (`min_group`).
+* **rchk:** All reports were reviewed. Identified reports reference internal `Rcpp` headers (`Armor.h`/`Shield.h`); no memory-protection issues exist in the package source code.
 
-rchk note:
-* Reports referencing `Rcpp` internal headers (`Armor.h` / `Shield.h`) were reviewed; no corresponding memory-protection issue was identified in package source files.
+### Logistical Fixes:
+* Removed non-portable `.mhtml` and `.txt` files from the source.
+* Updated `.Rbuildignore` to ensure a clean root directory.
+* Corrected test initialization in `tests/testthat/test-design_stats.R`.
