+# `omath::SectionScanResult` — File-based pattern scan result
+
+> Header: `omath/utility/section_scan_result.hpp`
+> Namespace: `omath`
+> Depends on: `<cstddef>`, `<cstdint>`
+
+`SectionScanResult` is the return type for file-based pattern scans across all binary formats (PE, ELF, Mach-O). It carries the section's virtual and raw base addresses together with the offset to the matched pattern.
+
+---
+
+## API
+
+```cpp
+namespace omath {
+
+struct SectionScanResult final {
+    std::uintptr_t virtual_base_addr;  // virtual address base of the scanned section
+    std::uintptr_t raw_base_addr;      // file offset of the section start
+    std::ptrdiff_t target_offset;      // offset from section base to the first matched byte
+};
+
+} // namespace omath
+```
+
+---
+
+## Computing addresses from a result
+
+```cpp
+omath::SectionScanResult res = /* ... */;
+
+// Virtual address of the match (as if the binary were loaded at its preferred base)
+auto va_hit  = res.virtual_base_addr + res.target_offset;
+
+// Raw file offset of the match
+auto raw_hit = res.raw_base_addr + res.target_offset;
+```
+
+---
+
+## Notes
+
+* `virtual_base_addr` is computed from the section header (RVA for PE, `sh_addr` for ELF, `addr` for Mach-O).
+* `raw_base_addr` is the file offset where the section data begins on disk.
+* `target_offset` is always relative to the section base — add it to either address to locate the match.
