-
-## Development approach
-
-A Test-Driven Development (TDD) workflow was followed throughout the project. Every component — from the lowest-level file reader to the GUI window — has a corresponding Google Test suite that was written before (or alongside) the production code. This ensures each module behaves correctly in isolation and makes regressions immediately visible.
-
-## SysfsRead class
-
-`SysfsReader` ([include/SysfsRead.hpp](include/SysfsRead.hpp), [src/core/SysfsRead.cxx](src/core/SysfsRead.cxx)) is the lowest-level component. It opens a sysfs-like file and translates its raw text content into a `SysfsStatus` enum:
-
-| File content             | Status              |
-|--------------------------|---------------------|
-| `"1"`                    | `Enabled`           |
-| `"error: temp too high"` | `ErrorTempTooHigh`  |
-| empty / whitespace-only  | `Empty`             |
-| file missing             | `Unreachable`       |
-| anything else            | `UnexpectedValue`   |
-
-The reader never throws on I/O errors; every outcome is expressed through the enum so callers can react without exception handling. A helper `trim_in_place` strips trailing whitespace and newlines before comparison.
-
-**Tests:** [tests/test_sysfs_read.cxx](tests/test_sysfs_read.cxx) — covers all five status branches by writing controlled content to a temporary file.
