# Size Preset Validation

- Commit: `1fe189eb`
- Date: 2026-05-21T16:09:03.950909
- Validation target: `APP=HelloSizeAnalysis APP_SUB=preset_validation PORT=qemu CPU_ARCH=cortex-m0plus`
- Validation method: rewrite the app-local preset override header from each template, then build the qemu target and collect ELF section sizes.
- Purpose: verify that preset template files themselves are syntactically valid and can be used as direct app-local config bodies.
