make_presets.py documented a presets.generated test that was never registered, so a hand edit to CMakePresets.json could drift unseen; it is registered now, and the generator names its encoding and line ending so a regeneration on Windows writes the same file. The CMake comment's per-tier essay repeated each source's own header - and claimed naked stubs where all four use startup::entry - so it points there instead, and the flash size the boot base and the wrap-around both follow from is named once.

"""Regenerate CMakePresets.json - one uniform pipeline per chip.
|
|
|
|
The tiers reimplement the ATmega328P-only reference protocol, so that is the
|
|
whole chip list. It stays a generated file rather than a hand-written one
|
|
because the shape - configure, build, test, workflow, and a reflect pair
|
|
without tests - is the shape a second chip would need too.
|
|
|
|
Run from the repo root: tools/make_presets.py - or with --check, which
|
|
verifies the committed file matches this generator and edits nothing (the
|
|
ctest entry `presets.generated` runs that, so drift reds the gate).
