Spend longer whenever you need.</p><p>A bootable kernel needs a chosen target, boot protocol, linker layout, freestanding runtime, exception entry, memory management, and drivers. The current repository does not supply all of these. Choose one small contribution: replace a stub with a tested host model, add a boundary test, or document an interface. Later milestones must boot in an emulator and prove each subsystem through observations.</p><p><strong>Practice and evidence:</strong> Create a Forge branch, commit the change and test evidence, and open a pull request. Your report must distinguish a host test from a boot test. A track certificate records these lesson checks; it is not a claim that a production OS is complete.</p><h3>Practice and evidence</h3><p>Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.</p><p><a href="https://git.agilaos.com/matt/open_kernel">Language reference: git.agilaos.com</a></p><p><a href="https://git.agilaos.com/matt/agila_open_tool">Language reference: git.agilaos.com</a></p></html>
