4 days	refactor: c/ -> usr/, compiled program blobs out of the source tree	user	1	-0/+0
	Userland sources live in usr/ (fits the Unix theme better than 'c'). SDCC output .bin blobs land in build/usr/ with the other build artifacts instead of littering the source dir; programs.asm INCBINs them from there. Byte-identical ROM.
6 days	jobs: background execution (&), non-blocking reap, spin demo	user	1	-0/+6
	- sys_reap: nohang reap of a finished zombie child (-> pid or 0). - shell: 'cmd &' launches in the background (prints [pid], no wait); reaps finished jobs at the prompt ([pid done]). Foreground now waits for its own child specifically (loops wait(), reporting bg completions meanwhile) so kill reports the right pid. - spin: a process that yields forever - a target for ps/kill. - verified: spin &; ps shows it; kill <pid> removes just that one; immortal init; self-finishing bg worker reaped with [pid done].
