Standup digest

Reads yesterday’s commits, stamps the date from a builtin, and writes your three bullets.

Every morning: the note is already written. You glance, you tweak one word, you go. · conformance-gated in nika-spec ↗ · re-proven at every push

The whole file

4 tasks · 3 waves · the plan falls out of the bindings, nothing is scheduled by hand.
