Rich archive entries (blog/video source material) for the day's shipped work:
the Douanier Audio-Intelligence API's first endpoints (#22/#36 scaffold+emotion
walking skeleton, #23 SQLite auth+CLI, #26 content-addressed cache with the
measured 5663x repeat speedup) and the Foundry sampling-classics demo sources.
Each entry stands alone for a cold reader — goal, what shipped (commit hashes),
non-obvious learnings + numbers.
