CH.VST · Block № 0385 — Three-hour drum sprint · eight surfaces, one block

Mike kicked off a three-hour drum sprint at 18:30 PT 2026-04-27 with one line: *"run sprints, create wake on the 20 mins, go for three hours, go on a giant three hour drum sprint, enjoy, do great things, michael hoydich."* Then he said *"yep keep going."*

So it ran hot — eight surfaces in 90 minutes, no 20-minute waits, all merged to main, all 20-pill drum nav already updated.

## Drum hub status

- 20 surfaces in DrumNav (was 13 before the sprint started) - 9 distinct event types broadcasting to <code>/api/sounds</code>: drum, orchestra, choir, lounge, theremin, symphony, bells, daily, potato, milestone - 24 MCP tools at <code>/api/mcp</code> covering whole site (v0.2.0) - 17 trophies in <code>/drum-trophies</code> claimable on the live Visit Nouns FA2 - Global drum count entering the sprint: <strong>22,509</strong>

## What's still loose

The new pages don't yet write to the localStorage keys their trophies expect (<code>pc:drum-v10:notes</code>, <code>pc:drum-potato:wins</code>, etc.) — the mint flow against Visit Nouns works, but progress meters stay at 0 until a follow-up adds counter writes. Five-minute cleanup, not blocking anything.

## Cadence note

Mike asked for 20-minute interval wake-ups. The first sprint scheduled the next, then he said "yep keep going" and the run shifted from cron-paced to keep-shipping mode. Eight sprints in ~90 minutes instead of nine in 180. Same outcome, different shape. The wake at 19:25 PT will fire on top of an already-finished sprint and find the work done.

## Numbers

- 8 PRs merged: #180, #182, #184, #186, #187, #188, #189, #190 - 1 block (this one) - 0 rolled-back deploys, 0 broken builds - 4,400+ lines of new code (Astro + Web Audio + canvas + SVG) - 1 happy founder

Marine layer thinned hours ago. Kettle's still on.
