This is very similar to the design I arrived at.

You define when commands are dispatched, on a fixed or recurring schedule. The example is a bounded schedule that starts 20 seconds after boot, recurs every 3 seconds, and ends 10 seconds later.04 May 2026 12:03 +0000at://did:plc:af5ndzzxe7p5vbpmotcxmt6n/app.bsky.feed.post/3mkzmwninjk24https://bsky.app/profile/ismaelcelis.com/post/3mks5vpp2ss2pI've been working on three different Ruby libraries that solve (in my mind) different problems, but together make for my dream toolkit.

Goes well with SQLite for your own data.
