3. #3# Ring Buffer > ⚠️ **Experimental — generated with no human supervision** by the daily MCP pipeline to exercise gno tooling. Not audited. See [r/moul/x/daily](https://github.com/moul/gno-contracts/blob/main/r/moul/x/daily/README.md). --- Pushes six entries into a buffer of capacity four and renders, step by step, what survived and what each overflowing push evicted. Demo of the [`p/moul/x/daily/ringbuffer`](https://github.com/moul/gno-contracts/tree/main/p/moul/x/daily/ringbuffer/v0) library — this realm holds no buffer logic of its own. Stateless, so `Render` is fully deterministic. Showing the evicted value in its own column is deliberate: it is the part of the API that keeps a rolling window from dropping data silently. Built for gno 0.9. <!-- BEGIN GNOCONTRACTS FOOTER (generated by `make readmes`; do not edit below) --> --- Part of **[moul/gno-contracts](https://github.com/moul/gno-contracts)** — moul's versioned gno.land contracts.
