Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@xyo-network/xl1-statement-graph-engine-actor

Actor-runtime and local sequencing adapters for @xyo-network/xl1-statement-graph-engine.

The extracted actor-side composition now provides two real local clock backings, a serialized replay controller, a canonical local runner, and locator-backed lifecycle hosts:

  • MemorySequenceClock keeps one totally ordered, instantly finalized log in process.
  • ArchivistSequenceClock persists a tamper-evident chain of transaction/slot pairs in any XYO ReadWriteArchivist. Every transaction envelope pins the Statement Graph fold version; missing or older markers fail loudly and require a deliberate log rebuild rather than silently replaying old state.
  • StatementGraphReplayController traverses finalized positions, verifies bodies through the canonical SDK, applies them through the neutral engine, and exposes a backing-neutral canonical viewer.
  • LocalStatementGraphRunner shares the SDK's prepared-batch invariants, verifies body retention before append, and materializes each appended batch synchronously through the replay controller. Its dataHash-addressed local backing rejects Claim events carrying $... client metadata; those require an XL1 same-block root-hash carrier.
  • StatementGraphViewerActor and StatementGraphRunnerActor resolve direct clock/body-store seams or derive both from a caller-bound archivist, replay on start, prove readiness, and register the canonical viewer/runner services.

The trusted, unsigned Bound Witness envelope now includes statement_fold_version. This is an intentional fold-4 persistence break: pre-fold-4 transaction identities change, and old durable logs fail with an explicit rebuild error instead of silently replaying subject-less Claims under new semantics. The host keeps the xl1.statement.* locator monikers, while Edge-specific schemas and vocabulary remain outside this package.
