Everything it does, and what's next.

Every feature in the release this site pins, tagged with the release it arrived in. When a release adds a feature, this site has to describe it before it can build. Every release, and what it printed

• Scan since 0.3.0

  Point it at your site or docs: it finds every value you state more than one way, and where the copies disagree.

  wherefore scan

• Start a corpus since 0.1.0

  One command starts a repository; the skill walks your agent through the first fact.

  wherefore init

• The gate since 0.1.0

  On every push, each file must be built from the source, written by a person for a stated reason, or a capture stamped with what it shows. Anything else stops the change, and says why.

  wherefore gate

• The build since 0.1.0

  Every asset rebuilt from the source, the same way every time, so you see exactly what a change moves.

  wherefore build

• What builds what since 0.7.0

  A page for every repository: each file, how it is made, and what changes when a source does. One command draws it, and changes nothing.

  wherefore graph

• Proofs since 0.1.0

  No check is trusted until it has failed: each proof plants the fault its check exists to catch.

  wherefore prove

• Retired facts since 0.1.0

  Retire an old price, name or limit once, and nothing a person reads may say it again.

  wherefore check retired

• Reach since 0.1.0

  Wherefore changes each fact, one at a time, and checks that everything stating it changes too.

  wherefore check reach

• Claims since 0.1.0

  Give a claim like “SOC 2 certified” a rule, and no page can say more than the rule allows.

  wherefore check claims

• Derived from elsewhere since 0.5.0

  Copied something you can't pin, like a partner's spec sheet? The deploy fails the day its source changes.

  wherefore check upstream

• One palette since 0.10.0 New in 0.10.0

  Your brand lives in one file. Type a colour anywhere else and the build names the file and the line, unless the file says, with a reason, that the colour is somebody else's.

  wherefore check palette

• The pre-push hook since 0.1.0

  A push that would ship a stale document stops before it leaves your machine.

  wherefore hook install

• The skill, for Claude Code and Codex since 0.2.0

  Claude Code or Codex learns the rules from a skill that ships with each release.

What's next

The open-source engine's roadmap, as its repository states it.

• Docs from each release Next

  The product's docs, compiled from the release they describe.

• Launches that wait Later

  A launch that holds until its page, docs and demo agree.

• Drift, on the map Later

  What the scan finds - a value stated in several places that no source holds - drawn on the map beside the files that say it, so what is not yet tracked is seen, and seen shrinking.

• Your things, in one place Later #12

  An app you log in to and see every repository you connected: what each builds, what is held, and what is drifting.
