A connected path through knowledge

From what you know to what you want to build.

Warren maps knowledge as connected prerequisites, finds missing steps, and guides the next concept you can use.

Why Warren exists

School organizes time. Learning depends on understanding.

Grades, schedules, and shared courses help American K–12 schools coordinate many learners. But learners begin with different prior knowledge. A shared timeline can move forward while individual prerequisites remain unclear. Later lessons can depend on those missing steps.

  • Same schedule, different starting points.

    Shared curricular windows cannot perfectly match every learner's prerequisites.

  • Feedback must arrive while it can guide practice.

    Useful feedback is specific, actionable, appropriately timed, and followed by another attempt.

  • Knowledge connects across course boundaries.

    Separate courses can make dependencies less visible, although interdisciplinary organization is not automatically better.

How Warren works

Fixed goal. Flexible path.

The destination stays visible while the route responds to the prerequisites that are already secure and the next gap that needs attention.

  1. Choose a meaningful goal

    Begin with something you want to make or understand.

    goal · selected

  2. Trace its prerequisites backward

    Follow the concepts that the goal depends on, in reverse.

    route · connected

  3. Check what is already secure

    Mark only the prerequisites that have already been demonstrated.

    concept · secure

  4. Learn and verify the next gap

    Work on the first unmet concept, then check it with another attempt.

    next gap · active

  5. Use it in a real artifact

    Put the newly connected knowledge to work in the thing you chose.

Guided graph demo

Build and deploy a small Python program

This illustrative, hand-reviewed map traces a bounded route through programming, command-line use, version control, HTTP, deployment, logic, and basic quantitative reasoning.

No learner data is stored. The route returns to its starting state when the page reloads.

  1. Start from a goal

    Highlight the goal node and its immediate dependencies.

  2. Find the next gap

    Mark a small set as secure and focus the first unmet prerequisite.

  3. Inspect trust

    Open the concept detail and explain its evidence and verification label.

Trust and AI

AI can help construct material. Evidence must earn trust.

Warren shows how each node was checked. AI supports learning; it does not take the learner's turn.

  • execution-checkedRequires the relevant example or behavior to run successfully against an expected result.
  • computation-checkedRequires a reproducible calculation to match its expected result.
  • multi-source citedRequires support from more than one named source.
  • human-signedRequires an identified person to review and approve the material.
  • not yet verifiedLabeled openly and withheld from the public demo material.

These public-demo labels are illustrative: they explain Warren's evidence categories. They are not confidence scores, production-corpus records, or measures of learner mastery.

Build status

Warren is a work in progress.

Its learning material is built and checked on locally operated GPUs. Public serving stays separate, so the site remains available while new material is being produced.
