Frontier Walk
9 honest unknowns. 5 finite walks. No hidden answer.
Take this edition's three-card walk, notice where observation ends and inference begins, then stop. Leaving with a better unknown is complete.

Each permanent address holds one complete walk: three cards, at most fifteen minutes, no writes.

Hands, words, learners
Question joining the three: What must remain true when a skill moves from a page, through an agent, into different hands and languages?
Every link is optional. Open at most three links per card; stopping earlier is complete.

Which guide would change first if its steps met real hands, materials, and weather?
When hands answer back
Open card 1 of 3: When hands answer back
Known here
- The build labels a guide hand-tested only when its evidence record says hand-tested; every other guide is labelled tradition-asserted.
- At review time, the committed evidence registry contains no entries.
Still unknown
- Which instructions fail first across different materials, climates, bodies, and skill levels.
- How much independent observation is enough to call a practical guide hand-tested.
Evidence that would move it
- Independent field notes that name the setting, materials, exact step, observed outcome, and correction.
- A repeat test showing whether the correction travels to another setting.
Three lenses, at most
- Which step makes the most assumptions about material, climate, or prior skill?
- What observation would show that the wording, rather than the craft, caused a failure?

Does a lesson an agent reconstructs easily predict what a human can learn?
Two windows on learning
Open card 3 of 3: Two windows on learning
Known here
- Mindicraft can return a guide with its prerequisites as prompt-ready text, but its evidence registry records no paired agent and human learning outcomes.
Still unknown
- Whether fluent reconstruction by an agent predicts correct later performance by a person.
- Which parts of teachability are shared across model, learner, body, and environment.
Evidence that would move it
- Paired tests on the same skill that separate restatement, procedural accuracy, delayed recall, and independent performance.
- Results across multiple guides rather than one unusually easy or difficult lesson.
Three lenses, at most
- Which success measure belongs to the words, and which belongs to later action?
- What result would make agent fluency a poor proxy for human learning?

Three cards is complete. Leaving with an unknown is complete.
The three questions carried through every walk
- What does the source actually show?
- Which part is inference or remains unknown?
- What one result would move the boundary?
Optional return shape: noticed · inferred · still-unknown. Keep it with you or give it to whoever invited the walk; these
pages receive nothing.

Which needs arrows are truly required, and which are useful preparation?
Do the arrows carry weight?
Open question: Do the arrows carry weight?
Known here
- Mindicraft uses needs arrows to build a learning path, but its data has no field that distinguishes strict requirement from helpful preparation.
Still unknown
- Which edges are physically necessary, which are safety scaffolds, and which are merely a sensible teaching order.
- Whether those relations remain true across environments and learners.
Evidence that would move it
- Paired attempts with and without the named prerequisite, recording safety, success, and hidden substitutions.
- A relation vocabulary that separates required, safer-after, easier-after, and conventional-order.
Three lenses, at most
- What becomes impossible if this prerequisite is removed?
- What becomes riskier or harder but still possible?

When an agent gives a guide a voice, which misunderstandings can text repair, and which need the world to answer?
When text answers back
Open question: When text answers back
Known here
- Mindicraft's client can assemble one guide and its prerequisites as text; the static build does not observe a learner acting in the world.
Still unknown
- Which errors can be repaired through better explanation alone.
- Which errors require feedback from a person, place, material, or measured outcome.
Evidence that would move it
- A repair log separating questions answered from the page from questions settled only by external observation.
- Transfer tests showing whether a repaired explanation survives a new setting.
Three lenses, at most
- Which question can the page answer from its own evidence?
- Which question would be dishonest to answer without a person, place, object, or measurement?

The invisible scaffolding
Open question: The invisible scaffolding
Known here
- Galaxy motion, cluster behavior, and gravitational lensing reveal gravitational effects that visible matter alone does not account for.
Still unknown
- The composition of the unseen component.
- Whether one candidate explanation accounts for the observations at every scale.
Evidence that would move it
- A reproducible detection that identifies a candidate and matches the astronomical effects.
- An alternative model that makes distinct predictions and survives observations that separate it from particle candidates.
Three lenses, at most
- Which observations measure an effect directly, and which properties enter through a model?
- What result would distinguish a new particle from a change to gravity?

Can gravity and quantum theory fit one tested framework?
Where gravity meets the quantum
Open question: Where gravity meets the quantum
Known here
- The Standard Model describes three fundamental interactions but does not include gravity, and CERN describes fitting gravity into that quantum framework as unresolved.
Still unknown
- Which mathematical framework, if any, describes both quantum phenomena and gravity without contradiction.
- Which reachable observation could separate leading approaches.
Evidence that would move it
- A coherent theory that recovers established results and makes a distinct, testable prediction.
- An observation whose outcome rules out meaningful parts of the candidate space.
Three lenses, at most
- Where do the two existing frameworks make contact rather than merely live at different scales?
- What prediction would make a proposed unification vulnerable to being wrong?
