# V9 Documentation Guide

This guide is the curated front door to V9, **Metis: A Curious Ape's Guide to
Reality**—the consumer learning product that composes the Oshun knowledge,
science, generative, agentic, simulation, and contemplative systems into a
grounded journey from wonder to durable mastery. Its contract is not merely a
beautiful answer: every claim is sourced or computed, every activity has a
reachable success state, every lesson is pedagogically scoped, and every
generated surface remains auditable.

V9 is an integration and productization version. Its originating product and
feature documents set the target; the derived backlog, unified Atlas and lesson
contracts, runtime composition, gates, tests, learner evidence, deployment, and
operations establish what is supported.

## Lesson truth model

```mermaid
stateDiagram-v2
  [*] --> Wonder
  Wonder --> Scoped: learner prerequisites and concept frontier resolved
  Scoped --> Grounded: sources and computed kernels pinned
  Grounded --> Planned: solve-first objectives activities and assessment exist
  Planned --> Realized: narrative media explorable and tutor surface generated
  Realized --> Gated: G1 through G7 produce versioned verdicts
  Gated --> Compiled: immutable verified skeleton and regenerable surface bundled
  Compiled --> Delivered: eligible learner cohort receives lesson
  Delivered --> MasteryObserved: assessment and retrieval evidence updates model
  Scoped --> Withheld: prerequisites sources rights or policy absent
  Realized --> Regenerate: quality modality or surface failure
  Gated --> Rejected: truth pedagogy completeness safety or provenance failure
  Delivered --> Retracted: source correction regression or policy change
```

Do not infer grounding from fluent citations, accuracy from model agreement,
pedagogy from content length, completeness from a rendered widget, mastery from
engagement, or release readiness from a generated lesson fixture. Numerical and
scientific claims use canonical source pins or computed kernels; every
explorable has a demonstrably reachable success state; gate verdicts are tied to
immutable lesson versions; and learner-model updates preserve consent and
auditability.

## Recommended reading journey

```mermaid
journey
  title From V9 wonder to durable mastery
  section Wonder
    Resolve intent prerequisites and learning goal: 5: Learner, Atlas
    Pin sources kernels and misconception risks: 5: Sophia, Kalika, Nyx
  section Forge
    Plan explain explore assess and continue: 5: Prometheus
    Realize tutor media and interactive surfaces: 4: Chiron, Hephaestus
  section Verify

    Schedule retrieval and the next better question: 5: Mnemosyne, Theia
```

### Product, curriculum, and experience design

Start with the [feature index](../features/README.md). Define learner state,
question, prerequisite frontier, objective, misconception risks, source/kernel
authority, explorable success state, assessment evidence, modality fallbacks,
and continuation. Preserve the science/human braid without presenting metaphor,
generated narrative, or contemplative framing as empirical fact.

### Knowledge, agent, and runtime engineering

Start with the [architecture index](../architecture/README.md). Trace a wonder
through Atlas, source/kernel grounding, Prometheus, Aletheia, media/explorable
realization, Chiron, the lesson artifact, delivery, Mnemosyne mastery, and Theia
continuation. Preserve concept/source/kernel/claim identifiers, seeds,
model/prompt/tool envelopes, gate verdicts, artifact versions, and consented
learner updates.

### QA, pedagogy, accessibility, governance, and operations

Exercise ambiguous wonders, missing prerequisites, contested or retracted
sources, unit/numerical errors, impossible interactives, misconception traps,
assessment leakage, unsafe/sensitive topics, age/region/entitlement denial,
voice/avatar/WebGL/WASM fallback, localization, offline/partial behavior,
provider loss, budget exhaustion, cache/version conflict, retraction, and
rollback. Evaluate learning and truth separately from engagement and aesthetic
quality.

## Page-set organization

- [Feature index](../features/README.md) — eight focused topics covering product
  overview, subsystem gates, wonder/forge, teacher/explorables, mastery,
  braid/commons/media, and governance/boundaries.
- [Architecture index](../architecture/README.md) — nine focused topics covering
  overview, reuse, Atlas, Prometheus, Hephaestus, lesson artifact, gates, and
  web-first cross-cutting delivery.
- [V9 diagram atlas](./diagram-atlas.md) — wonder/lesson flow, typed learning
  data, lesson state, composition, ownership, learner journey, and release.
- Root product/gap/research/dependency/backlog/review documents — why, evidence,
  source boundaries, delivery truth, and remaining work.

## Documentation quality contract

Every canonical page remains substantial, indexed exactly once, visually
explicit, and precise about sourced/computed/generated content, immutable versus
regenerable artifacts, learner consent, gate versions, mastery evidence, and
release state. Changes update contracts, knowledge/source/kernel data,
tests/evals, backlog/research/evidence, retraction, and runbooks together.
Generated integrity, freshness, search, gallery, and desktop/mobile checks pass.
