# Visual–World Domain Computation — Roadmap v0.5

## VWDC-01 — From Visual Reachability to Runnable World Reachability
Observation, liftability, dynamics closure, runnable contract.

## VWDC-02 — Compositional Visual–World Reachability Graphs
Typed visual/world paths, lift/fork/render composition, path defects and provenance.

## VWDC-03 — Visual World Branching, Lineage, and Evidence Transport
Sibling dependence, ESS, replay, invalidation, world-to-reality error boundary.

## VWDC-04 — Active Branch Design, Dependence-Aware World Experimentation, and Evidence Value
Evidence-purpose branch selection, falsification, external validation, STOP.

## VWDC-05 — Reality-Tethered World Calibration, Transport Contracts, and External Validity
- claim-specific Reality Transport Contract;
- target/state/action/task scope;
- marginal-cancellation no-go;
- conditional/subtrace validation;
- local discrepancy maps;
- partial validation coverage debt;
- counterfactual joint non-identifiability;
- calibration/discrepancy confounding;
- multi-dataset evidence fusion;
- shared external bias;
- distribution-shift debt;
- world/reality version drift;
- continual contract expiry/revalidation;
- three-part world/transport/measurement error;
- regional Lipschitz extrapolation;
- semantic alignment;
- support/positivity boundary;
- assumption-indexed claim scope.

## Proposed VWDC-06 — Transport-Aware World Decisions, Policy Transfer, and Reality-Gap Robust Control
Use RTCs to govern reality-facing policy/action deployment.
