# Visual–World Domain Computation — Roadmap v0.8

## 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/provenance.

## VWDC-03 — Visual World Branching, Lineage, and Evidence Transport
Sibling dependence, effective evidence, replay, invalidation, reality transport.

## VWDC-04 — Active Branch Design, Dependence-Aware World Experimentation, and Evidence Value
Replication, paired counterfactuals, falsification, external validation.

## VWDC-05 — Reality-Tethered World Calibration, Transport Contracts, and External Validity
Claim/region/version-specific RTCs and external-validity debt.

## VWDC-06 — Transport-Aware World Decisions, Policy Transfer, and Reality-Gap Robust Control
Deployment certificates, Sim2Real regret, unsupported gates, occupancy-shift debt.

## VWDC-07 — Closed-Loop Reality Feedback, Safe Policy Adaptation, and Transport-Aware Continual Worlds
Selection-aware feedback, champion–challenger, lifecycle testing, rollback and incident governance.

## VWDC-08 — Continual World Governance, Certificate Stability, and Reflexive Deployment Invariants
- mandatory certificate conjunction;
- fail-closed commit authority;
- stale concurrent proposal no-go;
- serialized commit invariance;
- robust forward-invariant certified regions;
- governance meta-state envelope;
- runtime recovery timing;
- frozen-regime best-certificate monotonicity;
- minimum-improvement churn bound;
- sparse-drift certified-time stability;
- parameter convergence non-equivalence;
- suspension when governance envelope is empty;
- regime-conditioned champion/reserve registry;
- append-only governance lineage;
- multi-world proposal/single-commit separation;
- deterministic champion arbitration;
- recovery timing and fallback availability.

## Proposed VWDC-09 — Federated World Governance, Multi-Champion Arbitration, and Shared Reality Commit Protocols
Extend the single governed commit boundary to multiple WDC runtimes and shared resources.
