V5 — Features (Page Index) — Open-World Narrative

This directory holds the V5 (a UE5 open-world narrative universe of six "ruleset cells") feature map, decomposed from the single ../V5_features.md hub into focused, in-depth, code-grounded pages. The hub remains the canonical entry point and preserves every section heading; each page below expands one part of the product with richer, code-grounded detail and an honest implemented / spec-only status. The companion architecture reference lives in ../architecture/.

Cross-reference convention. Page-to-page links are relative (./<slug>.md); the architecture companion for a feature page is linked as ../architecture/<slug>.md. Platform-foundation links point at the shared platform/ space.

The landscape separates the six-cell product scope from shared foundations and from actual implementation maturity. Each cell owns distinct movement, combat, world, narrative, and content rules; Mind Palace and platform services compose them through versioned contracts.

Use this index to choose the player/cell/cross-cell promise, then pair it with the closest architecture page. Follow authored truth and rights through runtime, authority, persistence, presentation, services, and evidence. Finally check backlog, dependencies, product review, current corpus/assets/code/tests/builds, and release/operational evidence before assigning a completion state. A plugin shell, research note, fixture case, or shared base class does not prove a supported cell.

Every focused feature page appears exactly once below. The V5 documentation guide explains the six-cell truth model and role paths; the diagram atlas provides case, data, state, module, production, and release models. Cross-links preserve relationships without duplicating canonical ownership.
