Roadmap

This roadmap converts the original implementation plan into release-oriented

milestones.

0.1 Foundation

.NET 10 solution and project boundaries.
Core JSON project format.
FNA runtime host.
Avalonia editor shell.
Graph validation and IR compilation.
CLI project creation, validation, build, asset, save, release, and localization report/repair commands.

IR interpreter for dialogue, narration, variables, branch, jump, choice, and scene end.
Text window, choice UI with disabled choice states, configurable typing reveal, backlog, configurable skip and auto-forward timing, per-line interactive playback, and manual save/load.
Project-configurable runtime UI theme colors.
Project-configurable runtime UI image skin slots for dialogue, choice, save, and backlog panels.
Project-configurable runtime UI layout geometry for dialogue, choice, save, and backlog surfaces.
Project-configurable runtime UI animation settings for panel fade, selected-choice pulse, and text reveal speed.
Project-configurable runtime playback settings for auto-forward delay and skip interval.
Korean/English string table contracts, graph `textKey` validation, and runtime locale selection for localizable UI text.
Sample VN project with scenes, characters, branches, and audio placeholders.

Resource browser with search, broken references, and unused asset filters.
Scene authoring for scene selection, scene add/delete, project character add/edit/delete with reference guards, character expression sprite assignment with default/reference guards, background assignment, start graph selection, character placement add/edit/delete, visual stage layout review, layer/placement review, and dialogue UI preview.
Node graph editor with creation, duplication, deletion, linking, drag/move, inspector editing, undo/redo, and validation.
Persisted workspace layout presets, collapsible panel visibility controls, and detached Project/Scene/Graph/Inspector/Preview/Console window support for balanced, graph-focused, scene-focused, and review-oriented editor work.
Localization tab with locale review, string table diagnostics, preview locale selection, and missing-value repair.
Preview process protocol with selected locale, current node, variable state, choice history, and call stack.
Build panel profile/platform selection plus build manifest summaries and release-candidate build/package flow with forced runtime packaging, smoke-tested locales, and strict verification diagnostics.

Windows, macOS, and Linux build profiles.
Runtime publishing and asset copying.
Build log diagnostics that point to graph, scene, node, and asset IDs.
Smoke run of packaged runtime through compiled IR for each supported locale.
Build manifests that record supported locales and smoke-tested locales for release audit.
Release packaging, archive-content verification, signing, artifact upload, and draft GitHub Release creation.
Runtime audio channels for BGM, SFX, and voice playback state.

User script assembly compilation and build manifest inclusion.
Custom node/provider discovery and editor input metadata.
Editor custom script node palette.
Runtime custom command and condition node execution.
Runtime module discovery.
Project-level explicit permission settings for file system, network, and process execution.

Stable project schema and migration path, including exercised v1 to v7 migration coverage.
Crash-safe writes and undo/redo.
Release packaging and checksums.
Generated static documentation site and GitHub Pages deployment workflow.
Automated sample project build and run verification for every release.

Remaining blockers before calling the engine 1.0 stable:

Extend runtime UI skinning with richer widget states and editor-side visual animation authoring beyond the current preset-based timing controls and live layout preview.
Polish the editor into a designer-grade detachable docking experience beyond the current resizable/collapsible panels, workflow presets, and detached Project/Scene/Graph/Inspector/Preview/Console windows.
Exercise every future project schema change with a dedicated migration and regression test.
Collect live public Pages deployment evidence for the generated documentation site.
Collect live public CI evidence for Windows, macOS, and Linux release artifacts.
