| AGE movie decode (`0x236` scene movies; `0x20f` modal LOGO/OP/ED; `0x24d` movie masks) | `FfmpegMovieDecoder` is the sole factory over the project-owned `native/age_movie_ffmpeg` ABI | Windows-x64 and Linux-x64 both pass the complete 213-payload installed video/audio corpus gate. The Linux library bundle is present in a validated Godot export; Windows also passes audible LOGO/OP/CHAPTER playback and real TEST.AGF green-mask decode | Add macOS native builds, distributable source-offer packaging, and real Linux/macOS window/audio movie gates |
| Movie integration | Each surface owns a unique playback-instance id; `MovieRuntime` owns `IMovieDecoder` from an injected factory; video-only streams use monotonic pacing while audio-bearing streams use the Godot output clock. Opcode `0x24d` redirects decoded green bytes through the platform-neutral retained rasterizer and exact managed packed-alpha mask helper | Concurrent/restarted uses of one asset have independent frame/audio/completion/teardown state. Ordinary and mask movies share VFS/FFmpeg ownership; the mask result is a backend-neutral dynamic RGBA surface consumed by either Godot renderer. Managed code is no longer Windows-annotated, and target-aware builds stage either the win-x64 or Linux-x64 native bundle | Add macOS native builds and Linux/macOS in-engine smoke gates |
| Movie audio | ABI v2 returns timestamped stereo float PCM; bounded managed buffering feeds a per-playback Godot `AudioStreamGenerator` and routes native movie flags to engine buses | All 29 installed audio-bearing streams decode with signal; synchronized LOGO/OP/CHAPTER playback is audibly accepted | Treat absent, distorted, or unsynchronized audio from an audio-bearing movie as a runtime bug |
| ADV font discovery/raster fidelity | `Age.Engine.Text` remains OS-neutral. On compatible ACP-932 Windows, `auto` selects the separate exact `Age.Engine.Text.Windows` GDI gray-4 backend. Otherwise Godot TextServer supplies Unicode masks and metrics from ordered system-font substitutions in `godot/config/himegari-text-rendering.json`; this policy is explicitly not GDI pixel-exact. Immediate `0x204`/`0x205`, live ADV, retained History, and the wait atlas all enter ordinary RGBA surfaces/retained handles | Three Mincho/Gothic regular/bold samples byte-match an independent Unicode GDI oracle. Forced exact and forced portable self-tests cover immediate, live, and History rasterization, bounded caching, complete-line materialization, retained ordering, alpha/tint/fade, transforms, clipping, capture, HIDEWIN suspension, partial erase/republication, reset, and teardown. Gameplay `Label` pools and overlay projection are gone | Produce and smoke-test Linux/macOS exports, confirm installed family availability/fallback selection there, and keep the GDI project out of non-Windows deliverables |
| ADV font discovery/raster fidelity | `Age.Engine.Text` remains OS-neutral. On compatible ACP-932 Windows, `auto` selects the separate exact-to-request `Age.Engine.Text.Windows` GDI gray-4 backend. Otherwise Godot TextServer supplies Unicode masks and metrics from ordered system-font substitutions in `godot/config/himegari-text-rendering.json`; this policy is explicitly not GDI pixel-exact. Immediate `0x204`/`0x205`, live ADV, retained History, and the wait atlas all enter ordinary RGBA surfaces/retained handles | Three Mincho/Gothic regular/bold samples byte-match an independent Unicode GDI oracle. A live `SC0000@0x869` trace proves that the `AGE Patch.exe`/`jprun.dll` wrapper overrides authored Mincho to MS Gothic: 13 captured masks match Gothic byte-for-byte and Mincho 0/13. This is wrapper behavior, not the true-native default. Forced exact and forced portable self-tests cover immediate, live, and History rasterization, bounded caching, complete-line materialization, retained ordering, alpha/tint/fade, transforms, clipping, capture, HIDEWIN suspension, partial erase/republication, reset, and teardown. Gameplay `Label` pools and overlay projection are gone | Optionally expose realized-face overrides through future launch profiles when wrapper compatibility is desired; independently produce and smoke-test Linux/macOS exports, confirm installed family availability/fallback selection there, and keep the GDI project out of non-Windows deliverables |
| Filesystem semantics | Several filename and containment comparisons use `OrdinalIgnoreCase`; installed assets are conventionally uppercase | Needs validation on case-sensitive filesystems; may hide casing or containment mistakes | Add Linux/macOS tests with mixed-case synthetic roots and use filesystem-appropriate containment rules |
| Save/profile/settings storage | `Sys4PersistencePaths` models AGE's independent `SAVEPATH` and `REGFILEPATH` resolutions. Godot replaces Himegari's related profile directory with `user://`, yielding `user://SAVE` for native S3SD/S4SD/S3RT files and thumbnails plus `user://SYS4REG.INI` for the BOM-less CP932 options file; the preserving writer changes only its nine `[sound]` keys | Save payloads and engine options are isolated together without changing either native format. Native/drop-in resolution remains available through `USEAPPDATAFOLDER` plus both SYS4INI paths. A single-root override is rejected when `SAVEPATH` is not beneath `REGFILEPATH`, preventing cross-profile guesses | Expose explicit profile/native selection through the future launcher and allow independent overrides for profiles whose two native paths are unrelated. Validate CP932 availability, replace/flush, case, permissions, and interrupted-write behavior on each export target |
| Game-install, runtime metadata, and repository discovery | `GameRootSelection` accepts `--game-root`, then probes the executable directory and current working directory for `SYS4INI.BIN`; on Unix the frontend prefers inherited shell `PWD` because Godot may change the process directory during project startup. Godot injects the selected root into its catalog and loose-first ALF store. `Himegari.csproj` embeds generated `build/opcodes.json`, and the frontend loads that assembly resource rather than `Paths.OpcodesJson`. `Paths.cs` remains a development/test locator; its page-map use is compiled only for `TOOLS` builds | Installed game data and packaged VM metadata no longer depend on the workspace sibling layout. The Linux export passed an explicit absolute game root outside the repository and read the installed archives. Exported automatic page maps use `user://diagnostics/page-maps`; editor/development runs preserve `build/page-map-<SCENE>.jsonl` | Let the future profile launcher pass `--game-root`, and run executable-directory/CWD plus case/permission smoke gates on Linux and macOS |
