# Modernization Debt Log
|
|
|
|
Status: live
|
|
Last updated: 2026-06-03
|
|
|
|
Every shortcut, temporary adapter, retained vendored dependency, skipped
|
|
platform gate, compatibility shim, or incomplete automation path must be
|
|
recorded here before it lands. Entries must be specific enough for a future
|
|
agent or engineer to remove them without reconstructing context from chat.
|
|
|
|
## Entry Rules
|
|
|
|
- Add an entry before merging the shortcut.
|
|
- Reference the debt id in code comments, TODOs, ADRs, or roadmap notes.
|
|
- Include an owner, reason, validation command, and removal condition.
|
|
- Do not close an entry until the removal condition is met and validated.
|
|
- Prefer deleting shortcuts over expanding this log.

|
|
| DEBT-0004 | Open | Modernization | Android, Linux, WebGL, Apple, and AppX build files remain platform-specific until root CMake alignment reaches them | Prevent platform regressions during incremental migration; raw Windows `.sln/.vcxproj` files were removed on 2026-05-31 by user decision | `cmake --preset windows-msvc-default`; platform-specific configure/build smoke checks as each platform is migrated | Root CMake owns every platform source list and package path |
|
|
| DEBT-0005 | Open | Modernization | Temporary local CTest harness is used before Catch2 is wired through vcpkg | `vcpkg` is not currently on PATH, but headless tests need to run now | `ctest --preset desktop-fast --build-config Debug` | Replace `tests/test_harness.h` tests with Catch2 tests once vcpkg toolchain/presets are validated |
|
|
| DEBT-0007 | Open | Modernization | `vcpkg.json` and `windows-msvc-vcpkg-headless` are validated for the headless Windows component matrix, but app targets still use vendored libraries and Android/Apple triplets are not proven | Dependency migration must stay incremental while SDK/patched/vendor dependencies remain in use | `$env:VCPKG_ROOT="C:\Program Files\Microsoft Visual Studio\2022\Community\VC\vcpkg"; cmake --preset windows-msvc-vcpkg-headless`; `ctest --preset desktop-fast-vcpkg --build-config Debug` | Component targets consume vcpkg packages where reliable and desktop app, Android, and Apple triplets are validated or explicitly documented as permanent vendor exceptions |
|
|
| DEBT-0008 | Open | Modernization | `windows-msvc-default` preset is used for local validation because the VS 2026 generator is not installed here | The target VS 2026 preset must remain, but this machine configures with Visual Studio 17 2022 | `cmake --preset windows-msvc-default`; `ctest --preset desktop-fast --build-config Debug` | Validate `windows-vs2026-x64` on a machine with Visual Studio 2026 installed and make it the default Windows validation preset |
|
|
| DEBT-0009 | Open | Modernization | Android root CMake validation currently builds headless targets only, not APK/package variants; standard arm64/x64, Quest arm64, and Focus/Wave arm64 have named root build presets and share the refreshed `platform-build` component matrix | Platform app entrypoints still live in legacy Gradle/CMake projects and need Phase 6 alignment | `powershell -ExecutionPolicy Bypass -File scripts\automation\platform-build.ps1 -Presets android-arm64`; `cmake --build --preset android-x64`; `cmake --build --preset android-quest-arm64`; `cmake --build --preset android-focus-arm64` | Android standard, Quest, and Focus/Wave package targets consume shared component targets and have package smoke commands |
|
|
| DEBT-0010 | Open | Modernization | `pp_document` is a pure layer/frame/document/undo-history model with alpha-lock metadata, snapshot construction, per-layer frame metadata, renderer-free RGBA8 face payload storage, snapshot-embedded face-payload validation, renderer-free alpha8 selection-mask storage, PPI import/export helpers, and stroke-script-to-face-payload CLI automation, but it is not yet wired to legacy `Canvas`, legacy save, or legacy action commands | Keep extraction incremental while preserving app behavior | `ctest --preset desktop-fast --build-config Debug`; `pano_cli create-document --width 64 --height 32 --layers 2`; `pano_cli load-project --path tests\data\projects\minimal-project.ppi`; `pp_document_tests`; `pp_document_ppi_import_tests`; `pp_document_ppi_export_tests`; `pano_cli_simulate_document_edits_smoke`; `pano_cli_simulate_document_export_smoke`; `pano_cli_save_document_project_roundtrip_smoke`; `pano_cli_apply_stroke_script_roundtrip_smoke`; `pano_cli_apply_stroke_script_rejects_tiny_canvas` | Legacy document behavior is represented by `pp_document` tests and the app consumes it through a boundary/facade |
|
|
| DEBT-0011 | Open | Modernization | `package-smoke` validates the Windows CMake app artifact and now reports a structured package readiness matrix for Windows AppX, Android standard/Quest/Focus APKs, Apple bundles, and WebGL output, but those package outputs are still `blocked` because root CMake package targets do not exist yet | Platform package targets are not migrated to root CMake yet | `powershell -ExecutionPolicy Bypass -File scripts\automation\package-smoke.ps1 -Preset windows-msvc-default -Configuration Debug`; `bash -n scripts/automation/package-smoke.sh` | Package-smoke builds and validates Windows AppX, Android APK variants, Apple bundles, and WebGL output where local toolchains are present |
|
|
| DEBT-0012 | Open | Modernization | `pp_ui_core` uses vcpkg tinyxml2 on `windows-msvc-vcpkg-headless`, but retains `pp_vendor_tinyxml2` for default and unproven platform presets | Mobile/AppX/Apple triplets and app packaging still need validation before removing the vendored fallback | `ctest --preset desktop-fast-vcpkg --build-config Debug`; `ctest --preset desktop-fast --build-config Debug`; `powershell -ExecutionPolicy Bypass -File scripts\automation\platform-build.ps1 -Presets android-arm64` | All supported presets consume vcpkg tinyxml2 or document a permanent vendored exception |
|
|
| DEBT-0013 | Open | Modernization | `pp_assets`, `pp_document`, `pano_cli inspect-project`, `pano_cli load-project`, and `pano_cli save-project` validate the fixed PPI header, thumbnail/body byte layout, generated multi-layer/multi-frame PPI writing with explicit layer opacity/blend/alpha-lock/visibility metadata, per-layer frame durations, metadata-only and targeted dirty-face-payload save/load round-trips, layer/frame index, dirty-face descriptors, dirty-face PNG payload metadata, asset-level RGBA PNG payload decoding, pure document-to-PPI export, CLI document export automation, file-writing document export automation, stroke-script-generated document payload export, and decoded pixel attachment to `pp_document`, but full legacy PPI round-trip parity is not yet extracted | Full PPI save parity requires staged extraction of legacy `Canvas` serialization and image/layer payload handling | `ctest --preset desktop-fast --build-config Debug`; `pp_assets_image_pixels_tests`; `pp_assets_ppi_header_tests`; `pp_document_ppi_import_tests`; `pp_document_ppi_export_tests`; `pano_cli_inspect_project_layout_smoke`; `pano_cli_load_project_metadata_smoke`; `pano_cli_save_project_roundtrip_smoke`; `pano_cli_save_project_payload_roundtrip_smoke`; `pano_cli_simulate_document_export_smoke`; `pano_cli_save_document_project_roundtrip_smoke`; `pano_cli_apply_stroke_script_roundtrip_smoke`; `pano_cli_apply_stroke_script_rejects_tiny_canvas` | Full PPI load/save fixtures cover thumbnails, decoded layer face payloads attached to documents, frames, corrupt payloads, dirty-face payload saving, arbitrary legacy canvas payload/layout combinations, and legacy app round-trip compatibility |
|
|
| DEBT-0014 | Open | Modernization | `windows-clangcl-asan` now configures as a headless Ninja/clang-cl preset and uses the release MSVC runtime required by ASan, but local builds still fail because installed clang-cl 18.1.8 is paired with VS 2026-preview STL headers that require Clang 20 or newer | Sanitizer validation should be local and repeatable, but this machine's compiler/header pairing is incompatible | `cmake --fresh --preset windows-clangcl-asan`; `cmake --build --preset windows-clangcl-asan --target pp_foundation` | Install/use Clang 20+ with the VS 2026 STL, or point the preset at a compatible VS 2022 toolchain, then make `platform-build.ps1 -Presets windows-clangcl-asan` pass for the headless matrix |
|
|
| DEBT-0015 | Open | Modernization | Cursor visibility requests now consume pure `pp_app_core` planning through `pano_cli plan-cursor-visibility`, `App::show_cursor`/`App::hide_cursor` dispatch through `PlatformServices` without platform guards, and Windows live execution uses injected `WindowsPlatformServices`, but macOS cursor execution still reaches the retained fallback adapter | Keep canvas cursor behavior stable while platform shells are extracted incrementally | `pp_app_core_document_platform_io_tests`; `pano_cli plan-cursor-visibility --visible`; `ctest --preset desktop-fast --build-config Debug` | Cursor visibility execution is owned by injected `pp_platform_*` services for every supported platform |
|
|
| DEBT-0016 | Open | Modernization | Clipboard get/set requests now consume pure `pp_app_core` planning through `pano_cli plan-clipboard-read` and `pano_cli plan-clipboard-write`, and Windows live execution uses injected `WindowsPlatformServices`, but Apple/Android clipboard execution still reaches retained fallback adapter branches from `App::clipboard_get_text` and `App::clipboard_set_text` | Keep picker/color text clipboard behavior stable while platform shells are extracted incrementally | `pp_app_core_document_platform_io_tests`; `pano_cli plan-clipboard-write --text #ff00aa`; `ctest --preset desktop-fast --build-config Debug` | Clipboard execution is owned by injected `pp_platform_*` services for every supported platform |

|
|
| DEBT-0019 | Open | Modernization | Unreferenced-parameter warnings are muted globally through `pp_project_warnings` with MSVC `/wd4100` and Clang/GCC `-Wno-unused-parameter` | Legacy callbacks, virtual hooks, serializer methods, and platform/API compatibility functions carry many intentionally unused parameters during the component split; muting this keeps stricter warning builds focused on higher-signal migration issues | `cmake --build --preset windows-msvc-default --config Debug --target PanoPainter`; `ctest --preset desktop-fast --build-config Debug`; `cmake --build --preset linux-clang --target pp_foundation` | Remove `/wd4100` and `-Wno-unused-parameter`, mark intentionally unused parameters with names/comments or `[[maybe_unused]]`, and make the Windows app plus headless Clang/GCC tests pass without unreferenced-parameter warnings |

| DEBT-0033 | Open | Modernization | Tools menu planning and direct command execution dispatch now consume pure `pp_app_core` through `App::init_menu_tools`, `pano_cli plan-tools-menu`, `pano_cli plan-tools-panel`, and the `ToolsMenuServices` boundary, but live adapters still construct legacy `NodePanelFloating` panels, mutate legacy panel nodes, clear `CanvasModeGrid`, reset `NodeCanvas` camera state, open legacy shortcuts UI, and call the iOS SonarPen bridge directly | Preserve current Tools menu behavior while UI shell actions move toward app/UI/platform services | `pp_app_core_tools_menu_tests`; `pano_cli plan-tools-menu --command shortcuts`; `pano_cli plan-tools-panel --panel layers`; `pano_cli plan-tools-panel --panel animation --already-visible`; `ctest --preset desktop-fast --build-config Debug` | Tools panel creation, submenu routing, grid clear, camera reset, shortcuts dialog, and SonarPen dispatch are owned by injected app/UI/platform services with `App::init_menu_tools` acting only as a UI adapter and no legacy Tools adapter |

| DEBT-0035 | Open | Modernization | Main toolbar/status command planning and execution dispatch now consume pure `pp_app_core` through `App::init_toolbar_main`, `pano_cli plan-main-toolbar`, and the `MainToolbarServices` boundary, and history/canvas commands now hand off through `HistoryUiServices` and `DocumentCanvasClearServices`, but the live adapter still opens legacy open/save/settings/message-box dialogs and delegates to legacy history/canvas adapters | Preserve reachable toolbar/status behavior while app shell commands move toward app/document/UI services | `pp_app_core_main_toolbar_tests`; `pano_cli plan-main-toolbar --command undo --undo-count 2`; `pano_cli plan-main-toolbar --command clear-canvas --no-canvas`; `ctest --preset desktop-fast --build-config Debug` | Open/save/settings/message-box routing, undo/redo/clear-history execution, and canvas-clear execution are owned by injected app/document/UI services with `App::init_toolbar_main` acting only as a UI adapter and no legacy toolbar adapter |

| DEBT-0036 | Open | Modernization | `pp_renderer_api`, `pp_paint_renderer`, `pano_cli plan-paint-feedback`, and `pano_cli plan-stroke-composite` can choose backend-neutral complex paint feedback strategies for fixed-function blending, framebuffer-fetch-capable renderers, or ping-pong render targets. OpenGL extension detection now stores `pp::renderer::RenderDeviceFeatures` through `ShaderManager`, using `pp_renderer_gl::render_device_features` as the backend conversion point. `pp_paint_renderer::plan_canvas_blend_gate` owns the compatibility mapping from persisted layer/brush blend indices to the extracted stroke-composite planner, and live `Canvas::draw_merge` plus `NodeCanvas` panorama rendering both call it with the stored renderer-neutral feature set for their existing shader-blend gates and destination-copy versus framebuffer-fetch decisions. `pp_paint_renderer::plan_canvas_stroke_feedback` also owns the current destination-feedback decision, and live `Canvas::stroke_draw`, thumbnail layer blending, and `NodeStrokePreview` brush-preview rendering use it for framebuffer-fetch versus destination-copy decisions. Actual live stroke rasterization, dual-brush compositing, pattern feedback math, thumbnail layer compositing, and brush-preview compositing still use legacy OpenGL canvas/UI execution | Preserve current painting behavior while the renderer boundary matures for OpenGL parity and later Vulkan/Metal experiments | `pp_renderer_api_tests`; `pp_renderer_gl_capabilities_tests`; `pp_paint_renderer_compositor_tests`; `pano_cli plan-paint-feedback --framebuffer-fetch --explicit-transitions --render-only`; `pano_cli plan-paint-feedback --texture-copy`; `pano_cli plan-stroke-composite --stroke-blend 10 --framebuffer-fetch --explicit-transitions --render-only`; `pano_cli plan-stroke-composite --layer-blend 4 --dual-blend --texture-copy`; `ctest --preset desktop-fast --build-config Debug`; `cmake --build --preset windows-msvc-default --config Debug --target PanoPainter` | Live stroke/layer compositing chooses its feedback path through `pp_paint_renderer` and renderer services, with OpenGL golden parity and Vulkan/Metal lab tests covering framebuffer-fetch and ping-pong behavior |
