 | DEBT-0057 | Open | Modernization | Default canvas allocation size now dispatches through `PlatformServices::default_canvas_resolution`, removing the `CANVAS_RES` platform macro from `src/canvas.h`; WebGL's retained 512 default now lives in tested `pp_platform_api` policy behind injectable `pp::platform::WebPlatformServices`, but the Web shell still reaches the default implementation through the retained fallback until a dedicated Web service is injected directly | Preserve WebGL memory behavior while moving canvas creation policy out of shared canvas headers and into the platform boundary | `pp_platform_api_tests`; `ctest --preset desktop-fast --build-config Debug -R pp_platform_api_tests`; Windows app build; WebGL package smoke once root Web build exists | Default canvas resolution is owned by injected `pp_platform_*` services for every supported platform, with no WebGL branch in the legacy fallback |
 | DEBT-0058 | Open | Modernization | App-level progress/message/input dialog metadata, including message-dialog OK/cancel captions, now consumes pure `pp_app_core` through `App::show_progress`, `App::message_box`, `App::input_box`, `pano_cli plan-app-dialog`, and `pp_app_core_app_dialog_tests`; live execution is centralized in `src/legacy_app_dialog_services.*`, retained root insertion now routes through `src/legacy_ui_overlay_services.*`, and whats-new dialog state persistence routes through `src/legacy_preference_storage.*`, but the bridge still creates retained `NodeProgressBar`, `NodeMessageBox`, and `NodeInputBox` instances with raw callback/lifetime ownership | Preserve current app-shell dialog behavior while moving shared dialog policy toward UI/app services | `pp_app_core_app_dialog_tests`; `pano_cli plan-app-dialog --kind progress --total -4`; `pano_cli plan-app-dialog --kind message --cancel`; `pano_cli plan-app-dialog --kind input --ok-caption Save`; `ctest --preset desktop-fast --build-config Debug`; Windows app build | Progress/message/input dialog creation, callback wiring, layout insertion, lifetime ownership, and headless automation are owned by injected app/UI services with `App` methods acting only as adapters |

+| DEBT-0064 | Open | Modernization | `pp_paint_renderer_compositor_tests` has a test-local no-op `Texture2D::bind()` definition so retained inline stroke-preview copy helpers can be covered without linking the full app-only legacy texture implementation | `tests` are configured before `pp_legacy_engine`, and linking the app legacy texture object into this planner test would couple the renderer-neutral test target back to the app target graph | `cmake --build --preset windows-msvc-default --config Debug --target pp_paint_renderer_compositor_tests`; `ctest --preset desktop-fast --build-config Debug -R "pp_paint_renderer_compositor" --output-on-failure` | Move retained preview copy behavior behind a pure callback-only test seam or split legacy texture binding into a linkable non-app test support target, then delete the test-local `Texture2D::bind()` shim |
