# Modernization Task Tracker

Status: live
Last updated: 2026-06-12

This file turns the modernization roadmap into small, measurable work items.
The roadmap explains direction, the debt log explains why shortcuts remain, and
this tracker is the execution queue. Prefer closing one task here over adding a
new broad roadmap paragraph.

## Operating Rules

- Pick one `Ready` task at a time unless the user asks for planning only.
- Keep each slice small enough to validate and commit in one session.
- Do not claim percentage progress for "narrowed" debt. Points move only when a
  task row is changed to `Done`.
- A task is `Done` only when its listed checks pass, the debt log is updated or
  closed as applicable, and the roadmap/task score is updated.
- If a task proves too large, split it before editing code. The original task
  stays `Ready` or becomes `Blocked` with the reason.
- After a verified task is committed and pushed, reset conversation context
  before starting the next task when practical.
- When the user asks for subagents or delegation, follow
  `docs/modernization/director-workflow.md` and keep each delegated task mapped
  to a row in this tracker.

## Progress Scorecard

The current score is intentionally conservative. It should move in visible,
auditable steps rather than by subjective estimates.

| Area | Weight | Current | Progress Rule |
| --- | ---: | ---: | --- |
| Build and CMake ownership | 15 | 13 | Root CMake owns active source lists, app/tool targets, and retained package entrypoints. |
| Test and automation coverage | 15 | 9 | Headless, platform, package, and focused validation commands exist and are current. |
| Pure component behavior ownership | 15 | 8 | Behavior lives in `pp_*` components and is consumed by live adapters. |
| Legacy adapter retirement | 20 | 7 | `legacy_*_services` and singleton bridges are deleted or reduced to trivial composition. |
| Renderer boundary and OpenGL parity | 15 | 10 | Live render/export/readback paths execute through renderer interfaces with parity checks. |
| Platform and package parity | 10 | 6 | Required platforms have root CMake/package validation and injected platform services. |
| Hardening and future backend readiness | 10 | 0 | Edge, fuzz, golden, stress, and backend-lab gates exist for high-risk paths. |
| **Total** | **100** | **53** | Only completed tasks below may change this number. |

When updating `Current`, add a dated note under "Completed Task Log" with the
task id, points moved, validation command, and commit hash.

## Task States

| State | Meaning |
| --- | --- |
| `Ready` | Clear enough for an agent to execute. |
| `In progress` | Actively being changed in the current slice. |
| `Blocked` | Needs a user decision, missing toolchain, or a prior task. |
| `Done` | Validated, documented, committed, and pushed. |

## Ready Queue

### MT-001 - Adopt Measurable Task Tracking

Status: Done
Score: no score movement
Debt: none
Scope: `docs/modernization/tasks.md`, `docs/modernization/roadmap.md`

Steps:

- Add this tracker.
- Link it from the roadmap.
- Make the scorecard the source for percentage claims.

Done Checks:

- `docs/modernization/roadmap.md` points agents to this file.
- The tracker has task states, scoring rules, and at least one ready queue.

Validation:

```powershell
git diff -- docs\modernization\roadmap.md docs\modernization\tasks.md
```

### ADP-001 - Remove History Bridge From Document Resize And Canvas Clear

Status: Done
Score: +1 legacy adapter retirement
Debt: `DEBT-0020`, `DEBT-0027`
Scope: `src/legacy_document_canvas_services.*`,
`src/app_core/document_resize.h`, `tests/app_core/document_resize_tests.cpp`,
related canvas-clear tests only

Goal:

Make document resize and canvas-clear execution consume app-core history
commands directly instead of routing through `legacy_history_services`.

Done Checks:

- `src/legacy_document_canvas_services.*` no longer includes
  `legacy_history_services.h`.
- Resize still executes in order: resize, title update, history clear.
- Canvas clear still records undo and marks the document unsaved when a canvas
  exists.
- `docs/modernization/debt.md` narrows or closes the affected removal condition.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_app_core_document_resize|pp_app_core_document_canvas|pano_cli_plan_document_resize|pano_cli_plan_canvas_clear" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pano_cli
```

### ADP-002 - Remove History Bridge From Layer Operations

Status: Done
Score: +1 legacy adapter retirement
Debt: `DEBT-0021`
Scope: `src/legacy_document_layer_services.*`,
`src/app_core/document_layer.h`, `tests/app_core/document_layer_tests.cpp`

Goal:

Move layer add/remove/merge/clear/rename history side effects into tested
app-core execution plans so the live layer bridge no longer calls
`legacy_history_services`.

Done Checks:

- `src/legacy_document_layer_services.*` no longer includes
  `legacy_history_services.h`.
- Layer operations still preserve undo/history behavior covered by
  `pp_app_core_document_layer_tests`.
- `pano_cli plan-layer-operation`, `plan-layer-menu`, and
  `plan-layer-rename` JSON remains compatible.
- `docs/modernization/debt.md` records the narrowed or closed layer-history
  adapter dependency.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_app_core_document_layer|pano_cli_plan_layer" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pano_cli
```

### ADP-003 - Remove History Bridge From Document Open And Session Save

Status: Done
Score: +1 legacy adapter retirement
Debt: `DEBT-0039`, `DEBT-0040`, `DEBT-0042`
Scope: `src/legacy_document_open_services.*`,
`src/legacy_document_session_services.*`,
`src/app_core/document_session.*`, `src/app_core/document_route.*`,
matching tests only

Goal:

Make document-open, close, save, save-before-workflow, Save As, and Save Version
history effects explicit app-core outputs instead of direct
`legacy_history_services` calls in the live bridges.

Done Checks:

- `src/legacy_document_open_services.*` and
  `src/legacy_document_session_services.*` no longer include
  `legacy_history_services.h`.
- Existing dirty-document, save-before, new-document, Save As, and Save Version
  plans preserve their JSON contracts.
- The debt log is updated for every debt id listed above.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_app_core_document_route|pp_app_core_document_session|pano_cli_plan_open_route|pano_cli_simulate_app_session|pano_cli_plan_document_file|pano_cli_plan_document_version" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pano_cli
```

### ADP-004 - Make Dialog Creation A UI Factory Boundary

Status: Done
Score: +2 legacy adapter retirement
Debt: `DEBT-0058`, `DEBT-0063`
Scope: `src/legacy_app_dialog_services.*`,
`src/legacy_ui_overlay_services.*`, `src/app_dialogs.cpp`,
`src/app_core/app_dialog.h`, dialog tests only

Goal:

Keep app-core dialog metadata pure, but move retained
`NodeProgressBar`/`NodeMessageBox`/`NodeInputBox` construction behind one
`pp_panopainter_ui` or retained UI factory function. `App` should ask for a
dialog object through an interface instead of knowing individual node creation
details.

Done Checks:

- `App::show_progress`, `App::message_box`, and `App::input_box` still preserve
  captions, cancel behavior, and keyboard behavior.
- New factory path has focused tests or existing `pp_app_core_app_dialog_tests`
  plus a smoke command proving the live adapter still builds.
- The debt log states exactly which raw-node lifetime hazards remain.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_app_core_app_dialog|pano_cli_plan_app_dialog" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pano_cli
```

### ADP-005 - Convert One Popup/Dialog Family To Checked Overlay Lifetime

Status: Done
Score: +2 legacy adapter retirement
Debt: `DEBT-0063`
Scope: choose exactly one family from `src/node_dialog_open.cpp`,
`src/node_dialog_browse.cpp`, `src/node_panel_quick.cpp`,
`src/node_panel_stroke.cpp`, or `src/node_combobox.cpp`, plus
`src/legacy_ui_overlay_services.*`

Goal:

Adopt `pp_ui_core` overlay lifetime semantics for one retained popup/dialog
family before trying to rewrite all retained UI nodes.

Done Checks:

- The chosen family no longer owns open-coded root insertion, outside-click
  release, close callback wiring, or destroy-during-callback behavior.
- Existing UI behavior is preserved.
- Tests cover missing root/template handling and close/release behavior for the
  chosen family.
- The debt log names the completed family and the remaining families.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_ui_core_overlay_lifetime|pp_ui_core_node_lifetime" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter
```

### RND-001 - Make Pure Equirectangular Export The Primary Success Path

Status: Done
Score: +2 renderer boundary and OpenGL parity
Debt: `DEBT-0010`, `DEBT-0036`, `DEBT-0043`
Scope: `src/legacy_document_export_services.*`,
`src/app_core/document_export.*`, `src/paint_renderer/compositor.*`,
`tests/app_core/document_export_tests.cpp`,
`tests/paint_renderer/compositor_tests.cpp`

Goal:

For payload-complete snapshots, live PNG/JPEG equirectangular export should
complete through the pure document/paint-renderer writer. Retained
`Canvas::export_equirectangular*` should run only for unsupported Web,
incomplete-readback, or writer-failure fallbacks.

Done Checks:

- Export route reports whether the pure writer was used or why fallback was
  required.
- Tests cover pure-writer success and each fallback reason.
- Live bridge does not call retained equirectangular export after pure-writer
  success.
- The debt log narrows retained equirectangular export execution.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_app_core_document_export|pp_paint_renderer_compositor|pano_cli_plan_export_snapshot_route|pano_cli_simulate_document_export" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pano_cli
```

### RND-002 - Make Pure Layer And Animation Collection Export Primary

Status: Done
Score: +2 renderer boundary and OpenGL parity
Debt: `DEBT-0010`, `DEBT-0036`, `DEBT-0043`
Scope: `src/legacy_document_export_services.*`,
`src/app_core/document_export.*`, `src/paint_renderer/compositor.*`,
collection export tests only

Goal:

For payload-complete snapshots, live layer and animation-frame collection export
should complete through the pure collection writer. Retained
`Canvas::export_layers*` and `Canvas::export_anim_frames*` should run only for
unsupported Web, incomplete-readback, or writer-failure fallbacks.

Done Checks:

- Collection export route reports pure-writer success versus fallback reason.
- Tests cover layer collection, animation-frame collection, and fallback.
- The debt log narrows retained collection export execution.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_app_core_document_export|pp_paint_renderer_compositor|pano_cli_plan_export_snapshot_route" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pano_cli
```

### RND-003 - Replace Depth Export Readiness With Pure Depth Export Execution

Status: Done
Score: +3 renderer boundary and OpenGL parity
Debt: `DEBT-0010`, `DEBT-0036`, `DEBT-0043`
Scope: `src/paint_renderer/compositor.*`,
`src/app_core/document_export.*`, `src/legacy_document_export_services.*`,
depth tests only

Goal:

Turn the current pure depth export render plan into actual payload generation
for payload-complete snapshots, then write image/depth payloads through the
existing app-core two-payload writer before falling back to retained
`Canvas::export_depth*`.

Done Checks:

- Pure depth export produces deterministic image and depth payloads for a
  payload-complete snapshot.
- Retained depth export runs only for unsupported targets, incomplete readback,
  or writer failure.
- Tests cover malformed depth target inputs and byte-size validation.
- The debt log narrows depth export readback/execution.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R "pp_app_core_document_export|pp_paint_renderer_compositor|pano_cli_plan_export_snapshot_route" --output-on-failure
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pano_cli
```

### RND-004 - Add First Desktop GPU Golden Gate

Status: Blocked
Score: +2 hardening and future backend readiness
Debt: `DEBT-0036`
Scope: `tests/`, `CMakeLists.txt`, renderer test helpers only

Goal:

Create the first non-default `desktop-gpu` golden/readback test that validates
one OpenGL output against a deterministic fixture. Keep it opt-in so headless
agents are not blocked.

Done Checks:

- `ctest --preset desktop-gpu --build-config Debug` has at least one real test.
- The test is skipped with a clear message when no GPU/context is available.
- The roadmap and debt log describe what the golden covers and what remains.

Validation:

```powershell
ctest --preset desktop-gpu --build-config Debug --output-on-failure
ctest --preset desktop-fast --build-config Debug -R "pp_renderer_gl|pp_paint_renderer" --output-on-failure
```

### PLT-001 - Split Apple Picker/Browse Service From Legacy Platform Adapter

Status: Done
Score: +2 platform and package parity
Debt: `DEBT-0017`, `DEBT-0051`, `DEBT-0055`
Scope: `src/platform_legacy/legacy_platform_services.*`, new
`src/platform_apple/*` files if needed, `CMakeLists.txt`, platform API tests

Goal:

Move macOS/iOS document browse roots, file picking, directory picking, and
display-path formatting out of the catch-all legacy platform adapter and into a
named Apple platform service boundary.

Done Checks:

- `src/platform_legacy/legacy_platform_services.*` no longer owns Apple
  browse/picker policy.
- Apple compile validation still passes through the remote build script.
- The debt log narrows Apple platform shell extraction.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R pp_platform_api_tests --output-on-failure
powershell -ExecutionPolicy Bypass -File scripts\automation\apple-remote-build.ps1 -Presets macos,ios-simulator,ios-device
```

### PLT-002 - Split Web Export/Storage Policy From Legacy Platform Adapter

Status: Done
Score: +2 platform and package parity
Debt: `DEBT-0050`, `DEBT-0053`, `DEBT-0057`
Scope: `src/platform_legacy/legacy_platform_services.*`, new
`src/platform_web/*` files if needed, `src/platform_api/*`, platform tests

Goal:

Move WebGL exported-image publishing, persistent-storage flushing,
prepared-file handoff, and default canvas resolution out of the catch-all
legacy platform adapter into a named Web platform service boundary.

Done Checks:

- Web policy is injectable through `pp_platform_api`.
- The legacy adapter no longer owns Web default canvas resolution or storage
  flush policy.
- Package-smoke readiness still reports Web blockers explicitly.

Validation:

```powershell
ctest --preset desktop-fast --build-config Debug -R pp_platform_api_tests --output-on-failure
powershell -ExecutionPolicy Bypass -File scripts\automation\package-smoke.ps1 -ReadinessOnly
```

### DEP-001 - Remove Generated fmt Overlay

Status: Done
Score: +1 build and CMake ownership
Debt: `DEBT-0062`
Scope: `CMakeLists.txt`, `cmake/`, `vcpkg.json`, `libs/fmt` or package wiring

Goal:

Use a supported fmt package or update the vendored fmt release so VS 2026 no
longer needs a generated `format.h` overlay.

Done Checks:

- No build-tree fmt header overlay is generated.
- `DEBT-0062` is closed.
- Windows app and at least one focused component test build pass.

Validation:

```powershell
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter pp_platform_api_tests
ctest --preset desktop-fast --build-config Debug -R pp_platform_api_tests --output-on-failure
```

### DEP-002 - Remove Generated nanort Overlay

Status: Done
Score: +1 build and CMake ownership
Debt: `DEBT-0060`
Scope: retained Android package CMake, `libs/nanort`, grid/lightmap dependency
wiring
Goal:

Update, replace, or isolate `nanort` so Android package builds do not generate
a patched vendor overlay.

Done Checks:

- Android retained package CMake no longer generates a patched `nanort.h`.
- `DEBT-0060` is closed.
- Standard Android retained package validation passes.

Validation:

```powershell
powershell -ExecutionPolicy Bypass -File scripts\automation\android-legacy-package-build.ps1 -Packages standard
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter
```

## Blocked Or Later Queue

These are real goals, but they should not be picked until prerequisite tasks
above have reduced risk.

### LATER-001 - Replace OpenVR With OpenXR
