# Build And Platform Inventory

Status: live
Last updated: 2026-06-02

This inventory records the known build surfaces during the CMake migration.
Keep it updated as platform paths move to shared CMake targets.

## Existing Build Entrypoints

| Platform/Target | Current Entrypoint | Notes |

## Existing Version Generation

- Script: `scripts/pre-build.py`
- Output: `src/version.gen.h`
- Current behavior: derives version from git branch, latest tag, short hash,
  commit count, and configuration argument.
- Migration requirement: root CMake should call this script through a custom
  command and avoid unnecessary tracked-file churn where possible.

## Existing Dependency Sources

Hybrid policy: migrate reliable packages to vcpkg and retain SDK/patched
dependencies until each platform triplet is proven.

| stb | `libs/stb` | Move to vcpkg or interface target if package friction |
| CURL | `libs/curl-win`, `libs/curl-android-ios` | Move to vcpkg where triplets work |
| SQLite | `libs/sqlite3` | Move to vcpkg |
| GLAD | `libs/glad` | Move to vcpkg or generated backend target |
| Catch2 | none yet | Add through vcpkg |
| OpenVR | `libs/openvr` | Retain initially |

Known local toolchain state:

- CMake: 4.0.0-rc4
- Local Visual Studio generator selected by CMake: Visual Studio 17 2022
- Bundled vcpkg: `C:\Program Files\Microsoft Visual Studio\2022\Community\VC\vcpkg`
  (`vcpkg version` reports 2025-11-19)
- Android SDK: `C:\Users\omara\AppData\Local\Android\Sdk`
- Android NDK: `C:\Users\omara\AppData\Local\Android\Sdk\ndk\29.0.14206865`
- clang-cl: `C:\Program Files\LLVM\bin\clang-cl.exe` reports 18.1.8, but the
  selected VS 2026-preview STL expects Clang 20 or newer; see DEBT-0014 before
  treating `windows-clangcl-asan` as a passing sanitizer gate.
- Android arm64 headless configure/build passes through root CMake and the
  `platform-build` automation wrapper for `pp_foundation`, `pp_assets`,
  `pp_paint`, `pp_document`, `pp_renderer_api`, `pp_renderer_gl`,
  `pp_paint_renderer`,
  `pp_ui_core`, `pano_cli`, and their current headless test binaries,
  including foundation binary-stream/event/logging/task queue coverage, PNG metadata and
  decode, PPI header/layout/non-finite opacity and blend-mode rejection, settings document, document
  snapshot/per-layer-frame/move/duration/face-pixel/PPI export coverage,
  snapshot-embedded duplicate/invalid face-payload and selection-mask rejection, paint brush/final-blend/
  stroke-alpha-blend/stroke spacing/stroke stress/stroke-script coverage,
  renderer shader descriptor and OpenGL capability coverage, UI
  color parsing, and layout XML parse coverage.
- Root CMake exposes named `fuzz` and `stress` CTest presets. `fuzz` currently
  runs deterministic parser/serializer edge tests for binary streams, image
  metadata, PPI, stroke scripts, and layout XML; `stress` currently runs the
  stroke sampler stress coverage.
- `pano_cli inspect-image` reports PNG IHDR metadata as JSON and is covered by
  `pano_cli_inspect_png_metadata_smoke` with a tiny IHDR fixture.
- `pp_assets_image_pixels_tests` decodes PNG payloads, encodes RGBA8 pixels to
  PNG, round-trips encoded pixels back through the decoder, and rejects corrupt
  or malformed image payloads.
- `pano_cli import-image` accepts a PNG path, decodes RGBA8 pixels through
  `pp_assets`, attaches them to a pure `pp_document` face payload, and is
  covered for checked-in decodable PNG import by `pano_cli_import_image_smoke`
  and metadata-valid truncated PNG rejection by
  `pano_cli_import_image_rejects_truncated_png`.
- `pano_cli export-image` writes a deterministic RGBA8 PNG through `pp_assets`
  and is covered by `pano_cli_export_image_roundtrip_smoke`, which imports the
  generated file back through `pano_cli import-image`.
- `pano_cli inspect-project` reports validated PPI thumbnail/body byte layout,
  body summary fields, layer/frame descriptors, and dirty-face PNG payload
  metadata, and is covered by `pano_cli_inspect_project_layout_smoke` with a
  minimal PPI fixture.
- `pp_document_ppi_import_tests` attaches decoded PPI dirty-face payloads to
  `pp_document` layer/frame storage and rejects payloads outside document
  layers.
- `pp_document_ppi_export_tests` exports pure `pp_document` metadata,
  per-layer frame durations, and RGBA8 face payloads to PPI bytes through
  `pp_assets`, then decodes and reimports them for round-trip coverage.
- `pano_cli simulate-document-export` exposes the same pure document-to-PPI
  export, asset-level decode, and document reimport path through JSON
  automation and is covered by `pano_cli_simulate_document_export_smoke`.
- `pano_cli save-document-project` writes that pure document export to a PPI
  file and is covered by `pano_cli_save_document_project_roundtrip_smoke`,
  which inspects and loads the generated file.
- `pano_cli load-project` creates a `pp_document` projection with per-layer
  frame counts, durations, and decoded face-pixel payloads when present; the
  metadata-only minimal fixture remains covered by
  `pano_cli_load_project_metadata_smoke`.
- `pp_assets::create_ppi_project` writes generated multi-layer, multi-frame
  PPI files with explicit per-layer names, opacity, blend mode, alpha lock,
  visibility, per-layer frame durations, and targeted dirty-face layer/frame
  payloads. `pano_cli save-project` exposes that path for automation and is
  covered by `pano_cli_save_project_roundtrip_smoke` and
  `pano_cli_save_project_payload_roundtrip_smoke`, which reload generated
  metadata-only and targeted dirty-face-payload projects through
  `pano_cli load-project`, plus
  `pano_cli_save_project_rejects_non_finite_opacity`, which verifies rejected
  automation floats do not create output files.
- `pano_cli create-document` supports `--frames` and `--frame-duration-ms` and
  is covered by `pano_cli_create_animation_document_smoke`.
- `pano_cli simulate-document-edits` exercises pure document layer/frame edit
  operations, renderer-free face payloads, and renderer-free selection masks,
  and is covered by `pano_cli_simulate_document_edits_smoke`.
- `pano_cli simulate-document-history` exercises pure document history
  apply/undo/redo behavior and is covered by
  `pano_cli_simulate_document_history_smoke`.
- `pano_cli simulate-image-import` decodes an embedded tiny PNG through
  `pp_assets`, attaches it to `pp_document`, and is covered by
  `pano_cli_simulate_image_import_smoke`.
- `pano_cli simulate-blend` exposes deterministic final RGBA and stroke-alpha
  blend reference vectors through JSON automation and is covered by
  `pano_cli_simulate_blend_smoke`.
- `pano_cli simulate-stroke` exposes the pure stroke sampler for scripted
  automation and is covered by `pano_cli_simulate_stroke_smoke`.
- `pano_cli simulate-stroke-script` loads a text stroke script fixture and is
  covered by `pano_cli_simulate_stroke_script_smoke`.
- `pano_cli apply-stroke-script` parses a text stroke script fixture, samples
  every stroke through `pp_paint`, maps the samples into a bounded
  `pp_document` RGBA8 face payload, writes a PPI file, and is covered by
  `pano_cli_apply_stroke_script_roundtrip_smoke`, which inspects the dirty-face
  box and loads the generated file back as decoded document pixel data, plus
  `pano_cli_apply_stroke_script_rejects_tiny_canvas` for invalid dimension
  rejection.
- `panopainter_validate_shaders` validates the current combined GLSL shader
  files for one vertex stage marker, one fragment stage marker, valid marker
  order, and existing relative includes.
- `pp_renderer_api` owns the canonical PanoPainter shader catalog consumed by
  the legacy OpenGL app initialization path; `pp_renderer_api_tests` validates
  catalog size, key entries, duplicate rejection, and bad path rejection.
- `pp_renderer_gl` owns headless OpenGL runtime capability detection consumed
  by the legacy app initialization path; `pp_renderer_gl_capabilities_tests`
  validates framebuffer fetch, map-buffer alignment, desktop GL float support,
  GLES float/half-float extensions, WebGL exclusion behavior, and the
  upload-type mapping used by legacy `Texture2D` and `RTT` creation, plus the
  RGBA pixel-format mapping used by `RTT` texture allocation. It also validates
  image channel-count to OpenGL texture format mapping, including
  invalid channel counts rejected by `Texture2D::create(Image)`, renderer API
  texture-format to OpenGL internal/pixel/component token mapping including
  depth-stencil formats, RGBA8/RGBA32F
  readback formats, checked byte-count math, and PBO pixel-buffer target/usage/access
  mapping used by `RTT` and `PBO` readbacks, and framebuffer status naming
  used by `RTT` and `Texture2D` diagnostics. It also owns the 2D texture target,
  framebuffer setup, readback format, mipmap target, and update component-type
  tokens used by `Texture2D`, plus cube-map binding and allocation face targets
  used by `TextureCube`. It also owns and
  validates framebuffer blit color mask and linear/nearest filters used by
  `RTT::resize` and `RTT::copy`, renderer API blit-filter to OpenGL token
  mapping, plus the default linear clamp-to-edge
  render-target texture parameters, texture/renderbuffer targets, depth format,
  framebuffer targets, binding queries, attachment points, and completion
  status used by `RTT::create` and framebuffer bind/restore paths, plus RTT
  clear color/depth masks, renderer API render-pass color/depth/stencil
  clear-mask and clear-value mapping, and color-write-mask query tokens. `RTT` no longer
  spells GL enum names directly. It also
  validates renderer API primitive-topology to OpenGL draw-mode mapping, Shape
  index-type, fill/stroke primitive-mode, buffer target, static upload usage,
  and vertex attribute component/normalization mapping used by
  the legacy mesh draw path, plus the PanoPainter cube-face to OpenGL
  texture-target mapping used by `TextureCube`.
  It also owns and validates sampler wrap S/T/R, min/mag filter, and desktop
  border-color parameter mapping used by legacy `Sampler`, plus renderer API
  sampler filter/address-mode to OpenGL token mapping including mirrored-repeat
  and aggregate renderer API sampler-state to OpenGL min/mag/wrap mapping.
  The PanoPainter
  shader attribute binding catalog, shader stage tokens, compile/link status
  queries, active-uniform count query, and matrix-uniform transpose token used
  by legacy `Shader` creation also live here. Renderer API blend factor/op to
  OpenGL token mapping is tested here with explicit support flags so `GL_ZERO`
  stays distinguishable from unsupported enum values. Aggregate renderer API
  blend-state to OpenGL enable/factor/equation/color-mask mapping, depth
  compare-op to OpenGL depth-function mapping, and aggregate renderer API
  depth-state to OpenGL enable/write/compare mapping are tested here too.
  `Shader` no longer spells GL enum
  names directly. It also owns the PanoPainter shader uniform catalog and legacy hash
  mapping used by `Shader` active-uniform discovery and the uniform uniqueness
  check. App OpenGL initialization debug severity, debug output, GL info string,
  renderer API viewport/scissor rect conversion, default depth/program-point/
  line-smooth state, blend factor/equation, and UI render-target RGBA8 format
  tokens are cataloged and tested here too, including the legacy convert command
  and resize path. App clear color-buffer masks, default framebuffer binding,
  scissor state, and sampler filter/wrap tokens also consume the backend mapping.
  OpenGL extension enumeration query tokens
  used before runtime capability detection are cataloged here. Legacy font
  atlas texture formats, text mesh buffer targets, attribute component and
  normalization tokens, draw primitive/index type, upload usage, and active
  texture unit selection also consume the backend mapping. Canvas undo/redo
  dirty-region texture updates and readbacks also consume the backend-owned 2D
  texture target, RGBA pixel format, and unsigned-byte component mapping.
  `NodeViewport` preview rendering also consumes backend-owned viewport query,
  clear-color query, color-buffer clear mask, and blend-state tokens.
  `NodeImageTexture` preview drawing also consumes backend-owned fallback 2D
  texture bind and blend-state tokens.
  `NodeImage` drawing and remote-image texture creation also consume
  backend-owned mipmapped sampler filters, blend-state tokens, and RGBA8/RGBA
  texture format mapping.
  `NodeColorWheel` triangle-buffer setup and draw-state handling also consume
  backend-owned array-buffer, static-upload, vertex-attribute, primitive-mode,
  and blend-state tokens.
  Simple UI text, text-input, border, scroll, and animation timeline draw
  paths also consume backend-owned blend-state tokens.
  Canvas layer cube/equirect generation, clear, restore, and snapshot paths
  also consume backend-owned cube/2D texture targets, active texture units,
  blend/clear state, and RGBA8 read/write pixel mapping.
  `NodePanelGrid` heightmap preview and lightmap baking also consume
  backend-owned texture readback formats, sampler filters, depth/blend state,
  depth clears, viewport queries, color-mask booleans, active texture units,
  and float render-target formats.
  Legacy `util.cpp` OpenGL error naming and `gl_state` save/restore also
  consume backend-owned error codes, state queries, framebuffer targets,
  texture binding targets, and active texture units.
  `NodeStrokePreview` brush preview rendering also consumes backend-owned
  depth/scissor/blend state, viewport/clear-color queries, active texture
  units, 2D texture targets, copy targets, and sampler filters/wraps.
  Legacy `Texture2D`, `TextureManager`, `Sampler`, and `RTT` public headers no
  longer expose raw OpenGL enum defaults; default texture formats, sampler
  filters/wraps, and render-target formats resolve through backend-owned
  overloads.
  The Windows entrypoint also consumes backend-owned generic OpenGL
  error-code/info-string tokens and WGL core-context/pixel-format attribute
  catalogs.
  The headless OpenGL command planner consumes `pp_renderer_api` recorded
  commands and maps render-pass clear masks/values, viewport/scissor state,
  blend/depth/sampler state, texture formats, primitive modes, draw counts, and
  blit filters into GL-facing planned command data while rejecting unsupported
  enum tokens before a real GL context is needed. It also plans whole recorded
  command streams, preserving per-command planned data while counting render
  passes, draws, texture uploads, mipmap generation, texture transitions,
  texture copies, texture readbacks, frame captures, passthrough commands,
  trace commands, unsupported commands, and render-pass ordering errors such as
  state changes outside a pass, nested passes, and unclosed passes.
  Desktop VR drawing also consumes backend-owned scissor/depth/blend state,
  depth clear masks, active texture units, and fallback 2D texture unbind
  targets while retaining the existing VR SDK/platform bridge shape.
  Canvas mode overlay, mask, and transform paths also consume backend-owned
  blend/depth state, active texture units, 2D texture copy targets, and RGBA8
  readback format tokens.
  `NodeCanvas` panorama UI rendering also consumes backend-owned sampler
  defaults, viewport/clear-state queries, blend/depth/scissor state, color
  clear masks, active texture units, fallback 2D texture unbind targets, copy
  targets, and RGBA8 render-target formats.
  Canvas resource setup also consumes backend-owned stroke-buffer
  RGBA8/RGBA16F/RGBA32F formats, flood-fill texture upload format/type,
  brush/stencil/mix sampler filters and wraps, and image channel-count texture
  formats for cube-strip imports. Clamp-to-border sampler wrap is now part of
  the backend capability catalog and test coverage.
  Early canvas draw helpers also consume backend-owned pick readback
  format/type, stroke mixer depth/scissor/blend state, saved viewport and
  clear-state queries, active texture units, fallback 2D texture unbind
  targets, and stroke background copy targets.
  Canvas stroke commit also consumes backend-owned saved viewport/clear/blend
  state, history readback format/type, active texture units, fallback 2D
  texture unbind targets, and layer compositing copy targets.
  Canvas layer merge rendering and explicit layer-merge compositing also consume
  backend-owned depth/blend state, active texture units, fallback 2D texture
  unbind targets, and merge framebuffer copy targets.
  Canvas equirectangular import drawing and depth export rendering also consume
  backend-owned depth/blend state and active texture units.
  Canvas thumbnail generation and object-drawing helpers also consume
  backend-owned saved viewport/clear/blend state, active texture units,
  readback format/type, framebuffer copy targets, and renderbuffer/depth
  attachment parameters; `src/canvas.cpp` no longer contains raw `GL_*`
  constants.
  Windows desktop OpenGL context creation now consumes a tested
  `windows_wgl_core_context_3_3_config()` catalog from `pp_renderer_gl` instead
  of owning active WGL context/pixel-format attribute literals in `main.cpp`.
- `windows-msvc-vcpkg-headless` validates manifest install/configure/build/test
  for the current headless component matrix; see DEBT-0007 for remaining app
  and platform triplet migration.
- `scripts/automation/analyze.*` runs shader validation plus a
  renderer-boundary guard that reports JSON and fails if active non-backend
  source code reintroduces raw `GL_*`/`WGL_*` constants outside the allowed
  legacy OpenGL implementation files.
- `pp_renderer_api` exposes a headless `RecordingRenderDevice` that reports
  renderer feature flags and validates backend-owned resource creation,
  explicit texture usage flags, command order,
  render-pass color/depth/stencil clear intent, scissor state, depth state,
  blend state, texture-slot binding, sampler-state binding, texture-upload byte
  counts, texture mip-level counts, texture/mesh/shader resource debug labels, mipmap-generation commands,
  texture-state transitions, shader-uniform writes, explicit draw descriptor ranges, texture-copy regions,
  readback/frame-capture/blit descriptor validation, readback bounds, destination buffer sizes, and
  render-target blit regions, records
  render-pass-clear/scissor/depth/blend/shader-uniform/texture-bind/
  sampler-bind/draw/upload/mipmap-generation/texture-transition/texture-copy/readback/
  frame-capture/blit commands, draw mesh inputs, explicit draw ranges, and
  records trace markers and scopes without a window or GL context. Recorder
  `clear()` also resets active render-pass and trace-scope state so automation
  can reuse the same recording device after an interrupted frame.
- `pano_cli record-render` exposes the recording renderer through JSON
  automation, including backend feature flags, render-pass/depth-clear counts, scissor/depth/blend/
  shader-uniform/texture-bind/sampler-bind/upload/mipmap-generation/texture-transition/texture-copy/readback/
  frame-capture/blit command and byte totals, trace marker/scope counts,
  labeled descriptor counts, backend resource creation counts, plus draw
  descriptor vertex/index totals. When `pp_renderer_gl` is available, it also
  emits an `openGlPlan` JSON object with the planned command count, support
  status, render-pass/draw/texture-upload/mipmap/transition/copy/readback/
  capture/passthrough/trace counts, unsupported command count, render-pass
  order error count, and unclosed-pass state. Its
  `--exercise-clear` mode verifies
  interrupted-frame recorder clear/reuse behavior and reports the result in
  JSON, and is covered by `pano_cli_record_render_smoke`,
  `pano_cli_record_render_exercises_clear_reset`, plus
  `pano_cli_record_render_rejects_oversized_target`.
- `pano_cli simulate-document-history` exposes `pp_document::DocumentHistory`
  apply/undo/redo state through JSON automation and is covered by
  `pano_cli_simulate_document_history_smoke`.
- `pano_cli simulate-document-edits` exposes `pp_document` layer metadata,
  frame order, active-index, tiny face-payload state, and selection-mask state
  through JSON automation and is covered by
  `pano_cli_simulate_document_edits_smoke`.
- `pano_cli simulate-image-import` exposes embedded PNG decode and document
  face-payload attachment through JSON automation and is covered by
  `pano_cli_simulate_image_import_smoke`.
- `pano_cli import-image` exposes file-driven PNG decode and document
  face-payload attachment through JSON automation and is covered by
  `pano_cli_import_image_smoke` and
  `pano_cli_import_image_rejects_truncated_png`.
- `pano_cli export-image` exposes deterministic RGBA8 PNG writing through JSON
  automation and is covered by `pano_cli_export_image_roundtrip_smoke`; full
  legacy canvas export remains a future CLI task.
- `pano_cli save-project` exposes generated multi-layer, multi-frame PPI
  writing with layer metadata and targeted dirty-face layer/frame payloads
  through JSON automation and is covered by metadata-only and
  dirty-face-payload round-trip smoke tests; full legacy canvas save parity
  remains tracked by DEBT-0013.
- `pp_document::export_ppi_project_document` exposes pure document-to-PPI byte
  export through CTest coverage; legacy Canvas save integration remains a
  future DEBT-0010/DEBT-0013 task.
- `pano_cli simulate-document-export` exposes document export round-trip state
  through JSON automation for agent-driven checks.
- `pano_cli save-document-project` exposes file-writing document export
  automation for inspect/load round trips.
- `pano_cli apply-stroke-script` exposes file-driven stroke-script application
  to a pure document face payload and writes a PPI artifact for inspect/load
  round-trip automation.
- `pp_ui_core` consumes vcpkg tinyxml2 only when `PP_USE_VCPKG_TINYXML2=ON`
  through the vcpkg preset; default and Android validation still use the
  retained vendored fallback tracked by DEBT-0012.

Known warnings after the current CMake app build:

- Legacy code/vendor warnings under `/W4`.
- Visual Studio vcpkg manifest warning because manifest mode is not enabled.
- `LNK4099` missing `yuv.pdb` for retained libyuv binaries.
- `LNK4098` runtime library conflict from retained vendor binaries.

Platform-specific commands should be added here when verified locally.
