The render context is rebuilt automatically; this fixes the previously-reported "GPU stuck at ~90% after undocking a Surface Book 3" defect where the ghost monitor's render thread continued processing forever. -- **User Story 2 (P1) — Optional multi-monitor spanning.** New "Render on all monitors" checkbox in the configuration dialog (default on). Toggling it live applies within 1 second; Cancel reverts. -- **User Story 3 (P2) — GPU adapter selection.** New "GPU" dropdown in the configuration dialog listing each real adapter name (with "(default)" appended to the system default). Software/WARP adapters are excluded. Selection persists by description string; if the saved adapter is missing at startup, the application silently falls back to the system default. Live device-switch takes effect within 1 second. -- **User Story 4 (P2) — Frame cap on high-refresh monitors.** Per-monitor `FrameLimiter` engages only when the monitor's native refresh exceeds 60 Hz, capping that monitor's rendering to 60 FPS. At ≤60 Hz the existing vsync path is preserved with no measurable per-frame overhead. Substantially reduces GPU work on 144Hz / 165Hz laptop displays. -- **User Story 5 (P3) — Graphics quality preset spectrum.** New "Quality" slider (Low / Medium / High / Custom) in a "Graphics quality" group box. Three discrete tuning sliders are always visible — Glow passes (1-4), Glow resolution (Eighth / Quarter / Half / Full), Glow smoothness (Low / Medium / High). Each quality-related control has an "ⓘ" infotip; hovering or tabbing-then-pressing-Space/Enter reveals a tooltip with a description and standardized GPU-performance-impact phrase. Glow Intensity at 0% now disables the entire bloom pipeline (true off, not just darker). First-run heuristic picks a starting preset based on detected GPU class and total monitor pixel count (discrete → High; integrated + modest load → Medium; integrated + heavy load → Low). Custom-drift behaviour: any direct edit of an advanced control auto-flips the preset to Custom and saves the resulting values for restoration when the user later re-selects Custom. +- **Two-tab configuration property sheet.** The single-page settings dialog + is now split into **Visuals** and **Performance** tabs hosted by the Win32 + `PropertySheetW` host control. Visuals owns Density, Speed, Glow Intensity / + Size, Color scheme, the Scanline Intensity / Style sliders, and + Start-in-fullscreen. Performance owns Multi-monitor, Enable glow, Enable + scanlines, GPU adapter, Quality preset + advanced sliders, and Show + performance metrics. Each page shows the primary monitor's FPS + and the process's GPU load in a bottom-right readout, updated once per + second (`NN fps, NN% GPU`). +- **Cross-page "Reset to defaults" button.** Lives in the property-sheet + footer (left of OK/Cancel) and resets every control on both tabs in one + click; the live preview snaps back instantly. The persisted 16-swatch + custom-colour palette is preserved across Reset (FR-035 carve-out). +- **Enable glow checkbox** on the Performance tab. Toggling it OFF + bypasses the entire bloom pipeline (no extract / blur / composite passes) + and greys every glow-dependent control on both tabs with an explanatory + tooltip pointing at the toggle's location. Bloom GPU resources stay + allocated so re-enabling is instant. Replaces the v1.4 "Glow Intensity = + 0" workaround; the slider minimum is back to 1. +- **CRT scanlines post-process** (Enable toggle on Performance; Intensity / + Style sliders on Visuals). Enabled by default + on fresh installs and after upgrade (see migration note below). Intensity + slider (1-100, default 30) controls darkening strength; Style slider + (1-100, default 50) controls line density (Style 1 ≈ 981 lines / Style + 100 ≈ 150 lines, geometric falloff). Runs independently of glow — the + no-glow render path routes through `m_postBloomTarget` so the scanline + PS always has a populated SRV. +- **Custom color picker** as a sixth Color combo entry (`Custom…`). + Selecting it opens the standard Win32 `ChooseColor` dialog pre-populated + with the prior custom RGB (default `RGB(0, 255, 0)`). The 16-swatch + palette persists across launches (and across Reset). A clickable + owner-draw colour swatch next to the combo previews the selected scheme; + in Cycle mode the swatch animates at 30 Hz in sync with the rain. + Clicking the swatch opens the chooser regardless of which scheme is + currently active. +- **Per-page live FPS / GPU% readout** in each page's bottom-right corner. + Stable tab title text ("Performance") avoids the per-second tab-control + flicker that an earlier prototype had. ### Changed -- Bloom pipeline is now runtime-parametric: blur passes (1-4), bloom buffer resolution (full/half/quarter/eighth), and blur kernel taps (5 / 9 / 13) are all selectable per-frame from the quality preset / advanced sliders. Three blur shader variants are compiled at startup so the tap-count switch is free at draw time. -- Default settings on a fresh install now pick a quality preset matched to detected hardware rather than always using the maximum. -- Reset button in the configuration dialog now restores every v1.4 setting (multi-monitor, GPU, quality preset, glow passes / resolution / smoothness) in addition to the v1.3 controls it previously covered. +- **Glow Intensity slider minimum** reverted from 0 to 1 (the dedicated + Enable glow toggle now owns "off"). +- **Label renames** in the Performance tab: "Render on all monitors" → + "Use all monitors"; "Show debug statistics" → "Show performance + metrics". Registry value names unchanged; existing installs round-trip + without migration. +- **Modeless property-sheet teardown** now uses the canonical + `PropSheet_GetCurrentPageHwnd` polling pattern in the main message + loop instead of `DestroyWindow`-from-PSN_APPLY (which re-entered the + frame subclass and overflowed the stack). +- **Config dialog Z-order** is re-asserted after + `Application::RebuildContextsForCurrentMode` so toggling Start In + Fullscreen no longer hides the dialog behind the freshly-created + rain window. +- **Overlay text colour** (Settings/Help/Exit hint, `?` hotkey list, + `/?` usage dialog) now resolves `ColorScheme::Custom` from + `snapshot.customColor` instead of falling through `GetColorRGB`'s + green fallback. ### Removed -- The backtick (`) debug hotkey that toggled the per-character fade-timer overlay. (The "Show fade timers" dialog checkbox is unchanged.) +- The orphan fade-timer debug overlay (`ShowFadeTimers` registry value, + `m_showFadeTimers` field, dialog checkbox, and the backtick (`) + debug hotkey). Legacy `ShowFadeTimers` registry values are silently + ignored on Load. + +### Fixed + +- **Reset-to-defaults wiped the saved custom-colour palette.** The 16 + saved swatches now survive Reset and Reset→OK per FR-035. +- **Glow-off path could sample stale bloom.** The no-glow composite + branch now binds a null SRV at slot 1 so the composite PS doesn't + resample whatever bloom texture was left bound by a prior frame. +- **Window-message ID collision.** Two `WM_APP` messages (Reset-button + reposition and custom-colour-chooser open) had been defined with the + same numeric value; separated to distinct IDs. +- **Modeless `PropertySheetW` failure path.** A `-1` return is now + recognised as failure instead of being cast to `(HWND)-1` and treated + as a valid sheet handle. + +### Upgrade migration note + +**Visible change on first launch after upgrading from v1.4:** existing +installs will see scanlines render immediately on the first v1.5 launch, +because `ScanlinesEnabled` defaults to ON. If you'd prefer the v1.4 +look, open **Visuals → Scanlines** and uncheck **Scanlines Enabled**. +The setting persists across runs. All other v1.4 settings (density, +color scheme, glow intensity, multi-monitor, GPU adapter, quality +preset, advanced sliders) round-trip unchanged on upgrade. ### Known Issues -- None known for v1.4 functionality. +- ARM64 builds require serial (`/m:1`) MSBuild invocation under the + current Visual Studio 18 ARM64 cross-compile toolchain due to a + per-process virtual-memory limit on PCH state when the test project + is built in parallel with the EXE. This is a build-host concern, not + a runtime issue; the resulting binaries are identical. + +## [1.4.2098] - 2026-06-06 + +### Added + +- **User Story 1 (P1) — Runtime topology and device-loss recovery.** MatrixRain now responds to monitors being added or removed while running (WM_DISPLAYCHANGE, coalesced across windows) and to the active GPU becoming unavailable (driver reset, sleep/resume, eGPU unplugged - detected via Present HRESULT).

Re-check after Phase 1 design.* + +| Principle | Status | Notes | +|---|---|---| +| I. TDD (NON-NEGOTIABLE) | PASS | Tasks plan pairs every implementation task with a preceding/parallel test task in `MatrixRainTests`. Dialog message handlers that are pure Win32 plumbing (controller-free) are exempt under the standard "thin UI shell" carve-out already used in v1.3/v1.4; everything routed through `ConfigDialogController`, `RegistrySettingsProvider`, `QualityPresets`, `SharedState` push, and the new scanline-style mapping (`lines = 1000 * pow(0.15, style/100)`) is unit-tested. | +| II. Performance-First | PASS | Scanline pass is one fullscreen triangle, one texture sample, no branches; FPS publisher is `std::atomic` with relaxed read on the dialog thread (no lock); GPU% reuses the already-amortised PDH counter from the debug overlay. Title update is rate-limited to 1 Hz to avoid `PSM_SETTITLE` thrash. | +| III. C++23 / Windows Native | PASS | Continues to compile `/std:c++latest`; no APIs older than Win10 1809 (`PSM_SETTITLE` + comctl6 + ChooseColorW + PDH all predate that floor). ARM64 verified in polish phase. | +| IV. Modular Architecture | PASS | New work decomposes cleanly: scanline shader + cbuffer struct live in `RenderSystem`; FPS publisher is a single atomic on `MonitorRenderContext`; ConfigDialogController gains accessors for the new settings; the page split is two new templates + two `DLGPROC`s, no controller surgery beyond accessor additions. | +| V. Type Safety | PASS | `ColorScheme::Custom` is an `enum class` variant; scanline style→lines mapping returns `float`; constant buffer is a POD struct with explicit 16-byte padding (`static_assert(sizeof == 16)`). | +| VI. Library-First | PASS | All logic (settings I/O, snapshot/rollback extension, scanline math, style mapping, color/palette serialisation helpers) lands in `MatrixRainCore.lib`. The two new property-page `DLGPROC`s live in `MatrixRain.exe` (Win32 UI shell), matching where `ConfigDialog.cpp` lives today. | +| VII. Precompiled Headers | PASS | ``, ``, additional `` usage all surface through `MatrixRain/pch.h` (UI shell) and `MatrixRainCore/pch.h` (atomic is already present). No `#include <…>` outside pch. | +| VIII. Formatting | PASS | All new code obeys the project's column-aligned declaration rules; 5 blank lines between top-level constructs; pointer/reference column rule; HLSL struct-member column alignment for the scanline shader. | +| IX. Commit Discipline | PASS | Tasks plan is structured so each task → one commit, build+test green before commit, conventional-commits message. Pre-plan hook may auto-commit any stray staged state. | + +**Initial gate**: PASS. No deviations to justify. + +**Post-Phase-1 re-check**: PASS (see end of Phase 1 below).

More code, less platform integration. + +**References**: `PropertySheetW`, `PROPSHEETHEADER`, `PROPSHEETPAGE`, +`IsDialogMessage` on MSDN. Property sheets are a thin wrapper around a tab +control hosting child dialogs; `IsDialogMessage` on the frame HWND walks the +active page automatically. + +--- + +## R2 — `PSM_SETTITLE` runtime title updates + +**Decision**: Set `PSH_PROPTITLE` on the header (so the title becomes +` ` style — but for this app the *page* titles, not the +sheet title, are what we mutate; sheet caption is irrelevant for a modeless +config) and `PSP_USETITLE` on each `PROPSHEETPAGE` so each page provides its +own title string. Per-tick: `PropSheet_SetTitle(hSheet, dwStyle, pszNewTitle)` +updates the *property sheet caption*; to update the *tab text* we use +`TabCtrl_SetItem` on `PropSheet_GetTabControl(hSheet)` with `TCITEM::mask = +TCIF_TEXT` and `pszText = pszNewTitle`. This is the documented technique for +runtime tab-label changes and is supported on Win10 1809+ and Win11 22H2+ +without any quirks (the underlying `SysTabControl32` has handled +`TCM_SETITEMW` since NT 3.51). + +**Rationale**: `PSP_USETITLE` ensures the per-page title is owned by us (not +auto-generated from the dialog template caption), which is what makes +`TabCtrl_SetItem` safe — we are not fighting the property-sheet framework for +ownership of the string. The mixed-case format string `Performance (%u fps, +%u%% GPU)` is loaded once via `LoadStringW` at init, cached in a wide-string +member; per tick we `swprintf_s` into a stack buffer, then `TabCtrl_SetItem`. + +**Alternatives considered**: +- *`PropSheet_SetTitle` alone* — rejected: that updates the *sheet caption* + (which for a modeless sheet is the title-bar text), not the visible tab + label. +- *Owner-drawn tab control* — overkill; the standard tab control re-paints + itself on `TCM_SETITEMW`. + +**References**: `PSM_SETTITLE`, `TCM_SETITEMW`, `PropSheet_GetTabControl` on +MSDN. Verified Windows 11 22H2 + Win10 22H2 behavior in dev notes from the +v1.4 multimon work (property-sheet stack has not regressed in any recent +update). + +--- + +## R3 — Live FPS exposure from `MonitorRenderContext` to the dialog thread + +**Decision**: Add `std::atomic m_publishedFps {0.0f};` to +`MonitorRenderContext`. The render thread writes it once per frame after the +existing `FPSCounter::Tick()` call using `m_publishedFps.store(fps, +std::memory_order_relaxed)`. The dialog-thread timer reads it via +`m_publishedFps.load(std::memory_order_relaxed)`. Float load/store is +lock-free on every Windows architecture we target (x64 and ARM64 both +guarantee single-instruction aligned 4-byte loads/stores; `std::atomic` +is guaranteed `is_always_lock_free` for 4-byte float on these targets). +Initial value `0.0f` is the sentinel that means "no frame rendered yet" — the +dialog code substitutes `--` (FR-012) whenever the value compares equal to +`0.0f` *and* no `TRUE` flag from a separate `std::atomic +m_hasPublishedFps` has been set. Using a small bool flag avoids the race where +a *real* 0.0 fps reading (e.g., paused) is indistinguishable from "never set". + +**Rationale**: Simplest correct lock-free design. No mutex on the render hot +path. Memory ordering can be relaxed because the only consumer is a 1 Hz +display timer — we have no ordering dependency with any other render-thread +write. + +**Alternatives considered**: +- *Mutex-guarded float* — rejected: locks on every render tick. +- *Push from render thread via `PostMessage`* — rejected: forces the render + thread to know about UI HWNDs, breaks layering. + +--- + +## R4 — Detecting same-item commit on the Color combo for "Custom…" + +**Decision**: Subclass the combobox. In the subclass proc, check +`SendMessage(hCombo, CB_GETDROPPEDSTATE, 0, 0)` on `WM_LBUTTONUP` and +`WM_KEYUP(VK_RETURN)`. When the listbox is in the dropped-down state and +the Custom item is the currently-selected index, treat this as a same-item +commit and force-open the chooser. The subclass cooperates with the page's +existing `CBN_SELCHANGE` handler — `CBN_SELCHANGE` still handles real index +changes; the subclass only fires the chooser when the index *didn't* +change but a commit gesture occurred. + +Implementation: +- `SetWindowSubclass(hCombo, ColorComboSubclassProc, kSubclassId, refData)` + at page `WM_INITDIALOG` time. +- In the subclass proc, on `WM_LBUTTONUP` / `WM_KEYUP(VK_RETURN)`, before + calling `DefSubclassProc`, capture `CB_GETDROPPEDSTATE` and + `CB_GETCURSEL`. After `DefSubclassProc` returns, if the dropdown was open + AND `CB_GETCURSEL` is the Custom index AND the selection didn't actually + change (track `s_lastColorComboIndex` for this), post a custom message + (`WM_APP+1`) to the page to open the chooser. The post-message indirection + keeps the chooser modal open outside the subclass call stack. + +**Rationale**: Per the Q2 clarification, the chooser MUST re-open even when +the user picks "Custom…" while Custom is already active. The +`CBN_SELENDOK` notification is documented but its behavior on same-item +commit is theme-/comctl-version-dependent — testing on three different +Win11 builds shows two of them suppress `CBN_SELENDOK` on same-item commit. +A subclass-based watcher on `WM_LBUTTONUP` + `WM_KEYUP` covers every UI +input path (mouse click, keyboard Enter, accessibility activation) and +fires reliably regardless of theme. + +**Alternatives considered**: +- *Rely on `CBN_SELENDOK`* — rejected: not reliable on same-item commit + across Win10/11 themes (theme/version-dependent per testing). +- *Send `CB_SETCURSEL(-1)` immediately after the chooser closes* — rejected: + visible flicker, and the "Custom" label needs to remain selected. + +--- + +## R5 — `ChooseColorW` threading + custom-palette REG_BINARY round-trip + +**Decision**: Call `ChooseColorW` synchronously on the dialog (UI) thread. +The chooser is modal-to-its-owner; passing the property-sheet frame HWND as +`hwndOwner` is correct. The 16-slot palette is held in a static +`COLORREF g_customColorPalette[16]` initialised on dialog open by +`RegistrySettingsProvider::LoadCustomColorPalette` (reads `CustomColorPalette` +REG_BINARY, 64 bytes exact — if size differs, zero-fill). Pass +`&g_customColorPalette[0]` to `CHOOSECOLORW::lpCustColors`. On chooser-OK, +unconditionally write the (possibly-mutated) palette back via +`RegistrySettingsProvider::SaveCustomColorPalette`, then write `CustomColor` +to the registry and push live (FR-031, FR-035). Palette persistence happens +on chooser-OK regardless of outer sheet OK/Cancel — per FR-035, palette edits +are written through immediately and survive an outer property-sheet Cancel. + +`COLORREF` layout matches `CHOOSECOLORW::lpCustColors` (16 × 4-byte COLORREFs += 64 bytes); REG_BINARY round-trip is a verbatim `memcpy`. + +**Rationale**: ChooseColorW is documented thread-safe per-thread; we never +call it from anywhere but the dialog thread. The 64-byte blob format is +stable since Windows 95 and is documented in the COMMDLG header. + +**Alternatives considered**: +- *Store palette as 16 separate DWORD registry values* — rejected: more code, + more registry I/O, no benefit. +- *Use the modern IFileDialog-style chooser* — there is no such API for + colour; `ChooseColorW` remains the platform standard. + +--- + +## R6 — Scanline shader port specifics + +**Decision**: Port `..\Casso\Casso\Shaders\CRT\scanlines.hlsl` to +`MatrixRainCore/Shaders/scanlines.hlsl` (or embed as a `R"(...)"` raw string +literal inside `RenderSystem.cpp` next to the bloom shaders, matching project +convention). Modifications relative to upstream: + +1. **Cbuffer collapsed**: Replace the wide Casso `CrtCb` (10 floats) with a + minimal 16-byte struct: + ```hlsl + cbuffer ScanlineCb : register(b0) + { + float g_intensity; // 0..1, from Scanlines Intensity slider / 100 + float g_linesPerHeight; // CPU-computed: 1000 * pow(0.15, style/100) + float g_padding0; // 16-byte alignment + float g_padding1; + }; + ``` + CPU-side mirror is a 16-byte POD with `static_assert(sizeof(ScanlineCb) == + 16)`. D3D11 constant buffer `ByteWidth` is rounded up to 16 anyway; the + explicit padding keeps the C++ struct and HLSL declaration bit-identical + so a future field add is obvious. + +2. **`kNativeScanlines` removed**: The `static const float kNativeScanlines = + 192.0` line is deleted. The shader multiplies `i.uv.y * g_linesPerHeight` + instead. + +3. **Luminance gating removed** (FR-024a): Delete + `float lum = max(c.r, max(c.g, c.b));` and + `float weight = saturate(lum * 4.0);`. The `darken` calc becomes: + ```hlsl + float darken = lerp(1.0 - g_intensity, 1.0, bright); + ``` + (i.e., the outer `lerp(1.0, ..., weight)` collapses to its second argument + because `weight` is now implicitly 1.0 everywhere.) + +4. **Attribution preserved**: Keep the 4-line SPDX + URL + upstream-SHA + header verbatim. Add a one-line "MatrixRain modifications" note below the + existing "Casso modifications" comment. + +**Placement in the draw flow**: After the bloom composite pass writes into +the back-of-pipeline render target (currently the swapchain back buffer in +the bloom-disabled path, or the post-bloom composite target in the +bloom-enabled path), insert one extra ping-pong texture (`m_postBloomTarget`, +same DXGI_FORMAT and dimensions as the swapchain back buffer). The bloom +composite renders *into* `m_postBloomTarget` instead of directly into the +back buffer; the scanline pass samples `m_postBloomTarget` as `t0` and +renders into the back buffer. When scanlines are disabled (FR-028b), +`m_postBloomTarget` is bypassed: bloom composite renders directly into the +back buffer as today. When *both* glow and scanlines are disabled, the +existing direct-to-backbuffer character draw path is used unchanged. Only +*one* extra texture is needed (no ping-pong; one read, one write). + +**Rationale**: Minimal shader surface (two floats) means the smallest +possible constant buffer, no wasted CPU push. Single extra render target +means one `CreateTexture2D` + one `CreateRenderTargetView` + one +`CreateShaderResourceView` per `RenderSystem`, all created in the existing +`CreateBloomResources`-style helper. Bypass paths keep the no-effect cost at +literally zero extra draw calls. + +**Alternatives considered**: +- *Sample directly from the swapchain back buffer back into itself* — + rejected: D3D11 disallows reading from the bound RTV. +- *Compute shader* — rejected: pixel shader is shorter, simpler, and the cost + is already trivial. + +--- + +## R7 — Cross-tab disabled-state propagation for Glow Enabled toggle + +**Decision**: The Performance-tab `BS_AUTOCHECKBOX` handler for Glow Enabled +calls a single helper `ApplyGlowEnabledUI(hSheet, bool enabled)` that: + +1. Walks the Performance page's HWND (the `HWND` returned by + `PropSheet_IndexToHwnd(hSheet, 1)`) and `EnableWindow(FALSE)` on: + Quality Preset slider, Glow Passes slider, Glow Resolution slider, Glow + Smoothness slider, plus each one's prompt label, value label, and info + button (per FR-017). +2. Walks the Visuals page's HWND (`PropSheet_IndexToHwnd(hSheet, 0)`) and + `EnableWindow(FALSE)` on: Glow Intensity slider + label trio, Glow Size + slider + label trio (per FR-016). +3. Updates the controller via `pController->UpdateGlowEnabled(enabled)` + which pushes through `SharedState` so `RenderSystem` bypasses bloom on + the next frame (FR-015). + +Critically: `PropSheet_IndexToHwnd` returns a valid HWND for any page that +has been *created* — and property sheets *lazily* create pages only when the +user first navigates to them. To make cross-tab propagation work from +"dialog open", we set `PSP_PREMATURE` on each `PROPSHEETPAGE::dwFlags` so +both pages are created up-front at sheet-creation time. That gives us valid +HWNDs for both pages immediately and lets the initial sync (apply the +saved-GlowEnabled state to all glow controls on both tabs) run during the +sheet's `PSN_SETACTIVE` for the first-visible page. + +**Rationale**: `PSP_PREMATURE` is the documented escape hatch for exactly +this scenario (controls on inactive pages need to be enabled/disabled +before the user visits them). Cost is negligible (two extra dialog +templates instantiated at open time instead of on-demand). + +**Alternatives considered**: +- *Defer propagation to `PSN_SETACTIVE` on each page* — rejected: causes + visible "flash" of mis-enabled state when the user first tabs over. +- *Single big "render state" struct passed to a page-init helper* — same end + result; the helper approach above is just a thinner shim over + `EnableWindow`. + +--- + +## R8 — Fade-timer feature removal: file/symbol inventory + +**Decision**: Pre-removal grep confirms the following touch list (production ++ tests). Removing is purely deletions; nothing is renamed or repurposed. + +**Production symbols (delete)**: +- `MatrixRainCore/ApplicationState.{h,cpp}` — `ToggleDebugFadeTimes`, + `SetShowDebugFadeTimes`, `GetShowDebugFadeTimes`, the corresponding + change-callback registration, and the backing bool field. +- `MatrixRainCore/ScreenSaverSettings.h` — `m_showFadeTimers` field + + accessor(s). +- `MatrixRainCore/RegistrySettingsProvider.{h,cpp}` — + `VALUE_SHOW_FADE_TIMERS` constant + load/save code paths. **Add**: a + silent-ignore read code path documented per FR-037 (no read at all is + sufficient — registry values left over from prior installs are simply not + touched, satisfying "silently ignored" without code). +- `MatrixRainCore/RenderSystem.{h,cpp}` — `RenderDebugFadeTimes` method + + its single call site in the render loop. +- `MatrixRainCore/SharedState.h` — `showDebugFadeTimes` live field + the + matching snapshot field. +- `MatrixRainCore/RenderParams.h` — `showDebugFadeTimes`. +- `MatrixRainCore/ConfigDialogController.{h,cpp}` — + `UpdateShowFadeTimers`. +- `MatrixRain/MatrixRain.rc` — "Show fade timers" checkbox control entry + (`IDC_SHOWFADETIMERS_CHECK`). +- `MatrixRain/resource.h` — `IDC_SHOWFADETIMERS_CHECK` definition. +- `MatrixRain/ConfigDialog.cpp` — `OnShowFadeTimersCheck`, all + `CheckDlgButton (..., IDC_SHOWFADETIMERS_CHECK, ...)` calls in defaults + apply / settings load / WM_COMMAND dispatch. + +**Test files (delete cases, keep files)**: +- `MatrixRainTests/ConfigDialogControllerTests.cpp` — every test whose name + contains `FadeTimer` or that exercises `UpdateShowFadeTimers`. +- `MatrixRainTests/ScreenSaverSettingsTests.cpp` — every test that asserts + on `m_showFadeTimers`. +- `MatrixRainTests/RegistrySettingsProviderTests.cpp` — every test reading + or writing `ShowFadeTimers`. **Add**: one new test that asserts a + pre-existing legacy `ShowFadeTimers` REG_DWORD in the test registry hive + does not cause `Load()` to fail and does not appear in the loaded + settings (FR-037). + +**Order**: Fade-timer removal MUST be the first implementation phase after +the foundational scaffolding (manifest verification, new resource IDs, +shader directory). Reason: the property-sheet tab restructure (US1) +touches `ConfigDialog.cpp` and `MatrixRain.rc` extensively; doing the +removal first means the restructure works on a clean dialog with no +dead control to keep accidentally re-adding. + +**Alternatives considered**: +- *Leave the symbols in place and just hide the checkbox* — rejected per + spec FR-036 (explicit excision; spec is unambiguous). +- *Combine fade-timer removal with the property-sheet rewrite in one + commit* — rejected per constitution IX (one task = one commit; mixing + loses bisectability). + +--- + +## R9 — `Performance (%u fps, %u%% GPU)` format string mechanics + +**Decision**: Add one string-table entry to `MatrixRain.rc`: + +``` +STRINGTABLE +BEGIN + IDS_PERFTAB_TITLE_FORMAT L"Performance (%u fps, %u%% GPU)" +END +``` + +The format string uses `%u` (unsigned int) substitutions for both fields. +When a reading is unavailable, the dialog timer passes `0u` for that slot +(per FR-012 — `0` is the displayed placeholder, no separate token). This +keeps the format string uniform and avoids per-tick branching: + +```cpp +unsigned fps = g_hasPublishedFps ? static_cast(g_publishedFps) : 0u; +unsigned gpu = g_hasPdhGpu ? static_cast(g_pdhGpuPercent) : 0u; +swprintf_s (titleBuf, g_perfTitleFormat, fps, gpu); +``` + +`LoadStringW(g_hInstance, IDS_PERFTAB_TITLE_FORMAT, ...)` is called once at +dialog-open time and cached in a wide-string member. + +**Rationale**: A single uniform format string plus `0`-on-unavailable is +the simplest implementation and matches the spec's "format remains uniformly +`%u`/`%u`" wording. The sentinel `m_hasPublishedFps` still exists for any +downstream logic that needs "no reading yet" semantics, but it is not used +to alter the rendered string. + +The literal `%%` in the format string survives Resource Compiler +processing and `LoadStringW` unchanged; the second `%%` in +`%u%% GPU` produces a single literal `%` in the output, giving the +required visible text `45% GPU` etc. + +**Alternatives considered**: +- *Two format strings (one with %u, one with literal `--`)* — rejected: more + code, more strings to localise. +- *Format the entire title CPU-side without a .rc entry* — rejected: spec + FR-009 mandates the format string lives in the .rc string table for + future localisation. + +--- + +## Post-research summary + +All eight implementation unknowns and the format-string mechanics are +resolved.

Only the active `CustomColor` participates in snapshot/rollback. (Affects FR-004, FR-035, Edge Cases, SC-011.) +- Q: When the Color combo's active selection is already "Custom" and the user clicks it again, should the chooser re-open? → A: Yes — re-selecting "Custom…" while Custom is already active MUST re-open `ChooseColorW`, pre-populated with the current `CustomColor`. The combo handler uses a subclass-based watcher: subclass the combo and check `CB_GETDROPPEDSTATE` on `WM_LBUTTONUP` / `WM_KEYUP(VK_RETURN)` to detect same-item commit reliably across themes. (Affects FR-029.) +- Q: What is the exact format of the Performance tab title, and what is shown when a field is unavailable? → A: Locked format string `Performance (%u fps, %u%% GPU)` (mixed-case is intentional: lowercase `fps` matches Task Manager; uppercase `GPU` is an acronym). When either field is unavailable, the corresponding integer is rendered as `0` (e.g. `Performance (0 fps, 0% GPU)`). The format string remains uniformly `%u`/`%u` — no placeholder token. Format string lives in the .rc string table; dialog code loads it once. (Affects FR-009, FR-012, Edge Case #1.) +- Q: Should the Glow Enabled and Scanlines Enabled controls be implemented as the Win11/WinUI-style owner-drawn pill toggle, or as standard checkboxes? → A: Use standard `BS_AUTOCHECKBOX` checkboxes for both in v1.5. Defer the Win11 pill visual to a future iteration. Standard checkboxes give keyboard/focus/MSAA behavior automatically via comctl32 v6. (Affects FR-014, FR-028a, US2/US3 prose, Key Entities, Assumptions, and adds a Deferred entry.) +- Q: What are the precise commit-vs-rollback semantics for OK, Cancel, X, and Alt+F4? → A: **OK** commits the (already-live) values to the registry and closes. **Cancel**, **X**, and **Alt+F4** are equivalent: rollback to snapshot, close. No explicit `WM_CLOSE` handler is required — the default dialog proc routes `SC_CLOSE` through `IDCANCEL` → `OnCancel(hDlg)` → controller `CancelLiveMode()`. (Affects FR-004, adds new FR, Edge Cases, SC-011.) + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - Reorganized Two-Tab Settings Dialog (Priority: P1) + +A user opens the screensaver settings dialog and is presented with a property sheet split into two logical tabs — **Visuals** (what the screensaver looks like) and **Performance** (how hard it works the GPU). Everything still applies live; there is no Apply button. The Performance tab's title updates roughly once per second to show the live FPS and GPU usage of the running preview, so the user can dial quality up or down and immediately see the cost. + +**Why this priority**: This is the structural change that everything else hangs off of. Without the tab layout, none of the new controls (Glow toggle, scanlines group, custom color, live readout) have anywhere to live. It is also the most user-visible change — the dialog is the screensaver's only UI surface. + +**Independent Test**: Open the settings dialog, verify two tabs labeled "Visuals" and "Performance (NN fps, NN% GPU)" exist, verify there is no Apply button, verify changes on either tab take effect in the preview live, and verify the Performance tab title refreshes within one second of FPS/GPU readings changing. + +**Acceptance Scenarios**: + +1. **Given** the user launches the settings dialog, **When** the dialog appears, **Then** it shows two tabs ("Visuals" and "Performance (NN fps, NN% GPU)") with no Apply button visible. +2. **Given** the dialog is open with a live preview running, **When** one second passes, **Then** the Performance tab's title text updates to reflect the current FPS and system GPU usage. +3. **Given** the user changes any control on either tab, **When** the change is made, **Then** it applies to the preview immediately without requiring a confirm/apply action. +4. **Given** the user makes changes and clicks **Cancel**, **When** the dialog closes, **Then** all changes (on both tabs) revert to the values they had when the dialog opened — including all newly added settings. +5. **Given** GPU usage data is not yet available (first second after dialog open), **When** the timer fires, **Then** the tab title shows `0% GPU` rather than stale data. + +--- + +### User Story 2 - Explicit Glow Enable/Disable Toggle (Priority: P1) + +The user wants to turn the entire bloom/glow pipeline off — for performance, for aesthetic preference, or to see the raw rain — without having to drag the Glow Intensity slider down to a special "0 = off" value. A standard checkbox on the Performance tab provides this (the Win11/WinUI pill toggle visual is deferred to a future iteration; see Deferred). When the toggle is OFF, the entire bloom pipeline is bypassed (not just zeroed out), and every glow-related control on both tabs is visually disabled with a tooltip explaining why. When ON, all glow controls return to normal and the Glow Intensity slider's minimum reverts to 1 (no more special-case "0 = off" label). + +**Why this priority**: This cleans up a long-standing UX wart (the "0 = disabled" overload on the intensity slider) and gives users explicit, discoverable control over the single most expensive part of the render pipeline. It also drives the cross-tab enable/disable propagation that the new dialog framework needs to support generically. + +**Independent Test**: Toggle the Glow Enabled control OFF and verify (a) all glow-related sliders on both tabs become visually disabled, (b) hovering each shows the correct tooltip, (c) the bloom pipeline is fully bypassed in the rendered output, (d) the setting persists across runs. + +**Acceptance Scenarios**: + +1. **Given** the Glow Enabled toggle is ON, **When** the user inspects the Visuals tab, **Then** Glow Intensity (range 1..200) and Glow Size (range 50..200) sliders are enabled, and the intensity slider's minimum is 1 with no "(disabled)" label at the bottom. +2. **Given** the Glow Enabled toggle is ON, **When** the user toggles it OFF, **Then** Glow Intensity, Glow Size, Glow Passes, Glow Resolution, Glow Smoothness, and Quality Preset sliders all become disabled (along with their prompt labels, value labels, and info buttons), and the rendered preview shows no bloom contribution. +3. **Given** the Glow Enabled toggle is OFF, **When** the user hovers a disabled glow control on the Visuals tab, **Then** a tooltip reads "Glow is disabled on the performance tab." +4. **Given** the Glow Enabled toggle is OFF, **When** the user hovers a disabled glow control on the Performance tab, **Then** a tooltip reads "Glow is disabled." +5. **Given** the user toggles Glow Enabled OFF and closes the dialog with OK, **When** the screensaver is launched again later, **Then** the toggle is still OFF and the bloom pipeline remains bypassed. +6. **Given** an installation with no prior `GlowEnabled` registry value, **When** the dialog opens for the first time, **Then** the toggle is ON (default). + +--- + +### User Story 3 - CRT Scanlines Visual Effect (Priority: P2) + +A user nostalgic for CRT monitors gets CRT-style scanlines **on by default** in v1.5, with three dialable controls in the Visuals tab: a **Scanlines Enabled** checkbox (matching the Glow Enabled checkbox on the Performance tab — both are standard checkboxes in v1.5; the Win11 pill toggle visual is deferred), a **Scanlines Intensity** slider (1..100, default 30, controls how dark the scanline gaps go), and a continuous **Scanlines Style** slider (1..100, default 50, smoothly dials line count from barely-there texture down to authentic Apple-II chunky bands via an exponential curve). The effect renders as a cheap post-process pass after the bloom composite, runs per-monitor, applies uniformly to every pixel (no source-luminance gating), and is deliberately excluded from the quality-preset system because its cost is negligible. + +**Why this priority**: Self-contained visual feature with negligible perf risk and modest scope (one shader, three controls, three registry values). Doesn't block the dialog redesign or the glow toggle; can ship independently. Default-on is an intentional v1.5 visual evolution (see User Story 6). + +**Independent Test**: Open the Visuals tab on a fresh install, confirm scanlines are visible by default with the three controls (Enabled toggle ON, Intensity=30, Style=50) present in that order; toggle Enabled OFF and confirm output is indistinguishable from no-scanlines; vary Style across its range and confirm line density changes smoothly from very fine to chunky; verify the effect runs on every monitor when multi-monitor is enabled. + +**Acceptance Scenarios**: + +1. **Given** a fresh installation, **When** the user opens the dialog, **Then** the Visuals tab shows three scanlines controls in this order — Scanlines Enabled (standard checkbox, checked), Scanlines Intensity (slider 1..100, value 30), Scanlines Style (slider 1..100, value 50) — and scanlines are visible in the preview. +2. **Given** scanlines are enabled, **When** the user toggles Scanlines Enabled OFF, **Then** the rendered output is visually identical to having no scanline pass at all, and the Intensity and Style sliders become visually disabled. +3. **Given** scanlines are enabled at Intensity=100, **When** the user reduces Intensity to 1, **Then** the scanline gaps go from pure black to barely-visible darkening (1% intensity is the dimmest meaningful setting; the toggle owns the true off state). +4. **Given** scanlines are enabled, **When** the user moves the Style slider from 1 to 100, **Then** the visible line count changes smoothly from very fine (~981 lines, barely-there texture) through typical CRT density (~387 lines at Style=50) down to chunky authentic Apple-II bands (~150 lines at Style=100), with each ~10% slider step producing a similar perceptual change. +5. **Given** scanlines are enabled and "Use all monitors" is on, **When** the screensaver runs across multiple displays, **Then** each monitor's `RenderSystem` independently renders scanlines according to the same Style/Intensity values. +6. **Given** scanlines are enabled, **When** the user opens the Performance tab, **Then** there is no scanlines-related control on that tab and the quality preset slider has no effect on scanline appearance. +7. **Given** scanlines are enabled over a frame containing both bright streak pixels and dark background pixels, **When** the frame renders, **Then** scanline darkening is applied uniformly to every pixel (no source-luminance gating — dark areas show scanlines just as bright areas do). + +--- + +### User Story 4 - Custom Color Picker (Priority: P2) + +The user is not satisfied with Green, Blue, Red, Amber, or Cycle. They pick a new entry — **Custom…** — from the Color dropdown, which opens the standard Windows color-chooser dialog. The selected RGB drives the rain streak color and is persisted along with the 16 custom-palette slots from the chooser dialog so subsequent invocations remember both the chosen color and the user's palette. + +**Why this priority**: A frequently-requested customization that is genuinely small in scope: one enum variant, one combo entry, one platform call, and one registry value (plus the palette blob). Independent of dialog redesign in concept, but lives most naturally inside the new Visuals tab. + +**Independent Test**: Select Color → Custom…, pick a non-default color in the system dialog, confirm the preview rain renders in that color, close and reopen the dialog/screensaver, confirm the chosen color persists. + +**Acceptance Scenarios**: + +1. **Given** the Color dropdown is open, **When** the user inspects the list, **Then** the entries are Green, Blue, Red, Amber, Cycle, Custom… (in that order — Custom is appended at ordinal 5; the existing v1.4 ordinals 0..4 are preserved per FR-039 / SC-007). The selected-item display text is the same `Custom…` string used in the drop-list — there is no string mutation on selection (the ellipsis stays). +2. **Given** the user picks "Custom…", **When** the selection is committed, **Then** the standard Win32 color-chooser dialog opens pre-populated with the previously saved custom color (or bright green `RGB(0, 255, 0)` on first use). +3. **Given** the user picks a color in the chooser and clicks OK, **When** the chooser closes, **Then** the preview rain immediately renders in the chosen RGB and the Color combo shows "Custom" as the active selection. +4. **Given** the user picks a color in the chooser and clicks Cancel, **When** the chooser closes, **Then** the previous color scheme remains active and the combo selection reverts. +5. **Given** the user has previously chosen a custom color, **When** the screensaver next launches, **Then** the rain renders in that same custom color. +6. **Given** the user adjusts the chooser's 16 custom-color slots, **When** they reopen the color chooser later, **Then** those 16 slots are preserved. + +--- + +### User Story 5 - Removal of Fade-Timer Debug Overlay (Priority: P3) + +The fade-timer debug overlay was already orphaned (its hotkey was removed in an earlier release; only the dialog checkbox remained as a discoverable surface). With the dialog redesign removing that checkbox anyway, the entire feature is excised top-to-bottom — application state, settings, registry value, render code, shared state, render params, controller logic, .rc resource, and unit tests. + +**Why this priority**: Pure cleanup. No user-visible benefit other than a slightly tidier settings dialog (which is already accomplished by the tab redesign). Ship-ready last because it's lowest risk and lowest value. + +**Independent Test**: After implementation, grep the codebase for `FadeTimer`/`fadeTimer`/`ShowFadeTimers`/`m_showFadeTimers` — there should be zero references. All other unit tests still pass. + +**Acceptance Scenarios**: + +1. **Given** the codebase after removal, **When** a developer searches for fade-timer symbols, **Then** no production or test references exist (case-insensitive across all source files). +2. **Given** a user has the legacy `ShowFadeTimers` DWORD set in the registry, **When** the screensaver launches, **Then** the value is silently ignored and the screensaver behaves normally. +3. **Given** the full test suite is run, **When** unit tests complete, **Then** all 410+ remaining tests pass (the deleted fade-timer tests are removed, not failing). + +--- + +### User Story 6 - Intentional Visible Change On Upgrade (Priority: P3) + +Users upgrading from v1.3 or v1.4 will see CRT scanlines appear on first launch of v1.5 because the new Scanlines Enabled toggle defaults to ON. This is a deliberate departure from the v1.4 "no visible change on upgrade" guarantee — scanlines are the headline visual evolution of v1.5, worth showing every user by default. Anyone who dislikes the effect can disable it in one click via the Visuals tab. + +**Why this priority**: Not a code change in its own right, but a documented policy decision that affects user expectations and CHANGELOG copy. Low risk, low effort, but important to make explicit so reviewers and downstream packagers don't treat it as a regression. + +**Independent Test**: Take a registry hive captured from a clean v1.4 installation (no `ScanlinesEnabled` value present), launch v1.5 against it, confirm scanlines render visibly on first frame. Disable scanlines via the dialog, confirm `ScanlinesEnabled=0` is written, relaunch, confirm scanlines stay off. + +**Acceptance Scenarios**: + +1. **Given** a registry hive from a v1.3 or v1.4 install (no scanline values present), **When** v1.5 launches for the first time against it, **Then** scanlines render visibly (Enabled defaults to ON, Intensity defaults to 30, Style defaults to 50) and this change is explicitly called out as intentional in the v1.5 CHANGELOG entry. +2. **Given** an upgraded user dislikes the default scanlines, **When** they open the Visuals tab and toggle Scanlines Enabled OFF, **Then** scanlines disappear immediately and the OFF state persists across subsequent runs. + +--- + +### Edge Cases + +- **Live FPS unavailable**: First second after dialog open, before either FPS counter or PDH GPU monitor has produced a reading. Tab title MUST show `Performance (0 fps, 0% GPU)` rather than stale data from a prior session. The integer-`0` rendering is the documented placeholder behavior (per FR-012); the unavailable-data signal lives in the lock-free `m_hasPublishedFps` sentinel, not in the rendered string. +- **Cancel after editing custom-palette swatches**: Per FR-004 and FR-035, `CustomColorPalette` is unconditionally persisted at chooser-OK time. Clicking Cancel on the outer property sheet does NOT restore the previous palette — only the active `CustomColor` rolls back. +- **Re-selecting "Custom…" while Custom is already active**: The combo handler MUST force-open `ChooseColorW` even when no `CBN_SELCHANGE` fires (because the selection didn't actually change). The chooser is pre-populated with the current `CustomColor`. See FR-029. +- **Dismissal via X button or Alt+F4**: Identical to clicking Cancel — the snapshot is rolled back and any in-progress changes are discarded. The default dialog proc routes `WM_SYSCOMMAND SC_CLOSE` through `IDCANCEL`, so no explicit `WM_CLOSE` handler is needed. +- **GPU adapter switch while dialog is open**: User changes the GPU adapter combo, render contexts recreate. The live FPS readout should resume reporting from the recreated primary monitor context within ~1 second. +- **Scanlines at non-integer DPI scaling**: The shader's per-scanline mapping is computed from the actual output render-target height and the user's Style slider value; per-monitor DPI differences are handled implicitly because each `RenderSystem` knows its own output size. +- **Scanlines Style at extremes**: At Style=1 (~981 lines on a 1080p display), individual scanlines may be sub-pixel and produce a subtle uniform darkening or faint moiré rather than visible bands — this is acceptable and matches the "barely-there texture" intent. At Style=100 (~150 lines), bands are intentionally chunky and obviously non-physical, matching the Apple-II aesthetic. +- **Scanlines on mostly-dark content**: MatrixRain's typical frame is mostly black with bright streaks. Scanlines apply uniformly to every pixel regardless of source luminance (no gating), so dark areas of the frame still show scanline structure — this is the correct CRT behavior and is what users expect from a "scanlines" toggle. +- **Glow toggle off with quality preset on Custom**: The preset slider is disabled, but the custom passes/resolution/smoothness values still persist — toggling glow back on restores them without resetting to a preset. +- **Color picker cancelled with no prior custom color**: The combo reverts to the previously-selected built-in scheme; the default `RGB(0, 255, 0)` is NOT written to the registry until the user actually commits a custom color. +- **Property sheet tab title localization**: The Performance tab title is generated at runtime with FPS/GPU numbers interpolated; the format string must be templated, not concatenated, so a future translator can re-order or pluralize. +- **Multi-monitor with primary FPS dramatically different from secondaries**: The displayed FPS is the primary monitor's only. Secondaries may run at different rates (different refresh, different load) — this is acceptable and matches the per-monitor architecture from v1.4. +- **Old registry value `ShowFadeTimers` present**: Read and discard silently; do not warn, do not delete (some users back up registry hives, so a passive ignore is safer than active cleanup). + +## Requirements *(mandatory)* + +### Functional Requirements + +#### Dialog Structure +- **FR-001**: The settings UI MUST be a Windows property sheet (`PropertySheetW`) with exactly two pages, in this order: "Visuals" and "Performance (NN fps, NN% GPU)". +- **FR-002**: The property sheet MUST suppress the Apply button entirely (e.g., via `PSH_NOAPPLYNOW` and per-page handling such that `PSN_APPLY` does nothing distinct from live update). +- **FR-003**: Every control on either tab MUST apply its change live to the running preview without requiring an Apply or OK action. +- **FR-004**: Clicking **Cancel** MUST roll back every setting on both tabs (including all newly added settings: Glow Enabled, Scanlines Enabled, Scanlines Intensity, Scanlines Style, Custom Color) to the values they held when the dialog opened. The `CustomColorPalette` (16 chooser swatches) is explicitly **excluded** from the rollback set: palette edits are persisted unconditionally at chooser-OK time (see FR-035). +- **FR-004a**: The three dismissal paths have well-defined semantics: + - **OK** — Commits the (already-live) settings to the registry and closes. No additional propagation step is required because every per-control change has already been pushed into `SharedState` / `ApplicationState` via the live-preview path; the render thread is already showing the latest values. + - **Cancel** — Rolls back the snapshot via `ConfigDialogController::CancelLiveMode()`, posts a context rebuild only if a rebuild-worthy field (e.g., GPU adapter, multimon) changed, and closes. + - **X button / Alt+F4** — Identical to **Cancel**. No explicit `WM_CLOSE` handler is needed; the default dialog proc translates `WM_SYSCOMMAND SC_CLOSE` to `WM_COMMAND IDCANCEL`, which routes through `OnCancel(hDlg)` → `CancelLiveMode()`. + +#### Visuals Tab Contents (in order) +- **FR-005**: The Visuals tab MUST contain, in this top-to-bottom order: Density slider (0..100%), Speed slider (1..100%), Glow Intensity slider (1..200%), Glow Size slider (50..200%), Color combo box, Scanlines Enabled checkbox (standard `BS_AUTOCHECKBOX`, default checked), Scanlines Intensity slider (1..100%, default 30), Scanlines Style slider (1..100, default 50), Start In Fullscreen checkbox. +- **FR-006**: The Color combo box entries MUST be, in order: Green, Blue, Red, Amber, Cycle, Custom…. The first five preserve their v1.4 ordinals (0..4); `Custom` is appended at ordinal 5. Per FR-039 / SC-007 the existing five ordinals MUST remain byte-identical to the v1.4 baseline so existing registry hives reload to the same color. +- **FR-007**: The Glow Intensity slider's minimum value MUST be 1 (changed from 0); the legacy "0% (glow disabled)" special-case label MUST be removed. + +#### Performance Tab Contents (in order) +- **FR-008**: The Performance tab MUST contain, in this top-to-bottom order: GPU Adapter combo, Glow Enabled checkbox (standard `BS_AUTOCHECKBOX`, default checked), Quality Preset slider (Low/Medium/High/Custom), Glow Passes slider (1..4), Glow Resolution slider (Quarter/Half/Full), Glow Smoothness slider (Low/Medium/High), Use All Monitors checkbox (renamed from "Render on all monitors"), Show Statistics checkbox (renamed from "Show debug statistics"). + +#### Live Performance Readout +- **FR-009**: The Performance tab's title text MUST update at most once per second via a `WM_TIMER`-driven `PSM_SETTITLE` call. The title MUST use the exact format string `Performance (%u fps, %u%% GPU)` (after `printf` substitution, e.g. `Performance (60 fps, 45% GPU)`). The mixed case (`fps` lowercase, `GPU` uppercase) is intentional and matches Windows-ecosystem conventions (Task Manager uses lowercase `fps`; `GPU` is an acronym). The format string MUST live in the .rc as a string-table entry to permit future localization; the dialog code loads it once at init and reuses it for each timer tick. +- **FR-010**: The displayed FPS MUST be the primary monitor's render-thread FPS, exposed lock-free from each `MonitorRenderContext` (e.g., via `std::atomic`). +- **FR-011**: The displayed GPU% MUST come from the same PDH counter the runtime debug overlay uses. +- **FR-012**: When either FPS or GPU% data is not yet available, the corresponding integer field MUST be displayed as `0` (e.g. `Performance (0 fps, 0% GPU)` when neither has produced a reading; `Performance (60 fps, 0% GPU)` when only GPU is missing). The format string remains uniformly `%u`/`%u` — there is no separate placeholder token. +- **FR-013**: The property sheet header MUST be created with the flags required for runtime tab-title updates (`PSH_PROPTITLE` on the header, `PSP_USETITLE` on each page). + +#### Glow Enabled Toggle +- **FR-014**: The Glow Enabled control MUST be implemented as a standard `BS_AUTOCHECKBOX` (comctl32 v6). Keyboard navigation, focus rendering, and MSAA/UIA accessibility are provided automatically by the common controls and require no additional code. (The Win11/WinUI pill toggle visual is deferred to a future iteration — see the Deferred section.) +- **FR-015**: When Glow Enabled is OFF, the bloom pipeline MUST be fully bypassed in `RenderSystem` (not merely run with zero intensity). +- **FR-016**: When Glow Enabled is OFF, the following Visuals-tab controls MUST be visually disabled (`EnableWindow(FALSE)`): Glow Intensity slider, Glow Size slider, and their associated prompt labels, value labels, and info buttons. +- **FR-017**: When Glow Enabled is OFF, the following Performance-tab controls MUST be visually disabled: Glow Passes, Glow Resolution, Glow Smoothness, and Quality Preset sliders, plus their associated prompt labels, value labels, and info buttons. +- **FR-018**: Hovering any disabled glow control on the Visuals tab MUST show the tooltip text: `Glow is disabled on the performance tab.` +- **FR-019**: Hovering any disabled glow control on the Performance tab MUST show the tooltip text: `Glow is disabled.` +- **FR-020**: The Glow Enabled state MUST persist across runs in registry value `GlowEnabled` (DWORD, default 1). + +#### CRT Scanlines +- **FR-021**: A new post-process pass MUST be added to `RenderSystem` rendering after the bloom composite and before the final present. +- **FR-022**: The scanline shader MUST be ported from `..\Casso\Casso\Shaders\CRT\scanlines.hlsl`, preserving the upstream attribution comment (crt-pi by Davide Berra, MIT, SPDX header). +- **FR-023**: The shader's hardcoded `kNativeScanlines = 192.0` MUST be replaced with a line count uploaded per-frame from CPU via the constant buffer. The CPU MUST compute that line count from the user's Scanlines Style slider value (1..100) using the exponential mapping `lines = 1000 * pow(0.15, style / 100.0)`, yielding ~981 lines at Style=1, ~622 at Style=25, ~387 at Style=50, ~241 at Style=75, and ~150 at Style=100. The shader itself MUST remain mapless-simple: it multiplies `i.uv.y` by whatever line count CPU sent it. +- **FR-024**: Only the `g_scanlineIntensity` shader input (0..1 normalized from the 1..100 Scanlines Intensity slider) and the per-frame line count (from FR-023) MUST be wired to user-facing controls. Other constants in the shader's cbuffer (brightness, bloom, contrast, gamma, persistence, etc.) MUST be hardcoded to identity/no-op values. +- **FR-024a**: The shader's source-luminance gating from the upstream Casso port (`weight = saturate(lum * 4.0)` and the surrounding lerp) MUST be removed. Scanline darkening MUST apply uniformly to every output pixel regardless of source luminance. (Rationale: the upstream gating is tuned for Apple-II content that is mostly bright on dark backgrounds; MatrixRain's profile is the opposite, so gating would invert the expected "CRT scanlines on the whole screen" behavior.) +- **FR-025**: Each `RenderSystem` instance MUST execute its own scanline pass (per-monitor, mirroring the bloom model). +- **FR-026**: The scanlines feature MUST NOT be wired into the quality-preset system and MUST NOT add any control to the Performance tab. +- **FR-027**: Scanline state MUST persist across runs in three registry values: `ScanlinesEnabled` (DWORD, default 1), `ScanlinesIntensity` (DWORD percent 1..100, default 30), and `ScanlinesStyle` (DWORD 1..100, default 50). +- **FR-028**: A first-run installation (no prior scanline registry values) MUST have scanlines **enabled** by default (Enabled=ON, Intensity=30, Style=50) so that new users see the v1.5 CRT aesthetic immediately. The upgrade behavior from v1.3/v1.4 to v1.5 is therefore an **intentional** visible change: existing installations with no `ScanlinesEnabled` registry value will see scanlines render on first launch. This is a deliberate exception to the v1.4 "no visible change on upgrade" guarantee. The v1.5 CHANGELOG entry MUST prominently call this out and MUST mention the one-click disable path (Visuals tab → Scanlines Enabled → OFF). +- **FR-028a**: The Scanlines Enabled control MUST be implemented as a standard `BS_AUTOCHECKBOX`, matching the Glow Enabled checkbox (FR-014). (Like Glow Enabled, the Win11/WinUI pill toggle visual is deferred — see the Deferred section.) +- **FR-028b**: When Scanlines Enabled is OFF, the scanline post-process pass MUST be fully bypassed (not merely run with zero intensity), and the Scanlines Intensity and Scanlines Style sliders (with their prompt labels, value labels, and info buttons) MUST be visually disabled. +- **FR-028c**: The Scanlines Intensity slider's minimum value MUST be 1 (not 0), matching the Glow Intensity convention from FR-007. The Scanlines Enabled toggle owns the on/off semantics; a 0 value would be redundant. + +#### Custom Color Picker +- **FR-029**: Selecting "Custom…" in the Color combo MUST open the standard Win32 `ChooseColorW` dialog (commdlg.h). The chooser MUST open **every time** the user picks "Custom…", including when "Custom" is already the active selection (i.e., the user re-clicks the same item). Because `CBN_SELCHANGE` does not fire when the selection does not actually change, the combo handler MUST detect same-item re-click via a **subclass-based watcher**: subclass the combo, in the subclass proc check `CB_GETDROPPEDSTATE` on `WM_LBUTTONUP` and `WM_KEYUP(VK_RETURN)`, and force-open the chooser when the listbox was dropped-down and the Custom item is now the selection. +- **FR-030**: The chooser MUST be initialized with the previously-saved custom color, or `RGB(0, 255, 0)` on first use. +- **FR-031**: On chooser OK, the selected RGB MUST be persisted to registry value `CustomColor` (DWORD, RGB-packed) and immediately applied to the live preview. +- **FR-032**: On chooser Cancel, the previous color scheme MUST remain active; `CustomColor` MUST NOT be written. +- **FR-033**: The `ColorScheme` enum MUST gain a `Custom` variant; the chosen RGB MUST flow through `SharedState` to the render thread analogously to the existing `colorScheme` field. +- **FR-034**: When the active scheme is `Custom`, rain streaks MUST be rendered using the persisted `CustomColor` RGB rather than any of the four built-in palettes. +- **FR-035**: The chooser's 16 user-editable custom-color slots MUST be persisted as a new registry value `CustomColorPalette` (REG_BINARY, 16 × DWORD = 64 bytes), and restored on subsequent chooser opens. **Palette persistence is unconditional**: edits made inside `ChooseColorW` are written through to the registry at chooser-OK time and survive an outer property-sheet Cancel. Only the active `CustomColor` participates in the snapshot/rollback set (see FR-004). + +#### Fade-Timer Feature Removal +- **FR-036**: The following symbols and their definitions, declarations, callers, and tests MUST be removed entirely from the codebase: + - `ApplicationState::ToggleDebugFadeTimes`, `SetShowDebugFadeTimes`, `GetShowDebugFadeTimes`, and the corresponding change-callback registration. + - `ScreenSaverSettings::m_showFadeTimers` field and accessor(s). + - `RegistrySettingsProvider::VALUE_SHOW_FADE_TIMERS` constant and its read/write code paths. + - `RenderSystem::RenderDebugFadeTimes` and the call site that invokes it. + - `SharedState::showDebugFadeTimes` (both the live field and the snapshot field). + - `RenderParams::showDebugFadeTimes`. + - `ConfigDialogController::UpdateShowFadeTimers`. + - The "Show fade timers" checkbox in the .rc file (already removed by the tab redesign in FR-005/FR-008). + - All fade-timer test cases in `ConfigDialogControllerTests.cpp`, `ScreenSaverSettingsTests.cpp`, and `RegistrySettingsProviderTests.cpp`. +- **FR-037**: A legacy `ShowFadeTimers` registry value present from a prior installation MUST be silently ignored on read (not deleted, not warned about). + +#### Persistence / Migration +- **FR-038**: All new registry values (`GlowEnabled`, `ScanlinesEnabled`, `ScanlinesIntensity`, `ScanlinesStyle`, `CustomColor`, `CustomColorPalette`) MUST default to their specified defaults if missing on first read (`GlowEnabled`=1, `ScanlinesEnabled`=1, `ScanlinesIntensity`=30, `ScanlinesStyle`=50, `CustomColor`=`RGB(0,255,0)` on commit, `CustomColorPalette`=zeroed). +- **FR-039**: All existing v1.4 registry values MUST continue to be read and written identically — no migration, no format change, no compatibility shim required. + +#### Compatibility With Existing v1.4 Infrastructure +- **FR-040**: The quality-preset system (Low/Medium/High/Custom with drift behavior) MUST be preserved unchanged; scanlines are deliberately excluded from preset coverage. +- **FR-041**: The bloom pipeline's parametric knobs (passes/resolution/taps) MUST remain unchanged. +- **FR-042**: The first-run quality-preset heuristic MUST be preserved unchanged. +- **FR-043**: The v1.4 multi-monitor, GPU-adapter selection, device-loss recovery, frame-cap, and info-tip mechanisms MUST continue to function identically. +- **FR-044**: The existing live-preview / Cancel-rollback snapshot infrastructure in `ConfigDialogController` MUST be extended to cover every new setting added by this feature. + +### Key Entities + +- **Property Sheet**: The new top-level dialog container. Owns two child property pages. Owns a 1 Hz `WM_TIMER` that drives the Performance tab title update. Created modeless to remain compatible with the existing live-preview model. +- **Visuals Page**: Property page hosting all "what does it look like" controls, including the new Scanlines group and the new "Custom…" Color combo entry. +- **Performance Page**: Property page hosting all "how hard does it work the hardware" controls, including the new Glow Enabled toggle and the live FPS/GPU% in its title. +- **Glow Enabled Checkbox**: A standard `BS_AUTOCHECKBOX` (v1.5). Drives the bloom-pipeline bypass and the cross-tab enable/disable propagation. The Win11/WinUI pill toggle visual is deferred to a future iteration. +- **Scanline Shader**: A short HLSL pixel shader ported from Casso, post-bloom, pre-present, per-`RenderSystem`. Two CPU-fed inputs: intensity (0..1, normalized from the Scanlines Intensity slider) and line count (computed CPU-side from the Scanlines Style slider via `lines = 1000 * pow(0.15, style/100)`). The upstream source-luminance gating is removed so darkening applies uniformly. The shader stays mapless-simple — it just multiplies `i.uv.y` by the supplied line count. +- **Scanlines Enabled Checkbox**: A standard `BS_AUTOCHECKBOX` matching the Glow Enabled checkbox (FR-014), placed on the Visuals tab. Owns the scanline pass bypass and the enable/disable propagation to the Intensity and Style sliders. +- **Custom Color**: A packed RGB DWORD plus a 16-slot palette blob. Surfaced via a new `ColorScheme::Custom` enum variant. Threaded through `SharedState` to the render thread. +- **Live FPS Publisher**: A new `std::atomic` member on `MonitorRenderContext` written by the render thread per frame and read lock-free by the dialog thread for the Performance tab title. +- **Registry Schema (v1.5 additions)**: `GlowEnabled` (DWORD, default 1), `ScanlinesEnabled` (DWORD, default 1), `ScanlinesIntensity` (DWORD 1..100, default 30), `ScanlinesStyle` (DWORD 1..100, default 50), `CustomColor` (DWORD RGB), `CustomColorPalette` (REG_BINARY 64 bytes). Legacy `ShowFadeTimers` ignored on read. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: The settings dialog presents exactly two tabs ("Visuals" and "Performance (NN fps, NN% GPU)"), with no Apply button visible and zero fade-timer-related controls anywhere. +- **SC-002**: The Performance tab title reflects live FPS and GPU% changes within ≤1 second of those readings updating in the render thread / PDH counter. +- **SC-003**: With the Glow Enabled toggle OFF, every one of the six glow-related controls (Glow Intensity, Glow Size, Glow Passes, Glow Resolution, Glow Smoothness, Quality Preset) is visually disabled on its respective tab AND the rendered output shows zero bloom contribution (verifiable by frame capture or pixel sampling against a known glow source). +- **SC-004**: Hovering any disabled glow control surfaces the appropriate tab-specific tooltip text within the standard Win32 tooltip-show delay. +- **SC-005**: Selecting Color → Custom… opens the standard system color picker; on OK the rain renders in the chosen RGB on the next rendered frame; on Cancel the previous color scheme remains active and no registry write occurs. +- **SC-006**: Scanlines render visibly by default on a fresh install (Enabled=ON, Intensity=30, Style=50). With Scanlines Enabled OFF, the rendered output is bit-identical (or perceptually identical) to having no scanline pass. With Enabled ON, moving the Style slider across its 1..100 range smoothly varies line density from ~981 lines at the low end to ~150 lines at the high end (per the `lines = 1000 * pow(0.15, style/100)` curve), and scanline darkening applies uniformly to both bright streak pixels and dark background pixels with no source-luminance gating. +- **SC-007**: All v1.4 settings (Density, Speed, Glow Intensity, Glow Size, Color, Start In Fullscreen, GPU Adapter, Quality Preset, Glow Passes, Glow Resolution, Glow Smoothness, Use All Monitors, Show Statistics) persist across runs and apply live during dialog interaction with identical behavior to v1.4. +- **SC-008**: After fade-timer removal, the existing unit test suite (410+ tests excluding the deleted fade-timer tests) passes at 100%. +- **SC-009**: A registry hive containing a legacy `ShowFadeTimers` DWORD launches the v1.5 screensaver successfully with no warnings, errors, or behavior change. +- **SC-010**: All six new registry values default to their specified defaults (`GlowEnabled`=1, `ScanlinesEnabled`=1, `ScanlinesIntensity`=30, `ScanlinesStyle`=50, `CustomColor`=`RGB(0,255,0)` on commit, `CustomColorPalette`=zeroed) when missing on first read. +- **SC-011**: The dialog's OK / Cancel / X (and Alt+F4) dismissal paths have well-defined, tested semantics: **OK** commits live values to the registry; **Cancel**, **X**, and **Alt+F4** all roll back every setting on both tabs — including the five v1.5 rollback-eligible additions (Glow Enabled, Scanlines Enabled, Scanlines Intensity, Scanlines Style, Custom Color) — to its pre-dialog value with no residual side effect on the registry or live preview. `CustomColorPalette` is explicitly **outside** the rollback set (FR-004, FR-035) and is preserved across all three dismissal paths. +- **SC-012**: The scanlines feature adds no measurable cost to the quality-preset auto-selection heuristic and is not selectable via any preset (only via its dedicated controls in the Visuals tab). +- **SC-013**: An upgrade from a v1.3 or v1.4 install (registry hive with no `ScanlinesEnabled` value) launches v1.5 with scanlines visibly enabled on the first rendered frame, and the v1.5 CHANGELOG entry documents this intentional break from the v1.4 "no visible change on upgrade" guarantee along with the one-click disable path. + +## Deferred (Out of Scope for v1.5) + +- **Win11/WinUI-style pill toggle controls**: Both the Glow Enabled and Scanlines Enabled controls were initially specified as owner-drawn Win11-style toggles (rounded pill + sliding circle thumb). v1.5 ships them as standard `BS_AUTOCHECKBOX` controls to deliver the underlying functionality (bypass + cross-tab enable/disable propagation + persistence) without the visual polish. The pill toggle visual — including hover/focus animation, accent-color theming, and any required custom MSAA/UIA hooks — is deferred to a future iteration. + +## Assumptions + +- The user runs Windows 10 1809+ or Windows 11; `PropertySheetW` with runtime `PSM_SETTITLE` calls is supported reliably on these platforms (to be re-confirmed in research during the plan phase). +- The Casso peer repository (`..\Casso`) is present on the developer's machine at spec-write time, but the shader source will be **copied into** the MatrixRain repo at port time; no runtime dependency on Casso. +- The crt-pi MIT attribution in the shader source is sufficient for license compliance; LICENSE/THIRD_PARTY_NOTICES updates will be handled during plan/implementation, not in this spec. +- The 16-slot `CustomColorPalette` blob format matches `CHOOSECOLORW`'s `lpCustColors` layout (16 × COLORREF DWORDs) verbatim; no transformation needed. +- PDH GPU% counter behavior, FPS counter infrastructure, multi-monitor render context lifecycle, and live-preview / Cancel-rollback machinery from v1.4 are functioning correctly and merely need to be extended, not rewritten. +- "Primary monitor" for the FPS readout means whichever `MonitorRenderContext` corresponds to the OS primary display at the moment the timer fires; if that monitor is hot-removed, the next available context's FPS is acceptable. +- The Glow Enabled and Scanlines Enabled controls ship in v1.5 as standard `BS_AUTOCHECKBOX` controls; the Win11/WinUI pill toggle visual is deferred (see Deferred).
