+# Changelog
+
+## 2026-03-18
+
+### Updated
+
+* The README and contributor guide to document the exact portable packaging command, both emitted artifacts (`artifacts/windhawk-custom-portable-installer.exe` and `artifacts/portable-build/windhawk-custom-portable.zip`), the `-SkipBuild` repack path, and the Visual Studio developer-shell fallback for native builds.
+* The New Mod Studio documentation to cover code-first and visual authoring modes, language-aware starter filtering, workflow bundles, CLI playbooks, and kickoff packets.
+* The README and contributor guide to document the verified two-step release flow (`vcvars64.bat` + `build.bat Release`, then `build_custom_portable.ps1`) and the new recent-session relaunch behavior in New Mod Studio.
+
+### Verified
+
+* `build.bat Release` from `src\windhawk` after priming a Visual Studio developer shell.
+* `powershell -ExecutionPolicy Bypass -File artifacts\installer-build\build_custom_portable.ps1`
+
+## 2026-03-17
+
+### Added
+
+* A richer mod install decision modal with community, targeting, freshness, and reviewability signals, plus direct jumps to the details, source, and changelog tabs before install.
+* A shared changelog viewer for Windhawk and mod release notes with release-summary cards and inline filtering.
+* Browse-mode discovery insight chips in Explore so high-signal mods surface their strengths without requiring a search query.
+* Guided Explore starting points that jump into fresh updates, community favorites, Taskbar, Explorer, Start menu, and Audio views.
+* Research-backed Explore missions that turn common Windows goals into compare-and-verify flows, with copyable AI briefs and an active mission workbench for comparing top candidate mods.
+* Additional Windows-surface discovery presets for Notifications, Window management, Input, and Appearance, backed by richer Windows shell search concepts.
+* Changelog controls for release scoping, a latest-only toggle, and copy-to-clipboard support for the visible notes.
+* A New Mod Studio flow with a real AI-ready starter template and AI prompt packs for ideation, scaffolding, review, and documentation.
+* A structured core mod starter and a structure-planning prompt so new mods can begin from a cleaner settings/runtime/helpers/hooks layout instead of one growing source block.
+* Additional mod creation templates for Explorer shell tweaks, window-behavior mods, and settings-first scaffolding.
+* A Chromium browser starter so Chrome-related mods can be created directly from the mod studio with a compile-safe browser UI scaffold.
+* Optional `.wh.py` Python mod authoring with a bundled `windhawk_py` helper module, generated `.wh.cpp` compatibility output, and mouse/keyboard automation helpers.
+* An editor cockpit redesign with live mod metadata, a one-click recommended compile action, an evidence board, a verification pack, a dynamic iteration plan, safer compile guidance, and copyable AI helper prompts for scaffold, review, scope explanation, test planning, docs, and release notes.
+* A Windows toolkit in the About page with OS/session diagnostics, Windows settings shortcuts, and Explorer actions for runtime paths.
+* Strategy cards and a disabled-first install path in the install modal, backed by focused heuristics for scope, freshness, and reviewability.
+* Local home quick-focus chips for local drafts, compile-needed mods, logging-enabled mods, and update-ready mods.
+* A scrollable editor cockpit shell with a pinned exit action so long mod sessions no longer hide the last controls off-screen.
+* Visible compile mode cards in the editor cockpit, replacing the hidden-first compile choice with explicit current and recommended states.
+* A contextual Windows bridge in the editor cockpit that infers shell surfaces from target processes and opens the matching Windows settings pages directly.
+* More Windows quick actions in the About page for Start, Notifications, Multitasking, and Colors.
+* More Windows customization routes in Explore for Context menu, Desktop, Alt+Tab, Virtual desktops, and Widgets, plus new missions for context-menu cleanup, desktop polish, and app switching.
+* More Windows quick actions in the About page for Background, Themes, Lock screen, and Clipboard.
+* A new Performance and AI settings section with balanced, responsive, and efficient workspace profiles, plus an NPU-aware AI acceleration preference.
+* Runtime-based local recommendation logic that can apply a suggested profile from the active machine's memory, NPU, and runtime-health signals.
+* Runtime diagnostics that now include total memory and detected NPU hardware for About and Settings.
+* More complex workflow settings for startup routing, Explore default sorting, editor assistance level, and Windows quick-action density, wired into Settings, About, Explore, and the editor cockpit.
+* New research-driven editor features: prompt-less AI explainers for APIs, Windows terms, and usage examples; a challenge board with counterquestions; a best-practice audit prompt; and a validation-feedback compile-recovery prompt.
+* A curated `force-process-accelerators` repository mod surfaced as a featured available install in the default online catalog.
+
+### Updated
+
+* The English locale with new mission-workbench, verification-pack, recommended-compile, and AI prompt-deck strings.
+* Contributor guidance for AI-assisted mod authoring and the new editor cockpit workflow.
+* The VS Code extension/editor bridge so compile, enable, and logging actions refresh the sidebar with current mod metadata.
+* Runtime diagnostics so the extension exposes Windows version/session details and reusable shell actions to the webview.
+* The README with the latest UI improvements and additional research references for code understanding, AI trust, and question-driven debugging.
+* The installed-mods overview so "needs attention" also surfaces debug-logging and compile-needed states, not just updates.
+* The editor workflow text so Shneiderman's overview-first guidance and the Whyline-style "what should I inspect next?" loop now show up directly in the sidebar rather than only in documentation.
+* Local UI preferences so performance profile and AI acceleration settings persist with the rest of the webview workspace state.
+* The README and contributor guidance to document the broader local workflow settings surface and the files that now depend on it.
+* The mod studio copy and docs to include Chromium/Chrome-focused authoring support and a browser UI prompt pack.
+* The mod studio flow so Python mode only offers starters that have real `.wh.py` implementations, avoiding template mismatches.
+* Local authoring preferences so stored language and source-extension choices stay aligned even if older or malformed state is loaded.
+* The research notes in the README to include newer work on AI challenge behavior, industrial code-review guidance, and validation-feedback repair loops.

+
+## Repository layout
+
+- `src/windhawk`: Native Windows engine and app solution (`windhawk.sln`).
+- `src/vscode-windhawk`: VS Code extension host integration.
+- `src/vscode-windhawk-ui`: React/Nx webview UI used by the extension.
+
+## Quick verification
+
+These commands are the fastest checks currently verified in this repository.
+
+### VS Code extension
+
+```powershell
+cd src\vscode-windhawk
+npm install --ignore-scripts --no-package-lock
+npx tsc -p . --noEmit
+npm run lint
+```
+
+### Webview UI
+
+```powershell
+cd src\vscode-windhawk-ui
+npm install --ignore-scripts --no-package-lock
+npx nx lint vscode-windhawk-ui
+npx nx lint vscode-windhawk-ui-e2e
+npx nx test vscode-windhawk-ui --runInBand
+npx tsc -p apps\vscode-windhawk-ui\tsconfig.app.json --noEmit
+npx nx build vscode-windhawk-ui
+```
+
+## Native build prerequisites
+
+The native solution is Windows-only and requires Visual Studio 2022 or the equivalent MSBuild + C++ build tools with a recent Windows SDK installed.
+
+Open `src/windhawk/windhawk.sln` in Visual Studio, or build it from a Visual Studio developer shell.
+
+### Native build shortcut
+
+If `src\windhawk\build.bat` doesn't find the expected Visual Studio path automatically, enter a Visual Studio developer command prompt first and then run:
+
+```powershell
+cd src\windhawk
+build.bat Release
+```
+
+That keeps the native build working even when the installed Visual Studio path differs from the hardcoded fallback inside `build.bat`.
+
+If you need to discover the current Visual Studio install path first, `vswhere` plus `vcvars64.bat` is the most reliable fallback:
+
+```powershell
+$vsPath = & "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" `
+  -latest -products * -property installationPath
+cmd /c "call `"$vsPath\VC\Auxiliary\Build\vcvars64.bat`" && cd /d src\windhawk && build.bat Release"
+```
+
+## Notes
+
+- The extension package includes native runtime dependencies. For lint and typecheck-only verification, `--ignore-scripts` avoids unnecessary rebuild steps.
+- If you add new automated checks, prefer commands that can run headlessly in CI.
+
+## Portable release packaging
+
+- Refresh the native binaries first. The packaging script does not rebuild `src\windhawk\Release` for you.
+- A verified native-build fallback is:
+
+```powershell
+$vsPath = & "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" `
+  -latest -products * -property installationPath
+cmd /c "call `"$vsPath\VC\Auxiliary\Build\vcvars64.bat`" && cd /d src\windhawk && build.bat Release"
+```
+
+- The supported packaging script is `artifacts/installer-build/build_custom_portable.ps1`.
+- Run it from the repository root with `powershell -ExecutionPolicy Bypass -File artifacts\installer-build\build_custom_portable.ps1`.
+- It expects a portable baseline install at `%LOCALAPPDATA%\Programs\Windhawk-Custom-Portable` and reads `windhawk.ini` from that location to determine the active engine path.
+- The script rebuilds the webview and extension by default, overlays the latest native binaries from `src/windhawk/Release`, rewrites the portable runtime config, and emits both `artifacts/windhawk-custom-portable-installer.exe` and `artifacts/portable-build/windhawk-custom-portable.zip`.
+- Use `-SkipBuild` only when you deliberately want to reuse the current webview and extension outputs while repackaging the portable payload.
+- If you change installer behavior, payload layout, or runtime config rewriting, keep `artifacts/installer-build/InstallerStub.cs` and `artifacts/installer-build/build_custom_portable.ps1` aligned so the release artifact and the packaged payload stay in sync.
+
+## AI-assisted mod authoring
+
+- The webview now includes a `New Mod Studio` flow with code-first and visual modes, language-aware starter filtering, a structured core starter, a standard starter, an AI-ready starter, focused starters for Explorer shell work, Chromium browser work, window behavior, and settings-first scaffolding, plus copyable prompt packs for ideation, structure planning, scaffolding, browser UI work, review, and documentation.
+- The same flow now exposes workflow bundles, recommended launch paths, CLI playbooks, and kickoff packets that combine the chosen starter, tools, prompts, and verification guidance into one copyable handoff.
+- The AI-ready starter lives at `src/vscode-windhawk/files/mod_template_ai_ready.wh.cpp` and is intentionally still a normal Windhawk template, not a separate runtime path.
+- Additional focused starters live beside it in `src/vscode-windhawk/files`. Keep them compile-safe, explanatory, and structurally legible: they should help contributors pick a mod shape quickly without pretending to be finished production mods.
+- Python-backed authoring now lives in `src/vscode-windhawk/files/mod_template_python.wh.py`, with the renderer in `src/vscode-windhawk/files/python/render_mod.py` and the helper module in `src/vscode-windhawk/files/python/windhawk_py`. Keep the generated `.wh.cpp` output valid because it is still the compile-time contract with Windhawk.
+- The create flow currently exposes the Python automation starter as the Python-backed template. If you add more `.wh.py` starters, update the modal starter filtering and tests so Python mode only offers templates that actually have a Python implementation.
+- If you add or rename starters, workflow bundles, or CLI playbooks, keep `NewModStudioModal.tsx`, `aiModStudio.ts`, `aiModStudio.spec.ts`, and `translation.json` aligned so the copy, filtering, and packet generation stay consistent.
+- Recent studio sessions are persisted in local UI settings and relaunch through stored editor launch context. If you change launch-context shape or recent-session behavior, keep `appUISettings.ts`, `appUISettings.spec.ts`, `NewModStudioModal.tsx`, and `translation.json` aligned.
+- Treat AI output as a draft. Contributors are still expected to verify hook targets, failure handling, compatibility notes, and manual test steps before shipping a mod or template change.
+
+## Editor cockpit workflow
+
+- The editor sidebar now depends on live `setEditedModDetails` metadata from the extension host. If you add editor-side actions that change compile state, logging, versioning, or target processes, keep that payload in sync.
+- The editor cockpit now uses an explicit scroll shell with a pinned footer exit action. Keep long-running or low-priority actions inside the scroll area and reserve the footer for persistent, high-value actions that must remain reachable.
+- Compile presets, process summarization, inferred Windows surfaces, contextual Windows quick actions, the evidence board, the iteration plan, and AI helper prompt generation live in `src/vscode-windhawk-ui/apps/vscode-windhawk-ui/src/app/sidebar/EditorModeControls.tsx` and `src/vscode-windhawk-ui/apps/vscode-windhawk-ui/src/app/sidebar/editorModeUtils.ts`. Update the paired tests when you change those flows.
+- The editor now also derives a recommended compile profile and a verification pack from the current draft state. If you retune those heuristics, update the utility tests rather than burying the behavior inside the component.
+- The sidebar intentionally refreshes details after compile, enable, and logging actions so the authoring UI reflects the latest runtime state instead of stale local assumptions.
+- The newer AI flows are intentionally heuristic-backed. If you change the prompt deck or evidence cards, keep `editorModeUtils.spec.ts` aligned so trust and verification guidance do not silently drift.
+- The latest editor AI additions are research-driven: prompt-less explainers, a challenge board, best-practice audit prompts, and validation-feedback recovery prompts. Keep those grouped and legible so the cockpit stays actionable rather than turning into an undifferentiated prompt dump.
+
+## Windows runtime toolkit
+
+- `AppRuntimeDiagnostics` is shared between the extension host and the webview. If you add or rename Windows environment fields, update both `src/vscode-windhawk/src/webviewIPCMessages.ts` and `src/vscode-windhawk-ui/apps/vscode-windhawk-ui/src/app/webviewIPCMessages.ts` together.
+- Runtime diagnostics now include memory and simple NPU detection in addition to Windows version/session data. Keep `RuntimeDiagnosticsUtils` fast and defensive because these values are fetched as part of normal settings/about flows.
+- The About page and the editor cockpit now use `openExternal` and `openPath` IPC actions for Windows settings deep links and Explorer path launches. Reuse those actions instead of hardcoding shell behavior inside React components.
+- Windows-surface discovery lives in `src/vscode-windhawk-ui/apps/vscode-windhawk-ui/src/app/panel/modDiscovery.ts` and `ModsBrowserOnline.tsx`. When you add new Windows areas, update the concept vocabulary, preset cards, mission coverage, and `modDiscovery.spec.ts` together so search, browse insights, and preset counts stay aligned.
+- Research missions also live off the discovery layer. If you add or retune a mission, keep the query, follow-up queries, workbench candidate summaries, verification checks, and mission-brief output coherent so Explore still encourages compare-and-verify behavior instead of one-click blind installs.
+
+## Local performance preferences
+
+- Local workspace behavior is coordinated through `src/vscode-windhawk-ui/apps/vscode-windhawk-ui/src/app/appUISettings.ts`. If you add new local UI switches, update the normalization, defaults, persistence tests, and any runtime-based recommendation logic together.
+- The new Performance and AI settings section reads `runtimeDiagnostics` from `getAppSettings`. If you change those diagnostics, keep the recommendation copy and the About page summary aligned so the same machine state does not produce contradictory guidance.
+- Workflow-level settings now also drive the startup route, Explore's empty-query sort, the editor cockpit assistance level, and Windows quick-action density in About/editor surfaces. Keep `Panel.tsx`, `ModsBrowserOnline.tsx`, `About.tsx`, and `EditorModeControls.tsx` aligned when you add or rename those controls.
+
+## Install and home heuristics
+
+- Install decision heuristics live in `src/vscode-windhawk-ui/apps/vscode-windhawk-ui/src/app/panel/installDecisionUtils.ts`. If you change install guidance, keep the recommendation cards and checklist logic aligned so the modal does not suggest an action that contradicts its own signals.
+- The install modal now supports a disabled-first install path through the existing install IPC. If you change the install request payload shape, make sure the not-installed and update flows still preserve the optional `disabled` flag.
+- Curated repository mods are merged into the normal online catalog in the extension host. Keep their metadata, source URLs, and install expectations aligned so featured defaults such as `force-process-accelerators` behave like first-class available mods.
+- Local home insights live in `src/vscode-windhawk-ui/apps/vscode-windhawk-ui/src/app/panel/localModsInsights.ts`. Update the paired tests when you retune what counts as "needs attention", "needs compile", or "logging enabled" so quick-focus chips and overview counts remain intentional.

 For technical details about the global injection and hooking method that is used, refer to the following blog post: [Implementing Global Injection and Hooking in Windows](https://m417z.com/Implementing-Global-Injection-and-Hooking-in-Windows/).
 
+### Runtime storage contract
+
+The most important runtime invariant for a working build is that the app, the embedded extension, and the engine all resolve to the same storage backend.
+
+* `windhawk.ini` selects the install mode and points the app and extension to the active app-data root, engine folder, compiler folder, and UI runtime.
+* `Engine\<version>\engine.ini` must resolve to the matching engine app-data root and, for installed mode, the matching registry subtree.
+* If those files disagree, the UI can still show mods as installed while the injected engine loads a different storage location and the mods never activate.
+
+The current fork now exposes runtime diagnostics in the About page, surfaces storage mismatches on the Home page, and includes a repair action that rewrites the engine config to match the active install.

 A simple way to get started is by extracting the portable version of Windhawk with the official installer, building the part of Windhawk that you want to modify, and then replacing the corresponding files in the portable version with the newly built files.
 
+## Development
+
+Contributor setup, verified validation commands, and native build prerequisites are documented in [CONTRIBUTING.md](CONTRIBUTING.md).
+
+## Portable installer build
+
+This fork includes a portable packaging flow that bundles the rebuilt native binaries, the VS Code extension, and the React webview into a custom installer.
+
+Typical packaging flow:
+
+1. Refresh the native Release binaries:
+
+```powershell
+$vsPath = & "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" `
+  -latest -products * -property installationPath
+cmd /c "call `"$vsPath\VC\Auxiliary\Build\vcvars64.bat`" && cd /d src\windhawk && build.bat Release"
+```
+
+2. Run the packaging script from the repository root. It rebuilds the webview and extension by default before staging the portable payload:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File artifacts\installer-build\build_custom_portable.ps1
+```
+
+If `src\windhawk\build.bat` doesn't detect the local Visual Studio installation automatically, a Visual Studio developer shell or the explicit `vswhere` + `vcvars64.bat` sequence above is the supported fallback.
+
+The script produces `artifacts/windhawk-custom-portable-installer.exe` and `artifacts/portable-build/windhawk-custom-portable.zip`, refreshes the staged portable payload used by the installer stub, and expects a portable Windhawk baseline at `%LOCALAPPDATA%\Programs\Windhawk-Custom-Portable`. Use `-SkipBuild` only when you intentionally want to reuse the current webview and extension outputs.
+
+## UI preview
+
+The React webview lives in `src/vscode-windhawk-ui` and can be iterated on independently from the native C++ binaries.
+
+Typical local preview workflow:
+
+1. `cd src/vscode-windhawk-ui`
+2. `npm install --ignore-scripts --no-package-lock`
+3. `npx nx build vscode-windhawk-ui`
+4. Serve `dist/apps/vscode-windhawk-ui` with a static file server, for example:
+   `python -m http.server 4200 --directory dist/apps/vscode-windhawk-ui`
+
+Then open `http://127.0.0.1:4200/`.
+
+## Recent UI improvements
+
+The webview UI now includes:
+
+* smarter mod discovery with typo recovery, query broadening, and refinement suggestions
+* a redesigned settings experience with persistent local workspace controls for density, startup page, Explore default sorting, editor assistance level, Windows quick-action density, wide layout, reduced motion, and performance tuning
+* an expanded About page with current workspace status, runtime diagnostics, path inspection, repair actions, and quicker access to key project resources
+* a richer installed-mods home view with a fast overview strip and an early warning when the engine storage backend diverges from the UI backend
+* a research-informed install decision modal with scope/freshness/community signals and one-click review actions for details, source, and changelog tabs
+* strategy-based install guidance with a disabled-first path for broad-scope or lower-reviewability mods, plus a short pre-install checklist derived from scope and freshness
+* a shared changelog explorer with release-summary cards and inline filtering in both the About page and per-mod changelog views
+* browse-mode insight chips in Explore so fresh, popular, and focused mods stand out even before typing a query
+* guided Explore starting points that jump straight into fresh updates, community favorites, or focused areas such as Taskbar, Explorer, Start menu, and Audio
+* research-backed Explore missions that turn common Windows goals into compare-and-verify flows, with copyable AI comparison briefs and an active mission workbench for top-candidate comparison
+* broader Windows-surface discovery presets for notifications, window management, input, and appearance so the catalog is easier to navigate by the Windows area you want to change
+* more Windows customization entry points in Explore for context menus, the desktop surface, Alt+Tab, virtual desktops, and widgets so it is easier to start from the part of Windows you actually want to change
+* richer changelog tooling with release scoping, a latest-only toggle, and copy-to-clipboard support for the currently visible notes
+* a new mod studio that promotes AI-assisted authoring with code-first and visual creation modes, language-aware C++ and Python starter filtering, a structured core starter, an AI-ready starter template, focused starters for Explorer shell work, Chromium/Chrome browser mods, window behavior mods, settings-first experiments, and optional `.wh.py` Python automation authoring that renders back to compatible `.wh.cpp`
+* workflow bundles inside the mod studio with recommended launch paths, copyable kickoff packets, and CLI playbooks that combine the chosen starter, prompt packs, and verification checklist into one handoff
+* persistent recent studio sessions in New Mod Studio so starters, visual presets, and workflow bundles can be relaunched with the same launch brief, packet, authoring language, and studio mode
+* a redesigned editor cockpit with a real scroll shell, a pinned exit action, live mod metadata, visible compile mode cards, a one-click recommended compile action, an evidence board, a verification pack, a dynamic iteration plan, and copyable AI helper prompts for scope analysis, test planning, release notes, and review
+* contextual Windows integration inside the editor cockpit, including inferred shell-surface tags and one-click deep links into the Windows settings pages that match the current mod's target processes
+* newer research-driven editor innovations including prompt-less AI explainers for APIs, Windows terms, and usage examples, a visible challenge board that pushes the draft with counterquestions instead of agreement, a best-practice audit prompt, and a validation-feedback recovery prompt for failed builds
+* a Windows toolkit on the About page with live OS/session diagnostics, expanded quick links into key Windows settings surfaces such as Start, Notifications, Multitasking, Colors, Background, Themes, Lock screen, Clipboard, and one-click opening of Windhawk runtime paths in Explorer
+* local home quick-focus chips for drafts, compile-needed mods, logging-enabled mods, and pending updates so maintenance work is easier to batch
+* a new Performance and AI settings section with runtime-based profile recommendations, NPU-aware acceleration preferences, and coordinated local UI presets for balanced, responsive, or efficient workspaces
+* richer runtime diagnostics that now surface system memory and detected NPU hardware so local recommendations and Windows troubleshooting are grounded in the active machine
+* a curated `force-process-accelerators` repository mod surfaced as a featured available install so process CPU/GPU/NPU preference tuning is easier to discover from the default catalog
+
+## Research-informed UX improvements
+
+These interaction changes are intentionally grounded in a small set of papers that map well to Windhawk's mod-install and release-review workflows.
+
+* [Crying Wolf: An Empirical Study of SSL Warning Effectiveness](https://www.usenix.org/conference/usenixsecurity09/technical-sessions/presentation/crying-wolf-empirical-study-ssl) motivated a more concrete install warning with supporting context and clear review paths instead of a single generic caution block.
+* [An Empirical Study of Release Note Production and Usage in Practice](https://www.microsoft.com/en-us/research/publication/an-empirical-study-of-release-note-production-and-usage-in-practice/) informed the release-summary cards and searchable changelog view so the most actionable updates are visible before reading the full Markdown stream.
+* [The Eyes Have It: A Task by Data Type Taxonomy for Information Visualizations](https://www.cs.umd.edu/users/ben/papers/Shneiderman1996eyes.pdf) continues to inform the "overview first, zoom and filter, then details on demand" structure used across Explore, changelog, and the editor cockpit's visible mode cards and status surfaces.
+* [Using an LLM to Help With Code Understanding](https://research.google/pubs/using-an-llm-to-help-with-code-understanding/) pushed the editor cockpit toward prompt-light, in-IDE requests such as scope explanation, API understanding, and test-plan generation instead of one generic AI action.
+* [Identifying the Factors that Influence Trust in AI Code Completion](https://research.google/pubs/identifying-the-factors-that-influence-trust-in-ai-code-completion/) motivated the evidence board, visible compile mode states, and safer compile recommendations so AI assistance is paired with explicit trust signals and verification steps.
+* [Source-level Debugging with the Whyline](https://faculty.washington.edu/ajko/papers/Ko2008SourceLevelDebugging.pdf) informed the new mission and editor flows that foreground "why this candidate?", "what Windows surface should I check?", and "what should I verify next?" instead of forcing users to build those questions manually.
+* [AI-assisted Assessment of Coding Practices in Industrial Code Review](https://research.google/pubs/ai-assisted-assessment-of-coding-practices-in-industrial-code-review/) motivated the new best-practice audit prompt so contributors can ask for language-aware C++ and Windows review comments instead of only generic summaries.
+* [AI Should Challenge, Not Obey](https://www.microsoft.com/en-us/research/publication/ai-should-challenge-not-obey/) directly informed the editor challenge board and counterexample-hunt prompts so the assistant can question assumptions rather than merely comply.
+* [A Case Study of LLM for Automated Vulnerability Repair: Assessing Impact of Reasoning and Patch Validation Feedback](https://arxiv.org/abs/2405.15690) pushed the new compile-recovery prompt toward smaller, validation-driven iteration loops after build failures instead of broader speculative rewrites.
+
+## Research-informed reliability
+
+The new diagnostics and repair flow is based on a narrow, reliability-focused interpretation of configuration research rather than more invasive runtime behavior changes.
+
+* [PeerPressure: Using Peer Configuration to Troubleshoot Systems Automatically](https://www.usenix.org/legacy/events/osdi04/tech/full_papers/wang/wang_html/) motivated the idea of treating configuration mismatches as first-class failures instead of as vague runtime symptoms.
+* [Strider: A Black-box, State-based Approach to Change and Configuration Management and Support](https://www.microsoft.com/en-us/research/publication/strider-a-black-box-state-based-approach-to-change-and-configuration-management-and-support/) informed the emphasis on comparing observed state with expected state before attempting repair.
+* [Automatically Generating Predicates and Solutions for Configuration Troubleshooting](https://www.usenix.org/conference/atc10/automatically-generating-predicates-and-solutions-configuration-troubleshooting) reinforced the direction of pairing diagnostics with concrete, low-friction fixes instead of only presenting raw paths and flags.
+* [The Eyes Have It: A Task by Data Type Taxonomy for Information Visualizations](https://www.cs.umd.edu/users/ben/papers/Shneiderman1996eyes.pdf) informed the UI structure: overview first, then diagnostic details on demand.
+
+## Advanced Research Features (2025-2026)
+
+This research fork of Windhawk implements state-of-the-art stealth and evasion techniques:
+
+### Injection & Stealth
+* **Indirect Syscalls**: Bypassing EDR/AV hooks by dynamically resolving SSNs and using legitimate `syscall` instructions in `ntdll`.
+* **Phantom Thread Pool Injection**: Hijacking existing Windows Thread Pool worker threads via APCs to avoid `NtCreateThreadEx` detection.
+* **Module Stomping**: Hiding engine shellcode within the memory region of signed, file-backed Microsoft DLLs (e.g., `xpsprint.dll`).
+* **ETW Evasion**: Surgical suppression of `EtwEventWrite` to blind telemetry during sensitive engine operations.
+
+### Hooking & Integrity
+* **HWBP Hooking Engine**: Hardware Breakpoint-based hooking using CPU Debug Registers (DR0-DR3), ensuring zero bytes of target code are modified.
+* **Injection Integrity Guard**: VEH-based `PAGE_GUARD` monitoring to detect and alert on unauthorized tampering of engine trampolines.
+* **Call Stack Spoofing**: Synthetic ROP chain construction to hide the engine's origin during critical OS API calls.
+
+### Performance & API
+* **Mod Sandbox**: Per-mod resource limits (CPU rate, Memory MB, Max Handles) via thread-level throttling and background priority.
+* **Priority-Based Filtering**: Orchestrated injection flow with configurable priorities (`Deferred`, `Low`, `Normal`, `High`, `Critical`).
+* **Extended Mods API**: Native support for `Wh_GetProcessInfo`, `Wh_RegisterCallback` (async events), and `Wh_GetSystemInfo`.

+# Your AI-Assisted Mod
+Use this starter when you want an AI assistant to help with ideation,
+refactoring, documentation, or test planning while you stay in control of the
+actual hook targets and safety decisions.
+
+## AI collaboration brief
+Before asking an AI tool for help, give it:
+- The target process and why it is the right process.
+- The user-visible behavior you want to change.
+- The Windows APIs, exports, or messages you suspect are involved.
+- Safety constraints, fallback behavior, and any settings you want exposed.
+- The exact errors, logs, or manual test results you already observed.
+
+## Structure brief
+Tell the AI to preserve the current section layout:
+- `ModSettings` for user-configurable values.
+- `RuntimeState` for runtime-only state.
+- Hook callbacks for the behavior you are changing.
+- Helpers such as settings loading and hook installation.
+- Lifecycle callbacks for init, uninit, and settings changes.
+
+## Suggested prompt
+Paste something like this into your AI assistant:
+
+```text
+Help me write a Windhawk mod in C++.
+Target process: mspaint.exe
+Goal: Force Paint to use one color and optionally block file opening.
+Constraints:
+- Keep the metadata, readme, and settings blocks valid for Windhawk.
+- Preserve the section layout for settings, runtime state, hook callbacks,
+  helpers, and lifecycle callbacks.
+- Explain why each hook target is appropriate.
+- Minimize risk to unrelated behavior.
+- Provide manual test steps and edge cases.
+Output:
+- Updated source code
+- A brief explanation of each hook
+- A checklist of what I still need to verify myself
+```
+
+## Human verification checklist
+- Confirm that the target process is correct.
+- Confirm that each hook target exists and is called in the scenario you care
+  about.
+- Compile and test the mod with logging enabled before widening its scope.
+- Review any AI-generated code for crashes, blocking calls, or unsafe pointer
+  usage.
+- Document the expected behavior and recovery path if the mod fails.
+
+## Manual test plan
+- Compile the mod with the button on the left or with Ctrl+B.
+- Run Microsoft Paint from the Start menu or by launching `mspaint.exe`.
+- Draw something and confirm that the orange color is always used.
+- Try opening a file and confirm that it is blocked when the setting is
+  enabled.

+Use this starter when the target is Chrome or another Chromium-family browser
+surface such as the tab strip, title bar, browser commands, or window-level UI.
+
+## Good first questions
+- Is the behavior owned by the browser chrome, not by page content?
+- Which browser window class, command, message, or accelerator is closest to the
+  user-visible change you want?
+- What adjacent browser flow should remain unchanged if the hook target is right?
+
+## Safe first iteration
+- Keep the process scope on `chrome.exe` first.
+- Compile with logging enabled for the first run.
+- Open one browser window and confirm the foreground browser window details in
+  the log before adding a hook.
+- Only then widen to other Chromium-family executables if you have evidence the
+  same surface is shared.

+- You can lock down the config structure before adding risky code.
+- It is easier to review names, defaults, and migration risks early.

+- Finalize the settings shape.
+- Add logging around how each setting changes the intended behavior.
+- Only then begin tracing the APIs that should consume those settings.

+# Your Structured Mod
+Use this starter when you want the mod's code layout to stay readable as the
+idea grows. The template intentionally separates configuration, runtime state,
+helpers, planned hook setup, and lifecycle callbacks.
+
+## Suggested build order
+1. Confirm the target process is correct.
+2. Run the dry-run template with logging enabled.
+3. Inspect the current window/process state in the logs.
+4. Replace `InitializePlannedHooks` with the smallest useful hook setup.
+5. Only then widen scope or add more settings.
+
+## Section guide
+- `ModSettings`: values loaded from the Windhawk settings block.
+- `RuntimeState`: state derived while the mod is running.
+- Helpers: reusable diagnostics and plan-summary functions.
+- Hook setup: the place to install your real hooks once the target is proven.
+- Lifecycle callbacks: `Wh_ModInit`, `Wh_ModUninit`, and
+  `Wh_ModSettingsChanged`.

+# Your Window Behavior Mod
+Use this starter for per-app behavior such as caption tweaks, visibility rules,
+window styles, minimum sizes, snap behavior, or placement changes.
+
+## Typical APIs to inspect
+- `ShowWindow`
+- `SetWindowPos`
+- `CreateWindowExW`
+- `SetWindowLongPtrW`
+- `DwmSetWindowAttribute`
+
+## Safe first iteration
+- Keep the scope on one application first.
+- Log the foreground window class and title before changing behavior.
+- Avoid widening to `*` until you know exactly which windows should be affected.
+
+## References
+Check out the documentation
+[here](https://github.com/ramensoftware/windhawk/wiki/Creating-a-new-mod).
