BUILDGOBLIN — FEATURE-TO-BUILD LAB Preview 0.1 | Windows x64 | Unity 6000.3.17f1 Start with GUIDE.html. It opens locally in your browser. WHAT THIS IS A small original firing-range project and an AI-assisted development exercise, with readable checks for a native Windows build. It is a worked example, not a complete game-studio agent, Unity certification or a guarantee about your game. FAST PATH 1. Extract the entire archive to a local folder. Do not run inside the ZIP. 2. In the source-only preview, first build using BUILD FROM SOURCE below and seal the build. Then open Build/BuildGoblin.exe to play. Click a target, reload, and pause. A source-only archive does not include an executable. 3. Open PowerShell in this folder and run: & ./tools/Verify-Build.ps1 -IncludeSeededFaults 4. Read Evidence/latest-summary.json and the associated run reports. 5. Open SampleProject using Unity 6000.3.17f1 for the guided code exercise. EXPECTED RESULT none: PASS pause: EXPECTED FAILURE DETECTED input: EXPECTED FAILURE DETECTED The intentionally broken scenarios are included to prove the checker notices the declared failures. They are not bugs in the reference scenario. REQUIREMENTS Windows x64. PowerShell 7 (tested on 7.6.9). Windows PowerShell 5.1 was not qualified. A graphics-capable machine that runs Unity 6 Windows players. Source editing/building requires your own activated Unity 6000.3.17f1 Editor and Windows build support. AI usage is optional and supplied by your own coding-agent account. No API subscription or credits are included. No Python or Node installation is needed for the buyer's verifier. SCRIPT TRUST Read tools/*.ps1 before running them. They hash the supplied Build folder, launch its player with synthetic-test arguments, and write Evidence next to it. They do not install services or change Windows security policy. If Windows blocks a downloaded script, review it before unblocking the individual trusted file (Properties > Unblock). Do not disable system-wide protections. BUILD FROM SOURCE Open SampleProject in the stated Editor. Use BuildGoblin > 2 - Build Windows sample. This regenerates the supplied sample scene; don't use that menu to overwrite an unrelated scene with unsaved work. Output is the sibling Build folder. In PowerShell run ./tools/Seal-Build.ps1, then Verify-Build.ps1. Sealing records the files you just built. Never reseal an unexplained modified download merely to silence a mismatch. LIMITS The 12 automated checks use synthetic commands through the sample's gameplay path. They do not certify physical keyboards/controllers, visual quality, networking, unrelated mechanics, or compatibility with another project. Hashes detect accidental changes relative to a manifest; a manifest packaged with files is not a cryptographic publisher signature or a defense against an attacker replacing both. Keep your trusted baseline separately. SUPPORT This is a pre-release validation build. No commercial support response-time promise is in force yet. Keep reports local; don't send full projects or keys. Before submitting a report, remove local usernames/paths from logs. Read LICENSES.txt for source and third-party terms.
