Unity Repository Map

Primary role: Unity public-source discovery and authority map.

Repository Boundary

This locally authored map classifies the Unity-Technologies public organization snapshot captured at 2026-07-14T12:59:16Z. GitHub organization metadata and fully paginated public-repository enumeration both returned 804 repositories. The pre-projection capture had SHA-256 8291b471251053a8921651eb7c791d13a4794984b73670a51cdb1116deb49657; the tracked classified data/unity-technologies-public-repositories.json has SHA-256 b1438e6e8d438bab3eff2ff02f5a10e9374fdfb89b0581ffb936a42920fa2e05 and records 59 archived repositories, 356 forks, and 4 templates.

The map is a discovery index. A repository's presence, name, archive flag, or push date does not make it a current UI-system source.

Reusable Method

1. Enumerate every public repository through REST pagination and retain stable repository identity and snapshot time.
2. Record archive, fork, template, default branch, default-branch HEAD, README location, and tree-scan status.
3. Scan default-branch paths for UXML, USS, UI Toolkit/UIElements, uGUI/Canvas/EventSystem, IMGUI, HUD/menu, accessibility, localization, text, and input signals.
4. Counter-search descriptions and code paths so name-hidden candidates remain discoverable.
5. Assign every repository one relevance class and a disposition reason.
6. Deep-read only the authority subset, then pin each guidance claim to an exact revision and lifecycle context.

Snapshot Classification

UI relevance class	Repositories	Use
primary-ui-source	8	Unity UI system or explicit UI/example repository; refine lifecycle before use.
ui-adjacent-reference	5	Input, reference source, safe-area, calibration, or vector-graphics evidence that constrains a UI review.
runtime-ui-observation	23	Runtime UXML/USS or game/product UI implementation whose repository purpose is broader than UI.
legacy-ui-observation	72	Multiple uGUI, HUD, menu, or Canvas observations in repositories owned for another purpose.
editor-or-incidental-uitoolkit	21	UI Toolkit appears in editor tooling, inspectors, tests, or incidental help surfaces.
code-only-or-incidental-ui-signal	93	Sparse or ambiguous UI-like paths do not justify reference status.
historical-ui-source	1	Archived UIWidgets source retained as a separate historical framework.
excluded-misleading-name	1	A UI-like repository name does not match a general UI source after inspection.
excluded-fork-or-vendor-ui	90	Forked, mirrored, or vendored UI content is not automatically Unity-authored evidence.
no-ui-signal	490	No UI signal was located in metadata, topics, default-branch path scan, or counter-search.

Total: 804 repositories.

Authority And Lifecycle Disposition

Disposition	Pinned examples	How to use them
Current primary system/reference	uGUI's Unity 6000.3 Graphic.cs, UnityCsReference 6000.3.19f1 Panel.cs, and InputSystem InputSystemUIInputModule.cs	Use version-pinned component and integration architecture. UnityCsReference remains reference source rather than a package mirror.
Current explicit examples	BagelGame README, UI Toolkit manual code examples README, and accessibility sample README	BagelGame is a Unity 6.3 full-game UI Toolkit example; the manual repository contains documentation snippets; the accessibility sample is a Unity 2023.3 uGUI example. Keep each example's version and purpose attached.
Adjacent and current observation examples	EntityComponentSystemSamples README, XR Interaction Toolkit Examples README, and Unity Industry Viewer Template README	Use as implementation observations for their own product, ECS, XR, or industry-template context. They do not own the general UI-system contract.
Historical UI examples	UIElementsExamples README, Unite Copenhagen 2019 demo README, Unite LA turret demo README, and Unity Royale runtime demo README	Retain for UIElements/UI Toolkit technique lineage and their recorded Unity-era context. Unarchived status or a recent push does not revise their baseline.
Separate or excluded	Archived UIWidgets README, SimpleUIDemo README, and the 90 excluded-fork-or-vendor-ui rows	UIWidgets is a separate archived framework whose README points development elsewhere. SimpleUIDemo is a Project Tiny sample rather than a general UI reference. Fork and vendor content requires an independent provenance decision.

Completeness Limits

• The snapshot covers the public organization and each repository's observable default branch at capture time. It cannot observe private, deleted, transferred, or non-default-branch-only material.
• gen-playerid-stats and repotest123 returned tree-fetch errors; both reported repository size zero, leaving no default-branch content to inspect.
• Recursive trees were truncated for Graphics, google-dawn, llvm-project, mono, and runtime. No absence claim relies on those truncated trees.
• Broad GitHub Code Search has rate and result ceilings. It was used to counter-check candidates, not as the enumeration mechanism.
• Path and metadata signals identify candidates; they do not prove compilation, rendered behavior, lifecycle correctness, or current support.

Opinionated Guidance

• Start UI architecture research with the current primary sources, then use explicit examples for concrete version-scoped implementation evidence.
• Keep product samples, historical demos, separate frameworks, forks, mirrors, and incidental UI in distinct evidence lanes.
• Record repository owner, fork state, archive state, default-branch HEAD, README lifecycle statement, Unity/package version, authority class, and replacement path when one is named.
• Rebuild the inventory instead of editing counts by hand when the organization snapshot changes.

Platform-Specific Guidance

• Use the Unity 6000.3 branch and package context when applying the uGUI source linked here.
• Use the UnityCsReference 6000.3.19f1 SHA for this page's UI Toolkit architecture boundary, not the newer default-branch head captured by the inventory.
• Use InputSystem only for the input and UI integration behavior visible at its pinned SHA.
• Preserve each sample's recorded Unity version and purpose in any downstream Game UI reference record.

Unsupported Absolutes

• An unarchived repository is not proof of current guidance.
• A recent pushed_at value is not proof that a sample's Unity baseline changed.
• Repository ownership does not prove that every vendored or forked file is Unity-authored.
• A matching path or term does not prove that the repository is a UI-system source.
• This snapshot does not establish private or deleted repository history.

Verification Contract

Before citing a repository, resolve the exact default-branch or release SHA, read its lifecycle statement and version files, inspect the relevant source path, and assign one of the dispositions above. For a refreshed map, repeat public pagination, verify unique ids and full names, recompute archive/fork/template totals and all ten class totals, record tree exceptions, and publish the new inventory hash and capture timestamp together.

Source, License, And Attribution

• Inventory basis: public GitHub organization metadata, fully paginated public repository metadata, default-branch tree scans, and targeted counter-search captured on 2026-07-14T12:59:16Z.
• Inventory identity: 804 classified rows; pre-projection SHA-256 8291b471251053a8921651eb7c791d13a4794984b73670a51cdb1116deb49657; tracked JSON SHA-256 b1438e6e8d438bab3eff2ff02f5a10e9374fdfb89b0581ffb936a42920fa2e05; 59 archived repositories, 356 forks, and 4 templates.
• Repository licenses and reuse terms differ. Follow the pinned repository's own license before copying code or assets.
• Reuse form: locally authored discovery and authority map; repository metadata and links are evidence references, not imported implementation guidance.
