+Decision date:
+
+- `2026-05-01`
+
+Current licensing judgment:
+
+- executable/manual surface is locally possessed
+- source code is not locally possessed
+- direct donor use is not cleared
+- preserve upstream authorship attribution to `Andrey Astrelin`
+
+Source basis:
+
+- `C:\HyperTwist\superliminal.com\superliminal.com\andrey\mht633\index.html`

+- `C:\HyperTwist\superliminal.com\superliminal.com\andrey\mht633\logs\*`
+
+Important provenance note:
+
+- the retained download archive currently exposes runtime binaries only:
+  - `m3dht633.exe`
+  - bundled DirectX DLLs
+- a quick archive inspection did not surface source code or a bundled top-level `LICENSE`, `COPYING`, or equivalent file
+- this makes `Magic Hyperbolic Tile {6,3,3}` a behavior-spec / clean-room reverse-engineering candidate rather than a direct-source donor
+
+Approved working posture:
+
+- retain the lane as executable/manual/source-behavior reference only
+- do not pretend local source exists when it does not
+- if HyperTwist pursues implementation, use:
+  - the manual pages
+  - observed runtime behavior
+  - persisted solve logs
+  - visible UI/control semantics
+  as clean-room input for a behavioral spec

+### `loopover`
+
+Decision date:
+
+- `2026-05-01`
+
+Current licensing judgment:
+
+- explicit `MIT`
+- local source zip is possessed
+- project governance choice is still clean-room implementation
+
+Source basis:
+
+- `C:\HyperTwist\zippedreposource\loopover-master.zip`
+- bundled `loopover-master/LICENSE`
+- bundled `loopover-master/README.md`
+
+Practical obligations:
+
+- preserve the upstream `MIT` license text
+- preserve the upstream copyright notice:
+  - `Copyright (c) 2020 Janis Pritzkau`
+
+Approved working posture:
+
+- even though the license is permissive, keep this lane in clean-room implementation by current HyperTwist governance choice
+- use the local source only for the clean-room donor/spec lane, not as a quiet direct transplant

+- preserve both upstream license texts or the effective chosen path
+- preserve upstream copyright attribution:

+- do not misclassify it as unclear-license or missing-license

+### `Sonicpineapple/Green`
+
+Decision date:

+- `2026-05-01`
+
+Current licensing judgment:

+- no explicit top-level license text surfaced in the currently inspected local zip
+- do not treat as a direct donor

+
+Source basis:
+
+- `C:\HyperTwist\zippedreposource\Green-master.zip`
+- bundled `Green-master/Cargo.toml`
+- bundled `Green-master/README.md`
+
+Important provenance note:
+
+- the local zip exposes a manifest and README, but no bundled top-level `LICENSE`, `COPYING`, or equivalent file surfaced in the current inspection
+- current HyperTwist posture is governed by caution, not by assuming implied permission from a public repo
+
+Approved working posture:
+
+- keep this lane in clean-room implementation
+- do not use directly unless the authoritative upstream license is later captured explicitly
