 | ID | Requirement | State | Current evidence and gap |
 |----|-------------|-------|--------------------------|
-| G1 | Project create/open/resume, scene authoring, autosave/recovery, hierarchy, prefab, and asset integrity pass | Partial | Project/recovery/session/multi-scene/prefab implementations are documented in [project launcher](../../project-launcher.md), [session recovery](../../session-recovery.md), [multi-scene composition](../../multi-scene-composition.md), and [prefab authoring](../../prefab-authoring.md). Candidate-specific end-to-end reruns and the open asset-integrity work remain. |
+| G1 | Project create/open/resume, scene authoring, autosave/recovery, hierarchy, prefab, and asset integrity pass | Partial | Project/recovery/session/multi-scene/prefab implementations are documented in [project launcher](../../project-launcher.md), [session recovery](../../session-recovery.md), [multi-scene composition](../../multi-scene-composition.md), and [prefab authoring](../../prefab-authoring.md). Collaborative file safety `#49` and non-blocking native dialogs `#52` passed live acceptance. Candidate-specific end-to-end reruns remain. |
-| G2 | Brush, material, terrain, physics placement, animation, audio, navigation, PIE, and build/package samples pass | Fail | Animation, audio, navigation, and build foundations are implemented. Material/drag-drop tickets `#16`, `#18`, and `#51` remain open; terrain `#22`-`#24` and physics placement `#25` are not complete; brush acceptance `#37` remains open. Packaged testing is owner-deferred. |
+| G2 | Brush, material, terrain, physics placement, animation, audio, navigation, PIE, and build/package samples pass | Fail | Animation, audio, navigation, Material Library, targeted material drops, and build foundations are implemented. Renderer foundation `#51` remains open on deformed Solari geometry; terrain `#22`-`#24`, physics placement `#25`, and brush acceptance `#37` remain incomplete. Packaged testing is owner-deferred. |
 | G3 | Undo/redo/cancel invariants and helper cleanup cover every production mutation path | Partial | The reusable harness and current tool coverage are documented in [operator regression testing](../../operator-regression-testing.md). Gitea `#33` remains open for terrain-stroke and physics-settle fixtures after those tools exist. |
 | G4 | Representative project completes an eight-hour soak without unbounded memory/target growth or unrecoverable failure | Missing | No candidate soak log, resource timeline, failure ledger, or target-growth measurement exists. |
 | G5 | Cold start, scene open/save, asset refresh, common manipulation, and package-build budgets are documented and measured | Missing | Gitea `#34` is open; no ratified budgets or candidate measurement record exists. |
 | G6 | Headless content validation and CI are green from a clean checkout | Missing | [CI configuration](../../../../.github/workflows/ci.yml) exists and local source/headless checks have passed during feature work, but no clean-checkout candidate run is linked. The current Gitea server does not expose an Actions run endpoint for this repository. |
 | G7 | First-hour UX and recovery QA are signed off by someone other than the implementer | External | No independent sign-off exists. Gitea `#36` remains open; historical H1-H6 implementation-pass notes do not count. |
-| G8 | Known limitations have severity/workaround and no P0 blocker remains | Fail | Limitations are distributed across feature docs rather than one candidate ledger. Open P0 work includes `#16`, `#18`, `#32`, `#33`, `#35`, and `#51`; `#50` cannot close while a gate-relevant P0 remains. |
