Maintenance sweep update — 2026-03-20 (second run, ~11:35 UTC)

1. CI & Build health ✅

• Last 5 CI runs: 4 success, 1 failure (run 23334600244 — for loop sh syntax error in AR emulator script, already fixed by subsequent commit)
• All 4 non-AR samples build locally: model-viewer, gltf-camera, camera-manipulator, autopilot-demo
• AR screenshots from CI artifact (x86_64 Ubuntu): all 3 AR samples launch correctly — ARCore session initialises, "Move your phone slowly" state as expected for emulator
• Local non-AR screenshots: blank (Filament / swiftshader_indirect incompatibility on Apple Silicon) — this is a documented limitation, non-AR rendering screenshots need CI-side capture too

2. Issue triage ✅

• Only 1 open issue: this maintenance log
• PR Fix build sample on pull request #663 (hannesa2 — fix deprecated engine param in autopilot-demo + CI build all samples) — reviewed, approved, merged

3. Dependency updates ✅

Dependency	Current	Latest	Action
Filament	1.56.0	1.70.0	PR #667 opened — API break fixed, all 10 .filamat recompiled with matc v1.70.0
ARCore	1.53.0	1.53.0	✅ Up to date
Kotlin	2.1.21	2.3.20	PR #664 already open
AGP	8.11.1	9.2.0-alpha05	⏭️ Skip — alpha only

4. Code quality ✅

• ./gradlew :sceneview:lintDebug :arsceneview:lintDebug — BUILD SUCCESSFUL, 0 errors
• No new TODO/FIXME comments in last 24h

5. Sample improvements ✅

• model-viewer: Damaged Helmet scaled 0.25 → 1.0; Fox.glb (159KB, CC0, KhronosGroup glTF-Sample-Assets) added; FilterChip model picker row added at bottom — PR feat(samples): model-viewer — model picker + scale 1.0 #668 opened

6. MCP & llms.txt sync ✅

• No new public APIs since v3.1.1 — llms.txt unchanged
• MCP tests: 178/178 passing

7. Release decision ✅ — 3.1.2 proposed

• 6 meaningful commits since v3.1.1 (threshold: 5)
• Version bumped to 3.1.2 in all three modules
• CHANGELOG updated
• PR release: 3.1.2 #669 opened — release/3.1.2

PRs opened this run

#	Title	Status
#667	deps: bump Filament 1.56.0 → 1.70.0	Open — awaiting CI
#668	feat(samples): model-viewer model picker + scale 1.0	Open — awaiting CI
#669	release: 3.1.2	Open — awaiting CI

Next focus (2026-03-21)

• Merge release: 3.1.2 #669 (release 3.1.2) once CI passes, tag v3.1.2, publish to Maven Central
• Merge feat(samples): model-viewer — model picker + scale 1.0 #668 (model-viewer picker) and deps: bump Filament 1.56.0 → 1.70.0 #667 (Filament 1.70.0) once CI confirms clean
• Merge deps: bump Kotlin 2.1.21 → 2.3.20 #664 (Kotlin 2.3.20) — lowest risk, check for any coroutines API changes
• Add non-AR rendering screenshots to CI (x86_64 Ubuntu runner) — currently only captured locally where swiftshader gives blank frames on Apple Silicon
