Mobile Chrome viewport fix, Java 21 Actions, Termux/proot APK bootstrap, chat fork RPC, project auto-naming, main merge

Daily Tech Digest — Mar 2, 2026

A concise recap of the last 24 hours of Codex work across web UI, Android tooling, and build automation.

Highlights

• Merged mobile UI work into main for codex-web-local and confirmed clean merge state.
• Fixed the mobile Chrome disappearing address bar issue by switching layout height to dynamic viewport units so the composer input stays visible.
• Unblocked a failing GitHub Actions build in termux-generator by pinning Java 21 in the workflow and rerunning the pipeline.
• Built and installed the gptos.intelligence.assistant Android APK (Termux Play variant), validated metadata, and clarified rootfs expectations for proot + SSH.
• Implemented chat forking via RPC (thread/fork) and exposed the action in the sidebar thread controls.
• Added a “Create project” button with auto-suggested Untitled Project N naming and first-available directory selection.
• Documented the asset-based bootstrap flow for Termux (prebuilt tar assets extracted on first run) and added a project .gitignore.

Details

• Web UI: The mobile viewport fix now uses dynamic viewport height to avoid Chrome address-bar collapse hiding the input. A separate merge brought the mobile refresh work into main.
• DevOps: GitHub Actions failures in the Termux generator were tied to Java runtime setup. Adding Java 21 to the workflow stabilized the build.
• Android: The Android assistant project is effectively a rebranded Termux Play build. Recent work covered APK builds, device installs, and debugging proot-distro bootstrap path rewriting plus mirror/TLS issues.
• Product UX: New project creation is quicker with an inline button and deterministic naming. Chat forking now routes through the RPC protocol for clean thread duplication.
