4.4.0-beta.1 — astra cleanup preview

Beta for astra-cleanup PR #55, left unmerged for maintainer testing.

Changes

• Preserve command exit status and multiline/empty arguments through sandbox launch.
• Correct repeated writable mounts and safely render Git identity after reading sandbox configuration.
• Share the image/devcontainer installation sequence and gate releases on network enforcement and lint checks.
• Remove managed session/prompt hooks, legacy migration, handwritten typo hints, and the unused installation workspace setting.
• Run claude-sandbox verify directly through the sandbox without starting an AI session; update the docs to match.

Try it

uv tool install --force 'claude-sandbox==4.4.0b1'
claude-sandbox --recreate
claude-sandbox verify

Recreate the project container for this beta. Recreation drops container-local packages and forge logins; reapply those as needed. This release intentionally does not migrate old managed hook settings. The supported entry point remains the sandbox wrapper; direct invocation of an off-PATH vendor binary no longer triggers a managed hook.

The matching container image is ghcr.io/diamondlightsource/claude-sandbox:4.4.0-beta.1 for AMD64 and ARM64.
