v0.31.0

Highlights

• Added the xAI Responses provider and preserved complete web-search results across supported provider and tool paths.
• Simplified task-output observation and improved session task streaming, watchdog behavior, and control flow.
• Refined Control/Runtime boundaries while preserving participant turn identity and display metadata.
• Improved the interactive TUI welcome experience and status rendering, and hardened Windows runner process handling.

Verification

• Release SHA: b83bed1137b7b6cabeb1487188aa488a37ad87ae.
• Main quality workflow succeeded for the exact release SHA.
• Release workflow succeeded.
• Published six platform archives for Darwin, Linux, and Windows on amd64/arm64, plus checksums.txt.
• The Darwin arm64 archive checksum was verified, and the downloaded binary reports v0.31.0 with commit b83bed1137b7b6cabeb1487188aa488a37ad87ae.
• All seven @caelis/* npm packages report 0.31.0; the main package pins all six optional platform dependencies to 0.31.0.
• A clean npm installation reports v0.31.0 with the tagged commit.
• Agent SDK compatibility decision: compatible. The external-consumer smoke test passed through proxy.golang.org without a local replace, compiling every package in agent-sdk/supported-packages.txt.

v0.30.0

Highlights

• Consolidated Control and Session boundaries around the reusable Agent SDK and the Control-owned client, with safer lifecycle, replay, and handoff behavior.
• Added durable file-session barriers and recovery handling, including event-log rollback and platform-safe Windows persistence behavior.
• Hardened sandbox and skill filesystem boundaries while improving command/tool guidance, prompt budgeting, and streamed progress reporting.
• Improved Windows npm update handoff and release automation, including exact-SHA main quality gating before artifacts are published.
