v0.80.9

🌟 Release Highlights

This release focuses on reliability and correctness — squashing noisy error conditions in the MCP server and agentic workflows, hardening security, and keeping the observability pipeline complete.

🐛 Bug Fixes & Improvements

• MCP stdio error handling — handleMessage now correctly serialises plain-object throws (not just Error instances), eliminating the cryptic -32603 [object Object] failures that blocked submit_pull_request_review on the stdio transport path. (#40715)

• Issue Monster noise reduction — Agent-availability errors ("copilot coding agent is not available for this repository") are now treated as transient and silently skipped, so the issue tracker is no longer spammed with failure issues on every 30-minute poll cycle. (#40716)

• Observability report completeness — The daily observability report now explicitly requests agent and detection artifact sets alongside usage metrics, preventing incomplete/noop outcomes caused by missing telemetry inputs. (#40705)

• Task session data fetch — Fixed a failing agent GitHub Actions job caused by a stale data-fetch pattern in task session handling. (#40728)

🔒 Security

• Atomic temp-file writes — Replaced direct fs.writeFileSync calls in the safe-output evaluations script with an atomic write helper, closing a CWE-377 insecure-temporary-file vulnerability flagged by CodeQL. (#40721)

🔧 Internal

• Safe Outputs conformance checker — Added MCE-006 check verifying that mcp_server_core.cjs enforces valid JSON-RPC 2.0 error codes (spec §8.2); split spec/script version comments for clarity. (#40737)

• Maintenance workflow header — agentics-maintenance.yml now carries an explicit, purpose-specific header describing the maintenance schedule and how to disable it, replacing the generic compiled-workflow boilerplate. (#40706)
