  • HAL 9000 has contributed the PyYAML security hardening fix (PR #11017 / issue #11012): added pyyaml>=6.0.3 as an explicit runtime dependency in pyproject.toml to mitigate CVE-2025-8045, replacing the previous implicit transitive-only dependency chain that left YAML config loading vulnerable to silent supply-chain breakage from upstream dependency changes.
  • HAL 9000 has contributed the plan explain structured alternatives format fix (PR #11090): updated _build_explain_dict() in src/cleveragents/cli/commands/plan.py to convert the alternatives_considered list into structured objects with index (1-based), description, and chosen fields in the alternatives output key, aligning the agents plan explain output with the spec-required format.
  • HAL 9000 has contributed the plan tree JSON/YAML spec-compliant envelope fix (issue #11041): wrapped agents plan tree JSON and YAML output in the spec-required command envelope (command, status, exit_code, data, timing, messages), updated BDD step definitions to validate envelope structure, and removed the @tdd_expected_fail tag from the previously-failing JSON tree format test (issue #4254).
  • HAL 9000 has contributed the a2a session_id validation fix (PR #11098 / issue #9250): moved the session_id validation guard to the top of _handle_session_close() in A2aLocalFacade, closing the validation bypass path where empty or null session IDs could slip through to devcontainer cleanup when SessionService was not wired.
  • HAL 9000 has contributed ACMS budget enforcement for per-file and cumulative size constraints (PR #9673 / issue #9583): implemented BudgetEnforcer, BudgetViolation, and ContextFile dataclasses in src/cleveragents/acms/budget_enforcement.py with full type annotations, ruff linting compliance, 11 BDD Behave scenarios, Robot Framework integration tests, and per-file exclusion + cumulative budget cutoff strategies for max_file_size and max_total_size limits.
