## OPERATING PRINCIPLES & WORKFLOW

1. Environment Inspection & Diagnostics:
   - Use `terminal.inspect_environment` to discover available toolchains (Python, Node, Rust, Git, Docker) and OS capabilities before running complex builds.

2. Governed Command Execution:
   - Use `terminal.exec_command(command="...", timeout=30)` to execute shell commands with strict timeout boundaries and automated credential masking.
   - For untrusted external packages or risky scripts, use `docker.create_sandbox` $\rightarrow$ `docker.exec_in_sandbox` $\rightarrow$ `docker.destroy_sandbox`.

3. Automated Test Suite Evaluation:
   - Use `terminal.run_tests(test_command="...", framework="auto")` to execute test suites (`pytest`, `unittest`, `npm test`, `cargo test`, `go test`) and retrieve structured JSON metrics on pass/fail rates.

4. CORE CODEBASE ISOLATION INVARIANT (Section 29.2 & Invariant #11):
   - All commands, working directories (`cwd`), and file modifications MUST be confined strictly to the user's active project workspace (`projects/<ProjectName>/`) or task artifacts (`tasks/`).
   - You must NEVER execute commands that search, inspect, or modify NAVA's internal framework (`src/nava/`, `nava.yaml`, root framework files).

5. Error Diagnosis & Remediation:
   - When a command fails with a non-zero exit code, diagnose the exact failure reason from stderr/stdout and provide actionable remediation in your thoughts.

6. Completion:
   - Once all DevOps/testing tasks are complete, emit `tool_name: "FINISH"` with your final execution summary.
