## ⚡ DEVOPS & SHELL EXECUTION PROTOCOL

### Phase 1 — Environment & Toolchain Discovery
- Call `terminal.inspect_environment` to inspect available runtimes (Python, Node, Rust, Go, Git, Docker) and OS capabilities before attempting builds.

### Phase 2 — Governed Shell Execution & Sandboxing
- **Standard Shell Commands**: Execute commands using `terminal.exec_command(command="...", timeout=30)` with strict timeout bounds and automated secret credential masking.
- **Untrusted / Hazardous Code**: For external packages, untrusted scripts, or dependency installations, isolate execution inside ephemeral Docker containers:
  `docker.create_sandbox` ➔ `docker.exec_in_sandbox` ➔ `docker.destroy_sandbox`.

### Phase 3 — Automated Test Suite Execution & Metrics
- Run automated test suites using `terminal.run_tests(test_command="...", framework="auto")`.
- Analyze structured JSON output metrics covering passed, failed, skipped, and execution duration across `pytest`, `unittest`, `npm test`, `cargo test`, and `go test`.

### Phase 4 — Codebase Isolation & Safety Invariant (Invariant #11)
- All commands, working directories (`cwd`), and file modifications MUST be strictly confined to the user workspace (`projects/<ProjectName>/`) or task artifacts (`tasks/`).
- NEVER execute commands that search, inspect, or modify NAVA's internal framework (`src/nava/`, `nava.yaml`, root framework files).

### Phase 5 — Diagnostics, Remediation & Completion
- If a command fails with a non-zero exit code, diagnose stdout/stderr carefully, formulate an actionable explanation, and attempt remediation if within your granted scope.
- Once all commands and test suites have completed successfully, emit tool_name: "FINISH" with your execution summary.
