Tier 5 -- Setup/Infra Tests (~2,400 lines)

Hardest to test: interactive wizards, Docker, process spawning. Strategy: extract pure logic into testable functions, test the interactive parts by injecting mock input.

Channel setup helpers.

Tests to write:

src/sandbox/container.rs -- 22.1% -> 95% (+296 lines)

Docker container lifecycle. Test command construction without actual Docker.

Tests to write:

• test_container_config_to_docker_args -- generate correct docker run args

• test_container_network_config -- proxy network setup

src/sandbox/manager.rs -- 59% -> 95% (+114 lines)

Sandbox orchestration.

Tests to write:

• test_sandbox_policy_enforcement -- policy to container config mapping

src/sandbox/proxy/http.rs -- 37.5% -> 95% (+176 lines)

HTTP proxy for container network access.

Tests to write:

• test_proxy_allowlist_enforcement -- block disallowed domains

Execution Priority

Maximize coverage gain per unit of effort:

Order	Category	Lines Gained	Effort
1	Trace tests (Tier 2)	~7,000	Medium (high leverage, each test covers many modules)
2	Unit tests for 0% files (Tier 1 subset)	~3,500	Low (pure logic, no infrastructure)
3	Web handler tests (Tier 3)	~4,500	Medium (axum_test + in-memory DB)
4	Extension/MCP/WASM unit tests (Tier 1 remainder)	~3,500	Medium
5	CLI subcommand tests (Tier 4)	~2,100	Low-Medium
6	Setup wizard extraction + tests (Tier 5)	~2,400	High (requires refactoring)
7	LLM provider tests (Tier 1 subset)	~800	Medium
8	Remaining small files (Tier 6)	~2,000	Low

Notes

• All trace tests require --features libsql and use TestRigBuilder from tests/support/
• Web handler tests can use axum::test helpers or build the router directly
• CLI tests should call handler functions directly, not shell out to the binary
• Setup wizard tests require extracting pure logic from interactive prompts first
• Sandbox/container tests should verify command construction, not run Docker
• Worker tests can use TraceLlm for the LLM provider, same as trace tests
