Yeachan-Heo 85c5b0e01d Expand parity harness coverage before behavioral drift lands
The landed mock Anthropic harness now covers multi-tool turns, bash flows,
permission prompt approve/deny paths, and an external plugin tool path.
A machine-readable scenario manifest plus a diff/checklist runner keep the
new scenarios tied back to PARITY.md so future additions stay honest.

Constraint: Must build on the deterministic mock service and clean-environment CLI harness
Rejected: Add an MCP tool scenario now | current MCP tool surface is still stubbed, so plugin coverage is the real executable path
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep rust/mock_parity_scenarios.json, mock_parity_harness.rs, and PARITY.md refs in lockstep
Tested: cargo fmt --all
Tested: cargo clippy --workspace --all-targets -- -D warnings
Tested: cargo test --workspace
Tested: python3 rust/scripts/run_mock_parity_diff.py
Not-tested: Real MCP lifecycle handshakes; remote plugin marketplace install flows

# Mock LLM parity harness
This milestone adds a deterministic Anthropic-compatible mock service plus a reproducible CLI harness for the Rust `claw` binary.
## Artifacts
- `crates/mock-anthropic-service/` — mock `/v1/messages` service
- `crates/rusty-claude-cli/tests/mock_parity_harness.rs` — end-to-end clean-environment harness
- `scripts/run_mock_parity_harness.sh` — convenience wrapper
## Scenarios
The harness runs these scripted scenarios against a fresh workspace and isolated environment variables:
1. `streaming_text`
2. `read_file_roundtrip`
3. `grep_chunk_assembly`
4. `write_file_allowed`
5. `write_file_denied`
6. `multi_tool_turn_roundtrip`
7. `bash_stdout_roundtrip`
8. `bash_permission_prompt_approved`
9. `bash_permission_prompt_denied`
10. `plugin_tool_roundtrip`
## Run
```bash
cd rust/
./scripts/run_mock_parity_harness.sh
```
Behavioral checklist / parity diff:
```bash
cd rust/
python3 scripts/run_mock_parity_diff.py
```
Scenario-to-PARITY mappings live in `mock_parity_scenarios.json`.
## Manual mock server
```bash
cd rust/
cargo run -p mock-anthropic-service -- --bind 127.0.0.1:0
```
The server prints `MOCK_ANTHROPIC_BASE_URL=...`; point `ANTHROPIC_BASE_URL` at that URL and use any non-empty `ANTHROPIC_API_KEY`.
