# TASK-092-05-01: Core Sampling Assistant Tests and Documentation

**Parent:** [TASK-092-05](./TASK-092-05_Sampling_Assistant_Tests_and_Documentation.md)  
**Status:** ✅ Done  
**Priority:** 🟡 Medium  
**Depends On:** [TASK-092-04](./TASK-092-04_Router_Integration_Masking_and_Budget_Control.md)

---

## Objective

Implement the core code changes for **Sampling Assistant Tests and Documentation**.

---

## Repository Touchpoints

- `tests/unit/adapters/mcp/test_assistant_runner.py`
- `tests/unit/router/application/`
- `_docs/_MCP_SERVER/README.md`
- `_docs/_ROUTER/RESPONSIBILITY_BOUNDARIES.md`
---

## Planned Work

### Slice Outputs

- enforce bounded sampling usage with explicit masking and budget controls
- keep assistant outputs typed and policy-gated
- prevent assistant paths from bypassing router safety or inspection truth layers

### Implementation Checklist

- touch `tests/unit/adapters/mcp/test_assistant_runner.py` with explicit change notes and boundary rationale
- touch `tests/unit/router/application/` with explicit change notes and boundary rationale
- touch `_docs/_MCP_SERVER/README.md` with explicit change notes and boundary rationale
- touch `_docs/_ROUTER/RESPONSIBILITY_BOUNDARIES.md` with explicit change notes and boundary rationale
- add or update focused regression coverage for the slice behavior
- capture before/after evidence tied to the slice outputs

### Review Notes To Attach

- rationale per changed touchpoint and any explicit no-change decisions
- exact test commands and profile/config context used during validation
- deferred work list with safety rationale

---

## Acceptance Criteria

- assistant behavior is request-bound, typed, and policy-compliant
- masking and budget limits are deterministic and test-covered
- fallback behavior is explicit when sampling is unavailable or blocked
- no boundary violations relative to semantic/safety/truth split

---

## Atomic Work Items

1. Implement bounded assistant behavior and policy hooks in listed touchpoints.
2. Add tests for available, unavailable, masked, and budget-exceeded paths.
3. Capture typed output examples for each terminal assistant status.
4. Document allowed/forbidden assistant responsibilities for this slice.
