# TASK-083-01-02: Tests and Docs FastMCP 3.x Dependency and Runtime Audit

**Parent:** [TASK-083-01](./TASK-083-01_FastMCP_3x_Dependency_and_Runtime_Audit.md)  
**Status:** ✅ Done  
**Priority:** 🔴 High  
**Depends On:** [TASK-083-01-01](./TASK-083-01-01_Core_FastMCP_Dependency_Runtime_Audit.md)

---

## Objective

Add tests and documentation updates for **FastMCP 3.x Dependency and Runtime Audit**.

---

## Repository Touchpoints

- `tests/unit/adapters/mcp/test_runtime_inventory.py`
- `tests/unit/adapters/mcp/test_provider_inventory.py`
- `README.md`
- `_docs/_MCP_SERVER/README.md`
- `_docs/_MCP_SERVER/fastmcp_3x_migration_matrix.md`

---

## Planned Work

### Regression Scenarios (Required)

1. dependency baseline path: FastMCP dependency and runtime notes are aligned to the selected 3.x baseline.
2. runtime inventory path: all MCP area families in the runtime are represented in one canonical inventory and validated by tests.
3. bootstrap seam path: startup no longer depends on hidden side-effect imports as the default composition mechanism.
4. gap visibility path: known inventory mismatches (for example metadata coverage gaps) are explicitly surfaced in docs and tests.

### Metrics To Capture

- runtime inventory coverage ratio (area modules vs inventory entries)
- side-effect bootstrap dependency count (target trending to 0 for default startup)
- unresolved 2.x coupling points after audit (explicit list, target monotonically decreasing)

### Documentation Deliverables

- update task-linked docs with a before/after summary tied to the captured metrics
- document exact test commands, fixtures, and profile/config used during validation
- record compatibility or migration notes when behavior differs between surfaces

---

## Acceptance Criteria

- all required regression scenarios are implemented and passing in CI/local test runs
- metrics are captured with baseline vs post-change values and attached to the task update
- docs include the regression matrix and explain expected behavior boundaries
- no untracked regressions are observed on related MCP bootstrap/inventory/platform paths

---

## Atomic Work Items

1. Implement the required regression scenarios in focused unit/integration tests.
2. Run the target suites, collect metric outputs, and compare to baseline values.
3. Update docs with regression matrix, metric table, and migration/compatibility notes.
4. Verify adjacent surfaces for spillover regressions and document the result.
