# Sprint 131-140 Index

## Scope

This block closes MCP wiring/runtime/tool-surface gaps and formalizes release
readiness gates for tool availability, contract stability, and compatibility.

## Sprint Map

- Sprint 131 (`1549-1558`): MCP Tool Surface Source-of-Truth and Manifest Sync
- Sprint 132 (`1559-1568`): MCP Runtime Fingerprinting and Binary Freshness Guarantees
- Sprint 133 (`1569-1578`): MCP Tool Contract Conformance and Schema Drift Prevention
- Sprint 134 (`1579-1588`): End-to-End MCP Reachability and Routing Integrity
- Sprint 135 (`1589-1598`): Deterministic MCP Execution Telemetry and Replay Packs
- Sprint 136 (`1599-1608`): Capability and Permission Gate Unification for MCP Tools
- Sprint 137 (`1609-1618`): Multi-Binary MCP Runtime Selection and Health Checks
- Sprint 138 (`1619-1628`): Distributed Orchestrator-to-MCP Handoff Consistency
- Sprint 139 (`1629-1638`): MCP Backward Compatibility and Deprecation Governance
- Sprint 140 (`1639-1648`): Program-Wide MCP Wiring Closure and Release Gate

## Expected Outcomes

- Deterministic source/runtime tool-surface parity
- Deterministic runtime freshness and fingerprint checks
- Deterministic tool contract and routing conformance gates
- Deterministic compatibility/deprecation governance
- Single closure gate for MCP release certification
