Adds specs/t27mcp/integration_test.t27 which ties the already-landed Wave B/C/D/E handler specs together via cross-spec invariants: - T27L event kind ladder 10..13 is strictly monotone - Tier 1 tool indices (0, 1, 16) are within server dispatch range - Chain link LK_REQUEST_TO_DECOMPOSITION (index 8) is reachable - Automation status LP_COUNT == 3 matches layer_count - RSI evidence levels are strictly ordered 8 tests pass, 6 invariants proved, FAIL 0.

t27mcp: Wave 2 -- integration test verifying Tier 1 cross-spec contracts
Adds specs/t27mcp/integration_test.t27 which ties the already-landed
Wave B/C/D/E handler specs together via cross-spec invariants:
8 tests pass, 6 invariants proved, FAIL 0.
Closes #13566

Note
Low Risk
Spec-only addition with no runtime or handler behavior changes; risk is limited to maintenance if duplicated constants drift from the source specs.
Overview
Adds
specs/t27mcp/integration_test.t27(McpIntegrationTest), a Wave 2 T27 spec that locks in Tier 1 MCP runtime integration without new handlers—only assertions against values that must stay aligned across existing specs.The module defines mirrored constants (T27L event kinds 10–13, tool indices 0/1/16, chain link 8, layer count 3, five metric fields, RSI evidence levels) plus small helpers (
tek_ladder_monotone,tier1_tools_dispatchable, etc.). Eight tests exercise ordering, dispatch range, automation layer count, chain coverage, metrics, RSI thresholds, and stable PASS/BLOCKED/FAIL codes. Six invariants keep those contracts enforced continuously.Reviewed by Cursor Bugbot for commit 1716f80. Bugbot is set up for automated code reviews on this repo. Configure here.
