+# Sprint 135 Plan: Deterministic MCP Execution Telemetry and Replay Packs
+
+## Context
+
+To debug wiring regressions, execution traces must be deterministic and compact.
+Sprint 135 standardizes MCP execution telemetry with replay-ready packets.
+
+---
+
+## Goals
+
+1. Capture deterministic MCP execution telemetry per tool call
+2. Normalize argument/result traces for replay and comparison
+3. Build compact replay packs for cross-run debugging
+4. Support low-context agent diagnosis of MCP regressions
+
+---
+
+## Steps
+
+### Step 1589: MCP execution event schema (10 tests)
+### Step 1590: Argument/result canonicalizer model (10 tests)
+### Step 1591: Deterministic replay pack composer (10 tests)
+### Step 1592: Replay divergence comparator model (10 tests)
+### Step 1593: `whetstone_capture_mcp_execution_trace` MCP tool (8 tests)
+### Step 1594: `whetstone_export_mcp_replay_pack` MCP tool (8 tests)
+### Step 1595: `whetstone_compare_mcp_replays` MCP tool (8 tests)
+### Step 1596: Trace quality scorer model (8 tests)
+### Step 1597: MCP replay diagnostics artifact (8 tests)
+### Step 1598: Sprint 135 integration summary + regression (8 tests)

+
+## Architecture Gate
+
+- Trace normalization must produce stable outputs
+- Replay comparisons must return structured divergence packets
+- Trace capture must preserve privacy and workspace scoping rules
+- Max 600 lines per header
