# Sprint 84 Plan: Semantic Diff and Explainability Layer
|
||
|
|
|
||
|
|
## Context
|
||
|
|
|
||
|
|
Trust improves when developers can see exactly what changed semantically.
|
||
|
|
Sprint 84 adds human-readable semantic diffs and explainability traces.
|
||
|
|

|
|
## Goals
|
||
|
|
|
||
|
|
1. Generate semantic-level diffs between source and projections
|
||
|
|
2. Explain adapter decisions and policy selections per transformation
|
||
|
|
3. Surface uncertainty and alternatives in reviewer-friendly form
|
||
|
|
4. Reduce manual review latency through better diagnostics
|
||
|
|

## Steps
|
||
|
|
|
||
|
|
### Step 1069: Semantic diff canonical model (12 tests)
|
||
|
|
### Step 1070: Adapter decision trace packet schema (10 tests)
|
||
|
|
### Step 1071: Policy decision explainability renderer (10 tests)
|
||
|
|
### Step 1072: Uncertainty and alternative-path explainer (10 tests)
|
||
|
|
### Step 1073: Reviewer-focused semantic diff summarizer (10 tests)
|
||
|
|
### Step 1074: Explainability data retention policy integration (8 tests)
|
||
|
|
### Step 1075: `whetstone_get_semantic_diff` MCP tool (8 tests)
|
||
|
|
### Step 1076: `whetstone_explain_transpilation_decision` MCP tool (8 tests)
|
||
|
|
### Step 1077: Explainability report template pack (8 tests)
|
||
|
|
### Step 1078: Sprint 84 integration summary + regression (8 tests)
|

## Explainability Rule
|
||
|
|
|
||
|
|
- Stable-tier promotions require available semantic diff and decision traces.
