# Sprint 142 Plan: Text-to-AST Incremental Synchronization for C++
|
||
|
|
|
||
|
|
## Context
|
||
|
|
|
||
|
|
Hybrid mode needs fast text editing without losing AST consistency. Sprint 142
|
||
|
|
adds deterministic incremental text->AST synchronization with C++ priority.
|
||
|
|

|
|
## Goals
|
||
|
|
|
||
|
|
1. Convert C++ text edits into incremental AST updates
|
||
|
|
2. Preserve node identity/stability where possible
|
||
|
|
3. Emit structured sync diagnostics when mapping is ambiguous
|
||
|
|
4. Keep sync deterministic for identical edit streams

## Steps
|
||
|
|
|
||
|
|
### Step 1659: Incremental text edit packet schema (10 tests)
|
||
|
|
### Step 1660: C++ text-delta parser bridge model (10 tests)
|
||
|
|
### Step 1661: Node identity preservation policy model (10 tests)
|
||
|
|
### Step 1662: Incremental sync diagnostics model (10 tests)
|
||
|
|
### Step 1663: `whetstone_sync_text_to_ast` MCP tool (8 tests)
|
||
|
|
### Step 1664: `whetstone_get_sync_diagnostics` MCP tool (8 tests)
|
||
|
|
### Step 1665: `whetstone_get_sync_identity_report` MCP tool (8 tests)
|
||
|
|
### Step 1666: Sync confidence score model (8 tests)
|
||
|
|
### Step 1667: Incremental sync report artifact (8 tests)
|
||
|
|
### Step 1668: Sprint 142 integration summary + regression (8 tests)

## Architecture Gate
|
||
|
|
|
||
|
|
- Incremental sync must be deterministic for identical text deltas
|
||
|
|
- Identity preservation rules must be explicit and auditable
|
||
|
|
- Ambiguous mappings must produce structured diagnostics
