|
|
|
|
**Change ID:** enterprise-undo
|
|
**Date:** 2026-04-24
|
|
**Status:** Shipped
|
|
|
|
## Summary
|
|
|
|
Implement the `@suaveplan/undo` package — a full enterprise-quality undo/redo engine for the genesis monorepo, replacing the old `enterprise-undo` reference implementation.
|
|
|
|
## What was built
|
|
|
|
- Synchronous `UndoStack<T>` with memory limits, transactions, EventBus
|
|
- `BranchingHistory<T>` with fork-on-diverge
|
|
- `AsyncUndoStack<T>` for async commands
|
|
- `HistoryCompressor<T>` / `compressHistory` for memory management
|
|
- `SelectiveUndoStack<T>` for non-linear undo by command ID
|
|
- `CommandMerger<T>` with time/count windows
|
|
- Structured errors via `UNDO_CODES` (6 codes)
|
|
- Zod schemas, OTel instrumentation, property-based tests (fast-check)
|
|
- 100% istanbul coverage, all co-located `.md` docs
