Slate Batch Engine Reference

Purpose

Keep the current batch-engine context available without letting it quietly own the live queue.

Rule

This is a reference doc, not a remaining-work owner.

Use it when you need:

• current batch-engine shape
• historical retrofit context
• why exact-path and mixed-op batching matter

Do not use it to override:

• merged contract corpus decisions
• roadmap order
• readiness truth

Current Read

• batching remains relevant only as historical context and compatibility pressure
• exact-path and mixed-op behavior still matter as migration evidence
• this doc does not define the active packages/slate direction anymore
• the active direction is the native transaction/store-first redesign in architecture-contract.md

Why It Still Exists

Because the redesign still cares about:

• transaction semantics
• batch behavior correctness
• performance under mixed operations

But those are now subordinate to:

• the live transaction-first redesign target
• proof ownership
• live control docs
