weiihann	1051e7be0c	nomt/merkle, nomt/db: adapt to EIP-7864 stem-based types (Phase D) ... Remove leaf compaction from PageWalker.compactStep, replace KeyValue with StemKeyValue throughout the merkle engine and worker, and update DB.Update to accept pre-hashed stem key-value pairs. Key change: singleThreadedUpdate now uses the same depth-7 child-index partitioning as the parallel path, ensuring identical intermediate hashes without leaf compaction.

weiihann	cb3e13d93d	nomt/merkle: add Phase 7 parallel workers for trie updates ... Parallelize the PageWalker trie update across multiple goroutines by partitioning sorted operations by the root page's 64 child subtrees (first 6 bits of each key path). Each worker runs an independent PageWalker constrained to child pages below the root (using parentPage mechanism), producing ChildPageRoots. After all workers complete, a root walker places the child roots using AdvanceAndPlaceNode and concludes with the final trie root. Workers operate on disjoint page subtrees so no synchronization is needed during computation — only sync.WaitGroup for goroutine join.

weiihann	cf10f3d997	nomt/db: add Phase 5 unified NOMT trie database ... Implement the orchestration layer combining Bitbox storage with the PageWalker merkle engine: - DB.Open: creates/opens Bitbox HT file, runs WAL recovery - DB.Update: sorts ops, runs PageWalker, persists via Bitbox sync - DB.LoadPage: reads pages from Bitbox for NodeReader compatibility - BitboxPageSet: PageSet implementation backed by on-disk Bitbox storage The DB handles only trie structure (merkle pages). Flat key-value storage stays on geth's PebbleDB via existing infrastructure. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-12 17:18:31 +08:00
