From af4810e2ec8e454e4bb616c685e907eaee04c874 Mon Sep 17 00:00:00 2001 From: Adam Soltys Date: Thu, 10 Sep 2026 07:18:09 -0700 Subject: Ark state moves to IndexedDB: raw bytes on disk, memory-fronted, write-behind. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit localStorage held a deep wallet's ark state as ~700KB of JSON (UTF-16 on disk), parsed on every boot and stringified on every save, and the wallet cache blob carried a second ~600KB copy. src/ark/store.js keeps the state in IndexedDB (db coinos-ark) with each coin's signed bytes as a Uint8Array, fronted by an in-memory map so loadArkState/saveArkState stay synchronous: reads return clones, writes coalesce (200ms) and flush immediately when the page hides. Existing localStorage copies migrate on first open (newest _rev wins) and are removed only after the IndexedDB write completed; no IndexedDB means localStorage exactly as before. Records keep their btc-wallet-cache::ark… keys, and a wallet wipe clears both stores via the new per-feature wipeCache hook. The ark cache extension is now syncOnly: it still rides the sync snapshot (and the Blossom blob) but the local wallet cache no longer embeds it — measured on a live wallet the cache blob went from 655KB to 10KB. Verified in the live tab: all wallets migrated, bytes raw on disk, balance and coin set unchanged, localStorage ark keys gone. tools/ark-store-test.js covers migration by _rev, clone-on-read, write-behind, wipe and fallback.
