Local iPhone-chrome demo indexes realm JSON files into boxel_index via node:sqlite, queues chat with card attachments, and reconciles with the same classify/push/pull rules as boxel realm sync. Native messenger target is matrix-sdk-rust, not matrix-js-sdk. Co-authored-by: Chris Tse <christse@users.noreply.github.com>
Lite indexer stamps _title, fullName, initials, handle, and kindLabel into boxel_index.search_doc at index time. Search is json_extract on that column; a contrast filesystem scan is shown only to prove those computed strings are absent from the JSON:API source.

Background and Goal
This adds a local, runnable prototype of an offline Boxel messenger that indexes realm card JSON files into SQLite and later reconciles with the same classify/push/pull rules as
boxel realm sync. It is the data plane a NativeScript 9.1 iOS / Mac Catalyst app would share; it is not a replacement for the Ember host or for prerendered card execution.The native Matrix client on that path is matrix-sdk-rust (UniFFI, SQLite store, same stack as Element X).
matrix-js-sdkstays in the host. The prototype’srooms/messagestables stand in formatrix.sqliteuntil that FFI is wired.Search is SQLite
boxel_index.search_doc, not the JSON files. Computed keys (_title,fullName,initials,handle) are stamped at index time and queried withjson_extract. A query such asMGor@maple.grovehits the index and misses a filesystem scan of the JSON:API source.Where to start
docs/nativescript-offline-messenger.md— feasibility, NativeScript 9.1 fit, rust-vs-JS Matrix choice, two-SQLite-file layout.prototypes/boxel-native/core/— filesystem, lite indexer (boxel_index), computedsearch_doc, sync-logic port, messenger stand-in.prototypes/boxel-native/web-simulator/— iPhone chrome UI. Run withnode web-simulator/server.mjsand open http://127.0.0.1:4173/Key decisions and non-obvious mechanics
pristine_docplus asearch_docthat includes computed fields the JSON file does not store. Search never greps realm files.packages/boxel-cli/src/lib/sync-logic.ts(dependency-free copy in the prototype).boxel-index.sqliteandmatrix.sqliteseparate. Card bytes move through realm file sync; chat attachments are Matrix events pointing at a realm URL.node:sqliteis the local stand-in;ns debug ioson a Mac with Xcode is the NativeScript 9.1 path.
