indexer_rust	in-progress		The [index] engine ( parse-for-index → extract → SQLite persist → incremental sync ) should be written in Rust. Crate: `reqlan-index` over `reqlan-parse` per ["../core_analysis/rust_port.rq".rust_crate_layout]. Extractor ports ["../../crates/reqlan-index/src/extract.rs"] including [wildcard_reference_edges]. Store ports schema v4 ( ["../../packages/analytical/src/index-store/schema.ts"] ) via rusqlite; diagnostics live in `index-diagnostics.sqlite` on the same engine. Sync keeps [nonblocking_index]: per-file upsert, mtime skip, hard rebuild, cancellable progress. Not the Langium LSP. Comment-file indexing: [index_code_files].	0.172
nonblocking_index	done		Index sync must stay non-blocking for the host UI ( notably [activity_bar_doc.activity_bar] and [workspace_pane_doc.workspace_loading] ). Editor startup is gated by ["../extension/host/activation.rq".first_paint_startup]; discovering a base must not construct Langium services, which are initialized lazily on the first parse. While syncing, surface progress — state, processed / total, and the current file — in [workspace_pane_doc.workspace_pane] and [ideas_summary_doc.index_panel]. In-flight sync must be cancellable from those surfaces; cancel keeps already-indexed rows and returns the index to ready. Incremental behaviour ( see also [indexing_incrementality] ): - Single-file create / change / delete via watchers indexes only that file — never a full base walk. - Soft full sync ( `syncWorkspace` / Refresh ) skips parse + persist when the file's mtime matches the value stored on the documents row. - Hard refresh ( `clearAndRebuildIndex` / Clear & rebuild ) wipes the store and reindexes every file. - Every sync and stale check applies `.rqignore` to the paths it receives, the same as the base walk; the native single-file index also drops an ignored path. Thus base discovery cannot make the first sync index ignored files. Implemented by [workspace_index]; editor adapter [editor_index_adapter].	0.372
