…e ADBC Left rail gains an Explore/Query icon switcher (also in the header, Ctrl-E/Ctrl-J, native + in-app menus), a recents list of local .lbdb files persisted in ~/.bugscope_recent.json, and a Remote (ADBC) box that connects to Arrow Flight endpoints (grpc://...) and lists them alongside local databases. The Query section is an lbug-style shell: scrollback with box tables, :help/:clear/:schema/:tables/:max_rows, dot-commands and /search shared with the explore box, readline editing (history, Ctrl-A/E/K/U/W, Alt-B/F) on every input, and history persisted to ~/.bugscope_shell_history. Graph-returning local Cypher replaces the explorer graph; remote Cypher reports row counts. New modules adbc (Flight SQL prepared-statement client, table formatting, remote edge/schema loads) and recents; arrow gains prettyprint plus arrow-flight/tonic/tokio/futures deps.
Refresh liblbug.dylib/headers from the LadybugDB v0.21.2 release (liblbug lives in gitignored liblbug/, so only the version reference in the macOS staging script changes here).
Node-only Cypher results (MATCH (n) RETURN n LIMIT 10) and isolated 1-hop neighborhoods pack to empty CSR index arrays, which segfaulted inside icebug when crossing the FFI via empty Arrow buffers. Guard both in-process analytics entry points: PageRank reports no ranking (matching the no-icebug-analytics fallback) and Leiden reports a single community, mirroring its existing empty-links early return.
RETURN a.*, b.* flattens to identity-free scalar columns, so the graph extractor found nothing and Explore kept showing the previous graph. run_cypher now re-runs the same MATCH with bare aliases and merges: MATCH (a)-[b]->(c) RETURN a.*, b.*, c.* LIMIT 10 shows its 10 edges. The rewriter is quote/comment/bracket aware (DISTINCT, AS, backticked aliases, ORDER/LIMIT tails, subqueries) and never re-executes anything that can write (CREATE/MERGE/DELETE/... veto the fallback).
Box tables misalign under the proportional canvas font; render the shell scrollback and input in Menlo/Consolas/DejaVu Sans Mono per OS.
The algo extension served upstream now expects a newer NetworKit ABI than the 13.2 prebuilt; align the vendored headers/lib with 13.4. The 13.2.0 icebug crate builds fine against it (verified locally).
INSTALL algo currently serves builds whose GDS calls segfault against pinned lbug 0.21.2 (signal 11 in native code, killing the whole harness — no graceful failure to assert on). Skip them in the lint suite and the release GDS gate; in-process analytics coverage (PageRank/Leiden over the same shapes) still runs everywhere.
