+- **Dev console name discovery and keys (t94, 2026-10-28).** The owner chose close-name
+  suggestions and a filtered material list because they had not known material names could
+  contain spaces. Match names with spaces ignored; keep display and internal names, with no
+  hover hint. Add Tab completion, persistent 50-command history, command-specific help,
+  output clearing and red errors for easier use.
 - **The dev console ships in every build (t66, 2026-10-27).** The owner is happy for players to
   experiment and play their own way, so the console isn't hidden behind a dev build. Turning it

+- Added case/space-insensitive material lookup, three close giveable suggestions and
+  materials filtering with internal names. Command definitions hold help usage/examples
+  and keyword candidates. Pure helpers handle cycling completion and capped 50-command
+  history; UI owns storage (all accesses guarded), keys, output clearing and red errors.
+  Tab, arrows and Ctrl+L stop before game controls. Simulation tick behaviour unchanged.
+- Tests added first: name/filter/help checks failed before implementation. Corrected test
+  assumptions for the separate giveable Copper ore vein and for the latest submitted
+  history command. Full python3 test/run_all.py --browser: ALL PASSED (34 headless,
+  9 browser suites); console checks: 77 Node, 27 browser. Log: /tmp/t94-all-browser.log.
+  Browser checks cycling Tab, Up/Down, Ctrl+L, exact bot/control isolation, colours,
+  clear and history across page reload. Saved and inspected shots/t94-console.png.
