+## 2026-10-27: bag counted things its list didn't show (Claude Code)

+- Owner's exported save: bag total 1,522 but the list showed nothing for 1,000 basalt (from the
+  dev console's give), 200 clay (source not traced) and 322 molten slag (vacuumed with the Flask;
+  not in BAG_ORDER). `bagAdd` now stores solids as their drill yield; `deserializeWorld` converts
+  solids already in a saved bag; `bagMaterials` appends anything outside BAG_ORDER; dev `give`
+  reports what it added and refuses gases and solids with no yield.
+- Files: `src/sim/items.js`, `src/sim/save.js`, `src/ui/hud.js`, `src/sim/devconsole.js`,
+  `test/t_basics.js`, `test/t_dev_console.js`. Tests: `python3 test/run_all.py --browser` all passed.
