+## 2026-10-27: OS pointer hidden over the game (Claude Code)
+
+- The canvas used `cursor: crosshair`, so the system pointer showed on top of the game's own aim;
+  it was hidden only while a gamepad was in use. Now `cursor: none` on the canvas always; the
+  gamepad's `nocursor` toggling is gone. Files: `src/styles/style.css`, `src/ui/input.js`,
+  `src/ui/gamepad.js`.
+
+## 2026-10-27: t77 identify ores with the cursor (Claude Code + Codex)
+
+- New `src/ui/cursor.js`: `oreLike`, `bitNeeded`, `pingVisible` (a ping's cells, while showing),
+  `hoveredVein` (cached capped flood fill and edges), `cursorLabelAlpha` (2 s then fade).
+  `hoverInfo` identifies pinged cells under fog and says "needs <bit>"; `drawCursorLabel` honours
+  the new Off / Ores only / Everything setting (`SET.cursorLabel`, booleans migrated);
+  `drawHoveredVein` in `src/render/overlays.js` draws the outline.
+- Tests: `test/t_cursor.js`, `test/t_smooth.py`, `test/play.py`; `python3 test/run_all.py --browser`
+  all passed. Open: the outline keeps its old shape if the vein is drilled while hovered, until
+  the cursor moves to another cell.

 ## 2026-10-27: t75 ping recharge, natural ore colour, glints (Claude Code)
 
 - 10 s recharge (`PING_RECHARGE`, `pingWait`) with a drill panel chip. `pingImage` draws veins in
