+# #2776 Fix item-nr for enumerate variants created via new-list
+
+### How to test
+1. Clear cache
+   - macOS: delete `~/Library/Caches/MoganLab`
+   - Linux: delete `~/.cache/MoganLab`
+   - Windows: delete `%appdata%/AppData/Roaming/MoganLab` and `%appdata%/AppData/Local/MoganLab`
+2. Restart Mogan, open a new document
+3. Insert → Ordered list → "1, 2, 3, ..." (`enumerate-numeric`)
+4. Add 3 items (type text, press Enter for each)
+5. Inside item 3, delete the item marker (Backspace), then insert a nested ordered list via shortcut `1. Tab` (`enumerate`)
+6. Verify the nested list starts from 1 (not continuing from 4)
+
+## 2026/03/03
+### What
+The `list` macro condition used `enumerate-level` to decide whether to preserve or reset `item-nr`. This only worked for the `enumerate` macro (shortcut `1. Tab`) which increments `enumerate-level`. Variants created via `new-list` (e.g. `enumerate-numeric`, `enumerate-alpha`) do not go through `enumerate` and leave `enumerate-level` at 0, causing incorrect `item-nr` behavior.
+
+### Why
+The previous fix (202_65) checked `enumerate-level == 1` to identify top-level lists. But `new-list`-based variants never set `enumerate-level`, so the condition always fails for them — `item-nr` resets to 0 even at the top level, and nested lists inherit the parent's `item-nr` instead of resetting.
+
+Fixes: https://github.com/XmacsLabs/mogan/issues/2108
+
+### How
+In `TeXmacs/packages/standard/std-list.ts`:
+
+- Added a new variable `list-depth` (initialized to 0)
+- All three list macros (`list`, `list*`, `list-continued`) now increment `list-depth` via `<with>`
+- Changed the `item-nr` condition from `enumerate-level == 1` to `list-depth == 0`
+
+Since `list-depth` is incremented by all list macros (not just `enumerate`), the condition works uniformly for every list type.
