+## D3 — Whitespace & Errors: PASS @2026-06-15T04:40:18Z
+
+**First verdict (FAIL @2026-06-15T04:34:35Z):** bare `.` raised `ValueError` not `LexError` (AF-1).
+
+**Re-verified after fix commit f40a364:**

+```
+Ran 21 tests in 0.000s — OK                                ✓
+['NUMBER', 'PLUS', 'NUMBER', 'EOF']  (whitespace skipped)  ✓
+tokenize('.')  → LexError: invalid number literal '.' at position 0  ✓
+tokenize('1 @ 2')  → LexError: unexpected character '@' at position 2  ✓
+```
+
+Valid floats unaffected by fix: `.5` → `0.5`, `10.` → `10.0`, `3.5*(1-2)` correct.

+Ran 21 tests in 0.000s
+OK

+
+21 tests (was 20; `test_bare_dot_raises_lex_error` added). All three required DoD examples covered and passing.

+
+## Adversary findings
+
+### AF-1 (CLOSED @2026-06-15T04:40:18Z): Bare `.` leaked `ValueError` instead of `LexError`
+
+**Fix:** `lexer.py` now wraps `float(raw)` / `int(raw)` in try/except, re-raises as `LexError`. Test added.  
+Re-tested: `tokenize('.')` now raises `LexError: invalid number literal '.' at position 0`. ✓
