+# JOURNAL-lex — Adversary
+
+## 2026-06-15 — Wake 1
+- Read phase plan: mission is lexer for Python arithmetic calculator
+- Checked origin/main: only seed commit, Builder has not pushed any work yet
+- Set up REVIEW-lex.md, BACKLOG-lex.md, STATUS-lex.md, JOURNAL-lex.md
+- Will poll for Builder claims
+
+## 2026-06-15 — Wake 2 (watchdog ping)
+- Pulled claim(D1,D2,D3,D4) commit from Builder — all gates claimed at once
+- Read STATUS-lex.md for verification commands (did NOT read JOURNAL before verdicts)
+- Cold-verified all four gates from my own clone:
+
+### D1 verification
+- `tokenize('42')` → NUMBER(42 int) EOF ✓
+- `tokenize('3.14')` → NUMBER(3.14 float) EOF ✓
+- `tokenize('.5')` → NUMBER(0.5) EOF ✓
+- `tokenize('10.')` → NUMBER(10.0) EOF ✓
+
+### D2 verification
+- `tokenize('1+2*3')` kinds → ['NUMBER','PLUS','NUMBER','STAR','NUMBER','EOF'] ✓
+- `tokenize('3.5*(1-2)')` → correct full token list ✓
+- All 6 operator kinds present in test suite ✓
+
+### D3 verification
+- `tokenize('  12  +  3 ')` → ['NUMBER','PLUS','NUMBER','EOF'] ✓
+- `tokenize('1 @ 2')` → LexError: "unexpected character '@' at position 2" ✓
+- '@' and '2' both in error message ✓
+
+### D4 verification
+- `python -m unittest -q` → Ran 24 tests, OK, exit 0 ✓
+- Three mandatory test inputs from DoD confirmed in test suite ✓
+
+### Break-it probes
+- `tokenize('1.2.3')` → ValueError (not LexError) — logged as AF-01 (non-blocking)
+- `tokenize('.')` → ValueError (not LexError) — same issue
+- `tokenize('..')` → ValueError (not LexError) — same issue
+- `tokenize('1x')` → LexError at position 1 ✓ (x is invalid char)
+- `tokenize('\n')` → LexError ✓ (newline not in whitespace set)
+- `tokenize('')` → [Token(EOF, None)] ✓
+- SLASH operator explicitly tested ✓
+
+### Verdict
+All four gates: PASS. One informational finding (AF-01: ValueError for malformed number
+literals). No VETO issued. Builder may write ## DONE.
+
+## 2026-06-15 — Builder Wake 2 (post-verdicts)
+
+Pulled Adversary verdict commit. All four gates PASS.
+
+Addressed AF-01: wrapped `float(raw)` in try/except ValueError → re-raises as LexError.
+
+```
+$ python -m unittest -q
+Ran 24 tests in 0.000s
+OK
+
+$ python -c "
+from calc.lexer import tokenize, LexError
+for case in ['1.2.3', '.', '..']:
+    try:
+        tokenize(case)
+        print(f'FAIL: {case!r}')
+    except LexError as e:
+        print(f'OK: {case!r} -> LexError: {e}')
+"
+OK: '1.2.3' -> LexError: malformed number '1.2.3' at position 0
+OK: '.' -> LexError: malformed number '.' at position 0
+OK: '..' -> LexError: malformed number '..' at position 0
+```
+
+Updated STATUS-lex.md to ## DONE. Phase lex complete.
