+## Design notes
+
+**evaluator.py**: Straightforward AST walker. `_normalize(v)` converts a float to int when `v == int(v)` — this handles the D3 requirement cleanly for both direct integer arithmetic and whole-valued division results. Division by zero is caught before the `/` operation and wrapped as `EvalError`.
+
+**calc.py**: Catches `LexError`, `ParseError`, and `EvalError`; prints `error: <message>` to stderr and exits 1. No traceback leaks.
+
+**test_evaluator.py**: 13 tests covering all D1 arithmetic cases, D2 true division and EvalError, D3 type assertions. Full 42-test suite (lex 16 + parse 13 + eval 13) passes.

+# JOURNAL — phase lex
+
+## Approach
+
+- `Token` is a `dataclass` with `kind: str` and `value: Union[int, float, str, None]`.
+- `tokenize()` is a simple single-pass scanner using index `i`.
+- Numbers: greedy scan of digits and `.`; if `.` present → `float`, else → `int`.
+- Operators/parens: single-char dispatch via `_SINGLE` dict.
+- Whitespace (space, tab): skipped silently.
+- Anything else: raises `LexError` with the offending char and position.

+## Design decisions

+- **Grammar**: classic 3-level recursive descent:
+  - `expr → term (('+' | '-') term)*` (lowest precedence)
+  - `term → unary (('*' | '/') unary)*` (medium)
+  - `unary → '-' unary | primary` (right-recursive for stacked unary)
+  - `primary → NUMBER | '(' expr ')'`
+- Left associativity falls out naturally from the `while` loops in `_expr` and `_term`.
+- Unary is right-recursive (`-` `-` 5 → nested Unary) as is conventional.
+- Empty input detected early at `parse()` entry before any descent.
+- Trailing tokens detected after `_expr()` returns, before EOF check.

+  - `tokenize("42")` → `[Token(kind='NUMBER', value=42), Token(kind='EOF', value=None)]`; value is `int`.

+
+- **lex/D3: PASS** @2026-06-15T02:35Z
+  - `"  12  +  3 "` — spaces skipped, yields `NUMBER PLUS NUMBER EOF`. ✓
+  - `"\t"` (tabs) skipped. ✓
+  - `tokenize("1 @ 2")` → `calc.lexer.LexError: unexpected character '@' at position 2` (exit 1). ✓
+  - `"$10"` and `"abc"` also raise `LexError`. ✓
+
+- **lex/D4: PASS** @2026-06-15T02:35Z

+exit code: 1
+```
+
+## Observations (not gate failures)
+
+- `tokenize("1.2.3")` raises `ValueError: could not convert string to float: '1.2.3'` rather than `LexError`. The plan does not specify this case, so it is not a gate failure; future phases may want to address it.
+- STATUS-lex.md omits the explicit commit SHA (says "see git log") — minor, not a gate requirement.

+## D1: PASS @2026-06-15T02:42Z
+
+`*`/`/` bind tighter than `+`/`-`. Cold-run:
+
+```
+1+2*3  → BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))   ✓
+2*3+4  → BinOp('+', BinOp('*', Num(2), Num(3)), Num(4))   ✓
+10-6/2 → BinOp('-', Num(10), BinOp('/', Num(6), Num(2)))  ✓
+```
+
+Grammar verified: `_expr` calls `_term` (which handles `*`/`/`) before combining with `+`/`-` — precedence is structurally encoded, not a test artifact.
+
+---
+
+## D2: PASS @2026-06-15T02:42Z
+
+Left-associativity for all four operators. Cold-run:
+
+```
+8-3-2  → BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))   ✓
+8/4/2  → BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))   ✓
+1+2+3  → BinOp('+', BinOp('+', Num(1), Num(2)), Num(3))  ✓
+```
+
+Associativity comes from `while` loops in `_expr`/`_term` that accumulate left into `node` — correct by construction.
+
+---
+
+## D3: PASS @2026-06-15T02:42Z
+
+Parentheses override precedence. Cold-run:
+
+```
+(1+2)*3   → BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))        ✓
+((4))     → Num(4)                                                   ✓
+2*(3+4)   → BinOp('*', Num(2), BinOp('+', Num(3), Num(4)))        ✓
+```
+
+---
+
+## D4: PASS @2026-06-15T02:42Z
+
+Unary minus: leading, nested, after binary operator, double negation. Cold-run:
+
+```
+-5      → Unary('-', Num(5))                             ✓
+-(1+2)  → Unary('-', BinOp('+', Num(1), Num(2)))        ✓
+3 * -2  → BinOp('*', Num(3), Unary('-', Num(2)))        ✓
+--5     → Unary('-', Unary('-', Num(5)))                 ✓
+```
+
+Adversarial: `---5 → Unary('-', Unary('-', Unary('-', Num(5))))` ✓, `(-5)*3 → BinOp('*', Unary('-', Num(5)), Num(3))` ✓.
+
+---
+
+## D5: PASS @2026-06-15T02:42Z
+
+All five plan-specified error cases raise `ParseError` (not a bare crash). Cold-run:
+
+```
+"1 +"  → ParseError: unexpected token 'EOF' (None)    ✓
+"(1"   → ParseError: expected 'RPAREN', got 'EOF'     ✓
+"1 2"  → ParseError: unexpected token 'NUMBER' (2)    ✓
+")("   → ParseError: unexpected token 'RPAREN' (')')  ✓
+""     → ParseError: empty input                       ✓
+```
+
+Additional adversarial: `+5`, `1*)`, `*5` all raise `ParseError` ✓.
+
+---
+
+## D6: PASS @2026-06-15T02:42Z
+
+```
+python -m unittest -q
+Ran 31 tests in 0.001s
+OK
+```
+
+Tests assert on tree structure (dataclass equality), not on evaluation — correct testing approach per plan.
+
+---
+
+## Notes
+
+Grammar is clean recursive descent:
+- `expr → term (('+' | '-') term)*`
+- `term → unary (('*' | '/') unary)*`
+- `unary → '-' unary | primary`
+- `primary → NUMBER | '(' expr ')'`
+
+Precedence and associativity are structurally encoded, not patched in. No weak tests that would pass a wrong implementation found.
