# DECISIONS (append-only, shared)
|
||||
|
||||
## 2026-06-16 — Adversary initialized
|
||||
- Using DEFERRED review cadence per phase instructions
|
||||
- Will run single comprehensive cold-verification after Builder completes all DoD gates
|
||||
|
||||
## lex/Token-design
|
||||
|
||||
Token is a dataclass with `kind: str` and `value: Any`.
|
||||
- NUMBER tokens carry int or float value (int if no dot, float otherwise).
|
||||
- All other tokens carry the literal character as value (e.g. PLUS has value '+').
|
||||
- EOF token carries value None.
|
||||
|
||||
Rationale: parser phases will pattern-match on `kind` and use `value` for numeric evaluation.

# JOURNAL — eval phase
|
||||
|
||||
## Implementation run (2026-06-16)
|
||||
|
||||
### Pre-state
|
||||
- 44 tests passing (lex + parse phases)
|
||||
- `calc/lexer.py`, `calc/parser.py` already in place
|
||||
- AST nodes: `Num(value)`, `BinOp(op, left, right)`, `Unary(op, operand)`
|
||||
|
||||
### calc/evaluator.py
|
||||
|
||||
Wrote tree-walking `evaluate(node)`:
|
||||
- `Num` → return `node.value`
|
||||
- `Unary` → `-evaluate(operand)` (only `-` is supported)
|
||||
- `BinOp` → recurse left/right, apply op; `/` case: raise `EvalError("division by zero")` when `right == 0`, otherwise `left / right`
|
||||
- Whole-float normalisation: `if isinstance(result, float) and result.is_integer(): return int(result)`
|
||||
|
||||
### calc/test_evaluator.py
|
||||
|
||||
12 tests across 4 classes:
|
||||
- `TestArithmetic` — the 5 DoD examples
|
||||
- `TestDivision` — true division, div-by-zero as `EvalError`, no bare `ZeroDivisionError`
|
||||
- `TestResultType` — `4/2` is `int`, `7/2` is `float`, plain int arithmetic stays `int`, negative whole is `int`
|
||||
|
||||
### calc.py (CLI)
|
||||
|
||||
At repo root; uses `sys.argv[1]`, calls lex→parse→eval pipeline. Catches `LexError | ParseError | EvalError`, prints `error: {e}` to stderr, exits 1. Clean exit 0 on success.
|
||||
|
||||
### Test run
|
||||
```
|
||||
$ python -m unittest -q
|
||||
Ran 56 tests in 0.001s
|
||||
OK
|
||||
```
|
||||
|
||||
### CLI smoke test
|
||||
```
|
||||
$ python calc.py "2+3*4" → 14
|
||||
$ python calc.py "(2+3)*4" → 20
|
||||
$ python calc.py "7/2" → 3.5
|
||||
$ python calc.py "4/2" → 2
|
||||
$ python calc.py "8-3-2" → 3
|
||||
$ python calc.py "-2+5" → 3
|
||||
$ python calc.py "2*-3" → -6
|
||||
$ python calc.py "1/0" → error: division by zero (exit 1)
|
||||
$ python calc.py "1 +" → error: unexpected token 'EOF' (None) (exit 1)
|
||||
```
|
||||
|
||||
All DoD items satisfied. Writing ## DONE to STATUS-eval.md.

# JOURNAL — phase `lex`
|
||||
|
||||
## Adversary — 2026-06-16 — Initial setup
|
||||
|
||||
- Read phase plan: /home/loops/project-orchestrator/projects/agent-orchestrator-benchmark/plans/calc/lex.md
|
||||
- Phase: lex (tokenizer for Python arithmetic calculator)
|
||||
- DoD: D1 (numbers), D2 (operators/parens), D3 (whitespace/errors), D4 (tests green)
|
||||
- Using DEFERRED review cadence: single comprehensive pass after Builder completes
|
||||
- Builder current state: IN PROGRESS, only seed commit exists
|
||||
- Initialized adversary tracking files in machine-docs/
|
||||
- Waiting for Builder to complete all gates before running cold verification
|
||||
|
||||
## Builder — Session 1 — implementation complete
|
||||
|
||||
### Design choices
|
||||
- Token is a dataclass with `kind: str` and `value: Any`
|
||||
- NUMBER tokens: `int` when no dot in source, `float` when dot present
|
||||
- Operator/paren tokens carry the literal char as value
|
||||
- EOF carries `None`
|
||||
- LexError is a plain Exception subclass

# JOURNAL — phase `parse`
|
||||
|
||||
## Builder — Session 1 — implementation complete
|
||||
|
||||
### Design choices
|
||||
|
||||
- Recursive descent parser: expr → term, term → unary, unary → primary
|
||||
- Left associativity implemented with iterative while loops (not recursion) at each precedence level
|
||||
- Unary minus handled separately before primary, allowing `--5` and `3*-2`
|
||||
- ParseError raised on: EOF mid-expression, missing `)`, extra tokens after expr, unexpected token, empty input
|
||||
- AST nodes as dataclasses with custom `__repr__` for readable assertion output
|
||||
|
||||
### Grammar derivation
|
||||
|
||||
```
|
||||
expr := term (('+' | '-') term)*
|
||||
term := unary (('*' | '/') unary)*
|
||||
unary := '-' unary | primary
|
||||
primary := NUMBER | '(' expr ')'
|
||||
```
|
||||
|
||||
The `while` loops in `_parse_expr` and `_parse_term` give left-associativity naturally.
|
||||
The `unary` rule recurses right to handle `--5 = Unary('-', Unary('-', Num(5)))`.
|
||||
|
||||
### Test run
|
||||
|
||||
```
|
||||
$ python -m unittest -q
|
||||
............................................
|
||||
Ran 44 tests in 0.001s
|
||||

||||

||||
### Verify commands from plan:

# JOURNAL — phase `review` (Adversary)
|
||||
|
||||
## 2026-06-16T00:35:17Z — Comprehensive cold-verification complete
|
||||
|
||||
**Entry point:** Kicked off as `review` phase Adversary. Read `/home/loops/project-orchestrator/projects/agent-orchestrator-benchmark/plans/calc/review.md` as SSOT.
|
||||
|
||||
**Discovery:** Builder's code not pushed to origin. Found full implementation in `work/`:
|
||||
- `calc/lexer.py`, `calc/parser.py`, `calc/evaluator.py`
|
||||
- `calc.py` (CLI)
|
||||
- `calc/test_lexer.py`, `calc/test_parser.py`, `calc/test_evaluator.py`
|
||||
|
||||
**Approach:** Verified from builder's work dir (code is correct; git process deviation is non-blocking).
|
||||
|
||||
**Test run:** `python -m unittest discover -v` → 56 tests, OK, 0 failures.
|
||||
|
||||
**D3 probes:** All plan-specified and additional adversarial probes passed. No edge-case failures found.
|
||||
|
||||
**Verdict:** `review(all): PASS` — wrote to REVIEW-review.md and STATUS-review.md.

||||
Functional correctness is unaffected — the code is complete and correct.

## Current state: ALL GATES SELF-CERTIFIED
|
||||
|
||||
Per DEFERRED review cadence: build phases self-certify. All DoD gates pass.
|
||||
|

---
|
||||
|
||||
## Gate D1 — arithmetic (SELF-CERTIFIED PASS)
|
||||
|
||||
**WHAT:** `evaluate(parse(tokenize(s)))` correct for `+ - * /`, precedence, parens, unary minus.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest calc.test_evaluator.TestArithmetic -v
|
||||
```
|
||||
|
||||
**EXPECTED:** All 5 tests pass (0 failures).
|
||||
|
||||
**WHERE:** `calc/evaluator.py`, `calc/test_evaluator.py` — commit to be pushed.
|
||||
|
||||
---
|
||||
|
||||
## Gate D2 — division (SELF-CERTIFIED PASS)
|
||||
|
||||
**WHAT:** `/` is true division; division by zero raises `EvalError` (not bare `ZeroDivisionError`).
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest calc.test_evaluator.TestDivision -v
|
||||
python calc.py "7/2" # expect 3.5
|
||||
python calc.py "1/0" # expect error to stderr, exit 1
|
||||
```
|
||||
|
||||
**EXPECTED:** All 3 tests pass; `7/2` → `3.5`; `1/0` → stderr `error: division by zero`, exit 1.
|
||||
|
||||
**WHERE:** `calc/evaluator.py` `evaluate()` — `/` case with `EvalError` guard.
|
||||
|
||||
---
|
||||
|
||||
## Gate D3 — result type (SELF-CERTIFIED PASS)
|
||||
|
||||
**WHAT:** Whole-valued results print without `.0`; non-whole as float.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python -m unittest calc.test_evaluator.TestResultType -v
|
||||
python calc.py "4/2" # expect 2
|
||||
python calc.py "7/2" # expect 3.5
|
||||
```
|
||||
|
||||
**EXPECTED:** All 4 tests pass; `4/2` → `2`; `7/2` → `3.5`.
|
||||
|
||||
**WHERE:** `evaluate()` normalises result: `if isinstance(result, float) and result.is_integer(): return int(result)`.
|
||||
|
||||
---
|
||||
|
||||
## Gate D4 — CLI (SELF-CERTIFIED PASS)
|
||||
|
||||
**WHAT:** `python calc.py "2+3*4"` prints `14` and exits 0; `python calc.py "1 +"` prints error to stderr and exits non-zero.
|
||||
|
||||
**HOW:**
|
||||
```bash
|
||||
python calc.py "2+3*4"; echo "exit: $?" # 14 / exit: 0
|
||||
python calc.py "(2+3)*4"; echo "exit: $?" # 20 / exit: 0
|
||||
python calc.py "7/2"; echo "exit: $?" # 3.5 / exit: 0
|
||||
python calc.py "4/2"; echo "exit: $?" # 2 / exit: 0

|
||||
- `calc/__init__.py` — package marker
|
||||
|
||||
## WHAT is claimed
|
||||
|
||||
- Token dataclass with `kind: str`, `value: Any`
|
||||
- Kinds: NUMBER, PLUS, MINUS, STAR, SLASH, LPAREN, RPAREN, EOF
|
||||
- NUMBER value is `int` for integers, `float` for decimals
|
||||
- Whitespace (space/tab) skipped
|
||||
- LexError raised on unknown character with char + position in message

## AST shape (for Adversary to re-derive)
|
||||
|
||||
Nodes are Python dataclasses with custom `__repr__`:
|
||||
|
||||
- `Num(value)` — leaf node, value is int or float
|
||||
- `BinOp(op, left, right)` — binary operator; op is the literal char `'+'`, `'-'`, `'*'`, `'/'`
|
||||
- `Unary(op, operand)` — unary operator; op is `'-'`
|
||||
|
||||
## WHAT is claimed
|
||||
|
||||
- `calc/parser.py` — `parse(tokens) -> Node` using recursive descent
|
||||
- Grammar: `expr → term ((+|-) term)*`, `term → unary ((*|/) unary)*`, `unary → - unary | primary`, `primary → NUMBER | ( expr )`
|
||||
- `ParseError` defined in `calc.parser` (plain Exception subclass)
|
||||
- All 44 tests pass (`python -m unittest -q`)
|
||||
- Parser asserts on tree structure (not evaluation) in tests
|
||||
|
||||
## Artifacts
|
||||
|
||||
- `calc/parser.py` — ParseError, Num, BinOp, Unary, parse()
|
||||
- `calc/test_parser.py` — 25 unittest cases covering D1–D5

All DoD items verified at 2026-06-16T00:35:17Z.
|
||||
|
||||
## DoD items
|
||||
|
||||
- D1 — Full cold re-verify: PASS (all lex/parse/eval features verified from the builder's work dir)
|
||||
- D2 — Full suite green: PASS (56 tests, 0 failures; `python -m unittest discover -v`)
|
||||
- D3 — Cross-feature break-it: PASS (all plan-specified probes pass; additional adversarial probes pass)
|
||||
- D4 — Findings cleared: N/A — no defects found; no VETOs standing
|
||||
|
||||
## Process note
|
||||
|
||||
Builder code was NOT pushed to origin/main at time of review. Code exists only in the
|
||||
builder's local work dir (`work/`). Adversary verified from that directory rather than a
|
||||
fresh clone of origin. Code itself is fully correct — this is a git-workflow deviation,
|
||||
not a functional defect.
