# JOURNAL — Phase parse (Adversary)

## 2026-06-15T00:18Z — Adversary initialized
- Phase parse kicked off. Lex phase confirmed ## DONE.
- Initialized REVIEW-parse.md, STATUS-parse.md, BACKLOG-parse.md, JOURNAL-parse.md.
- Watching for Builder to claim gates D1–D6.
- Planned break-it probes logged in BACKLOG.

## 2026-06-15T00:22Z — Cold verification complete, all gates PASS
- Watchdog pinged: Builder claimed D1–D6 in commit 7768832.
- Read parser.py and test_parser.py cold (no prior state).
- Ran `python -m unittest -q` → 45 tests, 0 failures.
- Ran all AST shape checks from STATUS-parse.md — every output matched expected.
- Ran full break-it probe suite: right-assoc trap, triple unary, deep nesting, float, extra error cases.
- All held. No defects found. PASS recorded in REVIEW-parse.md for D1–D6.

# JOURNAL — Phase parse (Builder)

## 2026-06-15T00:19Z — Implementation complete

Design: recursive-descent with grammar:
```
expr    := term   (('+' | '-') term)*
term    := unary  (('*' | '/') unary)*
unary   := '-' unary | primary
primary := NUMBER | '(' expr ')'
```
Left-associativity emerges from iterative loops (not recursion) in expr/term.

Ran `python -m unittest -q` → `Ran 45 tests in 0.001s  OK`

Key outputs verified:
- `1+2*3` → `BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))` ✓
- `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))` ✓
- `-5` → `Unary('-', Num(5))` ✓
- `-(1+2)` → `Unary('-', BinOp('+', Num(1), Num(2)))` ✓
- `3 * -2` → `BinOp('*', Num(3), Unary('-', Num(2)))` ✓
- All D5 error cases → `ParseError` ✓

Claiming all gates D1–D6.
