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.
