# JOURNAL — review phase (Builder)

## 2026-06-16T02:07Z — Phase kickoff

Read review.md plan. This is the final comprehensive verification phase. No new features.

Builder role: initialize phase files, claim, wait for Adversary cold-verify, fix findings, write DONE.

Ran all D3 cross-feature tests locally before claiming:

```
$ python calc.py "-(-(1+2))"
3

$ python calc.py "2+3*4-5/5"
13

$ python calc.py "1 @ 2" 2>&1; echo "exit:$?"
error: unexpected character '@' at position 2
exit:1

$ python calc.py "1/0" 2>&1; echo "exit:$?"
error: division by zero
exit:1

$ python calc.py "(1+" 2>&1; echo "exit:$?"
error: unexpected end of input
exit:1

$ python calc.py "  3.5 * (2.0 + 1.5) "
12.25

$ python calc.py "4/2"
2

$ python calc.py "7/2"
3.5

$ python -m unittest -q
Ran 53 tests in 0.331s
OK
```

All passing. Committing phase files and making claim.
