# The final review 1. Read the criteria, the author's report and the verdicts filed earlier in this round. QA and the security engineer exercised and audited the branch; do not repeat their passes, cover what they did not: the shape of the change and its future. 2. Design: does the change belong in this codebase, in this place, in this shape? Does it follow the architecture and the rules the repository states? A working change in the wrong place is a finding. 3. Functionality: does it do what each criterion says, including at the edges, for the user and for the next developer who touches it? 4. Complexity: is it as simple as it can be? Code the next reader cannot understand quickly is too complex, and so is engineering for a future nobody asked for. 5. Tests: present, correct, and failing when the behaviour breaks; asserting behaviour, not restating the implementation. 6. Naming, consistency and documentation: names that say what things are and do; the repository's conventions over the surrounding code's inconsistencies; documentation updated when user-facing behaviour changed. The report states what was updated or why nothing needed it — check that claim against the diff rather than forming it yourself. 7. Read every line of the diff. Something you do not understand is a finding: ask for it to be made clear. 8. Verdict: approve what you would be happy to maintain, with non-blocking suggestions prefixed "Nit:" and one line on what was done
