Do not rate how easily you can follow the code.\nYou can parse compressed code and reconstruct hidden reasoning far more\ncheaply than a person can, and your ease is not evidence of readability.\n\nAssess the submitted changes in the context of the final implementation.\nRate six dimensions from 0 to 4, in increments of 0.5.\nHuman readability:\nnaming: identifiers say what things are in the task's domain; single-letter\nand abbreviated names only where the scope is a few lines and the idiom is\nuniversal;\npresentation: statements per line, expression nesting, function length, and\nhow many values and how much state the reader must track at once; visual\nstructure matches logical structure;\nintent: non-obvious constants, thresholds, quirks, invariants, and\ncompatibility decisions are explained by names or by accurate comments that\nsay why; comments that restate the code count for nothing; comments that\ncontradict the code count against.\nMaintainability:\nstructure: responsibilities, data ownership, and boundaries are coherent; no\nduplicated policy; no abstraction beyond what the task's scale needs;\nchangeability: name one plausible future change (for parity tasks, one\nquirk's threshold or condition changes) and trace every edit site; score by\nhow localized and safe those edits are;\nverifiability: a maintainer can test and diagnose the behaviour: explicit\nrather than hidden module state, failures that name what went wrong, seams to\nexercise one rule without the whole pipeline, no silent fallbacks.\nAnchors, separately for each dimension:\n0 pervasive obstacles require a rewrite for routine maintenance;\n1 substantial obstacles require repeated reconstruction of logic or state;\n2 usable but material localized obstacles complicate maintenance;\n3 clear and maintainable with minor localized shortcomings;\n4 consistently easy to understand and safely change at this task's scale, with\nno material shortcoming supported by the supplied evidence.\nUse intermediate scores only when supported between adjacent anchors.\nNeither brevity nor verbosity is inherently good. Do not demand comments for\nself-evident code, classes, annotations, or unnecessary helper functions.\nFormatting-only issues primarily affect presentation, not every dimension.\nDo not attribute unchanged baseline defects to the candidate. Recovered legacy\nquirks are requirements, not bugs because they look unusual. Do not duplicate\nfunctional grading, security scanning, lint, or complexity scores. Do not infer\nreward hacking or incentives. Do not force scores apart or target a distribution.\nFor every dimension supply an exact nonempty excerpt from the evidence plus a\nconcrete consequence for the reader described above. For changeability name\nthe future change you traced.\nSet the top-level score to 0 as a transport placeholder. Only the six dimension\nscores are authoritative.
