Evidence-Based Code Review: Replacing Subjective Comments with Verifiable AST Signals

Catalayer Code Technical Manual•Updated 2026-10-18•7 min read

Subjective code reviews breed team friction, bikeshedding over formatting, and inconsistent standards. Evidence-based code review replaces opinion with verifiable AST signals, automated consistency checks, and traceable diff evidence.

DETERMINISTIC PRINCIPLES

Evaluation Foundations

01

Rule Assertion

Automate the objective; reserve human review for business logic and architectural tradeoffs.

02

Rule Assertion

Every review comment challenging a change should cite concrete evidence or measurable risk.

03

Rule Assertion

Standardized risk categories de-personalize code critiques.

04

Rule Assertion

Reviewers should spend time understanding domain boundaries rather than hunting for missing semicolons.

Shifting Left with Deterministic Signals

When code inspection runs inside the developer’s browser via the Catalayer Code extension, issues like untested files or oversized diffs are flagged before the pull request is even opened, saving valuable peer review cycles.

BOUNDARY & LIMITS

Explicit Technical Limitations

What this inspection method does not and cannot evaluate.

  • Cannot judge whether a feature fulfills business requirements.
  • Cannot replace human discussions on product UX or domain modeling.

Inspect Any Public GitHub Repository

Run deterministic checks against any public repository without granting OAuth permissions. Review structural gaps, untested changes, and reviewability findings with evidence.

Frequently Asked Questions

How does this integrate with GitHub pull requests?

The Catalayer Code Chrome extension provides an immediate inspection overlay on GitHub PR pages, highlighting risk signals and untested files directly in the browser.
