Direct answer to “How does AppTruth compare with code review, testing, and security scanners?”

AppTruth explains source-backed product behavior across a repository. Code review evaluates implementation quality and change intent; automated tests execute encoded assertions; security scanners look for risk patterns or exploitable behavior; observability reports live-system telemetry. Teams use them together because no method produces all of those evidence types.

Key points: How does AppTruth compare with code review, testing, and security scanners?

Choose tools by the question and evidence required.
AppTruth is strongest at cross-stack behavior explanation from source.
Runtime and specialist checks remain necessary for release assurance.

When should you use AppTruth instead of a conventional code review?

Use AppTruth when the immediate need is a plain-language map of what the repository supports across several files or systems. Use a conventional code review when maintainers must judge a specific change, design choice, maintainability concern, or team convention.

The two can reinforce each other: an AppTruth finding can focus reviewer attention, while human review can evaluate nuance and intent that static analysis cannot establish.

Why can tests pass while important behavior is still wrong?

Tests prove only the assertions, data, environment, and paths they execute. A missing assertion, unrealistic fixture, incomplete negative case, or different production configuration can leave a gap. Behavior mapping helps identify which assumptions deserve tests.

Why does AppTruth not replace a security scanner?

Security tools are designed around threat classes, known weaknesses, dependencies, runtime attack surfaces, and reproducible exploits. AppTruth may identify security-relevant behavior, but it does not claim exhaustive vulnerability detection or certification.

App verification methods compared by evidence

No row is universally best; the release question determines the method.
Method	Primary evidence	Does it run the app?
AppTruth	Cross-stack behavior grounded in source	No
Human code review	Change intent, design, and maintainability judgment	Usually no
Automated testing	Pass or fail against encoded assertions	Yes
SAST or dependency scanner	Known source or package risk patterns	No
DAST or penetration test	Observed runtime security behavior	Yes
Observability	Telemetry from a running system	Yes

The QUESTION-to-PROOF Matrix

A tool-selection framework that begins with the decision instead of the product category.

Question: Write the exact uncertainty blocking the decision.
Proof: Define the evidence that would resolve it.
Method: Choose the source, runtime, security, or operational method that creates that evidence.
Boundary: Record what the selected method still cannot establish.
