> ⚠ Low confidence — Each summary sentence is tied to a verbatim excerpt and model-checked; completeness and independent factual correctness remain unverified. Evidence assessment: 2 sub-claims remain below the evidence threshold. Treat this as provisional.
Model-written summary with sentence-level citations. Each sentence is followed by the verbatim source text it was checked against; sentences without a qualifying excerpt were removed.

Evidence gap: no qualifying excerpt for this research target.
Summary sentences are model-written and model-checked, not independently verified; they claim no more than their excerpts and are not a complete synthesis. Excerpts establish source grounding, not that a source is correct. Source statements may be wrong or conflicting. Payment states remain in the separate receipt.

Research evidence matrix
Compare unverified research targets with cited sources and inspect recorded excerpts. An empty cell means no inspectable excerpt was recorded; it does not establish whether a claim is true, false, or disputed. Coverage and agent confidence do not prove entailment, measured accuracy or complete synthesis.

Identified 4 research target(s) to investigate; these are not established facts
Quick mode: at most 2 paid/cached/public reads, with no marketplace probe or gap-expansion round.
Supplied source URL https://developer.mozilla.org/pt-BR/docs/Web/HTML/Reference/Elements/button admitted as an unread discovery lead. No official authorship or evidence established; a supplied fragment requests a section but only a bounded whole-document read is supported.
Web search: 2/2 planned queries attempted, 1 succeeded, 8 public page previews/leads, 1 unavailable queries. Previews and supplied URLs are discovery only. Public reads spend no USDC; model and service operating costs remain separate.
Discovered 2 verified creator source(s) and 38 free public reference(s)

Final check — "Segundo a página indicada da MDN, qual é o comportamento de …": 100% assessed by S1
Final check — "Segundo a página indicada da MDN, qual é o comportamento pad…": 0% assessed
Final coverage assessment — A página fornecida da MDN contém uma passagem que descreve explicitamente os comportamentos de type="reset" e type="button", mas não inclui uma descrição explícita do comportamento de type="submit" nem do comportamento padrão quando type não é informado. Portanto, apenas as subafirmações sobre reset e button estão diretamente cobertas; as demais permanecem sem resposta no material disponível. The assessment does not establish a complete supported answer for every requested part.
