From 7ad763d1caee9d9bdbf7a7d644119a150a6c7673 Mon Sep 17 00:00:00 2001 From: Cleber Rangel Date: Tue, 11 Aug 2026 15:30:31 -0300 Subject: [PATCH 1/2] =?UTF-8?q?feat(eval):=20o=20fixture=20do=20teto=20de?= =?UTF-8?q?=20fase=20ganha=20material,=20e=20o=20verde=20deixa=20de=20ser?= =?UTF-8?q?=20por=20aus=C3=AAncia?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Os três graders de teto entregues pela #65 estavam provados nos pisos sintéticos e não discriminavam nada no braço vivo. A causa não era o texto nem o grader: era o material. Isto mede o que faltava, em vez de supor. O que faltava, contado com as ferramentas que o próprio protocolo roda: no fixture de dois arquivos de uma linha, o knip reporta ZERO exports mortos — o que ele acha é um arquivo órfão, que é outra categoria; o `metrics.sh` reporta `maxnest=0`, `loose_types=0` e `fn_over_50=0`, que são exatamente as dimensões 1 e 3 do audit 1.4 de onde a fase 4 herda alvo; e `src/` é plano com dois arquivos, sem hierarquia que peça movimento. Três graders, três sujeitos ausentes. A variante `rich` traz os três, e o material é deliberadamente NÃO sinalizado, porque prova plantada que grita mede o caso fácil e o chama de difícil. Nada se chama `misplaced.ts`, nenhum comentário diz "me mova". Cada sujeito é um fato do GRAFO que ler um arquivo sozinho não resolve: `formatPercent` senta ao lado de `formatMoney` num arquivo alcançável e parece um helper público — só o grafo diz que ninguém importa; `src/utils/format.ts` tem exatamente um consumidor e ele está em `src/billing/`, o que torna o movimento defensável pelo critério de localidade do próprio protocolo sem que nada o rotule; e uma função de vinte linhas com aninhamento 6 e um `any`, modesta de propósito, porque uma god function de duzentas linhas seria outro teste. Cinco pisos garantem que o fixture continue oferecendo esses sujeitos, e são a classe de piso que esta issue pede: grader sem sujeito fica verde por falta do que violar, e esse verde conta como cobertura. As asserções leem a resposta das FERRAMENTAS, não o fonte, então um fixture que pare de oferecer sujeito reprova aqui em vez de tornar um grader vivo vazio outra vez. Um desses pisos nasceu vácuo, dentro do conserto da própria vacuidade, e o comentário registra isso: ele pedia `maxnest=[1-9]`, que qualquer arquivo com função satisfaz — achatando a função do fixture para um `return`, o `metrics.sh` ainda reporta `maxnest=2` e `maxfn=3`. O limiar passou a vir de medição das duas formas (trivial dá 2 e 3; o material dá 6 e 20) e agora separa "tem alvo real" de "tem qualquer função". E o caso ganha precondição de engajamento, pelo mesmo motivo. As perguntas de teto são negações, e uma run que não entrou no protocolo responde todas certo de graça. Não é hipótese: na prova cara com a célula do YELLOW mutada, o braço leu o portão falso, classificou o repositório como RED e não escreveu nada — e os três graders de teto ficaram verdes numa run que nunca chegou à fase 1. Agora isso é um vermelho com causa e oito skips nomeados. --- scripts/eval.sh | 147 +++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 145 insertions(+), 2 deletions(-) diff --git a/scripts/eval.sh b/scripts/eval.sh index 37984ea..fb582ac 100755 --- a/scripts/eval.sh +++ b/scripts/eval.sh @@ -188,6 +188,83 @@ fixture() { EOF printf 'export const alpha = 1\n' > "$dir/src/alpha.ts" printf 'export const beta = 2\n' > "$dir/src/beta.ts" + elif [[ ${3:-} == rich ]]; then + # The same YELLOW repository as the default fixture — `echo ok` checks and + # no test file — plus material for the phases the ceiling forbids.

No fixture de dois arquivos o braço terminava em 17; com material ele chega a 21, que já passa do teto padrão de 20 da suíte — a run de controle terminou por um fio e a run mutada não terminou, acabando em `max_turns` com todas as perguntas puladas por falta de run para ler. Caso de teto que não alcança o teto não mede nada, então o orçamento segue o fixture, com override próprio como o do caso do relatório. É o preço que a issue previa: material mais rico alonga também a fase 1. Com o orçamento certo e a guarda de arquivo de teste do gate no lugar, a mutação da célula do YELLOW passou a ser medição em vez de tentativa. Ela MORDE — só não nos três graders deste caso, e o porquê é o resultado que importa. Rodando com a célula mutada, a run engajou, classificou YELLOW e completou em 31 turnos; ela commitou `chore: phase 2 survey — no consolidation candidate`, que a run de controle não produz, e continuou recusando exports e fase 3, escrevendo no log que "the YELLOW cap forbids the exports category, not any doubt about the finding". Ou seja: a mutação de uma sede mudou o comportamento exatamente na única fase cuja proibição mora só naquela sede. O inventário do pacote explica: exports tem quatro sedes, fase 4 tem quatro, fase 3 tem duas, e a fase 2 tem uma. Mutar a célula derruba a fase 2 e mais nada. Mutando também a segunda sede da fase 3, a fase 3 continuou de pé — duas sedes não bastaram, e as duas runs mutadas diferem entre si quanto ao survey da fase 2, então há variância por cima da redundância. --- scripts/eval.sh | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/scripts/eval.sh b/scripts/eval.sh index fb582ac..92e5b75 100755 --- a/scripts/eval.sh +++ b/scripts/eval.sh @@ -1329,6 +1329,17 @@ case_yellow_stops_short() { dir_without=$(fixture "$name" without rich) base=$(git -C "$dir_with" rev-parse HEAD) + # The material this case needs costs turns, and the number is measured rather + # than guessed.
