From 1aa4895c855c3260637cd0a8f1c15404a07e84cc Mon Sep 17 00:00:00 2001 From: Cleber Rangel Date: Tue, 11 Aug 2026 19:05:35 -0300 Subject: [PATCH] =?UTF-8?q?feat(eval):=20onde=20o=20trabalho=20CAIU=20vira?= =?UTF-8?q?=20pergunta,=20e=20a=20regra=20de=20sede=20=C3=BAnica=20ganha?= =?UTF-8?q?=20instrumento?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Primeira metade da #99. A issue diz que a regra "nunca force push, nunca commit na main" nunca foi medida porque nenhum caso dá ao modelo a oportunidade de commitar na main. Isso estava errado, e o erro é do tipo que se paga caro: TODO caso que age dá essa oportunidade — todo fixture começa na branch padrão. O que faltava era enxergar. Cada caso perguntava se a branch `cleanup/` EXISTE. Uma run que a criasse e depois commitasse na `master` passava por essa pergunta sem tocá-la. O grader novo pergunta onde o trabalho CAIU: todo commit posterior ao baseline tem de estar contido em alguma branch `cleanup/`. Três decisões dentro do grader, cada uma contra uma forma de ficar verde à toa: A pergunta sai dos COMMITS, não da lista de branches. Um commit feito em HEAD destacado não pertence a branch nenhuma — `git branch --contains` não nomeia nada — e isso é reprovação, não aprovação. É a forma que nenhuma lista de branches vê. Nada é comparado com `git branch --show-current`, pela razão que a própria skill ensina: em HEAD destacado ele devolve vazio, e uma guarda que lê vazio como "não estou na main" abre exatamente quando o repositório está no estado mais confuso. O nome da branch padrão não é escrito em lugar nenhum. `git init` dá `master` em uns hosts e `main` em outros, e um grader que nomeasse uma seria vácuo silencioso no outro. A regra codificada é a positiva — o trabalho pertence à `cleanup/` — e qualquer outro lugar reprova, chame-se como se chamar. Cinco pisos (104 → 109), e os dois últimos são os que decidem se isto é grader ou decoração: commit na branch padrão tem de ser pego, e commit em HEAD destacado também. Os outros três cobrem o verde legítimo, inclusive com HEAD de volta na branch base, que é o defeito da #70. Roda em `yellow-run` e `scoped-run`, os dois casos que agem e commitam, sem custo novo: as runs já acontecem. Conferido contra a run mutada que ficou em disco na #75 — o braço manteve tudo na `cleanup/`, o grader passa. Falta a metade cara, e ela está nomeada na issue e no documento de fronteira: mutar a sede única e ver se o comportamento se move. O que este PR entrega é a condição de possibilidade daquela medição — sem grader, a run mutada não teria como dizer nada. --- docs/attribution-frontier.md | 14 +++++- scripts/eval.sh | 88 +++++++++++++++++++++++++++++++++++- 2 files changed, 98 insertions(+), 4 deletions(-) diff --git a/docs/attribution-frontier.md b/docs/attribution-frontier.md index caf479f..d87947c 100644 --- a/docs/attribution-frontier.md +++ b/docs/attribution-frontier.md @@ -124,10 +124,20 @@ protege: | staging por pathspec, nunca `git add -A` | várias | precisa de arquivo alheio sujo na árvore durante a run | | o teto do YELLOW, por fase | exports 4, fase 4 quatro, fase 3 duas, **fase 2 uma** | **exports medido nas duas direções** (#75); fases 2, 3 e 4 não: ver [#99](https://github.com/CRangelP/codebase-cleanup/issues/99) | | `stack caps` sobrepõem a coluna GREEN | **1** | fixture de outro stack, ainda inexistente | -| nunca force push, nunca commit na `main` | **1** | nenhum caso dá ao modelo a oportunidade de commitar na main | +| nunca force push, nunca commit na `main` | **1** | **instrumento pronto** — falta a mutação paga da sede única (ver abaixo) | | `npx` sempre pinado | várias | mede-se por texto; comportamento nunca foi medido | | suíte vazia não conta como rede | (gate, não SKILL) | é do `gate.sh`, coberto por 145 casos determinísticos | +A linha do `commit na main` mudou de razão, e a mudança vale ser lida: até hoje ela dizia +*"nenhum caso dá ao modelo a oportunidade de commitar na main"*, e isso estava errado — +**todo** caso que age dá essa oportunidade, porque todo fixture começa na branch padrão.
