A criacao de API key descartava a ACL enviada no payload; preservar essa ACL exige carregar e persistir o conjunto no mesmo chokepoint de INSERT do modulo de dominio, sem extracao possivel sem partir a funcao de criacao ao meio. Coberto pelos testes do proprio PR (54/54 focados na leva).",

Cada PR registrou o proprio crescimento contra o tip de onde forkou (o #12637 ja subira o cap para 4075); as 5 linhas restantes so aparecem quando eles empilham, porque mais de um toca o mesmo chokepoint de scoring reset-aware em combo.ts.

Two of my own PRs on top of #12867: #12963 pins the ok variant of the non-streaming leg result in its own binding (the discriminated-union narrowing was lost across the tool-loop reassignment, 13 TS2339 under tsconfig.typecheck-api.json), and #12990 restores four behaviours the same refactor dropped — abort classification through isLocalStreamLifecycleError, the omitted synthetic clientResponse, the claudePromptCacheLogMeta rebuild on the leg path, and the lazy fail-closed fence identity. Irreducible at the existing chokepoints: each edit sits where chatCore already owns the decision, and the helpers themselves (nonStreamingProviderLeg.ts, serverOwnedToolLoopWire.ts) are under cap. Covered by tests/unit/chatcore-translation-paths.test.ts (72/74; the 2 open are issue #13043)."
