The pipe layer of an AI nervous system: one interface connecting provider neurons to your application, across three inference types — generate, stream and decide. `decide` returns typed, calibrated judgements from a non-generative model (~400ms, ~$0.00002

/**
 * Drives the Anthropic -> Codex response/stream codec against a real upstream
 * `Response`. Mirrors `codexFallback.ts`, inverted: named after its own
 * upstream, an Anthropic-shape engine, by the same convention `codexFallback.ts`
 * is named after Codex.
 *
 * Scope: translation and the pre-commit/post-commit boundary only. Engine
 * selection, OAuth/account selection, retry/cooldown policy and analytics
 * recording are owned by sibling modules and are not this module's concern —
 * it does not touch `src/lib/server/routes/codexProxyRoutes.ts`.
 *
 * SSE parsing note: this direction reads Anthropic-shaped SSE bytes, the same
 * wire shape `preflightAnthropicStream` already buffers before this module
 * ever sees the stream. Rather than duplicating `codexFallback.ts`'s
 * carry/searchFrom scanner (built for the differently-shaped native Codex
 * event vocabulary), this module reuses `extractSSEEvents` — the incremental
 * Anthropic-SSE parser `preflightAnthropicStream` itself is built on — so the
 * preflight-buffered chunks and the live remainder are parsed by the exact
 * same code path. The carry/searchFrom scanner extraction into a shared
 * `sseFrameScanner.ts` remains an explicitly-deferred follow-up either way.
