/**
|
||
* LLM-backed LiveAgent for the live-mode E2E suite.
|
||
*
|
||
* Implements the same interface as createFakeAgent() in
|
||
* tests/live-e2e/agent.mjs: generateVariants(event, context) returns
|
||
* { scopedCss, variants[] }, and applyManualEdits(event, context) returns the
|
||
* production manual-edit Apply result shape. It also implements
|
||
* handleSteer(event, context) for page-level Steer bar messages. The
|
||
* orchestrator handles wrap, write, accept, and carbonize cleanup
|
||
* deterministically.
|
||
*
|
||
* Primary provider/model: Anthropic + Claude Haiku 4.5. DeepSeek V4 Flash is
|
||
* a secondary cheap fallback used only when ANTHROPIC_API_KEY is absent and
|
||
* DEEPSEEK_API_KEY is present, or when explicitly forced with
|
||
* IMPECCABLE_E2E_LLM_PROVIDER=deepseek. Override the model via { model } when
|
||
* constructing, or via IMPECCABLE_E2E_LLM_MODEL at the call site.
|
||
*
|
||
* Prompt caching: live.md (the live-mode skill spec) is the bulk of the
|
||
* system prompt and is stable across calls. We mark a cache_control breakpoint
|
||
* on the last system block so both the JSON-contract instructions and the
|
||
* spec are cached as one prefix. Subsequent calls in the same run pay only
|
||
* the cache-read rate (~0.1× input) when the selected provider honors it.
|
||
*
|
||
* Returns null from createLlmAgent() when the selected provider's API key is
|
||
* unset; the test runner reads that and skips the case rather than failing.
