"""End-to-end LDR pipeline test — runs a real Quick Summary via programmatic API.

Produces the same style of output as the "Quick Summary" mode in the web UI,
but from a single command so we can diff reports against one another (e.g.
same query with arxiv vs openalex). Useful for evaluating the relevance-
filter prompt and synthesis quality in situ.

Usage:
    LDR_BOOTSTRAP_ALLOW_UNENCRYPTED=true LDR_TESTING_WITH_MOCKS=false \\
    pdm run python tests/performance/_shared/run_full_search.py \\
        --query "LLM interpretability latest research" \\
        --engine openalex \\
        --output /tmp/ldr_report_openalex.md

Default model / URL mirror the other dev scripts so a bare invocation with
just --query also works.
