Research — L1 Base Deep Research

Standard research tier. Adds Planner (query decomposition) and per-source summarization on top of quick-research. This is the true foundation of the L1–L5 ladder — every higher level calls this one first, then layers on more.

Position in ladder: L1. Called by L2 (deep-research), L3, L4, L5 as the first stage.

When to Use

• "расскажи про X", "что такое Y", "как работает Z" — non-trivial but not strategic
• Technical overviews of a framework, library, concept
• "что нового в X в 2026"
• Default when user asks for research without specifying depth

Escalate to higher levels if:

• User wants comparison → /deep-research (L2) or /expert-research (L3)
• User wants strategic decision → /expert-research (L3)
• User wants academic rigor → /academic-research (L4)
• User wants a knowledge base → /ultra-research (L5)
