## Description

Step 3 of the PaperOrchestra pipeline (arXiv:2604.05018). Execute the literature search strategy from outline.json, discover candidate papers via web search, verify them through Semantic Scholar (Levenshtein > 70 fuzzy title match, temporal cutoff, dedup by paperId), cross-corroborate against Crossref + OpenAlex to flag hallucinated citations, build a BibTeX file, and draft Introduction + Related Work using ≥90% of the verified pool. Runs in parallel with the plotting-agent. TRIGGER when the orchestrator delegates Step 3 or when the user asks to "find citations for my paper", "draft the related work", or "build the bibliography".

# Literature Review Agent (Step 3)

Faithful implementation of the Hybrid Literature Agent from PaperOrchestra
(Song et al., 2026, arXiv:2604.05018, §4 Step 3, App. D.3, App. F.1 p.46).

**Cost: ~20, 30 LLM calls.** This is one of the two longest steps (the other is
plotting). Wall-time floor is set by Semantic Scholar's 1 QPS verification
limit.

## Inputs

- `workspace/outline.json`, specifically `intro_related_work_plan` with the
  Introduction search directions and the 2-4 Related Work methodology
  clusters
- `workspace/inputs/conference_guidelines.md`, used to derive `cutoff_date`
- `workspace/inputs/idea.md`, `workspace/inputs/experimental_log.md`, for
  framing the Intro and grounding the Related Work positioning

## Outputs

- `workspace/citation_pool.json`, verified Semantic Scholar metadata for
  every paper that survived verification
- `workspace/refs.bib`, BibTeX file generated from the verified pool
- `workspace/drafts/intro_relwork.tex`, drafted Introduction and Related
  Work sections, written into the template, with the rest of the template
  preserved verbatim

## Two-phase pipeline (App. D.3)

```
PHASE 1, Parallel Candidate Discovery
   For each search direction in introduction_strategy.search_directions:
   For each limitation_search_query in each related_work cluster:
     - Use the host's web search tool to discover up to ~10 candidate papers.
     - Run up to 10 discovery queries in parallel (host-permitting).
     - Collect (title, snippet, url) tuples, no verification yet.
   → PRE-DEDUP before Phase 2 (see Step 1.5 below)
