It performs unstructured document search at scale via the three-layer retrieval protocol (Layer 1→2→2.5→3), escalating to `read_source_deep_outline` only when lightweight labels cannot disambiguate pages, plus structured XBRL where needed. ### 2. Retrieval Strategy Follows the retrieval strategy decision tree in `contracts/retrieval.md`. Primary branch: **(b)/(c) Unstructured Query via the three-layer protocol**. Resolve the canonical ticker first (exact → fuzzy alias → share-class) before any data call. ### 3. Temporal Scope Default lookback: 4 fiscal quarter(s); maximum: 12. The default balances recency against the trend window this analysis requires. ### 4. Tool Allowlist Per frontmatter `allowed_tools`: - `search_companies` — ticker resolution + company context (entity-alias fuzzy match) - `search_xbrl_facts` — primary structured financial facts (is_primary default) - `search_documents` — Layer 1 docu...
