Newly discovered links compete with search results in the same +queue. Document scores and link priorities are separate. Links can be +followed at any document score, including across domains.

Unreadable pages and failed +fetches remain unassessed. Duplicate content avoids another LLM call. + +The search is recorded in the jurisdiction's event log, +``/event-logs//events.jsonl``: search results, +visits, HTTP exchanges, scores, parent links, limits, assessment inputs, +model responses, token details, the ranked candidates, and the remaining +queue. No other files are written; fetched pages are kept only for the +documents the pipeline keeps, in ``ordinance_files``. +The SerpAPI subscription price is not allocated to individual searches. +Model costs are estimates using configured ``llm_costs``; missing rates +remain unknown in the per-call metrics. + +The limits apply per jurisdiction. A document found at the final depth +is still assessed, but its links are not added. The crawler continues +after finding a strong candidate so that amendments can also be found. +Set ``perform_website_search`` to ``false`` to avoid running the separate +legacy website-crawl steps after this bounded search.
