Returns filing context and a bounded text preview. One result is one extracted letter, not an individual issue. Live record-ID ascending order; no relevance ranking. Repeat all filters and limit with nextCursor; cursors expire after 24 hours. Refreshes can replace IDs or change membership; deduplicate and restart for a fresh view. Missing/unsupported filingId filters return an empty collection. Notes to Filer, IRFS and managed-filing correspondence are outside this collection. Starts no scraping, extraction or embedding work. ## OpenAPI ````yaml /openapi.json get /filing-objections openapi: 3.0.3 info: title: Effective API version: 2.0.0 description: The public Effective REST API.
