/**
 * Capture attribution, then register a retrieval-log write.
 * @param projectRoot - Explicit owning project root.
 * @param query - Original search query or exact fetched identity list.
 * @param entryIds - Returned evidence identities copied before asynchronous work.
 * @param source - Existing retrieval path label retained in the log.
 * @param tokensUsed - Existing estimated token count, without recalculating policy.
 * @returns Completion of session capture and scheduling, not a durable telemetry receipt.
 * @remarks Reads are pure (T13947): only `brain_retrieval_log` is written,
 * never the returned memory rows. Bumping `citation_count`/`updated_at` on every
 * read made whatever ranked first get cited, promoted and ranked again. The
 * writer retains the original operation lifetime; no global session is resolved
 * after scheduling; underlying telemetry failures remain best-effort.
 * @example
 * ```ts
 * await scheduleRetrievalTelemetry(projectRoot, 'auth', ['O-example'], 'find', 50);
 * ```
