Crypto ETF Sentinel — Chronological profile evolution for one US spot crypto ETF issuer: custodian, fee, AP-count and in-kind deltas across successive POS AM filings. Use when tracing how a fund's terms changed over time (fee cuts, custodian switches). Pass the issuer's SEC CIK as cik; optional limit.

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
