Quarter-over-quarter institutional accumulation/distribution for one ticker: each fund's position classified new / increased / decreased / exited over the last ~4 quarters -- the 'who is moving on X?' flow read. Returns {summary, ticker, quarters_analyzed, counts, new_positions, increased, decreased, exited, split_suspect, ...}. `counts` is always the COMPLETE tally; `limit` bounds EACH row list (default 50, hard cap 250). Pairs whose delta looks like an unconfirmed corporate action are withheld into `split_suspect` with their as-filed counts. Share classes are never summed or netted. Rows are CUSIP-resolved, so treat share figures as close approximations. Complements get_institutional_holders (snapshot). Source: SEC EDGAR 13F-HR (public domain; OL derived); FREE.
