Struct CouplingMemoKey 

pub struct CouplingMemoKey { /* private fields */ }

Memo key for run_coupling. Carries EXACTLY the Options fields that build_coupling_sql, good_commits_cte, source_table, build_total_commits_sql, or the Rust-side Fisher pass branch on — and nothing else. Two Options that agree on every field here produce a byte-identical un-row-limited result, so they may share a memo entry.

Deliberately EXCLUDED: rows_limit (applied as a post-memo Vec::truncate, so the stored result is the full graph regardless of the caller’s --rows N) and every field that only affects ingest or other analyses (after/before/group_file/… are baked into the fact store at ingest time, before any coupling call runs).

fisher_significance is an f64; we key on its raw bit pattern (f64::to_bits) for total, exact-equality hashing — the value flows into the Rust filter fisher_p < opts.fisher_significance, and exact equality is the right notion (the same Options.fisher_significance must map to the same entry; a different one must not collide).
