Question
Establish correctness-first performance, memory, cancellation, and determinism coverage for multi-million-observation active-plus-archive histories with high fork duplication. Measure legacy-relative warm and cold behavior without making a fixed speed ratio the primary promotion gate.
Acceptance
Exercise cancellation during root indexing, parsing, graph construction, and reconciliation; prove atomic publication; prove deterministic totals, quality tiers, and family fingerprints under input permutation; and demonstrate that one changed document or newly discovered parent recomputes only affected families when the family-aware cache permits it. Report material regressions for review rather than trading correctness for a target budget.
