Under default adaptive retention, every flush() recomputed total history bytes by walking EVERY committed generation's delta — O(all generations) with disk re-reads past the 4096-entry delta-cache bound. On a production brain with 70,000+ accumulated generations this turned every write into a full-tail scan (60-100s writes, escalating with history growth), even though the free-RAM budget never tripped and nothing was ever reclaimed (SELF-GENERATIONS-GROWTH). historyBytes() now maintains a running total: seeded by one walk on first use, then updated incrementally at both commit paths (+bytes) and the compaction reclaim loop (−bytes), dropped on reopenAfterRestore. The adaptive retention check on every flush is O(1). Invariant regression- pinned: running total ≡ fresh walk through transact commits, single-op group commits, and compaction. New brain.historyStats() (exported HistoryStats): read-only generation count / bytes / generation+timestamp range / horizon / retention mode / effective budget — the one-call per-brain fleet audit for retention exposure. |
