- I-1: QuestDbConnection caps Npgsql Maximum Pool Size at 24 (DefaultMaxPoolSize) when the connection string does not set it; an explicit value is kept. The effective value is logged once at Information. - M-1: QuestDbTagCatalog.EnsureAsync waits for the tag table's sequenced commits and re-checks before inserting, so it no longer overwrites a provisioner row (unit/description) that is committed but not yet applied. Integration test reproduces the clobber against real QuestDB (falsified). - M-3: the pre-1970 drop Warning is rate-limited per tag (once per 10 min); DroppedPre1970 still counts every sample. - M-5: QuestDbHistorianProvider is IAsyncDisposable/IDisposable and disposes the shared Npgsql pool; Program.cs registers the provider through a factory and every seam resolves it from the container, so DI disposes it at shutdown. - M-8, M-9: docs fixes (HistoryUpdate transaction wording; folded duplicate HistoryUpdate paragraph). Pool-size docs updated for the new default cap. Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
