### Pluggable backends, SQL Server and HistoryUpdate (2026-10)

- **Selection:** `ServerHistorian:Backend` (`Gateway` default | `SqlServer` | `QuestDb`; unknown fails host start). `HistorianBackendRegistry` → `IHistorianBackendProvider` builds all five seams; the gateway keys are only required for `Gateway`. `SqlServer` uses `ServerHistorian:SqlServer:{ConnectionString (required), Schema=hist, CommandTimeout=30s, AutoCreateSchema=true}`.

- **SQL Server** (`Driver.Historian.SqlServer`): `hist.Sample` PK `(TagId, SourceTimeUtc)` — writes are insert-if-absent, so outbox redelivery is idempotent. Stores every value kind with its **real status**; per-sample aggregates (10, simple definitions) are pushed down to T-SQL with bucket math in **100 ns ticks**; the Part 13 time-weighted seven (TimeAverage/TimeAverage2/Total/Total2/Interpolative, #671 — ⚠️ `Total` is now the time-weighted integral, no longer `SUM` — plus the **duration-based** PercentGood/PercentBad, #680, and DurationGood/DurationBad, #820 — ms, Uncertain time in neither; the live AggregateFilter still counts Uncertain as Good, #809) stream window + 4 bound rows into the shared `TimeWeightedAggregator` (both SQL backends, identical results; reverse `Interpolative` anchored at the later time; window capped by `ServerHistorian:MaxTimeWeightedRawRows` ⇒ `BadTooManyOperations`, percentages included). ⚠️ **#680 status rules (client-visible):** TimeAverage/Total are Uncertain if any part of the interval uses an Uncertain value, is bridged across a Bad sample, is extrapolated past the last sample (⇒ a live tag's latest interval is Uncertain) or is not covered; TimeAverage2/Total2 keep the SDK time-based rule (Uncertain time counts as Good) but never extrapolate past the last sample — that interval is Partial, later ones `BadNoData` (a report-by-exception tag with nothing after its last sample reads `BadNoData` until its next sample arrives). `docs/Historian.md` §"Time-weighted aggregates". ⚠️ **#680 per-sample (client-visible):** `Count` counts **Good** samples only (value-based status; an all-Bad interval is generic Bad, value null) and an empty interval **inside the tag's data range** is `0`/Good (outside it still `BadNoData`); `Start`/`End` return the **raw** first/last sample of any quality — its own timestamp and status, value null when Bad; `Delta` is Uncertain only when the interval's first or last sample is unusable; ⚠️ #684: `Average`/`Minimum`/`Maximum`/`Range`/`*ActualTime` use **Good samples only** (was Good + Uncertain; an Uncertain-only interval is `BadNoData`), Min/Max-family status Uncertain on a Bad sample, an Uncertain value beyond the Good extreme (Part 13 — the SDK ignores that) or an Uncertain non-numeric sample, and only a **Good** String/DateTime sample refuses them (`BadAggregateInvalidInputs`; Delta still refuses any usable one); and every per-sample aggregate but `Average` sets **end-of-data Partial** on the interval holding the last sample (forward incl. its earlier edge, reverse strictly inside), never on a Bad result. The data-range lookup is a key seek on SQL Server and a `tag` symbol-index seek on QuestDB (#683 — `{p}sample.tag` is `SYMBOL INDEX`; the bootstrapper ADDs it to a pre-#683 table, idempotent), read BEFORE the bucket statement so a racing append can never yield a Good `Count` of 0 (a concurrent HistoryUpdate delete is the mirror case and still can, transiently). `docs/Historian.md` §"Aggregates".

SDK-parity tests: `SdkAggregateParityTests`. `docs/Historian.md` §Aggregates.
|
||||
- ⚠️ **Reverse / end-only RAW reads work on Gateway (#686, client-visible):** `IHistorianDataSource.SupportsReverseRaw` (SqlServer/QuestDB/Null `true`, Gateway `false`, interface default `false`, guard-tested) — the node manager sends `start > end` only to a backend that declares it; otherwise `ReverseRawReader` serves it from FORWARD reads: uncapped ⇒ ONE forward read reversed in memory; capped ⇒ a bounded walk back in segments (ms-aligned request bounds, width aimed from observed density at ≈ N + 8 rows and carried page to page in the continuation point — #689: it used to aim at half `MaxTieClusterOverfetch`, ~32k rows per page on a dense tag; a read asks for `2N + 18` rows (a discovery segment ≤ 1,026), `MaxTieClusterOverfetch` is only the tie-cluster ceiling — a full read is re-read, never answered truncated; only more than max(1, `MaxTieClusterOverfetch`) samples within ONE MILLISECOND ⇒ `BadTooManyOperations` (per ms, not per timestamp — requests are ms-rounded, and letting a segment narrow below 1 ms stepped a page through one ms a tick per read, ~10k reads); walks no later than now + 1 day and never before the Unix epoch; #691: after two empty segments it asks once for the whole remainder, and the stretch a page proved empty rides the continuation point — the last pages of a deep page-through no longer each walk ~14 reads to 1970). The raw/events tie-path oversized-cluster refusal is now `BadTooManyOperations` too (was `BadHistoryOperationUnsupported`). Uncapped Gateway raw reads (forward too) used to send `max_values = 0`, which the client/gateway reject — now unbounded (`int.MaxValue`; a ceiling refusal ⇒ `BadTooManyOperations`), and a cancelled read is no longer a backend failure. Since #669 such reads failed the node on Gateway and counted as a backend fault (the gateway rejects start > end — `GatewayHistorianDataSource.ReadRawAsync` now refuses one unsent); before #669 an end-only Gateway read returned the OLDEST N ascending — now the latest N at/before EndTime, newest first. Events follow since #691.4: a reverse/end-only capped events read on Gateway (`SupportsReverseEvents` false; Null now reports `true` and answers empty) is walked back the same way (ties sorted by EventId — the gateway orders by time only; one extra event found ⇒ continuation point) — it used to be refused `BadHistoryOperationUnsupported` (explicit reverse) or answered with the OLDEST N ascending (end-only); needs the gateway's `RuntimeDb:EventReadMaxRows` 0/unlimited (it truncates silently). Uncapped Gateway events reads (forward too) used to throw "Array dimensions exceeded" (result list pre-sized to `int.MaxValue`) — fixed. Above a truncated read the walk gallops up from the newest row seen, then bisects (never below 1 ms): a burst that ended 100 days ago ≈ 18 reads, a dense tag that stopped days ago ≈ 26. `docs/Historian.md` §"Open-ended and reverse raw reads".

### #809 — PercentGood / DurationGood count Good time only (owner-approved 2026-11-11)
|
||||
|
||||
The baseline `StatusAggregateCalculator.ComputeDurationGoodBad` counts Uncertain regions as **Good** when `TreatUncertainAsBad = false` (1.5.378.106 and SDK 2.0.1 count Good only). Part 13 §5.4.3.31/§5.4.3.33 (Mantis 0006166) and the HistoryRead evaluators (`TimeWeightedAggregator`, SqlServer + QuestDB) count Good regions only, so live AggregateFilter results disagreed with HistoryRead whenever Uncertain data was present. ScadaBridge uses neither AggregateFilter nor these aggregates.
|
||||
|
||||
- The copied upstream files above are **unchanged** (their SHA-256s still match `baseline-sources.json`).
|
||||
- `GoodOnlyStatusAggregateCalculator.cs` (application code, not a baseline copy) subclasses the baseline `StatusAggregateCalculator` and replaces only the PercentGood / DurationGood computation: the same slice values, simple bounds, stepped regions, empty-slice `BadNoData`, timestamps, value type and Calculated bit, with a region counted as Good only when its status is Good — whatever `TreatUncertainAsBad` says (when true, Uncertain is Bad, so it was never Good). `CompatibilityAggregateFactory.Create` routes exactly those two IDs to it; the other 35 IDs, including DurationBad / PercentBad / WorstQuality, are the baseline unchanged.
|
||||
- Golden test: the 64 vectors this changes (38 PercentGood + 26 DurationGood, all with an effective `TreatUncertainAsBad = false` over data with Uncertain regions) are exempted **exactly** — the PercentGood / DurationGood vectors whose baseline output differs from the same case's baseline vector with `TreatUncertainAsBad = true`, where 1.5.378.182 already counted Good regions only — and each is pinned to that twin's output. The pin is therefore baseline evidence, never regenerated from the application's calculator; any further drift in any of the 6,144 cases fails. `Sdk2AggregateCompatibilityTests.Issue809_*` also pins a hand-computed case.
|
||||
- Live-vs-history parity: `SdkAggregateParityTests.Live_AggregateFilter_PercentGood_and_DurationGood_equal_HistoryRead_over_Uncertain_samples` compares the registered calculator with `TimeWeightedAggregator` over Good / Uncertain / Bad mixes with no masks, and checks that the data discriminates against the pre-#809 baseline.
