Comment/XML-doc changes only:
- add summaries to ~10k test methods, fixtures, fakes and helpers
(+ <param> on theories, <returns> on async Task methods,
<inheritdoc/> on interface implementations the checker can resolve)
- strip ~2.6k project-tracking references (WP*, P*-*, row-NN, Task N,
#NN, Component-0NN) from comments, keeping the explanatory text;
reword false positives in comments only
- real docs on fakes implementing BCL/library interfaces
(IDisposable, ILogger, IOptionsMonitor, IAsyncLifetime)
- reword the last 5 src/ false positives (CWE-1236, failures-1,
year-0001, M365)
Only non-comment edits: four one-line nested classes split across lines
so members can carry docs. Build 0 errors / 0 warnings.
Add a third Akka periodic timer (kpi-rollup) to KpiHistoryRecorderActor that
folds the trailing RollupLookbackHours of raw KpiSample rows into the hourly
KpiRollupHourly table via the idempotent FoldHourlyRollupsAsync upsert, with the
in-progress hour excluded (toHourUtc = current hour start, exclusive). A
_rollupInFlight guard coalesces overlapping ticks (mirrors _sampleInFlight), the
fold is best-effort (no exception escapes a tick), and a missed/failover tick
self-heals via the lookback re-fold. The daily purge now runs BOTH the raw
PurgeOlderThanAsync (RetentionDays) and PurgeRollupsOlderThanAsync
(RollupRetentionDays), isolated so one failure never skips the other.
New KpiHistoryOptions: RollupInterval (1h), RollupLookbackHours (3),
RollupRetentionDays (365), RollupThresholdHours (168, consumed by Task 5).
Validator adds bounds incl. the coherence rule RollupRetentionDays >=
RetentionDays so long-range trends have no data hole.
