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.
ExecuteWriteAsync only caught SqlException, so a live outage surfacing as
InvalidOperationException/SocketException/IOException/TimeoutException escaped
unclassified and crashed the script actor instead of buffering. Mirror the HTTP
path: propagate OperationCanceledException on cancellation, classify transport
exceptions as transient (buffer+retry), let unexpected exceptions propagate.
CachedWrite buffered ALL write failures and retried forever, never returning a
synchronous failure to the script — permanent SQL errors (constraint/syntax/
permission) were treated as transient. Mirror the External-System API path:
attempt immediately, return Failed synchronously on permanent SQL errors (no
buffering), buffer only transient errors; the S&F retry path parks permanent
failures instead of retrying forever. New SqlErrorClassifier + PermanentDatabaseException.
