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.
Reject read the row as Pending, then landed a blind full-row UpdateAsync. A
concurrent approve could win its own Pending->Approved CAS in that gap and enter
the multi-second WriteTagAsync relay; the reject's update then stamped
Status/ExecutedAtUtc/ExecutionError to Rejected mid-relay, so the two-person-control
record said Rejected for a write that physically executed at the plant. Works
cross-node (both centrals share one MS SQL).
- ISecuredWriteRepository/SecuredWriteRepository: new TryMarkRejectedAsync,
mirroring TryMarkApprovedAsync exactly (conditional UPDATE ... WHERE
Status='Pending', writes only the columns the reject transition owns). No schema
change, no migration, no rowversion column.
- HandleRejectSecuredWrite: uses the CAS; on loss re-reads the row and returns the
status that actually won (same UX shape as approve's lost-race error), and emits
the SecuredWriteReject audit row ONLY on a won CAS.
- Audited the other lifecycle writes: approve/reject/expiry (inline + the
opportunistic list sweep) now ALL transition only out of Pending, so winning the
approve CAS gives that leg exclusive ownership of the row and its post-relay
Executed/Failed update stays safe as an unconditional write. Documented in place.
- Tests: repository-level approve-vs-reject races in both orders (exactly one wins,
loser false, row reflects the winner only) plus reject-vs-expiry; handler-level
lost-race reject (conflict error, no write, no audit row) and approve on an
already-rejected row (no CAS, no relay, no audit).
