Each finding is a focused validation guard or upper bound at a trust boundary.
Highlights:
- Commons-015: EncryptionMetadata ctor now validates Algorithm (AES-256-GCM
only), Kdf (PBKDF2-SHA256 only), Iterations ([100k, 10M]), non-null Salt/IV.
- Transport-004: new BundleUnlockRateLimiter (sliding-window, per-key,
singleton) wired into BundleImporter.LoadAsync; over-budget callers see
BundleUnlockRateLimitedException. Per-bundle 3-strike + per-window cap.
- ESG-022: ExternalSystemClient.InvokeHttpAsync allow-lists the documented
GET/POST/PUT/PATCH/DELETE set (case-insensitive); unknown verbs throw.
- SEL-015: SiteEventLogger queue now bounded (10k cap, DropOldest); dropped
events fault their Task and increment FailedWriteCount so the drop is
observable instead of an unbounded memory growth.
- SEL-017: EventLogQueryService clamps caller-supplied PageSize to a new
MaxQueryPageSize cap (default 500) so int.MaxValue can't OOM the host.
- SEL-020: LogEventAsync rejects severities outside {Info, Warning, Error}
(matches SQLite BINARY-collation query filter).
- InboundAPI-020: ContentType "json" check now case-insensitive
(application/JSON no longer slips through as not-json).
- InboundAPI-024: _knownBadMethods capped at 1000 entries (drops new entries
once full); per-request DB lookup remains the correctness path.
- SR-025: HandleSetStaticAttribute validates the attribute name against the
deployed config; unknown names now return Success=false instead of
leaking orphan override rows into the SQLite store.
- TE-021: MoveTemplateAsync runs the sibling-name-collision check at the
destination, mirroring TemplateFolderService.MoveFolderAsync.
- TE-022: LockEnforcer's once-locked-stays-locked rule now also covers
LockedInDerived (was previously only IsLocked).
New regression tests across 8 test projects (EncryptionMetadata, rate
limiter, ESG client allow-list, SEL bounded channel / PageSize clamp /
severity validation, InboundAPI ContentType + bad-methods cap, SiteRT
unknown-attribute, TemplateEngine MoveTemplate + LockedInDerived).
Build clean; affected suites all green. README regenerated: 93 open (was 104).
Note: a separate manual re-run was needed for the SiteEventLogging hunk
because its initial subagent's source edits never landed on disk despite
reporting success (file-collision-style failure mode).
UTC invariant + culture-safety fixes across UI form binding, audit entity
hydrate, and locale-dependent parses. Highlights:
- CentralUI-026/027: AuditFilterBar / SiteCallsReport / NotificationReport /
EventLogs now apply SpecifyKind(Local) + ToUniversalTime() at form submit
so browser-local datetime-local inputs aren't silently treated as UTC.
- Commons-019: AuditEvent.OccurredAtUtc / IngestedAtUtc init-setters
re-tag any incoming DateTime as Kind=Utc, documenting the invariant.
- CD-018: AuditLogEntityTypeConfiguration adds UTC ValueConverters on the
*Utc DateTime columns so EF hydrate yields Kind=Utc (SQL Server's
datetime2 has no Kind metadata, so reads were returning Unspecified).
- CD-020: GetPartitionBoundariesOlderThanAsync now SpecifyKind(Utc) on the
raw-ADO read, matching the existing defence in AuditLogPartitionMaintenance.
- SEL-021: EventLogQueryService.DateTimeOffset.Parse now uses
InvariantCulture + AssumeUniversal | AdjustToUniversal.
- SR-023: Convert.ToDouble in ScriptActor + AlarmActor (4 sites) now
passes InvariantCulture so non-US locales don't mis-parse string values.
- HM-020: CentralHealthAggregator.MarkHeartbeat anchors LastHeartbeatAt to
max(receivedAt, now) on offline→online so a stale receivedAt can't
leave a recovered site one tick from re-going-offline.
3 new tests added (AuditLog UTC converter, AuditFilterBar/EventLogs/
NotificationReport-touching CentralUI tests already cover Apply paths,
heartbeat offline→online). Build clean; ConfigurationDatabase 236,
Commons 330, HealthMonitoring 71, SiteRuntime 301, SiteEventLogging 50,
CentralUI 50 — all green. README regenerated: 104 open (was 112).
CD-015: rewrite NotificationOutboxRepository.InsertIfNotExistsAsync as raw-SQL
IF NOT EXISTS … INSERT with SqlException 2601/2627 catch, ending the
at-least-once livelock on the site→central notification handoff.
DCL-018/019/020/021/022: add _subscribesInFlight guard so concurrent
same-tag subscribes don't orphan an adapter handle; delete the latent
dead _subscriptionHandles dictionary; stop double-counting
_totalSubscribed when an unresolved tag is promoted via another instance;
release adapter handles on mid-flight unsubscribe; gate the
tag-resolution retry timer with IsTimerActive so subscribe bursts don't
reset it into starvation.
SR-020: add _terminatingActorsByName shadow so a third deploy arriving
during a pending redeploy doesn't crash on InvalidActorNameException —
displaced senders get a Failed/superseded response and the latest
command wins on Terminated.
SR-024: split OperationTrackingStore reads from writes (fresh
SqliteConnection per GetStatusAsync) so long writes don't block status
queries; rewrite Dispose to drop the sync-over-async bridge that could
deadlock on a non-reentrant SyncContext; Interlocked.Exchange makes the
dispose-once flag race-safe across both paths.
Re-applies the full 10-category checklist to every src/ project — including
first-time reviews of the four newer components (AuditLog, NotificationOutbox,
SiteCallAudit, Transport) — so the code-reviews/ index reflects today's
codebase rather than the 2026-05-16 baseline. 172 new Open findings (0
Critical, 18 High, 62 Medium, 92 Low); 481 findings total across 23 modules.
regen-readme.py now derives each module's Last reviewed + Commit from its
findings.md header instead of hard-coding 2026-05-16 / 9c60592, so future
single-module re-reviews show their own date in the Module Status table.
Establishes a per-module code review workflow under code-reviews/ and
records the 2026-05-16 baseline review (commit 9c60592): 241 findings
across all src/ modules (6 Critical, 46 High, 100 Medium, 89 Low).
This is the clean starting point for remediation work.
