perf: close Theme 6 — 11 allocation / N+1 / lock-contention findings
Well-localised perf fixes across 8 modules.
Lock decoupling / SQL streaming:
- AuditLog-005: SqliteAuditWriter gains dedicated read-only _readConnection
(+ _readLock) backed by WAL journal mode. GetBacklogStatsAsync,
ReadPendingAsync, ReadPendingSinceAsync, ReadForwardedAsync no longer
contend with the hot-path INSERT lock — backlog probes on a 30s timer
can't stall the writer under multi-hundred-K Pending backlog.
- SEL-022: dropped Cache=Shared from SiteEventLogger's default connection
string (single-connection logger; mode was dormant config).
Memory / streaming:
- CLI-019: bundle export streams base64 in 1 MB-aligned chunks via
Convert.TryFromBase64Chars straight into the FileStream — no more
full-bundle byte[] allocation.
- CentralUI-031: TransportImport now stages the upload to a per-session
temp file under Path.GetTempPath() (replaces in-memory byte[] field);
page implements IDisposable to delete the temp file on reset / new
upload / dispose. Per-circuit working set drops from ~100 MB to ~80 KB.
N+1 hoisting:
- Transport-008: added ITemplateEngineRepository.GetTemplatesWithChildrenAsync
bulk method; BundleImporter.PreviewAsync calls it once instead of per-
template-name. Single query with .Include(...).AsSplitQuery().
- DM-023: BuildDeployArtifactsCommandAsync's per-site loop now references
a pre-fetched GlobalArtifactSnapshot (shared scripts, external systems,
DB connections, notification lists, SMTP) instead of re-querying per site.
- MgmtSvc-023: HandleQueryDeployments unfiltered branch uses one
GetAllInstancesAsync bulk load + Dictionary<int,int?> lookup (was a
GetInstanceByIdAsync per record).
Small allocations / per-tick rebuilds:
- InboundAPI-019: AuditWriteMiddleware gates EnableBuffering() on
RequestHasBody() so GET/HEAD/DELETE/TRACE/OPTIONS and Content-Length:0
requests skip the FileBufferingReadStream allocation.
- NotifOutbox-006: ResolveAdapters dictionary now cached on
_adaptersCache (built lazily on first sweep) + actor-lifetime
_adaptersScope; ResolveAdapters no longer rebuilds per dispatch tick.
Verify-only:
- Comm-017: Confirmed _inProgressDeployments was deleted by Comm-016 in
commit

fix(concurrency/lifetime): close Theme 5 — 10 concurrency / DI / scope findings
Concurrency hazards, DI lifetime hygiene, and one verify-only confirmation
across 8 modules. Highlights:
Concurrency:
- CentralUI-030: SandboxConsoleCapture writes routed through WriteSynchronized
locking on the captured StringWriter — intra-script Task fan-out can no
longer corrupt the per-call buffer.
- Commons-021: ExternalCallResult.Response now backed by Lazy<dynamic?>
(ExecutionAndPublication) — no more benign double-parse race.
- CD-017: DeploymentManagerRepository.DeleteDeploymentRecordAsync now takes
an expected RowVersion and seeds entry.OriginalValues so EF emits
DELETE ... WHERE Id=@id AND RowVersion=@prior; stale RowVersion now
throws DbUpdateConcurrencyException instead of silent overwrite.
- Transport-009: AuditCorrelationContext.BundleImportId backed by
AsyncLocal<Guid?> so concurrent imports get per-logical-call isolation
(was a scoped instance shared via AuditService across runs).
DI / lifetime:
- AuditLog-003: All 3 AuditLog actor handlers switched to CreateAsyncScope
+ await using — async EF disposal no longer swallowed.
- AuditLog-007: INodeIdentityProvider resolution standardised on
GetRequiredService<>() (was mixed with GetService<>()).
- AuditLog-011: AddAuditLogHealthMetricsBridge guarded by sentinel
descriptor check — calling twice no longer double-registers the hosted
service.
Shutdown / supervision:
- SiteCallAudit-002: AkkaHostedService adds a CoordinatedShutdown
cluster-leave task (drain-site-call-audit-singleton) that issues a
bounded GracefulStop(10s) so failover waits for in-flight upserts.
Registration safety:
- NS-020: AkkaHostedService now guards NotificationForwarder S&F
registration with _notificationDeliveryHandlerRegistered + throws
InvalidOperationException on double-register to make the regression loud.
VERIFY-only closures:
- NotifOutbox-005: Confirmed already closed by CD-015 fix (

fix(error-handling): close Theme 4 — 18 cancellation / fire-and-forget findings
Async cancellation hygiene, fire-and-forget observability, retry/shutdown semantics, and audit-row coverage across 9 modules. Highlights: Cancellation & lifecycle: - AuditLog-006: SqliteAuditWriter.Dispose hops to thread pool, escaping the captured SyncContext that risked sync-over-async deadlock. - AuditLog-010: SiteAuditTelemetryActor owns a private lifecycle CTS, threaded through drain paths instead of CancellationToken.None. - Comm-019: CentralCommunicationActor adds lifecycle CTS for repo calls. - Host-019: Migration StartupRetry forwards ApplicationStopping so SIGTERM during the bounded-retry window aborts cleanly. Cursor / retry / counter correctness: - AuditLog-004: SiteAuditReconciliationActor's cursor now holds at `since` when any row's idempotent insert is still being retried (per-EventId retry counter, MaxPermanentInsertAttempts=5 escape valve with LogCritical abandon). No more silent abandonment of permanently-failing rows. - ConfigDB-019: Dropped the catch-and-continue on EnsureLookaheadAsync's SPLIT loop — by class-doc construction the catch could only mask real failures and let the next iteration create permanent partition holes. - HM-017/018: HealthReportSender + CentralHealthReportLoop snapshot per-interval counters before sending, restore via new ISiteHealthCollector.AddIntervalCounters on transport failure so counts aren't silently lost. Fire-and-forget / shutdown waits: - InboundAPI-018: AuditWriteMiddleware observes faulted audit-write tasks via OnlyOnFaulted continuation (Warning log; response unchanged). - SnF-024: StoreAndForwardService.StopAsync awaits in-flight retry sweep with a bounded SweepShutdownWaitTimeout (10s). Leak / refactor: - Comm-021: SiteStreamGrpcServer.SubscribeInstance wraps Subscribe in its own try/catch so a throw doesn't leak the relay actor or _activeStreams entry. - Comm-022: VERIFIED already-closed by Comm-016's dead-code purge. - CLI-017: BundleCommands' three subcommands delegate to ExecuteCommandAsync (auth-failure exit-code contract unified). Defensive / validation: - CLI-021: CliConfig.Load wraps file-read/JSON parse so malformed config prints a warning and returns defaults instead of crashing the CLI. - Host-022: ParseLevel emits stderr one-shot warning for unrecognised MinimumLevel instead of silently coercing to Information. - ESG-019: ExternalSystemClient sets HttpClient.Timeout=Infinite so the per-call CTS is the sole timeout source (was clipped to 100s by .NET). - Security-020: New SecurityOptionsValidator (IValidateOptions) rejects empty LdapServer/LdapSearchBase with ValidateOnStart. - DM-019: Lifecycle command timeouts now emit DisableTimedOut/EnableTimedOut/ DeleteTimedOut audit entries (mirrors DeployFailed pattern). Plus reconciled stale per-module Open-findings counters that had drifted from prior sessions. 20+ new regression tests across 11 test projects; build clean; affected suites all green. README regenerated: 75 open (was 93). |

docs+code: close Theme 1 — 24 design-doc / XML-doc drift findings
Doc/XML-comment drift + small adherence fixes across 17 modules. Highlights: - Host-017: site CoordinatedShutdown ordering — SiteStreamGrpcServer gains CancelAllStreams() (refuse new streams, cancel active), wired into Program.cs site branch via ApplicationStopping. - InboundAPI-021: ParentExecutionId now travels on RouteToGet/SetAttributes symmetric with RouteToCallRequest; RouteHelper stamps from _parentExecutionId. - ClusterInfra-012: ClusterOptionsValidator now requires both seed nodes. - Comm-018: SiteCommunicationActor.HeartbeatMessage.IsActive derived from cluster leader check (was hardcoded true). - DM-020: reconciliation audit row attributes the current user, not prior deployer. - SEL-019: EventLogPurgeService early-exits on standby via active-node check. - Plus comment/XML-doc accuracy fixes across AuditLog, ConfigurationDatabase, NotificationOutbox, SiteRuntime, SiteCallAudit; doc refreshes for Component- Commons / -ManagementService / -CLI / -ExternalSystemGateway / -HealthMonitoring / -Transport / -ConfigurationDatabase; CD-023 index-name doc alignment. 11 new regression tests (RouteHelper x4, SiteStreamGrpcServer x2, ClusterOptionsValidator x1, SiteCommunicationActor x1, DeploymentService x1, EventLogPurgeService x3). Build clean (0 warnings); InboundAPI/Communication/ Host suites all green. README regenerated: 112 open (was 136). |

code-review: 2026-05-28 baseline re-review of all 23 modules at 1eb6e97
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 /
