Phase 1 - SecurityOptions consolidation: - Create SecurityOptionsBase with shared IP filtering, rate limiting, failed auth, and security headers options - Create AdminSecurityOptions and GatewaySecurityOptions with API-specific extensions (ApiAuth for Admin, VirtualKey for Gateway) - Shared configuration loader with environment variable parsing Phase 2 - SecurityHeadersMiddleware consolidation: - Create generic SecurityHeadersMiddleware in shared library - Admin/Gateway middleware files now delegate to shared implementation Phase 3 - SecurityMiddleware base class: - Create SecurityMiddlewareBase with template method pattern - Admin/Gateway inherit base and add API-specific behavior - Gateway adds event monitoring via OnSecurityViolationAsync override Phase 4 - SignalRNotificationServiceBase: - Create generic base class with optional resilience policies - Provides SendToGroupAsync, SendToAllAsync helper methods - Refactor SystemNotificationService and VideoGenerationNotificationService Benefits: - ~750 lines of duplicated code eliminated - Single source of truth for security configuration - Consistent error handling patterns across services - Optional resilience policies for SignalR notifications --- .../Extensions/SecurityOptionsExtensions.cs | 85 +----- .../Extensions/ServiceCollectionExtensions.cs | 4 +- .../Middleware/SecurityHeadersMiddleware.cs | 93 +------ .../Middleware/SecurityMiddleware.cs | 55 ++-- .../Services/SecurityService.cs | 6 +- .../Extensions/SecurityOptionsExtensions.cs | 111 +------- .../Extensions/ServiceCollectionExtensions.cs | 8 +- .../Middleware/SecurityHeadersMiddleware.cs | 101 +------ .../Middleware/SecurityMiddleware.cs | 96 +++---- .../Options/SecurityOptions.cs | 246 ------------------ .../Services/SecurityService.Core.cs | 6 +- .../Services/SystemNotificationService.cs | 133 ++++------ .../VideoGenerationNotificationService.cs | 160 +++++------- Shared/ConduitLLM.Core/ConduitLLM.Core.csproj | 1 + .../SignalRNotificationServiceBase.cs | 237 +++++++++++++++++ .../ConduitLLM.Security.csproj | 5 + .../Middleware/SecurityHeadersMiddleware.cs | 125 +++++++++ .../Middleware/SecurityMiddlewareBase.cs | 121 +++++++++ .../Models/SecurityCheckResult.cs | 65 +++++ .../Options/AdminSecurityOptions.cs | 62 +++++ .../Options/GatewaySecurityOptions.cs | 132 ++++++++++ .../Options/SecurityOptionsBase.cs | 67 ++--- .../Options/SecurityOptionsExtensions.cs | 232 +++++++++++++++++ .../Admin/Services/SecurityServiceTests.cs | 15 +- 24 files changed, 1247 insertions(+), 919 deletions(-) delete mode 100644 Services/ConduitLLM.Gateway/Options/SecurityOptions.cs create mode 100644 Shared/ConduitLLM.Core/Services/SignalRNotificationServiceBase.cs create mode 100644 Shared/ConduitLLM.Security/Middleware/SecurityHeadersMiddleware.cs create mode 100644 Shared/ConduitLLM.Security/Middleware/SecurityMiddlewareBase.cs create mode 100644 Shared/ConduitLLM.Security/Models/SecurityCheckResult.cs create mode 100644 Shared/ConduitLLM.Security/Options/AdminSecurityOptions.cs create mode 100644 Shared/ConduitLLM.Security/Options/GatewaySecurityOptions.cs rename Services/ConduitLLM.Admin/Options/SecurityOptions.cs => Shared/ConduitLLM.Security/Options/SecurityOptionsBase.cs (73%) create mode 100644 Shared/ConduitLLM.Security/Options/SecurityOptionsExtensions.cs diff --git a/Services/ConduitLLM.Admin/Extensions/SecurityOptionsExtensions.cs b/Services/ConduitLLM.Admin/Extensions/SecurityOptionsExtensions.cs index 34dea2bf..0be959a6 100644 --- a/Services/ConduitLLM.Admin/Extensions/SecurityOptionsExtensions.cs +++ b/Services/ConduitLLM.Admin/Extensions/SecurityOptionsExtensions.cs @@ -1,84 +1,25 @@ -using ConduitLLM.Admin.Options; +// Re-export the shared security options extension methods for Admin API +// This file is a facade that delegates to the shared ConduitLLM.Security library +using ConduitLLM.Security.Options; namespace ConduitLLM.Admin.Extensions { /// - /// Extension methods for configuring security options + /// Extension methods for configuring Admin security options. + /// Delegates to the shared ConduitLLM.Security.Options.SecurityOptionsExtensions. /// - public static class SecurityOptionsExtensions + public static class AdminSecurityOptionsExtensions { /// - /// Configures security options from environment variables + /// Configures Admin security options from environment variables. + /// This is a facade method that delegates to the shared implementation. /// - public static IServiceCollection ConfigureAdminSecurityOptions(this IServiceCollection services, IConfiguration configuration) + public static IServiceCollection ConfigureAdminSecurityOptions( + this IServiceCollection services, + IConfiguration configuration) { - services.Configure(options => - { - // IP Filtering - options.IpFiltering.Enabled = configuration.GetValue("CONDUIT_ADMIN_IP_FILTERING_ENABLED", false); - options.IpFiltering.Mode = configuration["CONDUIT_ADMIN_IP_FILTER_MODE"] ??

Subject: [PATCH 030/202] feat: Implement pagination for repositories and
 deprecate old methods

- Added GetPaginatedAsync methods to ModelProviderMappingRepository, NotificationRepository, ProviderKeyCredentialRepository, ProviderRepository, RequestLogRepository, VirtualKeyGroupRepository, and VirtualKeyRepository for efficient data retrieval.
- Deprecated GetAllAsync methods in the above repositories with warnings to use the new paginated methods.
- Introduced GetByProviderPaginatedAsync and GetByModelPaginatedAsync methods for specific filtering and pagination.
- Updated tests to reflect changes in repository methods and ensure correct functionality.
- Modified frontend components to handle paginated data responses.
- Added VirtualKeyCountsDto for tracking virtual key counts by status.

Subject: [PATCH 031/202] refactor: implement generic RepositoryBase to
 eliminate CRUD boilerplate

Introduce RepositoryBase abstract class that provides common
CRUD operations, reducing ~3000 lines of duplicated code across 18 repositories.

Key changes:
- Add IEntity, IAuditableEntity, ISoftDeletable marker interfaces
- Create IRepositoryBase interface for standard operations
- Implement RepositoryBase with GetByIdAsync, CreateAsync, UpdateAsync,
  DeleteAsync, GetPaginatedAsync, ExistsAsync, CountAsync
- Migrate 18 repositories to use RepositoryBase (Tiers 1-3)
- Fix RefundService to properly persist group balance updates
- Fix test mock callbacks to match method parameter counts

Function repositories (Tier 4) not migrated due to circular dependency
constraint and complex domain logic (transactions, leasing, auto-primary).

Subject: [PATCH 032/202] refactor: improve repository patterns and add
 database-level media search

- Add SearchByStorageKeyPatternAsync to IMediaRecordRepository for efficient
  database-level filtering using PostgreSQL ILIKE, replacing inefficient
  client-side filtering that loaded all records into memory

- Refactor FunctionExecutionRepository to inherit from new FunctionRepositoryBase,
  aligning with RepositoryBase pattern while avoiding circular dependencies

- Add IFunctionEntity interface to ConduitLLM.Functions to enable generic
  repository patterns without circular project references

- Add standard CRUD operations (GetPaginatedAsync, ExistsAsync, CountAsync,
  DeleteAsync) to IFunctionExecutionRepository interface

- Update FunctionExecution entity to implement IFunctionEntity

Subject: [PATCH 033/202] refactor: consolidate LoggingSanitizer
 implementations

- Convert Core/Extensions/LoggingSanitizer to facade delegating to
  Configuration/Utilities/LoggingSanitizer (canonical implementation)
- Mark LogSanitizer.cs as obsolete with migration guidance
- Eliminate duplicate sanitization logic across projects
- Maintain backward compatibility via facade pattern

Subject: [PATCH 034/202] feat: enable distributed cache statistics in
 AddCacheManager

- AddCacheManager(IConfiguration) now auto-detects Redis configuration
- When Redis is available, uses HybridCacheStatisticsCollector for
  statistics that survive service restarts
- Falls back to in-memory CacheStatisticsCollector when Redis unavailable
- Aligns behavior with AddCacheInfrastructure for consistency

Subject: [PATCH 036/202] fix: improve null handling in MiniMax JSON
 deserialization

- Replace null-forgiving operator with proper null coalescing throws
- JsonSerializer.Deserialize can return null, now throws clear exception
- Change catch clause to JsonException for more specific error handling
- Provides clearer error messages when API returns unexpected null

Subject: [PATCH 038/202] refactor: consolidate provider authentication
 verification in base class

BaseLLMClient.cs:
- VerifyAuthenticationAsync now makes actual HTTP request to verify auth
- Uses GetHealthCheckUrl() to determine verification endpoint
- Comprehensive error handling (401, 403, network, timeout)
- Default endpoint changed to /models (OpenAI-compatible standard)

GroqClient.Authentication.cs:
- Simplified to only override GetHealthCheckUrl()
- Removes ~50 lines of duplicate authentication code
- Now uses base class implementation for verification

Providers following standard pattern (Bearer token + /models) can now
inherit authentication verification without any overrides.

Subject: [PATCH 039/202] refactor: consolidate HTTP client timeout
 configuration across providers

Add ProviderHttpClientOptions class with centralized timeout settings for
different operation types. Add timeout constants to BaseLLMClient and
update MiniMax clients to use consistent values instead of hardcoded ones.

- Mark sync ClearCache() as obsolete with guidance to use async version
- Convert InMemoryMediaStorageService.CompleteMultipartUploadAsync to proper async/await

Subject: [PATCH 042/202] fix: enforce IHttpClientFactory usage to prevent
 socket exhaustion

- Convert obsolete methods in ContentParts.cs and ImageUtility.cs to throw
  NotSupportedException instead of creating new HttpClient instances
- Replace fallback new HttpClient() with InvalidOperationException in:
  - BaseLLMClient.CreateHttpClient()
  - BaseLLMClient.CreateAuthenticationVerificationClient()
  - ExaClient.CreateHttpClient()
  - TavilyClient.CreateHttpClient()
  - MiniMaxClient.CreateVideoHttpClient()

This enforces proper dependency injection configuration and prevents
silent socket exhaustion under high load. Callers must now use the
overloads that accept HttpClient from IHttpClientFactory.

Subject: [PATCH 043/202] refactor: centralize cache key constants to prevent
 collisions and duplication

Create CacheKeys static class with nested classes for each domain (VirtualKey,
ModelCost, GlobalSetting, Provider, IpFilter, Ephemeral, Embedding, ProviderError,
ModelMapping, MediaProgress, Stats, etc.) to provide consistent cache key patterns
across all services. This eliminates ~40 scattered private const declarations and
reduces risk of key collisions in distributed cache environments.

Subject: [PATCH 044/202] refactor: migrate from deprecated LogSanitizer to
 LoggingSanitizer

Replace all usages of the obsolete LogSanitizer.SanitizeObject() with
LoggingSanitizer.S() across repository classes. This eliminates 194
build warnings and uses the recommended sanitization API.

Subject: [PATCH 045/202] refactor: migrate from deprecated GetAllAsync to
 paginated repository methods

- Add RepositoryPaginationExtensions helper for iterating through paginated results
- Update 19 production files to use GetPaginatedAsync via helper extension
- Update 9 test files with correct mock setups for paginated methods
- Resolves 73 CS0618 obsolete warnings

Subject: [PATCH 046/202] refactor: consolidate HTTP helpers by renaming
 Providers.HttpClientHelper to ProviderHttpHelper

Eliminated confusion from having two classes with the same name in different namespaces.
The Providers helper was mostly delegating to Core.Utilities.HttpClientHelper anyway.

- Rename HttpClientHelper to ProviderHttpHelper in Providers.Helpers namespace
- Remove delegation methods (SendJsonRequestAsync, SendStreamingRequestAsync) that just
  forwarded calls to Core.Utilities.HttpClientHelper
- Remove duplicate DefaultJsonOptions field
- Retain unique provider-specific methods: SendFormRequestAsync, FormatQueryParameters,
  AppendQueryParameters, CreateMultipartHeaders, CreateMultipartContent

Subject: [PATCH 047/202] fix: enable previously skipped Redis webhook metrics
 test

- Remove Skip attribute from GetStatisticsAsync_AggregatesMultipleUrls test
- Mock both IServer.Keys() overloads (4-param and 6-param) to ensure
  the service call is intercepted regardless of which overload is used
- Fix DateTime timestamp format from ISO 8601 ("O") to simple sortable
  format ("yyyy-MM-dd HH:mm:ss") to avoid DateTime.TryParse ambiguity
- Use specific key matchers for HashGetAllAsync mock setup

This increases Redis test coverage from 98 passed + 1 skipped to
99 passed + 0 skipped.

Subject: [PATCH 048/202] refactor: reduce provider code duplication with
 centralized registries and strategies

Implement authentication strategy pattern (Bearer, Token, api-key header) and
centralized ProviderConfigurationRegistry to eliminate duplicated Constants
classes across providers. Add ClientCreatorRegistry to replace factory switch
statement. Create streaming chunk converters for OpenAI, Groq, and MiniMax.

Subject: [PATCH 049/202] feat: add query monitoring and deprecate unbounded
 GetAllAsync methods

Add infrastructure to prevent accidental full table scans:

- Add QueryMonitoringInterceptor to detect slow queries and large result sets
- Add GetAllUnboundedAsync() as explicit opt-in for legitimate batch operations
- Deprecate GetAllAsync() on repository interfaces with migration guidance
- Add GetPaginatedAsync() to function repositories for bounded queries
- Update services and controllers to use GetAllUnboundedAsync() for small tables
- Document unbounded query prevention policy in repository-and-data-access.md

This enforces query result size limits across all repositories to protect
production systems from memory pressure and database strain.

+## Unbounded Query Prevention
+
+To prevent accidental full table scans and protect production systems, ConduitLLM enforces query result size limits across all repositories.
+
+### The Problem
+
+Unbounded queries like `GetAllAsync()` can cause severe performance issues:
+- **Memory pressure**: Loading millions of records into memory
+- **Database strain**: Full table scans blocking other queries
+- **Response timeouts**: Requests timing out under load
+- **Cascading failures**: One bad query affecting entire system
+
+### Solution: Query Monitoring and Explicit Opt-In
+
+#### 1. Query Monitoring Interceptor
+
+All database queries are monitored via `QueryMonitoringInterceptor`:
+
+```csharp
+// Configuration (appsettings.json or environment variables)
+{
+  "QueryMonitoring": {
+    "Enabled": true,
+    "SlowQueryThresholdMs": 5000,      // Log warning for queries > 5 seconds
+    "LargeResultSetThreshold": 1000,   // Log warning for result sets > 1000 rows
+    "LogFullCommand": false            // Set true to include SQL in logs (dev only)
+  }
+}
+```
+
+#### 2. Deprecated GetAllAsync Methods
+
+The `GetAllAsync()` method is deprecated on all repository interfaces:
+
+```csharp
+// ❌ DEPRECATED - Triggers compile-time warning
+var allItems = await repository.GetAllAsync();
+
+// ✅ PREFERRED - Bounded pagination
+var (items, totalCount) = await repository.GetPaginatedAsync(page: 1, pageSize: 50);
+
+// ✅ EXPLICIT OPT-IN - For legitimate batch operations (cache warming, exports)
+var allItems = await repository.GetAllUnboundedAsync();
+```
+
+#### 3. Legitimate Unbounded Queries
+
+Use `GetAllUnboundedAsync()` only for:
+- **Cache warming**: Loading small reference tables at startup
+- **Data exports**: Admin-initiated bulk exports with user awareness
+- **Migrations**: One-time data migration scripts
+- **Small reference tables**: Tables guaranteed to have <100 records
+
+```csharp
+// Safe - Small reference table, used for cache warming
+var settings = await _globalSettingRepository.GetAllUnboundedAsync();
+var ipFilters = await _ipFilterRepository.GetAllUnboundedAsync();
+
+// UNSAFE - High-risk tables, always use pagination
+// var logs = await _requestLogRepository.GetAllUnboundedAsync(); // DON'T DO THIS
+var (logs, total) = await _requestLogRepository.GetPaginatedAsync(1, 100);
+```
+
+### Table Risk Classification
+
+| Risk Level | Tables | Policy |
+|------------|--------|--------|
+| **Critical** | RequestLog, VirtualKeySpendHistory, MediaRecord, AsyncTask | Pagination required, no unbounded access |
+| **High** | VirtualKey, Notification, BatchOperationHistory | Pagination strongly recommended |
+| **Low** | GlobalSetting, IpFilter, Provider, ModelSeries, ModelAuthor | Unbounded allowed (small tables) |
+
+### Best Practices
+
+1. **Default to pagination**: Always use `GetPaginatedAsync()` unless you have a specific need
+2. **Set reasonable page sizes**: Max 100 items per page, default 20
+3. **Implement cursor-based pagination**: For real-time data streams
+4. **Add WHERE clauses**: Filter at the database level, not in memory
+5. **Monitor query performance**: Check logs for `SlowQueryThresholdMs` warnings
+
+### Example: Migrating from GetAllAsync
+
+**Before (anti-pattern):**
+```csharp
+public async Task> GetAllItemsAsync()
+{
+    var items = await _repository.GetAllAsync(); // Loads ALL records
+    return items.Select(MapToDto);
+}
+```
+
+**After (pagination):**
+```csharp
+public async Task> GetItemsAsync(int page, int pageSize)
+{
+    var (items, totalCount) = await _repository.GetPaginatedAsync(page, pageSize);
+    return new PagedResult
+    {
+        Items = items.Select(MapToDto).ToList(),
+        TotalCount = totalCount,
+        Page = page,
+        PageSize = pageSize
+    };
+}
+```

 ## Testing
 
 Repositories make it easier to write tests that don't depend on a database:

From d7afa04bd038c3a6eecf758f2175dff699aee2fa Mon Sep 17 00:00:00 2001
From: Nick Nassiri 
Date: Thu, 29 Jan 2026 14:27:21 -0800
Subject: [PATCH 050/202] refactor: extract Gateway service registrations into
 focused extension methods

Extract 10 domain-specific extension methods from the 730+ line ConfigureCoreServices
method to improve DI graph comprehension and maintainability:

- WebhookServicesExtensions: webhook delivery, metrics, circuit breakers
- HttpClientServicesExtensions: image/video download, function provider clients
- ObservabilityExtensions: OpenTelemetry metrics/tracing, query monitoring
- SignalRServicesExtensions: reliability services (acknowledgment, queue, monitor)
- BillingServicesExtensions: cost calculation, billing/pricing audit
- DatabaseServicesExtensions: connection management, DbContext factory
- BatchOperationServicesExtensions: TaskHub, batch operations, idempotency
- AuditServicesExtensions: request log, function call audit
- MediaGenerationExtensions: video generation, metrics, orchestrators
- FunctionServicesExtensions: function repositories, execution, orchestration

Reduces ConfigureCoreServices from 843 to 192 lines (~77% reduction).

Subject: [PATCH 051/202] fix: remove legacy webpack config for Next.js 16
 Turbopack compatibility

Next.js 16 uses Turbopack by default and fails when it detects a webpack
config without a corresponding turbopack config. The removed webpack
configuration contained legacy/debugging code that is no longer needed:
- CommonJS externals for WebSocket libraries (handled automatically)
- Malformed React DevTools DefinePlugin
- Debug settings disabling minification in production
- Misplaced watchOptions in production code path

Subject: [PATCH 057/202] fix: use ContractlessStandardResolver for SignalR
 MessagePack serialization

The StandardResolver requires [MessagePackObject] attributes on all types,
which the metrics DTOs (MetricsSnapshot, WebhookStatistics, etc.) don't have.
This caused serialization failures when broadcasting metrics via SignalR.

ContractlessStandardResolver can serialize any public properties without
requiring attributes, fixing the "not registered in resolver" errors.

Subject: [PATCH 058/202] fix: ignore TIME_WAIT connections in port conflict
 detection

TIME_WAIT is a transient TCP state where a socket is waiting for delayed
packets after closing. These connections don't actually block the port
and will be released automatically (typically within 30-240 seconds).

The port check now only considers active states (Listen, Established,
SynSent, SynReceived) as true conflicts, preventing false positives
that would block start-dev.ps1 from running.

Subject: [PATCH 059/202] refactor: migrate 30 Admin controllers to
 AdminControllerBase for centralized error handling

Replace ~150 manual try/catch blocks across 30 Admin API controllers with
AdminControllerBase's ExecuteAsync/ExecuteWithNotFoundAsync methods, providing
consistent error responses via ExceptionToResponseMapper. Added convenience
constructor to AdminControllerBase for controllers without IPublishEndpoint.
Updated all corresponding unit and integration tests for the new ErrorResponseDto
format.

Subject: [PATCH 060/202] refactor: consolidate virtual key validation and
 utility code into shared projects

Move VirtualKeyUtilities to Shared/ConduitLLM.Configuration and
VirtualKeyValidationHelper to Shared/ConduitLLM.Core so both Gateway
and Admin services can reuse them. Remove ~120 lines of duplicated
IsModelAllowed, HashKey, GenerateSecureKey, and inline validation logic
from ApiVirtualKeyService and AdminVirtualKeyService.

Subject: [PATCH 061/202] refactor: remove redundant ModelState checks and
 replace Redis KEYS with SCAN
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove 28 dead ModelState.IsValid checks across 13 controllers — all already
have [ApiController] which handles validation automatically via action filter.
Remove one unit test that only tested the now-removed manual check.

Replace all 4 Redis KEYS commands in SignalRConnectionMonitor with server.Keys()
(SCAN-based) to avoid blocking the Redis server during full keyspace scans.
Fix race condition in CleanupEmptyGroupsAsync by replacing List+lock with
ConcurrentBag.

Subject: [PATCH 062/202] refactor: remove sync-over-async wrappers from
 SignalRConnectionMonitor

Remove 6 deprecated synchronous methods that used .GetAwaiter().GetResult()
to wrap async implementations, risking thread pool starvation and deadlocks.

Replace sync signatures in ISignalRConnectionMonitor interface with async
equivalents. Migrate all callers (SignalRHealthController,
SignalROpenTelemetryService) to use the async methods directly.

Subject: [PATCH 063/202] fix: replace async void with fire-and-forget Task in
 Redis Pub/Sub handlers

Convert OnKeyInvalidated and OnBatchInvalidated in RedisVirtualKeyCache
from async void to synchronous methods that delegate to async Task methods
via discard (_ = MethodAsync()). This matches the pattern already used in
RedisModelCostCache and prevents potential process crashes from unobserved
exceptions in async void methods.

Subject: [PATCH 064/202] fix: remove sync-over-async blocking in
 TiktokenCounter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make EstimateTokenCountAsync methods truly async by calling the existing
GetEncodingForModelAsync instead of the synchronous GetEncodingForModel
which used .GetAwaiter().GetResult() to block on the capability service.

Delete the synchronous GetEncodingForModel method entirely — it was a
duplicate of GetEncodingForModelAsync with a blocking call that risked
thread pool starvation and deadlocks on this hot path.

Subject: [PATCH 065/202] fix: replace blocking Redis calls in cache
 constructors with fire-and-forget

Convert .GetAwaiter().GetResult() stats initialization in RedisIpFilterCache,
RedisGlobalSettingCache, and RedisProviderCredentialCache constructors to
non-blocking fire-and-forget with ContinueWith error logging. This matches
the pattern already used in RedisModelCostCache and prevents constructor
blocking during DI resolution.

Subject: [PATCH 066/202] refactor: centralize entity-to-DTO mapping into
 shared extension methods

Move 7 private MapToDto methods from controllers/services into a single
EntityMappingExtensions class with ToDto() extension methods. Also removes
duplicate ModelProviderMapping ToDto/ToEntity from RepositoryExtensions
that duplicated ProviderMappingExtensions.

Subject: [PATCH 067/202] refactor: reduce duplication and fix async patterns
 across solution

- Delete dead IModelCapabilityDetector code (unused since routing removal)
- Add GatewayControllerBase with OpenAI-compatible error handling, migrate
  EmbeddingsController and ModelsController to use it
- Extract shared SignalR configuration into SignalRConfigurationExtensions,
  replacing ~100 lines of duplication between Gateway and Admin
- Centralize Redis connection string resolution into
  RedisUrlParser.ResolveConnectionString(), replacing 5 duplicate blocks
- Add IAsyncDisposable to RedisCacheStatisticsCollector and
  BatchSpendUpdateService to avoid sync-over-async in Dispose()
- Remove sync FunctionClientFactory.GetClient() wrapper, migrate callers
  to GetClientAsync()
- Remove obsolete ModelCostService.ClearCache() with dangerous
  Task.Run().Wait() pattern

Subject: [PATCH 068/202] refactor: replace in-memory analytics grouping with
 database-level aggregation

Analytics methods previously loaded all request log rows into memory via
GetByDateRangeAsync() then grouped/filtered in C#, potentially processing
millions of rows. Now uses SQL GROUP BY via 7 new repository methods
(GetCostsByDateAsync, GetAggregatedByModelAsync, GetSummaryAsync, etc.)
so only small aggregate result sets are returned.

Subject: [PATCH 069/202] refactor: fix bugs, reduce duplication, and
 standardize test assertions

- Fix resource leaks in ImageTokenCalculator (undisposed HttpRequestMessage/HttpResponseMessage)
- Centralize Redis server resolution with RedisExtensions.GetPrimaryServer() replacing 16 crash-prone GetEndPoints().First() calls
- Consolidate 3 duplicate HTTP retry policies into shared HttpRetryPolicies class, fix thread-unsafe new Random()
- Reduce S3 config binding duplication with ApplyConfigOrEnvVar() helper
- Extract AddFunctionProviderHttpClient() eliminating duplicate Exa/Tavily HttpClient registrations
- Replace 14 sync-over-async .Result calls with proper await in AnalyticsService and RedisVirtualKeyCache
- Decompose 119-line ProcessGroupAsync in MediaCleanupService into 3 focused methods
- Remove dead CancellationTokenSource in MediaCleanupService.DeleteFromStorageAsync
- Add 26 tests for previously untested RefundService, AdminGlobalSettingService, AdminNotificationService
- Standardize all 448 Assert.IsType/IsAssignableFrom calls to FluentAssertions across 59 test files

Subject: [PATCH 070/202] refactor: migrate Gateway controllers to
 GatewayControllerBase and consolidate cache invalidation consumers

Migrate TasksController, ProviderModelsController, and BatchOperationsController to use
GatewayControllerBase for consistent OpenAI-compatible error responses. Create
CacheInvalidationConsumerBase to eliminate duplicated try/catch/log/rethrow
scaffolding across 5 simple cache invalidation handlers.

From 970335264e9547e8a2051de6904930284217bf88 Mon Sep 17 00:00:00 2001
From: Nick Nassiri 
Date: Tue, 10 Feb 2026 16:37:23 -0800
Subject: [PATCH 071/202] refactor: unify entity interfaces, reduce repository
 boilerplate, and fix resource leaks

- Unify IFunctionEntity into IIdentifiableEntity, delete FunctionRepositoryBase
- Add RepositoryBase.ExecuteAsync with optional operationName for centralized error logging
- Simplify try-catch boilerplate across 11 repositories (70+ methods)
- Fix HttpResponseMessage leaks in OpenAI, Replicate, MiniMax, and streaming clients
- Consolidate Cerebras/SambaNova error handling into shared ExceptionHandler
- Extract shared ValidationResult class, rename cache-specific to CacheValidationResult
- Extract duplicate RequestLog mapping into MapToRequestLog helper
- Delete dead code: DateTimeExtensions, LoggerMockExtensions
- Fix connection string parsing bug (Split with limit parameter)

From 4e05925b0f7a53de4268d73fb5e981249bf4a27f Mon Sep 17 00:00:00 2001
From: Nick Nassiri 
Date: Thu, 26 Feb 2026 01:00:19 -0800
Subject: [PATCH 072/202] chore: update NuGet and npm dependencies to latest
 compatible versions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update all .NET packages to latest patch/minor versions: Microsoft.* 10.0.1→10.0.3,
OpenTelemetry 1.14→1.15, AWSSDK.S3 4.0.16→4.0.18, StackExchange.Redis 2.10→2.11,
Scalar.AspNetCore 2.11→2.12, coverlet 6→8, bunit 2.4→2.5, BenchmarkDotNet 0.14→0.15,
and others. Promote OpenTelemetry.Instrumentation.SqlClient from 1.10-beta to 1.15
stable and remove obsolete SetDbStatementForText option (now always enabled).

Update npm packages in WebAdmin (@clerk, @mantine, @tanstack, typescript-eslint, etc.)
and SDKs (@types/node, @typescript-eslint, prettier, eslint) to latest semver-compatible
versions.

Skip MassTransit 8→9 (commercial licensing change) and ApplicationInsights 2→3
(architectural rewrite) as intentional holds.

From 7153c387cf296ec5cb2e5fd339a3252c6cabbf90 Mon Sep 17 00:00:00 2001
From: Nick Nassiri 
Date: Mon, 9 Mar 2026 16:09:02 -0700
Subject: [PATCH 073/202] chore: update NuGet packages to latest release
 versions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MassTransit 8.5.7→9.0.1, ApplicationInsights 2.23.0→3.0.0,
Scalar 2.12.47→2.13.2, Polly 8.6.5→8.6.6, bunit 2.5.3→2.6.2,
AWS SDK patches, and OpenTelemetry.Instrumentation.SqlClient 1.15.1.
Added System.Diagnostics.PerformanceCounter as explicit dependency
after ApplicationInsights 3.0 removed the transitive reference.

Subject: [PATCH 074/202] fix: downgrade MassTransit from 9.0.1 to 8.5.7 to fix
 license requirement

MassTransit v9 introduced a mandatory commercial license that prevented
the admin container from starting. Downgrade to v8.5.7 (Apache 2.0)
which is the same version already used by ConduitLLM.Functions.

Subject: [PATCH 075/202] remove: delete security dashboard page and dead code
 (no backend exists)

The security dashboard called non-existent backend endpoints (/api/security/events,
/api/security/threats, /api/security/compliance), causing the page to fail on load.
Removed the page, SDK security service/models, and navigation entries. Moved
PagedResult to common-types since other services depend on it.

Subject: [PATCH 135/202] feat: thread cached token data through request
 logging, metrics, and aggregations

Cached token counts (CachedInputTokens, CachedWriteTokens) from prompt
caching were already tracked in Usage and used for cost calculation, but
were discarded at the observability layer. This adds nullable cached token
fields to RequestLog/LogRequestDto, emits cached_input/cached_write label
values to Prometheus counters, and includes cached token SUMs in all
aggregation queries so caching efficacy is measurable end-to-end.

Subject: [PATCH 136/202] feat: add prompt caching observability with Grafana
 dashboard and Prometheus metrics

Add end-to-end prompt caching monitoring: new Prometheus metrics for
request-level cache hit/miss tracking, cost savings calculation, and
injection health; a dedicated Grafana dashboard with 11 panels across
4 rows (cost savings overview, token breakdown, cost analysis, and
operational health); and cache savings computation in CostCalculationService.

Subject: [PATCH 137/202] feat: add prompt caching provider pipeline with
 cache_control passthrough

Wire PromptCachingLLMClient decorator into DatabaseAwareLLMClientFactory,
add ContentHelper.ShouldPreserveAsArray to prevent cache_control directives
from being stripped during OpenAI-compatible message mapping, extend
GlobalSettingsCacheService with setting existence checks, and add Admin API
controller/DTOs/config model/injection service with full test coverage.

Subject: [PATCH 140/202] fix: migrate WebAdmin to Turbopack with standalone
 Docker output

- Add Turbopack resolveAlias for monorepo SDK packages to fix Next.js 16
  build failures (CI broken since Jan 2026)
- Enable standalone output for optimized Docker deployments, eliminating
  need for node_modules and SDK symlinks in production image
- Remove productionBrowserSourceMaps (security: exposes source in prod)
- Remove --webpack flag from dev script for consistent Turbopack usage
- Fix npm-publish CI job referencing non-existent Core SDK (was Gateway)
- Set cancel-in-progress: true to avoid wasting CI on superseded commits

Subject: [PATCH 141/202] refactor: remove dead code and consolidate
 SecurityService into shared base

Remove CacheManagementService (never-registered, returned 501), HealthMonitoringTestController
(could cause real resource exhaustion), stale removed/migrated comments, and empty no-op methods.

Extract shared SecurityServiceBase in ConduitLLM.Security with common IP banning, rate limiting,
IP filtering, and failed auth tracking. Admin and Gateway SecurityService now inherit from it,
eliminating ~500 lines of duplicated code. Admin no longer duplicates IpAddressHelper logic.

Subject: [PATCH 142/202] refactor: remove unused SpendNotificationService,
 extract shared controller logic, consolidate media controllers

- Delete unused in-memory SpendNotificationService (distributed version is active)
- Extract IsMutationRequest(), LogExceptionWithBodyAsync(), and Logger property
  from AdminControllerBase and GatewayControllerBase into EventPublishingControllerBase
- Merge MediaCleanupController into MediaController (backward-compatible routes)
- Extract MediaRetentionController inline DTOs to DTOs/MediaRetentionDtos.cs

Subject: [PATCH 143/202] refactor: extract TaskSubscriptionHub base, migrate
 ImageGenerationNotificationService to base class

- Create TaskSubscriptionHub with shared subscribe/unsubscribe logic
  for task-based media generation hubs (ownership validation, group management)
- ImageGenerationHub and VideoGenerationHub now inherit from it (~5 lines each)
- Migrate ImageGenerationNotificationService to use SignalRNotificationServiceBase
  (consistent with VideoGenerationNotificationService pattern)
- Fix bug: VideoGenerationNotificationService used hardcoded "video-{taskId}" group
  name instead of SignalRConstants.Groups.VideoTask(taskId) in cancel method
- Add missing VideoGenerationCancelled constant to SignalRConstants

Subject: [PATCH 144/202] refactor: remove dead SignalRMetricsService, fix
 duplicate BusinessMetricsService registration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Delete unused SignalRMetricsService (305 lines) — DistributedSignalRMetricsService
  is the only registered implementation
- Remove duplicate BusinessMetricsService registration from Program.SignalR.cs
  (canonical registration is in Program.Monitoring.cs with leader election)
- Remove non-leader-elected BusinessMetricsService registration from
  ObservabilityExtensions (would cause duplicate metrics in scaled deployments)

Subject: [PATCH 145/202] refactor: split ModelController and
 UsageTrackingMiddleware into partial classes

Split Admin ModelController (989 lines) into 3 partial class files:
- ModelController.cs: core CRUD operations
- ModelController.Identifiers.cs: identifier endpoints
- ModelController.ProviderMappings.cs: provider mapping endpoints

Split Gateway UsageTrackingMiddleware (1,211 lines) into 4 partial class files:
- UsageTrackingMiddleware.cs: pipeline entry, routing, response interception
- UsageTrackingMiddleware.Streaming.cs: streaming usage tracking
- UsageTrackingMiddleware.MediaProcessing.cs: function/image/video processing
- UsageTrackingMiddleware.BillingAndMetrics.cs: request logging, billing, caching

Subject: [PATCH 150/202] refactor: consolidate error handling, notification
 services, and Admin Program structure

- Move ExtractEnhancedErrorMessage from OpenAICompatibleClient to BaseLLMClient,
  simplifying Groq/OpenRouter overrides by removing redundant fallback checks
- Delete dead FetchStreamChunksAsync (zero callers) from streaming code
- Rename ModelMappingCacheInvalidationConsumer to Handler per naming convention
- Migrate VirtualKeyManagement, UsageAnalytics, BatchOperation notification
  services to SignalRNotificationServiceBase, removing manual try-catch boilerplate
- Split Admin Program.cs (347 lines) into partial classes matching Gateway pattern

  with ExecuteAsync() for consistent OpenAI-compatible error responses
- Add NotSupportedException mapping and OpenAIError() helper to shared base classes
- Remove ~100 Console.WriteLine calls from startup code across Gateway, Admin, and Shared
- Convert Polly webhook callbacks to structured ILogger via IServiceProvider
- Extract duplicated GetHubContext into shared SignalRHubContextResolver utility
- Update 13 test files to assert OpenAIErrorResponse instead of ErrorResponseDto/ProblemDetails

From b9d1f8d2648f5d2e99df0914215ecf91ba12a403 Mon Sep 17 00:00:00 2001

Subject: [PATCH 152/202] refactor: migrate WebAdmin business logic into SDK
 packages for cross-project reuse

Move shared formatting, validation, cost display, error messaging, and model
pattern matching logic from WebAdmin into the Common and Admin SDK packages.
WebAdmin files are replaced with thin re-export shims so all existing imports
continue to work unchanged.

New SDK modules:
- @knn_labs/conduit-common: formatting/, validation/, errors/error-messages
- @knn_labs/conduit-admin-client: utils/costFormatters

Subject: [PATCH 153/202] refactor: extract middleware base classes, centralize
 WebAdmin notifications, remove dead CacheConfigurationService

Backend:
- Extract EphemeralKeyCleanupMiddlewareBase for shared ephemeral key cleanup logic
- Extract ExceptionHandlingMiddlewareBase for shared exception handling (logging, mapping, headers)
- Extract ModelRepository.ApplyDetailIncludes() to eliminate 4 duplicate include chains
- Remove dead CacheConfigurationService (~1,500 lines) - fully implemented but never consumed
- Add migration to drop unused CacheConfigurations and CacheConfigurationAudits tables

WebAdmin:
- Create centralized notify utility (success/error/warning/info/loading/updateLoading)
- Create useAdminMutation factory hook for standardized React Query mutations
- Create useFormModal and useConfirmModal hooks for modal form boilerplate
- Migrate ~70 files from raw notifications.show() to notify utility
- Migrate 12 modals to useFormModal/useConfirmModal hooks
- Migrate 7 mutation hooks to useAdminMutation factory
