Purpose + +`Operational` is a cross-cutting package family: a shared mechanism for issue/error capture, +in-app diagnostics, structured logging, disk-based event logging, and HTTP resilience — usable +across any application architecture (Clean, Onion, Hexagonal, monolith), safe to enable/disable at +any time without destabilizing the host application, and performance-friendly (background +processing for anything that touches disk). + +--- + +## 2. Where Operational Sits: Beside the Features Framework, Not Inside It + +**Decision: Operational is a standalone package family that sits *beside* `PowerCSharp.Features`, +not as a leaf feature inside it.** + +### Reasoning + +The Features Framework (`PowerCSharp.Features` + `Feature.Cache` + `Feature.Sanitization`) is built +for **optional, leaf capabilities** an application explicitly opts into (a cache backend, a +sanitization engine) via `AddPowerFeatures()` + `PowerFeatures::Enabled`. Its +`Feature.Sanitization.Abstractions` package is the closer precedent for Operational's shape: it is +explicitly documented as "usable standalone — no DI or feature registration required." + +Operational is different in kind from Cache or Sanitization: it's cross-cutting plumbing (error +capture, structured logging) that *other* code — potentially even Features Framework internals — +may want to call. Forcing every consumer of `IIssueManager`/`ILogger` integration to first stand up +the Features discovery engine would invert the dependency direction cross-cutting concerns are +supposed to have: diagnostics should be available to log a Features Framework startup failure, not +depend on the Features Framework having started successfully first. + +So Operational follows the **Sanitization-Abstractions shape**, not the **Cache shape**: + +- Fully usable with **zero registration** (NoOp by default) — satisfies "connect/disconnect, app + keeps working, no crashes." +- *Optionally* wires into `PowerCSharp.Features` (`OperationalFeatureModule`) for config-driven + enable/disable through the same composite flag chain as Cache and Sanitization, but never + requires it. + +--- + +## 3. Package Topology & Naming + +``` +PowerCSharp.Operational.Abstractions contracts + NoOp defaults, zero third-party deps + (netstandard2.0 + net8.0) + └─ PowerCSharp.Operational real implementation, ASP.NET Core-coupled (net8.0 only) + ├─ PowerCSharp.Operational.Sentry [future — not in this build] + └─ PowerCSharp.Operational.WinEventLog [future — not in this build] +``` + +`PowerCSharp.Operational.` (not `Feature.Operational.*`) is the naming convention for any +future provider package that isolates a third-party or platform-specific dependency — exactly like +`Feature.Cache.BitFaster` isolates `BitFaster.Caching`. Provider packages are named at the same +nesting level as `Operational`, mirroring how `PowerCSharp.Compatibility` sits beside `Core` rather +than under it. + +**Versioning:** own family, `PowerCSharpOperationalVersion`, covering `Operational.Abstractions` + +`Operational` together — the same pattern as `PowerCSharpFeatureCacheVersion` covering the whole +Cache family. Future provider packages (Sentry/WinEventLog) get their own version property when +that phase starts, mirroring the Cache/BitFaster precedent. + +### Where `IRetryPolicyProvider` lives + +`IRetryPolicyProvider` is defined in `PowerCSharp.Operational.Policies.Retry` (the core package), +not `.Abstractions`. Its members return Polly types directly (`ResiliencePipeline`, +`IAsyncPolicy`, `AsyncRetryPolicy`, `RetryPolicy`) — an interface shaped around a third-party +library's types cannot live in a zero-dependency package without leaking that dependency into every +consumer of `.Abstractions`, including ones that never touch retry logic. This is a direct +application of the dependency-isolation rule in §4, applied to the contract itself rather than only +to implementations. + +--- + +## 4. Dependency Isolation + +Following the PowerCSharp invariant already enforced for Cache and Sanitization: no third-party or +platform-specific dependency may leak into a consumer that didn't ask for it. + +- `Operational.Abstractions` — zero third-party deps (only `Microsoft.Extensions.Logging.Abstractions`). +- `Operational` — ASP.NET Core deps only (`Microsoft.AspNetCore.Http`, `Microsoft.Extensions.*`, + `Polly`) — no Sentry, no PostSharp, no third-party issue-tracking SDK. +- A future Windows Event Log implementation or third-party issue-tracking integration would live + **only** in its own provider package (`Operational.WinEventLog`, `Operational.Sentry`) — an app + that references core `Operational` alone must never pull either in transitively. + +--- + +## 5. Target Frameworks & Platform Scope + +- **This build targets ASP.NET Core / Web API only**, matching the source material's actual HTTP + coupling (`IHttpContextAccessor` used throughout `DiagnosticsService`/`DiagnosticsLogger`/ + `EventLogWriter`). No attempt is made in this phase to decouple from HTTP context. +- `Operational.Abstractions`: `netstandard2.0;net8.0` — usable from .NET Framework consumers too, + mirroring `Feature.Cache.Abstractions`/`Feature.Sanitization.Abstractions`. +- `Operational`: `net8.0` only (ASP.NET Core ecosystem, via `FrameworkReference Microsoft.AspNetCore.App`). +- A platform-agnostic version (non-web hosts — console apps, workers) is explicitly out of scope + for v1 and noted as a future phase. + +--- + +## 6. Windows Event Log — Cross-Platform Handling + +Windows Event Viewer forwarding is Windows-only by nature. Rather than guard it with +`OperatingSystem.IsWindows()` conditionals inside the core package, `PowerCSharp.Operational` ships +an `IEventViewerService`-shaped **NoOp/pluggable hook only** — no Windows Event Log code lives in +the core package at all. A real Windows implementation would become +`PowerCSharp.Operational.WinEventLog`, a separate provider package, following the same isolation +pattern as `Feature.Cache.BitFaster`. This keeps `Operational.Abstractions` genuinely cross-platform +with no conditional-compilation Windows code inside it — mirroring how `PowerCSharp.Compatibility` +is kept as its own isolated layer rather than `#if` blocks scattered through `Core`. + +--- + +## 7. Enablement Model / NoOp Pattern + +- `Operational.Abstractions` ships NoOp implementations of every contract + (`NoOpDiagnosticsService`, `NoOpIssueManager`, `NoOpEventViewerService`). If nothing is + registered, calling `IIssueManager.CaptureException(...)` etc. is a safe no-op — this alone + satisfies "connect/disconnect without crashing." +- `PowerCSharp.Operational` optionally participates in the Features Framework: + `PowerFeatures:Operational:Enabled` (same shape as `PowerFeatures:Cache:...`/ + `PowerFeatures:Sanitization:...`), resolved through the same composite flag chain (code override + → `IFeatureFlagProvider` → environment variable → appsettings → default). This is opt-in wiring, + not a hard dependency — an app can use `Operational` with plain DI registration + (`AddOperational()`/`UseOperational()`) and never touch the Features engine at all. + +--- + +## 8. Reuse Decisions + +- **Sanitization.** `DiagnosticsService`, `DiagnosticsLogger`, and `EventLogWriter`'s + failure-forwarding path all delegate masking and sensitive-data filtering to the already-shipped + `PowerCSharp.Feature.Sanitization.Abstractions` package (`Mask`, `SanitizeForLog`, + `SanitizeForSensitiveData`), rather than reimplementing a sanitization engine. This is the one + place Operational takes a project reference on another PowerCSharp package rather than standing + alone. +- **Correlation id.** No PowerCSharp-wide correlation-id abstraction exists yet. Rather than port or + reimplement one, every call site that would use one (`IssueManager.CaptureException`, + `DiagnosticsLogger.ForwardToEventViewer`, `EventLogWriter.Enqueue`) carries an explicit `// TODO` + marking this as a known v1 gap. `EventLogWriter` falls back to `HttpContext.TraceIdentifier` (or a + fresh GUID when no HTTP context is available) so file names stay unique in the meantime. +- **Static-locator → constructor DI.** The reference implementation resolved several dependencies + through a static service-locator. Every one of those was converted to constructor DI in this + port, with one deliberate, narrowly-scoped exception: `DiagnosticsLogger` resolves + `IDiagnosticsService` from `HttpContext.RequestServices` at each `Log` call, because + `ILoggerProvider.CreateLogger` runs once at host startup — outside any request scope — while + `IDiagnosticsService` is scoped per-request. This is the standard, narrowly-justified pattern for + bridging a singleton-lifetime `ILogger` to a per-request scoped service, not a general-purpose + service-locator reintroduction. +- **`EventLogWriter` as a DI singleton, not a static `Instance`.** The reference implementation used + a hand-rolled static singleton. Every dependency `EventLogWriter` needs + (`IHttpContextAccessor`, `IEventViewerService`, `OperationalOptions`) is itself singleton-safe, so + it is registered as a genuine DI singleton (`services.AddSingleton()`) instead — + a deliberate improvement over the original pattern, not a behavior-preserving port. + +--- + +## 9. Debranding + +Applied as a complete strip, not a rename-only pass: no references of any kind — in code, XML doc +comments, default string literals, config keys, file/namespace names, or this documentation — to +the original client, product, or internal ticket system the reference implementation came from. All +`#if DEBUG` / debug-console scaffolding was removed and replaced with proper `ILogger` usage (e.g. +`RetryPolicyProvider`'s unit-test-host detection uses assembly inspection, not a debug-only branch). +Sentry SDK and third-party issue-tracking framework calls were removed entirely — not renamed and +kept — per the explicit exclusion in §10. + +--- + +## 10.

Open Risks + +- **IP clearance.** Bringing debranded logic derived from a production client codebase into a + public MIT-licensed OSS package requires clearance from that codebase's owner. This document + records the engineering decisions made assuming that clearance is in place; it is not itself + evidence that clearance was obtained, and should be confirmed independently before this package is + published. +- **Correlation-id gap.** Left as a `// TODO` per the decision in §8 — any consumer relying on a + correlation id linking a request's diagnostic events, log lines, and disk event-log files will not + get one from `Operational` v1. Revisit once PowerCSharp ships a correlation-id abstraction. +- **No compiler verification at delivery time.** This package's v1 implementation was authored in + an environment without a .NET SDK available to build or test it. All correctness checking during + authoring was manual code review.

This lets an +engineer or QA tester turn on diagnostics for a single request without touching configuration or +redeploying. + +### `IIssueManager` + +The shared capture surface: enriches exceptions/errors/breadcrumbs with caller context +(`[CallerMemberName]`/`[CallerFilePath]`/`[CallerLineNumber]`) and forwards them to +`IDiagnosticsService`. + +```csharp +public interface IIssueManager +{ + (T Exception, DiagnosticEvent?

AddBreadcrumb(string message, string category = "general", BreadcrumbLevel level = BreadcrumbLevel.Info, IDictionary? data = null); +} +``` + +Implementations must never throw as a result of capturing an issue — a failure to capture must +never surface as a failure of the operation being diagnosed. `IssueManager` (the real +implementation) enforces this by wrapping every forward-to-diagnostics call in a try/catch that +logs a warning and continues. + +### `IEventViewerService` + +A pluggable hook for forwarding sanitized log entries to a platform event log (e.g. the Windows +Event Viewer). The core package ships only `NoOpEventViewerService` — no platform-specific code +lives in the cross-platform core.

PowerCSharp.Operational + +### `DiagnosticsService : IDiagnosticsService` + +Scoped (per-request) implementation. Reads the headers above from `IHttpContextAccessor` once +(`Initialize()`), records events in a `ConcurrentBag`, and filters/sanitizes on +read (`GetEvents()`/`BuildPayload()`). + +Key behaviors: + +- **Errors force full trace on read.** If any `Error`/`Exception` event was captured, `GetEvents()` + escalates to full trace output regardless of the configured `traceLevel` header, so + troubleshooting has the complete picture leading up to the failure. +- **Auto-obfuscation.** Messages matching an IP address, URL, email address, or GUID pattern are + masked automatically even when the caller didn't request it, unless `IsDebugVerbose`. +- **Sanitization is delegated**, not reimplemented: masking uses + `PowerCSharp.Feature.Sanitization.Abstractions`' `Mask(char)`/`Mask(int, char)` extensions, and + sensitive-data filtering on read uses `SanitizeForSensitiveData()`. Operational does not ship its + own masking engine. +- **Static defaults.** `DefaultLogLevel`, `DefaultHttpMaxAttempts`, `DefaultMethodMaxAttempts` are + static properties, set from the most recently constructed instance's `OperationalOptions`. This + lets `DiagnosticsLogger` and `RetryPolicyProvider` — which are not always resolvable within the + same request scope — read the configured defaults without a direct dependency. + +```csharp +public DiagnosticsService(IHttpContextAccessor httpContextAccessor, IOptions options, EventLogWriter eventLogWriter); +``` + +### `IssueManager : IIssueManager` + +Constructor-injects `IDiagnosticsService` and `ILogger`. `CaptureException` merges +a supplied `data` dictionary into `ex.Data` before forwarding, and enriches the diagnostic event +with `caller = "{file}:{line} ({member})"`. A `// TODO` marks where a request/operation correlation +id will attach once PowerCSharp ships a correlation-id abstraction — flagged as a known v1 gap, not +silently dropped. + +### `EventLogWriter` + +Writes diagnostic events to disk as NDJSON, one background task processing a `BlockingCollection` +queue so callers never block on disk I/O. Registered as a DI singleton (not a hand-rolled static +`Instance`) — every dependency here (`IHttpContextAccessor`, `IEventViewerService`, +`OperationalOptions`) is itself singleton-safe. + +- Files are organized by `{LogsBasePath}/{AppName}/{yyyy}/{MM}/{dd}/log_..._{correlationId}.ndjson`. +- Per-file writes are serialized with a `ConcurrentDictionary` of file locks, so + concurrent requests writing to the same file don't corrupt it. +- `Enqueue` is inert (no-op) until `LogsBasePath` is configured. +- On a write failure, the entry is forwarded through `IEventViewerService` as a best-effort + fallback channel, in addition to being logged via `ILogger`. +- `Dispose()` calls `CompleteAdding()` on the queue, letting the background task drain and exit. + +### `EventLogRetentionCleaner` (static) + +Deletes date-partitioned log directories older than `LogsRetentionDays`, on a background `Task.Run`, +tolerating locked files and permission errors (retried on the next pass rather than throwing). +Invoked once at startup by `UseOperational()`. + +### `DiagnosticsLogger : ILogger` / `DiagnosticsLoggerProvider : ILoggerProvider` + +A custom logging sink that forwards `ILogger` calls to `IDiagnosticsService` (in-app diagnostics) +and `IEventViewerService` (platform event log). Because `ILoggerProvider.CreateLogger` runs once at +host startup — outside any request scope — `DiagnosticsLogger` deliberately resolves +`IDiagnosticsService` from `HttpContext.RequestServices` at each `Log` call, rather than +through constructor injection. This is the standard pattern for bridging a singleton-lifetime +`ILogger` to a per-request scoped service, and is the one place in this package that reads from +`RequestServices` directly rather than via constructor DI. + +Every message is sanitized (`SanitizeForLog().SanitizeForSensitiveData()`) before it reaches +diagnostics, disk, or the platform event log. + +### `IRetryPolicyProvider` / `RetryPolicyProvider` + +```csharp +public interface IRetryPolicyProvider +{ + ResiliencePipeline GetPipeline(); + IAsyncPolicy CreatePolicy(string key); + AsyncRetryPolicy GetAsyncPolicy(ILogger? logger, int maxAttempts); + RetryPolicy GetPolicy(ILogger? logger, int maxAttempts); +} +``` + +`GetPipeline()` returns a Polly v8 `ResiliencePipeline` combining exponential +backoff with jitter (decorrelated-jitter shape) and a circuit breaker. Only transient failures are +retried: 5xx responses, `408 Request Timeout`, `429 Too Many Requests`, and +`HttpRequestException` — permanent client failures (400/401/403/404/409/422, etc.) are never +retried. `CreatePolicy`/`GetAsyncPolicy`/`GetPolicy` use the legacy `Polly.Policy` API for +general-purpose (non-HTTP) method retries. + +Under a detected unit-test host (xUnit/NUnit/MSTest assembly present in the current +`AppDomain`), `GetPipeline()` builds a no-op pipeline instead — tests exercising code that calls +through the pipeline don't pay for real backoff delays. The legacy `Policy`-based methods are not +test-host-aware; avoid triggering their retry path (i.e., don't assert on failure/retry behavior) +in fast unit tests. + +### `OperationalServiceCollectionExtensions` + +```csharp +IServiceCollection AddOperational(this IServiceCollection services, IConfiguration configuration); +IApplicationBuilder UseOperational(this IApplicationBuilder app); +``` + +Explicit (no-reflection) registration — works standalone, no dependency on `PowerCSharp.Features`. +Binds `OperationalOptions` from `PowerFeatures:Operational`. When `Enabled` is `false`, registers +NoOp floors for every contract instead: no background writer task starts, no custom +`ILoggerProvider` is added, and the host behaves exactly as if Operational were never referenced. +`UseOperational` eagerly resolves `EventLogWriter` (starting its background task at startup rather +than lazily) and runs one round of `EventLogRetentionCleaner`. + +### `OperationalFeatureModule` (optional) + +An `IFeatureModule` implementation mirroring `CacheFeatureModule`, for hosts that already use +`PowerCSharp.Features` and want Operational's enable/disable flag resolved through the same +composite provider chain (code override → custom flag provider → environment variable → +appsettings → default) as Cache and Sanitization. `FeatureKey = "Operational"`, `Order => 0` — +registered ahead of leaf features that may want to log/capture during their own startup. + +--- + +## 3.

---- - -## [2.0.0] - 2026-06-22 - -### Added - -- **PowerCSharp.Features.Abstractions v1.0.0** — Contracts package: `IFeatureModule`, `IFeatureFlagProvider`, `IFeatureRegistrationContext`, `IFeaturePipelineContext`, `FeatureOptionsBase`, `FeatureDescriptor`, `FeatureTier`, `FeatureFlagValue`, `FeatureFlagSource`. Zero third-party dependencies; targets `netstandard2.0` + `net8.0` so any feature can reference it cheaply. - -- **PowerCSharp.Features v1.0.0** — The Features engine: hybrid auto-scan + explicit module discovery (`FeatureModuleDiscovery`), composite flag resolver (override → custom providers → env vars → appsettings → default), DI orchestration, feature registry, and opt-in diagnostics HTTP endpoint. Entry points: `AddPowerFeatures()` / `UsePowerFeatures()`. Startup feature matrix logged via `ILogger` in `UsePowerFeatures`. - -- **PowerCSharp.BuiltInFeatures v1.0.0** — Bundle of lightweight, runtime-flag-toggled ASP.NET Core capabilities. Initial built-in: **CORS** (`PowerFeatures:Cors`). `AddBuiltInFeatures()` convenience extension opts the bundle into auto-discovery. Any built-in can be disabled and replaced by a custom Pluggable Feature. - -- **PowerCSharp.Feature.Cache.Abstractions v1.3.0** — Framework-agnostic cache contracts and NoOp safe-off floor: `ICacheService`, `IDiskCacheService`, `ICacheStore`, `CacheProvider` enum, `CacheResult`, `CacheMetadata`, `CacheFileKind`, and NoOp implementations (`NoOpCacheService`, `NoOpDiskCacheService`). Targets `netstandard2.0` + `net8.0`. - -- **PowerCSharp.Feature.Cache v1.3.0** — Cache feature module (`CacheFeatureModule`), options (`CacheFeatureOptions`), and `AddCacheFeature()` explicit extension. Always registers the NoOp floor so dependents resolve safely when no provider is active. - -- **PowerCSharp.Feature.Cache.BitFaster v1.3.0** — BitFaster-backed in-memory LRU cache provider. Isolates `BitFaster.Caching` dependency. Targets `netstandard2.0` + `net8.0`. Implements full `ICacheService` sync/async API with performance metrics and stampede protection (`GetOrCreate` / `GetOrCreateAsync`). - -- **PowerCSharp.Feature.Cache.Disk v1.3.0** — Disk-backed LRU cache provider. Atomic writes, cross-process file-lock coordination, background cleanup timer, metadata-aware operations, and `DebugHelper` for troubleshooting. Targets `net8.0`. - -- **`DirectoryExtensions`** — `TrySafeDelete` and related safe directory-deletion helpers in `PowerCSharp.Extensions`. - -- **Comprehensive Features test suite** — `PowerCSharp.Features.Tests`, `PowerCSharp.BuiltInFeatures.Tests`, and `PowerCSharp.Feature.Cache.Tests` covering: engine discovery, CORS module, NoOp floor, BitFaster provider, disk cache (async, cross-process locking, timer, metadata, file kind, validation, LRU eviction). - -- **`.editorconfig`** — Comprehensive coding standards (member ordering, brace style, nullable, indentation) applied across the entire codebase. - -- **Local NuGet feed script** (`scripts/pack-local-feed.sh`) — Packs all projects to a local feed for integration testing with consumer projects (e.g. `PowerCSharp.CleanArchitecture`). - -### Changed - -- **`Directory.Build.props`** — Added `PowerCSharpFeaturesVersion` (1.0.0) and `PowerCSharpFeatureCacheVersion` (1.3.0) alongside the existing `PowerCSharpVersion`. Changed `GeneratePackageOnBuild` to `false` (explicit pack via CI only). -- **`PowerCSharp.Feature.Cache.Abstractions`** — Reorganised into dedicated `Enums` and `NoOp` sub-namespaces. Removed redundant `using` statements. Nullable annotations updated throughout. -- **`DiskCacheOptions`** — Renamed to `DiskCacheFeatureOptions` and moved to the `PowerCSharp.Feature.Cache.Disk` package (was incorrectly in the core Cache package). -- **`DiskCacheService`** — Refactored to use `IDiskCacheService` abstraction; background timer moved to core service for cross-platform compatibility. -- **`BitFasterCacheService`** — Extended with comprehensive sync/async methods and metadata tracking. -- **Member ordering** — All affected files reorganised to follow EditorConfig standards (fields, constructors, properties, methods). -- **Conditional statements** — Block braces applied consistently across `PowerCSharp.Extensions`, `PowerCSharp.Utilities`, and Feature packages. -- **`JsonExtensions`** — Removed duplicate class (consolidated into `JsonElementExtensions`). -- **`OrderClause`** — Extracted to its own file from `DynamicExpressionExtensions`. -- **`AsyncHelper`** — Extended with `ValueTask` support for async-to-sync bridging. -- **Nullable reference type annotations** — Updated in cache abstractions, sample endpoints, and test support files. - -### Fixed - -- **`Console.WriteLine` removed from `PowerFeaturesServiceCollectionExtensions` and `FeatureModuleDiscovery`** — Debug output replaced by proper `ILogger` startup summary in `UsePowerFeatures` → `FeatureDiagnostics.LogMatrix`. -- **`Console.WriteLine` removed from `ObjectExtensions.MapTo`** — Exception in property-copy helper now silenced without writing to stdout. -- **Unused variable warning** in `CacheFeatureModule` — `Assembly.Load` result now uses the discard pattern (`_`). - ---- - -## [Sanitization 1.0.0] - 2026-07-23 - -### Added - -- **PowerCSharp.Feature.Sanitization.Abstractions v1.0.0** — Sanitization engine, contracts, and NoOp safe-off implementation. Migrated and de-branded from an internal reference implementation, then refactored from one large class into concern-based files: `SanitizationEngine.LogInjection.cs` (CWE-117), `SanitizationEngine.FilePath.cs` (CWE-22), `SanitizationEngine.SensitiveData.cs` (CWE-200), `SanitizationEngine.RegexInjection.cs` (CWE-400/CWE-730). Includes `SanitizationExtensions` string extensions (usable with no DI or configuration), `SanitizationSettings`, `SanitizationResult`/`SensitiveDataResult`, and `NoOpSanitizationService`. Targets `netstandard2.0` + `net8.0`. - -- **PowerCSharp.Feature.Sanitization v1.0.0** — Sanitization feature module (`SanitizationFeatureModule`), options (`SanitizationFeatureOptions`), `SanitizationService` / `SanitizationSettingsProvider`, and `AddSanitizationFeature()` explicit extension. No separate provider package (unlike Cache) — registers the real service directly when the feature flag is enabled, `NoOpSanitizationService` otherwise. `ConfigureSanitizationEngine()` bridges DI-resolved settings into the static engine for non-DI call sites. - -- **Comprehensive Sanitization test suite** — `PowerCSharp.Feature.Sanitization.Tests` covering log injection, file-path traversal (strict allowlist and legacy modes), sensitive-data masking, regex/ReDoS validation, extension methods, result-type equality, and feature DI wiring. - -- **`PowerCSharpFeatureSanitizationVersion`** — New independent version family in `Directory.Build.props`, alongside a `sanitization` `package_family` choice in the release `workflow_dispatch`. - -### Fixed - -- **Sensitive-data key masking** — `MaskKeyBasedValues`'s handling of the generic `password`/`token`/`secret`/etc. key-value pattern referenced a capture group that didn't exist on that regex, which always evaluated to an empty mask and silently left the raw secret value in the sanitized output (with the key name dropped). Found while writing tests for the Sanitization feature; the same defect exists in the original reference implementation this was migrated from. Fixed by reconstructing the key prefix the same way the other key-based heuristics in the same method already do. - ---- - -## Version History - -### Future Releases - -#### [2.1.0] - Planned --
