- feat: provide ARM64 binaries (#2243)
- fix: Wrapper executable not found (#4134)
- fix: Cannot remove service with status "Not Installed" - Uninstall button greyed out (#2904)
- fix(core): XmlServiceValidator.TryValidate / JsonServiceValidator.TryValidate - Compares string.Length (chars) against MaxConfigFileSizeBytes (bytes), allowing 2-3x oversized payloads with multibyte UTF-8 content (#1441)
- fix(core): AppConfig.cs - Doc comment references non-existent constant 'MaxBulkOperationParallelism' (actual is 'DefaultMaxBulkOperationParallelism') (#1445)
- fix(core): AppConfig.cs - MaxPreLaunchRetryAttempts = int.MaxValue is inconsistent with bounded MaxMaxRestartAttempts (100_000); allows unbounded retry loops (#1446)
- fix(core): AppConfig.cs - Confusingly similar names: DefaultStopTimeout (5s) vs DefaultServiceStopTimeoutSeconds (60s) (#1448)
- fix(core): ProcessKiller.cs - parentProcess.WaitForExit return value ignored; inconsistent with KillProcessTree/WalkAndKillChildren which log on timeout (#1449)
- fix(core): ResourceHelper.cs - ShouldCopyResource XML doc lists 'targetFileName' as out parameter, but the actual signature has no such parameter (#1453)
- fix(core): Helper.IsServiceNameValid - missing length check inconsistent with ServiceValidationRules.Validate (allows long names through start/stop/uninstall paths) (#1457)
- fix(core): Logger.FormatException - 'truncation to LoggerMaxFormattedExceptionLength' overshoots by 14+ chars (writes '... [truncated]' AFTER setting Length) (#1458)
- fix(core): AppConfig.cs - Static constructor invariant check between two const ints is dead code (compile-time folded) (#1460)
- fix(core): ServiceHelper.CalculateStopTimeout - Math.Max(total, floor) is always 'total' (dead floor guard) (#1462)
- fix(core): Logger.Log() - log entry timestamps reuse '_useLocalTimeForRotation' flag, conflating rotation policy with log formatting (#1464)
- fix(core): Helper.Quote() - whitespace-only inputs are coerced to empty quotes; literal-whitespace arguments cannot be passed (#1465)
- fix(core): SecureData.Encrypt - plainBytes allocated outside try, not zeroed on early failure (Aes.Create / aes.Key throws) (#1488)
- fix(core): StringHelper.cs - unused 'using System.Text.RegularExpressions' import (#1490)

- fix(core): SecureData.Decrypt - 'Returning original input' log message contradicts the immediately-thrown SecureDataIntegrityException (#1509)
- fix(core): ProtectedKeyProvider.GetOrGenerate - inconsistent retry backoff between IOException (exponential) and UnauthorizedAccessException (fixed 100ms) (#1512)
- fix(core): AppConfig.AllowLegacyV1Decryption - documented as a runtime migration toggle but is a static-readonly hard-coded false (no runtime override) (#1517)
- fix(core): AppConfig.ResolveExe - XML doc claims it throws FileNotFoundException but the implementation never throws (#1518)
- fix(core): Helper.WriteFileAtomic / WriteFileAtomicCore - duplicated 'retries = 3' and '100ms backoff' magic numbers across sync and async (#1522)
- fix(core): AppConfig.cs - TargetFramework field throws unconditionally even though it is only consumed inside #if DEBUG blocks (#1525)
- fix(core): SecureData.Decrypt - legacy fallback path emits two redundant 'returning as plaintext' warnings on a single decrypt failure (#1526)
- fix(core): ProcessKiller.KillParentProcesses - parent Process handle opened twice (once for StartTime, then re-opened to Kill) (#1527)
- fix(core): ProcessKiller.WalkAndKillChildren / KillParentProcesses - generic Logger.Warn drops the Exception (no stack), inconsistent with Logger.Error sites in the same file (#1528)
- fix(core): StringHelper.cs - XML doc cref points to wrong namespace 'Servy.Core.Security.EnvironmentVariableParser' (#1534)
- fix(core): ServiceValidationRules.Validate - service-dependency errors are joined into one Errors entry while every other check adds individual strings (#1547)

- fix(core): Logger.cs fallback log entries - inconsistent timestamp format vs. main log (no TZ marker) (#1559)
- fix(core): NativeMethods.ValidateCredentials - 'if (username.Contains("\"))' is dead-conditional after regex pre-check, plus dead initialisations of 'domain'/'user' (#1563)
- fix(core): NativeMethods.ValidateCredentials - generic catch wraps Exception in SecurityException without preserving inner exception (#1575)
- fix(core): ProcessHelper.ResolvePath - throws InvalidOperationException but IProcessHelper XML doc declares ArgumentException (#1583)

- fix(core): XmlServiceValidator vs JsonServiceValidator - asymmetric parse-failure logging and inconsistent error wording across symmetric API pair (#1595)

- fix(core): NativeMethods.GetFileIdentity - 4KB prefix-digest false-negatives on files with identical headers (e.g. rotated logs with same log prologue) (#1638)

- fix(core): EnvironmentVariableParser / EnvironmentVariablesValidator - delimiter array { ';', '\r', '\n' } duplicated between parser and validator (#1642)
- fix(core): ServiceControllerWrapper.BuildDependencyTree - ServicesDependedOn[] disposed twice on happy path (loop + finally) (#1643)
