1. SSL_CERT_DIR path mismatch 🐞 Bug ✓ Correctness
Description
UnixCertificateManager compares SSL_CERT_DIR entries against Path.GetFullPath(prettyCertDir), but
prettyCertDir may contain the literal "$HOME", so a correctly-configured SSL_CERT_DIR using an
absolute path won’t match and trust is incorrectly treated as partial/failing. It also uses
OrdinalIgnoreCase on Unix paths, which can wrongly treat different directories as the same on
case-sensitive filesystems.
Code

src/Shared/CertificateGeneration/UnixCertificateManager.cs[R355-376]

                ? Path.Combine("$HOME", certDir[homeDirectoryWithSlash.Length..])
                : certDir;

-            if (TryGetOpenSslDirectory(out var openSslDir))
+            var hasValidSslCertDir = false;
+
+            // Check if SSL_CERT_DIR is already set and if certDir is already included
+            var existingSslCertDir = Environment.GetEnvironmentVariable(OpenSslCertificateDirectoryVariableName);
+            if (!string.IsNullOrEmpty(existingSslCertDir))
+            {
+                var existingDirs = existingSslCertDir.Split(Path.PathSeparator);
+                var certDirFullPath = Path.GetFullPath(prettyCertDir);
+                var isCertDirIncluded = existingDirs.Any(dir =>
+                {
+                    if (string.IsNullOrWhiteSpace(dir))
+                    {
+                        return false;
+                    }
+
+                    try
+                    {
+                        return string.Equals(Path.GetFullPath(dir), certDirFullPath, StringComparison.OrdinalIgnoreCase);
+                    }
Evidence
The code intentionally rewrites certDir into a display-friendly "$HOME/..." form, then mistakenly
uses that display value for full-path comparison against the environment variable entries; "$HOME"
is not expanded by Path.GetFullPath and will not equal the real absolute directory path.
Additionally, using OrdinalIgnoreCase can produce false positives on case-sensitive filesystems.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
Unix SSL_CERT_DIR detection uses a display-only path (prettyCertDir, which may include the literal `$HOME`) for Path.GetFullPath comparisons and uses OrdinalIgnoreCase on Unix, causing false negatives/positives when deciding whether SSL_CERT_DIR already includes the cert directory.

### Issue Context
This logic controls whether the tool reports trust as partial vs full and what guidance it prints.

2. Trust failures overwritten 🐞 Bug ✓ Correctness
Description
TrustCertificateCore overwrites sawTrustFailure with !hasValidSslCertDir, which can clear earlier
failures (e.g., NSS DB trust failures) and incorrectly return TrustLevel.Full. This makes the tool
report success even when some trust steps already failed.
Code

src/Shared/CertificateGeneration/UnixCertificateManager.cs[R408-409]

+            sawTrustFailure = !hasValidSslCertDir;
        }
Evidence
sawTrustFailure is used earlier to record any failures across trust steps and to log partial
success; later it is unconditionally reassigned based solely on hasValidSslCertDir, losing the prior
failure state.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
The new SSL_CERT_DIR validation overwrites `sawTrustFailure`, masking failures from earlier trust steps and allowing an incorrect `TrustLevel.Full`.

### Issue Context
`sawTrustFailure` aggregates failures from dotnet store trust, OpenSSL rehash, and NSS DB trust operations.

3. Event format-string crash 🐞 Bug ⛯ Reliability
Description
CertificateManagerEventSource event 111’s message uses placeholder {2} but only two payload
arguments are supplied, and ReporterEventListener always calls string.Format on the message. With
this PR enabling the listener at LogAlways in non-verbose runs, emitting event 111 will throw a
FormatException and can crash dotnet-dev-certs.
Code

src/Tools/dotnet-dev-certs/src/Program.cs[R127-135]

+                    var listener = new ReporterEventListener(reporter);
                    if (verbose.HasValue())
                    {
-                        var listener = new ReporterEventListener(reporter);
                        listener.EnableEvents(CertificateManager.Log, System.Diagnostics.Tracing.EventLevel.Verbose);
                    }
+                    else
+                    {
+                        listener.EnableEvents(CertificateManager.Log, System.Diagnostics.Tracing.EventLevel.LogAlways);
+                    }
Evidence
Program now always enables an EventListener (LogAlways when not verbose), ReporterEventListener
formats event messages via string.Format, and event 111 has a placeholder index that cannot be
satisfied by the two arguments passed to WriteEvent—so formatting will throw when that event is
written (e.g., when OpenSSL directory detection fails).

### Issue description
Event 111’s format string references `{2}` but only two arguments are passed to `WriteEvent`, and the console event listener always calls `string.Format`, which will throw and can terminate the tool.

### Issue Context
This PR enables the listener even when not verbose (LogAlways), making this crash user-visible.

4. NssDb missing primary constructor 📘 Rule violation ✓ Correctness
Description
The NssDb type was changed from a C# 12 primary constructor to a traditional constructor with
backing fields, despite being a simple parameter-to-member assignment pattern. This violates the
repository convention to prefer primary constructors for this scenario and adds unnecessary
boilerplate.
Code

src/Shared/CertificateGeneration/UnixCertificateManager.cs[R994-1006]

+    private sealed class NssDb
    {
-        public string Path => path;
-        public bool IsFirefox => isFirefox;
+        private readonly string _path;
+        private readonly bool _isFirefox;
+
+        public NssDb(string path, bool isFirefox)
+        {
+            _path = path;
+            _isFirefox = isFirefox;
+        }
+
+        public string Path => _path;
+        public bool IsFirefox => _isFirefox;
Evidence
PR Compliance ID 9 requires using C# 12 primary constructors for simple constructor-to-member
assignment patterns. The updated NssDb implementation introduces explicit fields and a full
constructor for two simple values, which is the exact pattern the rule aims to avoid.
