Skip deleted files and prune missing entries when registering invalid files, and log a settings-file or results-file write failure without ending the run.

• RegisterInvalidFiles does not add a result whose state has FileDeleted to FileIgnoreList.
• With RegisterInvalidFiles on, entries whose file no longer exists are pruned, only when the entry's parent folder exists, so an unmounted share keeps its entries. The settings file is rewritten when the list changed.
• A failed write of the settings file or the --resultsfile is logged as an error and the other write is still attempted. ProcessFiles(fileList, out bool writeFailed) reports it apart from the processing result.
• The process command still runs DeleteEmptyFolders() after a write failure and exits with an error code. Monitor ignores writeFailed, so monitoring keeps running.
• The results log placeholder {Program.Options.ResultFile} is corrected to {ResultsFile}.
• Tests in PostRunWriteTests.

Documentation (ARCHITECTURE.md Suspect Branches entries S12 and S13, diagram redraws, HISTORY.md) is deferred to one final docs pull request by the maintainer's choice, so this pull request does not touch them.

Pre-existing findings, filed

• DeleteFailedFile does not set FileDeleted when only the sidecar delete fails: Set FileDeleted When Only the Sidecar Delete Fails in DeleteFailedFile #1116

Deferred, filed

• Pruning edge cases, a never-retried monitor settings write, and test gaps for the exit-code and Monitor paths, all raised by the last local pass: Harden FileIgnoreList Pruning and Post-Run Write Retry #1120

Local review: four passes. The edit budget is spent, so the last pass's findings are the deferred issue above.

Walkthrough

Post-processing now skips deleted files during invalid-file registration and reports failures when saving settings or writing the results file. Tests cover registration behavior and successful and failed writes.

Changes: Post-processing write handling

Layer / File(s)	Summary
Invalid-file registration and write outcomes PlexCleaner/Process.cs, PlexCleanerTests/PostRunWriteTests.cs	RegisterInvalidFiles skips deleted files and saves settings only when the ignore list changes. FinishProcessing returns false when settings or results writing fails. Tests cover these cases and successful results-file creation.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Full details: Title check

Explanation

The title names three changes: skipping deleted files, pruning missing entries, and logging post-run write failures. The raw summary describes skipping deleted files in RegisterInvalidFiles and logging/handling write failures in FinishProcessing and ProcessFiles. It does not describe pruning missing entries. The PR objectives say existing ignore-list entries remain unchanged and pruning is out of scope. The title is therefore partially related: two of the three named changes match the changeset, and the 'Prune Missing Entries' clause describes something not present in the changeset.

Resolution

Remove 'Prune Missing Entries' from the title. For example: 'Skip Deleted Files and Log Post-Run Write Failures', which matches PR #1117 and the objectives.

High-Level Assessment

Keep the post-run handling in Process: it preserves independent write attempts and lets existing process and monitor callers handle the failure status without changing their cleanup flow. A separate writer abstraction would add complexity for this focused change.

• Extracts post-run handling into FinishProcessing and ignore-list registration into RegisterInvalidFiles. Deleted verification failures no longer create ignore-list entries; settings and results write exceptions are logged and cause a false return without preventing the other write attempt. Corrects the results-file log placeholder.

1. Deleted paths stay on the ignore list ✓ Resolved

Description

RegisterInvalidFiles filters only the incoming failed results and never removes a path already
present in FileIgnoreList. When a deleted file was registered by an earlier run, the existing
entry survives this processing and continues to suppress that path.

Code

PlexCleaner/Process.cs[R706-710]

+        foreach (
+            ProcessResultJsonSchema.ProcessResult item in failedResults.Where(item =>
+                !item.State.HasFlag(SidecarFile.StatesType.FileDeleted)
+            )
+        )

Evidence

The new filter excludes only deleted items from the current failedResults collection, while the
added test explicitly asserts that an already-existing deleted.mkv entry remains in
FileIgnoreList. This matches the rule's failure condition that a deleted file path remains
registered.

Agent prompt

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

## Issue description
`RegisterInvalidFiles` skips newly processed results marked `FileDeleted`, but it preserves existing deleted paths in `FileIgnoreList`. This leaves stale entries behind after a deleted file is processed.
## Fix Focus Areas
- PlexCleaner/Process.cs[704-716]
- PlexCleanerTests/PostRunWriteTests.cs[78-95]
## Recommended Fix
Before or during invalid-file registration, remove existing `FileIgnoreList` entries whose corresponding paths no longer exist, while preserving valid entries. Update the settings file when stale entries are removed, and add or adjust a test proving that an existing entry for a deleted file is removed.

2. The title capitalizes middle and 📘 Rule violation ✧ Quality

Description

The pull request title uses and as a capitalized principal word instead of the documented
lowercase bind-word style. The title is Skip Deleted Files and Log Post-Run Write Failures, so the
conjunction appears in the middle and does not match the stated format.

Code

PlexCleaner/Process.cs[596]

Evidence

The PR title capitalizes the middle conjunction and, while the checklist requires short bind words
to remain lowercase unless they are first or last.

[ptr727]

Answering both open Qodo findings.

1. Deleted paths stay on the ignore list (Requirement gap)

Declined, a maintainer decision. The maintainer's decision on #1080 reads: "skip results whose file was deleted when registering invalid files. Existing ignore-list entries are left as they are." Pruning existing entries is explicitly out of scope, see #1080. RegisterInvalidFiles_ExistingEntry_IsKept pins that behavior.

2. The title capitalizes middle and (Rule violation)

Not real. The title is "Skip Deleted Files and Log Post-Run Write Failures", and and is already lowercase in it. A hyphenated compound capitalizes both parts unless the second is a short preposition, and Run is not one, so Post-Run is correct.

🟡 Changes recommended

A test gap remains for verifying that the settings and results writes are attempted independently when both features are enabled, leaving an active coverage issue.

Follow-up Comments

Add a test where the settings write fails and the results file is set.

102-102: Trivial · Functional Correctness · Quick win

Add a test where the settings write fails and the results file is set.

FinishProcessing_SettingsWriteFails_ReturnsFalse sets ResultsFile to string.Empty, so the results write never runs. An early return after a settings failure would still pass this test. A test that sets ResultsFile to a real path and asserts that the results file exists would detect that regression.

Suggested test

+    [Fact]
+    public void FinishProcessing_SettingsWriteFails_WritesResultsFile()
+    {
+        // A directory at the settings path makes the write throw
+        Program.Options.SettingsFile = Path.Combine(_directory, "settings.json");
+        Program.Options.ResultsFile = Path.Combine(_directory, "results.json");
+        _ = Directory.CreateDirectory(Program.Options.SettingsFile);
+        Program.Config.VerifyOptions.RegisterInvalidFiles = true;
+        ProcessResultJsonSchema resultsJson = new();
+        resultsJson.Results.Results.Add(
+            CreateResult("failed.mkv", SidecarFile.StatesType.VerifyFailed)
+        );
+
+        _ = Process.FinishProcessing(resultsJson, true).Should().BeFalse();

Add a test alongside FinishProcessing_SettingsWriteFails_ReturnsFalse that sets
ResultsFile to a real path, causes the settings write to fail, and asserts
FinishProcessing still returns false and creates the results file. This verifies
that a settings-write failure does not skip the results write.

Update on the earlier answer to Qodo finding "1. Deleted paths stay on the ignore list": the maintainer changed the decision, so this finding is now accepted. The latest push prunes FileIgnoreList entries whose file no longer exists, only when the entry's parent folder exists, covered by RegisterInvalidFiles_MissingFileInExistingFolder_IsPruned. Edge cases of the pruning rule are tracked in #1120.
