Fixes three findings raised on the 3.23 promotion pull request #1140. The maintainer chose to fix the whole class before the promotion merges.

Problem

• A re-encode or deinterlace rewrites the media but kept the Verified and BitrateExceeded flags of the media it replaced. On a later run Verify(true) then skipped the new media, and a stale BitrateExceeded stayed. This was already on main.
• SidecarFile.Open() merged the whole seeded state back after Read() reset a stale sidecar to FileModified, restoring Verified onto media the sidecar hash says changed. Keep the Seeded State When a Renamed File Has a Sidecar #1121 introduced this.
• SetRepairedState() can leave Repaired set without Verified after a bitrate tool error, which trips Debug.Assert(!Repaired) before the next repair in a debug build. Skip Repeat Conversions and Keep Bitrate State Current #1125 added this path.

Change

• SidecarFile.VerifyStates names the verify results: Verified, VerifyFailed, RepairFailed, BitrateExceeded, and PostDecodeTimestamps.
• ReEncode() and DeInterlace() clear them when they replace the file. The process pipeline runs these before VerifyAndRepair(), so the same run verifies the new media and measures its bitrate.
• Open() drops them from the seed when the media differs from the sidecar.
• Repaired stays as history. The !Repaired asserts before a repair are removed, and every site that sets VerifyFailed clears Repaired, so the assert in the VerifyFailed skip still holds.
• RemoveClosedCaptions() keeps them. Removing the caption NAL units leaves the decoded frames unchanged, and the step can run again after VerifyAndRepair() in the repeat cleanup, so clearing there would cost a whole-file verify on every run.
• FakeTools.ReadSidecarState replaces the per-class sidecar state readers.
• ARCHITECTURE.md and HISTORY.md 3.23 describe the new behavior.

Tests

• ReplaceOriginalTests seeds verify states before a successful DeInterlace() and ReEncode(), and asserts each flag is cleared. The ReEncode() cases assert the persisted sidecar too.
• SidecarRenameStateTests seeds every verify flag over a stale sidecar and asserts Open() drops them.
• The full suite passes locally.

Local review

Four strict passes ran before review. The third pass found that a SidecarPath() test helper duplicated SidecarFile.GetSidecarName(), fixed in 253d243, and the fourth pass found nothing. A fifth pass covered the fix for Qodo's DeInterlace test finding in 482fb69 and found nothing.

Pre-existing findings, not filed:

• PlexCleanerTests/ToolChangeSenseTests.cs:83 (pre-existing, consolidation): reads the sidecar state inline instead of FakeTools.ReadSidecarState.
• PlexCleanerTests/RenameCollisionTests.cs:253 (pre-existing, test coverage): the remux refresh fails without a MediaInfo fake, so the test does not assert the step result.
• PlexCleanerTests/SidecarRenameStateTests.cs:108 (pre-existing, test coverage): no test calls the default Open() over a stale sidecar, so the modified = true forced update in SidecarFile.Open() is unpinned. Raised by CodeRabbit.

Declined on evidence: an extra whole-file caption or interlace scan can follow a rewrite that clears Verified, for an old sidecar or a QuickScan run. Setting ScannedCaptions or ScannedInterlace without a scan would record a scan that never ran, and the scan gives a correct result on the new media.

Closes on promotion: none. The findings are on #1140.

Walkthrough

The change clears verification flags when sidecar state belongs to different media and after re-encoding or deinterlacing. It also clears Repaired in verification-failure paths and adds tests for in-memory and persisted state.

Reverify Media After Re-Encode or Deinterlace

🐞 Bug fix 🧪 Tests 📝 Documentation 🕐 20-40 Minutes

AI Description

• Clear file-specific verify results after re-encoding or deinterlacing so replacement media is
 checked.
• Prevent stale sidecars from restoring verify results; preserve repair history and valid
 caption-removal results.
• Add regression tests and document the revised state lifecycle.

High-Level Assessment

The following are alternative approaches to this PR:

1. Tie verify results to a media fingerprint

• ➕ Could invalidate results automatically when media content changes, including in future rewrite paths.
• ➖ Requires sidecar compatibility work and more complex rules for remuxes and caption removal.

Recommendation: Keep the targeted invalidation with a shared flag mask. It addresses the known replacement and stale-sidecar paths without making every media mutation trigger an expensive whole-file verification; a fingerprint scheme is worth considering only if more rewrite paths expose the same problem.

1. Deinterlace test passes after refresh fails ✓ Resolved

Description

DeInterlace_ReplacesOriginalOnlyAfterLanguageRestore asserts the cleared in-memory flags but does
not assert that DeInterlace() succeeds or that the flags reach the sidecar. In its success case,
the test's unfaked MediaInfo refresh can return false after the file is replaced and the flags are
cleared, so the new assertion passes without exercising a completed refresh.

Code

PlexCleanerTests/ReplaceOriginalTests.cs[R140-146]

+            _ = processFile
+                .State.Should()
+                .Be(
+                    SidecarFile.StatesType.DeInterlaced
+                        | SidecarFile.StatesType.ReMuxed
+                        | SidecarFile.StatesType.Repaired
+                );

Evidence

The test explicitly notes that the unfaked MediaInfo refresh fails and omits a result assertion,
while the production method sets the state before refresh and returns false if refresh fails.

The deinterlace success case checks only in-memory state even though its media refresh fails, leaving the persisted state untested.
## Fix Focus Areas
- PlexCleanerTests/ReplaceOriginalTests.cs[125-146]
## Recommended Fix
Provide the fake tool data needed for the post-replacement refresh, assert that `DeInterlace()` returns true in the success case, and assert the expected flags in the persisted sidecar.

Answering Qodo comment-only finding (1): "1. Deinterlace test passes after refresh fails" at PlexCleanerTests/ReplaceOriginalTests.cs. Fixed in 482fb69: the success case completes the refresh and asserts the result and the persisted sidecar state.

🟡 Changes recommended

An active nit remains because the test duplicates sidecar-path logic instead of reusing the production helper, risking divergence if naming changes.

Add a default Open() test for stale media.

108-108: Trivial · Maintainability & Code Quality · Quick win

Add a default Open() test for stale media.

Open_SeededVerifyStatesOverStaleSidecar_DropsVerifyStates calls Open(true), so modified is already true when the stale-media block at PlexCleaner/SidecarFile.cs:242-246 runs. Removing modified = true from that block leaves this test passing. The test still covers the seeded &= ~VerifyStates line. No test calls the default Open() on stale media.

A persisted FileModified state matches the merged state after Verified is dropped. The sidecar is rewritten only through the forced update. This test exercises that path:

Suggested test

+    [Fact]
+    public void Open_SeededVerifyStatesOverStaleSidecarWithoutForce_RewritesSidecar()
+    {
+        Assert.SkipWhen(OperatingSystem.IsWindows(), "The fake tools are shell scripts");
+        string mediaFile = FakeTools.CopyUnverifiedSample(
+            _directory,
+            SidecarFile.StatesType.FileModified
+        );
+        string sidecarPath = Path.Combine(_directory, "name.PlexCleaner");
+        string before = File.ReadAllText(sidecarPath);
+        File.AppendAllText(mediaFile, "changed");
+
+        FakeTools.WriteSampleToolData(_directory);
+
+        SidecarFile sidecarFile = new(mediaFile) { State = SidecarFile.StatesType.Verified };
+        _ = sidecarFile.Open().Should().BeTrue();
+
+        _ = sidecarFile.State.Should().Be(SidecarFile.StatesType.FileModified);
+        _ = File.ReadAllText(sidecarPath).Should().NotBe(before);

Answering CodeRabbit review on 482fb69, nitpick (1): "Add a default Open() test for stale media" at PlexCleanerTests/SidecarRenameStateTests.cs:108. Listed in the body under "Pre-existing findings, not filed". The modified = true forced update on stale media predates this change, which only moved it inside the same block, and no test covered the default Open() on stale media before it either.
