Summary

Promotes develop to main. develop merges into main with no conflict, so develop heads this pull request directly.

• Name WebVTT as the Reason HandBrake Encodes Without Subtitles #1232: names WebVTT, not the ASS conversion, as the reason HandBrake encodes without subtitles, in a ProcessFile.cs comment and ARCHITECTURE.md.
• Compare Output Tracks and Normalized Process Logs Between Regression Runs #1233: check_results.py --baseline also compares each file's output tracks and the two normalized process logs between regression runs. It touches RegressionTests/ and OPERATIONS.md only.
• Fail a Track Dump Present in One Run Only #1235, Report a Shared Track Dump Name as an Unverified Track Check #1236, Refer to the Log Checks Without Counting Them #1237, and State Why a File No Run Read Compares Only Its Outcome #1238: fixes this promotion's review found in Compare Output Tracks and Normalized Process Logs Between Regression Runs #1233. A file one run dumped and the other did not fails, a shared dump name reports an unverified track check rather than a traceback, and the README states how files are keyed and compared.

None of these changes alters the shipped binary's behavior, so no regression run is owed for this promotion. OPERATIONS.md "Ship a change" step 3 scopes a run to changes in processing, sidecar, media-tool, or language-tag code, or the image.

Merging this closes #1219 through #1233's squash commit. That issue's last step, reducing the host configuration repository's recipes to pointers at the new checks, is tracked in the corpus handoff.

The comments label covers the code comment #1232 rewrote, which the prose gate reads as an added comment line.

Walkthrough

The regression comparison now checks output tracks and normalized process logs alongside per-file outcomes. The documentation and a code comment also update the description of HandBrake subtitle handling.

Changes: Regression run comparison

Layer / File(s)	Summary
Log and track parsing RegressionTests/check_results.py, RegressionTests/tests/test_check_results.py	The comparison reads process logs, extracts tool versions and output tracks, and detects ambiguous basenames. Tests cover track extraction and parsing cases.
Normalized logs and bitrate differences RegressionTests/check_results.py, RegressionTests/tests/test_check_results.py	Normalized log lines are compared without relying on their order. Bitrate differences are noted for matching outcomes in the specified processing states; tests cover normalization and bitrate cases.
Run comparison and documented checks RegressionTests/check_results.py, RegressionTests/tests/test_check_results.py, RegressionTests/README.md, OPERATIONS.md	Track and log findings are added to the run comparison. The README and runbook document the expanded checks, and tests cover comparison outcomes and missing inputs.

HandBrake subtitle descriptions

Layer / File(s)	Summary
Subtitle behavior descriptions ARCHITECTURE.md, PlexCleaner/ProcessFile.cs	The documentation and code comment now state that HandBrake drops some subtitle data, including WebVTT, rather than converting subtitles to ASS. The documentation retains the description of restoring original subtitle tracks.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · previous review 03b14

The regression baseline comparison can crash with a traceback instead of reporting differences when two logged paths share a filename. This only affects the regression tooling, not the shipped binary, and the fix is small.

Full details: Out of Scope Changes check

Explanation

The regression comparison code, tests, README, and runbook implement #1219. The ProcessFile.cs comment and ARCHITECTURE.md correction implement the separate #1232 change explicitly stated in the current PR description. No changed file lacks a connection to the PR’s stated objectives.

Full details: Linked Issues check

Explanation

#1219’s track and log comparisons, runbook and README updates, and constructed-log tests are present. However, RegressionTests/check_results.py does not normalize temporary-file suffixes in normalized_lines, although #1219 names them as run-varying log fields. test_run_noise_normalized does not test that field. This leaves a stated log-comparison requirement unmet.

Resolution

Normalize the temporary-file suffixes specified by #1219 in normalized_lines and add a constructed-log test that varies the suffix and verifies that the normalized logs match.

Full details: Docstring Coverage

Explanation

Docstring coverage is 52.38% 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 21 functions across 3 files. (3 skipped: 3 unsupported.)

Resolution

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

High-Level Assessment

Keeping track and log comparisons in the existing baseline checker is appropriate: they use the same run artifacts and belong beside outcome comparison. Separate host-side recipes would retain fragmented checks without improving the shipped application.

1. Files without track dumps pass unchecked ✓ Resolved

Description

track_differences() treats an absent file as an empty track list, so it reports no difference when
a file has no dump on either side, or has an empty dump on one side and no dump on the other. If
each run has a dump for at least one other file, compare_logs() skips its run-wide unverified
check, and the comparison can succeed without track evidence for those files.

An active moderate bug in RegressionTests/check_results.py can let comparisons pass without verifying tracks for a missing per-file dump, so changes are needed.

What changed in this PR

This promotion moves develop into main and carries two changes. The first corrects the reason HandBrake encodes without subtitles, naming WebVTT rather than the ASS conversion. The second extends the regression harness so check_results.py --baseline also compares each file's output tracks and the two normalized process logs. Together they close issue #1219, which moves the host repository's track and log checks into RegressionTests/.

Changes:

• ProcessFile.cs and ARCHITECTURE.md: the HandBrake subtitle comment now names WebVTT, the IETF tags, and embedded closed captions as what HandBrake drops.
• check_results.py: adds per-file output track comparison, normalized process log comparison, and a bitrate-shift note.
• Tests and docs: new unit tests on constructed log lines, plus updates to RegressionTests/README.md and OPERATIONS.md describing the new checks.

File	Description
RegressionTests/​tests/​test_check_results.py	Adds unit tests for track dumps, log normalization, bitrate noise, and shared-name refusal. Updates two tests to expect failure on a missing log.
RegressionTests/​README.md	Documents the output track check, the normalized log check, and the exit code rules.
RegressionTests/​check_results.py	Implements track extraction, track differences, log normalization, and the log comparison in --baseline mode.
PlexCleaner/​ProcessFile.cs	Rewords the HandBrake subtitle comment to name WebVTT. Comment-only change.
OPERATIONS.md	Adds the track and log checks to "Ship a change" step 3.
ARCHITECTURE.md	Replaces the ASS conversion reason with the WebVTT reason in the HandBrake section.

In code that hasn't changed since last review

Flag result files with no track dump on either side

RegressionTests/​check_results.py:270

A file with a result in both runs but no Debug track dump on either side is never compared. track_differences() only walks names that have a dump, and the undumped check only tests whether a whole run has no dumps. So one file's tracks can go unchecked while the others pass. Decide how a file that never reads media should be reported, then flag each result file with no dump on either side and add a regression test for it.

[Medium severity] Flag result files with no track dump on either side

Declined, with the evidence in #1236's body. Each tool read logs its Reading media info from tools line before the tools run (SidecarFile.cs GetToolInfo), so a file neither run dumped was never read in either run, and has no output tracks to compare. A file that fails before its first read records such a result, such as a by-extension remux failure, a rename collision, or a read-only file. Requiring a dump there failed two runs of one build against each other, which the local review of #1236 showed before it was dropped. The file's outcome is still compared, and a file one run read and the other did not already fails, per #1235.
