• Match each video's subtitles by exact filename stem using SRT, ASS, SSA or VTT files; reject missing or ambiguous matches before queueing. Add localized controls and documentation.
• Bound memory and processing for reverse/silence trimming, image metadata removal, CSO decompression, EPUB content, PDF wrapping/tables, spreadsheets and nested DOCX tables; improve CSO cancellation.
• Verify protected Debian package copies before privileged installation and use structured shell-menu cleanup markers to prevent path injection.
• Avoid repeated batch output collision scans, remove duplicate queue-control hover text, and update calamine, encoding_rs, ureq and zip.

The committed range includes substantial security, performance and dependency work beyond the issue-fix task title.

Validation: Regression tests were added for subtitle matching and hardening changes; validation was not run during this review.

Summary by CodeRabbit

• New Features
  • Added an option to match subtitle files to each video by filename when adding subtitles to a batch. Matching supports SRT, ASS, SSA, and VTT files in the video’s folder.
  • The app reports when a video has no matching subtitle or has multiple matches. Turn off matching to use one subtitle file for all selected videos.
• Documentation
  • Added guidance on filename matching and resolving match errors.

Walkthrough

AddSubtitles can now match each video with a subtitle file in the same directory by exact, case-sensitive filename stem. The planner reports missing or ambiguous matches before allocating outputs. The interface, localization strings, README, and tests cover the new option and its behavior.

Changes: Batch subtitle matching

Layer / File(s)	Summary
Expose filename matching and its input rules src/options.rs, src/app.rs, src/plan.rs, locales/*.json, README.md	AddSubtitles exposes a filename-matching option and hides the subtitle picker when matching is enabled. Option validation accounts for matching mode. Localized messages and the README describe supported formats, matching rules, and match errors.
Resolve subtitles and build jobs src/jobs.rs, src/exec.rs	When matching is enabled, job planning finds one subtitle per video before output allocation. Missing and ambiguous matches produce path-specific errors. Tests cover per-video matching, serialization, manual subtitle selection, error cases, and generated output tracks.

Merge Risk: Moderate · up to 1ce2d

A new test fails on macOS and Windows CI, which blocks the test workflow on those platforms. The production matching logic is not shown to be affected. Fix the test before merging.

Security architecture risk: Low · up to 1ce2d

Automatic matching changes which adjacent files can become conversion inputs, but missing or ambiguous matches are rejected before outputs are reserved. Imported jobs still require a subtitle path. No introduced security vulnerability was established; incomplete coverage leaves some uncertainty.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — When the user enables matching, an actor able to place files in a selected video's directory can influence the automatically selected conversion input. Discovery accepts supported filename extensions and uses is_file, which follows symlinks; it is not a canonical-path containment guarantee. This establishes adjacent-file influence, not a demonstrated privilege escalation or security vulnerability.

Trust Boundaries and Controls

• observed — Task-list import validates every parsed specification before queueing any of them. The base required a manual subtitle through options validation; the head preserves that requirement with an explicit JobSpec check, while shared edit validation still rejects empty or control-character paths. The queue remains a trusted consumer rather than a second validation boundary, as before this PR.

Resilience and Maintainability Implications

• inferred — Resolution stores paths, not immutable file contents. Replacing or removing a subtitle after planning can change what execution reads or cause failure; retry reuses the stored path. This file-replacement class already existed for manually selected subtitles and is not established here as a newly introduced security vulnerability.

Full details: Title check

Explanation

The title names two of the main changes, batch subtitle matching and dependency refresh, and it also names the security and conversion hardening work. It is broad and lists several changes, but it does not contradict the changeset. The summary of file changes covers subtitle matching in options, jobs, plan, app and exec, and the PR objectives also cover hardening and dependency updates. The title is partially related in that it lists the main change first, but the hardening and dependency items are only described in the objectives and not in the file summaries provided.

Full details: Docstring Coverage

Explanation

Docstring coverage is 37.50% 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 8 functions across 5 files. (7 skipped: 7 unsupported.)

Resolution

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

- Around line 719-730: Update the case-mismatch fixture in the subtitle matching
test in `src/jobs.rs`: use a different extension for `Two` so it cannot collide
with the later `two.srt` on case-insensitive filesystems. Preserve the
missing-match assertion and ensure adding `two.srt` and `two.vtt` still produces
the intended ambiguous-match result.
