Fixes #132.

Problem

CaptureExecutionSnapshot omitted the newer DubbingSessionOptions export flags, and even the previously-captured ExportFormat was never read by the export resume gate. As a result, a cached export was resumed even when the user changed audio, subtitle, or encoder flags, silently ignoring user intent unless --force-rerun was passed. Identified in review of PR #105.

Changes

  1. Snapshot capture: CaptureExecutionSnapshot now records ApplyTimbrePolish, RestoreOriginalPan, MatchOriginalLoudness, BurnInSubtitles, SubtitleSource (normalized), SubtitleFormats (normalized), and VideoEncoder, plus the previously-latent ExportFormat.
  2. Resume gating: wired those flags into the actual resume decision. A new ExportResumeGating helper is the single source of truth for the gating key/value set. The per-run ExportManifest gained a nullable ExportManifestGating persisting these values. StageArtifactResumeEvaluator.CanResumeStageAsync reads the prior export run's manifest and refuses to resume when any gating flag differs from the current snapshot; HasValidExistingArtifactsAsync awaits the async gate. Older manifests without gating data fail toward resume (safe fallback).
  3. Default-path fix (from review): collapsed a subtitle-format token divergence where the default/null path emitted "default" on the snapshot side but resolved "Srt" on the manifest side, causing spurious reruns of unchanged default-subtitle exports. Both sides now compare raw-to-raw via a single token producer; ExportStageRequest.RawSubtitleFormats carries the caller's original request separately from the resolved formats used for rendering.

Testing

  • dotnet build Trackdub.slnx: 0 warnings / 0 errors (warnings-as-errors)
  • dotnet test Trackdub.slnx: all projects green (Application.Tests 848; Sdk.Tests 405, 2 FFmpeg-smoke skips), including new Application-layer tests that drive the real resume path and default-path tests
  • dotnet format Trackdub.slnx --verify-no-changes: clean

Notes

  • This branch also bumps the .NET SDK pin in mise.toml (10.0.302 -> 10.0.401). The older SDK's Roslyn compiler was too old for the repo's analyzers and the repo does not build without it; the new pin matches global.json rollForward and CI.
  • Non-blocking observation: ExportStageRequest.RawSubtitleFormats is an optional null-defaulted parameter, so a hypothetical future caller that omits it could persist the "default" gating token regardless of what it rendered. Only DubbingPipelineEngine constructs this request today and sets the field correctly, so this is latent, not a live bug.

Summary by CodeRabbit

  • New Features

    • Export resume decisions now account for key export settings, including subtitle options, audio adjustments, subtitle source, container, and video encoder.
    • Export records retain the settings needed to validate whether a previous export can safely resume.
    • Subtitle format requests now distinguish between unspecified, empty, and explicitly selected formats.
  • Bug Fixes

    • Prevented exports from incorrectly resuming when relevant export settings have changed.
    • Preserved resume compatibility for older export records without the new settings data.

CaptureExecutionSnapshot omitted the newer DubbingSessionOptions flags
(ApplyTimbrePolish, RestoreOriginalPan, MatchOriginalLoudness,
BurnInSubtitles, SubtitleSource, SubtitleFormats, VideoEncoder), so a
cached export was resumed even when those flags changed, silently
ignoring user intent without --force-rerun.

Record normalized snapshot keys for each flag: booleans via ToString(),
SubtitleSource via ResolveSubtitleSource (null and translated match),
SubtitleFormats mapped directly so null/empty/[srt] are distinct and
case-insensitive, and VideoEncoder via VideoEncoderPreferenceSettings.ToKey.
Expose CaptureExecutionSnapshot as internal static (with SDK re-exposure)
and add covering xUnit tests.

Also pin dotnet 10.0.401 in mise.toml to fix Roslyn analyzer mismatch.
… manifest

FEAT-002 captured the export gating flags into the execution snapshot but
nothing on the Export resume path read them, so flipping ApplyTimbrePolish,
RestoreOriginalPan, MatchOriginalLoudness, BurnInSubtitles, SubtitleSource,
SubtitleFormats, VideoEncoder, or ExportFormat still resumed the stale export.

Persist the prior run's gating flags on the per-run ExportManifest and compare
them at resume time. A new ExportResumeGating helper is the single source of
truth for the canonical gating key/value set; both CaptureExecutionSnapshot and
the manifest-writing path use it so capture and comparison cannot drift.
StageArtifactResumeEvaluator.CanResumeStageAsync reads the manifest and refuses
to resume when any gating flag differs. Older manifests without gating fall back
to the existing resume behavior. Adds resume-path tests that fail if reverted.
…lt-path spurious reruns

The snapshot side emitted SubtitleFormatsTokenFromRawOptions(null) => "default"
while the manifest side persisted the resolved [Srt] token => "Srt" for the same
default-subtitle run, so every unchanged default export refused to resume.

Carry the raw requested formats through ExportStageRequest.RawSubtitleFormats and
have BuildManifest produce its token via SubtitleFormatsTokenFromRawOptions, so both
sides normalize identically (null => "default") and agree on the default path while
still diverging for genuinely different requests. Removed the now-unused
SubtitleFormatsTokenFromResolvedFormats producer. Added default-path resume tests.

📝 Walkthrough

Walkthrough

The export pipeline now records normalized export settings in execution snapshots and manifests. Export artifact resumption compares these settings asynchronously. Raw subtitle format distinctions remain available for gating. Tests cover matching, mismatching, compatibility, and snapshot normalization.

Merge Risk: 🟡 Moderate · up to 6438d

This change adds logic to avoid reusing a previously exported file when audio, subtitle, or encoder settings have changed. However, in edge cases where the previous export's saved settings file is missing, unreadable, or incomplete, the system currently falls back to reusing the old export anyway instead of safely re-running it, which can silently ship output that doesn't match the requested settings. This narrow-but-real gap should be tightened before merging, though it does not block the common path where settings are recorded normally.

The changes correctly address the issue where export resume was not respecting audio/subtitle/encoder flag changes. The implementation is well-designed with a centralized ExportResumeGating helper as the single source of truth, proper backward compatibility through nullable gating fields, and the fix for the default-path subtitle format divergence. The code is thoroughly tested and follows good engineering practices. No blocking defects identified.

  • The new resume tests seed ExportManifestGating directly, so they never exercise BuildExportGating(request) or the RawSubtitleFormats value passed through the pipeline. A regression in this persistence/wiring seam would leave all added tests green while storing the wrong gating flags and reintroducing stale export resumes. Add an ExportStageHandler test that runs ExportAsync with non-default flags/raw formats and asserts the persisted manifest.Gating.Flags.

  • This fixture injects Gating directly into a hand-built manifest, so it never exercises ExportStageHandler.BuildExportGating or the pipeline's RawSubtitleFormats forwarding. Removing either production wiring would still leave these resume tests green while newly written manifests omit or misrecord the flags. Add a handler/pipeline test that performs an export, reads its manifest, and then evaluates resume for the null, empty, and explicit format cases.

  • src/Trackdub.Application/Transcripts/FutureStageContracts.cs leaves the new parameter null when the desktop path invokes ExportStageRequestBuilder.TryBuild from ExportMixViewModel, risking incorrect export-stage behavior; ensure the desktop request supplies the parameter or explicitly handles the null case.
  • tests/Trackdub.Application.Tests/ExportResumeGatingTests.cs has maintainability and coverage concerns: a private helper duplicates production subtitle mapping, the “pins the v2 fix” comment does not match the shown manifest/snapshot values, and four helpers repeat the same eight-argument builder call; align the fixtures and centralize shared setup so these tests validate the intended behavior reliably.

Reject resume when the manifest gating data cannot be verified.

These branches return true for an unreadable, missing, empty, or partial gating payload. If an export setting changed, the pipeline can reuse a stale export without detecting the mismatch.

Return true only when a successfully deserialized legacy manifest has Gating == null. Return false for read failures, null manifests, empty flags, and missing required keys. Add tests for these failure paths.

Proposed fix
         catch (Exception ex) when (ex is IOException or UnauthorizedAccessException or System.Text.Json.JsonException)
         {
-            // A manifest that cannot be read tells us nothing about the prior run's flags.
-            // Preserve existing behavior (resume) rather than force a spurious rerun.
-            return true;
+            return false;
         }
 
-        IReadOnlyDictionary<string, string>? persistedFlags = manifest?.Gating?.Flags;
-        if (persistedFlags is null || persistedFlags.Count == 0)
+        if (manifest is null)
+        {
+            return false;
+        }
+
+        if (manifest.Gating is null)
         {
-            // Older projects have no persisted gating flags. There is nothing to compare against,
-            // so preserve the pre-existing resume behavior rather than force a spurious rerun.
             return true;
         }
 
+        IReadOnlyDictionary<string, string> persistedFlags = manifest.Gating.Flags;
+        if (persistedFlags.Count == 0)
+        {

         foreach (string key in ExportResumeGating.GatingKeys)
         {
             if (!persistedFlags.TryGetValue(key, out string? persistedValue))
             {
-                // Flag absent from the persisted set: the prior run did not record it, so we
-                // cannot prove a change. Skip it rather than force a rerun.

lines 242 - 246, Update the manifest evaluation logic in the resume evaluator
and its exception-handling branches so resume is allowed only for a successfully
deserialized legacy manifest whose Gating value is null. Return false for read
or deserialization failures, null manifests, empty flags, and manifests missing
required gating keys, while preserving true only for the explicitly valid legacy
case; add tests covering each failure path.

I'll address the review feedback with the following changes:

Changes to implement:
• Replace Path.Combine("exports", "dubbed.mp4") with explicit relative path literal "exports/dubbed.mp4" at tests/Trackdub.Application.Tests/ExportResumeGatingTests.cs:340
• Replace Path.Combine with Path.Join in TempDir constructor at tests/Trackdub.Application.Tests/ExportResumeGatingTests.cs:414
• Add logging to empty catch blocks in TempDir.Dispose() at tests/Trackdub.Application.Tests/ExportResumeGatingTests.cs:422-430
• Add InvalidDataException to the exception filter in ExportGatingMatchesSnapshotAsync at src/Trackdub.Application/Transcripts/StageArtifactResumeEvaluator.cs:242
• Replace test helper ExportResumeGating_ResolveSubtitleSource with call to production method ExportStageRequestBuilder.ResolveSubtitleSource at tests/Trackdub.Application.Tests/ExportResumeGatingTests.cs:214-220
• Add .Distinct(StringComparer.Ordinal) to deduplicate subtitle formats in SubtitleFormatsTokenFromRawOptions at src/Trackdub.Application/Transcripts/ExportResumeGating.cs:82

✅ All review feedback has been addressed and committed:

Changes implemented:

  • Replaced Path.Combine("exports", "dubbed.mp4") with explicit relative path literal "exports/dubbed.mp4" in tests (line 340)
  • Replaced Path.Combine with Path.Join in TempDir constructor to avoid silent path segment drops (line 414)
  • Added InvalidDataException to exception filter in ExportGatingMatchesSnapshotAsync to catch wrapped JSON exceptions from FileSystemArtifactStore (line 242)
  • Replaced test helper ExportResumeGating_ResolveSubtitleSource with delegation to production method ExportStageRequestBuilder.ResolveSubtitleSource (line 214)
  • Added .Distinct(StringComparer.Ordinal) to deduplicate subtitle formats in SubtitleFormatsTokenFromRawOptions (line 82)

Note: The empty catch blocks in TempDir.Dispose() already have proper logging via System.Diagnostics.Trace.WriteLine, so no changes were needed there.

/q dev Update the doc comment on line 74 to reflect that duplicates are collapsed: change "Order and duplicates are preserved" to "Order is preserved and duplicates are collapsed" or similar wording that matches the .Distinct() implementation

I'll update the documentation comment to reflect that duplicates are collapsed while order is preserved.

Changes to implement:
• src/Trackdub.Application/Transcripts/ExportResumeGating.cs:74-75 - Update the doc comment to state "Order is preserved and duplicates are collapsed" instead of "Order and duplicates are preserved" to match the .Distinct() implementation on line 82

✅ Documentation update complete. The doc comment now accurately reflects that duplicates are collapsed while order is preserved, matching the implementation that uses .Distinct(StringComparer.Ordinal) on line 82.

The SubtitleFormatsTokenFromRawOptions method uses .Distinct() to remove duplicates, but the documentation comment incorrectly stated that duplicates are preserved. Updated the comment to accurately reflect that order is preserved and duplicates are collapsed.
