  • Removed the language prefix from displayed model configuration information.
  • Skipped optional metrics containing NaN values.
  • Added a warning when box plot values exceed the configured display limits.

PR Type

  • New Feature
  • Bugfix

Summary by CodeRabbit

  • New Features

    • Report sidebars now provide independently scrollable navigation with improved spacing, benchmark markers, and automatic tracking of the active section.
    • Navigation automatically adjusts to window size and keeps the active link visible.
  • Bug Fixes

    • Box plots are replaced with a clear unavailable message when metric values exceed configured display limits.
    • Missing or undefined metric values are handled more reliably.
    • Benchmark language information is now reflected in configuration labels.

Review Change Stack

Walkthrough

The report models now handle missing metrics and benchmark metadata. Box plots can display unavailable states. Audio and evaluation sidebars support bounded scrolling and improved navigation tracking. S3 clients accept a configurable signature version.

Changes

Report rendering

Layer / File(s) Summary
Metric data and plot availability
scripts/tts_comparison_report/reporting/models.py, scripts/tts_comparison_report/reporting/components/boxplots.py
Metric values of None or NaN return as None. Bucket configuration includes benchmark language metadata. Box plots display an axis-free unavailable message when model means exceed configured limits.
Sidebar layout and navigation
scripts/tts_comparison_report/templates/audio_report.jinja, scripts/tts_comparison_report/templates/eval_report.jinja
Sidebars use dynamic bounded scrolling and hidden scrollbars. Benchmark links wrap and show a marker. Navigation preserves clicked-link state and scrolls active links into view when appropriate.

S3 client configuration

Layer / File(s) Summary
S3 client options
scripts/tts_comparison_report/reporting/s3_client.py
S3Config adds signature_version. S3Client passes it with connect_timeout to botocore Config.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 6ee93

The update changes presigned URL signing while retaining one-year report links; if the configured storage backend does not support that signing and expiration combination, generated report URLs can fail. The PR also contains localized issues that may mislabel benchmark configurations or render invalid metric statistics, so it is not merge-ready until these bounded correctness risks are fixed or explicitly accepted.

Poem

I’m a rabbit with plots in my burrow,
Missing means now show what they borrow.
Sidebars scroll neat,
Links mark each beat,
And S3 signs requests without sorrow.

395-398: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Align the metrics type with the new null-value contract.

This code now accepts None for a metric value, but BenchmarkData.metrics at Line 155 is still typed as Optional[dict[str, float]]. Update the annotation to include optional metric values. Otherwise typed callers can treat a missing value as a float.

Proposed annotation update
-    metrics: Optional[dict[str, float]] = None
+    metrics: Optional[dict[str, Optional[float]]] = None

In `@scripts/tts_comparison_report/reporting/components/boxplots.py`:
- Around line 103-112: Update the boxplot preparation flow around
_validate_numeric_metric_value, _get_metric_stats, and prepare_boxplots to
exclude non-finite samples before computing range checks, means, confidence
intervals, and labels. Handle arrays emptied by filtering without plotting them
or producing NaN statistics, while preserving existing behavior for valid finite
samples.

In `@scripts/tts_comparison_report/reporting/models.py`:
- Around line 337-339: Update the configuration_str derivation near
BENCHMARK_META and suffix so it removes the language-aware suffix only when
dir_name ends with it; otherwise remove the benchmark-only _{name} suffix
accepted during directory discovery, preserving the full configuration prefix
such as config.

In `@scripts/tts_comparison_report/reporting/s3_client.py`:
- Line 29: Separate the S3 backend and signing configuration from the default
signature_version in the S3 client; configure AWS S3 and SigV4-only backends to
use “s3v4” with an expiration no greater than 604800 seconds, while retaining
“s3” only for a documented backend that supports one-year URLs. Update
generate_report.py integration paths and add tests covering both configurations.
