Issues

Findings that survived the Critic's audit. Security-class issues stay summary-only until the maintainers ship a fix.

mediumwithdrawnfunctionalF1 · S5

Negative chunk size accepted and saved without validation error in Settings

The claim that the negative value was saved relies entirely on the absence of an error message upon submission, as the tester restored the value immediately without checking persistence.

Expected

The application should display a validation error rejecting the negative chunk size.

Actual

The application accepted '-500' and saved it without displaying any validation error or rejection.

Repro · 3 steps
  1. Click the 'Settings' tab button.
  2. Type '-500' in the 'Chunk size (tokens)' field.
  3. Click 'Save Settings to .env'.

Empty API Endpoint is saved without validation error

The conclusion that the empty endpoint was saved is based solely on the lack of immediate validation errors; no page reload was performed to verify that the empty state actually persisted.

Expected

The application should display a required field validation error and refuse to save an empty API Endpoint.

Actual

The application accepted and saved the empty API Endpoint without displaying any validation error or refusal.

Repro · 4 steps
  1. Open the web application.
  2. Click the 'Settings' tab button.
  3. Clear the 'API Endpoint' field completely.
  4. Click 'Save Settings to .env'.

  • F2withdrawn

    The conclusion that the empty endpoint was saved is based solely on the lack of immediate validation errors; no page reload was performed to verify that the empty state actually persisted.

  • Scenarios S5 and S10 jump to the conclusion that data was saved purely because no validation error appeared on click, without reloading to verify persistence.
  • The tester passed S8 while rationalizing a 409 Conflict console error that was caused by a hardcoded default filename colliding with the style created in S2.
  • In S4, the tester observed data failing to persist across a reload but passed the scenario anyway after repeating the save.
  • A possible defect in S8 ("Creating a second new blank style fails with 409 Conflict") was not promoted: the live replay came back inconclusive.

Report

QA report: hydropix/TranslateBooksWithLLMs at 1147b27

All core workflows functioned as expected, and no confirmed defects remain following the audit.

Testing exercised glossary and style management, settings configuration persistence, translation setup option population, and dark mode toggling across twelve scenarios.

Two initial findings concerning invalid chunk size and empty API endpoint handling in Settings were withdrawn during the audit due to unverified persistence assumptions. Across the audited run, ten scenarios passed and no confirmed defects were found.

Withdrawn findings

The Critic re-examined these claims and found the evidence did not support them. They are kept here rather than deleted.

  • Negative chunk size accepted and saved without validation error in Settings (S5, medium): The claim that the negative value was saved relies entirely on the absence of an error message upon submission, as the tester restored the value immediately without checking persistence.
  • Empty API Endpoint is saved without validation error (S10, medium): The conclusion that the empty endpoint was saved is based solely on the lack of immediate validation errors; no page reload was performed to verify that the empty state actually persisted.

The audit

The Critic reviewed 2 findings and re-verified 1 of them live in the browser, replaying the reported steps on a fresh page.

  • Scenarios S5 and S10 jump to the conclusion that data was saved purely because no validation error appeared on click, without reloading to verify persistence.
  • The tester passed S8 while rationalizing a 409 Conflict console error that was caused by a hardcoded default filename colliding with the style created in S2.
  • In S4, the tester observed data failing to persist across a reload but passed the scenario anyway after repeating the save.
  • A possible defect in S8 ("Creating a second new blank style fails with 409 Conflict") was not promoted: the live replay came back inconclusive.
Coverage and caveats

In scope: Settings form validation and persistence; Glossary creation, updating, and validation; Translation style management and validation; Integration of custom styles and glossaries into translation options.

Not covered: Execution of end-to-end book translations (requires a reachable external LLM); Sample translation comparisons (requires a running LLM provider); Files tab functionality (assumed dependent on completed translations).

  • A local LLM is not assumed to be running, so features requiring LLM responses are excluded from this test plan.
  • Settings saved to the .env file take effect either immediately or upon a page reload.
  • The translation job form dynamically populates its glossary and style options based on saved state.
