🎯 What: The testing gap addressed
The cleanJsonResponse function in extension/background/parser-helper.js was previously missing explicit tests, leaving a gap in coverage for LLM response parsing logic.

📊 Coverage: What scenarios are now tested

  • Plain JSON objects and arrays
  • Markdown-fenced JSON (```json format)
  • Generic Markdown-fenced JSON (``` format)
  • JSON wrapped in leading/trailing whitespace
  • Invalid JSON handling (verifying SyntaxError throws)

✨ Result: The improvement in test coverage
The test suite now explicitly validates the string sanitization and JSON parsing logic for this critical utility function. The tests execute consistently as part of the overall Chrome Extension test runner.

These PRs targeted parser-helper.cjs, test-service-worker.js and
test-extractor.js, all of which this branch removed, so they cannot
merge. Their cases that add coverage now live in the ESM suites:

- test-parser-helper.mjs: JSON arrays, whitespace with no fence, and a
  SyntaxError for a trailing comma, truncated JSON, or plain text (#99, #101).
- test-course-context.mjs: null and non-URL input, a #fragment on a
  course root, a non-Canvas path, and a missing or non-numeric
  course id (#100).

#108's one real fix, `cut` in test-doctor's mock PATH, already reached
this branch from main.

Duplicate of #101, and it tests parser-helper.cjs, which #109 deletes. The cases that added coverage (JSON arrays, whitespace with no fence, and SyntaxError on malformed input) are ported into test/test-parser-helper.mjs in 36e5919. Thanks.

Closing as part of triaging the open PRs against #109, which restructures the extension (it removes the .cjs twins, renames test/test-*.js to .mjs, and rewrites the crawler and side panel). It is up to date with main as of ee79db2.
