Warning

Review limit reached

@don-petry, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 42 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Code Review

This pull request refactors multiple components by extracting inline logic into modular helper functions. In deploy/index.html, project resolution and error HTML building are extracted. In src/calendar-to-sheets/src/index.js, row upserting, insertion, and deletion computation are modularized. In src/gmail-to-drive-by-labels/src/index.js, duplicate attachment checks, file name resolution, and document rebuilding phases are extracted into separate helpers. The review feedback highlights two key improvement opportunities: optimizing moveEmailsPhase by avoiding redundant and expensive Google Apps Script API calls to processedLabel.getThreads() and replacing array mutations with simple index tracking, and safely handling null or undefined error objects in buildDeployErrorHtml to prevent potential runtime TypeError crashes.

CI Failure: SonarCloud Code Analysis

Step: Quality Gate (New Code Coverage)
Root cause: Test failure

The SonarCloud Quality Gate failed because New Code Coverage is 0.0%, below the required 80% threshold. This PR (branch dev-lead/issue-427-20260707-1917) modifies src/gmail-to-drive-by-labels/src/index.js and src/calendar-to-sheets/src/index.js without adding any corresponding tests, so none of the changed lines are exercised by the test suite. SonarCloud also flagged 3 minor code-smell warnings (an unused Session variable assignment/declaration in gmail-to-drive-by-labels/src/index.js:167, and a preference for Number.isNaN over isNaN in calendar-to-sheets/src/index.js:190), but these are warnings, not the blocking condition.

Suggested fix: Add unit tests covering the new/changed logic in src/gmail-to-drive-by-labels/src/index.js and src/calendar-to-sheets/src/index.js to bring new-code coverage to at least 80%, and remove the unused Session variable while switching to Number.isNaN.

Pull request overview

Refactors several high-complexity routines flagged by SonarCloud (S3776) into smaller helper functions, aiming to reduce cognitive complexity while preserving existing behavior across Apps Script logic and the deploy UI.

Changes:

• gmail-to-drive-by-labels: extracted attachment dedupe + name-conflict logic into helpers; extracted rebuild state machine phases into helpers.
• calendar-to-sheets: extracted upsert/insert/delete decision logic into helpers to simplify syncCalendarToSheet.
• deploy/index.html: extracted idempotent project resolution and deployment error rendering into helper functions.

CI Failure: SonarCloud Code Analysis

Step: Quality Gate
Root cause: Test failure (missing coverage)

SonarCloud's Quality Gate failed because New Code coverage is 0.0%, well below the required 80% threshold. The PR extracts several new functions with no accompanying tests: resolveDeployProjectId and buildDeployErrorHtml in deploy/index.html, and upsertRows, insertNewRows, shouldDeleteRow, computeRowsToDelete in src/calendar-to-sheets/src/index.js. Since none of these lines are exercised by the existing test suite, SonarCloud counts 0% coverage on all new code.

Suggested fix: Add unit tests for the six newly extracted functions listed above (e.g. upsertRows/insertNewRows/shouldDeleteRow/computeRowsToDelete in the calendar-to-sheets test suite) so the new code paths are exercised and coverage crosses 80%.

CI Failure: SonarCloud Code Analysis

Step: Quality Gate — new_coverage condition
Root cause: Test failure

The SonarCloud Quality Gate failed because coverage on new code is 0.0%, versus the required minimum of 80% (115 new lines added, all 115 uncovered). This PR (issue #427) extracts two new functions in deploy/index.html — resolveDeployProjectId() and buildDeployErrorHtml() — out of an inline handler to reduce cognitive complexity (S3776), but no tests were added to exercise either function, so none of the new lines are covered by the test suite. All other gate conditions (reliability, security, maintainability, duplication, security hotspots) pass.

Suggested fix: Add unit tests for resolveDeployProjectId() (covering the stored-id-hit, stored-id-404-fallback, and create-new-project paths) and buildDeployErrorHtml() (covering the API-disabled and generic-error branches) in deploy/index.html, then re-run the analysis to confirm new-code coverage clears the 80% threshold.
