Guest Timezone Display #7
Conversation
Changes SummaryThis PR adds a guest timezone display feature to the booking details sheet that shows meeting times in the attendee's local timezone when it differs from the host's timezone. It includes a new GuestTimezoneDisplay component with basic test coverage and adds moment-timezone as a dependency. Type: feature Components Affected: BookingDetailsSheet, WhenSection, GuestTimezoneDisplay Files Changed
Architecture Impact
Risk Areas: Using loose equality (==) instead of strict equality (===) for timezone and numeric comparisons, Console.log debug statement left in production code, Unused state variable isExpanded defined but not utilized, Multiple redundant calculations (formatted_start_12h, formatted_start_24h computed but never used), Weak TypeScript typing with 'any' types for component props, Test file contains only shallow assertions that don't actually test component behavior, Using 'var' instead of 'const'/'let' for dayDiff variable, Inline styles mixed with Tailwind classes (anti-pattern), Potential timezone calculation edge cases around year boundaries, No validation for invalid timezone inputs despite checking isValidTz variable that's never used Suggestions

🟠 HIGH - Console.log statement in production code
Agent: accessibility
Category: quality
Description:
A console.log statement in GuestTimezoneDisplay will execute in production, exposing debug data and cluttering browser console.
Suggestion:
Remove the console.log statement entirely or wrap in development-only conditional: if (process.env.NODE_ENV === 'development') { console.log(...); }

🟠 HIGH - Missing dependencies in useMemo
Agent: bugs
Category: bug
Description:
useMemo calculates values using guest_timezone and host_timezone but only includes start_time in dependencies, causing stale values when timezones change.
Suggestion:
Add guest_timezone and host_timezone to the dependency array: [start_time, guest_timezone, host_timezone]

🟡 MEDIUM - Unsafe type assertion with 'any' type
Agent: react
Category: quality
Description:
Parameters start_time and end_time are typed as 'any', bypassing TypeScript type checking where string | Date | dayjs.Dayjs would be appropriate.
Suggestion:
Replace 'any' with specific types: start_time: string | Date, end_time: string | Date

🟡 MEDIUM - Unsafe 'as any' type assertion
Agent: react
Category: quality
Description:
The attendees property is cast to 'any', bypassing type checking when WhenSection expects Array<{ timeZone: string; name: string; email: string }>.

Remove 'as any' and properly type the booking.attendees or update the BookingOutput type definition

🟡 MEDIUM - Test contains conditionals instead of testing component behavior
Agent: testing
Category: quality
Description:
This test contains an if statement that reimplements logic rather than testing component output. The test will always pass because it only tests local variables.
Suggestion:
Remove the conditional logic and test actual component behavior, or remove this test entirely.
Why this matters: Conditionals in tests hide failure cases and make tests harder to debug.

🟠 HIGH - Test file for non-existent component
Agent: testing
Category: quality
Description:
The entire test file is testing a component (GuestTimezoneDisplay) that doesn't exist in the codebase. All 7 tests pass without testing any actual behavior - they only verify primitive values.
Suggestion:
Either create the GuestTimezoneDisplay component and write proper tests that render it, or remove this test file entirely. The imports for render and screen are never used.
Why this matters: New parameters without tests are a regression risk and indicate incomplete PR.

While not technically nested inside another component, the pattern and the isExpanded state that's never used to conditionally render content is problematic. Suggestion: The component is at file scope which is correct, but the useState for isExpanded is never used - the component never conditionally renders based on isExpanded state.
