📝 WalkthroughWalkthroughThe change adds user availability retrieval and local-time conversion. It adds a dedicated availability route and back navigation. Availability sheets can constrain selectable cells and link to editing. Chat proposals now use overlapping availability and confirmed-meeting state. ChangesAvailability flow

Block selection of unavailable cells.
These lines only render unavailable cells. The proposal pointer handler still calls onProposalSelected for a grey cell. A user can enable Propose and submit a time outside the overlap. Before setting selectionStartProposal, reject a cell whose unavailableGrid value is true.

Match availability by complete date.
availableAvailabilities contains slots for all pager pages. mapToGrid compares only LocalDate.day at AvailabilityUtil.kt, Line 84. For example, an available October 5 slot makes September 5 appear available. Compare dates with date.toLocalDate() instead.
Proposed fix
- val column = dates.indexOfFirst { it.day == date.day }
+ val column = dates.indexOf(date.toLocalDate())🤖 Prompt for AI Agents

Fail closed when availability cannot be loaded. onSendAvailabilityPressed converts a missing current-user ID or an availability-fetch exception to overlapTimes = null. The availability sheet treats null as “the greying feature isn't used,” so proposal mode can select any displayed grid cell and send it to onMeetingProposal without an overlap check. Handle this failure before showBottomSheet by showing an error or disabling proposing. A missing peer ID is not established because otherUserId is a non-null route value.

Overview
Changed how availability is handled to reach parity with released iOS version. Fixed some minor issues relating to meeting proposal system.
Changes Made
Test Coverage
Tested on Medium Phone, was not able to test if proposal slots will be not greyed out if both people mark availabilities. Will test when in-person with another dev.
Next Steps (delete if not applicable)
Change "Send Availability" button to be a clickable icon in the top right. Small change, can wait till after release.
