# Timepoll Implementation

- [x] Poll model, SQLite persistence, timezone-aware schedules and vote conversion.
- [x] Public/admin API, edit conflicts, live updates and basic abuse limits.
- [x] Poll creation, administration, voting grid and overlap summaries.
- [x] Responsive light/dark UI, touch interactions and accessibility.
- [x] Backend and browser tests, Docker image definition, build workflow and documentation.

Public codes use nine Crockford Base32 characters (3-3-3); private admin
codes use twelve (4-4-4). Participant editing is intentionally trust-based.
There are no accounts, calendar integrations, notifications or meeting durations.
All persisted voting intervals are UTC instants; IANA timezones control display
and conversion of the creator's local daily schedule.

## Verification

- 24 backend tests pass, including DST transitions, half-hour transitions,
  vote conversion, edit conflicts, code collisions and restart persistence.
- Chromium desktop and touch/mobile tests pass in light/dark modes, including
  live updates and a 320-pixel-wide editing viewport.
- Ruff, workflow/Compose YAML validation and whitespace checks pass.
- The build workflow runs the backend tests before building and publishing the
  Docker image. Publishing an image does not deploy a running service.

## Usability Follow-Up

- [x] Explicit added-date collection and pending-date validation.
- [x] Matching time dropdowns and outward rounding on slot-size changes.
- [x] Root-level public/private links; old preview routes removed.
- [x] Direct clipboard copying, tested against the actual clipboard over HTTP.
- [x] Dismiss hover details on pointer exit and page/grid scrolling.
- [x] Other participants' availability and boundaries remain visible through draft selections; combined view after saving or cancelling.
- [x] Compact 15-minute rows on desktop and mobile.
- [x] Emphasized hour labels and rules for 15- and 30-minute grids.
