Implements a scheduler that retunes the rig automatically when no SSE
clients are connected. Two modes are supported:
- Grayline: tunes to per-period bookmarks (dawn/day/dusk/night) based on
an inline NOAA solar algorithm given station lat/lon.
- Time Span: tunes to bookmarks within user-defined UTC windows; midnight-
spanning intervals supported.
Backend:
- SchedulerStore (PickleDB, sch:{rig_id} keys) in scheduler.rs
- spawn_scheduler_task polls every 30 s, checks context.sse_clients == 0,
sends SetFreq + SetMode via RigRequest with rig_id_override
- HTTP API: GET/PUT/DELETE /scheduler/{rig_id}, GET …/status
- sse_clients Arc<AtomicUsize> added to FrontendRuntimeContext and shared
with the SSE counter in build_server (single source of truth)
- /scheduler/ added to Read auth routes (write requires Control)
Frontend:
- Scheduler tab (clock icon, 6th position) with Grayline/TimeSpan UI
- scheduler.js plugin: loads config + bookmarks, live status polling
every 15 s, write controls hidden for Rx-role users
- CSS .sch-* component styles added to style.css
- SCHEDULER.md design document at repo root
