When the induction loop proposes a new vocabulary term, it now records
which sampled call(s) most likely produced the suggestion. Admins see
a collapsible "▶ source" player under each pending term showing the
audio clip and transcript, so they can hear what was actually said
before approving or dismissing.
- vocabulary_learner: track sampled call docs, attach source_call_ids
to each pending term via word-overlap search with fallback
- types: VocabularyPendingTerm.source_call_ids?: string[]
- c2api: add getCall(id) using existing GET /calls/{call_id} endpoint
- VocabularyPanel: SourceCallPlayer component — lazy-loads call on
first expand, shows audio controls + transcript snippet
Map (MapView.tsx):
- Fan/hand-of-cards marker clustering: groups nearby markers by pixel
proximity (union-find), renders as rotated color cards showing all types
- Pulsing ring CSS animation on recording nodes (pulse-ring keyframe)
- Live incident overlay panel — right sidebar (desktop) / bottom drawer (mobile),
clickable to flyTo incident location
- Auto-fit button (⤢) fits all markers in view with fitBounds
- "Live · Xs ago" timestamp badge (refreshes every 10s)
- Weather Radar layer (NEXRAD via Iowa Env Mesonet, no API key)
- ADS-B + Meshtastic placeholder layers (off by default)
Map page (map/page.tsx):
- Fullscreen / kiosk toggle: fixed z-50 overlay covers nav, map fills viewport
- lastUpdated tracking passed to MapView for Live timestamp
Systems page (systems/page.tsx):
- Duplicate System button: opens form pre-filled with Copy of <name>
- RadioReference HTML import: file upload → DOMParser validates .rrlblue
structure, parses talkgroup categories, modal lets user select which
categories to import, auto-maps RR tags to local tags (law→police, etc.)
