Final-review fixes: the Dockerfile dep layer now installs boto3 (pyproject declares it; pip install --no-deps skipped it), and build_index stamps "timezone": "UTC" so the frontend can't misread frame stamps — this project has shipped two tz bugs at exactly this seam.

Phase 2b of the Weather app (#184): the radar mirror. All 1,152 five-minute NEXRAD CONUS composite frames for 2001-09-09..12 are now on Wasabi under
weather/radar/— zero gaps in the IEM archive for our window (Hurricane Erin included).What's in here
weather_recon/radar.py— pure helpers: 5-min frame-stamp enumeration, IEM archive URLs, ESRI world-file → MapLibre corner geometry ([[-126,50],[-66,50],[-66,24],[-126,24]] verified), PNG dimension reads, index builder.weather_recon/wasabi.py— slim uploader with video-grabber's proven Wasabi client settings (SigV4, path addressing, when_required checksums).weather_recon/flow_radar.py—load-weather-radar: download-with-cache → per-frame geometry verification (hard error on mismatch) → upload-if-absent (resumable via onelist_objectssweep) →weather/radar/index.json(bounds, frame list, gaps,"timezone": "UTC", key pattern — the frontend reads the pattern instead of hardcoding).Verification
image/png+max-age=31536000, index bounds exact; sample frame 6000×2600 px / 114 KB. Resumability proven twice for real — two mid-run kills resumed cleanly withskip_existing(85-frame tail completed on the final resume, then a full re-run uploaded 0).Follow-ups
weather/prefix needs a file-proxy allow-list entry (Traefik Ingress path rule in the infra repo) before the frontend can fetch frames via files.911realtime.org.🤖 Generated with Claude Code
