Drift Analysis

v2.3 current

First production deploy on Cloudflare (Workers + D1 + Pages) under the drift-analysis project.

v2.2 superseded

Renamed — product is now called Drift Analysis (dashboard + management). The hardware platform itself is still DriftSpawn.

v2.1 superseded

Full fleet management system on Cloudflare Workers + D1 + Pages
New Fleet tab: sortable/filterable table, add/edit drifters, deployment workflow, recovery workflow (R variants auto-route to workshop with cycle count, E variants to retired), maintenance log per unit
Bearer-token auth, CORS-friendly, same-origin routing supported
Deploy script with backup-before-migrate pattern

v2.0 superseded

Sponsor colouring — drifters tagged with a sponsor (e.g. RRF, SSC, CWI); trails and start-rings take the sponsor's colour while marker fill keeps the mode colour and shape keeps the variant
Smooth continuous zoom interpolation — fractional zoom + per-frame lerp, no more discrete zoom-level jumps
14-day deployment scenario — extended from 36 h; four drifters beach or run aground (Yarrabah, Cape Grafton, outer reef, Little Fitzroy), one stays offshore drifting east into the Coral Sea
Cadence transitions baked into the data — HIGH_CADENCE 15 min (first 48 h) → NORMAL 60 min while drifting → BEACHED 30 min once stationary, per v1.3 firmware spec
Embedded coast outlines for Fitzroy, Little Fitzroy, Cape Grafton/Yarrabah mainland, and an outer GBR reef — always visible without map tiles
Realistic spawn-night ring deployment around Fitzroy
Label collision avoidance — outward from deploy point, min 20° angular gap, iterative push-out
Solid drift trails (replaced fading gradient)
Five playback speeds (Very Slow / Slow / Normal / Fast / Very Fast)
View All toggle — auto-fit map to all visible drifters; starts close, zooms out as they spread
Video export — render the drift to a downloadable MP4 / WebM at the selected speed, with the same auto-zoom behaviour
Layer toggle for Map (OSM) and Satellite (Esri) tiles when available

v1.9 superseded

v1.8 superseded
