v1.0.0 — first stable release

[1.0.0] — 2026-06-14

First stable release: a complete drone video → gaussian-splat pipeline. The headline of the 1.0 cycle was replacing a non-functional gsplat hook with a real in-process trainer, validated end-to-end on GPU hardware (PSNR 27.5 / SSIM 0.79 on a full-preset run).

Added

• CLI geotagger (drone-video-geotagger): extracts DJI SRT telemetry from MP4 with ffmpeg, interpolates per-frame GPS positions, writes EXIF via ExifTool, produces an audit CSV. WSL-aware path handling.
• FastAPI backend: session import with quality scoring (sharpness/brightness), DJI XMP parsing (relative altitude, yaw, gimbal pitch), ground-footprint geometry (UTM/Shapely), coverage analysis, lawnmower mission planning with KML/GPX export, flight-log sync, session log, storage management, and system resource reporting — ~53 endpoints across 17 routers, self-documented at /docs.
• Reconstruction pipeline: COLMAP SfM orchestration (quick/full presets, target-area crop, manual frame selection), GPS geo-registration (COLMAP↔UTM similarity transform), per-frame reprojection-error reporting, background job management with progress/cancel.
• React frontend (11 tabs): Map, GPS Sync, Review, Plan, Export, Session Log, Reconstruct, Jobs, Storage, Splat Viewer (3D canvas, PSNR/SSIM sparklines, coverage-gap heatmap, GPS annotations, distance/area measurement, ortho/3D split view, flythrough recording), and Compare (voxel change detection between flights).
• Exports: WebODM package, GeoJSON, LAS 1.4 point cloud with UTM CRS, optional SuGaR mesh (GLB/OBJ/MTL with geo-reference sidecar), browser-recorded or server-rendered flythrough video.
• Documentation suite: a user manual, end-to-end workflow tutorial, install guide, GPU setup, troubleshooting, and architecture overview.

Added (real reconstruction — the 1.0 headline)

• In-process gaussian-splat trainer on gsplat.rasterization, replacing the phantom gsplat.train API that made splat training impossible. Sparse-cloud initialization, per-attribute Adam, DefaultStrategy densification with a VRAM-aware max-gaussian cap, pure-torch SSIM loss, SH-degree warmup, and INRIA-layout PLY export. New stdlib+numpy modules colmap_io (sparse-model loader) and ply_io (3DGS PLY read/write/prune) underpin it; none of torch/gsplat are required to import the backend.
• GPU thumbnail and server-side flythrough renderers (best-effort; browser recording remains the primary flythrough path).
• Backend startup preflight: a missing COLMAP binary logs a warning at launch, and /system/resources reports colmap_available / gsplat_available.
• GPU install guide (docs/SETUP.md) verified on Windows / CUDA 13.2 / RTX 3050 Ti, including the torch/gsplat version pins and build workarounds.

Changed

• Version bumped to 1.0.0 across the package, API, and frontend; classifier set to Production/Stable.
• The reconstruction extra no longer pins gsplat (no resolvable CUDA wheel exists); GPU training is a documented manual install.
• CLI frame index is now read from the last number in a filename, so prefixed names like DJI_0081_frame_42.jpg time correctly.
• CI runs a Python 3.10/3.11/3.12 matrix plus a frontend lint/test/build job.

Removed

• Docker configuration (docker-compose.yml referenced Dockerfiles that never existed); native install only for 1.0.

Fixed

• Mid-training cancellation now marks the job failed instead of mislabeling it a successful colmap_only completion.
• All datetime.utcnow() deprecation warnings (Python 3.12+) eliminated.
• Splat viewer no longer hangs on load where SharedArrayBuffer is unavailable.
• dev.sh / dev.bat repaired for the pyproject-extras layout.

Fixed (1.0 hardening, from the 2026-06-05 real-data walkthrough)

• Footprints were sized from absolute (ASL) altitude instead of height above ground, inflating them ~4×; DJI XMP RelativeAltitude is now used (#98).
• Footprints ignored drone heading; yaw is now read from DJI XMP and applied (#98).
• Image import double-counted every file on case-insensitive filesystems (#101).
• Import progress polling stopped permanently when the first poll returned pending (#94).
• Import modal asked for an absolute path the backend (correctly) rejects; it now asks for a path relative to imports/ (#95).
• Session Log rendered "Invalid Date" (#96).
• Plan exports landed in backend/exports/ instead of the configured ./exports (#97).
• Export tab layout was right-shifted (#102); Storage "Data" category measured the entire data directory instead of the database and config (#100).
• Reconstruction jobs crashed outright when gsplat was absent; they now complete with the COLMAP sparse cloud (colmap_only) and clear guidance (#99). (With gsplat installed, real splat training now runs — see "real reconstruction" above.)
• CodeQL path-injection findings hardened across import, export, and storage endpoints.

Security

• All external tools (ffmpeg, exiftool, COLMAP) invoked as argv lists — no shell.
• Import/export/storage paths validated against traversal; imports constrained under imports/.
