====== TIMI Changelog ======

===== 2026-04-27 =====

  * **Dataset Viewer & Agent Workflow** — Added Rerun-based ''dataset_viewer.py'' for browsing local and remote capture datasets with multi-mount support, sidecar normalization, timeline plots, and a web viewer on port 9090. Updated agent instructions for tmux window management (''runio'', ''tdash'', ''gopro'').
  * **GoPro Client Inline Merge** — Merged ''clients/gopro-scicam/'' from submodule into the main repository as inline history, simplifying builds and removing submodule sync friction.
  * **Tooling Suite** — Added ''tools/colmap_parser'' and ''tools/mirror_server'' alongside the dataset viewer.

===== 2026-04-26 =====

  * **Unified Sidecar Schema v1.5** — All capture sources (Android and GoPro) now emit the same JSON sidecar format. Renamed ''item_id'' to ''qr_item_id'', added ''device_name'', ''device_id'', and ''camera_file'' fields. Legacy v1 sidecars are preserved as-is.
  * **Discovery Protocol Extracted** — Moved UDP multicast beacon specification from ''AGENTS.md'' into ''references/discovery_protocol.md'' as a standalone reference document.
  * **Box QR Workflow** — Fullscreen borderless QR view on DP-1 for the GoPro client, per-capture UUID generation (capture_id), and gamepad "Next Box" button (Y) for rapid box cycling.
  * **Dashboard Enhancements** — Gallery and sidecar preview, capture_alert feedback, and beacon-based auto-discovery sync.

===== 2026-04-25 =====

  * **GoPro Station Mode** — Split-screen full-screen view: live preview alongside the last capture. Accessible via UI button or F key.
  * **QR Debounce & History** — Require two consecutive QR detections before accepting a new code to reduce flicker. Added ''/api/qr_history'' endpoint and prominent QR info panel.
  * **Real Camera Settings in Sidecars** — GoPro bridge now queries actual ISO, shutter speed, aperture, focal length, and AE/AWB lock state from the camera for accurate metadata.
  * **Lens Mode Toggle** — Switch between Wide and Linear lens modes via API and UI; persists in sidecar JSON.
  * **GoPro Deletion Fixes** — Corrected delete path format (removed erroneous ''DCIM/'' prefix), added bulk delete fallback, and robust ''Clear All'' flow.
  * **Background Sync & Duplicate Prevention** — Sync history tracks GoPro files across restarts so clearing local files does not trigger re-downloads.
  * **XInput / Gamepad API Support** — Xbox 360 controller mapped: A/X capture photo, Y advances box ID, B toggles QR overlay.
  * **GoPro Auto-Capture v2** — Structural change detection with motion threshold and settle-delay parameters; captures only when objects remain on the table (ignores passing hands).
  * **UI Polish** — Event log panel, QR flash overlay on detection, ROI visibility toggle, modal robustness, and JSON sidecar panel in gallery.

===== 2026-04-24 =====

  * **SciCam API-First Rewrite** — Fullscreen preview with IP overlay, NanoHTTPD REST API, removal of ZXing GUI hop.
  * **QR Auto-Capture** — BoofCV runs on preview frames; snaps automatically when a QR code is detected. Includes debug overlay, chime, and flash feedback.
  * **Client Submodules** — Added ''clients/go-scicam'' and ''clients/web-scicam'' as submodules.
  * **OpenAPI 3.0 Spec** — Formal API specification in ''api_spec.yaml''.
  * **Docker Build Support** — Cached Docker builds for the Android app with restored Gradle wrapper.
