- Acq_ID supports leading zeros (text input + smart increment) (#903) - Sample_ID as string + save confirmation snackbar (#889-893) - Show project/sample/operator/gear in acquisition page (#894) - Add flowcell size (µm) to magnification button labels (#901)
- Compose fully-qualified project_sample_acq IDs in update_config (#882) - Space-to-underscore sanitization in IDs - Gallery + Explorer URL path sanitization for legacy TSVs
- Replace direct deleteItem with confirmDelete + dialog - Show acquisition and sample ID in confirmation prompt - Warning that deletion cannot be undone
- set object_datetime also persists lat/lon if present - set object_latlon also persists date/time if present
The start acquisition function read acq_nb_frame and acq_interframe_volume from Node-RED globals, but the globals were written by a parallel message path. When the user changed form values and clicked Start, the read happened before the write, causing the acquisition to use stale values. Fix: start acquisition now reads from msg.payload first (carried with the command), falling back to globals for backwards compatibility. handleAcqStatusChange explicitly passes acq values in the start message.
Replace full-file TSV loading with streaming columnar reader that extracts only the 24 columns used by charts. Memory usage drops from ~500MB to ~9MB for 56K-row datasets. Chart node improvements: - Scatter plots (heatmap, colorspace, aspect, greenness, complexity, texture) use reservoir sampling capped at 10K points - Histograms (ESD, solidity) pass all values for accurate binning - Gallery and explorer pre-sort by area descending and cap at 5K rows - Timeline preserves full temporal resolution
…orer The columnar streaming reader only extracts listed columns. The blur metric was missing, causing Sort by Sharpest to have no effect in the gallery and explorer views.

Summary
Replace full-file TSV loading with a streaming columnar reader and updated chart nodes. Fixes memory crashes on large datasets (56K+ rows,~81MB files) on Raspberry Pi.
