Features:

  • Line chart of range node values plotted over domain node values
  • Multi-fingerprint overlay (up to 3 series) with interactive selection
  • Change detection markers: FixedThreshold, RelativeDifference, StdDevAnomaly, EDivisive with type-specific symbols and colors
  • HorizontalLine for FixedThreshold min/max bounds
  • Auto-detect terminal size for chart dimensions
  • Braille rendering by default (unicode/ascii via --style flag)
  • Alternate screen buffer for clean full-screen display
  • Interactive viewport scrolling: arrow keys or h/l to scroll, Home/End to jump, q to quit
  • Fingerprint selection menu when multiple fingerprints exist
  • Fixed Y-axis range during scrolling for consistent visual comparison
  • Centered title showing range node name and folder

Data retrieval:

  • New ValueService.getChartData() method using separate recursive ancestor CTEs per node, joined in Java by root_id (~480ms vs 22s with the full getGroupedValues CTE)
  • DISTINCT ON (root_id) deduplication to handle DAG fan-out through shared edges
  • Sequential index X-axis (domain values may be non-numeric)

Interactive line chart with change detection markers
5497b4e 
Adds a 'chart' command that renders node values as an interactive line
chart inside the terminal. Features:

- Multi-fingerprint overlay (up to 3) with 'f' key switcher
- Optional --domain for x-axis ordering (upload order by default)
- X tick labels from root payload (timing.start / BUILD_ID / sequence)
- Change detection markers pinned to the series line, filtered to
  same-metric detections only, toggled with 'c' key
- Marker legend and label decluttering via aesh-charts native support
- Tab completion restricted to plottable (numeric) nodes
- REST endpoint GET /folder/{id}/alignedValues
- Notice when no detections target the charted metric
- Quarkus bumped to 3.39.5, aesh-charts to 3.18.2
- NotificationTest adapted for String... varargs H5mTest.run API
