Extend the managed group stream with authoritative per-target terminal outcomes and structured failure classifications. Final client events are published first, followed by exactly one TargetFinished outcome for success, peer close, no-test, opening/runtime failure, removal, or cancellation.
Scheduler-owned cleanup now stops the receiver and seals subscriptions on natural completion, eliminating the event-consumer/join circular wait while preserving queued drain. TargetEventSubscription now yields ManagedGroupEvent, so consumers must handle Client and TargetFinished variants.
Strict-timeout regressions cover mixed success/failure, all-open failure, runtime failure, no-test ordering, removal, cancellation, and disconnection before join.
Consolidate graph modes into a single GraphMetric enum to support more granular metrics like one-way delays and server processing. Replace the "full graph" toggle with a dedicated TuiView system to improve UI state management and status line clarity.
Implement a scrollable and zoomable viewport for the TUI graphs, allowing users to pan through historical data using arrow keys and adjust the time window with zoom controls. This transitions graph rendering from sample-count based to timestamp-based for more accurate temporal visualization.
Introduce a toggleable graph scale (Auto, 100ms–2s) via the 's' key to provide better control over visualization ranges and implement smarter Y-axis bounds that handle signed versus non-negative metrics.
Enable switching between different RTT metrics in multi-target mode and add color-coded labels to the target table for better correlation with graph series.
Refine the TUI event loop to explicitly handle different exit conditions and ensure sessions stop correctly on idle timeouts or interruptions. Update UI labels to clarify when metrics or headers refer specifically to the first target in multi-target sessions.
Enable simultaneous probing of multiple targets within the TUI using a new target status table and multi-series RTT graph. Refactor target resolution logic into a shared module to support consistent behavior across CLI and TUI components.
Add unit tests for target normalization and address family filtering, and expand integration tests to verify column rendering and CSV output for multiple targets. Update subscriber config to drop oldest events under backpressure for better CLI stability.
Enable concurrent probing of multiple targets using positional arguments or the `--target` flag with unique labels. Update output formats to include a `target` column for logical attribution in multi-target runs.
Treat late replies as diagnostic events without RTT metadata to ensure consistent TUI statistics and add a visibility toggle for warning events in the packet panel.
Simplify the default table view by moving verbose columns to the verbose mode and allow users to explicitly request the default layout using `--columns default`.
Replace fixed output modes with customizable table, CSV, TSV, and JSON Lines formats. This allows users to select specific data columns and control header visibility for better integration with scripts and monitoring tools.
Update the machine-readable wall clock field to "event_wall_ns" for consistency and restrict visibility of internal rendering types. The extensive test suite was removed as part of this cleanup.
