Retain only the 256 most recent target outcomes in the final group snapshot while tracking total, successful, failed, and discarded outcome counts. Publish each authoritative TargetFinished event before inserting into the bounded history.
Update CLI/TUI exit decisions to use aggregate counts and add a dynamic churn regression proving every outcome remains observable while join retention stays bounded.
Track desired membership separately from active target state and make natural completion an explicit group policy. Empty authoritative updates now remove all targets without terminating the scheduler, while static CLI groups retain all-target completion.
Document that construction still requires an address-family-defining target and add regressions for empty replacement, later re-addition, idle control responsiveness, idle cancellation, and finite static completion.
Consume structured per-target outcomes in the streaming CLI and TUI so mixed failures remain visible while successful targets still produce output. Return a failure status when every target fails, and keep interruption behavior distinct.
Add strict-timeout integration coverage for mixed continuous completion and all-open-failure exit status, plus focused TUI outcome-state tests.
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.
Store hub closure under the same lock as subscriber registration so permanent shutdown cannot race with a late subscription. Sealing remains idempotent, wakes current consumers, preserves queued events for draining, rejects future subscribers, and ignores later publications.
Regression tests cover queued drain, blocking wakeup, idempotent sealing, and late subscription rejection.
Treat a decoded, authenticated, token-matched close flag as a session-level signal after classifying the packet. Classification events now deterministically precede SessionClosed for pending, duplicate, retained-timeout, evicted-late, and untracked sequences.
Wrong-token and bad-HMAC close packets remain non-terminal. Public event documentation records the ordering contract, and focused regressions cover every correlation class.
Snapshot sent counters when a runtime leaves its live session state, and expose PeerClosed from the single managed runner instead of folding it into TestComplete. Group timeout polling now recognizes a peer-closed runtime before attempting another operation, preserving the same provenance and counters.
Regression coverage verifies single and group peer-close outcomes, finite completion, cancellation, no-test completion, and final counters.
Revert the GitHub Actions runner to ubuntu-22.04 for better compatibility and ensure the "full" feature set is passed to cargo-dist during the build process.
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.
Introduce a managed group runner to support concurrent probing of multiple targets over a single UDP socket with coordinated send pacing. Refactor the existing client logic into a reusable SessionRuntime to support both individual and grouped session management.
Update README with comprehensive build/verification instructions and modify the client comparison script to consume CSV output instead of the legacy machine format.
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.
Move the main execution logic to a dedicated internal module and create distinct entry files for each binary to improve project structure and build configuration.
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.
