Add a scheduler-owned saturating peer-close counter shared with the group session. Update it before best-effort TargetFinished publication so bounded subscriber overflow cannot hide the live shutdown condition, while retaining the existing events, bounded history, and aggregate accounting.
Make grouped CLI and TUI supervision consult the durable count on each existing activity loop and funnel both count and event observations through one-shot stop policy. Preserve interruption suppression, queued-event draining, structured failures, drop reporting, and peer-close diagnostic precedence.
Cover scheduler-only accounting, non-peer exclusions, receiver and removal races, deterministic capacity-one DropOldest eviction with an active target, frontend one-shot policy, and the existing process-level peer-close and interruption behavior.
Replace the manual single-target ClientSession loops in the stream and TUI adapters with ManagedClient::start_with_subscription so the existing worker owns opening, deadline-aware pacing, receive handling, timeout polling, draining, and close.
Use bounded subscription waits for interruption and input polling, drain queued events before and after join, and report per-subscription drops without changing output, statistics, labels, summaries, warning, or peer-close policy. Add process and unit regressions for 10 ms cadence, interruption, final-event draining, TUI terminal state, and overflow visibility.
Record a continuous peer-closed TargetFinished event as the reason for requesting group shutdown and stop each CLI/TUI group at most once. Drain the managed subscription and join before applying exit policy so queued output and target failures are preserved.
Give peer closure precedence over the cancellation caused by that internal stop while keeping explicit interruption and finite-run behavior distinct. Add bounded process regressions for partial closure, mixed failures, queued rows, and interruption plus focused TUI policy coverage.
Keep PeerClosed as a distinct successful library outcome while treating it as an error at the CLI and TUI boundary for uninterrupted continuous runs.
Track aggregate peer-close outcomes independently of bounded recent history and cover finite, continuous, grouped, mixed-failure, interruption, and TUI status behavior.
Track a monotonic discarded-event count per bounded subscription for all overflow policies, including after hub sealing or disconnection. Preserve nonblocking publication and existing queue policies.
Warn once in streaming CLI output and mark TUI summaries/status as incomplete when DropOldest discarded events. Add exact overflow-counter and incomplete-marker regressions.
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.
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.
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.
Allow one-way delay samples to represent negative values caused by wall-clock skew between client and server. Update CLI output and statistics collection to correctly handle and report these signed durations.
