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.
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.
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.
