Exercise a real one-target ManagedClientGroup through timeout, Draining, a gated retained reply, LateReply classification, local close, and authoritative TargetFinished publication. Synchronize release after EchoLoss and a scheduler-handled no-op update so the ordering is deterministic rather than delay-dependent.
Add a silent-server control that verifies completion only after the final-drain deadline, and assert bounded join, queued-event draining through disconnection, target counters, terminal outcome equality, and group aggregates in both cases.
Harden the analogous single-client late-drain test with a viable one-probe run window and packet-shape checks. No production final-drain behavior change was required.
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.
After publishing the authenticated reply classification and session-close events, mark the target PeerClosed while the receiver still holds its lock. Wake the scheduler to publish and account for the single authoritative terminal outcome.
Add controlled-order regressions proving later scheduler sends and target removal cannot overwrite peer-close provenance, counters remain intact, and ordinary replies stay active.
Block the group scheduler on its control channel when no opening, pacing, or final-drain deadline exists. Preserve bounded timed waits whenever scheduled work remains.
Cover no-deadline blocking, channel disconnection, deadline wakeups, and empty dynamic-group update, stop, and drop behavior with bounded tests.
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.
Exercise the ordinary OpenTimeout path with a bound UDP peer that receives every configured opening attempt but never replies.
Bound event disconnection and join completion with one strict deadline, then verify the authoritative terminal event, structured failure, aggregate counters, and retained outcome.
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.
Advance delayed managed schedules to the latest due cadence slot and then directly to the first future deadline. Apply the same absolute-cadence behavior to the single runner and group burst/staggered pacing, while leaving the manual Client send API caller-paced.
Bound receive waits by the next send deadline so 10 ms intervals are not hidden behind the managed socket timeout. Add deterministic delayed-slot, finite-end, burst, staggered, and receive-bound 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.
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.
