fix(reconnect): a dropped replacement hands back to the draining predecessor - #8595
When a GOAWAY's replacement session connects and then drops while the old session still drains, Reconnect::closed queued Action::Offline ("nothing serves anymore"). moq_tokio::Connection then reported Disconnected, and established() and the live-session reads returned nothing, although the predecessor still carried live subscriptions until its handover ended. Code waiting on established() stalled. js/net's Reload had the same flaw: it cleared established to undefined while #draining still served. Found by the reconnect model (OfflineWhileServing.cfg broke OfflineMeansNothingServes).
Approach
Policy (rs/moq-net/src/reconnect.rs): when the live session closes while a predecessor drains and has not started its graceful idle close, closed queues Action::Migrating followed by Action::Retrying(err) instead of Offline. A predecessor already closing carries nothing and takes no new work, so that case still reports Offline. The predecessor's handover still bounds it: when it retires between sessions, Retired + Offline follow as before.
Connection (rs/moq-tokio/src/connection.rs): Shared::migrating(session, deadline) replaces the predecessor() + migrating() pair. If the policy's predecessor is the one Shared already mirrors, the replacement on top of it closed, so the handle swaps its live session and transport back to the predecessor. Otherwise the live session got the GOAWAY and is mirrored as the predecessor, as before. The mirror (Draining) now keeps the predecessor's transport so Phase::Migrating reports it truthfully. Shared::predecessor(None) became Shared::retired().
Session identity (rs/moq-net/src/session.rs): impl PartialEq + Eq for Session, where clones of one session are equal. Shared needs this to tell the two Migrating cases apart. Inferring it from action order instead (queuing Retired before a Migrating that replaces an older predecessor) failed TLC: a replacement could connect between the two actions, and Shared then marked the fresh session as migrating.
JS (js/net/src/connection/reload.ts): when the replacement closes, Reload serves #draining.serving() instead of undefined. js has no Migrating status; its documented shape is that a draining predecessor reads as connected.
Model: OnMigrating mirrors Shared::migrating, and EndClosed hands back to a predecessor that is not closing. OfflineMeansNothingServes now also accepts a closing predecessor and is checked in Handover.cfg and RestartWait.cfg. OfflineWhileServing.cfg is deleted. The verify-reconnect skill drops the finding, its coverage row names retired, and its sync commit moves forward.
Impact
Public API: moq_net::Session implements PartialEq and Eq (additive, kept by the maintainer). Two handles are equal when they are clones of the same session.
Behavior: Action::Migrating may now follow a replacement's close (its doc says so), with the close reason in the Retrying that follows. Connection reports Status::Migrating / Phase::Migrating on the predecessor in that window instead of Disconnected. js Reload keeps established on the predecessor and status at connected.
Wire: none.
Decisions
Maintainer, 2026-11-13: ✅ keep PartialEq/Eq on moq_net::Session ("additive is fine") (rejected: a new Action variant carrying the swap decision, which breaks every driver of the exhaustive Action).
Maintainer, 2026-11-13: ✅ drop this PR's follow-up quest/m0/uring-memlock-test.md, since moq-dev/moq#8546 keeps the same follow-up as quest/m0/test-flakes-2/uring-memlock.md (rejected: keeping this one instead).
Coordinator, 2026-11-13 (delegated by the maintainer): ✅ this quest belongs in m1 (rejected: m3). The fix is additive (only PartialEq/Eq on Session) and fixes a bug moq-dev/moq#7904 introduced; feat(net): connect policy lives in moq-net as a poll machine #7904 is on main but not on release, so the next cut would otherwise ship the bug. The branch keeps its quest/m3/ name; the quest file it deletes lives at quest/m3/reconnect-predecessor-status.md on main.
Choices made without asking, for review:
A predecessor already in its graceful idle close still yields Disconnected. It carries no subscription or fetch, so handing it out would be a stale session (the model's NoStaleSession fails on exactly that mutation).
Presence counters do not move on the swap back. The replacement's end was already counted when it replaced the predecessor, so started - ended stays 1 while the handle serves.
On the swap, the bandwidth estimates are frozen at the predecessor's latest value, matching how a GOAWAY handover freezes them.
js/net's residual: a redirected connection redials only its dead target asserted status !== "connected" as a side effect of this bug. It now asserts that the handle serves the draining session; its redial-target assertion is unchanged.
Caused by
moq-dev/moq#7904: made the connect policy a poll machine whose closed queued Action::Offline even while a predecessor served.
Validation
Policy: flipped the residual test into a_dropped_replacement_migrates_back_to_the_serving_predecessor (Migrating, then Retrying, predecessor still busy and open, then Retired + Offline(None) once its handover ends). Added a_dropped_replacement_goes_offline_over_a_closing_predecessor.
Handle, on real TCP sessions: a_dropped_replacement_hands_back_to_the_draining_session drains relay A, lets the replacement on relay B connect, aborts B, and checks Phase::Migrating { transport: Tcp }, poll_established ready, the handle's draining() being A's GOAWAY, stats present, and a new group still arriving through A. Fails against origin/main's reconnect.rs and connection.rs (test kept), passes with the fix.
JS: new a replacement that closes mid-handover hands back to the draining session fails without the reload.ts change and passes with it. All 270 tests in js/net/src/connection/ pass.
TLC: Handover.cfg (4 sessions, 1,241,415 distinct states) and RestartWait.cfg (236,871) pass with OfflineMeansNothingServes added. RedirectLost.cfg still fails on its own open finding, as intended. Mutations: reverting EndClosed to always Offline breaks OfflineMeansNothingServes, and ignoring closing breaks NoStaleSession.
just test -p moq-net -p moq-tokio: 4408 passed. just check on the head: everything passes except moq-relay's runtime_uring::uring_startup_reports_the_memlock_limit, which panics at runtime_uring.rs:1328 (expect_err("a worker needs locked memory")). It is pre-existing: just test -p moq-relay --features io-uring -E 'test(uring_startup_reports_the_memlock_limit)' fails the same way on a checkout of the base c681b7a095; moq-dev/moq#8546 tracks it.
Head 6ca927145 (this round's only change drops the follow-up quest): NEXTEST_NO_FAIL_FAST=1 just check ran all 12988 Rust tests, 12987 passed, and only the same uring_startup_reports_the_memlock_limit failed. Every other module passed, apart from sh/gh/nightly.test.py, which fails only because that variable reaches it: it passes in a plain just check and run on its own. cargo nextest run -p moq-tokio --all-features: 594 passed.
Merge of origin/main at be5db2ebc: two conflicts, resolved mechanically. In verify-reconnect/SKILL.md, kept this PR's single open finding with main's "Nightly runs every config" wording from moq-dev/moq#8628. In js/net/src/connection/migrate.test.ts, took moq-dev/moq#8597's rewritten "a redirected connection falls back to the configured URL once its target dies" test (it now redials the configured URL, so this PR's draining assertion there no longer applies; the dedicated hand-back test keeps that coverage) and dropped this PR's outdated comment. just check: 13030 Rust tests passed (the uring memlock failure is gone), @moq/net 3265 passed and 0 failed. TLC after the merge, with fix(net): a dead redirect target falls back to the configured URL #8597's model change included: Handover.cfg 1,720,621 distinct states, no error; RestartWait.cfg 296,679, no error; RedirectLost.cfg fails RedirectFollowed on its open finding, as intended. The skill's state counts now read about 1.7M and 300k.
Head 04f3977d9, fixing the online review threads: a_dropped_replacement_goes_offline_over_a_closing_predecessor now sees the replacement's close before the poll that starts the predecessor's graceful close, and asserts Offline(Some), then Retired + Offline(None); mutating the guard to ignore closing now fails it (it passed before). The moq-tokio hand-back test calls host_time() for its real sockets and points the resolver at a refusing listener before aborting B, so no redial can replace the handed-back session before the checks; 30/30 stress runs passed at about 0.07 s each. Raising the initial backoff instead, as suggested, also delays the GOAWAY's own jittered redial (measured 2.5 s), so it was not taken. just check on this head: 13030 Rust tests passed.
Merge of origin/main at 38a8dcd91: two conflicts with moq-dev/moq#8618, resolved mechanically. In Handover.tla, EndClosed's comment keeps both rules: every close retries whatever its error (feat(reconnect)!: the reconnect loop stops judging errors by kind #8618), and a predecessor not closing gracefully is migrated back onto (this PR). In verify-reconnect/SKILL.md, kept this PR's single open finding with main's wording; RestartWait's count reads about 290k. TLC: Handover.cfg 1,703,606 distinct states, no error; RestartWait.cfg 291,536, no error; RedirectLost.cfg fails RedirectFollowed on its open finding, as intended. Rust reconnect and connection tests (moq-net, moq-tokio): 192 passed. js/net src/connection: 270 passed. just check: 13040 Rust tests passed.
Follow-ups
None. The io_uring memlock test failure is tracked by moq-dev/moq#8546.

The policy reports Migrating, not Offline, when the replacement closes while
an open predecessor still drains, and moq-tokio's Connection serves on that
predecessor again. js/net's Reload does the same. Session gains identity
(PartialEq) so Shared can match the policy's predecessor. The Handover model
now checks OfflineMeansNothingServes in every config.

Reviewed changes
I reviewed the full diff at 6ca9271: the policy, the handle, JS parity, and the TLA+ model updates for a GOAWAY replacement that drops while its predecessor still drains.
Policy hand-back — Reconnect::closed now queues Migrating + Retrying(err) over a predecessor that is not closing, and still queues Offline over one that is.
Handle swap-back — Shared::migrating uses the new Session: PartialEq to tell a swap back to the mirrored predecessor apart from a fresh GOAWAY. Draining keeps the predecessor's transport so Phase::Migrating reports it truthfully.
JS parity — Reload serves #draining.serving() when the replacement closes. JS has no idle graceful close, so it has no closing case to mirror.
Model — OnMigrating and EndClosed are updated, OfflineMeansNothingServes now runs in Handover.cfg and RestartWait.cfg, and OfflineWhileServing.cfg is deleted.
I traced the presence counters through swap-back, a later connect, and retire→offline. started - ended stays balanced. The Retired → Offline(None) path after a swap-back clears the handle the same way it did before.
Reconnect policy and connection state now retain a serving predecessor when a replacement closes during handover. Rust and JavaScript tests cover continued service until predecessor retirement. The formal model and verification instructions reflect the updated migration and offline transitions.
Severity of issue fixed: Medium
Merge Risk: Low · previous review 6ca92
The reconnect handover fix looks sound. The new TCP regression test can fail intermittently, because it does not opt in to the host clock and its retry timing leaves a narrow race. Fix both in the test before merging to keep CI stable.

- Around line 2772-2773: Call kio::clock::host_time() at the start of
a_dropped_replacement_hands_back_to_the_draining_session to opt this
real-TCP-socket test into host-clock use before its timing-dependent backoff can
wait on the host clock.
- Around line 2827-2831: Increase the initial backoff in the test containing
session_b.abort from FAST to WAIT so the replacement dial cannot advance the
phase before the handback assertions; keep the healthy backoff at FAST and
preserve the draining-session final read.

I reviewed the test-only fixes since 28cc1b0.
Closing-predecessor ordering — a_dropped_replacement_goes_offline_over_a_closing_predecessor now waits for the replacement to close before the next poll. In Reconnect::poll, poll_idle marks the predecessor closing before the Live phase sees the close. So closed() now runs over a predecessor that is closing but not yet retired. The test asserts Offline(Some) and then Retired + Offline(None) in that order, which covers the !predecessor.closing guard.
Deterministic hand-back test — a_dropped_replacement_hands_back_to_the_draining_session now calls kio::clock::host_time() because it uses real TCP sockets. Before it aborts B, it points the resolver at a refusing listener, so no redial can replace the handed-back session before the checks run.

Merge with #8618 — In Handover.tla, the EndClosed comment now keeps both rules: #8618's "every close retries, whatever its error" and this PR's hand-back to a predecessor that is not closing. After the merge, Reconnect::closed in reconnect.rs still queues Migrating + Retrying over a predecessor that is not closing, and Offline otherwise. #8618's rule needs no branch on the error kind, so the two do not conflict.
Skill state count — verify-reconnect/SKILL.md now gives the RestartWait.cfg state count as about 290k, matching the TLC run the PR body reports.
