One actionable planning issue below: scope the FETCH close regression to current-build connections rather than enabling it across the released compatibility matrix.
Overall direction: the three focused follow-ups are sensible; reuse the existing shutdown APIs and typed error classification, and keep log-filter policy in the harness. A current-only FETCH regression is simpler than teaching the compatibility matrix to attribute shutdown behavior across released binaries.
Verification: inspected all four changed documents and the relevant fetch, reconnect, relay logging, and interop/compatibility code through GitHub. No tests or harness runs were executed.

[P2] Keep released peers outside the close regression
Turning on the idle-out check for the wire-compat FETCH cells also checks binaries this fix cannot change. test/interop/compat.sh:186–211 runs these cells through both current and released relays, and FETCH_TRACK invokes both current and released CLIs (interop.sh:663–665). The existing IDLE_CHECK=0 guard explicitly excludes those runs because released clients may not close cleanly and released relays lack the connection-identifying close log (interop.sh:33–40). Consequently, blanket enablement can fail wire-compatible released clients or produce an unreliable close verdict even after current moq fetch is fixed. Plan a current-build-only FETCH close regression, or explicitly restrict the assertion to the current CLI's connection on the current relay while preserving the released-peer exemption.

Agreed. Fixed in 2a4376f: the regression now runs a FETCH round with the current relay and current moq fetch under the idle-out check, and the wire-compat cells stay excluded since they mix in released binaries.

Do not enable the idle-out check for all wire-compat FETCH cells: those cells always set RELAY_BIN/MOQ_BIN and intentionally mix current and released relays and clients, while test/interop/interop.sh lines 33-40 disables the check precisely because released clients may not close cleanly and released relays do not emit the required close identifier. Enabling it across these cells would either fail on expected legacy behavior or provide no coverage; the regression needs a current-relay/current-fetch-only lane or a focused test that identifies only the current fetch connection.

Review comments at @quest/m1/interop-close-log.md:
- Around line 18-20: Add a per-round check alongside relay_connections() that
requires at least one parsed close line, so the check fails when close logs are
missing even if no connection IDs were parsed.
Review comments at @quest/m1/moq-fetch-close.md:
- Line 18: Update the wire-compat FETCH cell in the interop harness so it
verifies idle-out behavior despite its binary and client overrides disabling
IDLE_CHECK; add a targeted close assertion for this cell without enabling
unsupported checks for released clients.
- Around line 1-20: Update fetch_from so the established moq_tokio::Connection
is explicitly closed on every exit path, including inner errors and timeout_at
cancellation, rather than only after the final frame; enable the idle-out check
for the wire-compat FETCH cells as the regression.

Fixed in the plan: the prior P2 regression-scope finding is addressed by quest/m1/moq-fetch-close.md:17–22: the check now targets current relay/current fetch, preserves released-peer exemptions, and explicitly covers error/timeout cleanup. quest/m1/interop-close-log.md:18–20 also closes the missing-log coverage gap by requiring evidence of a connection.
No new actionable bugs found in this incremental review. The current-only regression is the simpler direction; no findings from my previous review remain open in these plans.
Verification: compared against f8a2852, separated merged-main changes from the two document edits, and rechecked the relevant fetch/relay/harness code. Planning-only changes; implementation behavior remains unverified. No tests run.

No new actionable bugs found. The additions address the remaining independent review notes: quest/m1/moq-tokio-terminal-errors.md:19–23 preserves a viable transport when another fails terminally, and quest/m1/moq-fetch-close.md:19–24 explicitly adds the missing current-only FETCH round to CI. My prior P2 remains fixed in the plan.
Direction: keeping the existing transport race and adding a focused current-build regression remains appropriately scoped. Compared the two document edits against 2a4376f and checked the existing race/status logic. Planning only; no tests run or implementation behavior verified.

There was a problem hiding this comment.
The planned tests do not cover the race-specific invariant immediately above. A classifier that marks TransportRace terminal when only one arm returns UnsupportedScheme would pass both proposed cases, since a mistyped scheme makes both arms terminal and refused TCP does not use the race, but it would incorrectly stop reconnecting when the other arm failed transiently. Require a mixed terminal/transient race regression so the fallback behavior is protected. (Written by GPT-5.6 Sol)

Summary
Plans three follow-ups from #5174 and #5192:
quest/m1/moq-fetch-close.md[XS]:moq fetchdrops its connection without closing, so the relay times it out.quest/m1/moq-tokio-terminal-errors.md[S]: with unlimited backoff, moq-tokio's reconnect loop retries errors that can never succeed (for exampleUnsupportedScheme), which already hitsmoqsink.quest/m1/interop-close-log.md[XS]: pin the interop harness's relay close log to info, so the idle-out check can't misread a clean close.Not planned: the reported
control: lagging latecomerfailure. Onmain's latest Interop run (38058995817) the control passes, and the only failure is TSduration-fidelity, whichts-duration-fidelity.mdalready tracks.Public API: none (planning only). Wire: none.
