Problem

The lagging same-epoch replica fixture covered only lite-07 and stopped after the successor group's first frame. IETF draft 17 and 22 use different resume request paths, so both need direct coverage.

Approach

Run the real-session fixture on all three protocols, asserting the interrupted suffix and complete successor group, timestamps, order, and no trailing delivery. Add a manual-clock JS mirror whose two replicas forward one original publisher's bytes, with a deterministic mid-group stall and session failure. Existing recovery passes without production changes. Remove the completed quest.

Current consumers are subscribers resuming through a warmed replica after their incumbent relay fails. The test fixtures exercise that existing behavior and run in the existing net CI suites.

Impact

• Public API: none.
• Wire: none. Draft 17's joining FETCH and draft 22's location filter already recover this case.

Alternatives

Avoided a new JS transport latency API: a frame gate models the lag deterministically without changing production interfaces. No retry, sleep, or timeout was added.

Validation

• just rs test -p moq-net: 2,865 passed, 8 skipped, including all three lagging-replica wire cases.
• bun test js/net/src/resume.test.ts: 69 passed.
• bun run --filter @moq/net check: passed.
• quest check: 452 documents valid; formatting and diff checks passed.
• After merging main at 43fc925 (which includes moq-dev/moq#6348): the three lagging_route_dies cases pass, including ietf_17_resumes_after_a_lagging_route_dies; bun test js/net/src/resume.test.ts passes 83 tests after renaming clock.advanceAsync to awaited clock.advance per moq-dev/moq#6222 (no logic change); just check js, rs, and quest modules pass.
• CI: just ci selects moq-net and @moq/net from the changed files, so both fixtures run in the PR and merge-queue checks. The local flake module cannot build the runner image on this host (unshare: write failed /proc/self/uid_map); this PR does not touch the flake.

Follow-ups

No product decisions or follow-up quests. Audited the in-flight resume end/dedup change; these tests do not duplicate its fixes or depend on them.

Quest outcome: complete as test coverage. All three Rust wire cases and the JS same-source mirror pass; the full moq-net suite passed 2,865 tests (8 skipped), JS resume passed 69 tests, and type/quest checks passed. No API or wire change, no open decisions, and no suggested product follow-ups. Source is committed at 93f9319.

Readiness remains blocked by the existing host restriction building the Nix runner image (unshare: write failed /proc/self/uid_map: Operation not permitted). Keep draft until just ci completes in a capable environment. No merge or enqueue requested.
