Moving this quest leaves rs/moq-relay/src/auth.rs:277 pointing to the deleted quest/m1/origin-narrowing.md; a repo-wide git grep finds this as the only remaining old-path reference. Update it to quest/m1/auth/narrowing.md so readers of Lease::ended can still reach the plan.

Fixed in 6b8d1be (also updated the new quest/m1/auth/request-token.md reference that arrived with main).

If the follow-on implements this summary literally, it will reject a route with a newer sequence number whenever its metric is higher. RFC 8966 §3.5.1 instead considers an update feasible when its sequence number is newer regardless of metric, or when the sequence number is equal and the metric is lower; the newer-sequence case is what allows recovery onto a more expensive path after a withdrawal. Describe both cases so this plan does not turn Babel's loop-avoidance rule into a reachability failure.

Agreed, fixed in 48a1c18: a route is feasible when its sequence number is newer at any cost, or equal and cheaper.

WalkthroughThe M1 AUTH materials add a quest for live origin-grant narrowing and update related links. The previous general origin-narrowing document and relay peer-set proposal are removed.

- Around line 25-27: Correct the Babel feasibility-condition summary by
replacing the claim that routes are accepted only when cheaper than the best
seen. In the feasibility discussion, state that a newer origin sequence number
is accepted regardless of metric, while an equal sequence number requires a
lower advertised metric than the stored feasibility metric.

There was a problem hiding this comment.
When routes have equal costs, including common cost=0 sibling links, the hop chain still has routing duties after stitching identity moves: route_order in rs/moq-net/src/model/origin.rs:585-600 ranks identified over anonymous routes, then uses hop count and a hash of the entire chain before recency. Saying only loop prevention and request exclusion remain lets the follow-on drop those inputs and select the newest route instead of the shortest, stably hashed route. Include replacement decisions for anonymity, hop count, and deterministic tie-breaking in this plan.
