Record LEARN-0017: traced Zulip target-lookup/anchor guard gap (corroboration)

Second cycle in comparison group B-independent-navigation-source-v1, a
naturally-motivated follow-up to LEARN-0014's ZN07 finding rather than a
manufactured repetition. Traces the target-message lookup and anchor-
navigation fetch continuation to their unconditional completion points in
message_fetch.ts: neither participates in the opt-in current-list-identity
guard used elsewhere in the same file, and no located test covers a
stale-navigation scenario. No reproduction or defect claim; static source
read only. CAND-0009/CAND-0010 evidence and gaps updated accordingly.

Declined to reopen the paused local navigation fixture to force a third
cycle in an existing group, per the prior agreed pause and WP-0006 T03's
own rule against manufacturing cycles to hit a count.

## Second B-independent-navigation-source-v1 cycle — 2026-09-27
LEARN-0017 preregistered at `884803c`, a naturally-motivated follow-up to LEARN-0014
(not a manufactured repetition): it answers ZN07's open question about the target-
lookup and anchor-navigation continuations' missing guard. Comparison group
B-independent-navigation-source-v1 now has two cycles, still short of the three
needed for a comparable-window returns review. See
[research/reviews/ZulipTargetLookupCallPath.md](../research/reviews/ZulipTargetLookupCallPath.md).
T03 remains progress: reopening the paused local navigation fixture to manufacture
a third cycle there was considered and explicitly declined, per the existing agreed
pause and this task's own rule against forcing a count. A third comparable cycle in
this or another group should only happen when a genuinely useful next question
arises. No trend claim, no M1/M2/M3 closure.
