### LEARN-0014 — Where does independently developed Zulip scope navigation/search result and focus applicability, and where does our model fail to establish a guarantee?
2026-09-27 · stream B · prospective · revision
Before: The authored navigation generation guard protected current-view and focus effects, but independent application recurrence and alternative ownership/cache policies were unverified.
Conclusion: Revise guidance toward per-effect applicability: pinned Zulip preserves noncurrent cache data while guarding main selected-view continuations by list identity. Make client-fragment addressability explicit without inferring no-script enhancement. Shared feedback, auxiliary callbacks and deferred focus limit the inference.
Evidence: [ZulipNavigationSourceStudy](../../research/reviews/ZulipNavigationSourceStudy.md), [ZulipNavigationSources](../../research/reviews/ZulipNavigationSources.json), [2026-09-27-zulip-navigation-effort](../../research/evolution/cycles/2026-09-27-zulip-navigation-effort.json).
Remaining uncertainty: Static targeted ranges in twelve files, no Zulip runtime/upstream test execution or independent human/AT review. Auxiliary lookup/anchor continuations, deferred focus and callback wiring need a bounded follow-up before any race claim. One Zulip family supplies partial mechanisms, not full-contract recurrence or a no-script guarantee.
Supersedes: none recorded.
