### LEARN-0013 — Can obsolete history/navigation completions affect newer intent, and does separating completion ownership from focus ownership prevent it?
2026-09-27 · stream F · prospective · revision
Before: The single-response continuation policy preserved newer search focus but left competing history/success/error completions unresolved; focus-at-swap alone might not be sufficient.
Conclusion: Revise operational guidance: validate navigation ownership before content/URL/title/feedback effects, including stale errors and newer failure, independently of focus permission. Prior policy misses obligations in 12/12 adversarial rows; authored guard meets 12/12. Pause fixture work for independent source contrast.
Evidence: [NavigationOwnershipExperiment](../../research/reviews/NavigationOwnershipExperiment.md), [NavigationThreadReview](../../research/reviews/NavigationThreadReview.md), [ownership-result](../../research/experiments/navigation-history/ownership-result.json), [2026-09-27-navigation-ownership-effort](../../research/evolution/cycles/2026-09-27-navigation-ownership-effort.json).
Remaining uncertainty: One authored htmx family and author-model review, not production recurrence or AT validation. History adapter is pinned implementation-dependent; pending-state, multiple-miss and lifecycle limits remain open. Three distinct protocols are not a comparable diminishing-returns window.
Supersedes: none recorded.
