## Learning and effort
Selected retrospective outcomes, not a complete historical census. All entered 2026-09-26; historical effort unmeasured. Prospective cycles begin after this baseline.
Ten selected retrospective outcomes (not a historical census), followed by prospectively registered bounded cycles. Retrospective effort remains unknown.

One bounded question counts at most one consequential outcome. Corroboration and inconclusive work remain visible separately. Fewer than three comparable cycles: no trend assessment.
## Coherence and maintainability
Profile hashes and local references passed validation when this report was generated. That checks traceability, not source truth or external URL freshness.
Profiles with unknown last substantive review date: 17. Assessment dates record this metadata review, not a new substantive validation. No age-based freshness claim is available for those profiles.

Coherence metrics (ambiguous selections, unjustified relations and overlap resolved): not measured. Conflict Copy / Explicit Reconciliation overlap remains an explicit open question.

### LEARN-0011 — Can a public route preserve selection and complete-document availability across native/enhanced entry, history and HTTP caching?
2026-09-27 · stream B · prospective · corroboration
Before: Native href/GET contracts plus representation-aware routing and cache selection should satisfy this narrow obligation; documentary support lacked runtime checks.
Conclusion: Corroborated in pinned htmx fixture: native and history paths work; missing Vary reproduces fragment-as-document reuse in both browsers. Existing obligations stand; no new pattern or promotion.
Evidence: [NavigationHistoryExperiment](../../research/reviews/NavigationHistoryExperiment.md), [result](../../research/experiments/navigation-history/result.json), [2026-09-27-navigation-effort](../../research/evolution/cycles/2026-09-27-navigation-effort.json).
Remaining uncertainty: One authored application, no independent recurrence or usefulness gain. Accessibility, delayed scripts, interrupted transport, real intermediaries and offline availability remain open.
Supersedes: none recorded.
