Categories overlap. Runtime includes authored fixtures and negative controls. Family labels group related evidence; they are not counts of independent applications.
Independent human profile reviews: 0/17. Full-contract independent-use counts unassessed: 17/17.
Frozen pilot after adjudication: named 18/24; prose 18/24. Initial unsupported-claim count: 2 per condition (historical only); adjudicated flags remain qualitative, with no revised numeric count. Independent human validation: pending. Decision time: unknown. [Adjudication](../../research/evaluations/language-pilot-01/submitted-review-01/adjudication.md).
One frozen development pilot with submitted model review; six matched briefs. Equal aggregate scores do not establish equivalence. Stable anchors are consumed development cases, not fresh held-out tasks.
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.

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: 14. 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.
Review backlog and evidence gaps remain in [FEP-WP-0002-seed-language-validation](../../workplans/FEP-WP-0002-seed-language-validation.md), [FEP-WP-0003-contrasting-schools](../../workplans/FEP-WP-0003-contrasting-schools.md), [FEP-WP-0006-language-evolution](../../workplans/FEP-WP-0006-language-evolution.md).
Open limits: Authorized retention and export are separate decisions. Complete contract recurrence and fault-tested deployed behavior remain unverified.
Open limits: No native-unload, crash, multiple-tab or access-revocation guarantee. Full base/draft/current merge contract is not verified in deployed frontends.

## Recorded learning
### LEARN-0001 — What do pinned recovery implementations establish?
2026-09-25 · stream D · retrospective · revision
Before: Documentary motivation did not locate draft/outcome mechanisms in frontend code.
Conclusion: Zulip and Element locate partial draft/outcome mechanisms; complete pattern recurrence is still unknown.
Remaining uncertainty: No CDN or upstream deployment validation.
Supersedes: none recorded.
### LEARN-0010 — How do stale activation writers and unfinished drafts constrain updates?
2026-09-26 · stream E · retrospective · revision
Before: Release experiment left activation conflicts and reload policy unexecuted.
Conclusion: Conditional replacement rejects stale writers; explicit reload policies preserve or refuse transition, with schema recheck after navigation.
### 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.
Remaining uncertainty: One authored application, no independent recurrence or usefulness gain. Accessibility, delayed scripts, interrupted transport, real intermediaries and offline availability remain open.
### LEARN-0012 — Does enhanced route replacement need explicit continuation and feedback policy that respects changed focus ownership?
2026-09-27 · stream F · prospective · corroboration
Before: Native controls alone do not establish enhanced focus/feedback semantics; delayed responses should respect focus moved to another surviving task. Modal return is not automatically route continuation.
Conclusion: Corroborated in 22 cases: raw same-ID link focus survives but this fragment contract leaves stale title and silent failure; authored heading/status policy works and preserves newer search focus. No AT speech or universal heading policy established.
Remaining uncertainty: Author-model DOM evidence, no human/AT validation or independent recurrence. Delayed history focus, competing requests, delayed scripts and interrupted enhancement remain open.
### 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.
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.
