 - Morning Triage is triggered from `AppHeader` through `ICopilotAgent.RunMorningTriageAsync()`. Triage/Maintenance sessions register `RadarTools.CreateAll()` and `RadarWriteTools.CreateAll()`; write-like tools are permission-gated except `radar_score_commit`, which `RadarPermissionPolicy` pre-approves for scoring persistence. Final review decisions (`radar_save_review`) are user-owned and must not be auto-written by Morning Triage, but registered Ignore rules still auto-mark future matching commits as `Rejected` during ingestion.
 - `radar_score_commit` auto-marks still-unreviewed commits with score `0.44` or lower as `ReviewStatus.Rejected` with reason `auto-low-score`. Do not overwrite user-owned review states such as `Adopted`, `Later`, `Archived`, or existing `Rejected` rows.
 - Triage sends need the longer `MorningTriageSession.TriageSendTimeout` through `ICopilotSession.SendAsync(prompt, timeout, ct)`; the SDK default one-minute wait is too short.
-- Adoption draft/explanation generation and JSON repair sends need `AdoptionSession.DraftSendTimeout`; docs diffs plus URL fetches can exceed the SDK default one-minute wait and leave regenerated drafts empty.

+- Adoption drafts require SDK typed structured output for every selected model, including fallback models. Validate returned fields before persisting, and surface errors rather than silently resending failed structured turns.

 - timeout は idle 待ちの上限で、in-flight agent work の中止ではない。
 - `MessageOptions` に JSON schema / response format が無い場合、JSON-only prompt だけを強保証として扱わない。
+- Typed structured output が public API にある版では、実際の bundled CLI と対象モデルで synthetic な schema 送信を検証する。SDK の JSON deserialization は完全な schema validation ではないため、必須フィールドを保存前に確認する。構造化出力を必須とする機能では、未対応モデルのエラーを明示し、送信後の失敗を安易に無形式で再送しない。
 - beta.9 以降の tool filter は source-qualified (`custom:*`, `builtin:*`, `mcp:*`) を優先する。
