 委譲では親が実際に委譲できる範囲を上限にする。読取り、書込み、コマンド実行、観測、レビュー、統合を混同しない。探索で対象を発見できても操作権限を得たことにはならない。
 
+### Featureの構成と実操作
+
+Featureの有効化、Tool・service・hookの登録、セッション内状態の初期化は権限を発行せず、それ自体に一律の起動認可を要求しない。外部への作用、保護データの読取り・モデルへの供給、購読・背景処理の開始は、起動中でも通常操作と同じ操作名と実対象資源で認可する。認可の要否をFeature単位のboolや起動専用の許可一覧へ置き換えない。
+
+操作名は完全一致で扱い、親の名前から配下操作への許可を推定しない。Workspaceのcollection操作の許可は、個別のTicket・Subject・Worker等への許可ではない。資源の種類を跨ぐ包含を認めず、パスの再帰範囲などの包含は所有する型の契約だけに従う。保存済みの旧Feature・Workspace grantは読取り互換のために保持しても、新しい操作や資源の包括許可へ変換せず、基礎権限を暗黙に追加しない。
+
+MCPはT-787の移行対象外とする暫定例外であり、既存の `mcp` 起動認可と `PermissionResource::Feature` を保持する。discoveryは外部プロセスを起動するため、既存の拒否を共通コード整理で失わせない。この例外を他のFeatureへ拡張せず、MCPの各呼出し・restoreに新しい操作認可が整備されたとも扱わない。
+
+### 認可境界と継続実行
+
+認可はHostに束縛された主体から、アクセス・供給・作用の直前に行う。共通のFeature内部処理やHost/provider境界を使い、Tool・WIP・typed service・起動・restore・hook・背景処理の入口差で省略しない。providerの所有・scope・capability・CAS等の検査は操作権限と合成する別の制約であり、互いの代替ではない。信頼されたFeature実装が境界を呼ぶ責務を持ち、任意コードの自動捕捉やsandboxを保証するものではない。
+
+起動への必須性は認可の要否から分離する。必須の保護処理が拒否された場合は起動を明確に失敗させる。任意処理は未開始・利用不可を診断し、空データや成功として隠さない。拒否されたデータを先に読んだりモデルへ渡したりせず、認可拒否と通信障害を区別する。購読・背景処理の次のアクセスや配送、保存済み入力の再供給でも現行権限を検査する。登録や履歴の復元は再認可ではなく、取消要求の受付は停止確認でもない。
+
+Subjectの権限未設定は保護操作の拒否であり、ローカルな構成の拒否ではない。Subject未接続Workerの既存Backend/provider契約と、明示的なstandaloneを区別し、接続障害や失効した接続をstandaloneとして迂回しない。主体の本体所有、委譲元、再委譲上限、現行policy、失効をHostで再確認し、保存済みの認可結果や共有clientから継続権限を推定しない。
+
+Subject Jobの実効権限は、対象Subjectに束縛されたJobの限定grantと現行Subject policyの積集合に限る。Job種別のgrant、凍結された起点、現行attempt・入力digest・期限・writer等の制約も維持する。Memory consolidationのgrantをJournalや一般Subject操作へ流用せず、権限未設定・旧Jobの起点欠落・grant不一致で一般Worker互換へfallbackしない。Job結果の保持や過去の入力の存在は、新しい読取り・供給・作用の許可ではない。
+
 ## 履歴とLLM入力
 
 LLMの生成に影響する入力は、リクエストへ加える前に履歴へ確定し、永続化形式からリクエストを再構成できるようにする。揮発的な入力の差込みでは、後のターンから発言やツール呼出しの根拠を追えなくなる。

+# T-787 操作認可境界の棚卸し
+
+## 観測範囲
+
+2026-10-28、HEAD `618880d38ded5e501d7c926006d1869282f06892` に対する共有作業ツリーの未commit差分を読んだ記録。T-787の本文とAGENTSの文書管理・検証規則を基準にした。実装とテストは並行して変更中であり、この記録は受入条件の充足、テスト成功、全入口の保護完了を示さない。将来の仕様正本や維持対象のAPI一覧ではなく、一律gate撤去で到達可能になる境界の調査証拠として残す。
+
+共通の判断基準は [正本・権限・実行の原則](../principle/authority-and-history.md#featureの構成と実操作) に置く。下表の操作名は完全一致の例であり、`ticket` が `ticket.create` を含むという意味ではない。`Workspace` 資源はcollection操作用で、別kindの個別資源を含まない。操作名を列挙した行も、列挙以外を許可するものではない。
+
+## Feature・経路別の境界
+
+資源名は `crates/server-api/src/authorization.rs::PermissionResource` のvariantを指す。共通境界欄は読取り時点で確認した呼出し位置であり、provider欄の既存検査とは別の制約である。通常の登録はローカル処理であり、表の外部処理が起動に必須かどうかとは分離する。

+以下、`WB/` は `crates/worker/src/feature/builtin/`、`WS/` は `crates/workspace-server/src/server/`、`W/` は `crates/worker/src/`。

+
+## 旧grant・Job・文書の整合
+
+差分の `ScopedPermission::covers` は操作名を完全一致で比較し、resource containmentはkindを跨がない。`Feature` variantと旧トップレベル名の保存形式は残るが、MCP以外の旧Feature grantは新しい操作の権限にならない。旧Workspace grantも個別Ticket/Subject/Worker等へ展開しない。schemaの自動書換えや全Subjectへの基礎権限付与を移行の説明にしない。
+
+`WS/subject_authorization.rs::job_permissions` はJournal/consolidationの限定操作と同じSubject資源に絞り、現行policyとの積集合を取る。`active_grant`、凍結originの現在の本体所有も検査する。一般Jobは空のSubject権限であり、旧Jobのorigin欠落は拒否される。これはJob grantだけで許可する契約でも、Subject policy全体をJobへコピーする契約でもない。権限未設定・domain不一致・失効を非Subject Worker互換へfallbackさせない。
+
+調査時点の維持文書 `docs/principle/`・`docs/development/` には、一律のFeature起動認可を要求する旧説明は見つからなかった。principleへ明示的な境界原則を追加した。`docs/report/` は過去の証拠であり、旧状態の記述を現行仕様に書き換えない。所有コードのコメントについては、`W/feature.rs` と `server-api/src/authorization.rs` の差分がMCP限定・操作境界へ更新されている。`worker-runtime/src/worker_backend.rs::saved_subjektiv_authorization_fixture_grants_only_exact_feature_activation` は依然 `subjektiv`・`workdir_catalog` の旧Feature名だけを許可するfixtureであり、新しいSubject resident操作・bound-checkの実接続証拠にはならない。
+
+## 生成契約の所有とscope
+
+実際の出力は `web/workspace/src/lib/generated/` と `openapi/server-api.json` である。付与された `apps/web/src/generated/` は既存出力先と一致しないため、新規folder作成・生成物コピー・手修正を行わなかった。所有者は `crates/server-api/examples/` と `src/repository_openapi_typescript.rs`、ts-rs系は `src/lib.rs` の対応関数である。
+
+- OpenAPIの生成・照合は `cargo run -p server-api --example export_openapi` と `cargo run -p server-api --example export_openapi -- --check`。既定の書込み先は `openapi/server-api.json`。
+- OpenAPI closureからの出力は `cargo run -q -p server-api --example generate_repository_openapi_types`、`generate_workdir_api_types`、`generate_runtime_api_types`、`generate_worker_launch_api_types`、`generate_ticket_api_types`、`generate_companion_api_types`。各exampleの `-- --check` は既存出力との照合。出力名はそれぞれのexampleが参照する定数を正本とし、一般的な `generated/` へredirectしない。
+- Memoryの出力は `cargo run -q -p server-api --features typescript --example generate_memory_api_types > web/workspace/src/lib/generated/memory-api.ts`。同様のts-rs系は `generate_auth_api_types`、`generate_skill_api_types`、`generate_repository_access_types`、`generate_drive_api_types`、`generate_legacy_typescript`。stdout出力と直接書込み型のexampleを混同しない。
+- `server-api/src/lib.rs` の `generated_worker_launch_api_contract_is_current` はOpenAPI closure出力を、`generated_memory_api_contract_is_current` はtypescript feature時のMemory出力を照合する。これらのCargo testはこの調査では実行していない。
+- 追加された `authorization/bound-check` と既存 `authorization/check` は `openapi = false` の内部契約。`PermissionResource` のts-rs deriveがあることだけから、全てのenumが既存Web artifactへ出力されるとは判断しない。新variantの影響するschema closureと実際の生成差分は所有者で確認する必要がある。生成物が古いとも差分不要とも、この読取りだけでは断定しない。
+
+## 未確認の接続・coverage
+
+以下はコード読取りから必要と判断した確認範囲であり、テスト失敗を観測したという意味ではない。
+
+- task-onlyの起動・direct install・restoreでFeature認可HTTPが0、Ticket Tool/WIP/serviceで未付与・範囲外・失効時に下流作用0、許可時に実作用完了を同じ接続で確認する。
+- providerの拒否、delegation失効・policy縮小・Subject本体交代、attachmentの入替え競合を実Host接続で確認する。fake clientで認可callbackを数えた証拠だけでは代替できない。
+- 初期resident入力の拒否時の読取り0・モデル供給0、許可時の取得・commit、optional Workspace summaryの未開始診断と通信障害分類を区別する。`load_initial_checked` が初期化で呼ばれる差分はあるが、その読取りだけでライフサイクル全体の成功を主張しない。
+- 保存済みpromptのsourceが設定変更等で除去されたrestore、同じbodyのcache再供給、Journal compactionの凍結済み参照、Subject Jobの凍結入力にも現行権限が適用されるか確認する。source objectが残る場合のcallback成功だけでは除去後の経路を証明できない。
+- Journal/consolidation Jobの限定grantと現行policy、origin欠落の旧Job、一般Job、current attempt・writer・期限拒否の組合せを確認する。Job入力のpre-request hook追加は、全Job操作のgrant整合の証明ではない。
+- 継続処理について取消要求後の停止確認、途中失敗cleanup、停止後の追加配送・読取り・作用0を確認する。登録時の拒否テストで継続中の権限変更を代替しない。
+- MCPのallow/deny、拒否時discovery spawn0、stdioの発見・各呼出し・restore・cleanup/retryを既存の粗い認可のまま回帰確認する。本Ticketの変更から新しい各呼出し認可を推論しない。
+- 旧保存grantを読めること、新しい操作へ暗黙展開されないこと、明示standalone・非Subject互換・Workspace障害が区別されること、生成契約の整合は実接続/生成チェックが別途必要。
+
+この調査でCargo build/testや生成処理は実行していない。文書のみの静的検査は実装の受入判定を代替しない。
+
+## 同日・候補安定後の追補
+
+上記は棚卸し時点の観測であり、以下はその後に実装担当が行った検証である。独立レビューの判断とは分ける。
+
+- `worker-runtime/src/worker_backend.rs` の旧Feature名fixtureを、Subjectの実操作とbound targetを検査するfixtureに更新した。task-onlyのFIFO・receipt replayはHost呼出し0、pending head修復はresident/Journal取得と保護入力checkpointを検査する。既存headの再修復では保護入力を再取得しない。
+- `worker.rs` の `protected_input_tests` はcached prompt、source除去後restore、fork・compaction・rewind、未知provenance拒否とhook後の再検査を扱う。Journalはstartup/compactionを区別し、空payloadは保護入力として偽装しない。追加の `backend_job_input.rs` とcontroller結合テストは、凍結Job入力を各モデル要求前に再検査し、拒否時にモデル要求・結果送信が発生しないことを確認した。
+- `server/tests/subject_authorization_tests.rs` の署名Host接続テストで、unset task、MCPのdiscovery前拒否、Ticket作成の下流作用、alias正規化、provider scopeとの積集合、attachment再接続、本体交代を確認した。`subjektiv_jobs_tests.rs` は限定Job grantと現行policy、origin/attemptの失効を検査する。これは任意のFeatureコードを自動監視できるという主張ではない。
+- 安定候補でroot `cargo check`、変更crateの通常suite（`server-api`、`tools`、`worker`、`worker-runtime`、`yoi-workspace-server`）、`server-api --features typescript` のsuite、変更crateのrustdoc生成、format・差分・状態契約名検査が成功した。restoreを含むsuiteにはcheckout内 `target/restore-test-environment/` 以下の専用config/data/runtimeを使用した。最初のServer再実行は隔離環境変数不足でpreflight失敗し、設定後の全suite再実行が成功した。preflightを削除して通してはいない。
+- OpenAPIと影響する各OpenAPI closure出力は所有exampleの `--check` で一致した。Webの型検査と変更型を使う関連APIテストが成功した。描画変更はなく、browser/E2E・稼働環境更新は実施していない。通常suiteで元から明示選択のignoredテストを実行済みとは扱わない。
+
+件数・生ログ・source識別はMRの検証記録に置く。これらの成功だけで受入条件の網羅、正式承認、統合、Ticketの完了を推論しない。
