+# P19-03 実装提出報告
+
+提出状態。受入は未確定。原受入「7名×3ルートの到達表があり、未制作内容は欠損として残る。」を維持する。14/88は変更しない。
+
+## 変更範囲
+
+Repair 1開始点e0420d57a381a1644357f0590536e1d47c9bca9fから、このディレクトリの指定5ファイルのみを変更した。原本、原子要件、work packages、decisions、TASK_SPEC、選定記録、frozen pins、ゲーム入力、marker registryは変更していない。git書込み、他worker起動、Runner操作、ゲーム起動は行っていない。素材追加なし。
+
+## 要件と検査の対応
+
+|TASK_SPEC implementation_requirements順|成果物|検査|
+|---|---|---|
+|1: 原7名×3ルート|REACHABILITY_TABLE.json / .md|expectedのPEOPLE/ROUTES、原本118–124行、atomic entityと21セルの完全一致。test_exact_cell_product|
+|2: 8カテゴリ、共通/人物固有の分離|JSON common_rules / cells.categories|CATEGORIES全件のcanonical比較。test_categories_and_citations|
+|3: 原本本文・行・status・anchorのsource SHA・owner|JSONの各共通項目/人物固有項目、catalog_evidence|expected.evidence/cite、verify。test_stale_record_evidence / test_owner_and_status|
+|4: 欠損、理由、担当、未知値pending|各character_specific、pending、natural_route_complete=false|test_no_invented_values_or_completion。D05/D08は未回答のまま|
+|5: docs内stdlibチェッカー/自己試験|check_reachability_table.py / test_reachability_table.py|stdlib importsのみ。選択対象外のdocs内配置|
+|6: read-only --check、厳密な表/Markdown|verify / verify_records / markdown|test_json_and_types / test_markdown_drift。--checkは書込み分岐を通らない|
+|7: 全frozen source mapと各identity|binding / selection|1368選択ファイルの完全map、marker/policy/engine、184-suite roster、329 .gd、baseline、spec→pins SHA。test_full_frozen_map_and_identities / test_real_source_and_baseline_changes|
+|8: UI/Runtime/save/Windowsの適用性|JSON route_support、MDルート別適用性|各ルートをcanonical比較。汎用UIラベル、原本登録Runtime、専用snapshotの限定証拠をcommon_rulesで参照|
+|9: 有意な負例と3種の正例|test_reachability_table.py|欠落/重複/誤人物/誤route/カテゴリ/引用/古い本文・SHA/値創作/誤完成/owner・status/JSON型/Markdown、実ファイル読込差替え、map差分とpins/marker/policy/engine改変。全3statusを含む正例|
+|10: P13パターン・原文保全|checkerのexpected/verify/markdown、原資料のbase blob照合|tools/check_p13_content_difference.pyのcanonical生成・厳密比較・read-only Git blob証拠パターンを参照。元ファイルは無変更|
+|11: 報告・残課題・外部gate|本報告、JSON accounting|正式試験・全単位独立レビュー・統合/finalは未実行と明記|
+
+原子要件はB-7.1〜B-7.6をsource_group_idsに含む61件の完全レコードを読込対象とし、JSON authority_snapshotsに保持する。人物キーと原名はそのentityから確認し、原本§6の順で並べた。原本§6は114–135行、§7は136–161行であり、実際の見出しと本文を照合した。人物別の原本仕様がない部分を共通ルールから創作していない。中断/保存の人物固有手順は原本に定義されず、work_packagesのP19-02受入が所有する欠損として残した。
+
+指定されたoriginal_relationship_state.gdには7名のrosterはなく、汎用subject_id等の明示入力検証のみがある。既存unique catalogのヒロインはheroine_anriのみ。監査IDには既存atomic entity.key（anri/fine/tomari/amelia/liz/mimi/satsuki）を使い、他6名の実装catalog ID、ライバル対応、初期値を創作していない。この実装欠損は表の欠損であり、原7名を削減する理由にしていない。
+
+## Repair 1: 4指摘の対応
+
+編集前に build/owner-handoff/p19-review-r01/ の ACTUAL_OPUS_REPAIR_DIRECTION.json、ACTUAL_WHOLE_UNIT_REVIEW.json、SPEC_HASH_REPRESENTATIONS.json を読んだ。
+
+- MEDIUM: coassignment_attack / zero_break / love_actions / threshold_route_loss と旧UIのlegacy_evidenceを追加。固定anchorの実際の本文・行・Git blob OID・file-bytes SHA-256を保持する。原本準拠statusはmissing、旧実装分類はlegacy_not_originalに統一。P18-01は一対一変換を禁止し、旧数値・日次制限は原本として未承認と明記した。UI定数は実際には98–101行であり、89–97行の無関係なラベルを除いた。共通ルール参照により各該当セルへ結び付けた。所有者・原本欠損・natural_route_complete=falseを維持。
+- LOW 独立試験: validate_legacyは候補とcanonicalの比較とは独立に、git showで固定anchorのソースを読み、引用行本文とgit rev-parseによるblob OID、現ファイルとの一致を検査する。test_independent_legacy_source_evidenceは実際のJSONと実ファイルを開き、git hash-object --stdin（書込みなし）でOIDを独立計算し、関数名とshield_broken/EXCLUSIVE_LOCKEDも確認。test_legacy_evidence_required_independentlyは対象全項目の証拠削除・空配列・無条件not implemented・古いOID/本文を拒否する。
+- LOW 中断参照: 全21セルのinterruption_cancellationに原本148・153行の本文とbaseline hash、および343–355行のconfirm_route_lockをlegacy_not_originalとして追加。人物固有欠損と担当は維持。
+- LOW ハッシュ表示: 263a01b943d8056727335fb76977c010298e1c229077f8da76e48683ba2e89bb は TASK_SPEC.json file-bytes SHA-256。3af3d9b931edc5449796662ad69bb6f67c80b48827a86565b1952931db68dd15 は Runner git-show stripped-UTF-8 contract spec_sha256。上記SPEC_HASH_REPRESENTATIONS.jsonのunchanged_file=trueが証拠であり、両者は同じ無変更ファイルを表す。checker定数と出力にも区別を反映。Git blob OIDは別のgit_blob_oidフィールドでありfile-bytes SHA-256とは区別する。

+--writeの実際の呼出しは同一checkout内で相対スクリプトパスと --project-root . を使用（上記は絶対パス表記）。--checkはMarkdownのバイト完全一致を確認。自己試験は12件OK。source bindingは1368ファイル一致、file_equality=true、actual_commit=e0420d57a381a1644357f0590536e1d47c9bca9f、native_evidence_reuse_accepted=false。git diff --checkはexit 0。構文は上記Python実行で確認。最初の編集用here-documentは一時ファイル作成制限でexit 1、変更は行われず、python3 -cで再実行してexit 0。native full・ゲーム起動・git書込み・Runner操作・他エージェント起動は行っていない。
+
+## 残る親成果・ゲームの欠損
+
+- P18-01: 原本3軸/盾の通常UI、承認済み初期値、本来の全単位受入。P18-02/03: 同配置・軽減・ブレイク・接触・閾値・確定遷移。既存旧汎用モデルの閾値を原本へ転用しない。
+- P19-01/02: 原本行動と全3種決闘、勝敗・費用・盾/履歴の一度だけ反映、通常入口、停止/取消/離脱/保存再開。原本状態保持のbackendを自然ルート完成としない。
+- P20-01/02/03: スキル/章・全エンド・図鑑と新規からの通常到達。P26-01/02/03: 人物別必要内容、状態接続、完成資産と制作受入。人物固有イベント/条件/履歴/立ち絵差分は欠損。
+- D05、D08はpending。未知の閾値・率・初期値もpendingのまま。P04の既存D05選択、P13の4件の制作followupも未解決。
+- この文書単位のnative GUI/Windows実行は適用外。global same-Windows、held gestures、全ゲーム受入はopen。固定入力一致から既存native証拠の正式再利用承認を推定していない。
+- Runnerの3 validator、原本§6–7と元受入に対する実装者から独立したwhole-unit Opus review、その後の通常prepare-integration/finalが必要。どの完了数・元台帳も変更していない。
+
+
+## Repair 2: BASE定義projectionと台帳更新の分離
+
+開始点Sは806de25068bc423136063791afcea811d251ee1b。編集前にACTUAL_OPUS_REPAIR2_DIRECTION.jsonとACTUAL_FAILED_INTEGRATION.json、immutable TASK_SPECと既存チェッカーを確認。最新run指示に従い、実マージ候補の作成・検証は実装担当では行わない。指定5ファイルのみを変更する。Repair 1の4修正を保持し、任意の低3指摘は延期したまま。
+
+### 実差分とallowlistの根拠
+
+git showによるBASE 8ca9263とmain 6e17caeのkey-level比較を行った。candidate 1875b03のwork_packages.jsonは6e17caeと完全一致。差分は次だけ（配列index 19=P19、remaining_deliverables index 2=P19-03）:
+
+|JSON path|差分|
+|---|---|
+|/19/current_summary|変更|
+|/19/updated_at_jst|変更|
+|/19/remaining_deliverables/2/current_execution|TASK_SPEC.jsonからROOT_CURRENT_ACCEPTANCE_STATUS.jsonへの参照更新|
+|/19/remaining_deliverables/2/current_summary|変更|
+|/19/remaining_deliverables/2/progress_summary|変更|
+|/19/remaining_deliverables/2/remaining_gaps/0, /1|通常integration/final待ちの進捗説明へ更新|
+|/19/remaining_deliverables/2/evidence|1件から2件|
+|/19/remaining_deliverables/2/submitted_commit|806de25068bc423136063791afcea811d251ee1bを追加|
+|/19/remaining_deliverables/2/updated_at_jst|変更|
+
+package allowlistはstate / legacy_state / current_summary / updated_at_jst。unit allowlistはstate / current_execution / remaining_gaps / updated_at_jst / submitted_commit / current_summary / progress_summary / evidence。state系は通常進捗遷移として明示的に許可し、同じ実registerに既存のキーだけを採用した。通常finalの完了時刻・source-ref用に、BASEの他unitで既に使われるcompleted_at_jst（P13-03）、implementation_commit（P13-03）、integrated_commit（P13-02）、integration_commit（P13-03）、normal_integration_candidate（P04-01）だけをunit階層で追加許可した。キーのprefixや任意のtimestamp/source_refキーは許可しない。allowlistの値は進捗メタデータとしてprojectionから全体を除外する。
+
+それ以外の全キーは未知キーを含め再帰的な値・型・有無を保ち、BASE projectionと比較する。30 package / 88 unitのID・順序・件数、全title/work/acceptance、phase/parent/depends_on/requirement_ids/decisions/supplement_ids/owner_roles/state_scope等を固定する。atomic_requirements.jsonとdecisions.jsonは実main差分なしのため引き続きbyte-exact。D05/D08のstatus/answerは変更不可。selection recordもbyte-exact。
+
+所有者集合・原子要件・authority_snapshotsはBASE blobのみから読む。各snapshotはanchored_base_commit、BASE blobのsha256、projected recordsを保持する。work packagesは全30/88定義を保持し、進捗を除外した。表の21セル、共通ルール・引用・status・owner・欠損・pending/null値は変更していない。Markdownには固定参照の説明だけを追加した。--writeは1回実行、--checkは読込み専用。
+
+### Repair 2 ローカル実行
+
+cwdとproject-rootは /Users/korizatou114/Projects/TheTree-managed-worktrees/p19-03-reachability/P19-03-TABLE-implement。
+以下は正式Runner試験ではない。実際の呼出しは各scriptをdocs/plans/original-completion-2026-10-02/execution/p19-03/配下の相対パスで指定し、--project-rootには上記実絶対パスを指定した。
+
+- python3 -B docs/plans/original-completion-2026-10-02/execution/p19-03/check_reachability_table.py --project-root /Users/korizatou114/Projects/TheTree-managed-worktrees/p19-03-reachability/P19-03-TABLE-implement --write: exit 0。

+
+上記3呼出しのstdoutはaudit_integrity=pass、formal_acceptance=pending_runner_and_independent_review、actual_commit=806de25068bc423136063791afcea811d251ee1b、selected_files=1368、anchor=1b07b87d3736e777932315a4bdde8b70cbf9cb23、file_equality=true、native_evidence_reuse_accepted=false。spec file-bytesとRunner contractの両hashも従来値のまま。
+
+実mainおよび失敗candidateの実blobをPath.read_bytes差替えで読ませる自己試験は、生成JSONとMarkdownのbyte完全一致を検証する。実registerの書換え・一時worktree・mergeは不要。合成完了/source-ref例も同じ検査を通す。各定義フィールドの変更・削除、package/unit objectの未知キー追加、package/unit/各定義listの件数/順序変更、D05/D08承認、atomic/decisions/selectionの変更を個別subtestで拒否する。既存12テストは維持。
+
+実merged-candidate確認: **Root preflight pending**。新S提出と通常validation後、Rootが最新main上の実Sについてラベル付き非正式isolated preflightで同じ3チェッカーを実行する。その後に別Opus whole-original re-review、通常prepare-integration/finalが必要。今回のローカル成功やworker exit 0は受入ではない。正式進捗14/88は維持。native GUI/Windowsは本単位に適用外、global Windowsとゲーム受入はopen。
+
+自己試験の探索版2回は全recordや深い履歴データの同型フィールドまで反復走査して時間がかかったため中断（各exit 130、KeyboardInterrupt）。package/unitの異なる定義キーごとに変更・削除を検査し、ネストした定義値は全体を比較する形へ整理した。BASE blobを一度実読込して負例ループ内で再利用し、各負例ごとのgit show起動を省いた。検査対象・既存controlは削除していない。shell here-documentを用いた初回の読取り差分確認は環境の一時ファイル制約で失敗（exit 1）、python3 -cで同じ確認を実行した。
+
+最終p19-negative呼出し: python3 -B docs/plans/original-completion-2026-10-02/execution/p19-03/test_reachability_table.py --project-root /Users/korizatou114/Projects/TheTree-managed-worktrees/p19-03-reachability/P19-03-TABLE-implement
+
+exit 0、出力: Ran 16 tests in 16.285s / OK。実main/candidate正例、合成final正例、全package/unit定義フィールド負例と既存controlを含む。git diff --checkもexit 0。最終差分は指定5ファイルのみ。生成前後のJSONを比較しauthority_snapshots以外の全フィールドが一致することも静的確認した。
+
+同じp19-tableコマンドを絶対scriptパスで再確認（exit 0、同じpass出力）。呼出し前後にこのディレクトリの全通常ファイルSHA-256 mapを比較し一致: Read-only byte determinism: pass。最終git diff --checkもexit 0。

+  "status": "pass",
+  "summary": "I re-reviewed the whole original P19-03 unit at 903a2c5, read-only. I did not edit or run anything.\n\n**Original acceptance (「7名×3ルートの到達表があり、未制作内容は欠損として残る。」)**\n- The acceptance text is identical to work_packages.json:9021.\n- I read BASELINE §6 (114–135) and §7 (136–161) directly. The 7 names in REACHABILITY_TABLE.md (アンリ/フィーネ/トマリ/アメリア/リズ/ミミ/サツキ) match lines 118–124 in order. Each cell cites its own character line (118…124).\n- The 21 cell IDs map to existing atomic records AR.heroine.<key>.route.{love,ntr,corruption}. I checked anri.route.love directly: B-7.1, entity key and original_name match.\n- Every cell has all 8 categories: entry events, state conditions, duel win/loss, route/selection effects, interruption/cancellation, save, history/marks, current reachability.\n- Common rules are kept separate from per-character content. All 23 common rules cite exact original line text plus the baseline hash, and the quoted text matches the BASELINE file.\n- Every per-character item is recorded as 欠損 / 原本未定義 / D08 pending, with a reason, an owner and natural_route_complete=false. The owners are P18-02, P19-01, P19-02, P20-02, P26-01 and P26-02, and they match those deliverables' titles and work in work_packages.\n- D05, D08, thresholds, rates and initial values all stay pending/null, with no invented numbers.\n\n**Checked against the actual game source**\n- data/characters/mvp_unique_characters.json contains only heroine_anri and rival_rai. None of the other six names appear anywhere under data/.\n- original_relationship_state.gd only validates and holds generic fields; it has no roster. So \"implemented\" is limited to that narrow storage, and \"partial\" to the affection/shield-max invariant, the snapshot container and the identity check.\n- There is no duel, history or pregnancy code anywhere in autoload/scripts/scenes. lust and netorare appear only in state validation, never in updates. The \"missing\" statuses are honest.\n- Legacy shield, route-lock and UI-label code is cited with blob OIDs and labelled legacy_not_original, never credited as an original route. Backend support is not called a completed natural route. Using atomic keys while leaving the six missing catalog IDs as explicit gaps is the honest choice and invents nothing.\n\n**Repair 2 (projection)**\n- PACKAGE_MUTABLE and UNIT_MUTABLE allow only progress, reference, evidence and time fields that already exist in BASE.\n- Every other field, including id/title/work/acceptance/depends_on/requirement_ids/decisions/owner_roles, is compared exactly against the BASE 8ca9263 projection. Type is preserved via json.dumps, so True does not compare equal to 1.\n- atomic_requirements.json, decisions.json and the selection record stay byte-exact against BASE.\n- test_every_register_definition_field changes or removes each distinct definition key, adds unknown keys, and alters list counts and order. D05 and D08 flipping to approved is rejected, and the real main 6e17cae and candidate 1875b03 registers are accepted as positive cases.\n- The fact comparison shows only authority_snapshots changed. I confirmed the 21 cells, common rules, statuses, owners and gaps are unchanged from the previously passed 806de25.\n\n**Scope and validation**\n- The diff touches only the 5 allowed files under execution/p19-03/.\n- All 3 registered checks ran on 903a2c5 and exited 0. p19-table binds actual_commit 903a2c5, 1368 selected files, file_equality true. p19-negative ran 16 tests, OK.\n- The Root non-formal preflight on S plus latest main (7f9b63b) also passed all 3 checks. It is not normal integration or final.\n- The earlier failed integration (1875b03) was recorded honestly and fixed without changing any original definition. No test was deleted or disabled.\n\n**Open items**\n- D08 and per-character content, P18–P20/P26 gameplay, and global Windows/game acceptance all stay open.\n- No credit before normal prepare-integration/final and the ledger update. Only then can the count move from 14/88 to 15/88.",
