+{"action":"request-repair","task_id":"P28-02-EQ","reason":"Stage S3a run 32288e966a844f5baec4dc931bc281a5 ended as planned after 726.041 s: formal status blocked with the low finding 'stage S3a complete, next S3b'. This is a staged checkpoint, not a failure. All 6 conditions are still pending; repairs 5; no S; no active run. Root preserved 39 files and 6 raw files (retained-s3a-32288e9-r01/RETURN.json SHA 3752c3ee5880ac82f2585a1b94e1c7ef0adaf02c406125c9fc9eada1bae83af3) and joined the local results (ROOT_S3A_LOCAL_JOIN_32288E9.json SHA db712aea5390fd6fe9313954a1f77ce07df49556f21633437f8baa1c1a6f0701). Unit runs of 72, 85, 91 and 91 tests all embedded exit code 0, with final output SHA 02221ae41e5dd40ecdac0ec0d7ffc657f265d3194c3817583c2b88ad375f132b. Runs 03 and 04 saved full stdout to a file with its SHA while the provider printed only the tail, and they are joined on that basis, without claiming full provider-stdout equality. All 72 earlier test bodies are unchanged and 19 tests were added. The S1 comparator, the frozen materials and the earlier failure raw are unchanged, tracked product source is unchanged, and every change is inside eq/. Root's two incorrect join attempts are preserved as failures. A limited read-only check found no high or medium false PASS; this is not the formal review. Request the normal repair so the same W continues with stage S3b under EQ_S3B_STAGE_PLAN.txt. SPEC, TASK, the 6 conditions, eq/references, eq/registration, clarifications r01, r02 and r03 and the staged and S3 plans are unchanged. Decided by Claude Opus 5.5 in the Desktop control session (message 334); not a CLI commander result."}

+{"action":"run","task_id":"P28-02-EQ","reason":"Use only after Root verifies through the normal gates: repair_ready, repairs 6, no S submitted, no active run, and the S1, S2 and S3a files still present unchanged in the W. Run repair 6 of P28-02-EQ once on the same W from base 2549cf7d6992560b850bbd11934e3c14b39a1988 with the single worker codex gpt-6-astra, doing only stage S3b. Deliver EQ_S3B_STAGE_PLAN.txt in full as part of the one supplementary key, together with both S3 plans, both staged plans and this decision; clarifications r01, r02 and r03 stay read-only in build/eq-staged-readonly-r04. Start by reading eq/PROGRESS.md and eq/IMPLEMENTATION.md, including the S4 binding requirements at the end, and reuse the S1/S2/S3a types, paths, schema, API and code without redesign. Do not delete or rewrite E3, the 91 existing test bodies or the failure history, except for fixes a failing test requires. S3b scope: E4 in R and O over five paths in order, in dedicated scenario intervals. (1) A state-changing build_facility command through submit_command (simulation_runtime.gd:476), with definition and origin chosen by a fixed scan using the product's public placement check, or NA with a reason when nothing is placeable; record after submit and after one advance_minutes(1). (2) One tick. (3) A direct restore_snapshot(P), with exact P reproduction after normalization and 0 SAVE events. (4) A load_from_path success from a fixed-path, fixed-metadata SaveService.save_snapshot, equal to X(P, ev_load) with exactly 1 SAVE_LOADED. (5) A rejected build_facility with an empty definition_id plus one tick, with all bookkeeping changes recorded. Each path records create_snapshot() and latest_snapshot as full typed trees. latest_snapshot staying unchanged after a path without a tick is a recorded product fact, not cache staleness; staleness is judged later by cross-version comparison. E5 covers 4 targets (create_snapshot() return value, latest_snapshot, snapshot_published argument, state_updated argument) by nested dict (systems.runtime.id_generator.counters gains '__p28_eq_probe': 1) and nested array (systems.runtime.domain_events.published_ids gains '__p28_eq_probe'), in both directions. Signal arguments are held from the probe's existing connection and mutated outside the handler. Outside to inside compares internal create_snapshot, latest_snapshot and the pre-read latest_digest before and after. Inside to outside checks the returned value against its deep copy after one tick. The expected aliasing of latest_snapshot and the signal arguments (:12617-12621) is recorded as an existing defect with every changed path, value and digest effect, never as PASS and never as an unauthorized harness change; checks then resume from a new baseline after one tick. Add check_eq.py rules and negative tests as listed in the plan. Run the engine-free python3 test_eq.py until every existing test passes, save the raw output, update PROGRESS.md, and end S3b with formal status blocked and the finding 'stage S3b complete (not a failure; next is S4)'. Do not submit. No engine, no git write or commit, no product change, no full regression; SPEC, TASK, eq/references and eq/registration stay unchanged. Ordinary implementation choices are recorded without stopping; block only for undecided matters affecting original product spec, values, permissions, billing or original acceptance. The remaining order is S4 (driver and verify) and submission, then Root native on the exact S in 7 phases, then both validations, then a fresh independent Opus review of all 6 conditions, then the normal prepare, candidate qualification, approval, integration and final; the OPT whole-unit gate follows later. No original credit (23/88, 4/30); the 900-second timeout is unchanged. Quota fallback only on structured provider quota, once, same role, Antigravity claude-opus-5-5-high; any other failure is blocked. Decided by Claude Opus 5.5 in the Desktop control session (message 334); not a CLI commander result."}

+
+共通
+- 最初に eq/PROGRESS.md と eq/IMPLEMENTATION.md（末尾の S4 の結合の要件を含む）を読み、S1/S2/S3a の型・path・record schema・API・notes を再利用する。再設計しない。
+- E3、既存の91件の試験の本体、失敗の履歴は、消さない。書き直さない（失敗した試験が求める修正を除く）。
+- E4/E5 の操作は、SPEC §3.3 (b) の専用の scenario の区間でだけ行う。各区間には開始と終了の記録を付ける。check_eq.py の静的な許可は、この区間と、下に列挙した操作に限る。
+- 状態は全て r02 の A の typed tree で記録する（深さの制限なし、可逆）。正規化は r03 の閉じた一覧だけを使う。
+- 各操作について、前後の S/K/C 層の tree と、全イベントの差分と件数と、scenario の中で出た signal（測定の区間とは別の記録）を記録する。
+
+E4 キャッシュの古さ（R と O。5つの経路を、この順序で行う。各経路の後の状態を、次の経路の開始の状態として記録する）
+1. 状態を変えるコマンド（通常の command queue を通す）
+   - SimulationRuntime.submit_command(&"build_facility", {definition_id, origin, rotation})（autoload/simulation_runtime.gd:476、:305、:7717-7720）。
+   - 引数は固定の規則で選ぶ。定義の一覧（mvp_content_catalog）を ID の文字の順序で、cell を (x, y, z) の辞書順で走査し、製品の公開の配置の判定で、最初に配置できる組を選ぶ。選んだ規則と結果を記録する。施設の値を作らない。配置できる組が無い場合（たとえば O の小さな世界）は、理由つきの NA にする。
+   - 記録の時点: submit の直後（queue の状態、command の ID の counter）と、advance_minutes(1) を1回行った後（APPLY_COMMANDS で実行された後）。両方で、create_snapshot() と latest_snapshot の tree を記録する。
+2. tick: advance_minutes(1) を1回。直後の create_snapshot() と latest_snapshot を記録する。
+3. 直接の restore_snapshot(P)。P は、この経路の開始の時点の create_snapshot() の deep copy。
+   - 直後の S が、P を規則どおりに復元したものと、正規化の後で完全一致すること。
+   - SAVE_* の event は0件。
+4. load_from_path の成功
+   - この経路の開始の時点の snapshot を、SaveService.save_snapshot で、固定の user:// の path（例: user://p28_eq/<R|O>/e4_good）に、固定の metadata で保存する。save は静的な API で、Runtime の event を出さない。
+   - その path を、Runtime の load_from_path で読む。
+   - 直後の状態が X(P, ev_load) と、正規化の後で完全一致すること。SAVE_LOADED はちょうど1件。
+5. 状態を変えないコマンド（製品が検証の段階で拒否するコマンド）
+   - submit_command(&"build_facility", {definition_id: ""}) を submit して、advance_minutes(1) を1回行う。
+   - 戻り値と、command の結果（拒否の code）を記録する。
+   - 製品の状態の変化が、command の記帳（次の command の ID、処理済みの結果の記録）と tick の進行の分に限られることを、全ての path の差分で記録する。それ以外の変化があれば、事実として記録する。
+- 各経路の後に、create_snapshot() と latest_snapshot を記録する。latest_snapshot は publish（tick）の時にだけ更新される製品の仕様なので、tick を含まない経路の直後に latest_snapshot が以前の値のままであっても、それは記録する事実であって、cache の古さとは呼ばない。古さの判定は、OPT の後の版との、同じ場面での比較（compare_versions.py）で行う。
+- この段階での検査: 同じ版の2 PID の間で、5つの経路の記録が、正規化の後で一致すること（harness の決定性）。
+
+E5 所有権（R と O。4つの対象 × 入れ子の dict と配列 × 2つの向き）
+- 対象:
+  - (1) create_snapshot() の戻り値
+  - (2) SimulationRuntime.latest_snapshot
+  - (3) snapshot_published の引数
+  - (4) state_updated の引数
+  - (3) と (4) は、probe の既存の接続で受け取った参照を、handler の外で保持して使う。handler の中で変更しない（他の受け手への影響を避けるため）。
+- 変更の場所（固定。R と O の両方に存在するもの）:
+  - 入れ子の dict: systems.runtime.id_generator.counters に、key "__p28_eq_probe" と値 1 を追加する。
+  - 入れ子の配列: systems.runtime.domain_events.published_ids に、文字列 "__p28_eq_probe" を追加する。
+- 外から内:
+  - 変更の直前に、内部の create_snapshot() の tree と、latest_snapshot の tree と、latest_digest の文字列を記録する。latest_digest は遅延して計算されるので、変更の前に一度読んで確定させ、その事実を記録する。
+  - 変更の直後に、同じ3つを取り直して比べる。
+  - 変化があれば、変わった path と値を全て記録する。
+- 内から外:
+  - 返された値の deep copy を保持する。advance_minutes(1) を1回行った後に、返された値そのものが、保持した deep copy と同じであることを確かめる。
+- 予想される既存の不具合:
+  - latest_snapshot と、signal の引数 (3)(4) は同じ object である（:12617-12621）。そのため、(2)〜(4) の外から内の変更は、latest_snapshot を変え、まだ計算していない digest にも影響しうる。
+  - これは「既存の不具合」として、対象・向き・変わった path・値・digest への影響を全て記録する。PASS で補わない。harness による無断の変更とは区別する（どの scenario の、どの操作かを結びつける）。
+  - その後の検査は、advance_minutes(1) を1回行って新しい latest_snapshot が publish された後の状態を、新しい baseline として始める。
+- (1) が deep copy であれば、影響が無いことを予想する。影響があれば、同じく事実として記録する。
+
+check_eq.py と試験
+- E4 と E5 の記録の形式・必須の欄・矛盾の検査を加える:
+  - 経路の順序
+  - 区間の連続
+  - 件数（restore は0、load の成功は1）
+  - X(P, ev_load)
+  - 4×2×2 の全ての組の存在
+  - NA の理由
+- 拒否の試験を加える:
+  - 経路の欠落
+  - 件数の不一致
+  - 既存の aliasing を PASS として扱うこと
+  - aliasing の記録の欠落
+  - handler の中での変更
+  - 区間の外での状態の変更
+  - tick を含まない経路の latest_snapshot の据え置きを cache の古さと誤判定すること
+  - NA を PASS として数えること
+
+終わり
+- engine を使わない python3 test_eq.py の全件 PASS まで直し、生出力を保存する。PROGRESS.md を更新する。正式な JSON の status を blocked にし、findings を「段階 S3b 完了（失敗ではない。次は S4）」とする。提出しない。
+- engine の起動、git への書込み、製品の変更、全回帰はしない。通常の実装上の判断は、記録して進める。
