 # Anti-noise rules
 
-git is the source of truth for what happened to files, branches, commits, tickets, and worktrees. Memory must NOT shadow it.
+Authoritative project records (issue trackers, task boards, planning documents, changelogs, version-control history, generated reports) are the source of truth for their exact contents. Memory must not mirror those records verbatim or maintain a parallel status ledger, but it may capture durable project-management facts, workflow constraints, recurring patterns, and abstractions when they will help future work.
 
-- `attempts`: skip any action whose substance is a git-trackable operation — creating / editing a ticket file, adding a TODO entry, opening a branch / worktree, running `commit` / `merge` / `push`, spawning a worker Pod for a known ticket. The corresponding diff / commit log already records it. Keep `attempts` for things that are NOT recoverable from git: build / test outcomes, external API responses, observed bug reproductions, design experiments whose results inform later judgement.
-- `discussions`: skip transient triage that goes stale within the day — "which ticket to start next", "should we review now or later", checklist-style status reads. Keep discussions whose points outlive the session (architectural trade-offs, durable constraints, recurring questions).
-- `decisions`: the rationale must be a design / policy / approach reason, not "we did X in this session". Recording "a ticket was created for Y" or "implementation landed as commit Z" is NOT a decision — those belong to git, not memory.
-- Do not embed identifiers that age out of relevance: commit hashes, branch names, worktree paths, ticket file names, PR numbers. If a record is only meaningful with such an identifier, the record itself is probably session-local and should be skipped.
+- `attempts`: skip actions whose only substance is maintaining an authoritative record or moving an item through an external lifecycle. Keep attempts for outcomes that are not captured by that record itself: build / test outcomes, external API responses, observed bug reproductions, design experiments, and process lessons that inform later judgement.
+- `discussions`: skip transient triage that goes stale within the day — immediate scheduling, checklist-style status reads, or short-lived sequencing choices. Keep discussions whose points outlive the session (architectural trade-offs, durable process constraints, recurring workflow questions).
+- `decisions`: the rationale must be a design / policy / process / approach reason, not "we did X in this session". Recording that an item was filed, completed, or moved through a lifecycle is NOT a decision; recording the durable policy or abstraction behind that workflow can be.
+- Avoid copying titles, bodies, checklists, raw statuses, or short-lived identifiers from authoritative project records. If a record is only meaningful as an exact status mirror or with a transient identifier, the record itself is probably session-local and should be skipped.

+# Review: Memory prompts: project-specific ticket shadow policy を外す
+
+## 前提・要件の確認
+
+- bundled memory prompts から ticket / TODO 固有の shadow 禁止を削除: OK。Phase 1 prompt は ticket / TODO / worktree / branch / commit 等の列挙を消し、authoritative project records 一般へ置き換えている（`.worktree/memory-prompts-remove-ticket-policy/resources/prompts/internal/memory_extract_system.md:27-32`）。Phase 2 prompt も `git is authoritative` と ticket/TODO 固有列挙を削除し、issue trackers / task boards / planning documents 等の一般表現へ置換している（`.worktree/memory-prompts-remove-ticket-policy/resources/prompts/internal/memory_consolidation_system.md:21-22`）。
+- `git is authoritative` の扱いを一般ユーザー向けに弱める: OK。正確な内容の authoritative record を memory が mirror しないという原則は残しつつ、durable project-management facts / workflow constraints / prioritisation rationale / process decisions / cross-item lessons は保存可能と明示している（`memory_extract_system.md:27-32`, `memory_consolidation_system.md:22`）。
+- Phase 1 / Phase 2 の整合: OK。Phase 1 の抽出除外条件と Phase 2 の統合時ルールがどちらも「raw status ledger は作らないが、持続的な抽象は採用可」という同じ方針になっている（`memory_extract_system.md:29-32`, `memory_consolidation_system.md:22`）。
+- default prompt が特定 project-management 手法を前提にしないことの文書化: OK。`docs/plan/memory-prompts.md` の共通原則に「特定の project-management 手法を前提にしない」が追加され、ticket / TODO 固有の旧記述が一般化されている（`.worktree/memory-prompts-remove-ticket-policy/docs/plan/memory-prompts.md:19-20`）。
+- 既存テスト / prompt catalog 検査: OK。`cargo test -p pod prompt::catalog` を実行し、11 tests passed。
+
+## アーキテクチャ・スコープ
+
+- 変更は bundled prompt 2 件と plan doc 1 件のみで、memory の file format / linter / Phase 1 / Phase 2 実行機構には触れていない。ticket の範囲外を守っている。
+- prompt 文言の責務分離は妥当。INSOMNIA 固有の ticket shadow 回避を default prompt から外し、workspace / user prompt override 側へ逃がせる状態にしている。
+- `docs/plan/memory-prompts.md` も同時に更新しており、実装 prompt と計画文書が乖離していない。
+
+## 指摘事項
+
+### Blocking
+
+なし。
+
+### Non-blocking / Follow-up
+
+なし。
+
+### Nits
+
+- `docs/plan/memory-prompts.md:68` に「git で可逆」という表現が残っているが、これは tidy phase の drop 判断に関する一般的な VCS 可逆性の話で、ticket / TODO 固有の shadow policy ではないため本チケットの完了を妨げない。
+
+## 判断
+
+Approve — ticket / TODO 固有の bundled prompt 方針は削除され、一般的な authoritative record 非重複方針へ置き換わっている。変更範囲も prompt / plan に限定され、既存 prompt catalog tests も通っている。
