Decision

ユーザー指示により、設計で止める Ticket ではなく実装 Ticket として再スコープした。Overview-first extract / evidence tools は実装要件に変更し、staging 審査・剪定も resolution/disposition の実装まで含める。

---

Decision

実装者が対象領域と意図を追いやすいように、実装意図、対象 module、実装方針、想定順序を item.md に追記した。特に extract/input.rs、extract/tool.rs、extract/payload.rs、extract/staging.rs、worker.rs、memory_extract_system.md を主な対象として明示し、初期 evidence tools は extract slice 内の bounded read-only search/read/anchor 解決に閉じる方針を示した。

Decision

Rescoped from broad Overview-first extract implementation to the worker implementation slice. This Ticket now implements an extract worker that runs with only the builtin:session-explore feature enabled, connected to an immutable conversation snapshot and filtered Overview projection. It depends on Ticket 00001KXNYXNM6 for the staging source anchor / evidence ref format.

---

Decision

Design updated: abandon the old batch write_extracted / decisions / discussions / attempts / requests staging direction. Extract now stages flat candidate records with stage_candidate and finishes with finish_extraction. The older dependency on 00001KXNYXNM6 is historical; the active schema dependency is 00001KXRM6G0G.

Implementation report

Implemented the session-explore-backed memory extract worker.

Changes:

• Added builtin:session-explore with search_evidence, read_evidence, stage_candidate, and finish_extraction.
• Extract worker now builds an immutable SessionReferenceView at extract start and enables only session-explore tools for the internal worker.
• Added overview-first / evidence-index-second extract input rendering over the reference view.
• stage_candidate writes one flat staging record per call, resolving evidence ids into bounded staging evidence and SourceEvidenceRef anchors.
• finish_extraction supports normal no-candidate completion with staged_count = 0.
• Updated memory_extract_system.md to the session-explore / stage / finish contract.
• Added a single-candidate staging helper in memory::extract::staging.
• Updated extract-trigger tests to use finish_extraction and added session-explore unit tests.

Validation:

• cargo fmt --check
• cargo test -p worker
• cargo test -p memory
• nix build .#yoi
• yoi ticket doctor

完了

Implemented the session-explore-backed extract worker.

The extract worker now receives an immutable SessionReferenceView snapshot and only the builtin:session-explore tool surface. It can search/read bounded evidence, stage one flat candidate per stage_candidate call with resolved source anchors, and finish cleanly with finish_extraction including the no-candidate path.

Validation passed:

• cargo fmt --check
• cargo test -p worker
• cargo test -p memory
• nix build .#yoi
• yoi ticket doctor
