+Extract staging の entry-level source anchors / evidence references を実装・レビュー・merge・検証した。
+
+実装内容:
+- `crates/memory/src/schema/common.rs` に bounded source/evidence metadata 型を追加。
+  - `EvidenceKind(pub String)`。
+  - known constants: `message`, `tool_call`, `tool_result`, `file_ref`, `ticket_ref`, `objective_ref`。
+  - `SourceEvidenceRef` with `session_id`, `segment_id`, `entry_range`, `evidence_id`, `evidence_kind`, `label`, `summary`。
+- `DecisionEntry`, `DiscussionEntry`, `AttemptEntry`, `RequestEntry` に optional `source_refs: Vec<SourceEvidenceRef>` を追加。
+- `source_refs` は default empty / skip serializing empty とし、`#[schemars(skip)]` で LLM extract schema には露出しないようにした。
+- 既存 `StagingRecord.source` は record-level source range として維持。
+- old staging JSON without `source_refs` の互換性を維持。
+- legacy record-level `source.session_id` compatibility を追加。
+- new staging JSON with entry-level refs の roundtrip を追加。
+- consolidation input は pretty JSON として entry-level refs を lossless に保持するようにした。
+- session-explore / resolver tools / extract launch / staging resolution/disposition はこの Ticket では実装していない。
+
+Review:
+- Reviewer approved with no blockers。
+- Evidence included bounded anchor field definitions, all four entry types, old/new JSON tests, legacy source compatibility, and consolidation preservation。
+- Non-blocking note: `label` / `summary` の length/raw-content discipline は type enforcement ではなく semantic/host-policy に残る。
+
+Merge / validation:
+- Merge commit: `9a1a75de merge: staging source anchors`。
+- Final validation passed:
+  - `cargo fmt --check`
+  - `git diff --check`
+  - `cargo test -p memory`
+  - `cargo check -p yoi`
+  - `yoi ticket doctor`
+  - `nix build .#yoi --no-link`
+- Validation log: `/run/user/1000/yoi/yoi-orchestrator/bash-output/staging-source-anchors-final-validation-1784231070.txt`
+
+Cleanup:
+- Implementation worktree/branch cleanup will be performed after close commit。
+- Per user instruction, `StopPod` is not used。

+## Implementation report
+
+Merge / final validation report:
+
+- Reviewer approved the implementation with no blockers。
+- Merged branch `work/00001KXNYXNM6-staging-source-anchors` into orchestration branch with merge commit `9a1a75de merge: staging source anchors`。
+- Final validation was rerun in `/home/hare/Projects/yoi/.worktree/orchestration` after merge。
+
+Validation passed:
+- `cargo fmt --check`
+- `git diff --check`
+- `cargo test -p memory`
+- `cargo check -p yoi`
+- `yoi ticket doctor`
+- `nix build .#yoi --no-link`

+Validation log:
+- `/run/user/1000/yoi/yoi-orchestrator/bash-output/staging-source-anchors-final-validation-1784231070.txt`
+
+Reviewed/merged implementation commit:
+- `31798fb2 feat: add staging entry source anchors`
+
+Notes:
+- `StagingRecord.source` remains the record-level source range。
+- Entry-level `source_refs` are optional, default empty, and skipped when empty。
+- Old staging JSON compatibility and new source-ref roundtrip are covered by tests。
+- Consolidation input preserves entry-level refs as pretty JSON。
+- session-explore / resolver tools / extract launch / staging resolution were not implemented in this Ticket。
+- Per user instruction, no `StopPod` cleanup was performed。
