+# Ledger outbox instance ownership and lease fencing
+
+## Criterion
+
+`trex-core`의 durable ledger outbox row는 enqueue 시점의 required non-empty `instance_key`를 immutable owner로 저장해야 하며, daemon·operator backfill·targeted processing을 포함한 모든 delivery 경로는 자기 instance의 row만 claim하고 처리해야 한다. Shared PostgreSQL에서 claim은 pending·retry-due·unclaimed 또는 lease-expired row를 원자적으로 선택해 worker별 bounded lease를 설정해야 하고, 성공·중복·retryable·conflict·permanent·dead-letter outcome은 해당 claim의 fencing 정보가 일치할 때만 반영해야 한다. 다른 instance, legacy `instance_key IS NULL`, 아직 유효한 foreign lease 또는 이미 새 worker가 reclaim한 row는 처리·상태 변경·성공 통계·ledger-skip resolution 없이 fail closed 해야 한다.
+
+Claim owner가 crash하면 lease 만료 후 같은 instance의 다른 worker가 row를 reclaim할 수 있어야 한다. Outcome CAS가 0건이면 claim 상실로 명시적으로 처리하고 성공 outcome으로 보고해서는 안 된다. InMemory와 PostgreSQL outbox는 instance filtering, active lease exclusion, expiry recovery와 stale-claim rejection에서 같은 의미를 가져야 한다. Claim·outcome 관측 정보에는 `instance_key`, sanitized result/reason과 correlation identity만 허용하며 credential, account identifier, token, password, DSN, provider payload 또는 exception 원문을 로그·metric·alert에 포함해서는 안 된다.
+
+## Verification
+
+- 격리 조건: 서로 다른 `instance_key`의 daemon/writer 두 개가 한 PostgreSQL을 공유할 때 각 writer는 자기 row만 claim·전송·집계한다. `list_pending`, `pending_cash_delta`, batch claim과 correlation-targeted claim 모두 foreign row와 `instance_key IS NULL` legacy row를 제외한다. 누락·빈 instance key로 outbox 또는 writer를 생성하면 외부 연결이나 row 생성 전에 거부된다.
+- lease 조건: worker A가 claim한 row는 lease 동안 worker B가 claim하지 못한다. A가 outcome을 기록하면 lease가 해제되고 terminal 또는 retry 상태가 정확히 저장된다. A가 crash한 경우 expiry 전에는 B가 claim하지 못하고 expiry 뒤에는 B가 reclaim할 수 있다. Reclaim 뒤 A의 stale outcome은 typed claim-lost 결과로 거부되며 B의 row 상태, outcome, attempt count, next retry와 lease를 변경하지 않는다.
+- outcome 조건: adapter의 신규 성공과 `DUPLICATE_OK`, retryable, conflict, permanent 및 dead-letter 모든 분기는 claim fencing을 전달한다. CAS 실패 시 completion/retry counter, 성공 로그, snapshot write-back 이후의 ledger-skip resolution을 실행하지 않는다. Adapter duplicate는 row를 `completed/duplicate_completed`로 만들고 lease를 즉시 해제하여 재전송되지 않는다.
+- InMemory parity: 두 번의 동시 claim에서 첫 claim만 성공하고 active lease row는 pending scan에서 제외된다. clock을 이동하면 expiry recovery가 가능하며 이전 claim token으로 outcome을 기록할 수 없다. Instance filter와 targeted processing의 fail-closed 동작이 PostgreSQL과 같다.
+- 보안 조건: exception에 credential·account·token·password·DSN·provider payload를 식별하는 sentinel을 넣어 claim 실패, retry, permanent, dead-letter와 write-back 오류를 실행해도 rendered log, metric key/value와 alert에 sentinel 또는 exception 원문이 나타나지 않는다.
+- migration 및 회귀: migration 번호는 저장소에서 유일하고 기존 row를 자동 귀속시키지 않으며 `instance_key IS NULL`로 격리한다. 빈 DB와 기존 schema 모두에서 migration apply/replay, PostgreSQL claim round-trip, restart/expiry 회수, daemon·CLI wiring을 검증한다. 전체 repository test, Ruff, compileall, ProofLine validation과 `git diff --check`를 실행한다.

+# Unmanaged position durable lifecycle, authority fencing, and operator audit
+
+## Criterion
+
+`trex-core`는 broker 계정에 존재하지만 대상 instance의 managed slot/ledger가 소유하지 않는 종목을 `(instance_key, symbol)` 단위의 durable unmanaged-position lifecycle로 추적해야 한다. Lifecycle state는 instance 간에 섞이지 않아야 하며, 최소 `detected`, `quantity_changed`, `resolved`, `reopened` 전이와 `first_seen_at`, `last_seen_at`, `quantity_changed_at`, `resolved_at` 보존을 제공해야 한다. 같은 수량의 반복 authoritative 관측은 `last_seen_at`만 갱신하고 lifecycle audit/alarm을 다시 만들지 않아야 한다.
+
+absence resolution은 explicit authoritative full-balance snapshot에서만 허용되며 projected/partial/non-authoritative broker view 또는 broker read failure는 resolve authority가 아니다. observe와 resolve는 reconcile pass 전체에 전달된 동일 snapshot timestamp 또는 monotonic generation으로 fenced 되어야 하며 stale observe/stale resolve는 더 최신 state나 audit를 reopen, overwrite 또는 resolved 처리하지 못해야 한다. 최종 state와 append-only audit는 항상 가장 최신 authoritative snapshot이 결정해야 한다.
+
+운영자 disposition은 explicit evidence reference가 있는 명령으로만 기록되고 inspectable append-only audit trail에 남아야 한다. 이 기능은 broker order submit/cancel, slot 생성·상태 변경, synthetic ledger mutation 또는 warning 자동 삭제를 수행해서는 안 된다.
+
+## Verification
+
+- identity/lifecycle: 같은 symbol을 서로 다른 `instance_key`에서 독립 state로 저장하고 first detect, quantity change, resolved, resolved 뒤 reopened, first/last-seen 보존을 InMemory/PostgreSQL parity로 검증한다.
+- authority boundary: missing marker, `False`, ownership/projected broker, partial reader, broker read failure에서는 absence resolution이 발생하지 않고 explicit authoritative full-balance snapshot에서만 resolved가 기록됨을 검증한다.
+- temporal fencing: 더 오래된 absent snapshot이 더 최신 observe 뒤늦게 commit 되어도 resolved 되지 않고, 더 오래된 observe가 더 최신 resolved/observe를 reopen 또는 overwrite하지 않으며 final state/audit가 최신 authoritative snapshot 순서를 따른다는 PostgreSQL concurrency/interleaving 회귀를 검증한다.
+- suppression/audit: 같은 수량 반복 관측은 duplicate lifecycle alarm/audit를 만들지 않고 `last_seen_at`만 갱신한다. operator `record`는 `evidence_ref`를 요구하고 `unmanaged audit`로 append-only history를 조회할 수 있어야 한다.
+- safety boundary: unmanaged lifecycle path가 broker order, slot mutation, ledger write 또는 warning auto-clear를 수행하지 않음을 existing regression surface와 focused tests로 유지한다.

+4. Ownership projection이 켜진 mixed-account KIS 경로에서는 주문/전략 조회용 broker가 strategy-owned quantity만 보이도록 balance를 투영할 수 있다. 이때 unmanaged reconciliation은 provider가 별도로 넘기는 authoritative full-balance reader를 사용한다. Missing authority marker, projected/partial reader, self-report failure 또는 balance read failure는 absence resolution authority가 아니며 active unmanaged row를 `resolved`로 바꾸지 않는다.
