+# BAT-025 Design
+
+## D-1. Revision graph and parent
+
+구현 시작 직전 `uv run alembic heads` 및 `uv run alembic history`로 유효 head를 재확인한다. 신규 revision은 그 실제 head 하나를 `down_revision`으로 사용하며, 문서/코드에 20260628_0027을 선결 가정으로 고정하지 않는다.
+
+## D-2. Migration idempotency
+
+신규 revision은 inspector/information_schema 기반으로 table/column 존재를 확인한다.
+
+- `portfolio_ledger`가 정상적으로 존재하는 일반 경로에서는 네 컬럼을 추가한다.
+- runtime `ensure_schema()`가 이미 컬럼을 생성한 경로에서는 컬럼 재생성 없이 nullable/default를 검증·보정한다.
+- `source`는 upgrade 전에 NULL을 `'broker'`로 backfill하고 이후 `NOT NULL DEFAULT 'broker'`를 보장한다.
+- 기존 행은 삭제·재작성하지 않으며 upgrade 전후 row count와 business field를 비교한다.
+- down migration은 운영 forward-only 정책과 충돌하지 않도록 구현 범위를 명시하고, 운영 runbook은 column deletion을 rollback으로 제시하지 않는다.
+
+## D-3. Runtime boundary
+
+`app/repositories/postgres.py:ensure_schema()`는 bootstrap safety 경로로 유지한다. Alembic revision은 persistent schema history의 source of truth로 둔다. migration 성공만으로 version table을 임의 stamp하지 않으며, schema와 Alembic current가 함께 일치하는지 검증한다.
+
+## D-4. Test matrix
+
+| 시작 상태 | 검증 |
+| --- | --- |
+| fresh Alembic schema | upgrade, 네 컬럼 타입/nullable/default, current/head |
+| 기존 ledger rows | row count/business data 보존, source broker backfill |
+| runtime-precreated columns | 중복 DDL 부재, constraints/default 정합, current/head |
+| broker write | 기존 `/ledger/trades` 회귀 없음 |
+| manual API | source/manual metadata 및 REQ-056 핵심 regression |
+| runbook | preflight 조건, 실패 중단, forward-only recovery 문서 정합 |
+
+## D-5. Operational gate
+
+이번 batch는 local/non-production verification만 수행한다. 운영 DB backup/upgrade, service restart, 신규 API activation, deploy/push/merge는 M5 Release의 별도 결재 없이는 실행하지 않는다. runbook은 실행 가능한 명령 템플릿과 중단 조건을 제공하되 실제 운영 결과를 가장하지 않는다.
+
+## Design decisions / open findings
+
+- 실제 revision ID는 구현 preflight 결과로 결정한다.
+- 실제 DB driver availability에 따라 migration integration test harness는 repository 표준 fixture 또는 isolated PostgreSQL 경로를 사용하되, 사용하지 못한 환경은 QC evidence에 명시한다.
+- stamp 필요성은 schema inspection과 version table evidence 이후에만 판단하며 자동 조치하지 않는다.

+# BAT-025 Implementation Log
+
+- Date: 2026-07-15
+- Assignee: dev-impl
+- Scope: REQ-057 `portfolio_ledger` 수동 장부 메타데이터의 명시 Alembic migration
+- Implementation state: remediation complete; independent QC pending
+
+## Baseline and remediation provenance
+
+- Initial implementation baseline: `f6195ff8090d8761d467e15f44255642ca350e80`.
+- The previously recorded SHA `850e970` does **not** identify the reviewed implementation and is superseded by the baseline above.
+- The remediation is committed locally as `779d6f7711d700d6f56be22023cb826cc6f2fe28` on the isolated worktree branch. No push, PR, main merge, production migration, deployment, or service activation was performed.
+
+## Implemented changes
+
+1. Explicit revision `20260715_0028` remains the REQ-057 head.
+   - Parent: `20260628_0027`.
+   - Adds `source`, `target_ledger_entry_id`, `confirmation_evidence`, and `actor_user_id` additively.
+   - Handles runtime-precreated columns by backfilling nullable `source`, then converging its default and `NOT NULL` constraint.
+   - Downgrade remains a forward-only no-op; no column deletion was added.
+
+2. Remediation of actual PostgreSQL migration-chain/runtime behavior.
+   - `migrations/versions/20260605_0025_ledger_consolidation.py`: makes the identity `ledger_entry_id` explicitly `nullable=False`. PostgreSQL identity columns are implicitly non-null; the prior explicit trailing `NULL` was incompatible with fresh real-PostgreSQL migration.
+   - `app/db/migrations.py`: programmatic Alembic configuration now carries the caller-provided `Settings`. For a legacy/runtime-precreated schema, bootstrap stamps `20260628_0027` and then executes `upgrade head`, so revision `0028` performs its required source backfill/default/constraint convergence instead of being skipped by a direct head stamp.
+   - `migrations/env.py`: consumes the explicit settings when supplied and preserves existing application loggers when Alembic runs in-process.
+
+3. Real isolated PostgreSQL integration coverage.
+   - `tests/test_bat025_portfolio_ledger_manual_metadata_migration.py` creates a UUID-named temporary database only through an explicitly supplied loopback `postgres` maintenance DSN.
+   - The test rejects non-loopback hosts and any maintenance database other than `postgres`; each test terminates connections and drops only its own UUID-named database.
+   - Coverage includes pre-0028 upgrade/data preservation, runtime-precreated nullable `source` convergence and Alembic current-head state, plus representative broker/manual ledger writes after upgrade.
+
+4. Existing operation runbook is retained.
+   - `docs/runbooks/bat-025-req057-portfolio-ledger-manual-metadata-runbook.md`
+   - It remains a runbook only; no production command in it was executed.
+
+## Executed evidence
+
+All commands below used the local Docker PostgreSQL service only. The DSN was supplied from an environment variable and is intentionally omitted here.
+

+- `PYTHONPATH=. uv run --extra dev --with httpx2 python -m pytest -q --override-ini addopts='' -p no:cacheprovider`
+  - Result: **597 passed, 11 warnings in 41.41s**.

+- `uv run --extra dev ruff check app/db/migrations.py migrations/env.py migrations/versions/20260605_0025_ledger_consolidation.py tests/test_bat025_portfolio_ledger_manual_metadata_migration.py`

+- `python3 -m compileall -q app migrations` and `git diff --check`
+  - Result: exit 0.
+
+## Limits / non-claims
+
+- This evidence is for isolated local PostgreSQL only; it is not an operational DB upgrade.
+- Lock contention, backup restore, production access control, deployment, service activation, and M5 release remain unexecuted.
+- This log is developer evidence only. It does not mark BAT-025 verified or approved; independent QC remains required.

+## Summary
+
+REQ-056/BAT-024가 사용한 `portfolio_ledger` additive metadata 네 컬럼을 runtime `ensure_schema()` 자동 DDL에만 의존하지 않고 명시 Alembic revision으로 추적·검증한다. 기존 broker/manual 데이터 보존, runtime-precreated schema 호환성, 운영 migration runbook 및 독립 QC를 delivery 범위로 둔다.

+# BAT-025 Planning
+
+## Objective
+
+REQ-057의 명시 Alembic migration과 운영 runbook을 구현·검증한다. BAT-024의 API 계약과 Implemented 상태는 변경하지 않는다.
+
+## Delivery sequence
+
+1. **Preflight** — `uv run alembic heads`, `uv run alembic history`, revision graph 및 `ensure_schema()` DDL 소유 경계를 확인하고 실제 head를 evidence로 고정한다.
+2. **Migration** — 실제 head를 parent로 하는 신규 revision을 작성한다. fresh/기존/runtime-precreated schema에서 중복 DDL 없이 네 컬럼, source backfill, NOT NULL/default를 보장한다.
+3. **Runtime compatibility** — `ensure_schema()` 선행 생성 경로와 Alembic version tracking의 상호작용을 테스트한다. 임의 stamp는 schema/version evidence와 승인된 절차 없이 사용하지 않는다.
+4. **Regression tests** — 기존 broker ledger write, manual ledger API, row/data preservation, schema metadata/current 정합을 검증한다.
+5. **Runbook** — backup, current, schema/row count, active query/lock, upgrade, post-check, smoke, 실패 대응 및 forward-only recovery를 문서화하고 dry-run 검토한다.
+6. **Independent QC** — dev-qc가 committed diff를 직접 검토하고 표준 테스트 및 migration-focused 테스트를 재실행한다.
+
+## Work packets
+
+### WP-1: Batch artifacts (lead)
+
+- 이 문서와 `design.md`, `index.md`를 confirmed 상태로 작성한다.
+- `docs/batches/index.md`에 BAT-025를 `confirmed`로 등록한다.
+- local main에 docs-only commit을 남긴다.
+
+### WP-2: Implementation (dev-impl)
+
+- 신규 Alembic revision, 필요한 runtime compatibility 수정, tests, `docs/runbooks/` runbook을 작성한다.
+- implementation log와 실행 명령/결과를 기록하고 implementation commit을 반환한다.
+- 운영 DB나 서비스 activation은 실행하지 않는다.
+
+### WP-3: QC (dev-qc)
+
+- dev-impl committed diff와 문서/REQ 정합성을 독립 검토한다.
+- `uv run pytest` 및 가능한 migration-focused checks를 재실행한다.
+- blocker가 있으면 PASS가 아닌 명시적 finding으로 반환한다.
+
+## Acceptance evidence targets
+
+- AC-1: head/graph preflight 출력
+- AC-2~5: fresh/legacy/runtime-precreated schema upgrade와 source backfill/중복 오류 부재
+- AC-6: `alembic current`, information_schema, row count 결과
+- AC-7~9: runbook preflight/실패 대응/forward-only recovery 검토 evidence
+- AC-10: 운영 실행을 하지 않았다는 scope evidence 및 release gate 기록
+- AC-11: implementation + tests + QC committed evidence
+
+## Risks / blockers
+
+- local repository의 schema graph와 runtime-created schema가 서로 다른 시작 상태를 가질 수 있다.
+- `ensure_schema()`와 Alembic 양쪽 소유 경계 변경은 기존 broker flow 회귀 위험이 있다.
+- 실제 PostgreSQL 운영 DB evidence는 이번 batch 밖이며 M5 Release 승인 없이는 확보하지 않는다.

+## Acceptance mapping
+
+| REQ-057 acceptance area | Evidence | Result |
+| --- | --- | --- |
+| Explicit `0028` revision is the chain head | `alembic_version` queried in a throwaway PostgreSQL DB after upgrade | Pass — current revision `20260715_0028` |
+| Existing broker/manual business data survives upgrade | Real `20260628_0027 → head` upgrade after a representative pre-existing ledger row is inserted; row fields and metadata are asserted after upgrade | Pass |
+| `source` is backfilled/defaulted/not-null | Real upgrade asserts preserved row `source='broker'`; schema inspection checks text type, non-null constraint, and default | Pass |
+| Runtime-precreated metadata schema converges | Real test creates all four columns with nullable `source`, invokes bootstrap, and asserts source backfill/default/not-null plus `current=head` | Pass |
+| Representative broker/manual writes still work | Post-upgrade synthetic repository writes assert broker source and manual metadata fields | Pass |
+| Earlier fresh PostgreSQL chain can reach 0028 | `0025` identity-column PostgreSQL incompatibility corrected and exercised by fresh throwaway DB migration path | Pass |
+| API/manual-ledger regression | `tests/test_v1_portfolios_manual_ledger.py`, `tests/test_v1_portfolios_trades.py`, `tests/test_v1_portfolios_ledger.py` | Pass — 33 tests |
+| Whole-repository regression | pytest with project dev extra plus temporary TestClient dependency overlay | Pass — 597 tests, 11 warnings |
+| Lint/compile/diff hygiene | Ruff, compileall, `git diff --check` | Pass |
+
+## Executed commands and results
+

+  - **3 passed in 6.10s**.
+  - Each test creates and removes a UUID-named database on local loopback PostgreSQL; it refuses non-loopback hosts and non-`postgres` maintenance databases.
+- `PYTHONPATH=. uv run --extra dev --with httpx2 python -m pytest -q --override-ini addopts='' -p no:cacheprovider`
+  - **597 passed, 11 warnings in 41.41s**.
+  - Warnings are Starlette deprecations for `HTTP_422_UNPROCESSABLE_ENTITY`; they are not BAT-025 failures.
+- `uv run --extra dev ruff check app/db/migrations.py migrations/env.py migrations/versions/20260605_0025_ledger_consolidation.py tests/test_bat025_portfolio_ledger_manual_metadata_migration.py`
+  - **All checks passed**.
+- `python3 -m compileall -q app migrations` and `git diff --check`
+  - exit 0.
+
+## Evidence boundaries and blockers
+
+- The local container is an isolated test target, not a staging or production database.
+- No production backup/restore, lock-duration measurement under production load, migration run against an operational DB, deploy, or service activation was attempted.
+- The test command uses a transient `httpx2` overlay because this environment's resolved Starlette TestClient requires it while the project declares `httpx`; no dependency source change was made for this batch.
+- The initial independent QC reproduced the technical evidence but returned FAIL because the then-committed document described the remediation as uncommitted and its test run produced an untracked `uv.lock`. Follow-up commit `71a0312e1efb54772b94fd7de0d8add5943f05af` corrected provenance/hygiene only; independent re-QC inspected that committed diff and passed it.
+
+## PR #21 provenance reconciliation
+
+The delivery was implemented and initially verified on the isolated worktree chain. PR #21 was then assembled by cherry-picking that chain onto the confirmed local-main baseline, which created different commit IDs. The mappings are:
+
+| Original worktree commit | PR #21 commit | Purpose |
+|---|---|---|
+| `f6195ff8090d8761d467e15f44255642ca350e80` | `1909caa22ce3f7d271dfb619b9095f998d0566cc` | BAT-025 implementation |
+| `779d6f7711d700d6f56be22023cb826cc6f2fe28` | `d48279f7abdbabe1eb59a8d85703cf21f28d39d0` | PostgreSQL verification hardening |
+| `71a0312e1efb54772b94fd7de0d8add5943f05af` | `2f82251e57cfefacec3dd39c49bfe40d605fe145` | provenance/hygiene correction |
+| `da731b554a2cb7823100f32c85e8cab578e0ea36` | `5f8097947c1933f6b5eadeab94e5528680effc10` | lead confirmation state at PR creation |
+
+- `git diff --exit-code da731b55..5f809794` confirmed that the original verified worktree state and PR #21 initial head have identical file content.
+- Lead reproduction after the PR QC environment correction used the tracked local-test loopback defaults without exposing the DSN. The migration suite passed **3 passed in 6.16s**.
+- Cleanup verification targets only the fixture contract `portfolio_hub_bat025_<32 lowercase hex UUID>`; its catalog count was **0**. The separately existing `portfolio_hub_bat025_test` database does not match that generated-name contract and was not modified.
+
+## Gate result
+
+- Developer self-verification: **complete** on the original worktree remediation chain, with the PR #21 commit mapping above.
+- Initial independent QC: **FAIL** — documentation provenance and untracked `uv.lock` hygiene only; technical ACs reproduced.
+- Original-worktree independent re-QC: **PASS** (`deleg_6b805aa0`, 2026-07-15), including loopback PostgreSQL and direct Ruff evidence.
+- PR #21 committed-diff QC: **PASS** (`deleg_ae0c6f27`, 2026-07-15). It verified the cherry-pick patch-id mapping, PR head `bd51330`, migration semantics, loopback PostgreSQL suite (**3 passed**), fixture-generated UUID catalog cleanup (**0**), direct Ruff checks, clean tested worktree, and PR diff hygiene.
+- `confirm-batch-verification`: **PASS accepted by TREX lead (2026-07-15)**. This approval is limited to merging the verified PR; it does not authorize release, deployment, operational database migration, or service restart.
+- M5 Release: **not started**. Release preparation requires separate scope/approval after merge; production migration requires a separate operational decision and release approval.

+#### Change Summary
+- 운영 적용 방식 보완을 REQ-057로 분리 추적한다. REQ-056의 기존 API 계약, AC-1~19, `Implemented` status 및 BAT-024 `release-candidate` 상태는 변경하거나 되돌리지 않는다.
+
+#### Intent
+- REQ-056 구현에서 사용된 additive `portfolio_ledger` 컬럼의 운영 DB 적용을 runtime `ensure_schema()` 자동 DDL에만 의존하지 않도록 명시 Alembic migration과 운영 runbook 요구사항으로 후속 관리한다.

+# REQ-057: portfolio_ledger 수동 장부 메타데이터 명시 Alembic 마이그레이션
+
+- Status: Approved
+- Type: Migration
+- Priority: High
+- Owner: Justin Ko
+
+## Intent
+
+- REQ-056 수동 장부 API가 사용하는 `portfolio_ledger`의 additive 메타데이터 컬럼을 runtime `ensure_schema()` 자동 DDL에만 의존하지 않고, 추적 가능한 명시적 Alembic revision으로 운영 적용 가능하게 한다.
+- 운영 DB 스키마와 Alembic revision 상태를 일치시키고, migration 검증 전에는 해당 신규 API 코드를 활성화하지 않는 배포 선행조건을 정의한다.
+
+## Requirement
+
+- `portfolio_ledger`에 아래 네 컬럼을 적용하는 신규 Alembic revision을 작성한다.
+
+  | 컬럼 | SQL 타입 | NULL 정책 | 기본값/의미 |
+  | --- | --- | --- | --- |
+  | `source` | `TEXT` | `NOT NULL` | `DEFAULT 'broker'`; broker 기존 행과 broker write의 출처 |
+  | `target_ledger_entry_id` | `BIGINT` | `NULL` 허용 | `REVERSAL` target ledger entry 참조 |
+  | `confirmation_evidence` | `TEXT` | `NULL` 허용 | daemon-managed manual write의 명시적 확인 근거 |
+  | `actor_user_id` | `TEXT` | `NULL` 허용 | manual write를 수행한 사용자 추적 값 |
+
+- revision의 `down_revision`은 구현 시점에 repository의 실제 Alembic head를 `alembic heads` 및 migration graph로 사전 확인하여 결정한다. 요구사항 문서에서 특정 revision ID를 하드코드 전제로 단정하지 않는다.
+- upgrade는 기존 `portfolio_ledger` 행을 삭제·재작성하지 않고 보존해야 하며, 기존 행과 `source`가 비어 있는 선행 상태의 행은 `source='broker'`를 만족하도록 처리한 뒤 `source NOT NULL DEFAULT 'broker'`를 보장해야 한다.
+- runtime `ensure_schema()` 자동 DDL로 위 컬럼이 이미 선행 생성된 DB에서도 migration이 안전하게 완료되어야 한다. 구현은 컬럼/제약 존재 여부, 기존 행의 `source` 값, Alembic version table을 확인해 중복 DDL 오류 없이 revision을 적용 또는 필요한 상태 정합 절차를 수행해야 한다.
+- migration 완료 후 `alembic current`가 구현 시 확정한 revision/head와 일치해야 한다. 스키마만 존재하고 Alembic revision이 불일치한 상태는 완료로 간주하지 않는다.
+- 이 migration의 검증 완료는 운영 배포에서 REQ-056 신규 manual ledger API 코드를 활성화하기 위한 선행조건이다. 서비스 재시작·신규 코드 활성화는 migration upgrade와 schema/current 검증이 성공한 뒤에만 허용한다.
+- 운영 runbook을 작성한다. runbook은 최소한 백업, `alembic current`, 대상 테이블 schema/row count, 활성 쿼리·lock 확인, upgrade, schema/current 재검증, service smoke, 실패 대응을 포함해야 한다.
+- rollback은 code rollback + additive schema 유지의 forward-only 정책으로 정의한다. 운영 환경에서 down migration 또는 컬럼 삭제를 자동 rollback 경로로 사용하지 않는다.
+- 운영 DB 실행은 이 REQ/BAT 범위에 포함하지 않는다. 실제 upgrade·서비스 활성화는 증적 검토 후 별도 명시 release 결재가 있어야 한다.
+- migration implementation, test, 독립 QC 및 batch verification은 표준 배치 `BAT-025`에서 수행한다. 이 REQ 초안에서는 BAT-025 batch artifact 또는 migration/code 파일을 생성하지 않는다.
+
+## Acceptance Criteria
+
+1. Given implementation preflight, When Alembic migration을 생성하기 전 `alembic heads`와 revision graph를 확인하면, Then 실제 단일/유효 head를 근거로 신규 revision의 `down_revision`을 결정하며 REQ 본문에 특정 기존 revision ID를 선결 조건으로 하드코드하지 않는다.
+2. Given migration이 적용되지 않은 DB의 `portfolio_ledger`, When 신규 revision을 upgrade하면, Then `source TEXT NOT NULL DEFAULT 'broker'`, `target_ledger_entry_id BIGINT NULL`, `confirmation_evidence TEXT NULL`, `actor_user_id TEXT NULL` 네 컬럼이 모두 존재한다.
+3. Given upgrade 전 기존 `portfolio_ledger` 행이 존재하면, When 신규 revision을 upgrade하면, Then 기존 행 수와 기존 business data가 보존되고 모든 기존 행의 `source`는 `'broker'`이다.
+4. Given 기존 행 또는 runtime 선행 DDL 상태에서 `source`가 NULL 또는 미설정이면, When migration이 완료되면, Then NULL `source`가 남지 않고 `source`는 `'broker'`로 backfill되며 이후 컬럼은 `NOT NULL DEFAULT 'broker'` 제약을 만족한다.
+5. Given runtime `ensure_schema()`가 네 컬럼을 이미 생성한 DB, When Alembic migration을 적용하면, Then 중복 컬럼/제약 오류 없이 안전하게 완료되고 schema와 Alembic version 상태가 revision/head와 일치한다.
+6. Given migration upgrade가 완료되면, When `alembic current`와 information schema/row count 검증을 실행하면, Then current revision은 구현 시 확정한 head이고 네 컬럼의 타입·nullable/default 및 row count 보존 결과가 기대값과 일치한다.
+7. Given migration 전 preflight, When 운영 runbook을 수행하면, Then DB backup 성공, `alembic current` 기록, `portfolio_ledger` schema/row count 기록, 대상 테이블 활성 쿼리·lock 부재 또는 승인된 maintenance window가 모두 확인되지 않으면 upgrade 전에 중단한다.
+8. Given upgrade와 사후 schema/current 검증이 성공하면, When 서비스 smoke를 실행하면, Then DB-enabled health와 REQ-056 manual ledger API의 승인된 non-production/운영 smoke 시나리오가 성공한다. migration 검증 실패 시 신규 API 코드 활성화 또는 서비스 재시작을 진행하지 않는다.
+9. Given migration 또는 service smoke 이후 코드 문제가 발생하면, When rollback 판단을 내리면, Then 직전 호환 코드로만 rollback하고 적용된 네 additive 컬럼과 Alembic revision은 유지하는 forward-only 복구 정책을 따른다. 운영 down migration/컬럼 삭제는 자동 조치가 아니다.
+10. Given 운영 DB 적용을 요청할 때, When 별도 release 결재가 없으면, Then 실제 DB upgrade, 서비스 재시작, 신규 API 활성화를 실행하지 않는다.
+11. Given `BAT-025` delivery, When implementation/test/QC를 완료하면, Then Alembic upgrade 및 runtime-precreated-schema 호환성, data preservation, runbook dry-run/검증, 기존 broker ledger 흐름 회귀를 evidence로 기록하고 독립 QC를 거친다.
+
+## Impacted Area
+
+- Docs:
+  - `docs/runbooks/` — BAT-025 운영 migration runbook 신규 작성 예정.
+  - `docs/data-model.md` — `portfolio_ledger` 컬럼과 revision 기록 갱신 예정.
+  - `docs/releases/` — 운영 적용 시 별도 release 결재와 실행 증적 기록 예정.
+- Modules:
+  - `migrations/versions/` — 네 컬럼을 위한 신규 Alembic revision 예정.
+  - `app/repositories/postgres.py` 또는 `ensure_schema()` 소유 모듈 — runtime 자동 DDL과 Alembic migration의 idempotent 호환성 검증/보강 예정.
+  - migration bootstrap/CLI 경로 — `alembic current` 및 upgrade 사전·사후 검증 경로 확인 예정.
+- Tests:
+  - fresh/upgraded DB schema, 기존 행 보존과 `source='broker'` backfill 검증.
+  - runtime-precreated-schema → Alembic upgrade → current/head 정합 integration 검증.
+  - 기존 broker ledger write 및 REQ-056 manual ledger smoke/regression 검증.
+  - runbook preflight/forward-only recovery 절차의 문서 검증.
+
+## Notes
+
+- Source: REQ-056 Implementation Confirmation 및 `docs/srs/index.md` 2026-07-14 release caveat. REQ-056은 이미 Implemented/BAT-024 release-candidate이므로 본 REQ는 REQ-056 AC 또는 status를 되돌리지 않고 운영 적용 방식만 별도 추적한다.
+- Repository 기록에는 과거 Alembic head로 보이는 revision이 있으나, 새 migration의 parent는 구현 착수 시점의 실제 head로 재검증해야 한다.
+- 기존 runtime `ensure_schema()` 자동 DDL은 선행 스키마 생성 가능성을 만들 수 있으므로, 그 DB에서도 Alembic revision 추적을 회복·일치시키는 것이 핵심이다. 임의 `stamp` 여부와 조건은 BAT-025 design/implementation에서 실제 schema와 migration graph 증거로 결정한다.
+- 운영 DB 실행, 배포, 서비스 재시작, commit/push는 이번 요구사항 초안 범위에 포함하지 않는다.
