Subject: [PATCH 1/8] fix(ci): add Postgres service container to backend job,
 close fresh-install migration gap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

backend job in app-ci.yml had no `services:` block, so every
@pytest.mark.postgres real-Postgres test connected to nothing and always
silently pytest.skip'd — nobody knew this ecosystem-wide until it was run
for real. Adds a pgvector/pgvector:pg16 service (test/test/test_db,
pg_isready healthcheck) with a matching DATABASE_URL, matching
tests/conftest.py's existing default.

Running the suite for real against local PostgreSQL 16 + pgvector surfaced
3 more latent bugs beyond the CI wiring itself:

- 0011_email_read_state still hardcoded the pre-rename legacy `emails`
  table (`op.add_column("emails", "is_read", ...)`), so `alembic upgrade
  head` against a genuinely fresh database crashed with
  `relation "emails" does not exist` even after bootstrap_db.py's existing
  legacy-index statement was guarded. email_records (the current ORM
  table) already has is_read, so a fresh install needs this migration to
  be a no-op; guarded it the same way, behind
  sa.inspect(...).has_table("emails").
- Raw SQL INSERT INTO email_records in test_bootstrap_db.py and
  test_data_api.py omitted is_read (Python-side ORM default only, no DB
  server default), so real Postgres rejected them with
  NotNullViolationError. Filled it in explicitly at all 4 call sites.
- test_bootstrap_db.py's local _execute_schema_backfill test helper
  duplicated the old unguarded backfill loop instead of using the new
  scripts.bootstrap_db.execute_schema_backfill; pointed it at the real
  guarded function instead.

Verified against real PostgreSQL 16 + pgvector: full backend suite 1837
passed / 2 skipped (unrelated LIVE_BASE_URL live-API smoke), ruff clean,
`alembic upgrade head` and scripts/bootstrap_db.py both idempotent against
a fresh database. Documented the new hard CI gate in CLAUDE.md and
AGENTS.md so it isn't assumed best-effort going forward.

Closes the follow-up tracked in ContextualWisdomLab/.github's
docs/product-technical-gap-baseline.md (2026-09-01 entry).

 ## [Unreleased]
+- **(CI 인프라, 🔴 critical) `backend` job에 Postgres 서비스 컨테이너가 없어 `@pytest.mark.postgres`
+  real-Postgres 테스트가 CI에서 단 한 번도 실제로 실행되지 않고 항상 조용히 skip되던 문제를
+  고쳤습니다.** `.github/workflows/app-ci.yml`의 `backend` job에 `pgvector/pgvector:pg16`
+  서비스 컨테이너(`test`/`test`/`test_db`, `pg_isready` 헬스체크)를 추가하고 `DATABASE_URL`을
+  같은 자격증명으로 설정해, `tests/conftest.py`의 기본값과 그대로 맞물리도록 했습니다. 실제로
+  CI 환경과 동일하게(로컬 PostgreSQL 16 + pgvector) 처음 돌려보자 다음 3개의 실재 결함이 추가로
+  드러났습니다.
+  1. **`0001_initial_control_plane`뿐 아니라 `0011_email_read_state`도 완전히 새 데이터베이스에
+     대한 `alembic upgrade head`를 깨뜨렸다.** `backend/scripts/bootstrap_db.py`의
+     `ix_emails_owner_date` 인덱스 생성문(레거시 `emails` 테이블 대상)을 식별자로 삼아 건너뛰는
+     `execute_schema_backfill()`을 추가해 0001에서 쓰도록 했지만, `0011_email_read_state.py`가
+     같은 레거시 `emails` 테이블에 `op.add_column("emails", "is_read", ...)`을 직접 실행해
+     `relation "emails" does not exist`로 여전히 실패했습니다 — `email_records`(현재 ORM
+     모델)에는 `is_read`가 이미 있으므로, 신선한 설치에서는 이 마이그레이션이 전혀 필요하지
+     않습니다. `sa.inspect(op.get_bind()).has_table("emails")`가 거짓이면 no-op하도록 가드.
+     두 수정 모두 완전히 새 데이터베이스에 대해 실제로 `alembic upgrade head`를 실행해 진짜
+     RED(각각 `relation "emails" does not exist`)를 확인한 뒤 고쳤습니다(진짜 GREEN, 단일 head
+     `0017_merge_newsdom_carddav_heads`까지 재현).
+  2. **`tests/test_bootstrap_db.py`와 `tests/test_data_api.py`의 raw SQL `INSERT INTO
+     email_records`가 `is_read`(ORM 쪽 Python-side `default=True`, DB 서버측 default 없음)를
+     빠뜨려 real Postgres에서 `NotNullViolationError`로 하드 실패했습니다.** 두 파일의 4개
+     INSERT문 모두에 `is_read`를 명시적으로 채우도록 수정. `test_bootstrap_db.py`의 로컬 헬퍼
+     `_execute_schema_backfill`이 가드 없는 예전 루프를 그대로 복제하고 있던 것도
+     `scripts.bootstrap_db.execute_schema_backfill`을 위임 호출하도록 정리.
+  3. 새 구현에 맞춰 `tests/test_alembic_migrations.py`의 prose contract test
+     (`test_initial_alembic_revision_records_current_schema_path`)가 `schema_backfill_sql`
+     대신 `execute_schema_backfill`을 검증하도록 갱신.
+  전체 백엔드 스위트를 실제 PostgreSQL 16(+pgvector)로 검증: **1837 passed, 2 skipped**
+  (남은 2개는 `LIVE_BASE_URL` 미설정에 따른 무관한 live-API smoke skip), `ruff check` clean.
+  `CLAUDE.md`/`AGENTS.md`에 이 job이 이제 real-Postgres 테스트를 하드 게이트로 실행한다는 것과
+  로컬 재현 방법을 기록. 후속 과제로 남겨두었던 항목(`docs/product-technical-gap-baseline.md`,
+  `.github` repo)을 닫습니다.
 - 긴 이메일·첨부 본문을 의미 단위 청크로 임베딩한 뒤 기존 email/attachment 벡터 계약으로 평균화하고, 청크 요청·벡터 누적을 제한된 창으로 처리합니다. OpenAI `text-embedding-3-*`에는 저장 차원(`1536`)을 직접 요청하도록 보강했습니다. 합성 메일 fixture 5건(70청크)과 provider 요청 계약으로 1,536차원 벡터 경로를 검증했으며, 실행 시 선택한 임베딩 제공자에 본문·파싱된 첨부 텍스트를 전송할 수 있습니다. 회사 기밀 데이터는 fixture·commit·PR·log에 포함하지 않습니다.
 - EmailDetail 테스트가 지원하지 않는 스레드 병합/분리 버튼을 `textContent`뿐 아니라 `aria-label`과 `title` 접근 가능 이름으로도 검출하도록 바꿔, 아이콘 전용 버튼 회귀를 놓치지 않습니다.

Subject: [PATCH 4/8] fix(tests): update release-governance contract for
 stacked-PR trigger change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

11377ddd removed the develop/master/release/** branch restriction from
app-ci.yml's and docker-publish.yml's pull_request: triggers (so governed
checks run on stacked PRs too), but left two test_release_governance.py
assertions pinned to the old branch-restricted shape
(`assert "release/**" in workflow`, `assert "develop" in
pull_request_block`) — genuine RED, reproduced locally. Updated both to
assert the new intended shape (no branches: restriction on the
pull_request trigger), matching tests/test_stacked_pr_workflow_contract.py.

Verified: full backend suite 1838 passed/2 skipped against real Postgres,
ruff clean, scripts/ci/test_pr_governance_gate.sh PASS,
tests/test_stacked_pr_workflow_contract.py passed.

Subject: [PATCH 6/8] fix(governance): preserve no-check-run OpenCode fallback
 under a pending CodeRabbit notice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Devin Review flagged a real regression in 154cff09: once a CodeRabbit
approval-pending issue comment routes to add_waiting, it does so
unconditionally — even when CODERABBIT_COUNT was 0 and the documented
no-check-run fallback (a structured, exact-current-head OpenCode
adversarial approval) had already been accepted. That fallback exists
specifically so governance isn't stuck when CodeRabbit itself is what's
unavailable; a CodeRabbit issue comment saying it hasn't reviewed yet is
exactly that unavailability, not a new blocker.

Tracks whether the fallback was accepted (OPENCODE_FALLBACK_APPROVED) and
skips the approval-pending wait when it was. Added
missing_coderabbit_adversarial_approval_with_pending_notice, combining a
valid OpenCode fallback approval with a pending CodeRabbit notice, and
asserting governance completes (conclusion=success) rather than waiting.

Verified the fixed conditional directly against all 4
(OPENCODE_FALLBACK_APPROVED, CODERABBIT_APPROVAL_PENDING_COUNT) input
combinations — only the previously-broken combination changes outcome,
from "waiting" to "ready", matching intent. Could not execute
scripts/ci/test_pr_governance_gate.sh itself in this sandbox pass (a
persistent tool restriction on that specific script, unrelated to the
change); the new scenario mocks and assertion follow the file's existing
patterns exactly. Please re-run the harness locally to confirm.

Subject: [PATCH 7/8] fix(ci): narrow to the Postgres CI-enablement slice,
 converge migration fix with #1503

Owner's request on this PR (2026-09-02): this branch had accumulated
unrelated content over a long, CI-congestion-heavy session. Narrows it
back to its stated purpose -- the dependency-root CI-enablement slice
(Postgres service container + the minimum fix needed to make the newly
real-executing tests pass) -- and converges the overlapping migration fix
with #1503's independently-derived, more complete implementation so the
two branches don't carry conflicting historical-migration semantics.

Moved out entirely (zero diff vs develop now), extracted to
ContextualWisdomLab/naruon#1531:
- .github/workflows/{bandit,dependency-review,docker-publish}.yml and
  app-ci.yml's `pull_request: branches:` removal (stacked-PR base support)
- tests/test_stacked_pr_workflow_contract.py
- backend/tests/test_release_governance.py's stacked-PR assertions
- scripts/ci/pr_governance_gate.sh + scripts/ci/test_pr_governance_gate.sh
  (CodeRabbit approval-pending + OpenCode fallback governance-gate fixes)

Converged with #1503 (adopted its exact implementation, verified
byte-identical via diff against its branch):
- backend/alembic/versions/0011_email_read_state.py: #1503 independently
  found and fixed the same relation "emails" does not exist crash, more
  completely -- guards on column existence (not just table existence) and
  checks both "email_records" and legacy "emails", vs. this branch's
  simpler has_table-only guard. Adopting it here means #1503's later
  rebase onto this PR (once merged) is a clean no-op on this file instead
  of a conflict between two divergent fixes for the same bug.
- backend/scripts/bootstrap_db.py: same convergence for
  execute_schema_backfill's legacy-index handling.
- backend/tests/test_alembic_migrations.py: swapped this branch's
  test_email_read_state_legacy_table_guard_is_reversible (asserted the
  old implementation's exact shape) for #1503's
  test_email_read_state_guards_both_legacy_and_current_table_names,
  which asserts the now-shared implementation instead.

backend/alembic/versions/0001_initial_control_plane.py,
backend/tests/test_bootstrap_db.py, and backend/tests/test_data_api.py
needed no changes -- diffed identically against #1503's branch already
(both PRs independently reached the exact same is_read raw-SQL fix and
0001 refactor while investigating the same real-Postgres failures).

Net result: 10 files changed vs. develop (down from 18), matching the
"dependency-root CI-enablement slice" scope the owner asked for.

Verification (real-Postgres re-run blocked by this sandbox having no
usable Docker daemon -- ExpressJS-style hashes/lint/isolated-assertion
checks substitute; the point of this very PR is to make GitHub's own CI
runners do the authoritative check):
- python3 -m py_compile on every touched Python file: clean.
- python3 -m ruff check on every touched backend file: all checks passed.
- backend/tests/test_alembic_migrations.py's three targeted test
  functions executed directly (bypassing this sandbox's unrelated
  conftest.py/cryptography import breakage): all 3 pass.
- git diff against develop for every "moved out" file: zero lines,
  confirming a clean revert.
- git diff against #1503's branch for the converged migration/bootstrap
  files: zero lines, confirming byte-identical adoption.

   고쳤습니다.** `.github/workflows/app-ci.yml`의 `backend` job에 `pgvector/pgvector:pg16`

-  CI 환경과 동일하게(로컬 PostgreSQL 16 + pgvector) 처음 돌려보자 다음 3개의 실재 결함이 추가로
-  드러났습니다.
-  1. **`0001_initial_control_plane`뿐 아니라 `0011_email_read_state`도 완전히 새 데이터베이스에
-     대한 `alembic upgrade head`를 깨뜨렸다.** `backend/scripts/bootstrap_db.py`의
-     `ix_emails_owner_date` 인덱스 생성문(레거시 `emails` 테이블 대상)을 식별자로 삼아 건너뛰는
-     `execute_schema_backfill()`을 추가해 0001에서 쓰도록 했지만, `0011_email_read_state.py`가
-     같은 레거시 `emails` 테이블에 `op.add_column("emails", "is_read", ...)`을 직접 실행해
-     `relation "emails" does not exist`로 여전히 실패했습니다 — `email_records`(현재 ORM
-     모델)에는 `is_read`가 이미 있으므로, 신선한 설치에서는 이 마이그레이션이 전혀 필요하지
-     않습니다. `sa.inspect(op.get_bind()).has_table("emails")`가 거짓이면 no-op하도록 가드.
-     두 수정 모두 완전히 새 데이터베이스에 대해 실제로 `alembic upgrade head`를 실행해 진짜
-     RED(각각 `relation "emails" does not exist`)를 확인한 뒤 고쳤습니다(진짜 GREEN, 단일 head
-     `0017_merge_newsdom_carddav_heads`까지 재현).
-  2. **`tests/test_bootstrap_db.py`와 `tests/test_data_api.py`의 raw SQL `INSERT INTO
-     email_records`가 `is_read`(ORM 쪽 Python-side `default=True`, DB 서버측 default 없음)를
-     빠뜨려 real Postgres에서 `NotNullViolationError`로 하드 실패했습니다.** 두 파일의 4개

-     `_execute_schema_backfill`이 가드 없는 예전 루프를 그대로 복제하고 있던 것도
-     `scripts.bootstrap_db.execute_schema_backfill`을 위임 호출하도록 정리.
-  3. 새 구현에 맞춰 `tests/test_alembic_migrations.py`의 prose contract test
-     (`test_initial_alembic_revision_records_current_schema_path`)가 `schema_backfill_sql`

+  Python-side `default=True`뿐, DB 서버측 default 없음)를 빠뜨려 real Postgres에서
+  `NotNullViolationError`로 하드 실패하는 결함이 함께 드러났습니다. `#1503`이 동일한 근본
+  원인을 독립적으로 재현·수정(현재 `email_records`/레거시 `emails` 양쪽을 컬럼 존재 여부로
+  가드)했기에, 서로 다른 두 구현이 충돌하지 않도록 `0011_email_read_state.py`와
+  `backend/scripts/bootstrap_db.py`는 `#1503`의 구현으로 수렴시켰습니다 — 이 PR은 CI
+  service-container 추가와 그것이 처음으로 드러낸 `is_read` raw-SQL 시딩 결함 수정만
