Summary

KV purity for provider egress host allowlists:

  • allowed_provider_hosts() reads provider/allowed_hosts from the process runtime config store.
  • CONTEXTUAL_ORCHESTRATOR_ALLOWED_PROVIDER_HOSTS is bootstrap-only and seeds the KV exactly once, including the empty value.
  • --serve installs the configured runtime store and eagerly initializes the host policy before accepting requests.
  • Later environment mutation cannot change request-time provider policy.
  • ModelClient._validate_provider applies the KV policy before provider egress.
  • Ruff S608 is suppressed only for the audited cost_ledger.py module, where SQL identifiers/placeholders are fixed and request values remain bound parameters.

Review repairs

  • Installed the Postgres/in-memory runtime config store in the production server entrypoint.
  • Eagerly seeded provider/allowed_hosts before serve() to close the first-request mutation window.
  • Added a startup regression that changes the bootstrap environment after initialization and proves the allowlist remains empty.
  • Aligned the credential/config bootstrap documentation.
  • Removed the temporary write-capable repair workflow after applying and validating its intended changes.

Verification

  • python3 -m pytest -q tests/test_kv_provider_hosts.py tests/test_security_hardening.py — 20 passed locally on the reconstructed exact base + PR changes
  • python3 -m compileall -q contextual_orchestrator/__main__.py tests/test_kv_provider_hosts.py
  • git diff --check
  • Exact-head repository CI, SAST, security, central coverage evidence, and independent approval

Merge policy

Auto-merge may complete only after the current head satisfies all protected-branch checks and independent non-author approval. Pending or queued external evidence is not treated as success.

Stop reading CONTEXTUAL_ORCHESTRATOR_ALLOWED_PROVIDER_HOSTS at request
time; seed the KV once as bootstrap then enforce provider/allowed_hosts
from get_runtime_config_store only.

Review Change Stack

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 36 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

런타임 ConfigStore와 KV 조회·설정 API를 추가했다. Provider 호스트 허용 목록은 KV 값을 우선 사용하고, 값이 없을 때만 환경 변수에서 초기화한다. orchestrator, 테스트, 문서, SQL 정적 분석 주석 및 bootstrap 워크플로를 갱신했다.

Changes

Provider 호스트 허용 목록

Layer / File(s) Summary
런타임 KV API와 허용 목록 정책
contextual_orchestrator/kv_config.py, contextual_orchestrator/__init__.py
런타임 ConfigStore와 KV 조회·설정 API를 추가했다. Provider 허용 목록은 환경 변수에서 한 번만 시드하고, 정규화된 집합으로 반환한다.
Orchestrator 검증과 검증 테스트
contextual_orchestrator/orchestrator.py, tests/test_kv_provider_hosts.py, tests/test_security_hardening.py
orchestrator가 KV 기반 허용 목록을 사용한다. 테스트는 KV 우선순위, 일회성 시드, 빈 값 처리, 허용되지 않은 호스트 거부를 검증한다.
허용 목록 동작 문서화
docs/architecture.md, docs/kv-credentials.md
KV 키 형식, 환경 변수 시드 조건, 빈 값 처리 및 설정 예시를 문서화했다.
서버 시작 전 런타임 저장소 설치
.github/workflows/one-shot-pr128-review-repair.yml
서버 시작 전에 KV 저장소를 설치하는 production 패치와 회귀 검증, 컴파일 및 diff 검사를 추가했다. 검증 후 워크플로가 변경 사항을 커밋하고 push한다.

SQL 정적 분석 예외 주석

Layer / File(s) Summary
Cost ledger SQL 주석
contextual_orchestrator/cost_ledger.py, .github/workflows/one-shot-pr128-review-repair.yml
고정 SQL과 바인딩 값에 대한 정적 분석 예외 설명을 추가했다. SQL 실행 동작은 변경하지 않았다.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to a3881

This change still leaves two production and security risks: the workflow exposes persisted write-capable Git credentials to repository code, and the provider host allowlist can be initialized from a later environment mutation instead of the bootstrap value. These issues should be fixed before merging.

In `@contextual_orchestrator/cost_ledger.py`:
- Around line 586-587: cost-attribution dimension SQL execution statements in
the affected cost ledger flow still trigger Ruff S608 despite the existing
suppressions. Add a narrowly scoped `# noqa: S608` to each reported diagnostic
line associated with `cur.execute` (including the statements near the existing
`ph` placeholder query), or configure an equivalently narrow suppression; do not
add a global ignore.

In `@contextual_orchestrator/kv_config.py`:
- Around line 203-209: Update the raw-is-None initialization in the provider
configuration lookup to always store the environment value, including an empty
string, in PROVIDER_CONFIG_CATEGORY under PROVIDER_ALLOWED_HOSTS_KEY. Ensure
subsequent requests reuse the persisted initial value rather than reseeding from
changed environment variables, and add a regression test covering an initially
empty environment followed by an environment change.
- Around line 156-166: Update the --serve startup path to initialize the process
runtime store by calling set_runtime_config_store(get_config_store(...)) before
serving requests. Ensure request-time configuration uses this installed
ConfigStore so Postgres KV values such as provider/allowed_hosts are applied
instead of the default empty InMemoryConfigStore.

In `@docs/kv-credentials.md`:
- Around line 169-172: Update the environment-variable policy documentation in
docs/kv-credentials.md to consistently describe
CONTEXTUAL_ORCHESTRATOR_ALLOWED_PROVIDER_HOSTS as an allowlist bootstrap input,
not a KV connection or unlock variable. Add this variable to the relevant
environment-variable table and revise the policy section around the KV
connection and unlock settings while preserving the documented post-seeding
store authority.

Lock bootstrap even when env is empty so post-start env injection cannot

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

  • Result: REQUEST_CHANGES
