Closes #116

Buyer-visible outcome

The embedded admin console no longer needs to reuse a long-lived admin bearer as a browser cookie. POST /admin/session validates once and mints a bounded opaque server-side session; DELETE revokes it. Session cookies are HttpOnly, SameSite=Strict, Secure by default, admin-scope only, and state-changing cookie requests require same-origin Origin/Host evidence.

Review repair

The cookie-authenticated DELETE /admin/session path now uses the same shared origin-validation guard as other admin state-changing routes, so cross-origin logout cannot bypass the documented CSRF boundary.

Current-head verification

  • Exact head: 8000659b7dd299c2564d0d50bbea679cf0bb3810
  • Focused security/admin/CLI/API suite: 32 passed
  • server.py docstring coverage: 100%
  • Ruff, compileall, and diff-check: passed
  • ADR 0022 and doctoring include Figma file vsZMd8WAv42HDRgcZuNcWk and APA 7 references
  • The docstring-only follow-up preserves runtime behavior and was pushed without force

Production keeps Secure cookies. Local HTTP requires the explicit --insecure-admin-session-cookie opt-in. No bearer or business PII is masked into a substitute; access is protected by purpose, expiry, revocation, and audit-compatible boundaries.

Hosted Checks are being regenerated for this exact head. Keep normal protected approval and exact-head Checks; do not bypass.

📝 Walkthrough

Walkthrough

관리자 브라우저 세션을 위한 서버 측 opaque 세션과 쿠키 인증을 추가했습니다. 관리자 UI와 CLI가 새 세션 계약을 사용합니다. 상태 변경 요청에는 Origin 검증을 적용합니다. 세션 만료, 수 제한, 폐기 및 보안 속성을 테스트와 문서에 반영했습니다.

Changes

관리자 세션 인증

Layer / File(s) Summary
서버 측 세션 권한 부여
contextual_orchestrator/server.py
SecurityConfig에 opaque 세션 저장소, TTL, 최대 세션 수, 쿠키 생성·삭제, 자격 증명 검증, 세션 폐기 및 Origin 검증을 추가했습니다.
HTTP 세션 엔드포인트와 상태 변경 보호
contextual_orchestrator/server.py
/admin 셸을 공개 제공하고, POSTDELETE /admin/session을 추가했습니다. 관리자 상태 변경 요청에 Origin 검증을 적용하고 Set-Cookie 응답을 지원합니다.
관리자 콘솔과 CLI 연결
contextual_orchestrator/admin.py, contextual_orchestrator/__main__.py, tests/test_admin_contract.py, tests/test_cli_auth.py
관리자 콘솔이 동일 출처 쿠키를 사용하도록 변경했습니다. 세션 시작·종료 UI와 번역을 추가했습니다. 로컬 HTTP용 --insecure-admin-session-cookie 옵션과 계약 테스트를 추가했습니다.
보안 검증과 운영 계약
tests/test_security_hardening.py, docs/doctoring/admin-session.md, docs/planning/adrs/0022-opaque-admin-browser-sessions.md
opaque 쿠키 속성, 관리자 범위, 추론 API 거부, CSRF 차단, 세션 폐기 및 운영 제약을 테스트와 문서에 반영했습니다.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to d5ebe

Failed admin-session attempts can leave the raw bearer credential visible in the browser form until manually cleared. The risk is localized and straightforward to fix by clearing the field in all outcomes; merge is reasonable with explicit owner follow-up.

Exact current head e602acf8b260a5290a80a74555b2416c4387a798 was independently reproduced before push: final full suite 1437 passed in 609.28s; focused security/admin/CLI/API suite 35 passed; Ruff, compileall, and diff-check passed. The branch implements bounded opaque admin browser sessions, Secure/HttpOnly/SameSite defaults, admin-only cookie scope, same-origin state-change protection, logout/revocation, and an explicit local HTTP opt-in. Auto-squash is armed; protected independent approval and terminal exact-head Checks remain required. No bypass or self-approval.

  • Full exact-tree suite: 1437 passed in 572.88s.
  • Ruff, compileall, and diff checks passed.

@devin review exact current HEAD d670601. The historical Strix failure for this SHA was traced to NVIDIA NIM rate-limit/connection exhaustion before a structured report; the deleted workflow cannot be rerun directly. Do not treat that provider outage as a source finding; revalidate the current diff and request fresh central required workflows for this exact head.

Strix failure RCA for exact HEAD d670601e61ca181a7b7134c7d0219f310334ff05:

  • The first three NVIDIA NIM attempts failed with provider rate-limit/connection errors before a report.
  • The fallback artifact then asserted hardcoded-aws-token at server.py:1932, but the exact PR tree contains no hardcoded-aws-token, AWS_TOKEN, AWS access-key pattern, or secret literal; line 1932 is the multimodal validator, and the reported replacement is an LLM-generated hypothetical diff.
  • Semgrep, CodeQL, Trivy, dependency review, supply-chain, full unit, property, and coverage checks pass.

This is a Strix/provider false positive plus backend exhaustion, not a source credential finding. Re-running the failed Strix job now; no gate weakening or bypass.

Exact-head security/admin/CLI suite 32 passed in 8.75s; git diff --check origin/main...HEAD passed; no hardcoded AWS-token pattern exists in the exact tree. Full-tree Ruff reports three pre-existing test-baseline findings in unchanged files (test_chat_tools_shape_http_honesty.py, test_functions_null_max_tool_calls_null_http_honesty.py, test_responses_tools_shape_http_honesty.py); git diff --quiet origin/main...HEAD confirms #788 does not introduce them. The shared baseline cleanup is already carried by #789; no unrelated duplicate patch was added to this security PR. Hosted required Checks and independent approval remain the gates.

🔍 Readiness panels no longer refresh after simulate or evaluation

simulate() (contextual_orchestrator/admin.py:1588) and runEvaluation() (contextual_orchestrator/admin.py:1627) drop the previous refreshReadiness() call. Readiness reports include evaluation-usage metrics, so those panels now stay stale until a full reload. This may be an intentional cut of ~24 authenticated requests per action, or an accidental regression.

🔍 evaluation_runs POST now requires admin scope

The scope selector now routes /api/v1/evaluation_runs to admin scope, whereas it was previously inference. This is needed so the admin session cookie can drive runEvaluation, but it is a contract change: existing clients using an inference bearer to start evaluation runs will now receive 401.

…earer (#844)

* fix: session-cookie requests partition the response cache without a bearer

Merging #772 (distributed cache) with #788 (opaque admin sessions) left a
gap: _cache_partition required a bearer header, so every state-changing
admin POST from a cookie-authenticated operator failed with 401 before any
handler logic ran. An active opaque session id now derives the partition
(random per login, so cross-session reuse stays impossible), and a
regression test locks the flow in.
