When an ontology view receives denied access while retaining a cached neighborhood, its CSV/JSON-LD buttons remain enabled and selected record or relationship details can remain visible. Apply the existing ADR 0184 denial contract to the shared visible projection so the graph, exact-value table, details and exports all become unavailable together; authorized recovery keeps the existing behavior.

Three synthetic regressions cover initially denied cached data and denial of selected node/edge details. The DeniedCachedEvidence Storybook scene reuses existing tokens and next-action copy. Desktop 1440×900 and mobile 390×844 screenshots were visually audited outside git. The gap baseline separates current exact heads, formal approvals, applicable rules, conflicts, historical candidate runtime evidence and acceptance limits.

Validation:

  • Frontend: 59 files / 566 tests; relevant component/layout suite: 52 tests; lint, production build and Storybook build passed.
  • Existing ontology/cutoff/visibility/SHACL/docstring/document checks: 88 tests; source-window/Voice ingestion: 17 tests. DeprecationWarning was treated as an error.
  • The first full frontend run timed out in the unchanged cited-post popup test; the unchanged App module passed 102 tests in isolation, and the complete rerun with two local workers passed all 566 tests. No timeout or warning suppression was added.
  • Read-only integration checks combine this code with fix(ontology): discard prior evidence when reader scope changes #1157's scope guard and fix(ontology): preserve independently authorized Voice exports #1153's authorized Voice evidence repair after relocating the new test/inventory additions.

Synthetic OIDC preflight returns HTTP 400 and no approved runtime token file is configured. Authenticated PostgreSQL/API/UI and authenticated k6 capacity acceptance remain unavailable for this head. Hosted execution, independent current-head approval and protected merge are still required. Current applicable rules do not enforce those prerequisites, so auto-merge has not been armed because it may merge immediately.

📝 Walkthrough

Walkthrough

OntologyExplorer가 거부 상태에서 캐시된 neighborhood를 숨기도록 변경했습니다. 테스트와 Storybook 스토리를 추가하고, 통합 감사 기록과 Storybook 인벤토리를 갱신했습니다.

status 또는 providedStatus가 denied이거나 status가 authentication_required이면 캐시된 neighborhood를 숨깁니다. 테스트는 거부 응답 후 evidence 비표시와 내보내기 비활성화, ready 상태 복귀 후 표시 복원을 확인합니다. Storybook에 캐시된 Voice가 있는 거부 상태를 추가했습니다.
통합 상태 감사 기록

감사 기록에 denied-evidence 처리와 검증 결과를 추가했습니다. Hosted Checks, 승인 및 규칙 적용, 인증된 API/UI와 k6 검증의 상태도 기록했습니다.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 30409

Cached evidence and exports are covered by denial tests, including rejected continuation pages. No merge-blocking issue is identified; authenticated runtime validation remains incomplete.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 30409

The change strengthens protection by hiding cached evidence when access is denied, without expanding access or privileges. Remaining uncertainty concerns existing cache-recovery behavior and authorization guarantees that have not been validated end to end.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The changed control affects previously loaded or caller-supplied neighborhood evidence in the browser: node/relationship content, exact values, selected provenance, paging and CSV/JSON-LD output. The change does not grant new service privileges or establish backend tenant isolation.

Security Findings and Attack Paths

  • observed — No retained Security findings are supplied. The identified cached-evidence path is narrowed by this PR: after explicit denial, cached content no longer reaches the affected presentation or export sinks. No new caller, greater authority or weaker control was identified in the base/head comparison.

Trust Boundaries and Controls

  • observed — Fetched denial and supplied denial independently block the projection; a non-denied supplied status does not override a concurrent local denial. Supplying neighborhood data remains an existing trusted-caller contract that bypasses fetching in that mode. Server enforcement and the authorization of alternate supplied-data callers were not verified.

Resilience and Maintainability Implications

  • inferred — The control is status-based, not latched until fresh authorization. A new fetch sets status to loading while retained data may remain present; a continuation non-denial error also retains the cache. Reset or retry transitions can therefore project cached data again before a successful response. These loading and cache-retention semantics predate the PR and are not an introduced architecture concern.

Hardening Proposals

  • proposed — If the intended policy requires evidence to remain unavailable after denial until fresh authorization succeeds, define that recovery contract explicitly and validate reset, retry and identity-change transitions against it. A denial latch or cache invalidation would be a separate hardening change, not behavior established by this PR.

연속 페이지의 403/404 거부 경로도 테스트하세요.

첫 페이지를 불러온 뒤 다음 페이지 요청이 403/404를 반환하면 현재 코드는 캐시된 이웃 데이터를 유지하고 로컬 상태를 denied로 바꿉니다. 추가된 테스트는 status="denied" prop만 전달하며, 기존 403/404 테스트는 캐시가 없는 첫 요청만 다룹니다. 따라서 연속 요청에서 로컬 거부 상태가 설정되지 않아 캐시된 데이터가 다시 표시되는 회귀를 잡지 못합니다. 첫 페이지 로드 후 연속 요청을 거부하고 캐시된 데이터가 숨겨지는지 확인하는 테스트를 추가하세요.
