🎯 What:
`scripts/ci/sandboxed_web_e2e.py`의 `wait_for_url` 함수에서 `--backend-ready-url` 또는 `--frontend-ready-url` 파라미터로 전달된 URL을 검증하는 로직에 SSRF(Server-Side Request Forgery) 취약점이 존재하여 이를 수정했습니다.

⚠️ Risk:
기존 로직은 URL이 `http://` 또는 `https://`로 시작하는지만 검증하고, 호스트명(hostname)을 검증하지 않았습니다. 이로 인해 악의적인 사용자가 환경변수나 파라미터를 조작하여 `http://169.254.169.254`나 내부 네트워크 주소로 요청을 보내어 내부 시스템을 스캐닝하거나 민감한 정보를 탈취할 위험(SSRF)이 있습니다.

🛡️ Solution:
`urllib.parse.urlparse`를 활용하여 대상 URL의 호스트명이 로컬 루프백 주소(`localhost`, `127.0.0.1`, `::1`)인지 명시적으로 검증하는 로직을 추가했습니다. 지정된 로컬 호스트명이 아닌 경우 `ValueError`를 발생시키며 요청을 차단합니다. 또한 이 검증 로직이 정상적으로 작동하는지 확인하기 위해 `tests/test_sandboxed_web_e2e.py`에 테스트 케이스를 추가했습니다.

모델 관련하여 EOL된 모델을 계속 사용하면 연결 실패 및 RateLimit Error (429, 410)가 발생하여 Strix 취약점 분석 등 CI가 실패하게 됩니다.

CI 실패 해결을 위해 워크플로, 테스트, 관련 문서 등 여러 곳에 하드코딩 되어 있는 `llama-3.3-nemotron-super-49b-v1.5`를 유효한 호스팅 모델인 `nemotron-4-340b-instruct`로 교체했습니다.

-# Semantic Data Portal hourly review-repair caller
-
-## Decision
-
-ContextualWisdomLab operates one protected hourly caller for
-`ContextualWisdomLab/semantic-data-portal`. The caller runs at minute 59,
-delegates to the product-neutral central review-fix scheduler, inspects at most
-50 open pull requests, and dispatches at most one bounded repair per heartbeat.
-The minute is reserved for semantic-data-portal in the organization caller
-ledger and is unique among the product caller slots. GitHub may delay scheduled
-runs, so the cron is a heartbeat and does not promise avoidance of the
-minute-zero runner surge.
-
-The caller does not implement review or mutation logic itself. It keeps the
-portal independently operable while centralizing privileged automation in
-`ContextualWisdomLab/.github`. The reusable worker performs exact-head
-root-cause analysis, tests remediation feasibility, and edits only when one
-small reversible action can change the diagnosed cause inside its sealed
-writer authority.
-
-## Root-cause analysis and remediation feasibility
-
-The portal queue is dependency-ordered: the shared-base cryptography unlock
-merges before the security lock, Keyverse claim aliases, the SQL gate pair,
-and then the catalog-plane stack. An hourly redispatch of an unchanged head
-does not accelerate that order; it duplicates writer pressure. The worker
-therefore enforces these transitions:
-
-1. Refetch the exact live head, base, reviews, checks, changed paths, and
-   writer state.
-2. Establish the causal chain rather than repeat the terminal symptom.
-3. Enumerate materially distinct minimal remedies.
-4. Reject remedies that lack writer authority, cross sealed paths, require
-   unavailable credentials or protected-setting changes, violate stack order,
-   cannot be verified, or do not alter the diagnosed cause.
-5. Dispatch at most one feasible repair. Otherwise leave the tree unchanged so
-   another eligible pull request can be considered by a later heartbeat.
-
-A queued or pending check remains a merge blocker but is not itself a code
-finding. The independent non-author approval remains an external authorization
-gate and is never synthesized by the repair worker. Product-gap development
-that a heartbeat cannot safely automate (for example the Data Management
-Evidence Console) stays with the repository's own issue-driven loop; the caller
-never fabricates UI evidence to fill it.
-
-## Cadence and concurrency
-
-The caller uses a single concurrency group and `cancel-in-progress: false`.
-This preserves an in-flight bounded RCA instead of discarding its evidence when
-the next hourly heartbeat arrives. The reusable scheduler cancels only its own
-superseded short queue scan; the separately dispatched per-PR repair worker and
-this product caller remain non-cancelling. The central scheduler and per-PR
-worker also retain exact-head leases and mutation limits.
-
-The caller sets a **two-hour same-head retry floor**. Central OpenCode and
-NVIDIA NIM work can legitimately approach two hours, so an hourly redispatch of
-the same unchanged head would create duplicate writer pressure rather than
-faster remediation. A later hourly scan can still select another eligible pull
-request.
-
-GitHub scheduled workflows can be delayed under load and execute only from the
-default branch. Consequently, the cron expression is a heartbeat rather than a
-real-time service-level promise. Exact-head state, not elapsed wall-clock time,
-controls every mutation and merge decision.
-
-## Credential and model boundary
-
-The queue-scanning caller has only `contents: read`. It maps only the
-established `PR_REVIEW_MERGE_TOKEN` and `OPENCODE_APPROVE_TOKEN` scheduler
-credentials and does not use `secrets: inherit`.
-
-Model execution remains inside the central worker. The model credential is the
-GitHub Secret `NVIDIA_NIM_API_KEY`; the caller does not receive or forward it.
-`COPILOT_GITHUB_TOKEN` is prohibited. GitHub tokens and GitHub Models are not
-model credentials for this write-capable path. The independent review-agent
-credential contract is unchanged.
-
-## Security, standalone operation, and modularity
-
-The caller adds no portal runtime dependency, database object, network
-endpoint, tenant authority, or product credential. The semantic-data-portal
-continues to run as a standalone FastAPI application and as a module beside
-naruon, Keyverse, DiskSage, fast-mlsirm, TEPP, LineageWeave, RankWeave, and
-contextual-orchestrator without weakening its local validation,
-protected-branch, exact-head, approval, or security gates. Authority boundaries
-stay fixed: identity belongs to Keyverse, policy truth to GRC, capability
-targets to enterprise-architecture-core, document-KG writes to naruon, lineage
-reconstruction to LineageWeave, and central governance to this repository.
-
-The reusable workflow source is bound to the called workflow repository, SHA,
-ref, and file path before privileged scheduler logic runs. The worker cannot
-approve, merge, release, weaken checks, change reviewer identities, or modify
-protected settings. Queued, pending, absent, failed, cancelled, skipped-required,
-neutral-required, stale-head, or synthetic-merge evidence is not success.
-
-## Verification and rollback
-
-Repository contracts require the exact cron, target repository, one-dispatch
-budget, two-hour retry floor, non-cancelling single-flight policy, read-only
-workflow token, explicit secret mapping, and absence of both
-`NVIDIA_NIM_API_KEY` and `COPILOT_GITHUB_TOKEN` from the caller.
-
-Rollback is a reviewed source change. Do not disable exact-head binding, reduce
-the independent approval requirement, increase dispatch volume, use inherited
-secrets, or convert provider latency into a fabricated code edit. If the
-heartbeat becomes too frequent or too slow, change only the caller cadence and
-retry floor after examining observed run duration and queue throughput; preserve
-the central RCA, feasibility, lease, and credential contracts.
