Architecture repair / preservation status — 2026-09-05 KST

Keep this PR Draft. Its threat-source/content delta remains useful, but the current branch must not integrate as an independent outbound-policy authority.

Fresh protected Wardnet truth is main@5829a0f08d78de464dd24393ce5d0f25fba9d126; this branch remains exact aad8224ab664861b540bdf818e9580470cbe89fb from merge base 107117634764c901dff540044585d64088fafedb, and GitHub reports it non-mergeable against current main. Do not mechanically merge or close the stale aggregate head.

Wardnet-owned delta to preserve

A bounded successor from the exact then-current protected main must inventory and carry forward or explicitly prove obsolete the still-valid Wardnet responsibilities here:

  • closed official-source registry for Spamhaus DROP v4/v6, URLhaus and ThreatFox, including source attribution/terms and refresh/freshness metadata;
  • feed-specific response parsing/validation with bounded material cardinality;
  • conditional validator state (ETag/Last-Modified), content SHA-256 and source notice evidence;
  • last-known-good semantics: parse/validate a complete upstream result before atomically replacing only that source's IOC/DNSBL material;
  • source-owned refresh floors, status/error evidence and SOC audit records;
  • feed credential lookup/request payload construction at the consumer boundary without exposing credential values;
  • hostile regressions for oversized/malformed feed bodies, redirects, failed refresh preservation and overlapping source provenance, revalidated against the successor design.

These are gateway/SOC threat-intelligence ingestion and evidence responsibilities, not generic outbound HTTP authorization.

EgressWeave owner boundary

The current branch also directly constructs/sends reqwest requests and thereby carries destination/DNS/redirect/proxy/TLS/resource-policy semantics locally. Under the current CWL bounded-context contract, EgressWeave is the canonical reusable outbound HTTP policy owner. Wardnet must not merge a second semantic implementation merely because the feed sources are Wardnet-owned.

Fresh EgressWeave read shows no immutable GitHub Release. Owner issue ContextualWisdomLab/EgressWeave#237 carries the Rust-consumer requirement; comment 5547499405 adds this PR's fixed-source/conditional-request/LKG use case and acceptance criteria. Until a compatible immutable versioned EgressWeave port/ACL exists, this PR remains a preservation lane. Do not consume mutable EgressWeave source, a PR head, sibling checkout, or cross-service SQL.

The reconstructed Wardnet adapter may own source/purpose identity, feed credentials and request payload, conditional validators, response parsing, LKG state and SOC evidence. EgressWeave must remain authoritative for destination/resolved-address/DNS-rebinding, redirect, ambient proxy, TLS/trust, connection/resource and equivalent reusable outbound authorization semantics. Unsupported/unavailable/unverifiable owner evidence must fail closed.

Other current-owner repairs

This stale branch also predates protected authentication/runtime/governance foundations and modifies broad src/lib.rs/credential/bootstrap surfaces. Rebuild from current protected truth rather than importing those predecessor semantics wholesale. In particular, do not regress the #155 authentication lane, #140 Runtime Configuration boundary, protected #159 workflow-control foundation, or the single-writer docs/product-technical-gap-baseline.md lane.

Reconstruction acceptance

  1. First obtain an immutable compatible EgressWeave Rust-consumer contract/release or verified successor owner boundary.
  2. Start from exact then-current protected Wardnet main and add/retain hostile RED conformance tests for every unique feed-ingestion/LKG invariant being transferred.
  3. Carry only the minimum Wardnet-owned registry/parser/state/audit/consumer adapter delta; replace local reusable egress-policy semantics with the released owner ACL/port.
  4. Revalidate current official source APIs/terms and credential-handling contracts from primary sources.
  5. Reacquire exact-current-head format/tests/Clippy, owned statement/branch/edge coverage, fuzz, security/SAST/CodeQL/Strix, package/SBOM/provenance, review/thread, candidate-base and live governance evidence.
  6. Close this preservation PR only after a protected-main successor demonstrably contains every still-valid unique code/test/fixture/docs/evidence delta or proves a specific item obsolete.

No self/model approval, force push, destructive rebase, routine administrator bypass, predecessor evidence reuse, mutable foreign dependency, gate weakening, or stale aggregate-branch merge is authorized.

📝 Walkthrough

Walkthrough

공식 위협 피드 레지스트리와 Spamhaus, URLhaus, ThreatFox 파서를 추가했습니다. 자격 증명 로딩, 관리자용 조회·갱신 API, 조건부 요청, 해시 기록, 데이터 교체 및 실패 보존을 구현했습니다. DNSBL zone 출력은 호스트 항목만 처리합니다.

Changes

공식 위협 피드

Layer / File(s) Summary
피드 모델과 자격 증명
crates/waf-ids-core/src/lib.rs, src/credentials.rs, src/lib.rs
공식 피드 4개의 메타데이터와 상태를 추가했습니다. ThreatFox·URLhaus 인증 키와 파일·환경 혼합 자격 증명 소스를 지원합니다.
피드 파서와 입력 검증
src/official_feeds.rs, Cargo.toml
Spamhaus JSON, URLhaus CSV, ThreatFox JSON을 위협 지표와 DNSBL 항목으로 변환합니다. CSV 헤더, IPv6 호스트, CIDR, 상태 및 지원 지표를 검증합니다.
피드 조회와 갱신 API
src/lib.rs
인증된 상태 조회와 source별 관리자 갱신 API를 추가했습니다. 조건부 요청, 응답 제한, 전체 응답 검증, SHA-256 해시, 원자적 교체, 304 처리 및 마지막 정상 데이터 보존을 구현했습니다.
DNSBL 출력과 운영 계약
crates/waf-ids-core/src/lib.rs, src/lib.rs, README.md, docs/official-threat-feeds.md
DNSBL upsert 키를 address, prefix_len, source 조합으로 변경했습니다. IPv4 /32와 IPv6 /128만 zone 출력에 포함합니다. 운영 계약과 검증 결과를 문서화했습니다.

종료 신호 초기화

Layer / File(s) Summary
SIGTERM 처리기 즉시 등록
src/main.rs
shutdown_signal이 SIGTERM 처리기를 즉시 등록하고 신호 대기 Future를 반환하도록 변경했습니다.

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

Merge Risk: 🟡 Moderate · up to 29ce2

The PR adds persisted official-feed refreshes that update threat and DNSBL data, but manual imports can collide with official source identifiers and later be overwritten or deleted, while credential-bearing refreshes do not require HTTPS for their initial destination. Merge should wait for these bounded data-integrity and credential-protection risks to be fixed or explicitly accepted.

Refreshed exact head in 1db1b96. The official refresh path now preserves overlapping DNSBL evidence by address/prefix/source without changing manual-import address replacement, parses URLhaus by its documented url header with RFC CSV handling, stores a SHA-256 of each fully validated successful response, and declares refresh/TTL policy per source. Official Spamhaus, URLhaus, and ThreatFox provenance/licensing contracts were rechecked and documented. Local evidence: cargo fmt --check; cargo test --workspace (125 tests, 0 failures); cargo clippy --workspace --all-targets -- -D warnings. The prior Strix failure was provider-unavailable fail-closed evidence (429/410/quota), not a vulnerability finding; hosted checks must rerun on 1db1b96.

Addressed on the current head aad8224: official_feed_authenticated now treats registry-backed admin auth as configured, and tests::official_feed_auth_accepts_registry_only_admin_token covers the regression. Local verification on August 29, 2026 (Asia/Seoul): cargo fmt --check; cargo test.

Fresh repair-first state (2026-09-05 KST): converted to Draft because exact head aad8224ab664861b540bdf818e9580470cbe89fb is non-mergeable against obsolete main@107117634764c901dff540044585d64088fafedb; protected truth is main@5829a0f08d78de464dd24393ce5d0f25fba9d126. The official-source registry/refresh/atomic-last-known-good/terms/credential delta remains valid work, not a close candidate. Reconstruct from fresh protected main with current feed contracts and license/terms evidence revalidated, preserve fail-closed parsing/atomic swap/RBAC/KV credential invariants, then reacquire exact-head hostile/feed-contract/security/coverage/SBOM/provenance/review evidence. No mutable provider assumption, predecessor evidence reuse, force push or aggregate merge.
