현재 exact head는 의도한 readiness semantic RED가 아니라 repository/DDD prerequisite에서 실패합니다. 수리 후 재검증이 필요합니다.
- PR이 protected
develop에서 독립 crate/CI를 새로 만들었습니다. 현재 canonical root #15c6a44bb2b35eb17d0315d72db242f4488c3c426의 Rust 1.97/Edition 2024, pinned/exact-head CI, coverage/security gates와application_service/sandbox_execution경계를 우회합니다. 이 delta는 root를 ordinary non-force ancestry로 채택하고, 별도 Cargo/CI foundation을 제거해야 합니다. - exact CI
34254527569은cargo test --all-targets에서 끝났고, branch에는 Cargo가 선언한src/main.rs가 없습니다. 테스트에도 raw byte-string/JSON 기대값 문법 오류가 있어 현재 failure는 readiness semantic RED가 아닙니다. provider_terminated와model_communication_failed는 이 runtime의 readiness domain truth가 아닙니다. AGENTS/CLAUDE/Context Map상 provider/model failure classification은 contextual-orchestrator 등 consumer/LLM owner에 남겨야 합니다. Runtime은 sandbox readiness/cleanup 및 backend-neutral failure evidence만 소유해야 합니다.origin: String을 caller가 직접 주는 형태는 runtime-owned loopback endpoint를 우회하는 불필요한 authority입니다. readiness는 runtime이 생성·검증한 loopback service identity에 bind해야 하며 arbitrary origin을 새 public capability로 만들면 안 됩니다.- Caido
loginAsGuest자체를 Core UL로 올리지 마십시오. 현재 TRD는 HTTP P0가 TCP reachability만 검사한다고 명시하므로, 필요한 repair는application_service안의 bounded/versioned typed HTTP readiness contract와 ADR/PRD/TRD 업데이트입니다. backend adapter는 Podman/Docker/Colima에 독립적으로 남겨야 합니다.
다음 head는 기존 #104의 유효 test intent를 보존하되 canonical root 위에서 compile/execution 가능한 RED로 다시 세우고, exact CI가 실제 TCP-open but HTTP-handshake-not-ready acceptance gap까지 도달한 뒤에만 최소 production GREEN을 넣겠습니다.
Adopt root #1 by ordinary two-parent ancestry, discard the invalid duplicate crate/workflow scaffold, and preserve the real readiness intent as an application-service semantic RED plus traceability. No production behavior changes.
Preserve TCP reachability semantics, but require a bounded loopback HTTP response before issuing an HTTP lease. Add positive and server-error protocol cases while retaining timeout cleanup. No caller origin or consumer/provider taxonomy is introduced.

Inline comments:
In `@docs/product-technical-gap-baseline.md`:
- Line 14: Update the integration statement in the baseline document to clearly
distinguish policy from current release status: use normative wording such as
“must use” for the consumer integration requirement, and explicitly identify the
released contract or artifact only if it is currently available. Keep the
existing restrictions on source imports, mutable PR-head dependencies, direct
foreign runtime calls, and cross-service SQL.
- Line 3: Update the “Last reviewed on” date in the document to the actual
completed review date, ensuring it is not a future date relative to the current
KST date; leave the referenced commit and PR evidence unchanged.
In `@src/infrastructure/podman.rs`:
- Line 890: Update the readiness status validation in the response-checking flow
to parse the complete three-digit HTTP status code and accept only values from
200 through 299, rejecting malformed variants such as invalid second or third
status characters. Add regression coverage for invalid characters in both
positions while preserving acceptance of valid 2xx responses.
- Around line 24-25: Update the HTTP readiness request generation in the podman
readiness probe to include the runtime host_port in the Host header as
127.0.0.1:{host_port}, creating the request per probe instead of using the fixed
HTTP_READINESS_REQUEST constant. Add a responder regression test that verifies
the requested Host value matches the selected port.

Single-writer repair finding: this focused issue #103 HTTP-readiness child still changes repository-wide docs/product-technical-gap-baseline.md, while live Gap authority is maintained by #121. The delta contains valid readiness causal/review evidence and the normative immutable-release consumer rule, so do not simply drop it. Migrate the owner-specific evidence to local doctoring first, retain the PRD/TRD/ADR contract updates, then restore only the global Gap file byte-for-byte to exact-base 5c6a44bb2b35eb17d0315d72db242f4488c3c426 blob bacb346f2ce4259a4f55bd3bece5e871b06d69db by ordinary fast-forward. This docs-only movement invalidates predecessor exact-head GREEN as current merge evidence; no force rebase, production/test change, or status transfer.
