Exact-current-head review request for Review the complete five-file credential-egress repair: raw and parsed HTTPS-only endpoint; fail-closed DNS error/empty/malformed results; rejection of every non-global or multicast address including shared address space; no redirects; bounded 1 MiB response; no endpoint or credential reflection; and operator guidance retaining trusted DNS and egress policy as residual controls. Both CodeRabbit findings are addressed and resolved. Trusted uv Materializer Quality CI, Strix Changed Path Quality CI, CodeQL PR, Python Security, Security Scan, SAST Semgrep, Secret Scan, OSV-Scanner PR, Scorecard PR, and SBOM Generation are terminal-success on this exact head. Keep the head unchanged. Do not update the branch, synthesize author approval, relax DNS/TLS validation, add silent fallback, merge, release, or bypass protection. @coderabbitai review |

Exact-current-head automated and independent review requested for Fresh evidence: all directly observed exact-head workflows are terminal-success and both source-backed CodeRabbit findings are resolved. Review the credential-egress boundary: raw and parsed endpoints must be HTTPS; DNS error, empty results, malformed addresses, every non-global address (including 100.64.0.0/10), and multicast must fail before request construction; redirects remain disabled; response body is capped at 1 MiB before JSON decoding. This is DNS preflight plus organization egress policy, not a claim of complete rebinding elimination. Submit an exact-head verdict without updating the branch, weakening global-address/TLS checks, logging endpoint credentials, synthesizing author approval, or bypassing protection. @coderabbitai review |

Exact-current-head review request for Review the unchanged current tree read-only, verify all security and evidence boundaries, and report only current-head findings. Do not update the branch or bypass the required independent approvals. @opencode-agent review |

@opencode-agent review Review exact current head only. Do not merge, mutate credentials, or synthesize author approval. GitHub review/Checks wait is not a blocker for the remaining queue. |

Reviewed. Review threads already resolved. Added APA 7th doctoring (RFC 1918, 6598, 9110) and ARCHITECTURE.md. Shared/multicast DNS tests remain fail-closed before Authorization. Local suite 979 passed x2. Auto-merge armed. |

Returned to Draft because the exact current tree mixes the Noema credential-egress repair with unrelated trusted-uv materializer and governance branches. The security slice is valid and should remain bounded: HTTPS-only endpoints, fail-closed DNS resolution, globally routable unicast-only addresses, no redirects, and a 1 MiB response limit before JSON decode. Head Rebuild from protected |

Current-head validation for 724c994: corrected the shared Strix gate to block only CRITICAL/HIGH/MEDIUM severity, while Low/INFO and provider infrastructure output without medium-or-higher evidence remain neutral and available as artifacts. Added the focused regression contract. Passed: 28 Noema/scheduler tests, actionlint for Strix, bash -n for the Strix harness, and git diff --check. Please review this exact head; merge remains gated on an independent non-author approval and terminal protected checks. |
|
@opencode-agent Please review the current PR head 724c994 on the exact branch. Re-check the Strix threshold/scope gate, Noema DNS fail-closed changes, current mergeability, and required checks. Do not approve a stale head. |

Current-head failure triage for central run 32405892362: the failing Hourly cadence, immutable source, NIM credential, and conflict scope / exact-head-path-policy wrapper is executing the shared Strix fallback contract tests, not the PR's product files. The concrete failures are stale assertions in tests/test_strix_nvidia_nim_not_found_fallback.py that do not accept the current vulnerability-count signal. The root-cause repair is central PR #1177 at exact head a6ab307, which narrows the retry classifier and updates those assertions. No unrelated source patch is warranted on this PR; regenerate this PR's exact-head checks after #1177 is normally merged. |

Current-head repair is pushed at . The shared Strix vulnerability contract now keeps Critical/High/Medium evidence fail-closed and treats only non-assessable/info-only provider output as neutral. Focused regression tests and shell syntax checks passed. @opencode-agent review this exact HEAD; do not transfer predecessor approval or merge. |

The PR had no merge-base with main. Re-apply only the Noema endpoint gate, tests, and doctoring so localhost/metadata/non-global DNS stays fail-closed without deleting later hourly-repair sources.

Superseded by clean current-main replacement #1279 at exact head b19c5b4. The replacement preserves the trusted #1120 loopback sidecar seam, excludes the unrelated Strix and lockfile scope, adds pre/post DNS identity and bounded-response regressions, and records the residual deployment boundary. All seven current threads were answered and resolved before closure. |

Purpose
Fail closed before a credentialed Noema model request when its configured endpoint uses plaintext transport or DNS preflight cannot prove a non-empty set of valid globally routable unicast addresses.
Exact identity and bounded scope
main@55a8b576725451dfe0a21a57d36a2f1a41619b24(verified 2026-08-21);a9c5aa134a6c2507acb1abd2e0022fe0cee30607;3d7ae8c37079a6692721dfd49b535f1fbf4216bd;Later branch updates mixed in unrelated central AGENTS/Architecture/CLAUDE and trusted-lock installer-test changes. A non-destructive forward cleanup restores those paths to protected-main content while retaining the Noema-specific operator doctoring. No force-push, rebase, history rewrite, predecessor evidence transfer, or gate weakening was used.
Every check, review, approval, or generated merge result bound to an earlier head is historical only. Current-head evidence must regenerate.
RCA
The SSRF preflight caught some private/local resolved addresses but ignored
socket.gaierrorand skipped malformed resolver entries. The HTTP opener then performed its own later resolution while carrying the model API key. A transient or malicious malformed result therefore crossed the advisory guard, and anhttp://endpoint could receive the credential without TLS.The immediate cause was permissive exception/entry handling. The root cause was treating endpoint validation as best-effort advice rather than part of the credential-egress boundary.
Remedy and rejected alternatives
The bounded repair:
Silent retry/fallback was rejected because integrity/TLS failures are not transient evidence. Logging endpoint or credential material was rejected. A fixed provider-host allowlist was rejected because the product intentionally supports administrator-owned compatible endpoints.
Test-first evidence
The branch records RED cases for unresolved DNS, plaintext transport, and shared address space reaching the opener, followed by GREEN focused endpoint/security tests, Noema coverage tests, complete central tests, 100% Noema statement/branch coverage, public docstrings, compilation, and diff checks on the predecessor bounded tree.
Those results are lineage only. The current head must regenerate every applicable exact-head quality, security, supply-chain, and semantic-review result. Pending, queued, skipped, cancelled, absent, stale, predecessor-head, local-only, author-only, status-only, synthetic, or model-only evidence is not acceptance.
Merge and operational acceptance
Merge or auto-merge only after the unchanged current head has terminal-success required gates, zero valid unresolved findings, a qualifying current-head semantic verdict, two qualifying independent non-author approvals including last-push approval, compatible live-base evidence, and ordinary expected-head branch-protection authorization. After protected integration, exercise a real configured HTTPS Noema endpoint and prove DNS/TLS failures cannot emit a review while a valid public endpoint can. No self-approval, administrative bypass, synthetic approval, or protection weakening is requested.
