fix(strix): make Azure and cross-provider fallbacks executable

[seonghobae]

Current exact-head recovery (2026-08-24)

• Head: ab3d764547082e1b55b6257cc1cd9aa5d951fa30
• Protected base: main@613a33e0cb1c6db9790fae99f6253445712ac37a
• Adopted protected-main PR fix(strix): unblock trusted smoke during provider-prefix migration #1286 as the second parent without force-push. Its temporary either-prefix smoke compatibility was resolved in favor of this owner branch's completed openai_direct/* migration and explicit rejection of retired openai-direct/*.
• Recreated GitHub tree ed281e2f4a50bad277524b7282ab490d1661e466 byte-for-byte from the locally verified merge, then advanced the branch by compare-and-set fast-forward.
• Local GREEN: required-workflow smoke PASS, full test_strix_quick_gate.sh PASS, and git diff --check PASS.
• Hosted exact-head GREEN: Strix Changed Path Quality run 32712853098, job 97387791739, checked out exact SHA ab3d764547082e1b55b6257cc1cd9aa5d951fa30, passed 1,417 tests with 1 skip and 16 subtests, and recorded test_strix_quick_gate: PASS.
• Organization Commercial Readiness, Exact Artifact SBOM Attestation, and OpenCode Rust Coverage Toolchain quality workflows also completed successfully on the exact head.
• CodeQL and eight security/SBOM workflows remain pending or queued and are non-passing until terminal.
• Unresolved review threads: 0 at publication.
• Exact-current-head qualifying formal verdict: absent.

Decision: WAIT_FOR_TERMINAL_EXACT_HEAD_CHECKS_AND_INDEPENDENT_FORMAL_REVIEW.

Previous exact-head recovery (historical)

• Head: 7011fee275eaa257ce491efb4812dd3e98ed649e
• Protected base: main@0c6b9a6459c9dbdf5e23fb01df7a32a8a14964b3
• Causal repair chain: the owner tree restores exact provider credential/endpoint isolation, authenticated failure classification, severity-boundary parsing, typed non-passing incomplete scans, and trusted-lock installation. It removes the duplicate direct-OpenAI fallback that normalized to primary gpt-5.6-luna; bounded same-model retries remain, and exhausted direct-primary execution fails closed. The current test makes the final empty-default fallback behavior explicit.
• Local owner-tree GREEN: 1,407 passed, 1 skipped, 16 subtests; full test_strix_quick_gate.sh: PASS.
• Hosted exact-head GREEN: Strix Changed Path Quality run 32693699962, job 97331828910, checked out exact SHA 7011fee, ran 1,407 tests·16 subtests, and recorded test_strix_quick_gate: PASS.
• Unresolved review threads: 0.
• Security/SBOM workflows remain queued and therefore non-passing; exact-current-head formal Reviews API verdict is absent.

Decision: WAIT_FOR_TERMINAL_EXACT_HEAD_CHECKS_AND_INDEPENDENT_FORMAL_REVIEW.

Supersedes #1213 with the protected-main replacement for the unsupported-temperature and cross-provider Strix failure. It also absorbs the two unique quality-path triggers from closed duplicate #1262.

Root causes

• Azure rejected the implicit temperature=0.2 sent for gpt-5.6-sol, while LiteLLM had no fallback model group for that selector.
• The outer fallback passed the workflow-facing openai-direct/ alias through without a valid LiteLLM provider, inherited the NVIDIA endpoint and credential, and failed before authoritative vulnerability evidence existed.
• A privileged same-repository Strix PR could replace the trusted workflow dependency lock with its PR-head lock before provider credentials reached the installed scanner.

Repair

• Recognize only the known full-line unsupported-temperature capability failure and reject split-line, target-prefixed, numeric-continuation, and standalone-brownout imitations.
• Require a non-identifier leading boundary on every severity marker so configuration identifiers such as STRIX_FAIL_ON_MIN_SEVERITY cannot be promoted into vulnerability findings; identifier-only reports remain non-authoritative and fail closed.
• Normalize openai-direct/ to trusted selector openai_direct/, then dispatch through LiteLLM provider form openai/ with the established direct-OpenAI credential and no inherited NVIDIA API base.
• Skip candidates lacking their trusted key, continue bounded fallback, and remain fail closed when exhausted.
• Keep only exact console/report advisories on the bounded allowlist; altered warning text remains blocking.
• Install only from the trusted workflow checkout lock, reject missing/symlinked locks, compare exact on-disk bytes with HEAD:requirements-strix-ci-hashes.txt via git hash-object --no-filters, and require hash-pinned wheels.
• Pin the smallest compatible LiteLLM wheel (1.94.2) because 1.94.1 has no Python 3.13 manylinux wheel.
• Retain the current default-branch smoke marker solely for bootstrap compatibility while executable contracts forbid a PR-head lock source.

Predecessor exact-head verification (non-passing after head movement)

• Head: 0445447310257bbd5eef1975c5dbcdf649f311df
• Protected base: main@93b9cbb145bfe03453c9421dcf7e0668da0f8050
• RED (provider alias): all four active fallback branches used openai-direct/gpt-5.6-luna; the focused contract failed because LiteLLM routing requires canonical openai_direct/*.
• RED (history integrity): required OpenCode run 32683332756, coverage job 97303853223, correctly rejected predecessor 05feeb1… because its post-merge restoration looked like a stale replay after the damaged 844cef4… merge tree.
• Causal history repair: merge anchor f428b3e553b8e52c4b0eacc46bc2941bef0aa231 keeps the complete owner tree and rebinds protected main as the second parent without changing content; the current doc-only descendant does not revert merged base work.
• Focused GREEN: 16 deterministic NVIDIA/provider fallback regressions, required-workflow smoke, shell syntax, and git diff --check pass; every active fallback branch uses openai_direct/gpt-5.6-luna, while only a scoped frozen-smoke compatibility comment retains the historical alias.
• Full Python: 1,407 passed, 1 skipped, 16 subtests.
• Full Strix quick-gate harness: PASS.
• Hosted exact-head run 32684026983, job 97305671238: exact checkout SHA attested, 1,407 tests·16 subtests and full quick-gate PASS.
• All 13 substantive exact-head repository workflows completed successfully; the repair-only workflow was skipped and is not counted as passing evidence.
• Duplicate fix(strix): correct STRIX_FALLBACK_MODELS provider prefix (hyphen -> underscore) #1285 was revalidated through its raced final head and closed after its provider-prefix and credential/endpoint-isolation intent was proven already present under this canonical owner.
• Unresolved review threads: 0.
• Exact-current-head formal Reviews API verdict: absent; predecessor CHANGES_REQUESTED, COMMENTED, and status-only evidence are non-passing.

No secret, raw-provider, approval, protection, model-selection, severity threshold, or incomplete-scan success boundary is weakened.

Decision: WAIT_FOR_INDEPENDENT_EXACT_HEAD_FORMAL_REVIEW.

Estimated code review effort: 4 (Complex) | ~75 minutes

Merge Risk: 🟡 Moderate · up to 026c2

The PR makes Azure and cross-provider fallback routing executable and constrains dependency installation to the trusted lock, reducing fallback failures and untrusted dependency risk. Functional checks pass, but current-head security/SBOM validation is still queued and one documentation reference is invalid, so merge should wait for terminal validation and the small documentation fix.

@opencode-agent review

Independent exact-current-head review requested for 1fd718f3177d3e8ffe908aed38b50dc94e926f8d (base main@885f2cd251999f21cf562cab3e2d9cc3cc3ec737).

Verification on this exact head:

• RED reproduced repository-controlled TARGET OUTPUT: Error: litellm.BadRequestError ... incorrectly authorizing a cross-provider fallback; the anchored provider-line matcher and target-prefix fixture are now GREEN.
• Focused provider/fallback suite: 16 passed.
• Full local suite: 1,395 passed, 1 skipped, 16 subtests.
• Hosted Strix quality run 32648578834/job 97216588527 checked out this exact SHA, passed the same 1,395-test breadth, and completed test_strix_quick_gate: PASS.
• Hosted organization policy run 32648578846/job 97216556061 checked out this exact SHA and passed 34 tests.
• Current review threads are resolved. Pending/queued checks and predecessor reviews are not counted; please issue a formal Reviews API verdict only for this exact head.

[seonghobae]

Exact-head 1fd718f3177d3e8ffe908aed38b50dc94e926f8d remains blocked on two independent human approvals under ruleset 18156473. Bot reviews (Devin/CodeRabbit) are present but do not satisfy the ruleset. Requesting independent review so the required-workflow SHA can pick up the openai-direct rewrite. Do not weaken scanner gates.

[seonghobae]

Strix default-branch dispatch exposed a real privileged-workflow supply-chain defect: the scan replaced the trusted workflow dependency lock with a same-repository PR-head lock before provider credentials later reached the installed scanner. Exact head de3abcd removes that materialization and makes both bounded smoke contracts plus pytest enforce trusted-source-only dependencies. Validation: 1396 passed, 1 skipped, 16 subtests; focused Strix set 40 passed plus 16 subtests; required-workflow smoke and shell syntax passed; git diff --check passed. No gate was weakened: incomplete provider scans and reported vulnerabilities remain non-passing.

[seonghobae]

Strix default-branch dispatch exposed a real privileged-workflow supply-chain defect: the scan replaced the trusted workflow dependency lock with a same-repository PR-head lock before provider credentials later reached the installed scanner. Exact head 975a9e4 removes that operation, keeps installation on the trusted-source lock, and retains only the current default-branch smoke marker needed for bootstrap compatibility. Both old-main and exact-head bounded smoke contracts pass. Validation: 1396 passed, 1 skipped, 16 subtests; focused Strix set 40 passed plus 16 subtests; shell syntax and git diff --check passed. No gate was weakened: incomplete provider scans and reported vulnerabilities remain non-passing.

[seonghobae]

Exact-head follow-up for 7011fee: removed the redundant direct-OpenAI branch from STRIX_FALLBACK_MODELS so direct-OpenAI uses only the final empty default after bounded same-model retries. Updated the shell contract test and Python regression assertion to enforce that invariant. Verified locally: 16 targeted tests passed; bash -n passed; actionlint on .github/workflows/strix.yml passed; git diff --check passed; filtered Strix quick gate exited 0. Please review this exact head.

[seonghobae]

@opencode-agent review Exact head: 7011fee. Review the complete changed diff and report substantive findings with file/line evidence.

[seonghobae]

Current-head check observation for 7011fee: scan-pr-queue run 32693700001 was cancelled when newer run 32694141371 superseded it; the newer exact-head scan is queued. No source failure is present. This remains normal scheduler progress, not D1-D6 guarded-merge evidence.

[seonghobae]

OpenCode current-head follow-up: exact head 7011fee adds the explicit empty direct-OpenAI fallback regression test and removes the redundant direct-provider branch from STRIX_FALLBACK_MODELS. Local verification on this exact tree: pytest focused Strix tests 19 passed, bash -n scripts/ci/test_strix_quick_gate.sh, and actionlint .github/workflows/strix.yml. No unresolved review threads; required checks remain pending, and the historical changes-requested review still means no merge is authorized.

[seonghobae]

Exact current head 7011fee275eaa257ce491efb4812dd3e98ed649e remains source-clean and all review threads are resolved. I downloaded the failed Strix artifact from run 32693700056:

• primary nvidia_nim/nvidia/nemotron-3-super-120b-a12b returned HTTP 429 rate limit on retries;
• NIM fallback nvidia_nim/nvidia/llama-3.3-nemotron-super-49b-v1.5 produced a zero-finding report but the gate retained the earlier provider-failure signal and correctly failed closed;
• direct fallback openai-direct/gpt-5.6-luna then returned HTTP 404.

The artifact proves provider availability/quota failure, not a source vulnerability. No scan result was promoted to success. A failed-job rerun was requested; its new queue is tracked separately. No merge/readiness claim until a fresh same-head authoritative Strix result and protected approvals exist.

[seonghobae]

Exact-head update: 94f56fd2cc269fffcc55c453e22eca5676f97b1b

Root-cause repair for the observed cross-provider Strix failure:

• NIM rate-limit/provider exhaustion remains fail-closed.
• Direct OpenAI fallback now receives a trusted explicit https://api.openai.com/v1 API-base file, alongside the already-separated OpenAI fallback credential, so it cannot inherit the exhausted NIM/OpenRouter/GitHub Models endpoint.
• Added an exact resolver regression test and updated doctoring/CHANGELOG evidence.

Exact-head local verification on this tree: 17 Strix fallback tests; 98 related Python contract tests; Bash syntax; actionlint; and git diff --check passed. The full shell harness was also attempted and exposes a pre-existing nested PR-head fixture/path-safety mismatch; no test or gate was weakened.

@opencode-agent Please perform a new substantive review against this exact head only, including changed-file walkthrough, fallback credential/API-base boundary, security impact, and test evidence. Do not reuse predecessor-head evidence.

[seonghobae]

Exact-head repair update: d6c34c59f18e959596ddc18f2c169d312e571758 (parent 94f56fd2cc269fffcc55c453e22eca5676f97b1b).

• RED: a complete zero-finding scan whose target narrative mentioned OpenAI on one line and documented Fatal/Denied/Warn/Warning labels on another was falsely classified as provider infrastructure failure.
• Fix: require an LLM-provider marker and the failure word on the same physical non-allowlisted line.
• GREEN: the new negative control and existing Fatal/Warning/Denied positive controls pass the focused shell harness; genuine same-line provider signals remain fail-closed.
• Syntax and whitespace checks pass.

All predecessor reviews/checks are historical. Current hosted runs are queued/in progress and therefore non-passing.

@opencode-agent Please perform a new substantive formal review against exact head d6c34c59f18e959596ddc18f2c169d312e571758 only. Validate the same-line authentication boundary, negative target-output spoof control, genuine provider-failure controls, and complete changed diff; do not reuse predecessor verdicts.

[seonghobae]

Final exact-head follow-up: a73831f60f83a61df95dbcb6999094fab80bb352.

The first full-harness pass correctly exposed a regression in the initial narrowing: an exact HF advisory with a malicious appended Fatal suffix could pass because HF Hub was not in the same-line provider context. That predecessor head is rejected.

The final minimal repair includes the exact HF Hub advisory context in the same-line authentication boundary. Focused GREEN now covers: clean target narrative, genuine litellm Fatal, openai Warning, anthropic Denied, and altered HF-advisory suffix. The clean narrative passes; all four authenticated/altered provider signals remain fail-closed.

All hosted checks and reviews for earlier heads are historical. New exact-head workflows are pending. @opencode-agent review this exact head only, including the altered-advisory negative control.

[seonghobae]

Disposition for current informational threads on exact head a73831f60f83a61df95dbcb6999094fab80bb352:

• PRRT_kwDOS_C14s6bnVv- (console warning context): confirmed intentional. Bare target/repository narrative is no longer provider evidence; the same physical line must carry an authenticated LLM-provider marker (or exact HF Hub advisory context) and the failure word. Specific timeout/rate-limit/token/connection/service/model classifiers and report-artifact detection remain unchanged. Focused TDD covers clean split-line narrative, genuine provider signals, and altered HF-advisory suffix.
• PRRT_kwDOS_C14s6bnVxn (status follow-up token): confirmed intentional credential isolation. The follow-up first uses the exchanged target-app token, then the two explicit central credentials. Its GITHUB_TOKEN is read-only, so it cannot accidentally broaden target writes. If none can publish, no strix commit status is fabricated; target branch protection remains blocked/authoritative. A complete successful scan run remains source evidence, while an absent required status is still non-passing governance evidence. test_strix_scan_cannot_read_target_pr_or_publish_status and the trusted required-workflow smoke pin this boundary.

No source change is justified by either informational observation.

[seonghobae]

Exact-head remediation on 4fb737a: fixed the Strix Changed Path Quality CI trigger so changes to requirements-strix-ci.txt, requirements-strix-ci-hashes.txt, and tests/test_strix_severity_identifier_boundary.py rerun the exact-head quality contract. Added regression assertions for all four contract inputs. Focused verification: 16 passed; Strix shell syntax; interrogate docstring coverage 100 percent; git diff --check passed. Please publish a fresh independent substantive review and required hosted checks for this exact head. Previous-head evidence is stale; no gate was weakened and no bypass was used.

[seonghobae]

Exact-head review disposition for 4fb737a6c44ad3fc73270f55ff8a5abb415f1e3c:

• requirements-strix-ci.txt and requirements-strix-ci-hashes.txt are now explicit changed-path quality trigger inputs.
• tests/test_strix_severity_identifier_boundary.py is now an explicit trigger input.
• tests/test_strix_workflow_dependency_hashes.py pins all three paths so this cannot silently drift.
• Focused current-tree verification: 16 tests and 16 subtests passed; both contract files compile.

This addresses threads PRRT_kwDOS_C14s6bnfnn and PRRT_kwDOS_C14s6bnfpK. Hosted exact-head workflows remain authoritative and non-passing until terminal.

[seonghobae]

Exact-head local verification completed for 4fb737a: full pytest 1408 passed, 1 skipped, 16 subtests; focused trigger contract 16 passed; interrogate docstring coverage 100 percent; shell syntax, compileall, and git diff --check passed. Hosted current-head workflows and independent approval remain pending, so this PR stays on the normal protected path.

[seonghobae]

Hosted exact-head verification is now available for 4fb737a6c44ad3fc73270f55ff8a5abb415f1e3c: Strix Changed Path Quality run 32705249918, job 97364828647, checked out the exact submitted SHA, ran 1,408 tests·16 subtests, and recorded test_strix_quick_gate: PASS. All review threads are resolved.

The remaining queued security/SBOM workflows and absence of an exact-current-head qualifying formal verdict are non-passing; no merge is requested until those become authoritative.

Current-head review loop

• Pull request: fix(strix): make Azure and cross-provider fallbacks executable #1263
• Exact head checked: ab3d764547082e1b55b6257cc1cd9aa5d951fa30
• Current source inspection confirms the earlier cross-provider fallback finding is resolved: the trusted quick gate validates and reads STRIX_OPENAI_FALLBACK_KEY_FILE, selects the dedicated key for non-direct primaries, and uses the separately provisioned direct OpenAI API-base file. The changed-path trigger also contains the severity-boundary regression test.
• Current hosted feature Checks are successful; the remaining review state is stale/absent current-head approval rather than an unaddressed source defect.

Please publish a fresh substantive review for this exact head and replace stale review state through the normal review workflow. Do not merge until the protected approval gate is current.

Exact-head Strix RCA for ab3d764547082e1b55b6257cc1cd9aa5d951fa30:

• The source checks completed the scan with Vulnerabilities 0, but no authoritative report artifact was produced.
• NVIDIA NIM emitted provider infrastructure/failure-signal output; the configured openai-direct/gpt-5.6-luna fallback then failed with 404 page not found.
• This is provider/control-plane evidence, not a confirmed source vulnerability in this PR. The direct-OpenAI API-base repair is being handled by the related exact-head PR fix(strix): route direct-OpenAI fallback models to the OpenAI platform endpoint #1295; predecessor failure evidence is not reused as approval.
• Required checks are otherwise substantially green, but Strix is failing closed, coverage-source-tree and remaining security checks are pending, and current-head independent approval is absent.

Decision: WAIT_AND_REMEDIATE. No force merge and no merge until the provider route is repaired and fresh exact-head Strix evidence plus substantive approval are available.
