CTO Case Spark Endpoint Config Issues

Local planning SOT only. Not a Core Protocol. Not active Core authority.

CTO-WORK-030 - Spark Local Provider Endpoint Config

Status: blocked.

Supply explicit Spark OpenAI-compatible endpoint config for the selected qwen-local / qwen3.6-35b-a3b Case path, without storing endpoint secrets in SOT or commits.

Acceptance:

• CTO_HARNESS_CASE_LOCAL_BASE_URL is supplied at runtime for the real Qwen Case Stage 2 retry.
• Missing endpoint config blocks before case_process_started.
• Missing endpoint config writes backend/provider-local-config-unavailable.txt.
• Endpoint values are not written to SOT, task file, argv, backend logs, report, trace, generated config, or commit.
• Harness report proves case_model_provider: qwen-local.
• Harness report proves case_model: qwen3.6-35b-a3b.
• Harness report proves case_model_admission_status: admitted.
• Harness report proves no fallback to anthropic or claude-sonnet-4-6.
• Real Case Stage 2 pass evidence exists only through the Harness Evidence Interface.
• A configured endpoint alone does not validate CTO-WORK-016, CTO-WORK-020, CTO-WORK-022, or CTO-WORK-028.
• No Target Repository path may be inspected or copied.
• Same-run fake baseline comparison remains required for any pass claim.
• CTO-WORK-016 remains blocked until real Case Stage 2 pass evidence exists.
• CTO-WORK-022 remains blocked until explicit endpoint config and real Case Stage 2 pass evidence exist.

Blocked by:

• Real Case Stage 2 pass evidence.
• Case agent-result protocol compatibility.

Current evidence:

• Non-secret readiness check on 2026-06-01 showed CTO_HARNESS_CASE_LOCAL_BASE_URL=missing.
• Existing Hermes harness blocks missing local provider config before case_process_started.

Spark vLLM Runtime Evidence - 2026-06-01

• Spark1 was reachable over Tailscale and SSH.
• A vLLM Docker container exposed an OpenAI-compatible model route for qwen3.6-35b-a3b.
• The Spark endpoint value was supplied only through runtime environment and is not recorded in this SOT.
• The standard command class was harness/evals/case-qwen-loop.sh --json.
• Run artifact directory: /home/svrnty/.hermes/profiles/cto-planb/harness-runs/20260601T022535Z-r1-string-slugify-2731603.
• Report status: fail.
• Backend: case.
• Backend exit code: 1.
• Case process started: true.
• Case model provider: qwen-local.
• Case model: qwen3.6-35b-a3b.
• Case model admission status: admitted.
• Source admission status: not_admitted.
• Failure reason: case agent result protocol failed.
• The harness recorded no changed files.
• The patch artifact was empty.
• Tests failed because the artificial fixture bug remained unchanged.
• This proves the Spark endpoint blocker was crossed for one runtime attempt.
• This does not validate CTO-WORK-016, CTO-WORK-020, CTO-WORK-022, or CTO-WORK-028.
• Current active blocker is the Case agent-result protocol seam.

Hermes Case Qwen Loop Evidence - 2026-06-01

• Hermes commit: 6c453ee Add Case Qwen loop entrypoint.
• New command: harness/evals/case-qwen-loop.sh --json.
• The command sets fixed non-secret Case/Qwen routing knobs for qwen-local / qwen3.6-35b-a3b.
• The command requires CTO_HARNESS_CASE_BIN and CTO_HARNESS_CASE_MODEL_ADMISSION_FILE from the caller.
• The command delegates to run-case.sh --engine case so runtime artifacts keep the Harness Evidence Interface shape.
• The command must not print CTO_HARNESS_CASE_LOCAL_BASE_URL.
• Focused validator passed: python3 harness/runner/validate-case-provider-adapter.py --harness-root harness --json.
• Focused validator artifact: /home/svrnty/.hermes/profiles/cto-planb/harness-runs/20260601T022022Z-r1-string-slugify-2694767.
• Pre-merge aggregate validator passed: harness/evals/health.sh --json.
• Pre-merge aggregate validator artifact: /home/svrnty/.hermes/profiles/cto-planb/harness-runs/20260601T022036Z-r1-string-slugify-2695716.
• Post-merge aggregate validator passed: harness/evals/health.sh --json.
• Post-merge aggregate validator artifact: /home/svrnty/.hermes/profiles/cto-planb/harness-runs/20260601T022100Z-r1-string-slugify-2697229.
• CTO-WORK-030 remains blocked until CTO_HARNESS_CASE_LOCAL_BASE_URL is supplied at runtime and a real Stage 2 pass report exists.
