# CTO Case Agent Protocol Blocker
|
|
|
|
Local planning SOT only. Not a Core Protocol. Not active Core authority.
|
|
|
|
## CTO-WORK-028 - Case Agent Result Protocol Blocker
|
|
|
|
Status: blocked.
|
|
|
|
Record the first admitted real Case Stage 2 run after OpenAI Codex model admission.
|
|
The run proves that provider/model admission now reaches Case execution, but does
|
|
not prove Stage 2. Case failed before producing a workspace diff because its
|
|
implementer agent result did not satisfy the Case result-envelope contract.
|
|
|
|
The later admitted Qwen local run reproduced the same result-envelope failure
|
|
after Case process start. This makes the active blocker the Case agent-result
|
|
protocol seam, not model admission.
|
|
|
|
Acceptance:
|
|
|
|
- Real Case Stage 2 remains blocked until Case produces a Harness Evidence Interface pass report.
|
|
- The admitted provider/model pair evidence includes `openai-codex` / `gpt-5.5` and `qwen-local` / `qwen3.6-35b-a3b`.
|
|
- The admission files remain `.sot/03-PROTOCOLS/CTO-CASE-MODEL-PROVIDER-ADMISSION.openai-codex-gpt-5.5.json` and `.sot/03-PROTOCOLS/CTO-CASE-MODEL-PROVIDER-ADMISSION.qwen-local-qwen3.6-35b-a3b.json`.
|
|
- Evidence must show `case_process_started: true` before this blocker is accepted as the current blocker.
|
|
- Evidence must show `case_model_admission_status: admitted`.
|
|
- Evidence must show no target repository path was inspected or copied.
|
|
- Evidence must show no workspace patch was produced.
|
|
- Evidence must show tests did not pass.
|
|
- The next implementation route must happen through the Hermes CTO harness seam, a Case-compatible provider adapter seam, or an external compatibility layer.
|
|
- The next implementation route must not mutate Cortex Core, vendor Case source, or external developer repositories.
|
|
- No real-repo, copied-repo, sandbox-repo, owned-repo, default-candidate, or Core promotion stage may use this failed run as pass evidence.
|
|
|

## Current Interpretation
|
|
|
|
This is a protocol compatibility blocker, not a provider approval or model
|
|
admission blocker.
|
|
|
|
Two admitted provider/model paths reached Case. Case then failed because the
|
|
implementer agent did not return output framed by the Case `AGENT_RESULT`
|
|
delimiter contract. The evidence does not prove whether the defect is Case
|
|
provider configuration, provider adapter behavior, model output framing, or
|
|
harness invocation shape.
|
|
|
|
## Narrowed Interpretation - 2026-06-01
|
|
|
|
Hermes commit `5db23c7 Fail closed on Case Codex auth gap` narrows the current
|
|
OpenAI Codex path blocker.
|
|
|
|
The current known OpenAI Codex blocker is an auth-bridge gap:
|
|
|
|
- Case's pipeline SDK path constructs its Pi Agent runtime directly.
|
|
- That path does not pass Pi AuthStorage OAuth headers into `streamSimple`.
|
|
- Pi env API-key lookup does not map `openai-codex` to an environment API key.
|
|
- Hermes now blocks `openai-codex` before `case_process_started` unless an explicit non-vendor auth bridge is proven.
|
|
|
|
This does not prove that any local provider path passes Stage 2. It only prevents
|
|
repeating the misleading malformed-output run for the `openai-codex` path.
|
|
|
|
## Required Next Route
|
|
|
|
The next useful route is a small Case agent protocol compatibility investigation.
|
|
It should answer only this question:
|
|
|
|
```text
|
|
What minimal non-vendor seam makes admitted Case execution return the required
|
|
AGENT_RESULT envelope and produce a Stage 2 artificial fixture diff?
|
|
```
|
|
|
|
Allowed next actions:
|
|
|
|
- Inspect Case provider adapter behavior read-only.
|
|
- Inspect Hermes CTO Case invocation behavior.
|
|
- Add fail-closed classification in Hermes CTO harness if needed.
|
|
- Add a compatibility shim only outside vendor Case source.
|
|
- Admit and test the existing Pi local provider id `qwen-local` only through the Harness Evidence Interface.
|
|
- Re-run real Case Stage 2 only after a specific protocol compatibility change exists.
|
|
|
|
Forbidden next actions:
|
|
|
|
- Do not edit `/tmp/workos-case` as the durable solution.
|
|
- Do not mark Stage 2 validated from this run.
|
|
- Do not promote Case to copied repo, sandbox repo, owned repo, or default candidate.
|
|
- Do not write provider secrets to SOT, argv, task files, backend logs, reports, traces, or commits.
