# CTO Architecture Brief Closeout PRD
|
|
|
|
Local planning SOT only. Not a Core Protocol. Not active Core authority.
|
|
|
|
## Problem Statement
|
|
|
|
`CTO-WORK-001` remains `candidate` even though later validated CTO work now proves the architecture thesis as a child-local planning surface: Cortex governs, Hermes controls, CTO routes, Harness proves, Case executes after proof, and Target Repositories stay owned.
|
|
|
|
Leaving the first brief as candidate makes the WORKBOARD look less true than the actual proof ladder.
|
|
|
|
## Solution
|
|
|
|
Close `CTO-WORK-001` as validated by referencing later evidence instead of changing authority.
|
|
|
|
The closeout must say the brief is validated only as child-local architecture planning. It must not claim Core promotion, Case runtime default activation, or real production delegation readiness.
|
|
|
|
## Scope
|
|
|
|
- Mark the original architecture brief as validated.
|
|
- Record the exact evidence chain that validates the brief thesis.
|
|
- Keep Case as candidate-default eligible only, with runtime default activation false.
|
|
- Keep the CTO workspace child-local.
|
|
- Keep Hermes as control and replay surface, not authority.
|
|
|
|
## Non-Goals
|
|
|
|
- Do not implement a new backend.
|
|
- Do not activate Case as runtime default.
|
|
- Do not mutate Hermes Runtime, Cortex Core, Case source, vendor source, external developer repositories, or Target Repositories.
|
|
- Do not create a new Core Protocol.
|
|
- Do not reopen provider/model policy.
|
|
|
|
## Acceptance Criteria
|
|
|
|
- `CTO-WORK-001` status is `validated`.
|
|
- Closeout evidence references Stage 1 through Stage 6 validation.
|
|
- Closeout evidence references `CTO-WORK-043` Stage 6 candidate-default comparison.
|
|
- Closeout evidence references `CTO-WORK-045` Hermes Control Surface validation.
|
|
- Closeout says Case remains candidate only and runtime default activation remains false.
|
|
- Local CTO validator checks the closeout PRD and issue artifact.
|
|
|
|
## Validation
|
|
|
|
Run:
|
|
|
|
```bash
|
|
python3 tools/validate_cto_child.py
|
|
```
|
|
|
|
## Risks
|
|
|
|
- Overclaiming: mitigated by saying this is planning validation only.
|
|
- Authority drift: mitigated by keeping Core promotion status `not-promoted`.
|
|
- Default drift: mitigated by saying runtime default activation remains false.
|
|
|
|
## Success Definition
|
|
|
|
The CTO WORKBOARD has no stale candidate architecture item, and the original brief points to the validated proof ladder without granting new authority.
