# CTO Core Route Admission Guard Closeout

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

Core Route Admission Guard.

## Workboard

- `CTO-WORK-089`
- `CTO-WORK-090`
- `CTO-WORK-091`
- `CTO-WORK-092`

## Result

- status: validated
- core_route_admission_status: not_admitted
- guard_status: blocked
- blocked_reason: active_or_conflicting_core_work_present
- do_not_touch_other_agent_work: true
- ready_for_core_route_review: true
- recommended_next_decision: open_governed_core_prd_route
- next_allowed_action: wait_or_open_later_core_route_when_idle
- idle_governed_core_route_required: true
- no_active_conflicting_core_worktree_required: true
- runtime_default_activation: false
- core_promotion_status: not-promoted
- No Core mutation occurs.
- No Core reservation occurs.
- No Core promotion occurs.
- Do not mutate `../core/`.
- Runtime default activation remains false.
- Do not activate Case as default backend.
- This closeout does not authorize another Case run.

## Evidence References

- `CTO-WORK-085`
- `CTO-WORK-086`
- `CTO-WORK-087`
- `CTO-WORK-088`
- `CTO-WORK-089`
- `CTO-WORK-090`
- Core Promotion Decision Packet remains child-local.
- Core route admission is blocked until future read-only checks pass.
- S135 conflict avoidance remains required when `CORE-WORK-172` or `core/worktrees/core-keyvault-authmd-promotion-135` is active.

## Validation

- `python3 tools/validate_cto_child.py`: required
- `python3 /home/svrnty/workspaces/cortex-os/core/tools/check_s69_caveman_prose_discipline.py`: required before final claim

## Decision

Do not touch other agent work. Do not open or mutate a Core route from CTO while active or conflicting Core work exists. `recommended_next_decision: open_governed_core_prd_route` remains candidate-only until the guard passes.
