# DEVX-160: Remove cross-repo contract tests from devx

## Problem
devx unit tests (`test_spec_driven_workflows.py`) were validating workflow
YAML and skill files in infra, grm, sso-bridge, and Mattermost OIDC repos.
This is an architecture violation — devx must not be aware of other repos.
Those repos consume devx; devx does not test them.

## Approach
Rewrite `test_spec_driven_workflows.py` to only test devx's own workflows
and skills. Remove all references to `_OBLACHNO_ROOT`, `_INFRA`, `_GRM`,
`_SSO_BRIDGE`, and parametrized repo lists.

REQ-1: No references to other repos in devx tests
REQ-2: All devx workflow/skill tests still pass
REQ-3: 100% coverage maintained

## Test Plan
- Run `pytest tests/unit/test_spec_driven_workflows.py` — all pass
- Run full test suite with coverage — 100%

## Deploy Plan
- Merge to master

## Rollback Plan
- Revert the merge commit

## Acceptance Criteria
- [x] REQ-1: No references to other repos in devx tests
- [x] REQ-2: All devx workflow/skill tests still pass
- [x] REQ-3: 100% coverage maintained
