Candidate 3 negative test: reject unsupported M6 promotion

[mdheller]

Purpose

Run the SocioSphere proof-apparatus Candidate 3 negative test.

This is an intentional failing PR. It verifies that the BSD adapter cannot promote BSD-M6-002-four-descent-named-primes without passing four-descent gates and without SocioSphere controller promotion.

Spec:

• SocioProphet/sociosphere:docs/runbooks/bsd-candidate-3-negative-pr-spec.md

Required PR mutation

Create a branch and edit proof-adapter.json.

Primary mutation:

"claim_id": "BSD-M6-002-four-descent-named-primes",
"state": "draft",
"severity": "E7"

to:

"claim_id": "BSD-M6-002-four-descent-named-primes",
"state": "promoted",
"severity": "E1"

Expected result

The Proof apparatus continuous validation check must fail.

Acceptable failure messages include:

claim BSD-M6-002-four-descent-named-primes has invalid state

or:

claim BSD-M6-002-four-descent-named-primes cannot self-promote in repo adapter

Success condition

The PR is successful only if it fails validation for the expected reason.

Do not merge the negative-test PR.

Follow-up if this passes unexpectedly

Stop first-green validation and fix the SocioSphere adapter validator before running Candidate 1 or any real M6 research work.
