Negative test: BSD adapter must reject unsupported M6 promotion

[mdheller]

Purpose

This is an intentional failing PR for SocioSphere proof-apparatus validation.

It verifies that the BSD adapter cannot promote BSD-M6-002-four-descent-named-primes without the four-descent gates passing and without SocioSphere controller promotion.

Expected result

The Proof apparatus continuous validation check must fail.

Expected failure class:

• repo-local self-promotion, or
• invalid claim.state = promoted.

Success condition

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

Do not merge.

Tracking issue: #4

Verification result: expected failure confirmed.

Run 25681091997 failed at strict adapter validation for the intended reason:

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

The run materialized the PR head:

domain_ref=refs/pull/5/head
domain_sha=67159cd3abbbe978beb136fb517d8a21740c29dc

The printed materialized adapter snippet showed the intended mutation:

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

Failure artifacts were uploaded and the job log printed the artifact manifest, strict-validation log, exit code, failure context, and materialized adapter snippet.

Status: this negative-test PR succeeded by failing. Do not merge.
