Map the Eureka pipeline state cuts

Imagination's cut map, built from probes:
1. Re-pin CultLib: 12 load_envelope sites; core 154/154 at the new pin.
2. One profile-parameterized commit owner.
3. The pipeline document set, lease, admission, queries, and a merge command.
4. The eureka-state stdio MCP package.
5. Skill wiring.
6. A proof campaign on the CultRecordRefFormatter follow-ups.
7. voidbot projection.

Five operator questions are open. The target now drops the claim that the
store merges in git, and records that voidbot indexes only default branches.
