SG-1: shared bones and equipment in SoroCastl

SG-1 signed receiver, lifetime wallet, personal equipment and verified castle rewards.

• 1 bone = 10 personal gold talers. Purchases and refunds use their original server prices.
• First school login pulls lifetime earnings. A confirmed SRL battle queues a win or loss award.
• Existing team construction and repair points stay separate from the personal wallet.
• The wallet store must be persistent and have one writer.

Checked: coin wallet tests and the full existing test suite. Depends on API v2 and db-git SG-1.

2026-10-02 rollout: reuse existing deployment, no new game service or pipeline. All 574 Node 22 tests passed. Deployment and delivery remain disabled until the owner provisions the SoroCastl server; the Sites demo is not a substitute.
