# 16 — DOC: US-006 reconciliation note

## What to build

Reconcile stale US-006 (Solana testnet stake contracts) with ADR-0015/0016 devnet custodial settlement. Issue `docs/issues/06-solana-stake-and-settlement.md` says "never devnet"; ADR-0015 explicitly targets devnet mock-USDT.

Also reconcile legacy fraud issues with the alpha-hardening fraud arc:

- `docs/issues/07-fraud-detection-slash.md` — on-chain stake slash model superseded by pending-balance forfeiture + TOPLOC (ADR-0018)
- `docs/issues/34-forfeiture-penalty.md` — partially implemented; remaining fraud work lives in `.scratch/alpha-hardening/issues/06-fraud-toploc-integration.md` through `10-fraud-penalty-calibration-wiring.md`

## Acceptance criteria

- [ ] Add reconciliation comment atop `docs/issues/06-solana-stake-and-settlement.md` (Status: superseded for alpha — see ADR-0015, issue 33/34)
- [ ] Add **superseded** banner atop `docs/issues/07-fraud-detection-slash.md` → ADR-0018 + issues 06–10
- [ ] Add **superseded for remaining scope** banner atop `docs/issues/34-forfeiture-penalty.md` → ADR-0018 + issues 06–10 (note done items: basic forfeiture wired)
- [ ] Update `docs/prd.json` US-006 description footnote if present
- [ ] Cross-link ADR-0015 devnet decision
- [ ] No production code changes
