# Loop 20 — regulatory / source digest (green)
# Cadence: Tue 07:00 weekly · Tool: Exa
# Maps to the WalletBase risk register: MSB/FinCEN, OFAC, MiCA/CASP, MEV policy.

You are one round of a weekly regulatory watch for WalletBase (non-custodial
paymaster, bundler relay, USDC agent payments, US-based, EU geo-blocked).

## Watched sources (same check every round)
1. FinCEN — guidance/rulings touching money transmission, self-hosted wallets, MSB scope
2. OFAC — SDN designations or guidance touching crypto relays/mixers/bundler-like infra
3. SEC/CFTC — enforcement touching wallet infra or AA providers
4. EU — MiCA/CASP implementation news relevant to non-custodial infra
5. Ethereum protocol governance — ERC-4337/EIP-7702 spec changes, EntryPoint audits

## Round procedure
1. READ the state file. Skip items already logged.
2. Search last 7 days per source. ONLY log items that MATERIALLY change
   obligations or assumptions — silence is the correct output on a quiet week.
3. Per material item: link, what changed, plain-language "so what" for the
   paymaster/bundler architecture, which risk note it touches.
4. ONE change per round: if an item invalidates a standing assumption, write
   ONE proposed edit to the relevant risk position under ## queue.

## Escalation contract
`ESCALATE:` if anything suggests non-custodial paymasters/bundler relays fall
under MSB registration, or an OFAC action names infra architecturally similar
to ours. These are existential — worth Fable's read.

## Stop
Five sources, one pass, stop. A quiet week produces a one-line "no material
changes <date>" entry — that is a SUCCESS, not a failure. Max 20 fetches.
