Context

DOUB-primary buy router with Kumbaya multi-asset entry. Parent epic: #238.

Relevant files

  • Refactor contracts/src/TimeCurveBuyRouter.sol → TimeArenaBuyRouter.sol
  • contracts/src/fixtures/AnvilKumbayaFixture.sol
  • docs/integrations/kumbaya.md
  • frontend/src/lib/timeCurveKumbayaSingleTx.ts

Acceptance criteria

  • DOUB direct: buy(charmWad) pulls DOUB
  • CL8Y: swap via CL8Y/DOUB Kumbaya pair → DOUB → buy
  • ETH / USDm: multi-hop to CL8Y → DOUB
  • Single-tx router: buyViaKumbaya targets DOUB output equal to gross DOUB need
  • Balance-delta ingress preserved (#123)
  • Chain-time swap deadlines (#83)

Verification checklist

  • Forge fork/local: each pay asset path
  • bash scripts/verify-timecurve-buy-router-anvil.sh replaced with arena equivalent

Implementation summary

  • TimeArenaBuyRouter.sol (DOUB exactOutput + buyFor); stub scripts/verify-time-arena-buy-router-anvil.sh.

Acceptance criteria

  • Router contract for ETH/stable/CL8Y → DOUB
  • Full Anvil fork matrix (deploy script follow-up)

Verification checklist

  • Run verify script after Kumbaya fixture deploy

Verification complete (#251)

Verified TimeArenaBuyRouter on the live Anvil stack (no infra restart). Deployed Kumbaya fixtures on existing Anvil (DeployKumbayaAnvilFixtures), merged registry + ran full verify script. Pushed to main as 16b3278.

What changed

  • Forge: test_buyViaKumbaya_cl8y_creditsAlice, test_buy_doub_direct_pullsFromWallet, new VerifyTimeArenaBuyRouterAnvil.t.sol (fork ETH/USDM/CL8Y matrix on deployed Anvil)
  • Scripts: verify-time-arena-buy-router-anvil.sh — no longer kills running Anvil; fixed cast bool/arenaStart parsing; runs fork matrix; verify-timecurve-buy-router-anvil.sh → deprecated wrapper
  • Docs: docs/integrations/kumbaya.md Arena v2 section, INV-TIME-ARENA-BUY-ROUTER updated, skills/play-time-arena-doub/SKILL.md cross-link

Acceptance criteria

  • DOUB direct: TimeArena.buy(charmWad) pulls DOUB — TimeArenaBuyRouter.t.sol::test_buy_doub_direct_pullsFromWallet
  • CL8Y: CL8Y/DOUB single-hop → buyFor — unit + fork tests
  • ETH / USDm: multi-hop → DOUB — unit + fork tests
  • Single-tx buyViaKumbaya targets gross DOUB need
  • Balance-delta ingress (#123) — test_stableIngressParity_revertsOnFeeOnTransfer
  • Chain-time swap deadlines (#83) — test_buyViaKumbaya_revertsExpiredDeadline

Manual verification checklist

  • bash scripts/verify-time-arena-buy-router-anvil.sh on Anvil with YIELDOMEGA_DEPLOY_KUMBAYA=1 if router unset
  • cd contracts && forge test --match-contract TimeArenaBuyRouter -q
  • YIELDOMEGA_FORK_VERIFY=1 FORK_URL=http://127.0.0.1:8545 YIELDOMEGA_TIME_ARENA=<proxy> forge test --match-path test/VerifyTimeArenaBuyRouterAnvil.t.sol
  • /arena ETH/USDM pay when VITE_KUMBAYA_TIME_ARENA_BUY_ROUTER matches onchain router
  • Indexer ingests BuyViaKumbaya after registry lists TimeArenaBuyRouter

All automated criteria from the issue body and prior comment pass. Closing.
