Implements the missing yieldOracle dependency for FCMVault. FUSDEV is itself an ERC4626 vault whose underlying asset is PYUSD0, so its convertToAssets exchange rate IS the yield token price in loan-token terms, with both tokens' decimals already embedded. The oracle is a thin adapter scaling that rate to Morpho's IOracle 1e36 convention -- the same shape as Morpho's own ERC4626 oracle adapters. NAV pricing cannot be moved by trading against the thin FlowSwap pool (no TWAP machinery needed); it is only as trustworthy as FUSDEV's own share accounting, and reflects redemption value rather than the pool's executable swap price -- documented in the contract NatSpec. Unit tests cover rate scaling across decimal regimes and constructor validation; fork tests against the live FUSDEV vault run when FLOW_MAINNET_RPC_URL is set and skip otherwise.

Adds a committed deployments/mainnet.json (pinning the existing Morpho WETH/PYUSD0 market params and FlowSwap pools) and four forge scripts, all chain-id-guarded and dry-runnable by dropping --broadcast: - Status: read-only report on market, pools, oracle prices, balances; survives a reverting (stale) Pyth market oracle and reports it - SeedMarket: supply PYUSD0 liquidity to the existing empty market - DeployVault: deploy YieldTokenOracle (when not yet configured) and FCMVault, grant EARLY_ACCESS_ROLE, set MAX_TVL; aborts on missing market/liquidity/pool mismatches - LiveCheck: real deposit -> redeem integration check with a round-trip tolerance, config-free (reads everything from the vault) ConfiguredScript is the shared base (config load, market id, pool and market pre-flight checks). Replaces the bare env-var FCMVault.s.sol. foundry.toml gains deployments/ read permission and the flow_mainnet RPC endpoint. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Make targets (manual only, never run from CI): mainnet-status, mainnet-seed-market, mainnet-deploy, mainnet-check, each with a -dry variant that fork-simulates without broadcasting, plus mainnet-fork-test for the oracle fork tests. A labeled slot is left for the Cadence VaultRebalancer (PR #38) once it merges. solidity/README.md gains the full runbook (status -> seed -> deploy -> check, always dry-run first), script/env reference, post-deploy record-keeping steps, and key-handling guidance. Root README gains a Deployment section with the deployed contracts table and market id. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Runs the entire production sequence -- SeedMarket -> DeployVault -> LiveCheck -- against an anvil fork of live mainnet, with state carried between steps, real Morpho/FlowSwap/Pyth contracts, zero real funds, and no PRIVATE_KEY (uses anvil's public dev account, funded with WETH/PYUSD0 via impersonated transfers from the FlowSwap pools). If the Pyth WETH/USD market oracle is stale (it reverts with StalePrice after 1h without a push, the current live state), the script posts a fresh signed update from Hermes -- the same permissionless remedy an operator would use on real mainnet. Cleanup removes the rehearsal's broadcast/*/747/ records so they cannot masquerade as real deployment records; the script refuses to start if uncommitted broadcast records are already present. Verified end-to-end: seed 50k PYUSD0, deploy oracle + vault, live check round-trip 9997 bps. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
