Lock Feeder — wire dollars in

This is the missing production piece: a verified foreign lock before Worldlight credits PIX.

Paths

Venue	Lock surface	Receipt
USDC (Ethereum)	contracts/PixelUsdcLock.sol (+ MockUSDC.sol)	Locked event → LockReceipt
USDC (CI / local)	LocalUsdcRail in lock-feeder.ts	same receipt shape
Bank wire	BankWireAttestor (hash-OTS)	signed wire claim → LockReceipt

Pipeline

lock USDC / attest wire
        ↓
verify LockReceipt (rail or attestor)
        ↓
LockFeeder.feed → PreparedIngress
        ↓
illuminateIngress (bridge escrow → Personal Source)
        ↓
LockFeeder.consume (no double shine-in)

Solidity

// approve MockUSDC, then:
PixelUsdcLock.lock(5_000_000, "pix1…", salt); // $5 USDC (6 decimals)

Relayer watches Locked, builds receipt, calls Pixel One.LockFeeder.feed.

Self-custody

Feeder never holds Pixel seeds. pixelRecipient is always a pix1… Personal Source.
