Deploy Phase 2 (TGE)

DeployPhase2.s.sol implements the Phase 2 token generation event. Code shipped, never deployed. The full design is in the repo's Phase 2 doc.

#Guards

• CONFIRM_MAINNET=I_UNDERSTAND
• CONFIRM_SEAT_TGE=I_UNDERSTAND
• Chain 4663, official USDG, OWNER == broadcaster.

#What it deploys / does

1. SeatToken — 1,000,000,000 $SEAT (18 decimals) minted once to SEAT_HOLDER (defaults to OWNER). No mint function exists after construction.
2. StakingPool — $SEAT staking with an accUsdgPerShare reward accumulator.
3. LpLocker — locks a Uniswap v3 position NFT for ≥ 365 days.
4. Extra desks — LEADER_2 and LEADER_3 each get a desk if set; unset leaders are skipped.
5. Fee wiring — sets each vault's stakerRecipient to the staking pool, activating the 70/20/10 leader/protocol/staker split.
6. Listing bond — factory listingBond set to LISTING_BOND_SEAT (default 100_000e18).

#What it deliberately does not do

• No LP mint. If SEAT_LP_USDG is set, the script logs the intent to seed a $SEAT/USDG pool at the cited NPM (0x7399…E0D3) — the actual position mint stays a manual operator step, then the NFT is locked via LpLocker.
• No router changes. Execution posture is unchanged by the TGE.

#Configuration

# everything from the mainnet deploy, plus:
CONFIRM_SEAT_TGE=I_UNDERSTAND
SEAT_HOLDER=<token-recipient>
LISTING_BOND_SEAT=100000000000000000000000   # 100k * 1e18
LEADER_2=<second-leader>                      # optional
LEADER_3=<third-leader>                       # optional
SEAT_LP_USDG=<intended-lp-usdg-amount>        # optional, log-only

make deploy-phase2

#Post-TGE checklist

1. make write-addresses, commit.
2. Distribute $SEAT per the allocation — the buckets are post-TGE transfers from SEAT_HOLDER, not mints.
3. Mint the LP position manually, then lock the NFT in LpLocker for ≥ 365 days.
4. Verify stakerRecipient on every vault and a nonzero listingBond on the factory.
