Fee Matrix — every split in one table

Every recurring payment split in Dark Matter, with its source, destination, and where it’s enforced. If it takes a fee anywhere in the protocol, it’s on this page.

On reactor deposits (`injectMass`)

#	Stream	Rate	Destination	Enforced by
1	Team fee	5%	`teamAddress`	Hardcoded split in `injectMass`
1a	└ Gas-sponsor skim	≤5% of chunk 1 (≤0.25% gross)	DarkMatterTreasury	`gasSponsorBps`, capped by `MAX_GAS_SPONSOR_BPS = 500`
2	Marketing fee	5%	`marketingAddress`	Hardcoded split in `injectMass`
3	Stock dividend	1%	StockDividendVault (daily pool)	`stockDividendBps = 100`, one-shot wired
4	Founder pool cut	1% (=10% of the 10% fee bucket)	FounderPass `receive()`	`POOL_FEE_SHARE_BPS = 1000`
5	VIP pool cut	1% (=10% of the 10% fee bucket)	EventHorizonPool weekly pots	`POOL_FEE_SHARE_BPS = 1000`
—	Radiation purchase fee	10% of bought radiation	Referral tree (5/3/2/1% + curve)	`devFee()` at buy time
—	DUST mint	0 ETH cost	Depositor (500 DUST/ETH)	`_earnStardust`

Total gross fee: 12% + skim (≤12.25%); ~88% of every deposit works for the depositor.
