Receipt-gated minting, tax, and thickness

Receipt-gated minting IMPLEMENTED

A node earns minted output only by relaying work between two independent peers — relaying is a three-party act (originator, carrier, receiver). The self-reported contribution path was removed (Phase 6). With fewer than three independent peers, the mint correctly produces nothing, because there is no third party whose traffic can be carried.

Georgist resource accounting IMPLEMENTED

The economic engine applies a Georgist frame: resources are priced by use rather than hoarded, with a tax-and-redistribution cycle per epoch. Amounts are integer basis points — no floating point on the vouch path — so independent nodes reach byte-identical results.

Thickness — the provenance graph IMPLEMENTED

Thickness is the influence metric, and it is derived, not stored: each node computes it at read time from stored inputs (basis points). A chained clawback unwinds the downstream effect when a source contribution is revoked, so a liquidated source cannot leave ghost influence behind. Nonces are strictly sequential; gaps are filled by a fetch protocol.
