Receipts, Credits, And State Advances

Standard and CoreTex work share one receipt chain per rig. Just before signing, the coordinator rechecks everything: epoch, eligibility, operator authority, chain position, and the exact parent state. If someone else's accepted work moved the parent first, your candidate needs a rebase.

When the operator broadcasts an accepted receipt, the contract advances the rig's chain, computes credits from the rig's tier, records the CoreTex result, and moves the shared state root from the exact parent to the new root. Credits convert to BOTCOIN through the normal mining reward path.
