The gap

Prior art assumes an architecture in which asserting against a counterparty and being held to account are governed by separate accounts. The act of writing into another agent's governance state — flagging conduct, lodging an evaluation — is treated as free, or is throttled only from outside the agent: by a rate limit on a channel, or by a stake denominated in reputation or held value. Under that assumption the quantity restraining an agent from asserting bears no fixed relation to the quantity governing what the agent may itself do. The two are measured in different units, and nothing converts one into the other.

The asymmetry is structural. An agent can spend freely in the direction of assertion because the meter for assertion, where one exists at all, is a foreign currency to the meter for action. There is no single held quantity that both restrains an agent from refusing an execution and restrains it from asserting against others, so the two directions in which an agent writes into governance state fall to separate ledgers — or, in the case of assertion, to no ledger the agent itself carries.

The invention

Assertion-Cost Symmetry prices assertion from the same quantity that gates the agent's own actions. When a semantic agent issues a conduct evaluation artifact against a counterparty, an assertion-cost counter increments and the authorization budget — the quantity gating dispatch of the agent's actions, in units identical to those gating dispatch — is decremented by a policy-declared amount. The counter increments once per origin-equivalence class of receiving parties within a metering window, so an agent asserting against many distinct counterparties pays per distinct class rather than per artifact. Each issued artifact carries an attestation binding the accumulator state to a specific epoch of the agent's hash chain. Two properties follow.

First, the construction mirrors the refusal-cost mechanism the agent bears in the role of evaluated party. An agent that refuses an execution pays a metered cost for the refusal; an agent that asserts against a counterparty pays a metered cost for the assertion — each cost applied without any adjudication of the merit of the refusal or of the assertion, and both drawn from one authorization budget held by the party taking the action. Second, the decrement is denominated in the units that gate the agent's own execution: no exchange rate, no conversion between an assertion-denominated quantity and an execution-denominated one, and no budget denominated in channel access, rating weight, or staked value. An artifact resolved by its recipient to any determination — accepted, rejected, not-determinable, or not-applicable — bears one and the same decrement.

The inventive step

The departure from prior art is where the meter lives and what it is denominated in. Assertion is not throttled from outside by a channel or a stake; it is priced against the agent's own authorization budget, the same quantity that decides whether the agent may execute. Spending the budget down to assert therefore spends down the capacity to act, and there is nothing to convert, arbitrage, or re-denominate between the two directions. When the budget falls to a declared floor, the authorization gate is written to the withheld state for an enumerated set of action classes and the agent enters a non-executing cognitive mode with respect to them — while its capacity to issue artifacts is left untouched. The faculty withheld is that of executing actions, not that of asserting.

Metering runs on the successor epochs of the agent's dynamic agent hash chain, not on a clock. A successor epoch is not computable in advance by the issuing agent and not computable at all by any other party, so the metering interval cannot be advanced by manipulating a host clock. Because an attestation binds an accumulator state to one epoch, an agent that issues many artifacts attesting a common state stamps them with a common epoch identifier — and a recipient holding a prior artifact bearing that identifier detects the repetition from its own record of the counterparty. Verification stands as a precondition to admission: a recipient confirms the attested epoch is a valid successor of one it previously recorded and that the accumulator state has not gone backward, and an artifact whose attestation is absent or fails to verify moves no value and produces no determination. The check turns on no party beyond the two to the exchange.

Alone, and in composition

On its own, the mechanism is a self-contained price on assertion. An agent that issues conduct evaluation artifacts pays per distinct class of recipient out of one budget; that budget is replenished only by exposure to counterparties whose artifacts it has not yet been implicated by — never by elapsed time, never by its own issuance, and never above a declared ceiling — and the replenishment amount is set below the decrement, so an agent cannot finance a volume of assertion out of the receipts its own assertions provoke. The illustration in the disclosure is concrete: at a decrement of one unit per increment against a budget of forty units, an agent asserting against sixty counterparties in sixty distinct classes within one window exhausts the budget at the fortieth increment, and the remaining issuances carry no valid attestation.

In composition, the symmetry closes the loop with the rest of the governance object. The authorization budget this mechanism decrements on assertion is the same budget the acknowledgment mechanism decrements and the refusal mechanism meters against — one quantity governing the agent whether it asserts or is asserted against. Origin-equivalence classes, computed once for the agent, serve here to price recipients and elsewhere to bound who may assert against it; the dynamic agent hash chain that clocks this counter is the same chain the surrounding layers meter on. Assertion-Cost Symmetry is the direction in which the agent writes outward, and the layers around it govern the direction in which it is written to — both priced from the same held quantity.
