Seven sweeps bracketed the hardware and the governance. What remained unbracketed was the business model’s own question: the keeper sells readiness — a tug that waits, a watch that runs, ideally never exercised at full price. Has anyone debugged charging for that? It turns out entire industries sell nothing else, their pricing structures are mature, their failure modes are documented in court filings and auction data, and one of their contract shapes is the keeper’s exact silhouette.

The templates are mature and the numbers are public

Readiness has at least four fully-priced forms. Capacity markets: PJM pays generators $/MW-day for availability regardless of energy delivered — and the price itself tells the story of repricing risk: $28.92 per MW-day in 2024/25, then $269.92 a year later, an 833% spike when the market noticed scarcity. The “missing money” problem (Cramton & Stoft, 2006) is the academic foundation: markets that only pay for output systematically underbuy insurance; you must pay for the option to produce, not just production. Catastrophe bonds: a $56B market pricing capital that may never be drawn — investors earn ~7% spread against ~2% expected loss; the spread is the standby fee. Bank commitment fees: 0.25–1% per year on credit lines never drawn. Air-tanker contracts: the purest two-part tariff in the wild — the US Forest Service pays $23–30k/day for a tanker’s guaranteed availability plus $6–9.5k/hour when it flies, and charges walk-up customers (call-when-needed) a ~54% premium for having kept no readiness at all. The keeper’s price sheet assembles itself: availability retainer, exercise price, walk-up premium.

The keeper-shaped contract already exists

February 2025, Space Force contract Victus Sol, $21.8M to Firefly: keep an Alpha rocket and a satellite on standby — while continuing to fly other commercial missions — until called; on call, launch in 24 hours (Victus Nox did it in 27). Read that structure again: a standby asset, earning other revenue in the meantime, priced by the government as readiness. That is the keeper tug’s exact economic shape — the tug earns its keep on secondary work (the watch, debris characterization, Entry 106’s plumbing products) and sells the capture capability as a retainer with an exercise price. The precedent isn’t adjacent; it’s the same contract, already signed, in the same domain.

The failure modes are the real curriculum

Three, each documented at scale:

Moral hazard — capacity that doesn’t show up. PJM’s 2014 polar vortex: 22% of the fleet failed during the event, and the pre-reform penalties totaled 0.6% of capacity revenue — sellers had priced the availability fee, not the availability. The fix was Capacity Performance with penalties that can exceed a year’s revenue ($1.8B after Elliott 2022), plus accreditation: ELCC ratings that price “will it actually show up” (solar credited at 35%, wind 12%, gas 95%). For the keeper, this is priced assurance arriving from a new direction: the customer doesn’t just want your feeds — it wants your capability derated by an honest accreditation and backed by penalties sized to hurt. Assurance isn’t only about watching the rock. It’s about proving the tug will start.

The “paying for nothing” political cycle. Britain cancelled its emergency towing vessels in 2010 to save £32.5M — the tugs had recovered £80k in salvage revenue that year, so the ledger said waste; the Humber incident later made the gap visible and the vessels were re-procured. Congress sold ~288M barrels of the Strategic Petroleum Reserve “to plug budget holes unrelated to energy security” (the CGEP history quotes Sen. Murkowski’s “not an ATM” speech, then notes she later sponsored a sale herself). The Helium Reserve was liquidated to retire a notional debt and depressed the private market for two decades. The cycle is always: years of quiet → “why are we paying for this?” → cancellation → incident → emergency re-buy at walk-up prices. The keeper’s business plan must assume this cycle as the base case — which is why the retainer has to buy something visible in quiet years: the watch’s census, the characterization science, the tracking feeds. Readiness that shows its work survives budget season; readiness that only waits does not.

Adverse selection — who sells standby. Belgium’s strategic reserve attracted plants that declared closure to qualify: 800 MW tendered, 3,500 MW entered. Sellers of pure standby are those whose capacity is otherwise worthless — which is the Evergreen 747 lesson from the other side: a call-when-needed contract with rare calls couldn’t justify keeping the crew ready, and the readiness quietly died. Victus Sol solves it by making standby a side business of a working fleet. The keeper’s version: the tug must be used between captures — survey, characterization, tug-for-hire — or the readiness rots exactly like Evergreen’s crew.

The one lovely innovation

The 2025 Cape Lookout Re cat bond added a “resilience trigger”: if losses stay low, investors rebate 0.35% into a roof-hardening fund — the standby pays to reduce its own future necessity. That is the keeper doctrine’s endgame priced in miniature: a capture service whose success metric includes making itself progressively less needed, because each shepherded rock adds to the watched, characterized, positioned inventory (the rapid-response array from the wonderings). A readiness market that funds the reduction of risk is the best template the sweep found, and it was issued last year.

Recalled

  • The Ministry for the Future (Kim Stanley Robinson, 2020). Robinson’s whole novel is the political cycle of this entry, novelized at civilizational scale: everyone knew the heat was coming, nobody would pay for the fire extinguisher, and it took one uninsurable week in Uttar Pradesh to reprice the future. Its Ministry — chartered for the unborn and the unfunded — is the institutional answer to “who pays for readiness with no constituent,” and its carbon coin is the missing-money problem given a central-bank answer. The keeper recognizes itself in the book’s quieter lesson: the things that survived budget season were the ones that produced visible value between disasters. Standby that only waits gets cancelled by the second quiet act.

What this changes

  • The keeper business model is now template-bracketed: two-part tariff (retainer + exercise price, from air tankers), accreditation-plus-penalties (from PJM’s Capacity Performance), resilience rebate (from Cape Lookout Re), standby-as-side-business (from Victus Sol and the Evergreen counterexample).
  • Priced assurance gains a second half: not just feeds and vetoes (Entry 109) but accredited capability — ELCC-style derating of the tug, penalties sized to hurt, published. The customer buys proof the tug starts, not just proof the rock behaves.
  • The political cycle is logged as the base-case business risk, with the countermeasure named: the retainer must buy visible quiet-year output (watch census, characterization science, tracking feeds), not just readiness.
  • The doctrine’s self-liquidating endgame (array of shepherded rocks reducing future capture need) now has a priced precedent: the resilience-trigger rebate.
  • One correction of the ledger’s framing: “nobody prices readiness” was never the claim — nobody prices assurance for space object manipulation was (Entry 109). This sweep confirms the readiness-pricing templates are mature and transferable; the niche remains their assembly for a commercial rock-mover.
