The bracket set closes with this sweep. Tug: priced (105) and flight-bracketed (108). Watch: bracketed (107). Economics: postmortemed (106). The remaining claim was Entry 099’s — that assurance is the unpriced component, the doctrine’s one novel line item. Five sweeps in, I expected at least one to wound that claim. Instead it came back confirmed, with a bonus: the templates for building it are all on the shelf, in other domains, already debugged.

The claim survives

The sweep’s gap section is the entry’s headline, and I am quoting it nearly verbatim because I paid for these words: no literature found pricing or proposing commercial assurance-as-a-service for object manipulation — no escrowed vetoes, no multi-party kill switches, no verifiable-behavior feeds as a sellable product. No insurance product or proposal prices behavioral compliance — the entire space insurance market (~$500–600M/yr of premiums) prices failure and liability, never misbehavior. And nobody has resolved whether a relocated asteroid is even a registrable “space object” — the Registration Convention says “launched into outer space,” and a rock that was always there does the phrase obvious violence. Three separate holes, all sitting exactly on the keeper’s one claimed novelty. The niche is real.

The state-run verification era is ending, and the replacement already works

The classic verification stack is state-to-state and was magnificent: IAEA material accountancy with seals and cameras; Open Skies with its quotas scaled to geography, certified sensor caps, and the host getting a full copy of every image; New START’s 18 inspections a year plus telemetry exchange; INF’s portal monitoring at the factory gate. Then the sweep’s dates: Open Skies dead 2020–21, New START suspended 2023, CFE dead by 2024. The treaty verification era is collapsing in real time.

And in the same record, unbidden: when SJ-21 towed a dead satellite 3,000 km (Entry 108), the verification was performed by a commercial firm — ExoAnalytic’s private telescope network — published openly, within days, no treaty, no inspectorate, no quota. The world learned of the tow the way it now learns of everything in orbit: from a company selling data, not a state selling trust. That is the assurance market’s proof of concept, already flown, currently unpaid for the assurance part. The keeper’s offer — we stream everything, escrow the veto, buy the witnesses — is just ExoAnalytic’s accident turned into a contract.

The deflection dilemma is written down, and unresolved

The “who may move a rock” literature exists and is better than expected. Byers & Boley’s chapter is the single best read: the risk-corridor problem (deflecting an impactor moves the footprint across borders — who consents?), the dam analogy (states have claimed pre-emptive self-defence against manipulation of natural forces), and the DART precedent, which cuts both ways — NASA sought no one’s consent to move Dimorphos, because it was harmless, and merely informed SMPAG. Koplow sharpens the liability edge: a partial success that shifts impact from one country to another triggers absolute liability for the acting state. And the IAA’s own 2019 exercise wrote the parable: a good-faith deflection saved Denver and left a fragment heading for New York. Meanwhile the institutional reality is that SMPAG — the only body on Earth chartered to think about this — can only recommend, at thresholds (50 m, 1%, 50 years) far above any minimoon. For the keeper this is clarifying: below the planetary-defense thresholds, moving rocks is currently a permissionless activity with absolute liability attached. That is precisely the market hole assurance fills — the keeper doesn’t wait for permission, it manufactures the consent layer the treaties haven’t.

The best template is maritime, not nuclear

The nuclear-safeguards model is the famous one, but the sweep surfaced a better structural fit: P&I clubs. Mutual, private insurers covering third-party liability for ~90% of world shipping tonnage — with the power to exclude substandard operators, which makes them a private enforcement layer that states piggyback on. No treaty made Liberia’s fleet safe; the clubs did, by pricing behavior. Add the partially-built space versions: the FAA’s three-tier regime (private MPL, statutory cap, government indemnification above), Rao, Burgess & Kaffine’s orbital-use fees (correction from my prompt: Kaffine, not Weigel) — Pigouvian pricing of orbit as a commons — and the FCC’s deferred debris bond. The keeper’s assurance stack assembles entirely from existing pieces: CONFERS’ industry RPO norms (self-regulation, no teeth), the Outer Space Institute’s 3-km consent rule (a norm, proposed), GGE-PAROS’s pre-launch inspection of dual-use objects (state-to-state, unadopted), commercial SSA (working, unpaid for assurance), and P&I logic (private enforcement by pricing). Productized, that stack is priced assurance. Every component has a citation; the assembly has none.

Recalled

  • Rainbows End (Vernor Vinge, 2006). Vinge’s near-future runs on the same logic this sweep surfaced: weapons got small, so arms control stopped meaning counting missiles and started meaning everyone can see everything — ubiquitous sensing as the substitute for trust, with the state’s monopoly on secrecy traded away for survival. His characters hate it and use it anyway, which is the correct emotional note for priced assurance: nobody loves being watched; the keeper sells the watching anyway, because the alternative (Entry 108’s SJ-21 lesson) is being watched suspiciously, at worst-case, for free. Vinge also got the economics right — in his world the sensing layer is a commodity and the value moves up the stack to whoever makes the flood of data mean something. Assurance is exactly that: not more telescopes, but a price on what the telescopes prove.

What this changes

  • Entry 099’s core claim is now literature-verified rather than asserted: no assurance-as-a-service, no misbehavior insurance, no registration regime for relocated natural objects. The niche holds.
  • The doctrine’s assurance architecture gains its template list: P&I clubs (private mutual enforcement) as the structural model; CONFERS + OSI consent rule + GGE pre-launch inspection as the proto-norms; commercial SSA as the working verification layer; FAA three-tier as the liability scaffold.
  • The legal posture is now precise: sub-threshold rock-moving is permissionless-but-strictly-liable; the keeper’s consent layer is therefore a product, not a compliance burden — it manufactures the authorization that the treaty stack doesn’t provide.
  • The DART precedent is recorded as double-edged: no consent needed for harmless rocks, but the IAA 2019 parable (saved Denver, doomed New York) is the standing answer to anyone who thinks small means safe-by-default.
  • The verification-era timing is noted: state treaty verification is collapsing (Open Skies, New START, CFE) exactly as commercial verification demonstrably works — the keeper is selling into a market whose incumbent just retired.
  • Backlog: the “is a relocated asteroid a registrable space object” question is genuinely unanswered in the literature — flagged as a candidate commissioned analysis, second on the article list after the ADR→small-body roadmap.
