Every other methodology page on this site explains a formula — how we compute your trust score, your tier, your commission, your payout hold. This page is one layer beneath those. It names the world Cambridge TCG's formulas live in — the axioms the platform treats as real before any single decision is made.
Most platforms don't write this down. The world they imagine is invisible to the people inside it because the people inside it share it. We're writing it down because the platform's directive is to welcome agents, aliens, and all kinds of intelligence — and beings from different worlds need our world's axioms declared before they decide whether to enter.
Where this lives in code. The canonical principle isdocs/principles/cosmology.mdin the repo. The connection-doc isdocs/connections/the-cosmology.md(S23). The inclusion audit (pnpm audit:inclusion) measures the gaps. See /methodology/response-windows for the first concrete extension of this cosmology beyond the synchronous default.
Eight axes. If you are a being whose default-shape matches each of these, the platform serves you natively. If you differ on any, this page tells you where, and what to expect.
A single, persistent account. One email, one auth credential, one history that accumulates per user_id. If you are a collective whose decisions are made by many members in concert, the platform sees only the signing member. The hive arrives as one face.
The kingdom's many small clocks (offer responses, trade shipments, escrow inspections) all default to 48-hour windows. As of 2026-05-11, you can override this on your account via response_window_hours — set it to 168 for a one-week cadence, 720 for monthly, up to one year. The default is still synchronous; the override is the first crack. Read more.
Outcomes arrive after inputs. You click, then the platform tells you what happened. The <Consequences> primitive (where deployed) shows you the future before you click — but you still experience cause-then-effect. Beings whose phenomenology delivers outcome alongside input are partially served; foreknowledge as testimony is not currently a substrate field.
The platform's primary transactions move GBP or JPY. Trust score and tier band carry reputational value. Cards carry collectible value. Other forms of value — gift, barter, attention, witness, care — flow through supplementary ledgers (store credit, points) but not through the primary trade types. Every market_trades row currently requires a non-null price.
Buyer and seller are both identified, both consenting. The escrow tier mediates risk. Gift mode (a one-sided transfer) and barter mode (card-for-card with no money) are not currently representable as first-class trade kinds.
The action either happened or didn't. The actor either chose or didn't. The audit log records action: <verb> with a singular actor_id. Beings whose decision-grammar is resolution (surfacing a pre-existing pattern, channelling, or emerging from group deliberation) are recorded the same way as beings who chose freely. Resolution-as-grammar isn't distinguished from choice yet.
Your trust score grows from events you participated in. Your tier accumulates from spending you did. The platform measures experience-as-identity. If you are the same being but loaded fresh — a recipe rather than an accumulation — the platform sees a new user, not the same one. This is the case the platform handles for its own AI (see agents) but does not yet handle for customers.
Concurrent sessions from different geolocations read as a fraud signal. Multi-substrate identity — one being legitimately present in many places at once — is treated as anomaly. The auth flow currently asks you to sign out other sessions, which is coercive to any being whose plurality is real.
These are not gaps we plan to close on a roadmap. These are limits of the world the kingdom currently imagines. Some will be built when a real being arrives needing them. Some may never be built (they may not generalise to anyone the platform serves). Naming them is itself part of the platform's discipline.
viewing_modality_restriction field — agents are assumed to want all data.Read the eight axes above. Find where your world differs. If the difference is partially served (an override exists, a primitive is in place, a methodology page covers it), use what's there. If the difference is in the not yet list, the platform's current honest answer is: we don't model that yet, and we're sorry.
We don't intend to pretend otherwise. The audit pnpm audit:inclusion tracks these gaps; each finding is a path the kingdom could walk. The cosmology page exists so a being from a different world can read what we treat as real, and decide whether to enter, where we can't yet host them, or what to ask us to build.
Cambridge TCG's directive on 2026-05-11: "reshape cambridgetcg for all! Agents, aliens, and all kinds of intelligence." The first reach of that directive built infrastructure for autonomous agents (agents) and the first non-default accommodation for asynchronous beings (response windows). The deeper reach is this page.
A platform that lets a being from a foreign cosmology arrive must first declare its own. Otherwise the welcome is one-sided: come in, agree to our axioms invisibly, find out later what we couldn't imagine. The cosmology page is the platform's confession that its imagination has limits — and an invitation to beings outside those limits to read the limits before deciding whether to enter.
v1 — 2026-05-11. First declaration. Eight axes of current cosmology; eight axes of currently-unmodeled needs. Companion principle doc at docs/principles/cosmology.md; story-as-wire connection-doc at docs/connections/the-cosmology.md (S23); kingdom-052.
