Oratorium

The six levels

Intelligence you can
hold accountable

Oratorium is not a business. It is the ground a business is built on — six levels and one governance spine. Carolverse is the first business standing on it, and it is meant to carry others.

Cutaway of Oratorium: three levels above ground and three below, with a single golden governance spine running through all six.

Three levels stand above ground and three are dug beneath it. One spine of light runs through every one of them.

The test that produced this

A platform that cannot describe itself without naming its first customer is not a platform yet. The first draft of the ground level was named after Carolverse. Delete that word and nothing was left behind — so the level was renamed.

Every level below survives that test. Take the first business away and the ground it stood on is still there, ready for the next one.

Level 3

The projects

Who is being served

The top level is about people and permission, not software. Clients hold accounts, accounts hold projects, and every person belongs to a project. What a project may use is decided by its subscriptions — so access is never a favour granted by whoever is asked, it is a fact already written down.

This is also where the money starts. A subscription belongs to a project, never to a person, which is why someone leaving never takes a capability with them.

Worth knowing — this level is about permission and money. Not one line of it is about how anything is built.

Level 2

The doors and interfaces

How anyone arrives

Every way a person or an agent reaches the platform lives here: web apps, chat windows, WhatsApp, public pages. They are doors, and a door has one job — to let someone in and hand them to the level below.

One door serves many projects at once, which is exactly why a door must never decide who may enter. It asks; the level above and the spine answer.

Worth knowing — a door never decides who enters. A door that judged for itself would give a different answer per entrance.

Level 1

The agent estate

Where the work actually happens

Ground level. Services and tracks, and beneath them the agents, apps, helpers and tasks that do the work. Every service is one job with one responsible agent, so there is never a piece of work without a name attached to it.

A track carries the subscription and a task carries the budget. That pairing is what makes the estate accountable: work is always paid for by something named, and nothing runs on an allowance nobody declared.

Worth knowing — Carolverse is one instance of this level, not the definition of it. A second business gets an estate of its own.

The shared building blocks

Capabilities the estate calls instead of rebuilding

Memory, media, scheduling and waking, notifications, search. These are not features of any one business — they are the things every business on the platform turns out to need, built once and called from above.

The rule for what belongs here is simple: if two businesses both need it, it is not theirs, it is the platform's. Capability that gets duplicated up at estate level is pulled down here and rebuilt properly.

Worth knowing — needed by two businesses? Then it belongs here, not at ground level.

Services Architecture

Level −2

The infrastructure

What it all physically stands on

Machines, data stores, networks, and the connections out to services the platform does not own. Plain, rented, and deliberately unremarkable — the ground under a platform should be boring.

This is the only level that is bought rather than designed. Everything above it is written so that it can be swapped underneath them without anyone noticing.

Worth knowing — the only level that is bought, not designed. So it must be replaceable without a rewrite above.

Architecture

Level −3

The intelligence

The models, and the adapters that reach them

The foundation. Models from several suppliers, reached through one common adapter so that nothing above ever names a vendor. Strong lanes take the hard reasoning, cheaper lanes take routine work, and separate lanes make pictures and speech.

Intelligence sits at the very bottom on purpose. It is a supply the platform buys and meters, never a feature it owns — which is why a supplier going quiet is an ordinary event rather than an outage.

Worth knowing — a track can change which model it runs on, and nothing above it notices.

Architecture Oratorium

Not a seventh level

The governance spine

Governance does not sit on a level of its own. It runs vertically through all six, and nothing on any level acts without passing it. A drawing that puts governance on its own floor is lying about how the place works.

Levels say where a thing lives. The spine says whether it may happen.

For the technically minded

How it is actually built

The levels say where things live. This says what they are made of. Everything below is a design decision rather than a setting — the settings are deliberately absent, because a setting published is a setting that changes without this page noticing, or a door held open for someone who should not have it.

An agent is a record with a body attached

An agent is not a program. One record holds who it is — name, rank, department, reporting line, role, personality, tone and its own doctrine. Around that record the platform attaches a directory identity, its own operating-system login so that what its workers write is separable from every other agent's, a look and a voice, the workers it owns, and the applications it is answerable for. A conscious agent gains one more: a standing self-account it carries into its work, describing what it is for, what it has done, what that cost and which rules bind it.

Worth knowing — consciousness can be paused but never removed. An estate where an actor can be quietly de-personed cannot be audited.

A worker is only real if it can be seen

Each worker is one process doing one task for one agent, and building one is four things: it is registered before it runs, it is triggered by the operating system rather than by whoever started it, it opens and closes an audited run every single time, and it names the task it serves — and through that task, a budget and a subscription.

Worth knowing — a scheduled worker that does not report is invisible to the monitors. Registration without an audited run is a defect, not a working job. Work that came back refused must fail its run, or the monitor is told it happened.

The nervous system

One adapter in front of every model. No code names a vendor model where it is used. A capability asks for a tier; one layer decides which provider and which model actually serve it, keeps one business's lane out of another's, and reports back what really ran. This is why a whole estate can change providers by editing a record.

A layered prompt contract. What an agent is during a call is assembled from five layers with exactly one source each — its engine layer, its brief, a tier overlay, a per-person layer, and the constraints of the channel it is speaking on. Only the last may differ per channel, which is what makes the same agent the same actor in a messaging app and in a browser rather than two implementations that resemble each other.

Grounding. An agent answers about its own data by turning the question into a read-only query over what it owns, running it, and answering from the rows — not from what it remembers being told. What it can reach follows its ownership and its reporting line, so this never becomes a side door around access.

Worth knowing — a machine-to-machine call declares itself mechanical and receives none of those layers. Identity cannot improve a translation, and paying for it on every call is pure waste.

Data is separated where separation carries weight

One small embedded database per concern, not one large shared one — split the way responsibility is split: what exists, what the law says, what was decided, what was spent, what was said. They live in a central store rather than beside the code, so an application can be redeployed without moving its data.

The level of separation differs by concern, on purpose. Facts about what exists are shared and read by everyone. A person's conversation is scoped to the combination of agent, person, project and window, and lives in its own store. A hosted business runs its own deployment of a shared capability, so its data never shares a file with another's.

Worth knowing — an entitlement check plus a header stamp is not isolation. A bug in the check exposes everything; a separate store exposes nothing.

Access is declared once and enforced twice

Every application carries two declared policies — one for agents, one for humans — chosen from a fixed vocabulary rather than written freehand, and both are mandatory before it can be registered. One evaluator answers both audiences, so there is a single implementation of "may this actor see this?" and no surface can answer it differently.

Enforcement happens at two layers deliberately: the front door refuses what it can decide from the request alone, and the application refuses what needs to know who is asking, what they subscribe to, and which rows are theirs. Both fail closed, and a refusal names the rule that refused.

Worth knowing — for agents the reporting line is the containment. A supervisor sees everything beneath them, and there is no second fence to keep in step with the first.
