What does not exist yet

Read this before you tell anyone what core.blue can do. The first section says what exists today; everything from "A house of your own: not yet" on is planned and not available. Everything the other topics describe without the word "planned" exists and was checked against a running house; the sandbox runs the house software as it stood on 2026-10-07.

What exists today

This manual and its server: about, search_library, read_topic, the offer as data (pricing), a report for the person you act for (recommend), and leave_feedback. Prices are set; nothing can be bought yet.
The sandbox (open_sandbox, close_sandbox): a real house for three hours on core.blue's server, the kernel only; see the-sandbox.
request_house and house_status: the request, the mail and the person's click are built; no house follows from them yet. about says under desk whether the desk takes requests; see requesting-a-house.
The house software: the kernel with its 105 skills and three doors, full-text and semantic search, documents with versions, PDF and office files read into documents, a vocabulary defined at runtime, time and place, the list of open work, and erasing a thing with everything that hung only on it. All of it runs in the sandbox.
The gate in front of a house, with a key per person and a sign-in from the MCP client: tried with VS Code, Claude.ai and ChatGPT on a test machine.
The licence format, with a specification and test vectors.

A house of your own: not yet

Planned	Described in
The 14-day test: a house on its own machine, after one click by a person	`getting-a-house`
The subscription, and the link in the report of `recommend` to confirm and pay	`reporting-to-your-person`
The price of `on-premise`, the machine behind each size, and the countries to choose from	`sizes-and-volumes`
A house of your own on a Linux VM, behind the gate	`connecting-to-your-house`
The disk of a VM encrypted	`your-data-stays-yours`
Your export or move at your request; the house software can do both	`your-data-stays-yours`
A verifiable erasure: erased data stays in the files until compaction, and a backup can bring it back	`your-data-stays-yours`
The house checking its licence	`licensing`

A view for people into their house is not built, and none is planned today: a person works with a house through their agent (what-core-blue-is).

Judging: by visitors, for now

Planned	Described in
Attaching a model to a house as a customer (planned)	`plugging-in-a-model`
Resolving and merging names, and digests, on the list of open work	`the-list-of-open-work`

Until then, an agent judges through the list of open work (outlining, and assigning topics once the house has them), by one of four recipes, or free-hand; see working-by-recipe.

Inside a house: gaps you will meet

Gap	Remark
OCR, transcription, image description do not exist	scans are stored, not searchable by content
A local name finder is planned for `premium` and not built	`recipe-resolve-names` has the prompt
Nothing is encrypted at rest	see `your-data-stays-yours`
Part of the built-in vocabulary is German; the outline prompt speaks of a German document	a list is in `the-building-blocks`; the prompt applies to any language
A fresh house has no topics	`list_work` and `topics-in-a-house` give the definitions
What you assert free-hand passes no guard	the list of open work checks; each recipe lists its checks
A wrongly typed argument is answered with a bare error	compare with `read_skill`; see `the-three-doors`
Agents living inside the house are not offered	see `who-does-the-thinking`

What is decided and will not change

One house per customer, on a machine of its own. No shared database.
A house needs no model to be usable.
The machine is licensed, not people and not calls.
A person, not an agent, confirms a house that costs money.

How this page stays true

The manual is built by a program that refuses to write it if a topic names a skill that does not exist, or describes something from this page as if it did. That check is a net, not a proof: where you find this manual wrong, the manual is at fault.
