+# kb/ - Authoring Conventions of This Instance
+
+The decisions [kb/CONTRACT.md](CONTRACT.md) deliberately does not make. The contract holds what
+the code enforces and is identical in every instance; this file holds what *this* instance
+chooses, and no other instance has to agree with a word of it.
+
+**It binds all the same.** Everything below applies to every page under `kb/`, exactly as the
+contract does. The difference is ownership, not authority: a rule here is changed by editing
+this file, a rule there by changing the stack.
+
+Ready-made answers to every section below - including a complete German profile - are in
+[instructions/kb-profiles.md](../instructions/kb-profiles.md). That catalogue is a palette, not
+an enum: adopt an entry, adapt it, or write your own. What is written *here* is what holds.
+
+The frontmatter above is the one machine-read part. `sections:` names the three headings
+`wikitool xref` and `wikitool cite` write into. Set them before the first page is written:
+afterwards, changing one is a corpus migration rather than an edit.
+
+## Language
+
+Pages are written in **{language}**. This binds `kb/` and the authoring surface that shapes it -
+the page type-specs `types/entity.md`, `types/concept.md`, `types/source.md` and
+`types/comparison.md`, whose `## Template` blocks are the body skeleton every new page starts
+from. `raw/` is untouched ([raw/CONTRACT.md](../raw/CONTRACT.md)), and the control plane stays
+English: `AGENTS.md`, the stage contracts, this file, `instructions/`, and the type-specs for
+non-page artifacts.
+
+Which line is prose and which is an identifier - and therefore what is translated at all - is
+the contract's rule, not this file's: see
+[kb/CONTRACT.md § Language and identifiers](CONTRACT.md#language-and-identifiers).
+
+{Which established foreign-language technical terms stay untranslated inside this instance's
+prose, and where the vocabulary for that is looked up. Delete this paragraph if the KB language
+is the one those terms are already in.}
+
+### Section headings
+
+The canonical names are the frontmatter's. Any name this instance previously wrote stays
+recognized through `section_aliases:`, which is what lets a corpus be translated page by page.
+Renaming such a heading is the translation pass's job, never a side effect of another command.
+Any *other* heading an author adds is ordinary prose.
+
+## Naming
+
+- {Title form - words and spaces, or kebab-case, or the subject's own spelling.}
+- {Singular or plural for entities.}
+- {How a comparison page's title reads.}
+- {The ADR prefix, if this instance files decisions as pages.}
+- {What to name a thing: projects, systems, tools, technologies, people.}
+
+The one naming fact that is *not* a choice, and therefore lives in the contract: the filename
+stem is the page title, and `[[wikilinks]]` must match it exactly.
+
+## Tone
+
+{The register pages are written in, in one line.}
+
+- {Words and constructions this instance refuses, with examples in the KB language.}
+
+Good: {one sentence that is what this instance wants.}
+
+Bad: {the same sentence written the way it must not be.}
+
+## Relationship labels
+
+`tools/wikitool xref add --rel-a/--rel-b` takes a free-text label. Listing the ones this
+instance uses is what keeps a graph typed rather than a wiki full of "related to":
+
+{the label vocabulary, in the KB language}
+
+No code matches on these, so an old label on an untranslated page is stale wording, not a
+broken reference.
+
+## Confidence rubric
+
+`confidence_base` is set by hand and `confidence` is derived from it - that mechanism is the
+contract's. What the number *means* is this instance's:
+
+{the base score, what raises it, and by how much}
+
+{How to hedge in prose at a low score, in the KB language.}
+
+## Keeping this file honest
+
+Change it when a convention actually changes, and treat a change to `sections:` as a corpus
+migration rather than an edit. `wikitool doctor` FAILs on a missing or unfilled file, and
+`wikitool docs verify` refuses a `sections:` block that does not name all three slots.
