the four primitives

Depended on by the conventions built on this, and depending on none of them.

- the .loom directory — everything lives there, a directory means a kind, a
  stream is a file. Fixes .loom/ and deliberately not which kinds exist.
- sibling facets — x.<facet>.md beside x.md, owned by whoever wrote the facet,
  never by whoever wrote x.md. Plus the three choices a convention must make.
- recording decisions — what an entry says, why it is never revised, and why it
  has no status field.
- publication — the act, the contract, and that what is published is a document.

Also carries the event log and declines from cart `almanac`, which ran 2026-09-04
to 2026-09-07 and produced seventy-eight entries. Read it forwards; entry 69 is
where it changes its own mind and brackets most of what came before.

The git history here starts now. The event log is the history that matters.

+# Publication
+
+**What a repository has handed over for others to depend on lives in
+`.loom/published/`.**
+
+> **Publishing is a change of kind, not a change of status.** *An unpublished
+> document is an implementation detail you may rename at will. **A published one
+> is a contract.***
+
+**So publication is an act somebody performs** — a file moves in — **and the move
+is a diff that shows up in review.** *A flag in frontmatter is a line nobody
+notices; this is the moment a thing becomes somebody else's problem, and it
+should be unmissable.*
+
+**`ls .loom/published/` is *what have we committed to?*** — and it is the question
+to ask before changing anything.
+
+## What is published is a document
+
+**Prose, in whatever form its readers need.** *If a repository organises its
+thinking some other way internally, that is its own business:* **a consumer
+cannot tell whether it did, and must not need to.**
+
+> **What is not exported is not hidden.** *The rest of the repository is there to
+> read. It is simply not what you depend on.*
+
+## There is no directory for what is unpublished
+
+**Everything else is simply elsewhere in the repository.** *Naming the complement
+invents a category — and a directory called `internal/` would look like a
+security boundary and not be one.*
