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.

+**The primitives.** Four documents, in `.loom/published/`:
+
+- [The `.loom` directory](.loom/published/loom-directory.md) — everything lives
+  there, and a directory means a kind
+- [Sibling facets](.loom/published/sibling-facets.md) — `x.<facet>.md` beside
+  `x.md`, owned by whoever wrote the facet
+- [Recording decisions](.loom/published/recording-decisions.md) — what an entry
+  says, and why it is never revised
+- [Publication](.loom/published/publication.md) — what `.loom/published/` means
+
+**Nothing here says what to *do*.** *`loom/annotating`, `loom/cart` and
+`loom/externals` are built on these and are where the practices live.*
+
+**Most repositories will never read this.** *Its audience is people building
+conventions, not people using them — and it is a good sign that a primitive is
+one nobody needs.*
+
+**Publishers are the exception**, because publication is defined here, and the
+people whose choices land on somebody else should have read the primitives.
