jschoubben c3ec1487c7 What a module may borrow, what it may need, and what one assignment gets
Three additions, all written by trying to write a real database module
and finding out what could not be said.

A module may mirror an image it did not write. Naming an upstream
reference directly needs every machine to reach a public registry and
pins to a tag somebody else can move.

A module may need a secret of its own — a superuser password is not FOR
anybody, so the mechanism that hands credentials to consumers cannot
express it. Per node, so three machines have three passwords.

And the provisioner watches, which is what lets it be a module rather
than a binary somebody places. It polls rather than watching the
filesystem, because the host writes atomically and a watch on a replaced
path silently stops working.

One assignment now gets a working database provider: two directories, two
pinned containers, a sealed password and the grants manifest.

03-DESIGN

The authoritative specification. Implementation is built against what is written here.

Two layers

Folder What it is
00-as-is/ The mesh that exists today. Shipped behaviour, described as it is — including behaviour nobody would choose again.
01-to-be/ The mesh being built toward. Every statement traceable to a record in 02-DECISIONS/.

They are never mixed. A statement about the future does not belong in an as-is document, and an as-is document is never edited to describe an intention.

When a to-be design ships, it does not move. Its as-is counterpart is written or updated, the to-be document's status becomes implemented, and both stand — one describing what runs, the other recording what was intended. Deleting the intention loses the reasoning, which is the expensive half.

Frontmatter

Every design document (not the READMEs) carries:

---
layer: as-is | to-be
status: designed | in-progress | implemented | abandoned
code: []                 # owning code repo(s), from 00-META/repos.md
updated: YYYY-MM-DD      # date of the last status change, not of text edits
decisions: []            # 02-DECISIONS/ records this document rests on
---

For an as-is document, status: implemented is the normal state — it describes something that runs — and code: names where that implementation lives.

Status changes when implementation state changes, never because design text was edited. An implemented claim must be defensible from the owning repository's main branch, not from intent. If it cannot be checked, it is in-progress.

Cross-cutting views are generated from this frontmatter by the hq-status skill and never written to disk.

What belongs here

Functional analysis, architectural description, and specification — prose and diagrams only, no code. A manifest field may be named; a manifest may not be pasted. A document enters the to-be layer only after the decision behind it is recorded in 02-DECISIONS/ and the research that produced it is closed.

Subfolders are encouraged where a layer grows enough to need them.
