jschoubben 476cda417d ADR 0135 supersedes 0133: a module version prepares its state before it runs
Two faults in 0133, both caught on review. It put the declaration on a container — one resource kind
the host applies — so every author would restate the machine's arrangement and a module's own
lifecycle would be tied to how its artifact happens to run. A module declares entrypoints for its
tools and its provisioner; preparing its state is the same vocabulary and nothing about a runtime.

And it derived the scope from the machine, which the facts already answer: a consumer is a module on
a machine (issue 022, migration 0015), so what the mesh provisions is per consumer. A module on three
machines has three databases, there is no shared state to race over, and the lock obligation 0133
invented was for a situation the mesh does not produce. The level question HAL answered with stages
dissolves — the scope of preparation is the scope of the state, and the mesh knows it.

0133 keeps its reasoning and gains a pointer; design 32 and issue 133 name the live record.

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.
