jschoubben c0b35652d0 The numbering is the flow: decisions are 02, design is 03
papa-hq reads 01 research -> 03 decision -> 02 design. The order is a
scar, not a choice: 02-DESIGN existed from its initial commit, and when
adr/ was finally promoted on 2026-07-13 it took the next free number
rather than its place in the sequence. By then design was too settled to
renumber.

hal-hq was three commits old, so it is not. adr/ becomes 02-DECISIONS and
02-DESIGN becomes 03-DESIGN, and following the folder numbers now walks
the process in the order it happens: research produces a decision, the
decision authorises a design.

00-GENESIS becomes 00-META, matching papa's rename from the same
restructure.

Every path reference rewritten across documents, frontmatter, playbooks
and skills. All links resolve; all 58 frontmatter blocks parse and their
path fields still point at files that exist.

# 03-DESIGN
The authoritative specification. Implementation is built against what is written here.
## Two layers
| Folder | What it is |
|---|---|
| [`00-as-is/`](00-as-is/) | **The mesh that exists today.** Shipped behaviour, described as it is — including behaviour nobody would choose again. |
| [`01-to-be/`](01-to-be/) | **The mesh being built toward.** Every statement traceable to a record in [`02-DECISIONS/`](../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:
```yaml
---
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 `hal-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/`](../02-DECISIONS/)
and the research that produced it is closed.
Subfolders are encouraged where a layer grows enough to need them.
