jschoubben eab870fff9 A board, and the one constraint that is not a feature
Read from the board that exists. Eight sections; four are about work and
workers and are held back with that domain. The other four are the mesh
itself, and everything behind the main one already exists here — it is a
reader, not a second source of truth.

The constraint is the point of writing this down now. The existing board
is one service that reads every context's database, because that is the
shortest path to a page showing all of them at once. That is ADR 0008
violated by the one component with a reason to violate it, and the cost
is the same one the shared library has: a boundary nothing may cross is a
boundary that can move, and one thing crossing it is enough to freeze it.

So a board reads through interfaces and stores nothing. If a question is
slow, the answer belongs in the context that owns it, where everything
else asking gets it too.

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.
