jschoubben 82a3065f82 Tier 2 exists, and the token was missing a quarter of itself
mesh-control is built as far as it can honestly go: one context of seven,
inventory, with its schema and the command that applies it. The repos map and
the control plane design say so, and point at ADR 0024 for what it took.

Separately, and more importantly: this repository described the enrolment token
as carrying three things when ADR 0004 says four. The missing one is the
control plane's signing identity -- the reason a node does not have to trust
the broker it dials.

Without it the control plane's authority is transitive through the broker, and
0004 spells out what that costs: a compromised broker could forge declarations,
and since the host applies whatever the link delivers, that is the whole
machine. The record has the argument in full; the design doc had dropped the
conclusion.

Found by reading the two together while deciding what the control plane must
store, which is roughly the only way it would have been found -- both documents
are internally consistent and only disagree with each other.

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.
