All on the first three machines to actually run it, and all invisible from the mesh's own state: the graph was right, the files were right, the services were up, every node reported success, and the network did not work. A running interface does not re-read its configuration, so a node joining left every existing node carrying a network that no longer existed. A hub sharing a site with a spoke was emitted twice, which WireGuard refuses. Two nodes at one site that neither can be dialled were peered directly, so nobody opened the path and the more specific route blackholed -- this document's own warning arriving in its implementation. And Docker sets the FORWARD policy to DROP, so a hub with forwarding enabled still carried nothing between its spokes. The last one is the sharpest: the substrate at tier 1 silently breaks the network at tier 2, and nothing in either tier's state says so. None of these is reachable by reasoning, and each was found within minutes of a real machine trying it. That is the argument for the lab in one line.
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.
