Everything should be able to call what runs on the same machine, another machine's service exposed to the private network, and another machine's service exposed publicly. Three cases; the filter had two. The first was expressed as the machines' own addresses on the private network. A caller on the machine carries such an address; a caller in one of its containers carries a bridge address and matched nothing — measured, same destination and same machine: src 10.10.0.1 against src 172.17.0.8. The second case worked by accident, because the tunnel rewrites a caller's address to the sending machine's. Two of three working is why it read as correct. 0143 answered the wrong question. It proposed verifying each grant from the consumer's own network position and went to length about which position, because whether a caller sat in a container changed the answer — and that difference was the bug. Observing a configuration error is not its remedy. Superseded, and nothing replaces it; whether the mesh should check a grant is still open in issue 145 and must stand on its own. And a module is not a container: 61 of 72 happen to use one, 11 do not, and a rule reasoning about containers describes most of the mesh rather than the mesh.
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.
