Every module named its events the way the old bus spelled a routing key, so on the new bus every cross-module subscription pointed at a namespace nobody publishes to. Nothing failed — the services started and none of them reacted. Converted, and the rule now has checks at both scales: at registration for one manifest, and as a test across the whole catalogue where a consumed event's emitter is present. It was larger than the report said, in two directions nobody had looked. Forty-three files of module code pass the event name at runtime, so the code mattered as much as the manifests. And both clients had to learn the mapping — without that, converting the modules would have broken the mesh that is actually running, which is the opposite of what fixing this was for. Design 29 gained three things it did not say: what a wildcard is (`*` for one name, `**` for the rest, spelled the mesh's way and derived to each bus's own), that an event about a role belongs on the seat and why that is not yet possible, and how the rule is checked — because "a subscription that matches nothing is silence" is exactly why nobody noticed thirty-seven manifests being wrong the same way. 4.2 and 4.3 are unblocked. The catch-up half of 4.5 is not: it is a decision, and it narrowed rather than closed. It cannot be a reply to a module's inbox, because that needs the blanket grant design 25 §4 refuses.
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.
