Both lines of work numbered from the same point, so four decision records and one design document existed twice with different content. The trunk keeps its numbers and this branch yields — the only rule that scales, because the trunk's are already cited by what merged before them. 0117 the bus is the only broker -> 0125 0118 a module declares its own seats -> 0126 0119 amqp is a provision, not the bus -> 0127 0120 the mesh bus is required -> 0128 0123 a seat carries its role's protocol -> 0129 0124 the predecessor is ending -> 0130 design 29, what a module declares -> design 32 Applied to the code repositories too, because a stale reference is worse when numbers collide than when they dangle: the reader lands on a real record that decided something else. Two reconciliations the merge forced, both real: **0110 was marked wholly superseded and was not.** Its successor says in as many words that everything 0110 decided about what a seat *is* stands untouched — and two records that landed on the trunk rest on exactly that part. So it is accepted again, extended rather than replaced, with a note saying which of its claims moved and where. **A seat's protocol becomes columns, not fields.** The trunk moved the seat set out of compiled code into a table the controller owns. This branch had added what a role accepts, emits and serves to the Go slice. The decision is unaffected and the mechanism is better for it: giving a role a protocol is now a write rather than a rebuild, which is the trunk's own argument applied to what this branch added. One check still fails and it fails on main too: a record resting on ADR 0112 while that is still 'proposed'. Left alone — it is not this merge's to answer.
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.
